    An advantage of compact hand-held devices is that they are particularly suitable for small and difficult-to-access surfaces. However, it is important to ensure that the handle assembly does not reach temperatures that can cause burns.
    OBJECT OF THE INVENTION The object of the invention is to provide a device for applying heat radiation to a surface, which device is adapted to be held by the wearer during use.
    BRIEF DESCRIPTION OF THE INVENTION An element connected to another element need not be directly connected to the other element. Additional elements may be arranged between the connected elements.
    The term "hook" refers to the degree to which a line deviates from being straight. The heat dissipating element can have a hook that varies between 0 and 180 °. The heat radiation intensity is defined as power per unit area, in it it has the text as W / cm2.
    The object of the invention is achieved with a device according to independent claim 1.
    The invention comprises a main assembly and a handle assembly connected to the main assembly. The main unit comprises at least one heat radiating element arranged in a reflector unit, which reflector unit has an opening intended to be directed towards the surface to be irradiated. The main unit and the handle unit are separated by a space and at least one heat dissipating element which crosses said space connects a first fixed area p5 the main unit and a second fixed area p5 the handle unit. At least a part of the heat-dissipating element has a slight curvature that the length of the heat-dissipating element exceeds the distance between the first and second solid areas.
    Heat is transferred from the main unit to the handle unit. The heat dissipating element is arranged between the main unit and the handle unit to ensure that a sufficient amount of heat is dissipated to the air surrounding the heat dissipating element when it is conducted away from the main unit, so that the handle unit maintains a suitable temperature. 3 It is advisable to increase the amount of heat dissipated to the air surrounding the warning-dissipating element. Heat is transferred from the heat dissipating element to the escaping air via the surface of the heat dissipating element. It is thus desirable to increase the surface area of the heat dissipating element. However, it is also desirable to use a thin, heat-dissipating element, since a heat-dissipating element with a larger diameter has better heat-conducting properties, which meant that more heat was transferred to the handle assembly. The solution is to use a hook heat dissipating element. A hook heat dissipating element can be made longer and with a larger surface area without increasing the thickness of the heat dissipating element. Consequently, the hook of the heat dissipating element improves the thermal insulating effect of the heat dissipating element. The heat-dissipating element stalls so that the handle unit is maintained at a suitable temperature and prevents burns.
    The heat dissipating element advantageously consists of a curved element of any suitable material, for example stainless steel.
    The length of the heat dissipating element is the distance between a first end portion of the heat dissipating member, which first end portion is connected to the first fixed area of the main unit, and a second end portion of the heat dissipating member, which second end portion is connected to the second fixed area of the handle assembly. The length of the heat dissipating element is measured along a line that follows the curvature of the heat dissipating element.
    A suitable length of the heat-dissipating element is advantageously in the range 100-600 mm. For example, Jr 315 mm a lamp length on a heat dissipating element mounted in a device with a heat radiation intensity of 9.25 W / cm2 and aperture dimensions of 90x72 mm.
    The heat dissipating element advantageously has a relatively thin cross-sectional area. The diameter of the heat dissipating element is advantageously in the range 1-5 mm and more advantageously in the range 1.5-4 mm. The heat dissipating element in the example described above may, for example, have a diameter of 2.8 mm. The diameter p5 of the heat dissipating element is the diameter p5 of the curved element constituting the heat dissipating element. 4 The cross-sectional area of the heat-dissipating element can have any suitable shape as a hoist. The heat dissipating element advantageously has a circular cross-sectional area.
    The handle assembly is advantageously at least partly made of a plastic material with good heat-insulating properties. The thermal insulation effect of the heat dissipating element ensures that the plastic material remains at a temperature below the melting point of the plastic material.
    The handle assembly may comprise a handle portion comprising a plurality of layers of plastic with different material properties. For example, the outermost layer may be softer than the innermost layer. The handle portion may also5 comprise only one plastic material layer.
    The heat dissipating element may have any suitable shape as lifted, as long as at least some of it is strong in the longitudinal direction of the heat dissipating element. Advantageously, most or all of the heat dissipating element is curved in the longitudinal direction of the heat dissipating element. The heat dissipating element may, for example, have an accordion-like shape or the shape of a helix. The heat dissipating element may, for example, be in the form of a helix or a spiral.
    The heat dissipating element is advantageously elastic and adapted to absorb movements of the main unit. The heat dissipating element may, for example, be adapted to absorb displacements in the longitudinal direction of the heat dissipating element. The heat dissipating element is advantageously connected to the reflector unit, in which case it is adapted to absorb movements of the reflector unit.
    In some embodiments, the heat dissipating element comprises a coil spring.
    In certain embodiments, the device may comprise more than one heat dissipating element connected to the main assembly and the handle assembly. This reduces the heat-dissipating surface and causes more heat to be dissipated to the surrounding air.
    The main unit is advantageously articulated connected to the handle unit, so that the main unit can be pivoted relative to the handle unit. The articulated main unit ensures that the device can be held in an ergonomic manner and makes it easier to reach difficult surfaces.
    The main unit is advantageously pivotable in any direction heist. In an alternative embodiment, the main unit is pivotable about a single axis.
    In the embodiments of the main assembly pivotally connected to the handle assembly, the heat dissipating element is advantageously pivotally connected to one or both of the main assembly and the handle assembly.
    The device comprises one or more heat radiating elements. A heat radiating element may comprise an electrical resistance. If there are two or more heat radiation elements, these can run parallel to each other.
    The heat radiating element advantageously uses a cold father infrared radiation for heating the coating, such as the said electrical resistance wire. It is possible to use other electric heat radiation sources, such as microwave devices.
    The removal of paint is usually carried out manually by physically removing the paint after it has been heated, for example by scraping.
    The reflector unit is advantageously mounted in a housing which accommodates at least a part of the reflector unit. The casing can be formed by extrusion and is advantageously made of aluminum. The cover acts as a protective cover and prevents a user from coming into direct contact with the reflector unit. A reflector unit in a handheld device can, for example, be heated up to about 600 ° C.
    The reflector unit is intended to amplify the heat radiation and the direction of the heat radiation by reflecting the heat radiation generated by said heat radiation element in the direction of the opening. The reflector unit can have many different shapes and include the number of heat radiation elements that are raised. The reflector unit may, for example, comprise a reflecting metal plate arranged in the housing, which reflecting metal plate may have a wave-shaped reflecting rear cradle suitable for two or more heat radiating elements or alternatively a flat reflecting rear cradle suitable for a single heat radiating element. The reflector unit may further comprise reflective side cradles, which are suitably angled, so that the heat radiation is directed towards the surface to be treated via the opening.
    Alternatively, the housing itself may comprise side cradles, which are suitably angled and at least partially emit reflective surfaces which partly surround the heat radiation element, advantageously in combination with a reflecting rear cradle, which can also form part of the housing. The device is advantageously provided with spacer elements for maintaining a suitable distance between the device and the surface to be treated. A suitable distance between the above-mentioned at least one electrical resistance wire and the surface is 3-15 cm.
    The coating to be deposited is usually heated to a temperature in the range of 100-200 ° C, advantageously in the range of 110-165 ° C.
    Throughout this application, the term infrared straining refers to electromagnetic radiation having a wavelength of from about 0.7 microns to about 1000 microns. A suitable wavelength for the removal of most types of paints and coatings is about 3 pm and optimal absorption for a starting number of different substances is in the range 1-3.5 p.m.
    The term coating includes all kinds of compounds that have previously been applied to a surface, for example paint and different kinds of plastic coatings. The term color includes, but is not limited to, oil, water and / or plastic based paints. Different types of varnishes are also conceivable.
    A surface is the outermost part of a construction element, for example a cradle or a floor. A structural element may be made of one or more materials, including but not limited to tra, concrete or plgt.
    The heating device has been described for removing paint, which is the intended main purpose of the heating device, but it can of course be used for other heating purposes as well, such as drying. Water has an absorption maximum for IR radiation with a wavelength of 3 μm and a device which is suitable for color removal is thus also usable for heating water. Additional areas of use for the heating device for heating surfaces are Aldan tankable.

DETAILED DESCRIPTION OF THE INVENTION The invention will now be described with reference to the accompanying drawings, in which identical male reference numerals refer to similar or corresponding parts.
    Figure 1 shows a perspective view of a first embodiment of a device 1 for applying heat radiation to a surface. The device 1 comprises a main assembly 2 and a handle assembly 3 separated by a space. The device has a longitudinal axis L and a transverse axis T.
    Referring now to Figures 1 and 2, the main assembly 2 includes a reflector unit 4 mounted in a protective housing 5. A heat radiating element 6 comprising a plurality of electrical resistors arranged in a tube made of quartz crystal is mounted in a reflector unit 4. The reflector unit 4 comprises a U-shaped center part 4a and tv5 side cradles 4b, 4c connected to the center part, so that they define a space enclosed on four sides, which space houses the heat radiation element 6. The center part 4a and the side cradles 4b, 4c also define an opening intended to be directed towards the surface to be treated. The reflector unit 4 is thus adapted to reflect the radiation from the heat radiation element 6 in the direction of the surface to be treated.
    Those skilled in the art will appreciate that the shape of the reflector unit 4 can be modified in many different ways without falling outside the scope of the invention.
    The housing 5 comprises two separate housing parts 5a, 5b, which thank a large part of the center part 4a of the reflector unit 4 and side cradles 4b, 4c. The housing 5 is designed by extrusion and advantageously made of aluminum. The housing 5 functions as a protective housing which prevents a user from coming into direct contact with the reflector unit 4, which can be heated to temperatures of about 600 ° C during use of the device 1.
    Figure 3 is an exploded view showing how the main assembly 2 is articulated connected to the handle assembly 3.
    The handle assembly 3 comprises a handle portion 21 and a first bracket 7. The first bracket 7 comprises a first spirit connected to the handle portion 21 and a second spirit coated opposite the first spirit seen in the longitudinal direction of the device 1. The second duct comprises two thin duck portions 7a, 7b with a circular transverse section seen in the transverse direction of the device 1. The duct portions 7a, 7b are coated opposite each other along the transverse axis T and run in respective planes perpendicular to the transverse axis T. The duck portions 7a, 8 7b are articulated p5 pins 22 (only one is shown in figure 3) which run through centrally coated through holes. hal i andpartierna 7a, 7b.
    Each housing part 5a, 5b is rigidly connected to a respective mounting arm 10, 11. Each mounting arm 10, 11 runs from its corresponding housing part 5a, 5b in the direction of the handle assembly 3. Each mounting arm 10, 11 has an outermost section 10a, 11a (mounted on distance from the housing 5) and the usual outermost section 10a, 11a have an extension in a plane perpendicular to the transverse axis T of the device 1. Each duct section 10a, 11a has a continuous hall adapted to receive a fastening element 8, 9. In this embodiment the fastening elements are 8, 9 screws. Other types of fasteners 8 are possible. The duck sections 10a, 11a are coated outside the duck portions 7a, 7b of the first bracket 7 seen in the transverse direction of the device 1.
    The main assembly 2 can be rotated about the transverse axis T of the device by means of a main assembly positioning means 12. That is, the main assembly positioning means 12 can be used to adjust the angular position of the main assembly 2. The main unit positioning means 12 comprises a longitudinally stretched and curved rod 12a, which at opposite spirits is connected to two connecting elements 12b, 12c. Each connecting element 12b, 12c has a circular cross-section seen in the transverse direction of the device 1 and comprises a center hall with an extension along the transverse axis T of the device 1. Each h51 is adapted to receive one of the fixed elements 8, 9. The insides of the flange are threaded and Wens & Igor is adapted to cooperate with corresponding passages on the fastening elements 8, 9. Washers are arranged outside the duck sections 10, 11a of the mounting arms 10, 11. Each fastening element 8, 9 extends through one of the washers, through the through-hole in one of the duck sections 10a, 11a. the mounting arms 10, 11 and into the cavity of one of the connecting elements 12b, 12c. The fastening elements 8, 9 are tightened in the tail to force the end sections 10a, 11a of the mounting arms 10, 11 into frictional contact with the connecting elements 12b, 12c. Thus, it is ensured that the housing 5 rotates with the main assembly positioning means 12.
    A heat dissipating element 13 adapted to conduct heat away from the reflector unit 4 is mounted between the main assembly 2 and the handle assembly 3. The heat dissipating element 13 is welded at a first end to a fastening element 24 at a first fixed area 14. The fastening element 24 is fixed to a second bracket 15 by means of a pair of screws (not shown) and the second bracket 15 is fixed to the reflector unit 4. The heat dissipating element 9 13 also has a second spirit welded to a third bracket 17 at a second fixed area 16. The first spirit of the heat dissipating element 13 is coated opposite the second second of the heat dissipating element 13 seen in the longitudinal direction of the heat dissipating element 13. The third bracket 17 is part of the handle assembly 3 and the second bracket 15 is part of the main assembly 2, so that the heat dissipating element 13 extends from the main assembly 2 to the handle assembly 3.
    The second bracket 15 branches the center portion 4a of the reflector unit 4 and is adapted to conduct heat from the reflector unit 4 to the heat dissipating element 13 via the fastening element 24. A part of the arm which is transferred to the heat dissipating element 13 is dissipated to the air surrounding the heat dissipating element 13 and a part of it is led to the handle assembly 3.
    The third bracket 17 comprises a base portion 17a connected to the heat dissipating element 13 and two legs 17b, 17c which are connected to and run in the direction away from the base portion 17a. The legs 17b, 17c run parallel in a plane perpendicular to the transverse axis T of the device. The two legs 17b, 17c are spaced apart from each other along the transverse axis 1. Each leg 17b, 17c is connected to a corresponding connecting element 12b, 12c has the main assembly 12 by means of one of the above-mentioned pins 22 (only one is shown). The pins 22 ensure that the third bracket 17 and thus the reflector unit 4 rotates with the main unit positioning means 12 and the housing 5. As mentioned above, the pins 22 run through the centrally located through holes in the duct portions 7a, 7b having the first bracket 7, so that the main unit 2 is allowed to rotate. the transverse axis T of the device in relation to the handle assembly 3.
    A stop element 23 runs between the inner surfaces of the duck portions 7a, 7b. The stop element 23 runs through grooves in the semicircular peripheries of the legs 17b, 17c. The spirits of the springs are adapted to cooperate with the stop element 23 to prevent the main assembly 2 from rotating further in relation to the handle assembly 3. In this embodiment the main assembly 2 is allowed to rotate relative to the handle assembly 3 by an angle 0 about the transverse axis T of the device 1.
    The heat dissipating element 13 shown in Figures 1-3 is a helical spring. That is, the heat dissipating element is curved and has the shape of a helix, so that the length of the heat dissipating element 13 exceeds the distance between the first and second fixed areas 14, 16. Thus, it is also stated that the surface area of the heat dissipation element 13 is larger than the surface area of a straight heat dissipation element of the same diameter. The larger surface area ensures that more water is diverted from the heat dissipating element 13 to the ambient air and the increased length ensures that the distance that the arm has to travel along the heat dissipating element 13 is increased. The result is that less heat is transferred from the main assembly 2 to the handle portion 21 of the handle assembly 3.
    The handle assembly 3 also comprises electrical components housed in the handle portion 21. The handle portion 21 is made of plastic. The heat dissipating element 13 ensures that the amount of heat dissipated from the main assembly 2 to the handle portion 21 of the handle assembly 3 is not sufficient to melt the plastic in the handle portion 21.
    In summary, the hooking of the heat dissipating element 13 ensures that a sufficient amount of heat is dissipated to the air surrounding the heat dissipating element 13, so that the temperature of the handle portion 21 is maintained at a level 5 which allows a user to hold the handle portion without burning.
    The heat dissipating element 13, which is a coil spring, is also adapted to absorb a part of the movements of the main assembly 2 and the handle assembly 3. This arrangement makes it possible for the device 1 to resist impact forces which are generated upon contact with other elements, for example a floor or a cradle.
    The elasticity of the heat dissipating element 13 and the articulated connection between the main assembly 2 and the handle assembly 3 make the device 1 advantageous 5x / one from an ergonomic point of view, in these features it is possible for a user to maintain the handle assembly 3 in substantially the same position regardless of position 2.
    In an alternative embodiment of the invention, the device may comprise two or more heat dissipating elements 21 connecting the main unit 2 and the handle assembly 3. The addition of a second heat dissipating element 13 further increases the total surface area of the heat dissipating elements 13 and ensures that more heat is dissipated to the escaping air.
    In an alternative embodiment, the main assembly 2 may be rigidly connected to the handle assembly 3.
    In an alternative embodiment, the main assembly 2 can be connected to the handle assembly only by means of one or more heat dissipating elements 13. The saw mounting arms 10, 11 connecting the housing parts 5a, 5b and the handle assembly 3 are optional.
    The dimensions of the device 1 are not essential to the invention. The device 1 is advantageously intended to be simple to use as a hand-held device, although assisting holding devices can be used to line and position the device. A lamp device 1 can, for example, have an elongated opening in the reflector unit 4 with a width ph '90 mm and a height p5 72 mm.
    Heat dissipating elements can also be used in larger devices intended to be mounted on one or more support structures.
    The invention is not limited to the embodiments described above but can be varied within the scope of the following claims. The embodiments and features described above can also be combined in several different ways. The device shown in Figures 1-3 may for instance comprise tv5 or more heat dissipating elements with a spiral shape and the mounting arms may be removed (the housing 5 may be connected to the reflector unit 4 in many different ways). 12
