    US1993730A (Carpenter Walter E) of 03/03/1935 The inventor, in the process of preparation and development of prototypes has considered the convenience of introducing some modifications that improve the previous models being that the reason that leads him to present a new document that collects such modifications allowing to optimize said models. DESCRIPTION OF THE INVENTION
    The invention presented in this document describes certain modifications that perfect the two previous ones presented by the inventor mentioned in the previous section. The object of the invention is a modular device, applicable to any type of refrigerator, although, for reasons of clarity, this document focuses on a portable refrigerator with sufficient autonomy to be effective for about 48 hours. In the previous models, the tank containing the refrigerant product is installed inside the refrigerator which implies the inconvenience of having to transport the assembly to the place of recharge every time that recharge is needed. To overcome said drawback, the new model is projected in such a way that the refrigerant reservoir is outside the main body of the refrigerator having means that allow a firm and secure coupling on said main body. In this way, when a refrigerant refill is required, the tank will first be separated from the main body, then transported, in an isolated way, to the recharge point with the consequent advantages of comfort, saving in weight and volume transported. Once recharged, the coolant tank is attached to the main body of the refrigerator which causes the necessary physical connections to be established so that the cold generated by the progressive evaporation of the coolant
    It is transmitted inside the refrigerator with the consequent cooling of the products it contains. The inventor conceives a firm coupling between the tank and the refrigerator by means of male appendages that are introduced into the body of the refrigerator by adding, in addition, a series of permanent magnets that optimize said coupling. The operation is the same as in the previous inventions with the particularity that, depending on the needs, the number of connections between the tank and the refrigerator can be modified, which results in added savings and the achievement of a more efficient device. As a cooling element, carbon dioxide (C02), usually referred to as dry ice or carbonic snow, is preferably used. It receives this name because although it resembles normal ice or snow, due to its appearance and temperature, it does not leave a trace of moisture because its natural state is gaseous even at low ambient temperatures, with its sublimation temperature of -78.5 oC at atmospheric pressure. . Dry ice should be handled with caution (use of protective gloves), as it can cause burns due to excess cold being that property that is used to cool the products stored in the refrigerator until it is completely sublimated at which time a recharge Alternatively, liquid nitrogen could also be used which, at the pressure of an atmosphere, reaches -195.8 oC but is not recommended because of its greater danger. In general, the modular refrigerator of the invention can be operated with any liquefied gas, and its characteristics must therefore be known in terms of the temperatures reached when passing into the gas phase to adequately regulate the temperature desired to be inside the refrigerator . Although, as noted above, the figures included in this document, as an inseparable part thereof, refer to a small refrigerator, the invention is valid for many other applications among which we can mention the following:

    Rechargeable modular device for refrigerators (Figs. 1, 2, 3 and 4) which refers to the introduction of modifications that perfect two other similar devices conceived by the same inventor. The first, with application number P 201200879, published as ES 2454871 Bl, with Concession Title dated 23.02.2015 and the second one, with application number P 201500342, has not been published to date. In the preferred embodiment presented herein, it comprises a refrigerant tank (1) consisting of an external housing (2) and an internal wall (2.1) between which there is a filling of insulating material (3) having the said coolant tank (1) a straight prismatic shape on whose upper face two special valves are installed, one of which is the refill valve (4) and the other is the gas outlet valve (5). On one of the side faces of the refrigerant tank (1) it has at least four anchoring appendages (7) existing in the vicinity of each of
    they are permanent magnets (8) of high power of attraction such as the
    neodymium Inside the refrigerant tank (1), through the filling of insulating material, two, three or more collector resistors (6) are installed that protrude slightly outward in a conical shape. The said coolant tank (1), is airtight being able to alter said airtightness or by opening the refill valve (4) or by opening the gas outlet valve (5), and its functionality is to be coupled to a refrigerator (9) (Fig. 3) whose interior is protected with relatively thick walls of insulating material (3) similar to that of the refrigerant tank (1). To carry out said coupling as shown in (Fig. 3) the refrigerator (9) has as many holes as anchoring appendages (7) has the refrigerant reservoir (1) being its situation such that a perfect matching anchoring appendages (7) and refrigerator holes (9). The aforementioned coupling is secured in a very firm way by means of neodymium magnets (8), the coolant tank (1) and the refrigerator (9) being closely connected, with the particularity that, in addition, the pick-up resistors
    (6) establish a perfect contact with the thermo-conductive connections (11) inserted in the corresponding wall of the refrigerator (9) which are extended perimetrically in the form of metal sheets (12) by the interior walls of the refrigerator (9) as is schematized in (Figs. 3 and 4). The assembly formed by the refrigerant tank (1) and the refrigerator (9) works in such a way that the cold generated in the refrigerant tank (1) is transmitted to the refrigerator enclosure (9) by thermal conduction in a process that is initiated by the sublimation of the refrigerant introduced into the refrigerant tank (1) through the refill valve (4). The gas generated in the sublimation goes outside through the adjustable gas outlet valve (5), generating a very cold atmosphere inside the refrigerant tank (1) that cools the collection resistors (6) which transmit the cold to the thermoconductive connections (11) which, in turn, cool the sheets
    metallic (12) producing the final cooling of the products it contains
    the refrigerator (9).Since the temperature that carbonic snow has is very low then,as indicated above, at -78.5 oC, thetransfer of refrigerators from the refrigerant tank (1) to the refrigerator
    (9) since it does not interest that the interior of this one is too cold. The aforementioned regulation can be done at the thermo-conductive connection points (11) when it is a refrigerator in full use or, it can be foreseen in the design of the refrigerator itself depending on the use that will be given. Thus, in a beach fridge or in beverage or bottle coolers where the temperature must be close to about 4 oC, few metal sheets will be installed
    (12) but if you think of an ice cream cart where the indoor temperature should be around -4 oC, then the transmission of refrigerators should be increased by installing a greater number of metal sheets (12). In summary, the invention has many possibilities using the same principle of operation and dimensioning of the refrigerator in accordance with the use that will be given. The great advantage of the proposed invention is that it is an autonomous refrigeration device that does not require to be connected to the network during the period of use and is also portable, so that, in the case of the refrigerator represented in the drawings of This document can be easily transported for what has a handle (10) being able to dispose of its contents by opening the door (13) equipped with the handle (14) although, optionally, the front door (13) could be replaced by an upper cover folding or by a screw cap always taking care to design a good closing system to avoid losses. When the modular assembly has been used for one or two days, the refrigeration tank (1) is disconnected by moving it in isolation to the charging point without the need to move the refrigerator (9). As an additional advantage we can even mention that of water saving since, as has been exposed, the modular device of the invention does not require ice.
    It is not considered necessary to make the content of this description more extensive so that a person skilled in the art can understand its scope and the advantages derived from the invention, as well as develop and put into practice the object thereof.
    5 However, it should be understood that the invention has been described according to a preferred embodiment thereof, so it may be susceptible to modifications, such modifications may affect the shape, size and / or manufacturing materials without affecting it. or suppose any alteration of the basis of said invention. That is, the terms in which it has been
    10 exposed this preferred description of the invention, should always be taken broadly and not limitingly.
