![]() Heat exchanger for latent heat accumulator
专利摘要:
The invention can be used to store heat using the heat of phase transition. The goal is to increase the heat transfer capacity and reduce material consumption by intensifying heat transfer. The device contains a case (K) 3 with heat storage substance (TB) 2, undergoing phase transformation in the range of operating temperatures, and intermediate heat carrier (PT) 1 in direct contact with it. In the latter there is a heating heat transfer surface 4. In K 3 is installed a heated heat exchange surface 5 and an additional heat exchanger from one or several pipes (T) 7 immersed in TB 2. T 7 are located along a conical surface with an angle of inclination to the horizontal. T 7 can be provided with lower and / or upper annular collectors 9 and 10 with the location of the latter in TB 2. T 7 can be performed with loop-shaped sections. T 7 can be made spiral. T 7 can only be equipped with a lower annular manifold and made with the upper ends plugged. The heating coolant, flowing through T 7 and the heating heat transfer surface 4, melts the TB 2, forming channel 8 therein and evaporates the PT 1 on the heat exchange surface 4. The bubbles of the PT 1 vapor rise through the channel 8 and condense on the heated heat exchange surface 5. Heat transfer between PT 1 and TB 2 is intensified due to the inclination of T 7, which improves the contact of steam bubbles and TB 2. 4 Cp f-ly, 4 ill. {l With about ate VJ 00 y 公开号:SU1657891A1 申请号:SU867774387 申请日:1986-12-22 公开日:1991-06-23 发明作者:Андреас Гюнтер;Уве Кеснер;Вольфганг Аренс;Христине Айльдерманн;Томас Фанггенель;Ганс-Гайнс Эмонс;Вольфганг ДИТРИХ;Рудигер Науманн 申请人:Академия Строительства (Инопредприятие); IPC主号:
专利说明:
The invention relates to heat engineering and can be used to accumulate heat using the heat of phase transition. The known technical solutions are mainly aimed at solving two types of problems: the use of substances with the greatest latent heat of the phase transition to increase compactness, as well as the use of substances and additional elements that compensate for the negative effect on heat exchange with the heat storage substance (GDR patent N 154126 , CL F 24 H 7/02, published 1982 (). For such technical solutions, the use of heat transporting media is characteristic, which are driven to increase the power of heat transfer and are in direct contact with the substance that changes the state of aggregation. Heat is transported using high-boiling liquids, such as oils, which are in a liquid state during heat exchange, or with low-boiling liquids, such as coolants, which evaporate and condense during heat exchange. At the same time, the insolubility condition of the contacting media is important one to another. Movement of heat transporting media can be carried out using pumps (USSR author's certificate No. 1455170, CL F 24 H 7/02. 14.07.86), or using natural convection, in particular, using boiling. In this case, the problem is the impermeability of the heat-accumulating substance in the solid phase. Mixing with it hard boiling liquids is either not possible or requires the use of high-pressure pumps. Stirring of low-boiling liquids is possible only through capillaries and cracks in a solid heat-accumulating substance, or through intermediate regions that appear when adding an accumulator to the substance of special additives in a crystalline form. In these areas, heat transfer is prevented by the counter-movement of rising steam and condensate flowing down. The closest to the present invention is a device (German Patent No. 3010625, Cl. C 09 K 5/02, published 1981), comprising a housing with a heat storage substance undergoing phase transformation in the range of operating temperatures and being in direct contact with it. intermediate heat carrier immersed in the last heating heat exchange surface, as well as the heated heat exchange surface and an additional heat exchanger from pipes immersed in a heat storage substance. In this device, the pipes of the additional heat exchanger, located vertically, melt around themselves a heat-storage substance, creating The latter has vertical channels for the circulation of the intermediate coolant, which improves the heat exchange in the case of using hard boiling intermediate heat carriers. A disadvantage of the known device is the low heat transfer power when using low-boiling intermediate heat transfer fluids due to the absence of contact between the intermediate vapor bubbles. heat carrier with heat storage substance in said vertical channels. The use of agents that increase the heat exchange surface in these channels and inside the heat-accumulating substance (fins, gratings, etc.) increases the consumption of materials and makes boiling and condensation difficult. The purpose of the invention is to increase the heat transfer capacity and reduce the material consumption of the device by intensifying heat exchange between the heat storage substance and the intermediate coolant. Figure 1 shows the proposed device; figure 2 - the same, with pipes of an additional heat exchanger, made with loop-shaped areas; on fig.Z - the same, with the pipe of the additional heat exchanger, made spiral; figure 4 is the same, with the pipes of the additional heat exchanger plugged. Heat exchanging device for dynamic accumulators of latent heat contains hermetic casing 3 s heat storage substance 2, which undergoes phase transformation in the range of operating temperatures, and intermediate heat carrier 1 which is in direct contact with it. 0 heating heat exchanging surface 4. A heated heat exchanging surface 5 and an additional heat exchanger from one or several pipes 7 are installed in the housing, immersed in a heat-accumulating substance 2. One or several pipes 7 of an additional heat exchanger are located along an imaginary conical surface with an angle of inclination a50-85 ° to horizontally. The pipes 7 of the additional heat exchanger can be provided with lower and / or upper annular manifolds 9 and 10, respectively, the latter being located in the zone of heat-accumulating substance 2. Pipe-7 additional heat exchanger can be performed with loop-shaped sections (figure 2). The pipe 7 of the additional heat exchanger can be made spiral and fully immersed in the heat-accumulated substance 2 (Fig. 3). The pipes 7 of the additional heat exchanger can be equipped only with the lower annular collector 9 and are made with plugged upper ends. The heat exchanging device is equipped with an inlet 14 and an outlet 15 of the chambers of the heating coolant, return pipe 6. Heats the heat exchange on the surface 5 installed in the heat removal zone 13. In the heat-accumulating substance 2, as a result of its melting, a channel 8 is formed. Positions II and 12 designate the directions of movement of the heating and heated coolants, respectively. A heat exchange device for dynamic accumulators of latent heat works as follows. The heating coolant is supplied from the chamber 14 to the heating heat-exchanging surface 4 and in parallel flow into one or several pipes of the additional heat exchanger. From the latter, the heating coolant after removing heat from it via the return line 6 enters the chamber 15 and is discharged from the device in direction 11. The heated coolant is supplied to the heated heat exchange surface 5 (the flow direction is indicated by the position 1.2), where it is heated, the heat from the intermediate heat carrier 1 is removed, and removed from the device to the heat consumer (not shown). When a heating coolant flows through one or several pipes 7, an additional heat exchanger, located in the heat-accumulating substance 2, the latter melts forming one or several channels 8 along the pipes 7, opening the intermediate heat carrier 1 to the heat removal zone 13 in the upper part of the housing 3 Simultaneously as a result of the heating heat carrier flowing through the heating heat-exchange surface 4 the intermediate heat carrier 1, filling the lower part of the housing 3 (which can be achieved due to the difference in the densities of the intermediate heat carrier 1 and the heat-closing cumulative substance 2), is evaporated heating the heat exchange surface 4. The resulting steam bubbles intermediate heat medium 1 are raised along the inclined channels (or rope) 8 Become 10 in contact with the not yet melted heat-accumulating substance 2, the melting point of the latter, of course, must be below the boiling point of the intermediate heat transfer medium 1. Steam 5 the bubbles heat up and melt the heat accumulator; the decaying substance 2 The intermediate heat carrier vapor 1 condenses on the heated heat exchange surface 5, giving off heat to the flow through it 0 to the heated coolant, and the condensate flows into the channel 8 and its wall again comes into contact with the heat accumulating substance 2. After reaching the heating heat-exchanging surface 4, the condensate is again 5 and the cycle repeats Experiments have shown that the flow of 8% of the heating coolant (from its full flow) through the tubes 7 of the additional heat exchanger, located, for example, at an angle and –78 ° to the horizontal, allows to increase the power of the heat exchanger for heat transfer by 20%. Heat transfer between intermediate 5 by heat carrier 1 and heat accumulating substance 2 is intensified due to the inclination of pipes 7 of additional heat exchanger, which ensures close contact of steam bubbles with heat storage substance 2.
