Description

[0001] This utility model claims priority to patent application No. 2025108453116, with a priority date of June 23, 2025. Technical Field

[0002] This utility model relates to the field of heat exchange technology, and more specifically, to a subcooled condenser and a thermal management system. Background Technology

[0003] Currently, plate heat exchangers are commonly used in thermal management systems to heat cooling water. High-temperature, high-pressure gaseous refrigerant enters the plate heat exchanger and exchanges heat with the cooling water, transferring heat to the water. During this process, the superheated gaseous refrigerant first cools down to a two-phase state (gas and liquid), and then the liquid phase gradually increases until all the gaseous refrigerant becomes liquid. However, current plate heat exchangers cannot further cool the liquid refrigerant (to a subcooled state), thus preventing further heating of the cooling water, resulting in low heat exchange efficiency and poor heat exchange performance.

[0004] Therefore, designing and manufacturing a subcooled condenser with high heat exchange efficiency and good heat exchange performance, as well as a thermal management system, is particularly important, especially during the heat exchange process. Utility Model Content

[0034] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0035] Please refer to the reference. Figures 1 to 6 ( Figure 2 The hollow arrow in the image indicates the direction of refrigerant flow. Figure 3 The hollow arrows in the figure indicate the direction of cooling water flow. This embodiment of the invention provides a thermal management system (not shown) for heating cooling water. It can achieve stable subcooling of the refrigerant, effectively improve heat exchange efficiency, enhance heat exchange performance, and rationally arrange the flow length of the refrigerant under different states to reduce refrigerant flow resistance and reduce energy consumption.

[0036] The thermal management system includes a subcooled condenser 100, a compressor (not shown), an evaporator (not shown), and a throttling device (not shown). The compressor, subcooled condenser 100, throttling device, and evaporator are connected end-to-end to form a refrigerant flow channel for refrigerant circulation. The compressor performs work to convert the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The subcooled condenser 100 exchanges heat with cooling water to convert the high-temperature, high-pressure gaseous refrigerant into a low-temperature, high-pressure liquid refrigerant. The throttling device throttles the low-temperature, high-pressure liquid refrigerant to convert it into a low-temperature, low-pressure liquid refrigerant. The evaporator exchanges heat with the refrigerant to convert the low-temperature, low-pressure liquid refrigerant into a low-temperature, low-pressure gaseous refrigerant.

[0037] The subcooled condenser 100 includes a liquid storage element 110, a plurality of first plates 120, a plurality of second plates 130, and a plurality of spacers 140. The plurality of first plates 120 and the plurality of second plates 130 are arranged alternately in sequence. A first heat exchange channel 150 is formed between a first plate 120 and an adjacent second plate 130, and a second heat exchange channel 160 is formed between a first plate 120 and another adjacent second plate 130. That is, the plurality of first plates 120 and the plurality of second plates 130 together form a plurality of first heat exchange channels 150 and a plurality of second heat exchange channels 160. The plurality of first heat exchange channels 150 and the plurality of second heat exchange channels 160 are arranged alternately in sequence, and the plurality of first heat exchange channels 150 and the plurality of second heat exchange channels 160 are connected in sequence. The first heat exchange channel 150 is used for the circulation of refrigerant, and the second heat exchange channel 160 is used for the circulation of cooling water. The refrigerant is used to exchange heat with the cooling water through the first plate 120 and the second plate 130 to achieve the function of heating the cooling water.

[0038] Furthermore, the number of partitions 140 is the same as the number of first heat exchange channels 150. Each partition 140 is disposed within a first heat exchange channel 150 to divide the first heat exchange channel 150 into a condensing channel 151 and a subcooling channel 152. The volume of the condensing channel 151 is larger than the volume of the subcooling channel 152. The condensing channel 151 is used for the flow of gaseous refrigerant, gas-liquid two-phase refrigerant, or liquid refrigerant, while the subcooling channel 152 is used for the flow of liquid refrigerant. Specifically, the condensing channel 151 is connected to the subcooling channel 152 through a liquid storage device 110. The liquid storage device 110 is used to store refrigerant to enhance the adaptability of the thermal management system. The liquid storage device 110 also provides gas-liquid separation to ensure subsequent refrigerant subcooling.

[0039] It should be noted that during the process of the high-temperature and high-pressure gaseous refrigerant flowing into the subcooled condenser 100, the high-temperature and high-pressure gaseous refrigerant first enters the condensation channel 151 and exchanges heat with the cooling water through the first plate 120 and the second plate 130 to achieve the function of heating the cooling water. During this process, the high-temperature and high-pressure gaseous refrigerant releases heat and cools down to become a low-temperature and high-pressure gaseous refrigerant, and gradually becomes a gas-liquid two-phase refrigerant, or may completely become a liquid refrigerant. Subsequently, the gas-liquid two-phase refrigerant or the liquid refrigerant enters the liquid storage device 110, where the refrigerant is separated into gas and liquid phases, and the liquid refrigerant is input into the subcooling channel 152. Then, the liquid refrigerant in the subcooling channel 152 continues to exchange heat with the cooling water through the first plate 120 and the second plate 130, so that the liquid refrigerant further releases heat and cools down to reach a subcooled state, improving the heat exchange efficiency and further improving the heating effect on the cooling water. Finally, the low-temperature and high-pressure liquid refrigerant is output from the subcooling channel 152 and reaches the throttling device.

[0040] In this way, firstly, the liquid storage device 110 is connected between the condensing channel 151 and the subcooling channel 152, which can realize stable subcooling of the refrigerant, effectively improve heat exchange efficiency, and enhance heat exchange performance; secondly, the volume of the condensing channel 151 is larger than the volume of the subcooling channel 152, that is, the flow length of the refrigerant in the condensing channel 151 is greater than the flow length of the refrigerant in the subcooling channel 152, so that the flow length of the refrigerant under different states is reasonably arranged, reducing the refrigerant flow resistance and reducing energy consumption; thirdly, the condensing channel 151 and the subcooling channel 152 are both set in the first heat exchange channel 150, that is, the condensing channel 151 and the subcooling channel 152 are both located in the same layer structure, so that the subcooled condenser 100 only needs to be composed of two different types of plates (the first plate 120 and the second plate 130), reducing production costs.

[0041] In this embodiment, the input end of the first heat exchange channel 150 and the output end of the second heat exchange channel 160 are both located at one end of the subcooled condenser 100 along its length, and the output end of the first heat exchange channel 150 and the input end of the second heat exchange channel 160 are both located at the other end of the subcooled condenser 100 along its length. That is, the flow direction of the refrigerant in the first heat exchange channel 150 is opposite to the flow direction of the cooling water in the second heat exchange channel 160. By using the counter-current flow of the refrigerant and cooling water, the relative flow velocity of the refrigerant and cooling water can be maximized, further improving the heat exchange effect of the refrigerant and cooling water, thereby improving the heating efficiency of the cooling water. However, this is not the only embodiment. In another embodiment, the input end of the first heat exchange channel 150 and the input end of the second heat exchange channel 160 are both located at one end of the subcooled condenser 100 along its length, and the output end of the first heat exchange channel 150 and the output end of the second heat exchange channel 160 are both located at the other end of the subcooled condenser 100 along its length. That is, the flow direction of the refrigerant in the first heat exchange channel 150 is the same as the flow direction of the cooling water in the second heat exchange channel 160. In another embodiment, a flow guiding structure is provided at the top of the subcooled condenser 100 to guide the refrigerant output from the output end of the first heat exchange channel 150 to the vicinity of the output end of the second heat exchange channel 160, so as to achieve the same-side output of refrigerant and cooling water. In yet another embodiment, the output end of the second heat exchange channel 160 is located at the bottom of the subcooled condenser 100 so that cooling water is output from below.

[0042] Specifically, the subcooled condenser 100 is rectangular in shape, and the partition bar 140 extends along the width of the subcooled condenser 100 to divide the first heat exchange channel 150 into a condensing channel 151 and a subcooling channel 152 arranged along the length of the subcooled condenser 100. That is, the condensing channel 151 and the subcooling channel 152 are arranged sequentially along the length of the subcooled condenser 100. The input end of the condensing channel 151 (i.e., the input end of the first heat exchange channel 150), the output end of the condensing channel 151, the input end of the subcooling channel 152, and the output end of the subcooling channel 152 (i.e., the output end of the first heat exchange channel 150) are arranged sequentially along the length of the subcooled condenser 100. That is, the flow direction of the refrigerant in the condensing channel 151 is the same as the flow direction of the refrigerant in the subcooling channel 152, and both are opposite to the flow direction of the cooling water in the second heat exchange channel 160, thereby improving heat exchange efficiency and enhancing heat exchange performance. However, this is not the only option. In other embodiments, the subcooled condenser 100 may be elliptical, circular, or triangular, and the shape of the subcooled condenser 100 is not specifically limited.

[0043] During the heat exchange process of the subcooled condenser 100 with the cooling water, the refrigerant is introduced into the condensing channel 151 and flows through the liquid storage device 110 to the subcooling channel 152, while the cooling water is introduced into the second heat exchange channel 160. In this process, the refrigerant in one first heat exchange channel 150 (including one condensing channel 151 and one subcooling channel 152) can simultaneously exchange heat with the cooling water in two adjacent second heat exchange channels 160, resulting in a good heat exchange effect.

[0044] The first plate 120 includes a first plate body 121 and a first extension ring 122 and a second extension ring 123 connected to the first plate body 121. The first extension ring 122 and the second extension ring 123 are disposed opposite to each other on both sides of the first plate body 121. In this embodiment, the first extension ring 122, the second extension ring 123 and the first plate body 121 are integrally formed to improve the connection strength. A spacer 140 is connected to the first plate body 121, and the first plate body 121 can limit and fix the spacer 140.

[0045] The second plate 130 includes a second plate body 131 and a third extension ring 132 and a fourth extension ring 133 connected to the second plate body 131. The third extension ring 132 and the fourth extension ring 133 are disposed opposite to each other on both sides of the second plate body 131. In this embodiment, the third extension ring 132, the fourth extension ring 133 and the second plate body 131 are integrally formed to improve the connection strength. A spacer 140 is connected between the first plate body 121 and the second plate body 131 to realize the isolation function of the condensation channel 151 and the subcooling channel 152.

[0046] Furthermore, the first plate body 121 has a first through hole 124 and a second through hole 125 spaced apart, and the second plate body 131 has a third through hole 134 and a fourth through hole 135 spaced apart. The third through hole 134 is at least partially aligned with the first through hole 124 along the height direction of the subcooled condenser 100, and the fourth through hole 135 is at least partially aligned with the second through hole 125 along the height direction of the subcooled condenser 100. A first extension ring 122 surrounds the first through hole 124 and is connected to an adjacent second plate body 131 and communicates with the third through hole 134 to ensure that the first heat exchange channel 150 and the second heat exchange channel 160 are separated to prevent liquid mixing. A second extension ring 123 surrounds the second through hole 125 and is connected to another adjacent second plate body 131 and communicates with the fourth through hole 135 to ensure that the first heat exchange channel 150 and the second heat exchange channel 160 are separated to prevent liquid mixing.

[0047] In this embodiment, the third extension ring 132 surrounds the third through hole 134 and is coaxially arranged and connected to the first extension ring 122 of an adjacent first plate 120. The third extension ring 132 and the first extension ring 122 work together to ensure the separation effect and facilitate installation. The fourth extension ring 133 surrounds the fourth through hole 135 and is coaxially arranged and connected to the second extension ring 123 of another adjacent first plate 120. The fourth extension ring 133 and the second extension ring 123 work together to ensure the separation effect and facilitate installation. Specifically, the spacer strip 140 is welded between the first plate body 121 and the second plate body 131, the third extension ring 132 and the first extension ring 122 are welded, and the fourth extension ring 133 and the second extension ring 123 are welded to improve the connection strength and sealing performance.

[0048] Preferably, the first plate 120 further includes a first overlapping edge 126, which surrounds the first plate body 121. The spacer 140 is connected to the first overlapping edge 126 to ensure that the condensing channel 151 and the subcooling channel 152 are separated to prevent liquid mixing. The second plate 130 further includes a second overlapping edge 136, which surrounds the second plate body 131. The first overlapping edge 126 is connected to the second overlapping edge 136 to ensure the sealing of the first heat exchange channel 150 and the second heat exchange channel 160 to prevent leakage.

[0049] In this embodiment, regarding the first plate body 121 and its adjacent first heat exchange channel 150 and second heat exchange channel 160, the first heat exchange channel 150 (condensation channel 151 and subcooling channel 152) is located on the upper side of the first plate body 121, and the second heat exchange channel 160 is located on the lower side of the first plate body 121. The first extension ring 122 extends downward from the first plate body 121 to separate the second heat exchange channel 160. At this time, the first extension ring 122 is connected to the first heat exchange channel 150. The first extension ring 122 is used for refrigerant flow, that is, the first through hole 124 of the first plate body 121 and the third through hole 134 of the second plate body 131 are both used for refrigerant flow. The second extension ring 123 extends upward from the first plate body 121 to separate the first heat exchange channel 150. At this time, the second extension ring 123 is connected to the second heat exchange channel 160. The second extension ring 123 is used for cooling water flow, that is, the second through hole 125 of the first plate body 121 and the fourth through hole 135 of the second plate body 131 are both used for cooling water flow.

[0050] Accordingly, with regard to the second plate body 131 and its adjacent first heat exchange channel 150 and second heat exchange channel 160, the first heat exchange channel 150 is located on the lower side of the second plate body 131, and the second heat exchange channel 160 is located on the upper side of the second plate body 131. The third extension ring 132 extends upward from the second plate body 131 to separate the second heat exchange channel 160. At this time, the third extension ring 132 is connected to the first heat exchange channel 150. The third extension ring 132 is used for refrigerant flow, that is, the first through hole 124 of the first plate body 121 and the third through hole 134 of the second plate body 131 are both used for refrigerant flow. The fourth extension ring 133 extends downward from the second plate body 131 to separate the first heat exchange channel 150. At this time, the fourth extension ring 133 is connected to the second heat exchange channel 160. The fourth extension ring 133 is used for cooling water flow, that is, the second through hole 125 of the first plate body 121 and the fourth through hole 135 of the second plate body 131 are both used for cooling water flow.

[0051] It is worth noting that there are four first through holes 124, four third through holes 134, and four first extension rings 122, and two second through holes 125, two fourth through holes 135, and two second extension rings 123. That is, each first plate body 121 has four first through holes 124 and two second through holes 125, and each second plate body 131 has four third through holes 134 and two fourth through holes 135. The four first through holes 124 of the first plate body 121 are connected to the four third through holes 134 of the second plate body 131 through four first extension rings 122 and four third extension rings 132, respectively. The two fourth through holes 135 of the second plate body 131 are connected to the two second through holes 125 of the next first plate body 121 through two fourth extension rings 133 and two second extension rings 123, respectively.

[0052] Specifically, the first plate body 121 is rectangular. Two second through holes 125 are arranged opposite each other along one diagonal of the first plate body 121; a first first through hole 124 and a second first through hole 124 are arranged opposite each other along the other diagonal of the first plate body 121; a third first through hole 124 is disposed along the length of the first plate body 121 between the first first through hole 124 and a second through hole 125; and a fourth first through hole 124 is disposed along the length of the first plate body 121 between the second first through hole 124 and another second through hole 125. In other words, the first through hole 124, the third through hole 124, and the second through hole 125 are all connected to the condensing channel 151.
