Description

Technical Field

[0001] This application relates to the field of heat exchange technology, and in particular to a heat exchange component and heat exchange equipment. Background Technology

[0002] Equipment in outdoor server racks or server rooms generates a significant amount of heat during continuous operation, and this sustained temperature rise can negatively impact the equipment's operating efficiency. Currently, heat exchangers combining compression refrigeration cycles and heat pipes are used to dissipate heat from this equipment. The heat exchanger operates in heat pipe mode at low ambient temperatures and in vapor compression mode at high ambient temperatures, significantly improving system performance. However, to ensure compatibility with heat pipe mode operation, the pressure drop of the heat exchanger cannot be too large, and the flow path within the heat exchanger uses a dual-row parallel configuration. When switching to compression refrigeration mode, the heat exchanger's performance is poor due to the low flow rate of the heat exchange medium and the low heat transfer coefficient. Summary of the Invention

[0003] This application provides a heat exchange component and a heat exchange device.

[0004] In a first aspect, this application provides a heat exchange assembly, comprising a valve assembly, a first manifold, a second manifold, and a first heat exchange tube group and a second heat exchange tube group located between the first and second manifolds. The first manifold contains a first cavity and a second cavity that are connected to each other, while the second manifold contains a third cavity and a fourth cavity that are isolated from each other. The two ends of the first heat exchange tube group are respectively connected to the first cavity and the third cavity, and the two ends of the second heat exchange tube group are respectively connected to the second cavity and the fourth cavity. The valve assembly is connected to the first manifold, the third cavity, and the fourth cavity, and is used to receive a heat exchange medium at a first temperature. The heat exchange assembly includes a first heat exchange mode and a second heat exchange mode. When using the first heat exchange mode, the first manifold is connected to the valve assembly and receives the heat exchange medium at the first temperature through the valve assembly. The third chamber and the fourth chamber are connected through the valve assembly. When using the second heat exchange mode, the third chamber is connected to the valve assembly and receives the heat exchange medium at the first temperature through the valve assembly. The heat exchange medium at the first temperature passes through the first heat exchange tube group and the second heat exchange tube group and then outputs the heat exchange medium at the second temperature from the fourth chamber.

[0005] In the first heat exchange mode, the heat exchange assembly has two parallel flow paths. The flow direction of the heat exchange medium in the first and second heat exchange tube groups is the same. In the second heat exchange mode, the heat exchange assembly has one series flow path. The flow direction of the heat exchange medium in the first and second heat exchange tube groups is opposite.

[0006] The heat exchange component provided in this application can switch between a first heat exchange mode and a second heat exchange mode. Selecting different heat exchange modes according to different heat exchange requirements can save energy. Switching between different flow paths in different heat exchange modes can effectively improve the heat exchange performance of the heat exchange component.

[0007] In this application, on the one hand, the parallel flow path is adopted in the first heat exchange mode, which reduces the flow velocity of the heat exchange medium and the pressure drop of the heat exchange components. The resistance encountered by the heat exchange medium when flowing in the heat exchange components is smaller, which is more conducive to the flow of the heat exchange medium in the heat exchange components, thereby improving the performance of the heat exchange components. On the other hand, the series flow path is adopted in the second heat exchange mode, which makes the flow velocity of the heat exchange medium in the heat exchange components faster, the heat transfer coefficient higher, and the heat exchange effect better.

[0008] In one implementation, the valve assembly includes a first connection port, a second connection port, and a third connection port, which are respectively connected to a first manifold, a third cavity, and a fourth cavity. When heat exchange is performed using a first heat exchange mode, the inlet of the valve assembly is connected to the first connection port, and the second and third connection ports are connected. When heat exchange is performed using a second heat exchange mode, the inlet of the valve assembly is connected to the second connection port.

[0009] When using the first heat exchange mode, one flow path in the heat exchange assembly is as follows: the heat exchange medium enters the heat exchange assembly from the inlet of the valve assembly, and sequentially passes through the first connection port, the first manifold, the first heat exchange tube group, the third cavity, the second connection port, the third connection port, and the fourth cavity, and then flows out of the fourth cavity to the outside of the heat exchange assembly. The other flow path in the heat exchange assembly is as follows: the heat exchange medium enters the heat exchange assembly from the inlet of the valve assembly, and sequentially passes through the first connection port, the first manifold, the second heat exchange tube group, and the fourth cavity, and then flows out of the fourth cavity to the outside of the heat exchange assembly.

[0010] In one embodiment, the valve assembly is a five-way valve.

[0011] In this application, multiple interfaces are set on the valve assembly, and only one valve is needed to control the flow path switching of the first heat exchange mode parallel operation and the second heat exchange mode series operation of the heat exchange assembly. The implementation method is relatively simple and facilitates the application of the heat exchange assembly.

[0012] In one implementation, the valve assembly includes a first valve and a second valve. The first valve is connected to a first manifold and a third cavity, and the second valve is connected to the third cavity and a fourth cavity. The first valve is used to receive a heat exchange medium at a first temperature. When heat exchange is performed using a first heat exchange mode, the first manifold is connected to the first valve and receives the heat exchange medium at the first temperature through the first valve, while the third and fourth cavities are connected through the second valve. When heat exchange is performed using a second heat exchange mode, the third cavity is connected to the first valve and receives the heat exchange medium at the first temperature through the first valve, and the second valve is closed.

[0013] When using the first heat exchange mode, one flow path within the heat exchange assembly is as follows: the heat exchange medium enters the heat exchange assembly through the first valve, and sequentially passes through the first manifold, the first heat exchange tube group, the third cavity, the second valve, and the fourth cavity, before flowing out of the fourth cavity to the outside of the heat exchange assembly. The other flow path within the heat exchange assembly is as follows: the heat exchange medium enters the heat exchange assembly through the first valve, and sequentially passes through the first manifold, the second heat exchange tube group, and the fourth cavity, before flowing out of the fourth cavity to the outside of the heat exchange assembly.

[0014] When heat exchange is performed using the second heat exchange mode, the flow path within the heat exchange assembly is as follows: the heat exchange medium enters the heat exchange assembly from the first valve, and passes sequentially through the third cavity, the first heat exchange tube group, the first manifold, the second heat exchange tube group, and the fourth cavity, and flows out from the fourth cavity to the outside of the heat exchange assembly.

[0015] In this application, the valve assembly includes two valves. On the one hand, the flow path switching between the first heat exchange mode (parallel operation) and the second heat exchange mode (series operation) of the heat exchange assembly can be controlled by the two valves, which is relatively simple and convenient for the application of the heat exchange assembly. On the other hand, when using the first mode for heat exchange, the flow rate through the two flow paths through the first heat exchange tube group and the second heat exchange tube group can be controlled by the opening degree of the second valve.

[0016] In one implementation, the first valve includes a first connection port and a second connection port, which are respectively connected to a first manifold and a third cavity. The second valve includes a third connection port and a fourth connection port, which are respectively connected to a fourth cavity and a third cavity. When heat exchange is performed using the first heat exchange mode, the inlet of the first valve is connected to the first connection port, and the third connection port is connected to the fourth connection port. When heat exchange is performed using the second heat exchange mode, the inlet of the first valve is connected to the second connection port, and the second valve is closed.

[0017] In one implementation, the first heat exchange tube group includes a plurality of first heat exchange tubes spaced apart along a first direction, and the second heat exchange tube group includes a plurality of second heat exchange tubes spaced apart along the first direction, the first direction being the extension direction of the first manifold.

[0018] In this application, the heat exchange medium entering the first heat exchange tube group for heat exchange is diverted into multiple first heat exchange tubes, and the heat exchange medium entering the second heat exchange tube group for heat exchange is diverted into multiple second heat exchange tubes, thereby improving the heat exchange efficiency of the heat exchange components.

[0019] In one implementation, the first and second heat exchanger tube groups are arranged side-by-side along a second direction, which is perpendicular to the first and third directions. The third direction is the arrangement direction of the first and second manifolds. The heat exchange assembly has two rows of heat exchanger tubes arranged side-by-side. Multiple first and second heat exchanger tubes can be used to improve the heat exchange capacity of the heat exchange assembly. Furthermore, arranging the first and second heat exchanger tube groups side-by-side along the second direction can reduce the overall volume of the first and second heat exchanger tube groups, facilitating the miniaturization of the heat exchange assembly.

[0020] In one embodiment, the number of first heat exchange tubes is the same as the number of second heat exchange tubes. This facilitates the configuration of the heat exchange components.

[0021] In one implementation, the first manifold includes a first sub-pipe and a second sub-pipe arranged side-by-side along a second direction. The first and second sub-pipes respectively enclose a first cavity and a second cavity. A plurality of flow holes are provided between the first and second sub-pipes, spaced apart along a first direction. The first cavity and the second cavity are connected through the plurality of flow holes. The second manifold includes a third sub-pipe and a fourth sub-pipe arranged side-by-side along the second direction. The third and fourth sub-pipes respectively enclose a third cavity and a fourth cavity. The third cavity and the fourth cavity are isolated from each other by the walls of the third and fourth sub-pipes.

[0022] In this application, both the first and second manifolds include two parallel manifolds. The first sub-pipe, the first heat exchanger tube group, and the third sub-pipe constitute one row of heat exchangers. The second sub-pipe, the second heat exchanger tube group, and the fourth sub-pipe constitute another row of heat exchangers. The heat exchangers in the heat exchange assembly are double-row heat exchangers. In the first heat exchange mode, the parallel operation of the double-row flow path reduces the flow velocity of the heat exchange medium and the pressure drop of the heat exchange assembly. The resistance encountered by the heat exchange medium flowing within the heat exchange assembly is smaller, which is more conducive to the flow of the heat exchange medium within the heat exchange assembly. In the second heat exchange mode, a series double-row flow path can be used to increase the flow velocity of the heat exchange medium, resulting in a higher heat transfer coefficient and better heat exchange effect in the heat exchange assembly.

[0023] In one implementation, along the second direction, the first sub-tube, multiple first heat exchange tubes, and the third sub-tube are located on the leeward side, while the second sub-tube, multiple second heat exchange tubes, and the fourth sub-tube are located on the windward side. When heat exchange is performed using the first heat exchange mode, the total flow rate of the heat exchange medium passing through the multiple second heat exchange tubes is greater than the total flow rate of the heat exchange medium passing through the multiple first heat exchange tubes.

[0024] In one embodiment, when heat exchange is performed using the first heat exchange mode, the ratio of the flow rate in the plurality of second heat exchange tubes to the flow rate in the plurality of first heat exchange tubes is 3:1.

[0025] In this application, by controlling the flow rate of the heat exchange medium in the second heat exchange tube group to be greater than the flow rate of the heat exchange medium in the first heat exchange tube group, the subcooling of the second heat exchange tube group and the first heat exchange tube group are basically the same, thereby improving the performance of the heat exchange components.

[0026] In one implementation, the first heat exchange tube group includes a plurality of first heat exchange tubes spaced apart along a first direction, and the second heat exchange tube group includes a plurality of second heat exchange tubes spaced apart along the first direction, where the first direction is the extension direction of the first manifold. The first heat exchange tube group and the second heat exchange tube group are arranged side by side along the first direction.

[0027] In this embodiment, the heat exchange component is equipped with a single row of heat exchange tubes according to the actual heat exchange requirements. Multiple first and second heat exchange tubes can be set to improve the heat exchange capacity of the heat exchange component.

[0028] In one implementation, a first manifold fitting has a first partition plate intersecting a first direction. The first partition plate divides the inner cavity of the first manifold fitting into a first cavity and a second cavity arranged along the first direction. The first partition plate has an opening penetrating through it along the first direction, and the first cavity and the second cavity are connected through the opening. A second manifold fitting has a second partition plate intersecting the first direction. The second partition plate divides the inner cavity of the second manifold fitting into a third cavity and a fourth cavity arranged along the first direction and separated from each other.

[0029] In this application, both the first and second manifolds are single manifolds. The first and second manifolds, the first and second heat exchanger tube groups constitute a row of heat exchangers. The heat exchangers in the heat exchange assembly are single-row heat exchangers. Depending on the heat exchange requirements, in the first heat exchange mode, parallel flow paths can be used to reduce the flow velocity of the heat exchange medium and the pressure drop of the heat exchange assembly. The resistance encountered by the heat exchange medium flowing within the heat exchange assembly is smaller, which is more conducive to the flow of the heat exchange medium within the heat exchange assembly. In the second heat exchange mode, series flow paths can be used to increase the flow velocity of the heat exchange medium, resulting in a higher heat transfer coefficient and better heat exchange effect in the heat exchange assembly.

[0030] In one implementation, along the first direction, the distance between the first partition and the end of the first manifold furthest from the second cavity is greater than the distance between the first partition and the end of the first manifold furthest from the first cavity. Similarly, along the first direction, the distance between the second partition and the end of the second manifold furthest from the fourth cavity is greater than the distance between the second partition and the end of the second manifold furthest from the third cavity.

[0031] In one embodiment, the number of first heat exchange tubes is greater than the number of second heat exchange tubes.

[0032] In this application, the length of the first cavity along the first direction is greater than the length of the second cavity along the first direction. The length of the third cavity along the first direction is greater than the length of the fourth cavity along the first direction. The first and third cavities can be connected to a greater number of first heat exchange tubes. When using the second heat exchange mode, due to the larger number of first heat exchange tubes, when the heat exchange medium enters multiple first heat exchange tubes from the third cavity, the heat exchange medium is diverted into multiple first heat exchange tubes, reducing the flow rate of the heat exchange medium within the first heat exchange tubes and improving heat exchange efficiency.

[0033] Secondly, this application provides a heat exchange device, which includes a compressor, an evaporator, and the heat exchange components as described above. The outlet of the fourth chamber is connected to the inlet of the evaporator. When heat exchange is performed using a first heat exchange mode, the outlet of the evaporator is connected to the inlet of the valve assembly. When heat exchange is performed using a second heat exchange mode, the outlet of the evaporator is connected to the inlet of the compressor, and the outlet of the compressor is connected to the inlet of the valve assembly.

[0034] Thirdly, this application provides a heat exchange device, which includes a compressor, a condenser, and the heat exchange components as described above. The outlet of the condenser is connected to the inlet of the valve assembly. When heat exchange is performed using a first heat exchange mode, the outlet of the fourth chamber is connected to the inlet of the condenser. When heat exchange is performed using a second heat exchange mode, the outlet of the fourth chamber is connected to the inlet of the compressor, and the outlet of the compressor is connected to the inlet of the condenser.

[0056] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0057] In this document, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "multiple" means two or more.

[0058] Furthermore, in this article, directional terms such as "upper" and "lower" are defined relative to the orientation of the structure as shown in the attached drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the structure.

[0059] For ease of understanding, the English abbreviations and related technical terms used in the embodiments of this application will be explained and described below.

[0060] Parallelism: The parallelism defined in this application is not limited to absolute parallelism. This definition of parallelism can be understood as basic parallelism, allowing for situations where the parallelism is not absolute due to factors such as assembly tolerances, design tolerances, and structural flatness.

[0061] Perpendicularity: The perpendicularity defined in this application is not limited to an absolute perpendicular intersection (with an included angle of 90 degrees). It is permissible for non-absolute perpendicular intersections caused by factors such as assembly tolerances, design tolerances, and structural flatness. It is permissible for errors within a small angular range, such as an assembly error range of 80 to 100 degrees, which can all be understood as a perpendicular relationship.

[0062] Please see Figure 1 , Figure 1 This is a schematic diagram of a heat exchange system provided in one embodiment of this application.

[0063] The heat exchange device 1 provided in this application can be applied to a heat exchange system. The heat exchange system includes a housing chamber 2, a heat source 3, and the heat exchange device 1. The heat source 3 is located inside the housing chamber 2. The heat exchange device 1 has two inner cavities. One inner cavity of the heat exchange device 1 is connected to the housing chamber 2 (for ease of description, this inner cavity is defined as the inner circulation cavity 11), and the other inner cavity of the heat exchange device 1 is connected to the outside (for ease of description, this other inner cavity is defined as the outer circulation cavity 12). The heat exchange device 1 is used to dissipate heat from the heat source 3. The heat source 3 generates heat during operation. The housing chamber 2 is connected to the inner circulation cavity 11. The heat exchange device 1 drives the hot air in the housing chamber 2 into the inner circulation cavity 11. The hot air in the heat exchange device 1 undergoes heat exchange in the inner circulation cavity 11, cooling the hot air into cold air. The cold air is then returned to the housing chamber 2 to cool the heat source 3.

[0064] In one embodiment, an opening is made in the side wall of the receiving chamber 2, and the heat exchange device 1 is embedded in the opening and fixed to the side wall. This installation method can reduce the overall volume of the heat exchange system. The inner circulation chamber 11 has an indoor air inlet 13 and an indoor air outlet 14 (e.g., ...) on its side wall facing the heat source 3. Figure 1 (As shown). The indoor air inlet 13 and indoor air outlet 14 are respectively positioned facing the containment chamber 2. The containment chamber 2 achieves airflow circulation with the inner circulation chamber 11 through the indoor air inlet 13 and indoor air outlet 14. The outer circulation chamber 12 has an outdoor air inlet 15 and an outdoor air outlet 16 on its side wall away from the heat source 3. The outdoor air inlet 15 and outdoor air outlet 16 are positioned facing the outside and are connected to the outside to achieve airflow circulation between the outer circulation chamber 12 and the outside.

[0065] In one embodiment, the heat exchange system is a cabinet, a container, or a data center. When the heat exchange system is a cabinet, the housing 2 is the cabinet shell, and the heat exchange equipment 1 is installed on the side wall of the cabinet shell.

[0066] In one embodiment, the heat source is a server, a baseband processing unit, a lithium battery, or a power supply. The power supply refers to a switching power supply, used to rectify AC mains power into DC power to supply power to the electrical equipment. The lithium battery includes a single cell or a battery pack. Lithium batteries are used individually to supply power to the electrical equipment when the mains power fails. Lithium batteries are also used in photovoltaic energy storage scenarios, storing energy during the day and discharging it at night.

[0067] For example, the heat exchange system is a server rack. When the heat source 3 is a server, the server generates heat during operation. Sustained high temperatures will reduce the server's lifespan and may even cause the server to crash or be damaged. Therefore, the server rack needs to have good heat dissipation capabilities. Using the heat exchange device 1 of this application can improve the heat dissipation capabilities of the server rack, enabling the server to work normally and have a longer lifespan.

[0068] In some implementations, the heat exchange device 1 may be located outside the containment chamber 2 or inside the containment chamber 2, depending on the working scenario and heat exchange requirements of the heat exchange system.

[0069] For example, such as Figure 2a As shown, the heat exchanger 1 is located outside the housing 2. The inner circulation chamber 11 of the heat exchanger 1 is connected to the housing 2 through the first air duct 17, so that airflow circulation is achieved between the inner circulation chamber 11 and the housing 2. The outer circulation chamber 12 of the heat exchanger 1 has an opening that connects to the outside. When the heat exchanger 1 is located outside the housing 2, it can be used in smaller heat exchange systems, such as heat exchange systems that are cabinets or containers, where the housing 2 can be the outer shell of the cabinet or the shell of the container.

[0070] For example, such as Figure 2bAs shown, when the heat exchanger 1 is located inside the containment chamber 2, the inner circulation chamber 11 of the heat exchanger 1 has an opening communicating with the containment chamber 2, and the outer circulation chamber 12 of the heat exchanger 1 is connected to the outside through the second air duct 18, so that airflow can circulate between the outer circulation chamber 12 and the outside. When the heat exchanger 1 is located inside the containment chamber 2, it can be applied to larger heat exchange systems, such as a data center, where the containment chamber 2 can be the server room of the data center.

[0071] For example, the heat exchange system is a data center. Typically, a data center has multiple servers, which generate a large amount of heat during operation. Multiple heat exchange devices 1 can be set up as needed to jointly improve the heat dissipation effect of the data center and improve the data processing efficiency of the data center. When the heat exchange system is a server rack or container, multiple heat exchange devices 1 can also be set up as needed.

[0072] Please see Figure 3 , Figure 3 This is a schematic diagram of a heat exchange device 1 provided according to an embodiment of this application. The heat exchange component 10 provided in this application is applied to the heat exchange device 1 and used as a condensing device. The heat exchange device 1 includes an evaporator 20, a compressor 30, and the heat exchange component 10.

[0073] Evaporator 20 is located within the inner circulation chamber 11. Evaporator 20 exchanges heat with hot air. Evaporator 20 cools the hot air flowing to its surface and heats the heat exchange medium inside the evaporator 20. Compressor 30 compresses the heat exchange medium flowing to its surface. Heat exchange assembly 10 is located within the outer circulation chamber 12. Heat exchange assembly 10 exchanges heat with cold air. Cold air on the surface of heat exchange assembly 10 cools the heat exchange medium inside the heat exchange assembly 10 and heats the cold air flowing to its surface.

[0074] The outlet of heat exchange assembly 10 (i.e., outlet 2041 of the fourth chamber 204) is connected to the inlet of evaporator 20. Heat exchange assembly 10 supplies a lower-temperature heat exchange medium to evaporator 20. The outlet of evaporator 20 is connected to the inlet of heat exchange assembly 10 (i.e., inlet 105 of valve assembly 100). The lower-temperature heat exchange medium in evaporator 20 exchanges heat with the hot air in containment chamber 2, transforming into a higher-temperature heat exchange medium, which then flows into heat exchange assembly 10 for cooling. This cycle repeats to cool containment chamber 2, thereby cooling the heat source 3.

[0075] The heat exchanger 1 has a first heat exchange mode and a second heat exchange mode. When the cooling requirement inside the containment chamber 2 is not significant or the temperature outside the containment chamber 2 is lower than the temperature inside the containment chamber 2, the heat exchanger 1 can operate in the first heat exchange mode. In this case, the compressor 30 is turned off, and the outlet of the evaporator 20 is directly connected to the heat exchange assembly 10. That is, the heat exchange medium output from the evaporator 20 flows directly into the heat exchange assembly 10 without passing through the compressor 30.

[0076] When cooling is urgently needed inside the containment chamber 2 or the outside temperature is high, the heat exchanger 1 can operate in the second heat exchange mode. In this mode, the compressor 30 starts, and the outlet of the evaporator 20 is connected to the inlet of the heat exchange assembly 10 via the compressor 30. The heat exchange medium output from the evaporator 20 first flows into the compressor 30 for compression before flowing into the heat exchange assembly 10.

[0077] Please see Figure 4 , Figure 4 This is a schematic diagram of a heat exchange device 1 provided according to an embodiment of this application. The heat exchange component 10 provided in this application is applied to the heat exchange device 1 and used as an evaporation device. The heat exchange device 1 includes a condenser 40, a compressor 30, and the heat exchange component 10.

[0078] The condenser 40 is located within the external circulation chamber 12. The condenser 40 exchanges heat with the outside cold air. The cold air on the surface of the condenser 40 cools the heat exchange medium inside the condenser 40, and the higher-temperature heat exchange medium can be converted into a lower-temperature heat exchange medium after flowing through the condenser 40. The compressor 30 is used to compress the heat exchange medium flowing into the compressor 30. The heat exchange assembly 10 is located within the internal circulation chamber 11. The heat exchange assembly 10 exchanges heat with hot air. The heat exchange assembly 10 is used to cool the hot air flowing to its surface, and the hot air on its surface heats the heat exchange medium inside the heat exchange assembly 10.

[0079] The outlet of condenser 40 and the inlet of heat exchange assembly 10 (i.e., inlet 105 of valve assembly 100, see reference) Figure 5 The condenser 40 supplies a lower-temperature heat exchange medium to the heat exchange assembly 10. The outlet of the heat exchange assembly 10 (i.e., the outlet 2041 of the fourth chamber 204, in conjunction with reference) is connected. Figure 5 The heat exchanger 10 is connected to the inlet of the condenser 40. The heat exchanger 10, which has a lower temperature, exchanges heat with the hot air in the containment chamber 2 and becomes a heat exchanger with a higher temperature. Then, it flows into the condenser 40 for cooling. This cycle is repeated to cool the containment chamber 2 and thus cool the heat source 3.

[0080] The heat exchanger 1 has a first heat exchange mode and a second heat exchange mode. When the cooling requirement inside the containment chamber 2 is not significant or the temperature outside the containment chamber 2 is lower than the temperature inside the containment chamber 2, the heat exchanger 1 can operate in the first heat exchange mode. In this case, the compressor 30 is turned off, and the outlet of the heat exchange component 10 is directly connected to the condenser 40. That is, the heat exchange working fluid output by the heat exchange component 10 flows directly into the condenser 40 without passing through the compressor 30.

[0081] When cooling is urgently needed inside the containment chamber 2 or the outside temperature is high, the heat exchanger 1 can operate in the second heat exchange mode. In this mode, the compressor 30 starts, and the outlet of the heat exchange assembly 10 is connected to the inlet of the condenser 40 via the compressor 30. The heat exchange medium output from the heat exchange assembly 10 first flows into the compressor 30 for compression before flowing into the condenser 40.

[0082] In one embodiment, the heat exchange device 1 includes two heat exchange components 10 and a compressor 30. The two heat exchange components 10 are a first heat exchange component and a second heat exchange component, respectively. The first heat exchange component serves as an evaporator, and the second heat exchange component serves as a condenser. The outlet of the second heat exchange component is connected to the inlet of the first heat exchange component. In a first heat exchange mode, the compressor 30 is not started, and the outlet of the first heat exchange component is directly connected to the inlet of the second heat exchange component. In a second heat exchange mode, the compressor 30 is started, and the outlet of the first heat exchange component is connected to the inlet of the second heat exchange component through the compressor 30.

[0083] The heat exchange component 10 in this application is described in detail below.

[0084] Please see Figure 5 , Figure 6 and Figure 7 , Figure 5 This is a schematic diagram of a heat exchange assembly 10 provided in one embodiment of this application. Figure 6 This is a schematic diagram of the heat exchange component 10 provided in one embodiment of the present application in the first heat exchange mode. Figure 7 This is a schematic diagram of the heat exchange component 10 provided in one embodiment of this application when it is in the second heat exchange mode.

[0085] This application provides a heat exchange assembly 10, which includes a valve assembly 100, a first manifold 210, a second manifold 220, and a first heat exchange tube group 310 and a second heat exchange tube group 320 located between the first manifold 210 and the second manifold 220. The first manifold 210 has a first cavity 201 and a second cavity 202 that are connected to each other, and the second manifold 220 has a third cavity 203 and a fourth cavity 204 that are isolated from each other. The two ends of the first heat exchange tube group 310 are connected to the first cavity 201 and the third cavity 203, respectively, and the two ends of the second heat exchange tube group 320 are connected to the second cavity 202 and the fourth cavity 204, respectively. The valve assembly 100 is connected to the first manifold 210, the third cavity 203, and the fourth cavity 204, and is used to receive a heat exchange medium at a first temperature. The heat exchange assembly 10 includes a first heat exchange mode and a second heat exchange mode. When heat exchange is performed using the first heat exchange mode (e.g., Figure 6 As shown), the first manifold 210 is connected to the valve assembly 100 and receives the heat exchange medium at the first temperature through the valve assembly 100. The third chamber 203 and the fourth chamber 204 are connected through the valve assembly 100. When using the second heat exchange mode (e.g.) Figure 7 As shown), the third chamber 203 is connected to the valve assembly 100 and receives the heat exchange medium at the first temperature through the valve assembly 100; the heat exchange medium at the first temperature passes through the first heat exchange tube group 310 and the second heat exchange tube group 320 and then outputs the heat exchange medium at the second temperature from the fourth chamber 204.

[0086] The first manifold 210 contains a first cavity 201 and a second cavity 202 that are connected to each other, allowing the heat exchange medium to flow between the two cavities. In one embodiment, the first cavity 201 and the second cavity 202 are connected within the first manifold 210. For example, the first manifold 210 may contain a flow-through hole 213 or a pipe for connecting the first cavity 201 and the second cavity 202. In another embodiment, the first cavity 201 and the second cavity 202 are connected via an external pipe.

[0087] The second manifold 220 contains isolated third chambers 203 and fourth chambers 204. The isolation between the third chambers 203 and fourth chambers 204 means that the heat exchange medium within them cannot be connected within the second manifold 220. In other words, there is no internal channel between the third chambers 203 and fourth chambers 204, meaning they can only be connected via external piping. For example, when using the first heat exchange mode, the third chambers 203 and fourth chambers 204 are connected via an external valve assembly 100.

[0088] The first heat exchanger tube assembly 310 and the second heat exchanger tube assembly 320 have good thermal conductivity. When the heat exchange medium flows within the first heat exchanger tube assembly 310 and the second heat exchanger tube assembly 320, it can exchange heat with the outside environment, changing the heat exchange medium at a first temperature to a second temperature. The first heat exchanger tube assembly 310 connects the first cavity 201 and the third cavity 203, and the heat exchange medium can flow between the first cavity 201, the first heat exchanger tube assembly 310, and the third cavity 203. The second heat exchanger tube assembly 320 connects the second cavity 202 and the fourth cavity 204, and the heat exchange medium can flow between the second cavity 202, the second heat exchanger tube assembly 320, and the fourth cavity 204.

[0089] The valve assembly 100 includes one or more valves and has functions such as guiding, shutting off, and diverting flow. The valve assembly 100 is connected to the first manifold 210, the third cavity 203, and the fourth cavity 204. The valve assembly 100 can control the connection and shut-off between itself and these three chambers. In one embodiment, the valve assembly 100 is connected to each of these chambers via pipes.

[0090] The heat exchange assembly 10 includes two heat exchange modes. In one embodiment, the valve assembly 100 is connected to the first cavity 201 of the first manifold 210 (e.g., Figure 6 and Figure 7 (As shown). When heat exchange is performed using the first heat exchange mode, the heat exchange assembly 10 has two flow paths (as shown). Figure 6 (As shown). One flow path is as follows: the heat exchange medium at the first temperature sequentially passes through the valve assembly 100 and the first chamber 201 into the first heat exchange tube group 310. After exchanging heat with the outside environment in the first heat exchange tube group 310, the heat exchange medium at the first temperature is transformed into a heat exchange medium at the second temperature. The heat exchange medium at the second temperature sequentially flows through the third chamber 203, the valve assembly 100, and the fourth chamber 204, and flows out from the fourth chamber 204 to the outside of the heat exchange assembly 10.

[0091] Another flow path is (e.g.) Figure 6 (As shown): The heat exchange medium at the first temperature sequentially passes through the valve assembly 100, the first chamber 201, and the second chamber 202 into the second heat exchange tube assembly 320. After exchanging heat with the outside environment in the second heat exchange tube assembly 320, the heat exchange medium at the first temperature is transformed into a heat exchange medium at the second temperature. The heat exchange medium at the second temperature flows into the fourth chamber 204 and flows out from the fourth chamber 204 to the outside of the heat exchange assembly 10.

[0092] In the first heat exchange mode, the two flow paths are connected in parallel (e.g., Figure 6 (As shown). The flow direction of the heat exchange medium in the first heat exchange tube group 310 and the second heat exchange tube group 320 is the same, both flowing from the first manifold 210 to the second manifold 220. Both flow paths cover the length of one heat exchange tube group for heat exchange. When using the first heat exchange mode, the heat exchange medium in the heat exchange assembly 10 is divided into two parallel flow paths, reducing the flow velocity of the heat exchange medium and the pressure drop of the heat exchange assembly 10. The resistance encountered by the heat exchange medium when flowing in the heat exchange assembly 10 is smaller, which is more conducive to the flow of the heat exchange medium within the heat exchange assembly 10.

[0093] When using the second heat exchange mode for heat exchange (e.g.) Figure 7 As shown, the heat exchange assembly 10 has only one flow path. The heat exchange medium sequentially passes through the valve assembly 100, the third chamber 203, the first heat exchange tube group 310, the first chamber 201, the second chamber 202, the second heat exchange tube group 320, and the fourth chamber 204, and flows out from the fourth chamber 204. The heat exchange medium at the first temperature is transformed into a heat exchange medium at the second temperature after exchanging heat with the outside environment through the first heat exchange tube group 310 and the second heat exchange tube group 320.

[0094] In the second heat exchange mode, the flow paths within the heat exchange component 10 are in series (e.g., Figure 7 (As shown). The flow directions of the heat exchange medium in the first heat exchange tube group 310 and the second heat exchange tube group 320 are opposite. In the first heat exchange tube group 310, the heat exchange medium flows from the second manifold 220 to the first manifold 210, while in the second heat exchange tube group 320, the heat exchange medium flows from the first manifold 210 to the second manifold 220. When using the second heat exchange mode, the heat exchange assembly 10 has only one flow path, which results in a faster flow velocity of the heat exchange medium within the flow path, a higher heat transfer coefficient, and a better heat exchange effect.

[0095] In one embodiment, the valve assembly 100 may also be connected to the second cavity 202 of the first manifold 210. When heat exchange is performed using the first heat exchange mode, the heat exchange assembly 10 also has two flow paths. One flow path is as follows: the heat exchange medium sequentially passes through the valve assembly 100, the second cavity 202, the first cavity 201, the first heat exchange tube group 310, the third cavity 203, the valve assembly 100, and the fourth cavity 204, and flows out from the fourth cavity 204 to the outside of the heat exchange assembly 10. The other flow path is as follows: the heat exchange medium sequentially passes through the valve assembly 100, the second cavity 202, the second heat exchange tube group 320, and the fourth cavity 204, and flows out from the fourth cavity 204 to the outside of the heat exchange assembly 10. When heat exchange is performed using the second heat exchange mode, the heat exchange assembly 10 has only one flow path. The heat exchange medium passes sequentially through valve assembly 100, third chamber 203, first heat exchange tube group 310, first chamber 201, second chamber 202, second heat exchange tube group 320, and fourth chamber 204, and flows out from fourth chamber 204.

[0096] In one embodiment, the first heat exchange mode is also called the heat pipe mode. The first heat exchange mode is suitable for scenarios with low heat exchange efficiency. The second heat exchange mode is also called the compression refrigeration mode. The heat exchange efficiency is better in the second heat exchange mode. Generally, the first manifold 210, the second manifold 220, the first heat exchange tube group 310 and the second heat exchange tube group 320 constitute a heat exchanger, and the heat exchange assembly 10 includes a heat exchanger and a valve assembly 100.

[0097] In this application, valve assembly 100 is used to receive heat exchange medium at a first temperature, and the inlet 105 of valve assembly 100 is also the inlet of heat exchange assembly 10. Fourth chamber 204 outputs heat exchange medium at a second temperature, and the outlet 2041 of fourth chamber 204 is also the outlet of heat exchange assembly 10. In one embodiment, the inlet and outlet of heat exchange assembly 10 can also be interchanged, in which case the flow paths in the two modes flow in opposite directions.

[0098] The heat exchange component 10 provided in this application can switch between a first heat exchange mode and a second heat exchange mode. Selecting different heat exchange modes according to different heat exchange requirements can save energy. Switching between different flow paths in different heat exchange modes can effectively improve the heat exchange performance of the heat exchange component 10. In this application, on the one hand, a parallel flow path is used in the first heat exchange mode. Compared with the same series flow path as the second heat exchange mode, the parallel flow path in the first heat exchange mode reduces the flow velocity of the heat exchange medium and the pressure drop of the heat exchange component 10. The resistance encountered by the heat exchange medium when flowing in the heat exchange component 10 is smaller, which is more conducive to the flow of the heat exchange medium in the heat exchange component 10, thereby improving the performance of the heat exchange component 10. On the other hand, a series flow path is used in the second heat exchange mode. Compared with the same parallel flow path as the first heat exchange mode, the series flow path in the second heat exchange mode results in a faster flow velocity of the heat exchange medium in the heat exchange component 10, a higher heat transfer coefficient, and a better heat exchange effect.

[0099] In one implementation, the valve assembly 100 includes a first connection port 101, a second connection port 102, and a third connection port 103 (e.g., ...). Figure 6 and Figure 7 As shown, the first connection port 101, the second connection port 102, and the third connection port 103 are respectively connected to the first manifold 210, the third cavity 203, and the fourth cavity 204. When using the first heat exchange mode, the inlet 105 of the valve assembly 100 is connected to the first connection port 101, and the second connection port 102 and the third connection port 103 are connected. When using the second heat exchange mode, the inlet 105 of the valve assembly 100 is connected to the second connection port 102.

[0100] The valve assembly 100 is a single valve, comprising one inlet and three connection ports. The inlet of the valve assembly 100 receives a heat exchange medium at a first temperature, and this inlet also serves as the inlet of the heat exchange assembly 10. The first manifold 210, the third cavity 203, and the fourth cavity 204 can be connected via pipes to the first connection port 101, the second connection port 102, and the third connection port 103, respectively.

[0101] When using the first heat exchange mode for heat exchange (e.g.) Figure 6As shown, the inlet 105 of the valve assembly 100 is connected to the first connection port 101, meaning that the inlet 105 of the valve assembly 100 is connected to the first connection port 101 through the internal flow channel of the valve assembly 100. The first connection port 101 is the outlet of the valve assembly 100; the heat exchange medium enters the valve assembly 100 through the inlet 105 and can flow out of the valve assembly 100 through the first connection port 101. Additionally, the second connection port 102 and the third connection port 103 are connected. Since the third cavity 203 and the fourth cavity 204 are respectively connected to the second connection port 102 and the third connection port 103, the third cavity 203 and the fourth cavity 204 can be connected through the second connection port 102 and the third connection port 103. At this time, the inlet 105 of the valve assembly 100 is in a closed state with both the second connection port 102 and the third connection port 103; closed means no flow. Furthermore, the first connection port 101 is in a closed state with the second connection port 102 and the third connection port 103.

[0102] When using the first heat exchange mode for heat exchange (e.g.) Figure 6 As shown, one flow path in the heat exchange assembly 10 is as follows: the heat exchange medium enters the valve assembly 100 from the inlet 105, and passes through the first connection port 101, the first manifold 210, the first heat exchange tube group 310, the third cavity 203, the second connection port 102, the third connection port 103, and the fourth cavity 204 in sequence, and flows out from the fourth cavity 204 to the outside of the heat exchange assembly 10.

[0103] Another flow path is (e.g.) Figure 6 As shown): The heat exchange medium enters the valve assembly 100 from the inlet 105, and passes through the first connection port 101, the first manifold 210, the second heat exchange tube group 320, and the fourth cavity 204 in sequence, and flows out from the fourth cavity 204 to the outside of the heat exchange assembly 10.

[0104] When using the second heat exchange mode for heat exchange (e.g.) Figure 7 As shown, the inlet 105 of valve assembly 100 is connected to the second connection port 102, meaning that the inlet 105 of valve assembly 100 is connected to the second connection port 102 through the internal flow channel of valve assembly 100. The second connection port 102 is the outlet of valve assembly 100. After the heat exchange medium enters valve assembly 100 from inlet 105, it can flow out of valve assembly 100 through second connection port 102. At this time, the inlet 105 of valve assembly 100 is in a closed state with the first connection port 101 and the third connection port 103. Furthermore, the second connection port 102 and the third connection port 103 are not connected, and the third cavity 203 and the fourth cavity 204 cannot be connected through valve assembly 100.

[0105] When using the second heat exchange mode for heat exchange (e.g.) Figure 7As shown), the flow path in the heat exchange assembly 10 is as follows: the heat exchange medium enters the valve assembly 100 from the inlet 105, and passes through the second connection port 102, the third cavity 203, the first heat exchange tube group 310, the first manifold 210, the second heat exchange tube group 320, and the fourth cavity 204 in sequence, and flows out from the fourth cavity 204.

[0106] In this application, multiple interfaces are provided on the valve assembly 100, and only one valve is needed to control the flow path switching of the first heat exchange mode parallel operation and the second heat exchange mode series operation of the heat exchange assembly 10. The implementation method is relatively simple and facilitates the application of the heat exchange assembly 10.

[0107] In one embodiment, the valve assembly 100 is a five-way valve, and the valve assembly 100 further includes a fourth connection port 104. In one embodiment, the five-way valve has two flow channels, such as... Figure 6 and Figure 7 The first flow channel 111 and the second flow channel 112 are shown. When the heat exchange assembly 10 is using the first heat exchange mode, the first flow channel 111 connects the inlet 105 of the valve assembly 100 and the first connection port 101, and the second flow channel 112 connects the second connection port 102 and the third connection port 103. When the first heat exchange mode is changed to the second heat exchange mode, the valve core of the five-way valve is rotated to change the relative position of the first flow channel 111 and the second flow channel 112, so that the first flow channel 111 connects the inlet 105 of the valve assembly 100 and the second connection port 102, and the second flow channel 112 connects the third connection port 103 and the fourth connection port 104. At this time, since the third connection port 103 is in the closed state, there is no heat exchange medium flowing between the fourth cavity 204, the third connection port 103, and the fourth connection port 104. Continue rotating the valve core of the five-way valve so that the first flow channel 111 connects the second connection port 102 and the third connection port 103, and the second flow channel 112 connects the first connection port 101 and the fourth connection port 104. At this time, since the inlet 105 of the valve assembly 100 is in the closed state, the heat exchange medium cannot enter the heat exchange assembly 10 through the inlet 105 of the valve assembly 100, and there is no heat exchange medium flowing in the entire heat exchange assembly 10.

[0108] It is worth noting that, Figure 6 and Figure 7 The five-way valve shown is only one possible implementation. The five-way valve provided in this application includes, but is not limited to, the following: Figure 6 and Figure 7 As shown in the embodiment, the five-way valve can also achieve flow guidance and cut-off between the various connection ports through other embodiments.

[0109] In one embodiment, the valve assembly 100 can also be a four-way valve. The inlet 105, the first connection port 101, the second connection port 102, and the third connection port 103 of the valve assembly 100 are the four connection ports of the four-way valve. In different heat exchange modes, by changing the connection relationship between each connection port, the heat exchange assembly 10 can switch between different flow paths.

[0110] Please see Figure 8 , Figure 9 and Figure 10 , Figure 8 This is a schematic diagram of a heat exchange assembly 10 provided in one embodiment of this application. Figure 9 This is a schematic diagram of the heat exchange component 10 provided in one embodiment of the present application in the first heat exchange mode. Figure 10 This is a schematic diagram of the heat exchange component 10 provided in one embodiment of this application when it is in the second heat exchange mode.

[0111] In one implementation, the valve assembly 100 includes a first valve 121 and a second valve 122. The first valve 121 is connected to a first manifold 210 and a third cavity 203, and the second valve 122 is connected to the third cavity 203 and a fourth cavity 204. The first valve 121 is used to receive a heat exchange medium at a first temperature. When heat exchange is performed using a first heat exchange mode (e.g.) Figure 9 As shown), the first manifold 210 is connected to the first valve 121 and receives the heat exchange medium at the first temperature through the first valve 121. The third chamber 203 and the fourth chamber 204 are connected through the second valve 122. When using the second heat exchange mode (e.g.) Figure 10 As shown), the third cavity 203 is connected to the first valve 121 and receives the heat exchange medium at the first temperature through the first valve 121, while the second valve 122 is closed.

[0112] The valve assembly 100 includes two valves that control the heat exchange assembly 10 to switch between different flow paths. The first valve 121 controls the connection and disconnection between the first valve 121 and the first manifold 210, and between the first valve 121 and the third cavity 203. That is, the first valve 121 controls whether the heat exchange medium received by the first valve 121 flows to the first manifold 210 or to the third cavity 203. The second valve 122 controls the external connection and disconnection between the third cavity 203 and the fourth cavity 204. When the second valve 122 is open, the third cavity 203 and the fourth cavity 204 are connected through the second valve 122. When the second valve 122 is closed, the third cavity 203 and the fourth cavity 204 are not connected.

[0113] In one embodiment, the first valve 121 is a three-way valve, and the second valve 122 is a one-way valve or a two-way valve.

[0114] In one embodiment, the second valve 122 is an electronic valve. This facilitates the control of opening and closing of the second valve 122.

[0115] In one embodiment, the second valve 122 is a solenoid valve or an electronic expansion valve. For example, if the second valve 122 is an electronic expansion valve, when heat exchange is performed using the first heat exchange mode, the flow rate through the first heat exchange tube group 310 and the second heat exchange tube group 320 can be controlled by adjusting the opening of the electronic expansion valve, thereby improving the performance of the heat exchange assembly 10.

[0116] When using the first heat exchange mode for heat exchange (e.g.) Figure 9 As shown), one of the flow paths within the heat exchange assembly 10 is as follows: the heat exchange medium enters the heat exchange assembly 10 from the first valve 121, and passes sequentially through the first manifold 210, the first heat exchange tube group 310, the third cavity 203, the second valve 122, and the fourth cavity 204, and flows out from the fourth cavity 204 to the outside of the heat exchange assembly 10.

[0117] Another flow path is (e.g.) Figure 9 As shown): The heat exchange medium enters the heat exchange assembly 10 through the first valve 121, and passes through the first manifold 210, the second heat exchange tube group 320, and the fourth cavity 204 in sequence, and flows out of the fourth cavity 204 to the outside of the heat exchange assembly 10.

[0118] When heat exchange is performed using the first heat exchange mode, the first valve 121 and the third chamber 203 are in the closed state.

[0119] When using the second heat exchange mode for heat exchange (e.g.) Figure 10 As shown), the flow path inside the heat exchange assembly 10 is as follows: the heat exchange medium enters the heat exchange assembly 10 from the first valve 121, and passes through the third cavity 203, the first heat exchange tube group 310, the first manifold 210, the second heat exchange tube group 320, and the fourth cavity 204 in sequence, and flows out from the fourth cavity 204 to the outside of the heat exchange assembly 10.

[0120] When heat exchange is performed using the second heat exchange mode, the first valve 121 and the first manifold 210 are in the closed state.

[0121] In this application, the valve assembly 100 includes two valves. On the one hand, the flow path switching between the first heat exchange mode (parallel operation) and the second heat exchange mode (series operation) of the heat exchange assembly 10 can be controlled by the two valves, which is relatively simple and convenient for the application of the heat exchange assembly 10. On the other hand, when using the first mode for heat exchange, the flow rate through the two flow paths through the first heat exchange tube group 310 and the second heat exchange tube group 320 can be controlled by the opening degree of the second valve 122. For example, the temperature difference between the external fluid passing through the first heat exchanger tube group 310 and the heat exchange medium inside the first heat exchanger tube group 310 is small, while the temperature difference between the external fluid passing through the second heat exchanger tube group 320 and the heat exchange medium inside the second heat exchanger tube group 320 is large. At this time, the flow rate of the heat exchange medium passing through the second heat exchanger tube group 320 can be controlled by controlling the second valve 122 to make it greater than the flow rate of the heat exchange medium passing through the first heat exchanger tube group 310, so as to ensure that the subcooling in the second heat exchanger tube group 320 and the first heat exchanger tube group 310 is basically the same, thereby improving the performance of the heat exchange component 10.

[0122] In one implementation, the first valve 121 includes a first connection port 101 and a second connection port 102 (e.g., ...). Figure 9 and Figure 10 As shown), the first connection port 101 and the second connection port 102 are respectively connected to the first manifold 210 and the third cavity 203. The second valve 122 includes a third connection port 103 and a fourth connection port 104, which are respectively connected to the fourth cavity 204 and the third cavity 203.

[0123] In this configuration, the inlet 105 of the valve assembly 100 is the inlet of the first valve 121. When heat exchange is performed using the first heat exchange mode (e.g.) Figure 9 As shown, the inlet of the first valve 121 is connected to the first connection port 101, and the third connection port 103 is connected to the fourth connection port 104. The first connection port 101 is the outlet of the first valve 121, and the third connection port 103 and the fourth connection port 104 are the outlet and inlet of the second valve 122, respectively. At this time, there is no electrical connection between the first valve 121 and the second connection port 102, and the heat exchange medium cannot flow to the third cavity 203 through the first valve 121.

[0124] When using the first heat exchange mode for heat exchange (e.g.) Figure 9 As shown), one flow path in the heat exchange assembly 10 is as follows: the heat exchange medium enters the heat exchange assembly 10 from the inlet 105 of the first valve 121, and passes through the first connection port 101, the first manifold 210, the first heat exchange tube group 310, the third cavity 203, the fourth connection port 104, the third connection port 103, the fourth cavity 204 in sequence, and flows out from the fourth cavity 204 to the outside of the heat exchange assembly 10.

[0125] Another flow path is (e.g.) Figure 9As shown): The heat exchange medium enters the heat exchange assembly 10 from the inlet 105 of the first valve 121, and passes through the first connection port 101, the first manifold 210, the second heat exchange tube group 320, and the fourth cavity 204 in sequence, and flows out from the fourth cavity 204 to the outside of the heat exchange assembly 10.

[0126] When using the second heat exchange mode for heat exchange (e.g.) Figure 10 As shown, the inlet 105 of the first valve 121 is connected to the second connection port 102. The second connection port 102 is the outlet of the first valve 121. At this time, there is no electrical connection between the inlet 105 of the first valve 121 and the first connection port 101, and the heat exchange medium cannot flow to the first cavity 201 through the first valve 121. Furthermore, there is no electrical connection between the third connection port 103 and the fourth connection port 104, and the third cavity 203 and the fourth cavity 204 cannot be connected through the second valve 122.

[0127] When using the second heat exchange mode for heat exchange (e.g.) Figure 10 As shown), the flow path in the heat exchange assembly 10 is as follows: the heat exchange medium enters the heat exchange assembly 10 from the inlet 105 of the first valve 121, and passes through the second connection port 102, the third cavity 203, the first heat exchange tube group 310, the first manifold 210, the second heat exchange tube group 320, and the fourth cavity 204 in sequence, and flows out from the fourth cavity 204.

[0128] In this application, multiple interfaces are provided on the first valve 121 and the second valve 122 to facilitate the connection between the valve assembly 100 and the manifold. The flow path switching of the heat exchange assembly 10 between the first heat exchange mode and the second heat exchange mode can be controlled through two valves, which is relatively simple to implement and facilitates the application of the heat exchange assembly 10.

[0129] Please see Figure 11 , Figure 11 This is a schematic diagram of a heat exchange assembly 10 provided in one embodiment of this application. In one implementation, the valve assembly 100 includes a first valve 121, a second valve 122, and a third valve 123. The first valve 121 and the second valve 122 are respectively connected to a first manifold 210 and a third cavity 203, and the third valve 123 is connected to the third cavity 203 and a fourth cavity 204. When heat exchange is performed using a first heat exchange mode, the first manifold 210 is connected to the first valve 121 and receives the heat exchange medium at a first temperature through the first valve 121. The third cavity 203 and the fourth cavity 204 are connected through the third valve 123, and the second valve 122 is closed. When heat exchange is performed using a second heat exchange mode, the third cavity 203 is connected to the second valve 122 and receives the heat exchange medium at a first temperature through the second valve 122, and the first valve 121 and the third valve 123 are closed.

[0130] The valve assembly 100 includes three valves, which control the heat exchange assembly 10 to switch different flow paths. The first valve 121, the second valve 122, and the third valve 123 respectively control the connection and disconnection between the first valve 121 and the first manifold 210, between the second valve 122 and the third cavity 203, and between the third cavity 203 and the fourth cavity 204.

[0131] When heat exchange is performed using the first heat exchange mode, the first valve 121 is used to receive the heat exchange medium at the first temperature, and the inlet of the first valve 121 is the inlet 105 of the valve assembly 100. One of the flow paths within the heat exchange assembly 10 is as follows: the heat exchange medium enters the heat exchange assembly 10 through the first valve 121, and sequentially passes through the first manifold 210, the first heat exchange tube group 310, the third cavity 203, the third valve 123, and the fourth cavity 204, and flows out from the fourth cavity 204 to the outside of the heat exchange assembly 10.

[0132] Another flow path is as follows: the heat exchange medium enters the heat exchange assembly 10 from the first valve 121, and passes through the first manifold 210, the second heat exchange tube group 320, and the fourth cavity 204 in sequence, and flows out from the fourth cavity 204 to the outside of the heat exchange assembly 10.

[0133] When heat exchange is performed using the second heat exchange mode, the second valve 122 is used to receive the heat exchange medium at the first temperature, and the inlet of the second valve 122 is the inlet 105 of the valve assembly 100. The flow path within the heat exchange assembly 10 is as follows: the heat exchange medium enters the heat exchange assembly 10 through the second valve 122, and sequentially passes through the third cavity 203, the first heat exchange tube group 310, the first manifold 210, the second heat exchange tube group 320, and the fourth cavity 204, and flows out from the fourth cavity 204 to the outside of the heat exchange assembly 10.

[0134] Please see Figure 12 and Figure 13 , Figure 12 A perspective view of a portion of the heat exchange assembly 10 provided in one embodiment of this application. Figure 13 An exploded view of a portion of the heat exchange assembly 10 provided in one embodiment of this application.

[0135] In one implementation, the first heat exchange tube group 310 includes a plurality of first heat exchange tubes 311 arranged at intervals along a first direction X, and the second heat exchange tube group 320 includes a plurality of second heat exchange tubes 321 arranged at intervals along a first direction X, wherein the first direction X is the extension direction of the first manifold 210.

[0136] The extension direction of the first manifold 210 is approximately parallel to the extension direction of the second manifold 220, and the first direction X is also the extension direction of the second manifold 220. Each first heat exchange tube 311 connects to the first cavity 201 and the third cavity 203 at both ends along the third direction Z. Each second heat exchange tube 321 connects to the second cavity 202 and the fourth cavity 204 at both ends along the third direction Z. The third direction Z is the arrangement direction of the first manifold 210 and the second manifold 220.

[0137] In this application, the heat exchange medium entering the first heat exchange tube group 310 for heat exchange is diverted into multiple first heat exchange tubes 311, and the heat exchange medium entering the second heat exchange tube group 320 for heat exchange is diverted into multiple second heat exchange tubes 321, thereby improving the heat exchange efficiency of the heat exchange component 10.

[0138] In one embodiment, the first heat exchange tube 311 is a flat tube. Both ends of the flat tube are inserted into the first cavity 201 and the third cavity 203, respectively. The flat tube has multiple microchannels (not shown in the figure) that connect the first cavity 201 and the third cavity 203. The flat tube can be fixed and sealed to the first manifold 210 and the second manifold 220 by welding.

[0139] In one embodiment, the second heat exchange tube assembly 320 is a flat tube. Both ends of the flat tube are inserted into the second cavity 202 and the fourth cavity 204, respectively. The flat tube has multiple microchannels (not shown in the figure) that connect the second cavity 202 and the fourth cavity 204. The flat tube can be fixed and sealed to the first manifold 210 and the second manifold 220 by welding.

[0140] In one implementation, the first heat exchanger tube group 310 and the second heat exchanger tube group 320 are arranged side by side along the second direction Y (e.g., Figure 12 and Figure 13 As shown, the second direction Y is perpendicular to the first direction X and the third direction Z, where the third direction Z is the arrangement direction of the first manifold 210 and the second manifold 220. Multiple first heat exchange tubes 311 and multiple second heat exchange tubes 321 are arranged side-by-side along the second direction Y. The first cavity 201 and the second cavity 202, as well as the third cavity 203 and the fourth cavity 204, are all arranged along the second direction Y.

[0141] In this application, the heat exchange assembly 10 is provided with two rows of heat exchange tubes arranged side by side. Multiple first heat exchange tubes 311 and second heat exchange tubes 321 can be provided to improve the heat exchange capacity of the heat exchange assembly 10. Furthermore, the side-by-side arrangement of the first heat exchange tube group 310 and the second heat exchange tube group 320 along the second direction Y can reduce the overall volume of the first heat exchange tube group 310 and the second heat exchange tube group 320, which facilitates the miniaturization of the heat exchange assembly 10.

[0142] In one embodiment, the number of first heat exchange tubes 311 is the same as the number of second heat exchange tubes 321. This facilitates the configuration of the heat exchange assembly 10.

[0143] In one implementation, the first manifold 210 includes a first sub-pipe 211 and a second sub-pipe 212 arranged side-by-side along the second direction Y (e.g., ...). Figure 12 As shown), the first sub-tube 211 and the second sub-tube 212 respectively enclose and form the first cavity 201 and the second cavity 202 (see also). Figure 5 The first sub-pipe 211 and the second sub-pipe 212 are provided with a plurality of flow holes 213 spaced apart along the first direction X, and the first cavity 201 and the second cavity 202 are connected through the plurality of flow holes 213. The second manifold 220 includes a third sub-pipe 221 and a fourth sub-pipe 222 arranged side by side along the second direction Y. The third sub-pipe 221 and the fourth sub-pipe 222 respectively form a third cavity 203 and a fourth cavity 204, which are isolated from each other by the pipe walls of the third sub-pipe 221 and the fourth sub-pipe 222.

[0144] In this application, the first manifold 210 includes two parallel manifolds. The second manifold 220 also includes two parallel manifolds. The first sub-pipe 211, the first heat exchange tube group 310, and the third sub-pipe 221 constitute one row of heat exchangers. The second sub-pipe 212, the second heat exchange tube group 320, and the fourth sub-pipe 222 constitute another row of heat exchangers. The heat exchangers in the heat exchange assembly 10 are double-row heat exchangers. In the first heat exchange mode, the double-row parallel flow path reduces the flow velocity of the heat exchange medium and the pressure drop of the heat exchange assembly 10. The resistance encountered by the heat exchange medium when flowing in the heat exchange assembly 10 is smaller, which is more conducive to the flow of the heat exchange medium in the heat exchange assembly 10. In the second heat exchange mode, a double-row series flow path can be used to increase the flow velocity of the heat exchange medium. The heat exchange assembly 10 has a high heat transfer coefficient and a better heat exchange effect.

[0145] In one implementation, along the second direction Y, the first sub-tube 211, multiple first heat exchange tubes 311 and the third sub-tube 221 are located on the leeward side, and the second sub-tube 212, multiple second heat exchange tubes 321 and the fourth sub-tube 222 are located on the windward side. When heat exchange is performed using the first heat exchange mode, the total flow rate of the heat exchange medium passing through the multiple second heat exchange tubes 321 is greater than the total flow rate of the heat exchange medium passing through the multiple first heat exchange tubes 311.

[0146] Generally, external fluid flows through the first heat exchange tube group 310 and the second heat exchange tube group 320, exchanging heat with them. The fluid includes liquids and gases. To improve heat exchange efficiency, the flow direction of the external fluid is generally perpendicular to the larger plane in the heat exchanger. In this application, multiple first heat exchange tubes 311 and multiple second heat exchange tubes 321 are all arranged along a first direction X. The plane formed by the first direction X and the third direction Z is the larger plane of the heat exchanger, and the flow direction of the external fluid is the second direction Y.

[0147] The windward side refers to the side where the external fluid first passes through the heat exchanger assembly 10 along the second direction Y, i.e., the side where the external fluid flows in. The leeward side refers to the side where the external fluid passes through the heat exchanger assembly 10 later along the second direction Y, i.e., the side where the external fluid flows out. The external fluid passes through the second heat exchanger tube group 320 and the first heat exchanger tube group 310 successively. Because the second heat exchanger tube group 320 is located on the windward side and the first heat exchanger tube group 310 is located on the leeward side, the temperature difference between the external fluid and the heat exchange medium inside the second heat exchanger tube group 320 is relatively large when the external fluid flows through it. The temperature difference between the external fluid and the heat exchange medium inside the first heat exchanger tube group 310 is relatively small when the external fluid flows through it.

[0148] In this application, by controlling the flow rate of the heat exchange medium in the second heat exchange tube group 320 to be greater than the flow rate of the heat exchange medium in the first heat exchange tube group 310, the subcooling of the second heat exchange tube group 320 and the first heat exchange tube group 310 is basically the same, thereby improving the performance of the heat exchange component 10.

[0149] In one embodiment, parameters such as the diameter and number of flow holes 213, the diameters of the first sub-tube 211 and the second sub-tube 212, and the diameters of the second heat exchange tube 321 and the first heat exchange tube 311 can be limited so that the total flow rate of the heat exchange medium passing through multiple second heat exchange tubes 321 is greater than the total flow rate of the heat exchange medium passing through multiple first heat exchange tubes 311.

[0150] In one embodiment, the diameter of the first sub-tube 211 and the second sub-tube 212 is 36 mm, and the diameter of the flow hole 213 is 4 mm.

[0151] In one embodiment, the number of flow holes 213 between the first sub-tube 211 and the second sub-tube 212 is 10, and the number of first heat exchange tubes 311 is 39.

[0152] In this application, by designing the diameter and number of flow holes 213, the ratio of the flow rate in the multiple second heat exchange tubes 321 to the flow rate in the multiple first heat exchange tubes 311 is within a suitable range when heat exchange is performed using the first heat exchange mode, thereby ensuring that the subcooling of the second heat exchange tube group 320 and the first heat exchange tube group 310 is basically the same, and improving the performance of the heat exchange component 10.

[0153] In one embodiment, when heat exchange is performed using the first heat exchange mode, the ratio of the flow rate in the multiple second heat exchange tubes 321 to the flow rate in the multiple first heat exchange tubes 311 is (2-4):1. At this flow rate ratio, the subcooling of the second heat exchange tube group 320 and the first heat exchange tube group 310 can be kept basically the same, so as to better improve the performance of the heat exchange assembly 10.

[0154] In one embodiment, when heat exchange is performed using the first heat exchange mode, the ratio of the flow rate in the plurality of second heat exchange tubes 321 to the flow rate in the plurality of first heat exchange tubes 311 is 3:1.

[0155] Please see Figure 14 and Figure 15 , Figure 14 This is a schematic diagram of the heat exchange component 10 provided in one embodiment of the present application in the first heat exchange mode. Figure 15 This is a schematic diagram of the heat exchange component 10 provided in one embodiment of this application when it is in the second heat exchange mode.

[0156] In one implementation, the first heat exchange tube group 310 includes multiple first heat exchange tubes 311 spaced apart along a first direction X, and the second heat exchange tube group 320 includes multiple second heat exchange tubes 321 spaced apart along the first direction X, where the first direction X is the extension direction of the first manifold 210. The first heat exchange tube group 310 and the second heat exchange tube group 320 are arranged side by side along the first direction X. The heat exchange tubes are spaced apart along the first direction X. The first cavity 201 and the second cavity 202, as well as the third cavity 203 and the fourth cavity 204, are all arranged along the first direction X.

[0157] In one embodiment, a plurality of first heat exchange tubes 311 and a plurality of second heat exchange tubes 321 are arranged at equal intervals along a first direction X.

[0158] In this embodiment, according to the actual heat exchange requirements, the heat exchange component 10 is provided with a single row of heat exchange tubes. Multiple first heat exchange tubes 311 and second heat exchange tubes 321 can be provided to improve the heat exchange capacity of the heat exchange component 10.

[0159] In one implementation, the first manifold 210 is provided with a first partition 214 (e.g., Figure 14 and Figure 15As shown, the first partition 214 intersects the first direction X, dividing the inner cavity of the first manifold 210 into a first cavity 201 and a second cavity 202 arranged along the first direction X. The first partition 214 has an opening 215 extending through it along the first direction X, and the first cavity 201 and the second cavity 202 are connected through the opening 215. The second manifold 220 has a second partition 224 intersecting the first direction X, dividing the inner cavity of the second manifold 220 into a third cavity 203 and a fourth cavity 204 arranged along the first direction X and separated from each other.

[0160] The first manifold 210 is a single pipe. The plane of the first partition 214 intersects the first direction X. The edge of the first partition 214 is fixedly connected to the inner wall of the first manifold 210. One or more openings 215 may be provided on the first partition 214. The second manifold 220 is also a single pipe. The plane of the second partition 224 intersects the first direction X. The edge of the second partition 224 is fixedly connected to the inner wall of the first manifold 210. The second partition 224 divides the inner cavity of the second manifold 220 into two non-communicating cavities.

[0161] In this application, the first manifold 210, the second manifold 220, the first heat exchange tube group 310, and the second heat exchange tube group 320 constitute a row of heat exchangers. The heat exchangers in the heat exchange assembly 10 are single-row heat exchangers. Depending on the heat exchange requirements, in the first heat exchange mode, a parallel flow path can be used to reduce the flow velocity of the heat exchange medium and the pressure drop of the heat exchange assembly 10. The resistance encountered by the heat exchange medium flowing within the heat exchange assembly 10 is smaller, which is more conducive to the flow of the heat exchange medium within the heat exchange assembly 10. In the second heat exchange mode, a series flow path can be used to increase the flow velocity of the heat exchange medium, resulting in a higher heat transfer coefficient and better heat exchange effect in the heat exchange assembly 10.

[0162] In one embodiment, the first manifold 210 and the second manifold 220 provided in this application can be modified from existing manifolds.

[0163] In one implementation, along the first direction X, the distance between the first partition 214 and the end of the first manifold 210 furthest from the second cavity 202 is greater than the distance between the first partition 214 and the end of the first manifold 210 furthest from the first cavity 201 (e.g., ...). Figure 14 and Figure 15 (As shown). Along the first direction X, the distance between the second partition 224 and the end of the second manifold 220 away from the fourth cavity 204 is greater than the distance between the second partition 224 and the end of the second manifold 220 away from the third cavity 203.

[0164] The first manifold 210 includes a first end 216 and a second end 217 along a first direction X. A first cavity 201 is located between the first end 216 and the first partition 214. A second cavity 202 is located between the second end 217 and the first partition 214. The first end 216 is the end of the first manifold 210 away from the second cavity 202. The second end 217 is the end of the first manifold 210 away from the first cavity 201.

[0165] The second manifold 220 includes a third end 226 and a fourth end 227 along the first direction X. A third cavity 203 is located between the third end 226 and the second partition 224. A fourth cavity 204 is located between the fourth end 227 and the second partition 224. The third end 226 is the end of the second manifold 220 away from the fourth cavity 204. The fourth end 227 is the end of the second manifold 220 away from the third cavity 203, adjacent to the second partition 224.

[0166] In this application, the first partition 214 is positioned near the second end 217, such that the length of the first cavity 201 along the first direction X is greater than the length of the second cavity 202 along the first direction X. The second partition 224 is positioned near the fourth end 227, such that the length of the third cavity 203 along the first direction X is greater than the length of the fourth cavity 204 along the first direction X. The first cavity 201 and the third cavity 203 can be connected to a greater number of first heat exchange tubes 311. When heat exchange is performed using the second heat exchange mode, due to the large number of first heat exchange tubes 311, when the heat exchange medium enters multiple first heat exchange tubes 311 from the third cavity 203, the heat exchange medium is diverted into multiple first heat exchange tubes 311, reducing the flow rate of the heat exchange medium in the first heat exchange tubes 311 and improving the heat exchange efficiency.

[0167] In one embodiment, the number of first heat exchange tubes 311 is greater than the number of second heat exchange tubes 321.

[0168] In one embodiment, the first partition 214 is located at the middle position of the first manifold 210 along the first direction X (e.g., Figure 16 and Figure 17 As shown, the second partition 224 is located at the middle position of the second manifold 220 along the first direction X. Along the first direction X, the distance between the first partition 214 and the first end 216 and the second end 217 is equal, and the distance between the second partition 224 and the third end 226 and the fourth end 227 is equal.
