[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0050] To dissipate heat from power modules, related technologies often employ copper pin-type heat sinks and finned structures. This utilizes natural convection to change the density of the air, allowing the heat generated by the power module to be carried away by natural convection through air layers at different temperatures. However, this heat dissipation method has low heat exchange efficiency and poor heat transfer effect.

[0051] To solve the above-mentioned technical problems, this application provides a heat exchange device 1, which is used to exchange heat for the component 2 to be heat exchanged. Please refer to [link to relevant documentation]. Figure 1 and Figure 2 .

[0052] In some embodiments, please combine Figure 3 The heat exchange device includes a first jet element 11 and a second jet element 13, with the heat exchange element 2 disposed between the first jet element 11 and the second jet element 13.

[0053] In the heat exchange device of this application embodiment, a first jetting element 11 and a second jetting element 13 are provided, and the heat exchange element 2 to be exchanged is disposed between the first jetting element 11 and the second jetting element 13. The liquid forms a jet by passing through the first jetting element 11 and the second jetting element 13, and the heat exchange efficiency and heat exchange effect are improved by the jetting of the heat exchange element 2 disposed between the first jetting element 11 and the second jetting element 13.

[0054] Furthermore, due to the provision of the first jetting element 11 and the second jetting element 13, more jets can be generated when the liquid passes through, resulting in a better heat exchange effect of the heat exchange device 1, which can fully exchange heat for the heat exchange element 2.

[0055] In some examples, the first jetting element 11 can be plate-shaped or rectangular, and can have multiple small holes or slits. When liquid passes through these holes or slits, it is ejected at high speed, forming a jet. Thus, after the liquid passes through the first jetting element 11, a jet can be formed. In some examples, the second jetting element 13 can be plate-shaped or rectangular; it can also have multiple small holes or slits. When liquid passes through these holes or slits, it is ejected at high speed, forming a jet. Thus, after the liquid passes through the second jetting element 13, a jet can be formed.

[0056] It is readily understood that, through the technical solution of this application, the liquid or coolant, after passing through the first jetting element 11 and / or the second jetting element 13, forms a jet, which can be sprayed at high speed onto the target surface to exchange heat for the heat exchange component 2. When the jet impacts a point on the target surface, heat and mass transfer occur between the jet and the target surface, thereby generating a thinner boundary layer, reducing the thermal resistance and enhancing heat transfer.

[0057] In some examples, the liquid or coolant can be a mixture of water and ethylene glycol or a fluorinated liquid, etc.

[0058] It should be noted that the formation of the jet is due to the liquid being forced through a small-area outlet under high pressure, which causes a sharp increase in the liquid velocity. This is based on the continuity equation and Bernoulli's principle. According to the continuity equation, in the case of incompressible fluid flow, the flow rate remains constant. Therefore, if the flow cross-section decreases, such as through the orifices on the first jet element 11 or the second jet element 13, the flow velocity will increase accordingly. When the liquid passes through the orifice or slit, it undergoes a contraction process near the orifice or slit, causing the liquid velocity to increase significantly. Once the liquid leaves the orifice or slit, it enters a relatively low-pressure environment and continues to move forward due to inertia, forming a jet.

[0059] In some examples, please combine Figure 8 , Figure 8 This is a schematic diagram of one embodiment of the first jet element 11. The first jet element 11 and the second jet element 13 have the same structure, therefore the structure of the second jet element 13 can also be referred to. Figure 8 Both the first jetting element 11 and the second jetting element 13 are plate-shaped, and both have jetting holes 12. The cross-sectional shape of the jetting holes 12 can be circular, so that when the liquid or coolant passes through, it becomes a jet, forming a jet. The thickness of the first jetting element 11 and the second jetting element 13 can be selected according to the required jetting pressure. The shape, diameter, position, and distribution of the jetting holes on the first jetting element 11 and the second jetting element 13 can be adjusted according to the actual heat dissipation requirements of the heat exchange component. This application embodiment does not limit this. Please refer to... Figure 10 , Figure 10 This is a schematic diagram of another embodiment of the first jet element 11, which differs from... Figure 8 The specific structure of the first jet component is shown in the diagram. Figure 10 In this process, the shape and density of the jet orifice 12 of the first jetting component 11 were changed. Please refer to... Figure 11 , Figure 12 as well as Figure 13 , Figure 11 yes Figure 10 Top view of the first jet component 11; Figure 12 yes Figure 10 A cross-sectional view of the first jetting element 11. Figure 13 yes Figure 10 An enlarged schematic diagram of part D of the heat exchange component shows that along the arrangement direction of the first jet element 11 and the second jet element 13, the diameter of the jet hole 12 first remains unchanged and then gradually decreases, thereby improving the heat exchange effect.

[0060] In some examples, the heat exchange component 2 can be an IGBT. In some examples, the heat exchange component 2 can also be a power module, such as a packaged device integrating multiple power components such as MOSFETs and IGBTs. In some examples, the heat exchange component 2 can be a chip, etc.

[0061] In some embodiments, the heat exchange component 2 is a power element integrating an IGBT, and the heat exchange component 2 of this application is used to dissipate heat and cool the power element integrating an IGBT.

[0062] In some embodiments, please combine Figure 3 The second jet element 13 and the first jet element 11 can form a heat exchange space 20, which is used to install the heat exchange element 2 to be heat exchanged.

[0063] In this embodiment, heat exchange device 1 is used to exchange heat for heat exchange component 2. By setting a first jet component 11 and a second jet component 13, and installing heat exchange component 2 in heat exchange space 20, liquid will generate jets as it passes through the first jet component 11 and the second jet component 13, thereby exchanging heat for heat exchange component 2 in heat exchange space 20 and improving the heat exchange effect.

[0064] In these implementations, the second jet element 13 and the first jet element 11 form a heat exchange space 20, which is used to install the heat exchange element 2 to be heat exchanged. In this way, heat exchange can be performed on the heat exchange element 2 within the heat exchange space 20 through the second jet element 13 and the first jet element 11.

[0065] In some examples, the first jet element 11 is used to form a jet to dissipate heat from the heat exchange element 2 within the heat exchange space.

[0066] In some examples, the second jet element 13 is used to form a jet to dissipate heat from the heat exchanger within the heat exchange space 20.

[0067] In some examples, the first jet element 11 is used to form a jet to dissipate heat from the component to be heat-exchanged within the heat exchange space. Simultaneously, the second jet element 13 is used to form a jet to dissipate heat from the component to be heat-exchanged within the heat exchange space.

[0068] In some embodiments, please combine Figure 3 The first jetting element 11 and / or the second jetting element 13 are used to emit jets toward the heat exchanger 2, thereby enabling heat dissipation from the heat exchanger 2.

[0069] In some examples, the first jetting element 11 may be used to emit a jet toward the heat exchanger 2.

[0070] In some examples, a second jetting element 13 may be used to emit a jet toward the heat exchanger 2.

[0071] In some examples, the first jetting element 11 may be used to emit a jet toward the heat exchanger 2. At the same time, the second jetting element 13 may be used to emit a jet toward the heat exchanger 2.

[0072] In some examples, please combine Figure 3 The first jetting element 11 and the second jetting element 13 can be used to emit jets toward the opposite sides of the heat exchanger 2, thereby exchanging heat between the opposite sides of the heat exchanger 2. This increases the heat exchange area, allowing both sides of the heat exchanger 2 to undergo sufficient heat exchange, resulting in higher heat exchange efficiency and better heat exchange effect.

[0073] In some embodiments, please combine Figure 3 The heat exchange device 1 also includes a first housing 50, which has an installation cavity 51, and the first jet element 11 and the second jet element 13 are installed in the installation cavity 51.

[0074] In these embodiments, the heat exchange device 1 further includes a first housing 50, which has a mounting cavity 51 for mounting the first jet member 11 and the second jet member 13, thereby protecting the first jet member 11 and the second jet member 13 disposed in the first housing 50.

[0075] The first jetting component 11 can be connected to the first housing 50 by welding, snap-fitting, screwing, or other means, so that the first jetting component 11 can be installed in the mounting cavity 51 of the first housing 50. The second jetting component 13 can be connected to the first housing 50 by welding, snap-fitting, screwing, or other means, so that the first jetting component 11 can be installed in the mounting cavity 51 of the first housing 50.

[0076] In some examples, the first jet element 11 can be arranged parallel to and spaced apart from the second jet element 13, so that the space between the first jet element 11 and the second jet element 13 is the heat exchange space 20. The heat exchange element 2 to be installed is installed in the heat exchange space 20, that is, the heat exchange element 2 to be installed is installed between the first jet element 11 and the second jet element 13.

[0077] In some embodiments, please combine Figure 2 as well as Figure 3 The first housing 50 is provided with a liquid inlet 53, which communicates with the mounting cavity 51; and / or,

[0078] The first housing 50 is provided with multiple liquid inlets 53; and / or,

[0079] The first housing 50 is provided with a liquid outlet 55, which communicates with the mounting cavity 51; and / or,

[0080] The first housing 50 is provided with a liquid outlet 55, and there are multiple liquid outlets 55.

[0081] In some examples, the first housing 50 is provided with a liquid inlet 53, which is connected to the mounting cavity 51.

[0082] In some examples, the first housing 50 is provided with a liquid inlet 53, and the number of liquid inlets 53 is multiple.

[0083] In these examples, multiple liquid inlets 53 can be provided to improve liquid inlet efficiency, allowing a larger volume of liquid to enter in a shorter time, thereby increasing heat exchange efficiency. The opening degree of each of the multiple liquid inlets 53 can be varied; for example, valves can be installed at the liquid inlets 53 to adjust the opening degree. Coolant can be introduced through the liquid inlets to dissipate heat and cool the heat exchange components. The opening degree of the liquid inlets can be changed or several inlets can be closed as needed, thus adjusting the liquid inlet efficiency.

[0084] In some examples, the first housing 50 is provided with a liquid outlet 55, which is in communication with the mounting cavity 51.

[0085] In some examples, the first housing 50 is provided with a liquid outlet 55, and the number of liquid outlets 55 is multiple.

[0086] In these examples, multiple liquid outlets 55 can be set to improve liquid discharge efficiency, enabling a larger volume of liquid to flow out in a shorter time, thereby increasing heat exchange efficiency. The opening degree of each of the multiple liquid outlets 55 can be changed; for example, valves can be installed at the liquid outlets 55 to adjust the opening degree. The opening degree of the liquid outlets can be changed or several outlets can be closed as needed, thus adjusting the liquid discharge efficiency.

[0087] In some examples, the first housing 50 is provided with a liquid inlet 53 and a liquid outlet 55, which are respectively connected to the mounting cavity 51.

[0088] In these embodiments, by providing an inlet 53 and an outlet 55 in the first housing 50, liquid can be continuously fed in and out during heat exchange, resulting in better cooling effect.

[0089] In some examples, liquid enters the mounting cavity 51 of the first housing 50 through the inlet 53 and passes through the first jetting element 11 and the second jetting element 13 located within the mounting cavity 51. After passing through the first jetting element 11, the liquid forms a jet, primarily impacting the side of the heat exchanger 2 facing the first jetting element 11, thus performing heat exchange for the heat exchanger 2. After passing through the second jetting element 13, the liquid forms a jet, primarily impacting the side of the heat exchanger 2 facing the second jetting element 13, thus performing heat exchange for the heat exchanger 2. In this way, the first jetting element 11 and the second jetting element 13 emit jets towards the opposite sides of the heat exchanger 2, achieving heat exchange between the opposite sides of the heat exchanger 2.

[0090] In some embodiments, the first housing 50 includes a first sidewall 56 and a second sidewall 57 disposed opposite to each other. The first sidewall 56 is located on the side of the first jet member 11 away from the second jet member 13, and the second sidewall 57 is located on the side of the second jet member 13 away from the first jet member 11. The first sidewall 56 has at least one liquid inlet 53, and the second sidewall 57 has at least one liquid inlet 53.

[0091] In these embodiments, by providing liquid inlets 53 on both the first sidewall 56 and the second sidewall 57, liquid can be introduced from both the first sidewall 56 and the second sidewall 57 simultaneously. This allows the first jet member 11 near the first sidewall 56 and the second jet member 13 near the second sidewall 57 to be introduced into the liquid more quickly, thereby enabling the first jet member 11 and the second jet member 13 to generate jets more quickly and improving the heat exchange rate of the heat exchange member 2 to be exchanged.

[0092] In some examples, please combine Figure 1 as well as Figure 3 The first housing 50 may be provided with a first coolant inlet passage 501, a second coolant inlet passage 502, a third coolant inlet passage 503, a fourth coolant inlet passage 504, a fifth coolant inlet passage 505, a sixth coolant inlet passage 506, a first coolant outlet passage 507, and a second coolant outlet passage 508. The first coolant inlet passage 501, the third coolant inlet passage 503, and the fifth coolant inlet passage 505 may be connected to the first sidewall 56 of the first housing 50, specifically by welding. The second coolant inlet passage 502, the fourth coolant inlet passage 504, and the sixth coolant inlet passage 506 may be connected to the second sidewall 57 of the first housing 50, specifically by welding. The first coolant inlet passage 501, the second coolant inlet passage 502, the third coolant inlet passage 503, the fourth coolant inlet passage 504, the fifth coolant inlet passage 505, the sixth coolant inlet passage 506, the first coolant outlet passage 507, and the second coolant outlet passage 508 can all be pipe structures, and the material can be aluminum alloy. Each of the first coolant inlet passage 501, the second coolant inlet passage 502, the third coolant inlet passage 503, the fourth coolant inlet passage 504, the fifth coolant inlet passage 505, and the sixth coolant inlet passage 506 has a liquid inlet 53, resulting in a total of six liquid inlets 53. Each of the first coolant outlet passage 507 and the second coolant outlet passage 508 has a liquid outlet 55, resulting in a total of two liquid outlets 55.

[0093] Please combine Figure 1 as well as Figure 2The first housing 50 may further include a third sidewall 58 and a fourth sidewall 59 disposed opposite to each other, both of which are connected between the first sidewall 56 and the second sidewall 57. The third sidewall 58 may be connected to a first coolant outlet passage 507, specifically by welding. The fourth sidewall 59 may be connected to a second coolant outlet passage 508, specifically by welding.

[0094] The first housing 50 can be made of aluminum alloy. Liquid can enter the heat exchange device through the first coolant inlet passage 501, the second coolant inlet passage 502, the third coolant inlet passage 503, the fourth coolant inlet passage 504, the fifth coolant inlet passage 505, and the sixth coolant inlet passage 506. After exchanging heat with the heat exchange component 70, the liquid can flow out of the heat exchange device through the first coolant outlet passage 507 and the second coolant outlet passage 508.

[0095] In some embodiments, please combine Figure 3 The heat exchange device 1 also includes a heat exchange component 70, which is disposed in the heat exchange space 20 and is used to install the heat exchange component 2 to be heat exchanged.

[0096] In these embodiments, the heat exchange component 2 is mounted on the heat exchange assembly 70, so that the heat exchange assembly 70 can exchange heat with the heat exchange component 2, and the jet can exchange heat with the heat exchange assembly 70. Compared with the method of directly spraying the jet onto the heat exchange component 2, the impact on the heat exchange component 2 can be reduced.

[0097] The heat exchange component 70 is made of a thermally conductive material, which enables the heat generated by the heat exchange component 2 to be exchanged with the jet.

[0098] In some examples, please combine Figure 3 The heat exchange device 1 includes a first housing 50, which has a liquid inlet 53 and a liquid outlet 55. A first jetting element 11 and a second jetting element 13 are installed in the mounting cavity 51 of the first housing 50. Liquid can flow into the heat exchange device from the liquid inlet 53 and flow out of the heat exchange device from the liquid outlet 55. The first jetting element 11 and the second jetting element 13 can be welded to the cavity wall of the mounting cavity 51 of the first housing 50, respectively. Liquid forms a jet through the first jetting element 11, which cools the heat exchange assembly 70, thereby dissipating heat for the heat exchange component 2; liquid forms a jet through the second jetting element 13, which cools the heat exchange assembly 70, thereby dissipating heat for the heat exchange component 2. The heat exchange assembly 70 can be welded to the cavity wall of the mounting cavity 51 of the first housing 50 and is located between the first jetting element 11 and the second jetting element 13. Since the heat exchange component 2 is disposed in the first heat exchange chamber 71 of the heat exchange assembly 70, the heat generated by the heat exchange component 2 can be exchanged with the jet through the heat exchange assembly 70, thereby cooling the heat exchange component 2.

[0099] In some embodiments, the heat exchange assembly 70 includes a second housing 73, and a first heat exchange cavity 71 is provided in the second housing 73. The first heat exchange cavity 71 is used to install the heat exchange component 2.

[0100] In these embodiments, the heat exchange component 2 is installed inside the second housing 73, which can better protect the heat exchange component 2.

[0101] Please combine Figure 3 as well as Figure 9 In some embodiments, the heat exchange assembly 70 further includes a heat exchange element 75, which is connected to the second housing 73.

[0102] In these embodiments, the presence of the heat exchanger 75 on the second housing 73 effectively increases the heat exchange area of ​​the second housing 73, thereby improving heat exchange efficiency. For example, when a jet is emitted into the second housing 73, the presence of the heat exchanger 75 effectively increases the heat exchange area between the jet and the second housing 73. When no jet is emitted into the second housing 73, the presence of the heat exchanger 75 effectively increases the heat exchange area between the air and the second housing 73.

[0103] It is easy to understand that the heat exchanger 75 is made of a thermally conductive material. The heat generated by the heat exchanger 2 can be conducted to the second housing 73 and the heat exchanger 75, and then further dissipated, thereby relieving heat on the heat exchanger 2.

[0104] The heat exchanger 75 may be provided on only one side of the second housing 73, or the heat exchanger 75 may be provided on multiple sides of the second housing 73.

[0105] The heat exchanger 75 can be a finned structure, a needle-like structure, etc.

[0106] The height of the heat exchanger 75, or the height of the heat exchanger 75 protruding from the second housing 73, can be determined according to the heat exchange requirements. However, the heat exchanger 75 needs to be spaced apart from the first jet element 11 and the second jet element 13 respectively.

[0107] The heat exchanger 75 can be made of pure copper plated with nickel, stainless steel, ceramic, or cermet, etc.

[0108] In some examples, the heat exchanger 75 cross-sectional shape can be triangular, rectangular, or other shapes.

[0109] In some examples, the heat exchanger 75 may be provided on only one side of the second housing 73, or it may be provided on multiple sides of the second housing 73.

[0110] Please combine Figure 3 as well as Figure 9 In some embodiments, there are multiple heat exchange elements 75, which are spaced apart in the second housing 73.

[0111] In these embodiments, multiple heat exchangers 75 are configured, and the multiple heat exchangers 75 are spaced apart in the second housing 73. This further increases the heat exchange area of ​​the heat exchangers 75 and improves the heat exchange efficiency.

[0112] In some examples, the heat exchanger 75 may have multiple sets of fin structures or multiple sets of needle-like structures, etc.

[0113] In some examples, the heat exchanger 75 is connected to the second housing 73, which is disposed in the heat exchange space 20. The heat exchange space 20 is formed by the second jetting element 13 and the first jetting element 11. When the first jetting element 11 and the second jetting element 13 are located on opposite sides of the heat exchange assembly 70, the second housing 73 and the heat exchanger 75 are both located between the first jetting element 11 and the second jetting element 13. The heat exchanger 75 can be connected to the side of the second housing 73 closest to the first jetting element 11. The heat exchanger 75 can be a needle-like structure. Thus, since the first jetting element 11 and the second jetting element 13 are disposed on opposite sides of the heat exchange assembly 70, when the liquid passes through the first jetting element 11 and the second jetting element 13, a jet is formed, allowing the liquid to be sprayed onto the heat exchanger 75 at a higher speed, enhancing heat exchange and improving the heat exchange effect.

[0114] Please combine Figure 4 In some of these examples and embodiments, a second heat exchange cavity 77 is also provided in the second housing 73. The second heat exchange cavity 77 is spaced apart from the first heat exchange cavity 71 and is used to contain the phase change material.

[0115] In these embodiments, a phase change material is provided to absorb the heat generated by the heat exchange element 2 in the first heat exchange chamber 71.

[0116] In some examples, the second heat exchange chamber 77 is spaced apart from the first heat exchange chamber 71. The phase change material in the second heat exchange chamber 77 does not enter the first heat exchange chamber 71, but heat transfer can occur between the second heat exchange chamber 77 and the first heat exchange chamber 71. Thus, the heat generated by the heat exchange component 2 in the first heat exchange chamber 71 can be transferred to the second heat exchange chamber 77. After absorbing heat, the phase change material in the second heat exchange chamber 77 undergoes a phase change. For example, the phase change material in the second heat exchange chamber 77 can be solid and become liquid after absorbing heat; or, the phase change material in the second heat exchange chamber 77 can be solid and become gaseous after absorbing heat; or, the phase change material in the second heat exchange chamber 77 can be liquid and become gaseous after absorbing heat.

[0117] Please combine Figure 3 as well as Figure 4In some examples, the second heat exchange chamber 77 can be located at the end of the second housing 73 opposite to the heat exchanger 75. The end of the second housing 73 near the first jet member 11 is connected to the heat exchanger 75, and the second heat exchange chamber 77 is located at the end of the second housing 73 near the first jet member 11. Thus, since the first jet member 11 and the second jet member 13 are arranged on opposite sides of the heat exchange assembly 70, when the liquid passes through the first jet member 11 and the second jet member 13, a jet is formed, allowing the liquid to be sprayed at a high speed at opposite ends of the second housing 73. The liquid can exchange heat with the heat exchanger 75 and with the phase change material in the second heat exchange chamber 77, thereby enhancing heat exchange and improving the heat exchange effect.

[0118] In this embodiment, a second heat exchange chamber 77 is added. This allows for heat dissipation of the heat exchange component 2 at low operating temperatures using only phase change heat exchange. At this time, no liquid or coolant enters the first housing 50, and the liquid inlet 53 can be closed.

[0119] In some examples, phase change materials can be nitrates or carbonates, etc.

[0120] Please combine Figure 6 as well as Figure 7 In some embodiments, the heat exchange assembly 70 includes an elastic element 72, and the second housing 73 is provided with an opening 730 for connecting the second heat exchange chamber 77 and the heat exchange space 20. When the phase change material 79 undergoes a phase change, the elastic element 72 extends from the opening 730 to the heat exchange space 20 located outside the second housing 73.

[0121] In these embodiments, when the phase change material 79 undergoes a phase change, the elastic element 72 extends from the opening 730 into the heat exchange space 20 located outside the second housing 73, thereby increasing the heat exchange area. Please refer to... Figure 6 as well as Figure 7 , Figure 6 as well as Figure 7 In the middle, the elastic element 72 extends from the opening 730 into the heat exchange space 20 located outside the second housing 73. Please refer to... Figure 3 as well as Figure 4 , Figure 3 as well as Figure 4 In this process, the elastic element 72 does not extend from the opening 730 to the heat exchange space 20 located outside the second housing 73. The elastic element 72 can be located inside the opening 730 or inside the second heat exchange cavity 77.

[0122] Specifically, when the phase change material 79 absorbs heat and undergoes a phase change, its volume increases. This increased volume compresses the elastic element, causing the elastic element 72 to extend from the opening 730 into the heat exchange space 20 located outside the second housing 73. (Please refer to...) Figure 6as well as Figure 7 , Figure 6 as well as Figure 7 In the middle, the elastic element 72 extends from the opening 730 to the heat exchange space 20 located outside the second housing 73.

[0123] The elastic element 72 can be made of a composite material of zinc oxide and rubber or other elastic thermally conductive materials.

[0124] In some examples, by setting the elastic element 72, when the heat exchange component 2 reaches a certain temperature, the phase change material in the second heat exchange chamber 77 vaporizes. Furthermore, as the temperature in the second heat exchange chamber 77 increases, the phase change material continues to absorb heat, increasing the gas volume and thus exerting pressure on the elastic element 72. This causes the elastic element 72 to extend from the opening 730 into the heat exchange space 20 located outside the second housing 73, thereby increasing the heat exchange area and enhancing the heat exchange effect.

[0125] In some examples, the elastic element 72 may be connected to the second housing 73 and cover the opening 730. The elastic element 72 may be bonded to the second housing 73. Alternatively, a connector may be used to press the elastic element 72 against the wall of the second housing 73. The elastic element 72 may be an elastic thin film structure, and the connector may be a pressure ring, which connects to the second housing 73 to mount the thin film structure located between the pressure ring and the second housing 73 onto the second housing 73. The connection between the pressure ring and the second housing 73 may be by screwing, welding, etc. Alternatively, the connector may be a sealing ring, which connects to the second housing 73 to mount the thin film structure located between the sealing ring and the second housing 73 onto the second housing 73. The connection between the sealing ring and the second housing 73 may be by screwing, welding, etc. When the heat absorption volume of the phase change material increases, it can exert pressure on the thin film structure, causing the thin film structure to extend from the opening 730 to the heat exchange space 20 located outside the second housing 73, thereby increasing the heat exchange area and enhancing the heat exchange effect.

[0126] The elastic element 72 is connected to the second housing 73 and covers the opening 730. The elastic element 72 can seal the opening 730, so that the phase change material 79 cannot enter the outside of the second heat exchange chamber 77 from the opening 730.

[0127] In some examples, the heat exchanger 75 is connected to the upper end of the second housing 73, the second heat exchange cavity 77 is opened at the lower end of the second housing 73, and the lower end of the second housing 73 is provided with an opening 730 for connecting the second heat exchange cavity 77 and the heat exchange space 20. In some examples, the opening 730 may be opened on the lower side of the cavity wall of the second heat exchange cavity 77.

[0128] Please combine Figure 14 as well as Figure 15In some examples, the cavity wall of the second heat exchange chamber 77 on the side away from the heat exchanger 75 can be provided with an opening 730 with a large distance, and the elastic element 72 is filled into the opening 730. In some examples, the entire side of the second heat exchange chamber 77 away from the heat exchanger 75 can be provided with elastic elements 72, so that after the phase change material undergoes a phase change, the elastic element 72 expands as a whole to dissipate heat.

[0129] Please combine Figure 4 , Figure 6 as well as Figure 7 In some embodiments, the heat exchange device 1 further includes a temperature sensor 81, which is installed in the first heat exchange chamber 71.

[0130] In these embodiments, the temperature inside the first heat exchange chamber 71 is measured by the temperature sensor 81, which can reflect the temperature of the heat exchange component 2 inside the first heat exchange chamber 71. Thus, by setting the temperature sensor 81, the temperature distribution of the heat exchange component 2 can be monitored in real time.

[0131] When the temperature of the temperature sensor 81 changes, the liquid flow rate at the liquid inlet 53 of the first housing 50 can be changed. For example, the liquid flow rate at the liquid inlet 53 can be adjusted by changing the valve opening of the liquid inlet 53, or the number of liquid inlets 53 can be changed by closing or opening the liquid inlet 53, thereby changing the liquid flow rate. This enables effective heat exchange of the heat exchange component 2 and allows for dynamic adjustment of the temperature and pressure balance and stability of the heat exchange device 1.

[0132] In some examples, when the temperature of the temperature sensor 81 rises, the liquid flow rate of the liquid inlet 53 of the first housing 50 can be increased. For example, the liquid flow rate of the liquid inlet 53 can be increased by increasing the valve opening of the liquid inlet 53, or by opening more liquid inlets 53 to increase the number of liquid inlets 53, thereby increasing the liquid flow rate of the liquid inlet 53.

[0133] In some examples, when the temperature of the temperature sensor 81 decreases, the liquid flow rate of the liquid inlet 53 of the first housing 50 can be reduced. For example, the liquid flow rate of the liquid inlet 53 can be reduced by decreasing the valve opening of the liquid inlet 53, or the number of liquid inlets 53 can be reduced by closing more liquid inlets 53.

[0134] Please combine Figure 5 In some embodiments, the heat exchange device 1 further includes a pressure sensor 83, which is installed in the second heat exchange chamber 77.

[0135] In these embodiments, the pressure within the second heat exchange chamber 77 is measured by a pressure sensor 83, thereby reflecting the degree of heat absorption by the phase change material 79 within the second heat exchange chamber 77. In some examples, the phase change material is a liquid; when the phase change material absorbs heat, it can change phase to gas, and its volume will increase relative to that of the liquid. Furthermore, as the gas absorbs heat, its volume will further increase. Thus, by setting the pressure sensor 83, the pressure of the phase change material within the second heat exchange chamber 77 after absorbing heat can be monitored in real time.

[0136] In some examples, the second housing 73 has a first heat exchange chamber 71, and the heat exchange component 2 to be heat exchanged is installed inside the second housing 73. The heat exchange component 2 can be an IGBT, and there can be multiple heat exchange components 2. A temperature sensor 81 is also installed inside the first heat exchange chamber 71, and there can be multiple temperature sensors. For example, there can be three heat exchange components 2 and three temperature sensors 81, with one temperature sensor 81 corresponding to one heat exchange component 2. This allows different temperature sensors 81 to detect the temperature of different heat exchange components 2, and multiple temperature sensors 81 can monitor the temperature distribution of different heat exchange components 2, thereby enabling more targeted heat exchange of the heat exchange components 2 and improving heat exchange efficiency.

[0137] In some examples, when the temperature of the heat exchange component 2 is high, it will transfer heat outwards. This heat can be transferred to the second heat exchange chamber 77. The phase change material in the second heat exchange chamber 77 absorbs heat and undergoes a phase change until it completely transforms into a gaseous state. As the temperature continues to rise, the gaseous phase change material can continue to expand, causing the elastic element 72 to expand. The elastic element 72 can extend from the opening 730 into the heat exchange space 20 located outside the second housing 73, increasing the contact area with the heat exchange medium in the heat exchange space 20. For example, when a liquid is introduced, the heat exchange medium can be a liquid. When no liquid is introduced, the heat exchange medium can be a gas, thereby increasing the heat exchange area.

[0138] In some examples, the heat exchange component 2 generates heat, which is then conducted to the second housing 73, the heat exchange component 75, and the second heat exchange chamber 77. The phase change material in the second heat exchange chamber 77 continuously absorbs heat until it is completely vaporized. The completely vaporized phase change material can continue to absorb heat, which causes the elastic component 72 to expand. The expanded elastic component 72 is equivalent to increasing its surface area, which in turn increases the heat exchange area and enhances the heat exchange effect.

[0139] In some examples, when the pressure sensor 83 reaches the set value P1 and the temperature sensor 81 reaches the set temperature value T1, the liquid inlet 53 can be opened to allow liquid to enter. To ensure sufficient heat exchange for the heat exchange component 2, the liquid inlets 53 located on both sides of the heat exchange component 2 can be opened. Specifically, this can be achieved by opening the first coolant inlet passage 501 and the second coolant inlet passage 502, allowing liquid to enter the inlets of both passages and enabling heat exchange for the heat exchange component 2.

[0140] In some examples, if the temperature sensor 81 reading continues to rise, the flow rate of the incoming coolant can be changed by adjusting the opening of the inlet of the first coolant inlet path 501 and the inlet of the second coolant inlet path 502. When the temperature sensor 81 reading continues to rise and reaches the set temperature value T2 (T2 is greater than T1), more inlets can be opened, such as the third coolant inlet path 503 and the fourth coolant inlet path 504. If the temperature sensor 81 reading continues to rise, the opening of the inlet of the third coolant inlet path 503 and the fourth coolant inlet path 504 can be adjusted to change the flow rate of the incoming coolant. When the temperature sensor 81 reading continues to rise and reaches the set temperature value T3 (T3 is greater than T2), more inlets can be opened, such as the fifth coolant inlet path 505 and the sixth coolant inlet path 506.

[0141] In some examples, if the heat exchanger 2 begins to cool, when the reading of temperature sensor 81 decreases from temperature value T3 to temperature value T4, the flow rate of the incoming liquid can be adjusted by regulating the opening of the liquid inlet, or several liquid inlets can be closed. When the reading of temperature sensor 81 continues to decrease and falls below the set temperature value T5 (T5 can be less than T2, T5 can be less than T4), the opening of the liquid inlet of the third coolant inlet path 503 and the liquid inlet of the fourth coolant inlet path 504 can be adjusted or the liquid inlets can be closed. When the reading of temperature sensor 81 continues to decrease and falls below the set temperature value T6 (T6 can be less than T1, T6 can be less than T5), the opening of the liquid inlet of the fifth coolant inlet path 505 and the liquid inlet of the sixth coolant inlet path 506 can be adjusted or the liquid inlets can be closed. When the monitored values ​​of each temperature sensor 81 are lower than their respective set temperature values, and the pressure monitored value of pressure sensor 83 is lower than the pressure set value P2, all liquid inlets can be closed.

[0142] In some examples, after the pressure sensor 83 reaches the pressure setpoint P2, the liquid inlet flow rate can be reduced. Specifically, this can be achieved by changing the opening degree of the liquid inlet or by changing the number of liquid inlets that can receive liquid. This prevents excessive liquid flow rate from causing excessive pressure, which could potentially damage the heat exchange component 70, and also reduces the energy consumption due to liquid flow.

[0143] In this embodiment, the cooling liquid passes through the first jet member 11 and the second jet member 13 to form a jet, which reaches the heat exchange assembly 70 and passes through the second housing 73, the heat exchange member 75, and the elastic member 72 of the heat exchange assembly 70. Thus, the cooling liquid jet can exchange heat with the heat exchange member 75 and the expanded elastic member 72, thereby cooling the heat exchange member 2. The cooling liquid after heat exchange can flow out of the heat exchange device from the first coolant outlet passage 507 and the second coolant outlet passage 508.
