[0057] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0058] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0059] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0060] The following is for reference. Figures 1-13 The heat exchange module 10 according to an embodiment of the present utility model is described.

[0061] The heat exchange module 10 according to an embodiment of the present invention includes: a heat exchange plate assembly 1 and a conductive element 2.

[0062] Specifically, refer to Figures 1-13 The heat exchange plate assembly 1 has a heat exchange channel 16, and the conductive element 2 is disposed within the heat exchange channel 16. It should be noted that a refrigerant flows within the heat exchange channel 16, and the refrigerant is an insulating refrigerant, thereby preventing the conductive element 2 from short-circuiting or causing other dangers. The conductive element 2 can be a copper busbar or the like extending along the length of the heat exchange channel 16.

[0063] It is understandable that by placing the conductive element 2 within the heat exchange channel 16, the refrigerant can directly cool the conductive element 2, thereby increasing heat exchange efficiency. Furthermore, for the same conductive element 2 size, when the conductive element 2 is immersed in the refrigerant, the cooled area is larger compared to when the conductive element 2 is stacked with the heat exchange plate assembly 1. Therefore, while reducing the size of the conductive element 2, the cooling capacity of the heat exchange plate assembly 1 for the conductive element 2 is still maintained, thus reducing costs.

[0064] In addition, since the conductive element 2 is located inside the heat exchange channel 16, and the heat exchange plate assembly 1 is generally made of metal, the heat exchange plate assembly 1 can be formed as a shielding and isolation structure for the conductive element 2, thereby eliminating the need for additional shielding and isolation structures to isolate and shield the nearby circuit board, further reducing costs.

[0065] According to the embodiment of the present invention, the heat exchange module 10 has a heat exchange channel 16 in the heat exchange plate assembly 1, and the conductive element 2 is disposed in the heat exchange channel 16. The refrigerant can directly cool the conductive element 2, thereby increasing the heat exchange efficiency. At the same time, while reducing the size of the conductive element 2, the cooling capacity of the heat exchange plate assembly 1 for the conductive element 2 is still guaranteed, thereby reducing the cost.

[0066] In some embodiments of this utility model, such as Figures 1-3 As shown, the heat exchange module 10 also includes: a connection structure 3, a connecting hole 11 communicating with the heat exchange channel 16, one end of the connection structure 3 passing through the connecting hole 11 and electrically connected to the conductive component 2, and the other end electrically connected to the electrical equipment. It should be noted that the electrical equipment can be a power supply component or an electrical element requiring power (such as a front-end electrical control distribution unit, compressor, PTC (Positive Temperature Coefficient semiconductor material or component), etc.).

[0067] It is understandable that by passing through the connecting hole 11 and electrically connecting to the conductive element 2, the connecting structure 3 can be used to input current to the conductive element 2, and also to transmit the current on the conductive element 2 to the electrical components. The connecting structure 3 passes through the connecting hole 11 and is connected to the conductive element 2, thereby realizing the circuit connection between the conductive element 2 and the power supply and the electrical components, so that the electrical components can work normally.

[0068] In some embodiments of this utility model, such as Figures 1-8 As shown, the connecting structure 3 is at least partially disposed in the heat exchange channel 16. It can be understood that the conductive element 2 is spaced apart from the inner wall of the heat exchange channel 16 with the connecting hole 11, and the connecting structure 3 is at least partially disposed in the heat exchange channel 16, so that the refrigerant can also directly cool or heat the connecting structure 3, thereby improving the heat exchange efficiency of the connecting structure 3.

[0069] In some embodiments of this utility model, such as Figures 1-8 As shown, the connecting hole 11 is located on one side of the heat exchange plate assembly 1 in the thickness direction. It can be understood that the heat exchange plate assembly 1 has more arrangement space on one side in the thickness direction. By placing the connecting hole 11 on one side of the heat exchange plate assembly 1 in the thickness direction, the space on one side of the heat exchange plate assembly 1 in the thickness direction can be better utilized for installation, making installation convenient and optimizing the space arrangement.

[0070] In some embodiments of this utility model, such as Figures 1-8 As shown, the heat exchange module 10 also includes fasteners, which are used to fix the external conductor between the connection structure 3 and the electrical equipment. Thus, the fasteners can both ensure electrical conductivity between the external conductor and the connection structure 3, and guarantee a reliable and secure connection between the external conductor and the connection structure 3.

[0071] In some embodiments of this utility model, such as Figures 1-8 As shown, the connecting structure 3 has a connecting groove, and fasteners are set in the connecting groove to press the external conductor between the connecting structure 3 and the electrical equipment. This ensures the reliability of the connection between the connecting structure 3 and the external conductor, thereby improving conductivity reliability and stabilizing the circuit.

[0072] In some embodiments of this utility model, such as Figures 1-8 As shown, the bottom of the fastener is spaced apart from the bottom wall of the connecting groove. This avoids installation interference when the fastener is installed to the bottom of the connecting groove, ensuring smooth installation.

[0073] In some embodiments of this utility model, such as Figures 1-8 As shown, the connection structure 3 includes: a connector 30, one end of which passes through the connecting hole 11 and is electrically connected to the conductive element 2, and the other end of which is used to be electrically connected to the electrical equipment; wherein, the heat exchange module 10 also includes: a fastener, which is used to fix the external conductor between the connector 30 and the electrical equipment.

[0074] Thus, by setting the connector 30, the current from the power supply can be input to the conductive component 2, and it is also used to transmit the current on the conductive component 2 to the electrical components, thereby realizing the circuit connection between the conductive component 2, the power supply component, and the electrical components, so that the electrical components can work normally.

[0075] In some embodiments of this utility model, such as Figures 1-6As shown, the connector 30 includes an input pole 31, one end of which is used for electrical connection with a power source. The input pole 31 includes a first input pole 311 and a second input pole 312. The connecting hole 11 includes a first connecting hole 111. The first input pole 311 and the second input pole 312 are both disposed in the first connecting hole 111 and are both connected to the conductive member 2.

[0076] It is understood that one of the first input electrode 311 and the second input electrode 312 is used for positive input and the other for negative input. Both the first input electrode 311 and the second input electrode 312 are disposed in the first connecting hole 111, and at least a portion of the first input electrode 311 and the second input electrode 312 are disposed in the heat exchange channel 16, so that the refrigerant can also directly cool or heat the first input electrode 311 and the second input electrode 312, thereby improving the heat exchange efficiency of the input electrode 31.

[0077] The conductive element 2 includes a first conductive element 21 and a second conductive element 22 spaced apart. The first conductive element 21 is adapted to be connected to the first input electrode 311, and the second conductive element 22 is adapted to be connected to the second input electrode 312, thereby realizing the input of positive and negative electrodes.

[0078] In some embodiments of this utility model, such as Figures 1-4 , Figure 7 and Figure 8 As shown, the connector 30 includes an output electrode 32, one end of which is used for electrical connection with an electrical component. The output electrode 32 includes a third conductor 321. The connecting hole 11 includes a second connecting hole 112. The third conductor 321 passes through the second connecting hole 112 and is connected to the conductive component 2. At least a portion of the output electrode 32 is disposed in the heat exchange channel 16, thereby allowing the refrigerant to directly cool the output electrode 32, improving heat exchange efficiency. The arrangement of the output electrode 32 allows the current from the input electrode 31 to flow to the electrical component, thus ensuring the normal operation of the electrical component.

[0079] Furthermore, such as Figures 1-4 , Figure 7 and Figure 8 As shown, there are multiple output poles 32. The conductive element 2 includes a first conductive element 21 and a second conductive element 22. One of the first conductive element 21 and the second conductive element 22 is a positive pole and the other is a negative pole. A portion of the multiple output poles 32 is connected to the first conductive element 21 and another portion is connected to the second conductive element 22, thereby realizing the output of positive and negative current and enabling the normal operation of the electrical components.

[0080] Furthermore, such as Figures 1-4As shown, the heat exchange module 10 also includes a fuse 4, which is connected to two output terminals 32, both of which are connected to the conductive element 2 that outputs positive current. The fuse 4 is used to disconnect the circuit when the current is too high, further improving safety.

[0081] For example in Figures 1-4 In the example shown, there are five output poles 32, but the present invention is not limited to this. The number of output poles 32 can be other, such as 3, 4, 6 or 8.

[0082] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the first input pole 311 includes a first conductor 3111, the connecting groove includes a first connecting groove 3114, the fastener includes a first fastener 3113, the first fastener 3113 is disposed in the first connecting groove 3114, and the first conductor 3111 is adapted to be connected to the first conductive element 21.

[0083] It is understandable that the setting of the first fastener 3113 and the first connecting groove 3114 allows the first conductor 3111 and the external conductor to be connected, and the connection between the first conductor 3111 and the first conductive element 21 allows current to be input into the first conductive element 21, thereby realizing the input of current.

[0084] In some embodiments of this utility model, the second input pole 312 includes a second conductor 3121, the connecting groove includes a second connecting groove 3124, the fastener includes a second fastener 3123, the second fastener 3123 is disposed in the second connecting groove 3124, and the second conductor 3121 is adapted to be connected to the second conductive member 22.

[0085] It is understandable that the setting of the second fastener 3123 and the second connecting groove 3124 allows the second conductor 3121 and the external conductor to be connected, and the connection of the second conductor 3121 and the second conductive element 22 allows current to be input into the conductive element 2, thereby realizing the input of current.

[0086] In some embodiments of this utility model, such as Figures 1-4 , Figure 7 and Figure 8 As shown, the connecting groove includes a third connecting groove 3211, the fastener includes a third fastener 322, the third fastener 322 is disposed in the third connecting groove 3211, and the third conductor 321 is adapted to be connected to the conductive member 2.

[0087] It is understandable that the third fastener 322 is located in the third connecting groove 3211, so that the third conductor 321 and the external conductor can be connected, thereby realizing the connection between the third conductor 321 and the conductive component 2, so that the current can be output to the electrical component and realize the output of current.

[0088] In some embodiments of this utility model, such as Figures 1-8 As shown, the connection structure also includes an insulating seal, which passes through the connecting hole. One end of the connector 30 passes through the insulating seal and is electrically connected to the conductive component. It is understandable that the insulating seal serves two purposes: firstly, it prevents the connector 30 from being electrically connected to the heat exchange plate assembly 1, thus avoiding risks such as leakage; secondly, it also prevents refrigerant leakage.

[0089] The connector 30 can be made of copper, and the insulating seal can be made of ceramic. The insulating seal is connected to the connector 30 by means of brazing, and the insulating seal is connected to the heat exchange plate assembly 1 by means of brazing. Of course, this utility model is not limited to this; the insulating seal can also be made of cured adhesive, etc.

[0090] Furthermore, such as Figures 1-8 As shown, the insulating seal includes a first insulating seal 3112, a second insulating seal 3122, and a third insulating seal 323. The first insulating seal 3112 and the second insulating seal 3122 pass through the first connecting hole 111. The first conductor 3111 passes through the first insulating seal 3112, the third insulating seal 323 passes through the second connecting hole 112, and the third conductor 321 passes through the third insulating seal 323. The first insulating seal 3112 is connected to the second insulating seal 3122. This allows the first input electrode 311 and the second input electrode 312 to be formed as a single unit, enabling simultaneous installation of both the first input electrode 311 and the second input electrode 312 into the first connecting hole 111, thus improving installation efficiency.

[0091] In some embodiments of this utility model, such as Figures 1-4 and Figures 10-13 As shown, the connection structure 3 includes: a contactor assembly 33, which includes a contactor body 331 and a contact post 332. The connecting hole 11 includes a third connecting hole 11311. The contactor body 331 passes through the third connecting hole 11311, and the contact post 332 is located at the end of the contactor body 331 facing the conductive element 2 and is connected to the conductive element 2.

[0092] It should be noted that the contactor assembly 33 is connected to the conductive element 2. When the battery pack malfunctions, such as overcharging, over-discharging, short circuit, or abnormal temperature, the contactor assembly 33 can quickly disconnect the circuit to prevent the fault from spreading and avoid battery damage.

[0093] It is understood that the contact post 332 is located at the end of the contactor body 331 facing the conductive element 2 and is connected to the conductive element 2. At least part of the contactor body 331 and the contact post 332 are located in the heat exchange channel 16. Thus, the refrigerant can directly cool or heat the contactor assembly 33, thereby improving the heat exchange efficiency.

[0094] Furthermore, the contactor body 331 includes a housing, a coil, a moving contact, and other structures. The structure of the contactor body 331 is well-known to those skilled in the art and will not be described in detail here. The housing of the contactor body 331 is an insulating component, such as a ceramic component, which on the one hand prevents leakage and improves safety, and on the other hand achieves sealing to prevent refrigerant leakage. The peripheral wall of the contactor body 331 is connected to the heat exchange plate assembly 1 by means of brazing, etc. Of course, this utility model is not limited to this; the peripheral wall of the contactor body 331 can also be a cured adhesive component, etc.

[0095] Furthermore, improved heat exchange efficiency means that the heat generated by the contactor assembly 33 during operation can be dissipated more quickly, thus reducing the temperature rise of the contactor assembly 33. Therefore, under the same heat load, the contactor assembly 33 does not need to reserve excessive space for heat dissipation, allowing for a smaller size and reduced costs. Simultaneously, good cooling reduces oxidation and wear of the contacts caused by high temperatures, extending their service life. Since the degradation rate of contacts slows down at high temperatures, a smaller contactor assembly 33 can be selected. Moreover, the temperature rise of the contactor assembly 33 directly affects its performance and reliability. High heat exchange efficiency ensures that the temperature rise of the contactor assembly 33 remains within a safe range even under continuous operating conditions, thus allowing for the selection of a smaller contactor assembly 33. Efficient cooling also enables the contactor assembly 33, even in a smaller form factor, to carry the same or higher current.

[0096] Furthermore, such as Figures 10-13 As shown, the contact posts 332 are multiple spaced apart, some of which are positive contact posts 332 and some are negative contact posts 332. This improves the connection reliability between the contactor assembly 33 and the conductive element 2, thereby improving the overcurrent capacity.

[0097] In some embodiments of this utility model, such as Figures 10-13 As shown, the contactor assembly 33 also includes a magnetic element 333, with magnetic elements 333 on both opposite sides of the contact pole 332. It is understood that the presence of magnetic elements 333 on both opposite sides of the contact pole 332 creates a magnetic field between the magnetic elements 333 on opposite sides of the contact pole 332, thereby facilitating arc extinguishing between the moving and stationary contacts.

[0098] In some embodiments of this utility model, such as Figures 10-13 As shown, the contactor body 331 has a limiting groove 3311 on the side facing the heat exchange channel 16, and a magnetic component 333 is disposed in the limiting groove 3311, which has an adhesive layer. This allows the magnetic component 333 to be bonded in the limiting groove 3311, improving the installation reliability and stability of the magnetic component 333, thereby ensuring the reliability of arc extinguishing between the moving and stationary contacts.

[0099] In some embodiments of this utility model, such as Figures 1-4 As shown, the heat exchange plate assembly 1 includes a cooling plate body 12 and a cover plate 13. The cover plate 13 covers the cooling groove 121, and a heat exchange channel 16 is formed between the cover plate 13 and the groove wall of the cooling groove 121. It should be noted that the cooling groove 121 can be located on one side of the cooling plate body 12 in the thickness direction. The cover plate 13 and the cooling plate body 12 need to be sealed together, such as by welding, to prevent refrigerant leakage.

[0100] It is understandable that a heat exchange channel 16 is formed between the cover plate 13 and the wall of the cooling tank 121, which simplifies the formation and processing of the heat exchange channel 16 and improves manufacturing efficiency.

[0101] In some embodiments of this utility model, such as Figures 1-4 and Figure 9 As shown, the heat exchange module 10 further includes a fixing member 14, which is disposed between the conductive element 2 and the inner wall of the heat exchange channel 16, and is used to fix the conductive element 2 (for example, the conductive element 2 is connected to the inner wall of the heat exchange channel 16 through the fixing member 14). It can be understood that the fixing member 14 is used to fix the conductive element 2 in the heat exchange channel 16, preventing the conductive element 2 from moving in the heat exchange channel 16, thereby improving the installation stability and reliability of the conductive element 2.

[0102] The conductive element 2 includes a first conductive element 21 and a second conductive element 22 spaced apart, and at least two fixing elements 14 are used to fix and connect the first conductive element 21 and the second conductive element 22, respectively. For example, in... Figures 1-4 and Figure 9 In the example shown, there are two fasteners 14, but the present invention is not limited to this. There can be more fasteners 14, such as 3, 4, 5 or 6.

[0103] Furthermore, the fixing member 14 is an insulating member, thereby achieving insulation between the conductive member 2 and the inner wall of the heat exchange channel 16, thus preventing leakage and improving safety. The fixing member 14 can be a ceramic member, and the connection between the fixing member 14 and the inner wall of the heat exchange channel 16 can be such as brazing. Of course, this utility model is not limited to this; the fixing member 14 can also be a cured adhesive member, etc.

[0104] In some embodiments of this utility model, such as Figures 1-4 and Figure 9 As shown, the heat exchange channel 16 has a first positioning groove 17 on the inner wall of one side along the thickness direction of the heat exchange plate assembly 1. At least a portion of the fixing member 14 is disposed in the first positioning groove 17. The first positioning groove 17 is used to position the fixing member 14 (for example, by connecting the fixing member 14 to the inner wall of the first positioning groove 17, thereby limiting the fixing member 14 within the first positioning groove 17). It can be understood that by placing the fixing member 14 in the first positioning groove 17, the initial positioning of the fixing member 14 is achieved, facilitating quick installation of the fixing member 14 and improving installation efficiency. At the same time, the setting of the first positioning groove 17 also limits the fixing member 14 in the horizontal direction of the heat exchange plate assembly 1, making the installation of the fixing member 14 more reliable and stable.

[0105] In some embodiments of this utility model, such as Figure 9 As shown, the heat exchange module 10 also includes: a reinforcing member 15, a second positioning groove 141 on the side of the fixing member 14 facing the conductive member 2, the reinforcing member 15 being disposed in the second positioning groove 141, the reinforcing member 15 being connected to the groove wall of the second positioning groove 141 and connected to the conductive member 2.

[0106] Understandably, the addition of the reinforcing member 15 increases the structural rigidity of the fixing member 14, thereby reducing its deformation and making the connection between the fixing member 14 and the conductive member 2 more stable and reliable. The reinforcing member 15 is a metal component, and the connection between the reinforcing member 15 and the conductive member 2 is, for example, through welding. The connection between the reinforcing member 15 and the fixing member 14 is, for example, through brazing.

[0107] In some embodiments of this utility model, such as Figures 1-4 As shown, there are multiple heat exchange channels 16 that are spaced apart but connected, and the conductive element 2 is disposed in one of the heat exchange channels 16. For example, in Figures 1-4 In the example shown, the heat exchange channels 16 extend along the length direction of the heat exchange plate assembly 1, and there are multiple heat exchange channels 16 that are spaced apart and connected in the width direction of the heat exchange plate assembly 1. Of course, the present invention is not limited to this, and the heat exchange channels 16 may also extend along the width direction of the heat exchange plate assembly 1, and there may be multiple heat exchange channels 16 that are spaced apart and connected in the length direction of the heat exchange plate assembly 1.

[0108] It is understandable that the heat exchange channels 16 are multiple spaced apart and connected, so that the overall heat exchange channels 16 can meander and extend in the heat exchange plate assembly 1, thereby increasing the coverage of the overall heat exchange channels 16 in the heat exchange plate assembly 1, making the heat exchange uniform in each area of ​​the heat exchange plate assembly 1, and improving the heat exchange efficiency.

[0109] For example in Figures 1-4In the example shown, there are two heat exchange channels 16, but the present invention is not limited to this. There can be more heat exchange channels 16, such as 3, 4, 5 or 6.

[0110] Furthermore, such as Figure 14 As shown, multiple heat exchange channels 16 can be connected in series, thereby maximizing the flow rate through each heat exchange channel 16, ensuring the flow rate through each heat exchange channel 16, and improving heat exchange efficiency.

[0111] Furthermore, such as Figure 15 As shown, multiple heat exchange channels 16 can also be connected in parallel, so that the refrigerant can enter multiple heat exchange channels 16 at the same time for heat exchange, thereby increasing the heat exchange rate and further improving the heat exchange efficiency.

[0112] In some embodiments of this utility model, such as Figures 1-4 As shown, the heat exchange plate assembly 1 is provided with a first port 181 and a second port 182, both of which are connected to the heat exchange channel 16. It can be understood that one of the first port 181 and the second port 182 is an inlet and the other is an outlet. This allows the refrigerant to flow in from one of the first port 181 and the second port 182 and out from the other, enabling better refrigerant flow within the heat exchange channel 16 and improving heat exchange efficiency.

[0113] For example, in this utility model, the first port 181 is for import and the second port 182 is for export. However, this utility model is not limited to this. It is also possible that the first port 181 is for export and the second port 182 is for import.

[0114] Among them, such as Figures 1-4 As shown, the first opening 181 and the second opening 182 are both located on the periphery of the heat exchange plate assembly 1, thereby providing installation space for the end face of the heat exchange plate assembly 1 in the thickness direction, which facilitates better installation of electrical components, etc. However, the present invention is not limited to this, and the first opening 181 and the second opening 182 may also be located on the end face of the heat exchange plate assembly 1 in the thickness direction.

[0115] In some embodiments of this utility model, such as Figures 1-4 As shown, the heat exchange plate assembly 1 has a mounting hole 191 on one side in the thickness direction. The mounting hole 191 is connected to the heat exchange channel 16. The mounting hole 191 is used to install electrical components, such as OBC (On-Board Charger) cooling modules, front and rear electronic control modules, compressors or PTC modules, etc.

[0116] Understandably, the mounting hole 191 is connected to the heat exchange channel 16, allowing the refrigerant to directly cool or heat the electrical components in the mounting hole 191, thereby improving heat exchange efficiency. Simultaneously, the side of the electrical components facing the cooling channel can be sealed off from the mounting hole 191 (e.g., through the connection between the mounting plate and the wall of the mounting hole 191), thus preventing refrigerant leakage from the mounting hole 191.

[0117] Furthermore, such as Figures 1-4 As shown, the mounting holes 191 are a plurality of holes spaced apart along the length of the heat exchange plate assembly 1, thereby allowing multiple electrical components to be installed, so that all multiple electrical components can be directly cooled by the refrigerant, further improving the heat exchange efficiency.

[0118] For example in Figures 1-4 In the example shown, there are 3 mounting holes 191, but the present invention is not limited to this. The number of mounting holes 191 can also be other, such as 2, 4, 5 or 6.

[0119] Furthermore, such as Figures 1-4 As shown, the heat exchange channels 16 extend along the length of the heat exchange plate assembly 1. There are multiple heat exchange channels 16 that are spaced apart and connected in the width direction of the heat exchange plate assembly 1. Each heat exchange channel 16 has a channel opening 162 at the same end of its wall along the length direction of the heat exchange plate assembly 1. The mounting hole 191 includes a first hole 1911 and a second hole 1912. The heat exchange channels 16 and the first hole 1911 are directly connected in the thickness direction of the heat exchange plate assembly 1. The heat exchange channels 16 and the second hole 1912 are spaced apart. The channel opening 162 is connected to the second hole 1912, so that the refrigerant can flow between the second hole 1912 and the heat exchange channels 16 through the channel opening 162 to cool or heat the electrical components in the second hole 1912. By setting the channel opening 162, two adjacent heat exchange channels 16 can be connected, so that the refrigerant can flow in multiple heat exchange channels 16.

[0120] In some embodiments of this utility model, such as Figures 1-4 As shown, the heat exchanger plate assembly 1 has a mounting protrusion 19 on one side along its thickness direction, and a mounting hole 191 passes through the mounting protrusion 19 along the thickness direction of the heat exchanger plate assembly 1. It can be understood that the mounting protrusion 19 can better limit the movement of electrical components, thereby improving the installation stability and reliability of the electrical components.

[0121] Furthermore, such as Figures 1-4 As shown, the mounting protrusions 19 are multiple ones that correspond one-to-one with the multiple mounting holes 191, so that when multiple electrical components are installed, each electrical component can be limited by the mounting protrusions 19, thereby improving the installation stability and reliability of multiple electrical components.
