[0002] Heat exchangers are widely used in production and daily life. Existing technology presents a heat exchanger comprising two liquid collecting components and a heat dissipation component connecting the two components.

[0028] This application provides a heat exchange device. Because the liquid collecting element or its main structure can be disassembled into multiple independent installation units, compared to a one-piece liquid collecting element or its main structure, the liquid collecting element of this application has lower requirements for processing molds, reducing development costs and difficulty. Furthermore, when some installation units are damaged, they can be partially repaired or replaced without scrapping the entire liquid collecting element, further reducing costs and maintenance difficulty. When the internal support components of the liquid collecting element are damaged, they can also be quickly disassembled for repair or replacement without scrapping the entire liquid collecting element, again reducing costs and maintenance difficulty.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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 some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] See Figures 1 to 8 This application provides a heat exchange device 10, which includes two liquid collection components 100 and a heat dissipation component 200 connected between the two liquid collection components 100. Each liquid collection component 100 has a cavity 101 for containing a heat exchange medium, and the cavities 101 of both liquid collection components 100 are in communication with the heat dissipation component 200.

[0031] Specifically, the liquid collecting element 100 has a cavity 101 for containing the heat exchange medium. Figure 4 As shown, the heat sink 200 has a heat exchange channel 210 inside. Both ends of the heat sink 200 are connected to two liquid collecting units 100, so that the cavities 101 of both liquid collecting units 100 are in communication with the heat exchange channel 210 of the heat sink 200. In this way, the heat exchange medium inside the two liquid collecting units 100 can flow through the heat exchange channel 210 of the heat sink 200, and the heat exchange medium can dissipate heat to the outside through the heat sink 200 during the flow through the heat exchange channel 210.

[0032] The liquid collecting device 100 may also include a first housing 110 and a second housing 120 that are snapped together. The first housing 110 has a first inner wall 112 and the second housing 120 has a second inner wall 122. The first inner wall 112 and the second inner wall 122 are disposed opposite to each other. The first inner wall 112 and the second inner wall 122 are used to form at least a portion of the wall surface of the cavity 101.

[0033] In some exemplary embodiments, the liquid collecting component 100 may be composed of a first housing 110 and a second housing 120, which are fastened together to form the whole of the liquid collecting component 100, and after the first housing 110 and the second housing 120 are fastened together, a cavity 101 is formed inside.

[0034] See Figure 2 and Figure 5 In some exemplary embodiments, in each liquid collecting component 100, the first housing 110 and the second housing 120 can be fastened together to form a cylindrical main structure, and the left and right sides of the main structure are respectively sealed by the third housing 150 and the fourth housing 160 to form the whole of the liquid collecting component 100, and a cavity 101 is formed inside it.

[0035] Furthermore, the heat exchange device 10 may also include a support member 300, which is disposed in the cavity 101 to support the first housing 110 and the second housing 120, so as to overcome the problem of reduced strength caused by the excessive size of the liquid collecting member 100.

[0036] See Figure 2 , Figure 3 , Figure 5 as well as Figure 7 Furthermore, the support member 300 may include a connecting portion 310 and a plurality of support portions 320 spaced apart. The connecting portion 310 abuts against the first inner wall 112, the first ends of the plurality of support portions 320 are connected to the connecting portion 310, and the second ends of the plurality of support portions 320 abut against the second inner wall 122.

[0037] Specifically, the connecting portion 310 of the support member 300 can be plate-shaped, and one side surface of the connecting portion 310 is in contact with the first inner wall 112 of the first housing 110. The support portion 320 can be column-shaped (cylindrical or prismatic), with the first ends of multiple support portions 320 being connected to the connecting portion 310 at intervals, and the second ends of multiple support portions 320 abutting against the second inner wall 122 of the second housing 120, thus realizing the support of the first housing 110 and the second housing 120 by the support member 300.

[0038] During installation, the support member 300 can be installed inside the first housing 110 or the second housing 120 so that the connecting part 310 abuts against the first inner wall 112 of the first housing 110, or the multiple support parts 320 abut against the second inner wall 122 of the second housing 120. Finally, the first housing 110 and the second housing 120 (and other enclosed housings) are fastened together to complete the installation.

[0039] In this embodiment, the liquid collecting component 100 or its main structure is divided into multiple independent installation units (i.e., the first housing 110 and the second housing 120, etc.). Compared with the integrally formed liquid collecting component 100 or its main structure, the liquid collecting component 100 in this embodiment has lower requirements for processing molds, which reduces development costs and development difficulty.

[0040] In addition, when some installation units are damaged, they can be partially repaired or replaced without the need to scrap the entire liquid collection unit 100, which reduces costs and maintenance difficulty.

[0041] Furthermore, when the support member 300 inside the liquid collecting component 100 is damaged, the support member 300 can be directly exposed by disassembling the first housing 110 and the second housing 120, and the liquid collecting component 100 can be repaired or replaced and then reassembled without having to scrap the entire liquid collecting component 100, which further reduces costs and maintenance difficulty.

[0042] In some embodiments, along the direction from the liquid collecting member 100 to the heat dissipation member 200, in each liquid collecting member 100, the first housing 110 is located away from the heat dissipation member 200 relative to the second housing 120. The second inner wall 122 has a plurality of spaced-apart mounting holes 122a for communicating with the cavity 101, through which the heat dissipation member 200 passes. A plurality of support portions 320 of the support member 300 are staggered with the plurality of mounting holes 122a.

[0043] Along the direction from the liquid collecting component 100 to the heat dissipation component 200, the first housing 110 is farther away from the heat dissipation component 200 relative to the second housing 120. That is, the second housing 120 is relatively close to the two liquid collecting components 100. Since it is connected between the two liquid collecting components 100, the two ends of the heat dissipation component 200 can be connected to the second housing 120 of the two liquid collecting components 100.

[0044] Specifically, the second inner wall 122 of the second housing 120 has a plurality of spaced mounting holes 122a for communicating with the cavity 101. Multiple heat sinks 200 are provided, and each heat sink 200 corresponds one-to-one with a different mounting hole 122a. The first ends of the multiple heat sinks 200 pass through the mounting holes 122a of one of the liquid collecting components 100, and the second ends of the multiple heat sinks 200 pass through the mounting holes 122a of another liquid collecting component 100. This connects the cavities 101 of the two liquid collecting components 100 with the heat exchange channels 210 of the heat sinks 200, allowing the heat exchange medium within the two liquid collecting components 100 to flow through the heat exchange channels 210 of the heat sinks 200.

[0045] Since the support member 300 is disposed inside the cavity 101, and the second ends of the plurality of support portions 320 of the support member 300 abut against the second inner wall 122, and the second inner wall 122 is provided with a plurality of mounting holes 122a for inserting the heat sink 200, the support portion 320 may block the mounting hole 122a, thereby interfering with the heat sink 200.

[0046] In this embodiment, the multiple support portions 320 of the support member 300 are staggered with the multiple mounting holes 122a. This avoids the support portions 320 from being directly opposite the mounting holes 122a, eliminates the influence of the support portions 320 on the mounting holes 122a and the heat sink 200 inserted in the mounting holes 122a, and also eliminates the influence of the support portions 320 on their own support effect.

[0047] In some embodiments, the liquid collecting member 100 is generally in the form of a flat cuboid structure. The direction from the liquid collecting member 100 to the heat dissipation member 200 is consistent with the thickness direction of the liquid collecting member 100.

[0048] Multiple mounting holes 122a are arranged at intervals along the length of the liquid collecting component 100, and multiple heat dissipation components 200 are also arranged at intervals along the length of the liquid collecting component 100, so as to be inserted into the multiple mounting holes 122a.

[0049] Furthermore, the cavity 101 can also be defined as a cuboid structure similar to the liquid collecting member 100, and the connecting part 310 of the support member 300 is in the shape of a square plate. The orientation of the connecting part 310 is set to be consistent with the orientation of the cavity 101 in order to obtain more contact area and improve the support effect.

[0050] Furthermore, in each support member 300, a portion of the support portion 320 is located on the first side of the connecting portion 310 along the width direction of the liquid collecting member 100, and this portion of the support portion 320 is arranged sequentially at intervals along the length direction of the liquid collecting member 100; another portion of the support portion 320 is located on the second side of the connecting portion 310 along the width direction of the liquid collecting member 100, and this portion of the support portion 320 is arranged sequentially at intervals along the length direction of the liquid collecting member 100.

[0051] In other words, in the support member 300, multiple support portions 320 are divided into two rows. The two rows of support portions 320 are respectively disposed on the first side and the second side of the connecting portion 310 along the width direction of the liquid collecting member 100. When the orientation of the connecting portion 310 is consistent with the orientation of the liquid collecting member 100, that is, the two rows of support portions 320 are respectively disposed on the first side and the second side of the width direction of the connecting portion 310, the connecting portion 310 can be supported from both sides by the two rows of support portions 320, so that the balance effect of the support member 300 in the cavity 101 is better and more stable.

[0052] In addition, two of the two rows of support portions 320 can be directly opposite each other in the width direction, which is beneficial to form a staggered arrangement with the mounting hole 122a so as to avoid the mounting hole 122a.

[0053] See Figures 1 to 4 In some embodiments, the two liquid collecting components 100 are a first liquid collecting component 130 and a second liquid collecting component 140, respectively. The cavity 101 of the first liquid collecting component 130 is divided into an inlet cavity 136 and an outlet cavity 138, which are independent of each other. The cavity 101 of the second liquid collecting component 140 is a manifold cavity 144. There are multiple heat dissipation components 200, some of which are used to connect the inlet cavity 136 and the manifold cavity 144, and the remaining heat dissipation components 200 are used to connect the manifold cavity 144 and the inlet cavity 136.

[0054] The first liquid collecting device 130 has an inlet 124 and an outlet 126. The inlet 124 is connected to the inlet chamber 136 for introducing the heat exchange medium, and the outlet 126 is connected to the outlet chamber 138 for discharging the heat exchange medium. The first liquid collecting device 130 may also include an inlet connector 170 and an outlet connector 180. The inlet connector 170 is connected to the inlet 124, and the outlet connector 180 is connected to the outlet 126 for connection to external pipelines.

[0055] Since part of the heat sink 200 is used to connect the inlet chamber 136 of the first liquid collector 130 with the manifold 144 of the second liquid collector 140, and another part of the heat sink 200 connects the manifold 144 of the second liquid collector 140 with the inlet chamber 136 of the first liquid collector 130, during heat exchange, the heat exchange medium is introduced into the inlet chamber 136 of the first liquid collector 130. The heat exchange medium can enter the manifold 144 of the second liquid collector 140 through the heat exchange channel 210 of the heat sink 200, and then enter the outlet chamber 138 of the first liquid collector 130 through the heat exchange channel 210 of the heat sink 200, and finally be discharged from the first liquid collector, forming a cycle, this heat exchange method, because the heat exchange medium flows through the heat sink 200 twice, extends the flow path between the heat exchange medium and the heat sink 200, thus improving the heat dissipation effect.

[0056] Furthermore, in the first liquid collecting component 130, the second inner wall 122 forms at least a portion of the wall surface of the liquid inlet chamber 136. The second inner wall 122 has a plurality of spaced-apart first mounting holes 132, which communicate with the liquid inlet chamber 136. At least a portion of the heat dissipation components 200 are correspondingly disposed through the plurality of first mounting holes 132. Support members 300 are disposed in the liquid inlet chamber 136, and a plurality of support portions 320 are staggered with the plurality of first mounting holes 132.

[0057] Furthermore, in the first liquid collecting component 130, the second inner wall 122 forms at least a portion of the wall surface of the liquid outlet chamber 138. The second inner wall 122 has a plurality of spaced-apart second mounting holes 134 for communicating with the liquid outlet chamber 138. At least a portion of the heat dissipation components 200 are correspondingly disposed through the plurality of second mounting holes 134. The support member 300 is disposed in the liquid outlet chamber 138, and a plurality of support portions 320 are spaced-apart connected to the connecting portion 310 and are staggered from the plurality of second mounting holes 134.

[0058] Specifically, the first housing 110 and the second housing 120 are fastened together along the thickness direction of the first liquid collecting member 130. The first liquid collecting member 130 is divided into an independent inlet chamber 136 and an outlet chamber 138 along its length direction. In this way, the second inner wall 122 of the second housing 120 can simultaneously form part of the wall surface of the inlet chamber 136 and the outlet chamber 138.

[0059] Multiple first mounting holes 132 are arranged at intervals along the length of the first liquid collecting component 130, and multiple second mounting holes 134 are arranged at intervals along the length of the first liquid collecting component 130. Multiple heat sinks 200 are arranged at intervals along the length of the first liquid collecting component 130, and some heat sinks 200 are installed in a one-to-one correspondence with the multiple first mounting holes 132, while other heat sinks 200 are installed in a one-to-one correspondence with the multiple second mounting holes 134.

[0060] Each of the liquid inlet chamber 136 and the liquid outlet chamber 138 is provided with a support member 300. In the support member 300 of the liquid inlet chamber 136, multiple support parts 320 and multiple first mounting holes 132 are staggered in the length direction of the first liquid collector 130. In the support member 300 of the liquid outlet chamber 138, multiple support parts 320 and multiple second mounting holes 134 are staggered in the length direction of the first liquid collector 130, so as to avoid the first mounting holes 132 and the second mounting holes 134 respectively.

[0061] Furthermore, in the second liquid collection component 140, the second inner wall 122 forms at least a portion of the wall surface of the manifold 144. The second inner wall 122 has a plurality of spaced-apart third mounting holes 142 for communicating with the external environment and the manifold 144. A plurality of heat dissipation components 200 are correspondingly disposed through the plurality of third mounting holes 142. A support member 300 is disposed in the manifold 144, and a plurality of support portions 320 are spaced-apart connected to the connecting portion 310 and are staggered with the plurality of third mounting holes 142.

[0062] Multiple third mounting holes 142 are arranged sequentially at intervals along the length of the second liquid collecting component 140, and multiple heat dissipation components 200 are arranged sequentially at intervals along the length of the first liquid collecting component 130, with each heat dissipation component 200 corresponding to one of the multiple third mounting holes 142.

[0063] Each manifold 144 is provided with a support member 300, and multiple support parts 320 in the support member 300 and multiple third mounting holes 142 are staggered in the length direction of the first liquid collecting member 130 to avoid the third mounting holes 142 respectively.

[0064] In some embodiments, the heat exchange device 10 may further include a separator 400 disposed within the cavity 101 of the first liquid collecting member 130 to divide the cavity 101 into an inlet cavity 136 and an outlet cavity 138.

[0065] The separator 400 is plate-shaped and stands upright in the cavity 101 of the first liquid collecting member 130, extending along the width direction of the first liquid collecting member 130 to divide the cavity 101 into an inlet cavity 136 and an outlet cavity 138 in the length direction of the first liquid collecting member 130.

[0066] See Figure 6 In some implementations, the heat exchange device 10 may further include at least one first fin 500, the at least one first fin 500 being disposed between two adjacent heat sinks 200, and each first fin 500 being configured to meander and coil in the direction from the liquid collection member 100 to the heat sink 200 to form a plurality of first bent ends 510, the plurality of first bent ends 510 being attached to the adjacent heat sink 200.

[0067] In this embodiment, multiple heat sinks 200 are arranged sequentially at intervals. A first fin 500 is provided in the interval between two adjacent heat sinks 200. The first fin 500 is meandering and coiled to form multiple first bent ends 510. The first bent ends 510 are attached to the adjacent heat sink 200, so that the cold or heat on the heat sink 200 can be transferred to the first fin 500. The first fin 500 can increase the heat exchange area and improve the heat exchange efficiency.

[0068] Optionally, the multiple first bent ends 510 can be fixed to the adjacent heat sink 200 by welding. This not only ensures that the first bent ends 510 are firmly attached to the heat sink 200, but also allows the multiple heat sinks 200 to be connected together to form a whole through the multiple first fins 500.

[0069] See Figures 1 to 6 In some embodiments, the heat exchange device 10 may further include at least one protective portion 600 and at least one second fin 700. The protective portions 600 are spaced apart on the outer side of the outermost heat sink 200. Each second fin 700 is disposed between the heat sink 200 and the protective portion 600, and each second fin 700 is configured to meander and coil in the direction from the liquid collecting member 100 to the heat sink 200 to form a plurality of second bent ends 710, which are attached to the heat sink 200 and the protective portion 600.

[0070] In this embodiment, the protective part 600 is disposed on the outside of the outermost heat sink 200, serving a protective function. In some specific embodiments, there are two protective parts 600, which can be disposed on the outside of the two outermost heat sinks 200 respectively.

[0071] Since the protective part 600 and the outermost heat sink 200 are spaced apart, and a second fin 700 is provided in each space, the second bent end 710 on the second fin 700 is attached to the heat sink 200 and the bent part, so that the second fin 700 can also increase the heat exchange area and improve the heat exchange efficiency.

[0072] Optionally, multiple second bent ends 710 can be fixed to the heat sink 200 and the protective part 600 by welding. This not only ensures that the second bent ends 710 are firmly attached to the heat sink 200, but also connects the outermost heat sink 200 and the protective part 600 through the second fins 700, so that the protective part 600 and multiple heat sinks 200 form an integral whole.

[0073] See Figure 8In some embodiments, the heat sink 200 is plate-shaped and has a length direction and a width direction. The first end and the second end of the heat sink 200 are the two ends in the length direction of the heat sink 200, respectively. Each heat sink 200 has a plurality of heat exchange channels 210, which are spaced apart along the width direction of the heat sink 200, and each heat exchange channel 210 extends along the length direction of the heat sink 200, with both ends of each heat exchange channel 210 open.

[0074] Each mounting hole 122a may be configured to extend along the width of the liquid collection member 100 so that the heat dissipation member 200 can be inserted therein.

[0075] In this embodiment, the heat sink 200 is generally plate-shaped, and multiple heat exchange channels 210 are arranged at intervals along the width direction of the heat sink 200. This can make full use of the shape of the heat sink 200 to form multiple heat exchange channels 210, increase the flow area of ​​the heat exchange medium, and improve the heat exchange efficiency. On the other hand, the plate-shaped heat sink 200 has a sufficiently large heat exchange area, which can also play a role in improving the heat exchange efficiency.

[0076] In some specific embodiments, the heat exchange channels 210 within each heat sink 200 are configured as microchannels, which can further increase the number of heat exchange channels 210 and improve heat exchange efficiency.

[0077] This application also provides a charging device that can charge electrical equipment such as electric vehicles.

[0078] See Figure 9 In some exemplary embodiments, the charging device may include the heat exchange device 10 in any of the above embodiments, and the heat exchange device 10 may be circulated with a cooled heat exchange medium to cool the internal components of the charging device.

[0079] In some exemplary embodiments, the charging device includes a charging gun 20 and a charging pile 30. The charging gun 20 is the main functional module of the charging device, used to realize the core charging function. The charging gun 20 includes a body 22 and a liquid cooling component 24. The body 22 may include a circuit part and a connection part 310. The circuit part may include a circuit board and some electronic components, while the connection part 310 may include an electrical connector plug for direct connection with the device to be charged. The liquid cooling component 24 may be a liquid cooling plate, etc., and the liquid cooling component 24 is in contact with the body 22 to achieve heat exchange with the body 22.

[0080] The charging pile 30 may also include a liquid cooling heat dissipation unit 32. The liquid cooling heat dissipation unit 32 can be connected to the liquid cooling component 24, and a heat exchange medium (such as water) can circulate between the liquid cooling heat dissipation unit 32 and the liquid cooling component 24. During the charging operation, the heat generated by the main body 22 is directly transferred to the liquid cooling component 24, and can then be absorbed and carried away by the heat exchange medium circulating in the liquid cooling component 24, thereby achieving heat dissipation of the main body 22.

[0081] The liquid cooling heat dissipation unit 32 may include a heat exchange device 10, a liquid storage component 32a, and a pumping component 32b. The outlet of the liquid cooling component 24 can be connected to the inlet 124 of the heat exchange device 10 to introduce the relatively high-temperature heat exchange medium in the liquid cooling component 24 into the heat exchange device 10. The heat dissipation element 200 of the heat exchange device 10 can cool the heat exchange medium. The outlet 126 of the heat exchange device 10 can be connected to the inlet of the liquid storage component 32a to introduce the cooled, relatively low-temperature heat exchange medium back into the liquid storage component 32a. The outlet of the liquid storage component 32a can be connected to the inlet of the pumping component 32b, and the outlet of the pumping component 32b can be connected to the inlet of the liquid cooling component 24. The pumping component 32b provides pumping driving force for the first liquid cooling working fluid in circulation.

[0082] In this embodiment of the heat exchange device 10, the liquid collecting component 100 or its main structure can be disassembled into multiple independent installation units (i.e., the first housing 110 and the second housing 120, etc.), and these installation units are assembled to form the liquid collecting component 100 or its main structure. Compared to a one-piece molded liquid collecting component 100 or its main structure, the liquid collecting component 100 in this embodiment has lower requirements for processing molds, reducing development costs and difficulties. Furthermore, when some installation units are damaged, they can be partially repaired or replaced without scrapping the entire liquid collecting component 100, reducing costs and maintenance difficulty. Additionally, when the internal support member 300 of the liquid collecting component 100 is damaged, the support member 300 can be quickly disassembled for repair or replacement without scrapping the entire liquid collecting component 100, further reducing costs and maintenance difficulty.

[0083] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0084] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0085] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on something” but also “on something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0086] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of devices in use or operation other than those shown in the figures. Devices may have other orientations, and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
