[0057] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0058] It should be clear that the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other technical solutions obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0059] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0060] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0061] like Figure 1 As shown, the embodiment of the present application provides a cold plate 1, which is used to perform heat exchange with an object to be heat exchanged. The cold plate 1 may include a first main body 11, a second main body 12 and at least one first fin 13, such as Figure 2 and Figure 3 As shown, the first main body 11 has a housing cavity 111, and the housing cavity 111 can be recessed relative to the first main body 11 along the first direction X, and the second main body 12 is located on one side of the first main body 11 along the first direction X and connected to the first main body 11, and the second main body 12 can be used to block the housing cavity 111. The first direction X is the thickness direction of the cold plate 1. The housing cavity 111 is provided with a first protrusion 112, and the first protrusion 112 is arranged on the side wall of the housing cavity 111. The cross-section of the first protrusion 112 can be triangular, rectangular, polygonal, circular, runway-shaped, etc. The first protrusion 112 protrudes along the first direction X. The first fin 13 is arranged in the housing cavity 111. Along the second direction Z, the first protrusion 112 is located on one side or two opposite sides of the first fin 13. The second direction Z is the length direction or width direction of the cold plate 1. In the illustration of this application, the width direction of the cold plate 1 is taken as the second direction Z.

[0062] By providing the first protrusions 112 on opposite sides of the first fin 13, the heat exchange medium flows from opposite sides of the first protrusions 112, so that the first protrusions 112 can be used to divert or collect the heat exchange medium, and the first protrusions can form a more complex flow channel structure in the cold plate, so that the heat exchange medium can flow more evenly in the cold plate 1, which is conducive to evenly distributing the heat exchange medium in the cold plate 1. When the heat exchange medium flows through the first fin 13, turbulence in different directions can be formed, which is conducive to improving the utilization rate of the heat exchange medium, so that the heat exchange medium can better exchange heat with the object to be heat exchanged, which is conducive to improving the heat transfer efficiency. Compared to the solution of forming a heat exchange medium flow channel in the first main body 11 by stamping, in the solution provided by the embodiment of the present application, by setting the first fin 13 inside the cold plate 1, the first protrusion 112 and the first fin 13 support the cold plate 1, which is beneficial to improve the structural strength of the cold plate 1. When in use, the possibility of deformation of the cold plate 1 can be reduced, which is beneficial to improve the contact stability between the cold plate 1 and the object to be heat exchanged, thereby improving the heat exchange efficiency. At the same time, compared to the solution of stamping, the embodiment of the present application has a relatively low cost while having a high structural strength.

[0063] After testing, the surface flatness of the cold plate 1 provided in the embodiment of the present application is less than or equal to 0.08 mm under a pressure of 12 MPa. When the cold plate 1 is subjected to force, it can better maintain its shape, so that the contact between the cold plate 1 and the object to be heat exchanged is more stable and the fit is more tight, which is conducive to sufficient heat transfer between the cold plate 1 and the object to be heat exchanged, improves the thermal conductivity of the cold plate 1, and is more in line with actual use requirements.

[0064] like Figure 3 As shown, in a possible embodiment, at least two first protrusions 112 are provided along the second direction Z, and a first gap 114 is provided between at least two first protrusions 112. This allows the heat exchange medium to flow between adjacent first protrusions 112 along the third direction Y. The number of first protrusions 112 may be two, three, four, five or more, and the first gap 114 is located between adjacent first protrusions 112. When the cold plate 1 includes a plurality of first protrusions 112, the cross-sectional shape of each first protrusion 112 may be the same or different, and first protrusions 112 of different shapes may be provided according to actual needs, so as to facilitate the flow of the heat exchange medium in the accommodating cavity 111, which is beneficial for uniform distribution of the heat exchange medium in the cold plate 1.

[0065] By arranging a plurality of first protrusions 112 at intervals along the second direction Z, it is possible to facilitate the diversion or confluence of the heat exchange medium through the first protrusions 112, and the heat exchange medium can flow between the first protrusions 112 in the second direction Z and / or the third direction Y. This is conducive to uniform distribution of the heat exchange medium in the cold plate 1, thereby improving the heat exchange efficiency of the cold plate 1.

[0066] When the size of the first protrusion 112 is small, the first protrusion 112 has little effect on the flow of the heat exchange medium, which is not conducive to the diversion of the heat exchange medium. When the size of the first protrusion 112 is large, the first protrusion 112 occupies a large space, which will affect the flow of the heat exchange medium in the cold plate 1. The specific size of the first protrusion 112 can be set according to actual usage requirements. By adjusting the size of the first protrusion 112, the diversion and collection effects of the corresponding position on the heat exchange medium can be adjusted.

[0067] like Figure 3 As shown, in a possible implementation manner, along the third direction Y, the cold plate 1 is provided with at least two first protrusions 112, and a second gap 115 is provided between the at least two first protrusions 112. The third direction Y may be perpendicular to the first direction X and the second direction Z. Usually, the first direction X is the thickness direction of the cold plate 1, the second direction Z is the width direction of the cold plate 1, and the third direction Y is the length direction of the cold plate 1.

[0068] By providing a plurality of first protrusions 112 along the third direction Y, the heat exchange medium can be easily divided or collected along the length direction of the cold plate 1 , so that the heat exchange medium can be evenly distributed in the cold plate 1 , thereby improving the heat exchange efficiency of the cold plate 1 .

[0069] like Figure 1 As shown, in a possible implementation manner, the cold plate 1 includes at least two first fins 13, and the number of the first fins 13 can be two, three, four, five or more. The first fins 13 are arranged along the third direction Y.

[0070] Increasing the number of the first fins 13 is conducive to forming turbulence in different directions for the heat exchange medium, thereby facilitating uniform distribution of the heat exchange medium in the cold plate 1 and improving the utilization rate of the heat exchange medium. At the same time, providing a plurality of first fins 13 can be conducive to supporting the cold plate 1, improving the structural strength of the cold plate 1, and reducing the possibility of deformation of the cold plate 1 due to stress, thereby improving the stability of the contact between the cold plate 1 and the object to be heat exchanged, thereby improving the heat exchange efficiency.

[0071] like Figure 1 As shown, at least one end of the first fin 13 is provided with at least two first protrusions 112 along the second direction Z. The cold plate 1 is provided with a plurality of first protrusions 112. The cold plate 1 is provided with a plurality of first protrusions 112 along the second direction Z, and at the same time, a plurality of first protrusions 112 may also be provided along the third direction Y. The first protrusions 112 along the third direction Y are in the same row, and the cold plate 1 may be provided with a plurality of rows of first protrusions 112 along the second direction Z.

[0072] By increasing the number of the first protrusions 112 , the diversion effect of the first protrusions 112 on the heat exchange medium can be improved, so that the heat exchange medium can be evenly distributed in the cold plate 1 , which is beneficial to improving the heat exchange efficiency.

[0073] like Figure 3 As shown, in a possible embodiment, the accommodating cavity 111 is provided with at least one second protrusion 113, and the at least one second protrusion 113 protrudes along the first direction X, and along the third direction Y, the second protrusion 113 is located on one side or both sides of the first fin 13, that is, along the third direction Y, the first fin 13 can be located between adjacent second protrusions 113.

[0074] By providing the second protrusion 113, the heat exchange medium can be further diverted. When the heat exchange medium flows along the third direction Y, the heat exchange medium flows through the opposite sides of the second protrusion 113, which is beneficial to improve the uniform distribution of the heat exchange medium on the cold plate 1, thereby improving the heat exchange efficiency of the cold plate 1 and better meeting actual usage requirements.

[0075] like Figure 3 As shown, in a possible implementation, along the second direction Z, the cold plate 1 is provided with at least two second protrusions 113, and a third gap 116 is provided between the at least two second protrusions 113. The number of the second protrusions 113 may be two, three, four or more.

[0076] The second protrusions 113 can be arranged at intervals along the second direction Z. By providing a plurality of second protrusions 113, the diversion effect on the heat exchange medium can be improved, thereby facilitating the uniform distribution of the heat exchange medium in the cold plate 1, improving the utilization rate of the heat exchange medium and the heat exchange efficiency of the cold plate 1, and better meeting actual usage requirements.

[0077] The second protrusions 113 can also support the cold plate 1 and improve the structural strength of the cold plate 1. In a possible implementation, the first protrusions 112 are arranged along the third direction Y, and the second protrusions 113 are arranged along the second direction Z.

[0078] Through such a design, the first protrusion 112 and the second protrusion 113 can support the cold plate 1 in different directions, thereby improving the structural strength of the cold plate 1 and reducing the possibility of deformation of the cold plate 1 due to force. This is not only beneficial to extending the service life of the cold plate 1 and reducing the possibility of damage, but also can improve the stability of the contact between the cold plate 1 and the object to be heat exchanged, which is more in line with actual usage requirements.

[0079] The distance between adjacent second protrusions 113 along the third direction Y can be set according to the size of the first fin 13, so that the fin can be located between the second protrusions 113. The second protrusions 113 can not only play the role of diversion, but also play the role of limiting, which can improve the relative position accuracy between the first fin 13 and the first main body 11. By adjusting the distance between adjacent second protrusions 113 along the second direction Z, the distribution of the heat exchange medium in the cold plate 1 can be adjusted, which is conducive to the uniform distribution of the heat exchange medium in the cold plate 1.

[0080] like Figure 4 As shown, in a possible embodiment, the first fin 13 includes a first crest portion 131 and a first trough portion 132, and the first crest portion 131 and the first trough portion 132 are arranged at intervals along the third direction Y, that is, along the third direction Y, the structure of the first fin 13 is arranged according to the rule of first crest portion 131—first trough portion 132—first crest portion 131—first trough portion 132. Figure 5 As shown, the first fin 13 is provided with a recessed portion 133 , and the recessed portion 133 is recessed along the third direction Y.

[0081] Such a design can form a serrated fin, and by providing the recessed portion 133, the first fin 13 can also form a structure similar to crests and troughs along the second direction Z, which is beneficial for the first fin 13 to divert the heat exchange medium. When the heat exchange medium flows through the first fin 13, turbulence in different directions can be generated, which is beneficial for the heat exchange medium to flow in different directions and be evenly distributed in the cold plate 1.

[0082] Through such a design, the first fin 13 can form a zigzag structure, and the concave portion 133 can be formed by cutting along the longitudinal direction of the first fin 13. Such a design can form turbulence in different directions when the heat exchange medium flows through the first fin 13, which is conducive to the uniform distribution of the heat exchange medium in the cold plate 1 and improves the utilization rate of the heat exchange medium. The first fin 13 can be made of a plate material so that the first dimension has a higher structural dimension, so that the cold plate 1 can be supported by the first fin 13, reducing the possibility of deformation of the cold plate 1 under stress.

[0083] like Figure 6 As shown, the dotted arrow represents the flow direction of the heat exchange medium in the first main body 11 (the first fins 13 are not shown).

[0084] like Figure 7As shown, an embodiment of the present application further provides a heat exchanger, which includes at least one cold plate 1 and at least one condenser 2, and the cold plate 1 and the condenser 2 are connected. The cold plate 1 includes a first main body 11, a second main body 12 and at least one first fin 13, the first fin 13 is arranged in a receiving cavity 111 of the first main body 11, the receiving cavity 111 is provided with a first protrusion 112 protruding along the first direction X, and the first protrusion 112 is provided on at least one side of the first fin 13 along the second direction Z. The cold plate 1 can be the cold plate 1 involved in any of the above embodiments. Since the cold plate 1 has the above technical effects, the heat exchanger including the cold plate 1 also has the corresponding technical effects, which will not be repeated here.

[0085] like Figure 7 As shown, in a possible implementation manner, along the gravity direction, the condenser 2 is located above the cold plate 1. The condenser 2 and the cold plate 1 are connected through a pipeline 4, and the pipeline 4 includes a first pipeline 41 and a second pipeline 42. The first pipeline 41 is connected to the upper part of the cold plate 1, and the second pipeline 42 is connected to the lower part of the cold plate 1. The cold plate 1 can allow the heat exchange medium to enter the condenser 2 along the first pipeline 41. The condenser 2 can allow the heat exchange medium to enter the cold plate 1 along the second pipeline 42.

[0086] With such a design, the heat exchange medium can be circulated in the cold plate 1 and the condenser 2 by utilizing thermal siphon. The cold plate 1 is used to contact with the object to be exchanged for heat exchange. The heat exchange medium of the cold plate 1 evaporates after absorbing heat, and changes from liquid to gas. The gas flows to the condenser 2 along the first pipeline 41, and heat is exchanged in the condenser 2, and changes from gas to liquid. The liquid can flow back to the cold plate 1 along the second pipeline 42, thereby realizing the circulation of the heat exchange medium. Usually, after the liquid absorbs heat and is converted into gas, it will flow upward. The connection between the first pipeline 41 and the upper part of the cold plate 1 can facilitate the gas to enter the first pipeline 41 and enter the condenser 2 along the first pipeline 41. After the heat exchange medium is converted into liquid in the condenser 2, it flows back to the lower part of the cold plate 1 along the second pipeline 42. As the amount of refluxed liquid increases, the level of the heat exchange medium in the cold plate 1 gradually rises. Such a design is conducive to reducing the flow velocity of the heat exchange medium in the cold plate 1, so that the heat exchange medium can fully exchange heat with the object to be heat exchanged in the cold plate 1, which is conducive to improving the utilization rate of the heat exchange medium and is more in line with actual usage needs.

[0087] In a possible implementation, the condenser 2 is tilted relative to the horizontal direction, the first pipeline 41 is connected to the higher end of the condenser 2, and the second pipeline 42 is connected to the lower end of the condenser 2. After the gaseous heat exchange medium enters the condenser 2, heat exchange is performed and converted into liquid, and the liquid heat exchange medium can flow to the lower position of the condenser 2, so that the heat exchange medium flows back to the cold plate 1 through the second pipeline 42, thereby realizing the recycling of the heat exchange medium.

[0088] like Figure 8and Fig. 9 As shown, in a possible embodiment, the condenser 2 includes a header 21, a second fin 22 and a flat tube 23, the flat tube 23 is connected to the header 21, the heat exchange medium can flow between the header 21 and the flat tube 23, and the second fin 22 is installed on the header 21 and is located between adjacent flat tubes 23. The flat tube 23 extends along the width direction of the condenser 2. The second fin 22 includes at least one second wave crest portion 221 and at least one second wave valley portion 222, and the second wave crest portion 221 and the second wave valley portion 222 are arranged at intervals along the fourth direction M, and the fourth direction M can be the length direction of the condenser 2. The second fin 22 includes at least one third wave crest portion 223 and at least one third wave valley portion 224, and the third wave crest portion 223 and the third wave valley portion 224 are arranged at intervals along the fifth direction N. The fifth direction N can be the width direction of the condenser 2. Along the fourth direction M, at least one third wave crest portion 223 and / or at least one third wave valley portion 224 are located between adjacent flat tubes 23.

[0089] By arranging the second fins 22 between the flat tubes 23, the heat exchange area of ​​the condenser 2 can be increased, the heat exchange efficiency can be improved, and the heat exchange medium can quickly dissipate heat in the condenser 2 and be converted from gas to liquid. The circulation efficiency and heat exchange efficiency of the heat exchange medium of the heat exchanger are improved, which is more in line with actual use requirements. At the same time, the second fins 22 can also provide support for the flat tubes 23, reducing the possibility of deformation of the condenser 2 due to stress.

[0090] like Fig. 9 As shown, in a possible implementation manner, at least a portion of the surface of the third wave peak portion 223 and / or the fourth wave peak portion is an arc-shaped surface.

[0091] By providing curved surfaces at the third wave crest portion 223 and the fourth wave crest portion, the surface area of ​​the second fin 22 can be increased, so that the surface of the second fin 22 forms a structure similar to water ripples, which is beneficial to improving the heat exchange efficiency of the condenser 2. The curved surfaces can also facilitate the flow of media such as air, thereby further improving the heat exchange efficiency of the condenser 2 and facilitating the conversion of the heat exchange medium from gas to liquid.

[0092] The second fin 22 may adopt a rectangular wave non-window design, that is, no through-holes or other structures are provided on the surface of the second fin 22. Such a design can reduce and increase the heat exchange area of ​​the second fin 22, and improve the heat exchange efficiency of the second fin 22. When the second fin 22 is used in an outdoor environment, the possibility of clogging by impurities such as sand and dust can be reduced.

[0093] like Figure 7 As shown, in a possible implementation, the heat exchanger includes at least two condensers 2, and the condensers 2 are connected in series and / or in parallel.

[0094] By providing multiple condensers 2, the heat exchange efficiency can be improved, which is conducive to the heat transfer medium to dissipate heat from gas to liquid. Multiple condensers 2 are arranged in sequence along the height direction of the heat exchange, so that the condensers 2 are stacked. Such a design can save space, help reduce the volume of the heat exchanger and the space occupied, and better meet actual usage needs.

[0095] like Figure 7 and Fig.10 As shown, in a possible implementation, the heat exchanger further includes a mounting bracket 3, the mounting bracket 3 includes a first mounting portion 31 and a second mounting portion 32, the first mounting portion 31 and the second mounting portion 32 are connected to each other and have an angle, and the first mounting portion 31 is located above the second mounting portion 32 along the gravity direction. The condenser 2 is mounted on the first mounting portion 31, and the cold plate 1 is mounted on the second mounting portion 32. Fig.10 The dashed arrow in the middle indicates the flow direction of the heat exchange medium.

[0096] Such a design can facilitate the integration of the cold plate 1 and the condenser 2 , improve the relative position accuracy of the two, and facilitate the circulation of the heat exchange medium between the cold plate 1 and the condenser 2 .

[0097] The first mounting portion 31 and the second mounting portion can be connected by bolts. The first mounting portion 31 includes at least two first connecting portions 311, and the first connecting portions 311 are connected to the condenser 2. The condenser 2 can be provided with a connecting block correspondingly, and the condenser 2 cooperates with the mounting bracket 3 through the connecting block so that the condenser 2 can be installed on the mounting bracket 3.

[0098] The second mounting bracket 3 includes at least two main bodies 321 and at least one second connecting part 322, the main bodies 321 are located on opposite sides of the cold plate 1, and the second connecting parts 322 are connected to the main bodies 321. The connection between the main bodies 321 and the opposite sides of the cold plate 1 can improve the stability of the installation of the cold plate 1. The second connecting parts 322 can be connected to the main bodies 321 as a reinforcing structure, and the second connecting parts 322 can simultaneously connect the main bodies 321 located on both sides of the cold plate 1. According to actual needs, the number of cold plates 1 can be two, three, four or more.

[0099] The mounting bracket 3 may be a sheet metal frame assembly, which can protect the pipe while integrating the condenser 2 and the cold plate 1. The body portion 321 of the second mounting portion 32 may include a first body portion 321a and a second body portion 321b, and the first body portion 321a and the second body portion 321b are connected to each other and have an angle.

[0100] The embodiment of the present application provides a cold plate 1 and a heat exchanger, wherein the cold plate 1 includes a first main body 11, a second main body 12 and at least one first fin 13, wherein the first fin 13 is disposed in a receiving cavity 111 of the first main body 11, wherein the receiving cavity 111 is provided with a first protrusion 112 protruding along a first direction X, and along a second direction Z, the first protrusion 112 is located on one side or both sides of the first fin 13. With such a design, the first protrusion 112 can be used to divert the heat exchange medium, thereby evenly distributing the heat exchange medium in the cold plate 1 and improving the heat exchange efficiency. The first protrusion 112 and the first fin 13 can also strengthen the cold plate 1, improve the structural strength of the cold plate 1, and reduce the possibility of deformation of the cold plate 1 due to stress, thereby improving the stability of the contact between the cold plate 1 and the object to be heat exchanged, which is beneficial to improving the heat exchange efficiency.
