[0041] Please refer to Figures 1 to 12This application discloses a heat exchange structure 100, which includes a first heat exchange unit 1, a second heat exchange unit 2, and a mounting plate 3. The second heat exchange unit 2 is disposed on one side of the first heat exchange unit 1 and is connected to the first heat exchange unit 1 on the same plane.

The second manifold 12 and the third manifold 21 are connected side by side along the length direction. The mounting plate 3 has at least one mounting hole 301 through which the first heat exchange tube 13 and the second heat exchange tube 23 pass, and the wall of the mounting hole 301 is sealed to the first heat exchange tube 13 or the second heat exchange tube 23. This improves the sealing performance between the mounting plate 3 and the first heat exchange tube 13 or the second heat exchange tube 23.

[0042] Please refer to Figure 1 For ease of explanation, the length direction of the heat exchange structure 100 is defined as the first direction D1-D1, the height direction of the heat exchange structure 100 is defined as the second direction D2-D2, and the thickness direction of the heat exchange structure 100 is defined as the third direction D3-D3. The first direction D1-D1, the second direction D2-D2, and the third direction D3-D3 are all perpendicular to each other.

[0043] Please refer to Figures 1 to 6 The first manifold 11, the second manifold 12, the third manifold 21, and the fourth manifold 22 extend along the first direction D1-D1, and are arranged at intervals along the second direction D2-D2.

[0044] Please refer to Figures 1 to 2The mounting plate 3 includes a first substrate 31 and a second substrate 32 attached to the first substrate 31. The first substrate 31 is welded to the first heat exchange tube 13 or the second heat exchange tube 23, and the second substrate 32 is sealed to the first heat exchange tube 13 or the second heat exchange tube 23. In this application, the first substrate 31 is made of non-composite aluminum plate, and the second substrate 32 is made of composite aluminum plate. When the second heat exchange tube 23 passes through the first substrate 31 and the second substrate 32, and solder is provided to weld the mounting plate 3 to the first heat exchange tube 13 or the second heat exchange tube 23, the composite material of the second substrate 32 can fill the gap between the first substrate 31 and the first heat exchange tube 13 or the second heat exchange tube 23, thereby enabling the mounting plate 3 to form a sealed connection with the first heat exchange tube 13 or the second heat exchange tube 23.

[0045] There is a gap between the mounting hole 301 and the wall of the first heat exchange tube 13 or the second heat exchange tube 23. The second substrate 32 includes a first base 321 and a second base 322 attached to both sides of the first base 321, wherein one side of the second base 322 is attached to the first substrate 31, and the second base 322 is configured to fill the gap. Specifically, the shape of the mounting hole 301 is adapted to the shape of the first heat exchange tube 13 and the second heat exchange tube 23, and a plurality of mounting holes 301 are arranged at intervals along a straight line along the length direction of the mounting plate 3, and the distance between two adjacent mounting holes 301 is the same as the distance between two adjacent first heat exchange tubes 13 or second heat exchange tubes 23.

[0046] Please refer to Figure 1 In this embodiment, the first heat exchange unit 1 is the condenser end of the heat exchanger, and the second heat exchange unit 2 is the evaporator end of the heat exchange structure 100. The second heat exchange unit 2 is placed inside the cabinet. The refrigerant inside the second heat exchange unit 2 absorbs heat from the cabinet and becomes a high-temperature, high-pressure gaseous refrigerant. The refrigerant in the second heat exchange unit 2 flows into the first heat exchange unit 1 and exchanges heat with the external ambient air, becoming a low-temperature, low-pressure liquid refrigerant, which can cool the air inside the cabinet. In this embodiment, the mounting plate 3 is fixedly connected to the first heat exchange tube 13, and the mounting plate 3 is connected to the cabinet, preventing external moisture from entering the cabinet, thereby improving the heat exchange efficiency of the second heat exchange unit 2.

[0047] In other embodiments, the first heat exchange unit 1 can also be the evaporation end of the heat exchange structure 100, and the second heat exchange unit 2 can also be the condensation end of the heat exchange structure 100. The first heat exchange unit 1 is placed inside the cabinet. The refrigerant in the first heat exchange unit 1 absorbs heat from inside the cabinet and becomes a high-temperature, high-pressure gaseous refrigerant. The refrigerant in the second heat exchange unit 2 flows into the second heat exchange unit 2 and exchanges heat with the external ambient air, becoming a low-temperature, low-pressure liquid refrigerant, which can cool the air inside the cabinet. In this embodiment, the mounting plate 3 is fixedly connected to the second heat exchange tube 23, and the mounting plate 3 is connected to the cabinet, preventing external moisture from entering the cabinet, thereby improving the heat exchange efficiency of the first heat exchange unit 1.

[0048] Please refer to Figures 1 to 2 The system comprises multiple first heat exchange tubes 13 and multiple second heat exchange tubes 23, with the shape of the mounting hole 301 adapted to either the first heat exchange tube 13 or the second heat exchange tube 23. In embodiments of this application, the first heat exchange tube 13 and the second heat exchange tube 23 are flat tubes with channels inside to allow refrigerant to flow through them. Several fins are provided between adjacent first heat exchange tubes 13 to improve their heat exchange performance. Similarly, several toothed fins are provided between adjacent second heat exchange tubes 23 to improve their heat exchange performance.

[0049] Multiple mounting holes 301 on the mounting plate 3 are arranged at intervals along a straight line along the length of the mounting plate 3, and the distance between two adjacent mounting holes 301 is the same as the distance between two adjacent first heat exchange tubes 13 or two adjacent second heat exchange tubes 23. This allows for precise assembly of the mounting plate 3 with the first heat exchange tube 13 or the second heat exchange tube 23 during assembly. This also reduces the gap between the mounting holes 301 and the first heat exchange tube 13 or the second heat exchange tube 23, thereby improving the waterproof performance of the mounting plate 3.

[0058] The refrigerant flow path of the heat exchanger structure in this application is as follows:

[0059] The second heat exchange unit 2 is installed inside the cabinet. The refrigerant in the second heat exchange unit 2 exchanges heat with the air inside the cabinet through the second heat exchange tube 23, absorbing heat and undergoing a phase change to gaseous state. In one circuit, the gaseous refrigerant enters the first sub-channel cavity from the third sub-channel cavity through the second heat exchange chamber 203 of the second heat exchange tube 23 located on the left side of the sixth manifold 5, then passes through the second port 204 and enters the third end 122. It then flows into the first manifold 101 through the fourth port 403, the fourth manifold 202, and the third port 402 of the fifth manifold 4. The refrigerant in the first manifold 101 flows into the first heat exchange chamber 103 of the first heat exchange tube 13 and absorbs heat from the external environment. At this time, the refrigerant changes from gaseous state to liquid state, and the liquid refrigerant flows into the second manifold 102. In another circuit, gaseous refrigerant enters the second sub-channel cavity from the fourth sub-channel cavity through the second heat exchange chamber 203 of the second heat exchange tube 23 located on the right side of the sixth manifold 5. It then passes through the tenth port 206 and enters the fourth end 123. From there, it flows into the first manifold cavity 101 through the twelfth port 603, the seventh manifold cavity 601, and the eleventh port 602 of the seventh manifold 6. The refrigerant in the first manifold cavity 101 then flows into the first heat exchange chamber 103 of the first heat exchange tube 13 to exchange heat with the external annular absorption heat. At this point, the refrigerant changes from a gaseous state to a liquid state, and the liquid refrigerant flows into the second manifold cavity 102. The liquid refrigerant then enters the sixth end 211 through the fifth port 105 and the fifth fixing hole. It then flows sequentially through the seventh port 502, the sixth manifold cavity 501, and the eighth port 503 of the sixth manifold 5 into the third and fourth sub-channel cavities, respectively, exchanging heat with the hot air inside the cabinet again. This process is repeated to improve heat exchange efficiency.
