[0019] Reference Figure 1 The utility model proposes an efficient heat exchange system, comprising: a heat exchanger, wherein the heat exchanger comprises an evaporator 1, a condenser 2 and a heat pipe 3, wherein:

[0020] The evaporator 1 and the condenser 2 each include a metal tube a1 and a plurality of fins a2 integrated on the metal tube a1. The evaporation section of the heat pipe 3 is integrated with the fins a2 in the evaporator 1, and the condensation section of the heat pipe 3 is integrated with the fins a2 in the condenser 2. Specifically: the evaporation section of the heat pipe 3 is sequentially inserted into and fixed in each fin a2 in the evaporator 1, and the condensation section of the heat pipe 3 is sequentially inserted into and fixed in each fin a2 in the condenser 2, so that the heat pipe 3 and the evaporator 1, as well as the heat pipe 3 and the condenser 2 form a common fin a2 structure, thereby ensuring that the gap between the fins a2 is unobstructed, greatly increasing the heat dissipation area, and reducing wind resistance. Under the same air volume conditions, the heat exchange capacity of the heat pipe 3 can be effectively improved.

[0021] During specific operation: when the temperature inside the cabinet 5 is higher than the phase change start-up temperature, and the temperature difference between the inside and outside of the cabinet 5 is higher than the temperature difference setting, and the outdoor temperature is lower than the phase change start-up outdoor temperature setting, the heat exchange mode is turned on, the heat pipe 3 is an integrated structure, and the air passes through the parallel fins a2, the wind resistance is reduced to a lower value, and a larger air volume brings the cooled air into the cabinet 5, achieving a higher phase change heat dissipation purpose.

[0022] When the temperature inside the cabinet 5 is lower than the phase change stop temperature, or the temperature difference between the inside and outside of the cabinet 5 is lower than the temperature difference setting of -3°C, or the outdoor temperature is higher than the phase change start outdoor temperature setting of +3°C, heat exchange is stopped.

[0023] The utility model proposes an efficient heat exchange system, which also includes a compressor 4. The compressor 4, the evaporator 1 and the condenser 2 are connected by pipelines to form a circulation loop. Specifically, the output end of the compressor 4 is connected to the condenser 2 through a pipeline, and the input end of the compressor 4 is connected to the evaporator 1 through a pipeline. The evaporator 1 is connected to the condenser 2 through an expansion valve and a pipeline to form a circulation loop for the circulation of the refrigerant.

[0024] The utility model proposes an efficient heat exchange system, which also includes a cabinet 5, an internal cabinet fan 6 and an external cabinet fan 7 arranged in the cabinet 5, and an air partition 8 arranged between the internal cabinet fan 6 and the external cabinet fan 7; the evaporator 1 is located in the cabinet 5 and on the same side as the internal cabinet fan 6; the condenser 2 is located in the cabinet 5 and on the same side as the external cabinet fan 7.

[0025] Both the internal fan 6 and the external fan 7 are centrifugal fans. The internal fan 6 is installed at an elevated angle within the cabinet 5, creating a certain angle difference between the internal fan 6 and the cabinet 5 panel. This creates an angle difference between the return and supply air from the internal fan 6. Due to the density characteristics of hot and cold air, warmer air is distributed above the cabinet 5, while cooler air is distributed below. The internal fan 6 draws hot air from above into the heat exchanger's internal circulation side. After passing through the heat pipe 3, the cooled air is blown parallel to the cabinet 5. This creates an angle difference between the return and supply air, effectively preventing short-circuiting of the hot and cold air.

[0026] Furthermore, an angle a is formed between the upward surface of the fan 6 in the cabinet and the panel of the cabinet 5, 3°≤a≤8°, preferably a=5°.

[0027] Specifically, the specific installation method of the in-cabinet fan 6 and the out-cabinet fan 7 in this embodiment is: the wind partition plate 8 is arranged at an angle, and its upper end close to the inside of the cabinet 5 is provided with an upper bracket 9, and its lower end close to the outside of the cabinet 5 is provided with a lower bracket 10; the in-cabinet fan 6 is installed on the upper bracket 9, and the out-cabinet fan 7 is installed on the lower bracket 10.

[0028] In addition, the external fan 7 in this embodiment is installed at a low angle in the cabinet 5 .

[0029] In this embodiment, the fins a2 in the evaporator 1 and the condenser 2 are window fins, the thickness of the fins a2 is 0.12 mm, and the distance between the fins a2 is 2 mm.

[0030] In addition, the heat pipe 3 and the refrigerant in the refrigerant circulation loop in this embodiment can be controlled independently.

[0031] Based on the refrigerant characteristics of various models, R134a and R410a are widely used. The boiling point of R134A is -14.9°F, while that of R410A is -61.9°F. The pressure of R410A at room temperature is approximately 200 psi, while that of R134A is approximately 70 psi. The refrigerant type and charge can be customized based on the local environment to achieve optimal cooling performance.

[0032] As can be seen from the above, the present invention has the following advantages compared with the prior art:

[0033] 1. The heat pipe 3, evaporator 1, and condenser 2 are integrated into an integrated structure, which improves the integration level and reduces the installation process steps. The return air is dissipated by the parallel fins a2 when passing through the internal circulation side, and then sent into the cabinet 5, which greatly reduces the wind resistance and increases the heat exchange area, thereby improving the heat exchange capacity of the overall heat exchanger.

[0034] 2. The fan 6 inside the cabinet is installed at an upward angle to prevent the return air from the cabinet 5 from being short-circuited with the hot or cold air inside the cabinet 5. The inlet and outlet directions of the ordinary heat pipe 3 heat exchanger are parallel to each other. Due to the limited space inside the cabinet 5, the angle deviation between the return air and the supply air ensures that the low-temperature air after the heat pipe 3 is blown out will not short-circuit with the hot or cold air inside the cabinet 5, thereby improving the circulation and heat dissipation efficiency inside the cabinet 5.

[0035] 3. The heat pipe 3 can be charged with the required refrigerant type and amount according to the environment of the use area; R134a and R410a are generally used.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
