[0001] The utility model relates to the technical field of heat exchangers, in particular to a heat pipe heat exchanger. Background Technique

[0002] Heat pipe technology makes full use of the principle of heat conduction and the rapid heat transfer property of the refrigerating medium. Through the heat pipe, the heat of the heating object is quickly transferred outside the heat source. Its heat conduction ability exceeds that of any known metal. Using heat pipe technology to make radiators gets rid of the single heat dissipation mode that solely relies on high-air-volume motors to obtain better heat dissipation effects. Using heat pipe technology enables the heat exchanger to obtain satisfactory effects even with low-speed and low-air-volume motors.

[0003] However, the traditional heat dissipation method mainly relies on high-air-volume motors, with more energy consumption and operating costs, and the heat dissipation mode is relatively single. When the heat dissipation demand is large or the ambient temperature is high, it is difficult to meet the effective heat dissipation requirements. Therefore, a heat pipe heat exchanger is proposed to solve the above problems. Summary of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 , Figure 2 and Figure 3, an embodiment provided by the present utility model: a heat pipe heat exchanger, including a sheet metal housing 3, a heat dissipation fan 4 is fixedly connected to the outside of the sheet metal housing 3, a parallel flow heat exchanger 2 is fixedly connected to the outside of the sheet metal housing 3, the parallel flow heat exchanger 2 includes a parallel flow heat exchanger core 204, a refrigerant filling valve 203 is fixedly connected to the top of the parallel flow heat exchanger core 204, the outside of the parallel flow heat exchanger core 204 is fixedly connected to the outside of the sheet metal housing 3, an evaporation pipe 201 is fixedly connected to the outside of the parallel flow heat exchanger core 204, a condensation return pipe 202 is fixedly connected to the outside of the parallel flow heat exchanger core 204, and the other end of the condensation return pipe 202 is fixedly connected to a liquid cooling plate 1; the liquid cooling plate 1 includes a second joint 108, one end of the second joint 108 is fixedly connected to the other end of the condensation return pipe 202, the other end of the second joint 108 is slidably connected to a second cover plate 104, a first cover plate 103 is fixedly connected to the outside of the second cover plate 104, a substrate 101 is fixedly connected to the inner wall of the first cover plate 103, a plurality of partition plates 102 are slidably connected to the outside of the substrate 101, and a plurality of mounting brackets 109 are fixedly connected to the outside of the first cover plate 103; a plurality of first joints 107 are slidably connected to the other side of the first cover plate 103, and the other end of every three first joints 107 is fixedly connected to a first liquid inlet and outlet assembly 105, and one end of the first liquid inlet and outlet assembly 105 is fixedly connected to a second liquid inlet and outlet assembly 106.

[0031] Further, the hot fluid enters the liquid flow channel through one of the second liquid inlet and outlet assemblies 106 and the first liquid inlet and outlet assembly 105, that is, in the closed heat absorption area formed by the substrate 101 and the first cover plate 103. Then, the heat released by the hot fluid is transferred to the refrigerant area formed by the substrate 101 and the second cover plate 104 through the substrate 101. The refrigerant absorbs heat and evaporates to form steam. Then, the steam enters the parallel flow heat exchanger 2 through the evaporation pipe 201. Then, heat is dissipated through the parallel flow heat exchanger core 204. The heat dissipation fan 4 forces convective heat transfer to improve the heat transfer efficiency, so that the gaseous refrigerant is cooled into a liquid state. At this time, the cold fluid flows back to the closed inner cavity formed by the substrate 101 and the second cover plate 104 through the condensation return pipe 202. At this time, the hot fluid inside the liquid cooling plate 1 is efficiently heat-exchanged and flows out from the other first liquid inlet and outlet assembly 105 and the second liquid inlet and outlet assembly 106, so as to achieve the purpose of circulating heat exchange.

[0032] Refer to Figure 1 , Figure 4 and Figure 5 , the mounting bracket 109 is made of aluminum, and the mounting bracket 109 and the first cover plate 103 are integrally designed; both the first liquid inlet and outlet assembly 105 and the second liquid inlet and outlet assembly 106 are made of copper, and the second liquid inlet and outlet assembly 106 and the first joint 107 are welded by gas welding; the first liquid inlet and outlet assembly 105 and the second liquid inlet and outlet assembly 106 are symmetrically distributed about the center; the side of the substrate 101 close to the partition plate 102 is a toothed surface; the substrate 101, the first cover plate 103 and the second cover plate 104 are all fully enclosed areas.

[0033] Furthermore, the density of aluminum products is relatively small, which can reduce the overall weight. To a certain extent, its thermal conductivity can also play a certain auxiliary role in the heat transfer process of the heat exchanger system, helping to evenly distribute or dissipate heat. At the same time, aluminum is easy to weld and process, and the one-piece welding design can ensure the firmness and stability of the connection between the mounting bracket 109 and the cover plate 103; copper has excellent thermal conductivity and can transfer heat efficiently, reducing heat loss during the transmission process and improving the heat exchange efficiency. The inlet and outlet liquid assembly 2 106 and the joint 1 107 are welded by gas welding. Copper has good fluidity at high temperatures and is easy to form a firm connection with the joint 1 107, ensuring good sealing at the connection part and preventing the leakage of heat exchange medium; the central symmetric distribution helps to balance the pressure during the inlet and outlet liquid process, reducing the leakage risk and equipment damage caused by excessive local pressure difference, and making the system operation more stable; one side of the substrate 101 adopts a toothed surface to facilitate the insertion of the partition plate 102 to divide the liquid flow channel, so as to better transfer heat; the substrate 101 and the cover plate 1 103 form a closed heat absorption area to reduce heat loss, and the substrate 101 and the cover plate 2 104 form a closed refrigerant area to absorb heat through the refrigerant, and then form steam.

[0034] Working principle: The hot fluid enters one side of the toothed surface of the substrate 101 through one of the inlet and outlet liquid assemblies 2 106 and the inlet and outlet liquid assembly 1 105. Then, the heat of the hot fluid is released and transferred into the substrate 101, and then the heat is transferred to the refrigerant in the inner cavity on the other side of the substrate 101. The refrigerant absorbs heat and evaporates to form steam. Then, the steam enters the parallel flow heat exchanger 2 through the evaporation pipeline 201 and dissipates heat through the parallel flow heat exchanger core 204. The cooling fan 4 forces convective heat transfer, so that the gaseous refrigerant is cooled into a liquid state and flows back to the closed inner cavity formed by the substrate 101 and the cover plate 2 104 through the condensation return pipeline 202. The hot fluid inside the liquid cooling plate 1 is efficiently heat-exchanged and flows out from the other inlet and outlet liquid assembly 1 105 and the inlet and outlet liquid assembly 2 106, and so on for cyclic heat exchange.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
