[0003] During actual use, the high-temperature and high-pressure gas produced by the air compressor needs to be cooled inside the gas generator. However, after the existing heat dissipation device is added with a noise reduction component, although the noise generated by the air compressor can be reduced, the working environment of the air compressor is generally required to be no higher than 40°C, and the noise reduction component will cause the chamber environment temperature to rise. Due to the reduction in air density and the thermal expansion of internal components, the working performance stability and service life of the air compressor are affected. Utility Model Content

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0028] like Figure 1-Figure 4 As shown, in one embodiment, an exhaust and heat dissipation device includes: a shell 1, in which a cooling plate assembly 2, a radiator 7 and a fan 8 are detachably installed. Through the coordinated action of the cooling plate assembly 2, the radiator 7 and the fan 8, the heat dissipation of the high-temperature fluid of the air compressor is achieved, and at the same time, the operating temperature and working noise of the air compressor are reduced.

[0029] like Figure 1-Figure 4 As shown, in this embodiment, the shell 1 is installed at the heat dissipation exhaust port or air inlet of the air compressor chamber, and the cooling plate assembly 2 is installed inside the shell 1. The material of the cooling plate assembly 2 includes but is not limited to steel, aluminum alloy, copper and other materials with excellent thermal conductivity, which can effectively improve the heat dissipation efficiency and ensure that there will be no deformation or other damage in a high temperature environment.

[0030] Furthermore, the cooling plate assembly 2 includes an upper cold plate 202 and a lower cold plate 201. The upper cold plate 202 is provided with heat dissipation fins 2021 for increasing the heat dissipation surface area and improving the heat dissipation efficiency; the lower cold plate 201 is provided with a serpentine channel 2011 for guiding the high-temperature fluid to flow along a specified path therein, further promoting the heat dissipation.

[0031] In addition, during the assembly process, multiple mounting holes 2015 are provided at the edge of the end surface of the lower cold plate 201, which are used to fasten the upper cold plate 202 to the lower cold plate 201, ensuring that the structure of the cooling plate assembly 2 is stable and not easy to loosen or fall off. In order to prevent leakage of high-temperature fluid and ensure the sealing performance of the cooling plate assembly 2, the lower cold plate 201 is also designed with a sealing groove 2014, which is filled with a sealant or a sealing ring, and is used to seal the joint between the lower cold plate 201 and the upper cold plate 202, which can effectively prevent the leakage of liquid or gas, and can also prevent external impurities from entering, protect the normal operation of the cooling plate assembly 2 and extend its service life.

[0032] Specifically, a cold plate air outlet 2012 and a cold plate air inlet 2013 are respectively arranged at the diagonals of the lower cold plate 201, and the serpentine channel 2011 connects the cold plate air outlet 2012 and the cold plate air inlet 2013 at both ends. A cold plate air outlet interface 4 and a cold plate air inlet interface 3 are respectively arranged on the outer side of the lower cold plate 201, so that high-temperature gas enters from the cold plate air inlet interface 3 through the cold plate air inlet 2013, obtains preliminary heat dissipation in the serpentine channel 2011 of the cooling plate assembly 2, and then flows out from the cold plate air outlet 4 through the cold plate air outlet 2012.

[0033] like Figure 1-Figure 4 As shown, in this embodiment, the radiator 7 is installed above the cooling plate assembly 2. The radiator 7 is selected from any one of a heat dissipation coil, a fin radiator 7 and a heat exchanger.

[0034] Furthermore, a radiator air inlet interface 5 and a radiator air outlet interface 6 are respectively provided on both sides of the radiator 7, and the radiator air inlet interface 5 is connected to the cold plate air outlet interface 4 through a fluid pipeline. When the high-temperature gas flows out from the cold plate air outlet 2012, it enters the radiator air inlet interface 5 through the fluid pipeline. Inside the radiator 7, the high-temperature gas exchanges heat with the heat dissipation medium of the radiator 7, thereby transferring heat to the radiator 7. After the heat dissipation process, the cooling medium is cooled inside the radiator 7 and forms low-temperature gas.

[0035] like Figure 1-Figure 4 As shown, in this embodiment, fans 8 are installed on both sides of the middle of the housing 1, and at least one group of fans 8 is provided. In order to effectively dissipate heat, the air outlets of the fans 8 and the radiator 7 are staggered to ensure good air circulation and heat dissipation effects. The diameter of the air inlet of the fan 8 will not be larger than the diameter of the fan 8 itself, which helps to ensure that the fan 8 can fully inhale external air and improve the heat dissipation efficiency.

[0036] Working principle: The high-temperature gas first enters the serpentine channel 2011 of the cooling plate assembly 2 through the cold plate air inlet interface 3, which can increase the contact area between the gas and the cooling plate, thereby achieving a preliminary heat dissipation effect. The high-temperature gas passing through the serpentine channel 2011 flows out smoothly through the cold plate air outlet interface 4 and enters the fluid pipeline. Next, the high-temperature gas enters the radiator 7 from the air inlet of the radiator 7 through the fluid pipeline. The radiator 7 is located at the air inlet. Inside the radiator 7, the high-temperature gas and the heat dissipation medium of the radiator 7 perform secondary heat exchange to further reduce the temperature of the gas.

[0037] Through the coordinated use of the cooling plate assembly 2 and the radiator 7, the high-temperature fluid undergoes two cooling processes, thereby effectively achieving the heat dissipation of the high-temperature fluid; the air inlets of the fan 8 and the radiator 7 are staggered, and the air inlet diameter is small, so that the internal noise is blocked to a certain extent, thereby achieving the purpose of lowering the working environment temperature of the air compressor and reducing the operating noise.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
