[0002] Compressors are indispensable equipment in many industrial fields and daily life, such as refrigeration equipment, air conditioning systems, and automobile engines. With the continuous advancement of technology, the requirements for compressor performance are also increasing, especially in terms of cooling efficiency and service life. The compressor cooling devices widely used on the market mainly rely on traditional air cooling or water cooling to dissipate heat. However, these methods have certain limitations in practical applications. For example, the air cooling method has limited effect in extremely high temperature environments, resulting in low heat dissipation efficiency; while the water cooling method is limited by the complexity of the water source and the cooling system, and most of them are local cooling of the compressor, which will lead to uneven cooling and low cooling efficiency, which can easily cause the compressor to overheat and affect its working stability and service life.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses an oil-free compressor cooling device. Figure 1-Figure 3, including a cooling box 1, a heat conducting plate 2 is fixedly installed at the bottom of the cooling box 1, the heat conducting plate 2 is a special aluminum plate with high thermal conductivity and high strength, which can play a role of rapid heat conduction, and a group of auxiliary radiators 10 are connected to the side wall of the cooling box 1 by bolts, and the auxiliary radiator 10 is arranged in a ring shape, and the auxiliary radiator 10 surrounds the outer wall of the oil-free compressor, which can increase the contact area and thus improve the heat conduction efficiency, and water inlets 11 are provided inside at both ends of the cooling box 1, and a water outlet 12 is provided on one side of the water inlet 11, and the water inlet 11 and the water outlet 12 are both threadedly connected to the outside with sealing covers, and the sealing covers can be opened to connect the external cooling pump through the water inlet 11.

[0020] A cooling chamber 13 is provided inside the cooling box 1, and a serpentine cooling water pipe 14 is installed inside the cooling chamber 13. An external cooling pump can be connected through the serpentine cooling water pipe 14 to transport the cooling medium. A group of through holes 15 are symmetrically provided on the side wall of the cooling box 1 to transfer the cooling medium.

[0021] Combination Figure 2 As shown, cooling air boxes 3 are detachably installed on both sides of the top of the cooling box 1, and reinforcing plates 6 for support are fixed at the corners of the inner wall of the cooling air box 3 to improve the overall strength. A cooling fan 4 is installed in the cooling air box 3. The cooling fan 4 adopts a special low-noise, large-air-volume fan. By optimizing the shape and angle of the fan blades, the noise generation is reduced while the heat dissipation efficiency is improved. A group of radiators 5 are fixed on the back wall of the cooling air box 3. The radiator 5 is made of high thermal conductivity material. The heat dissipation efficiency is improved by increasing the heat dissipation area and changing the arrangement of the heat sink fins. A group of connecting parts 9 are connected between the inner walls of each two adjacent radiators 5, and a circulating water pipe 7 is provided between each two adjacent radiators 5, and the circulating water pipe 7 is fixed to the inner wall of the radiator 5 to ensure the strength of the structure.

[0022] In addition, both ends of the circulating water pipe 7 are fixed with connecting pipes 8 in an integrated structure. One end of the connecting pipe 8 extends into the cooling box 1 and is fixedly connected to the side wall of the serpentine cooling water pipe 14. Therefore, the cooling medium inside the serpentine cooling water pipe 14 can be recycled, further improving the overall cooling efficiency.

[0023] The implementation principle of an oil-free compressor cooling device in an embodiment of the present application is as follows: when in use, the auxiliary radiator 10 is installed on the outside of the oil-free compressor, and the cooling box 1 is simultaneously mounted on the top of the oil-free compressor. At this time, the heat conducting plate 2 is tightly fitted with its outer wall. After the oil-free compressor has been working for a long time, the sealing cover can be opened, and the external cooling pump and the water pipe are connected through the water inlet 11. The cooling medium is transported to the inside of the serpentine cooling water pipe 14 through the cooling pump. At this time, the heat conducting plate 2 is in contact with the oil-free compressor, absorbs the heat generated by the oil-free compressor, and transfers it to the cooling chamber 13 for cooling. The cooling medium that absorbs the heat will be transported to the circulating water pipe 7 through the connecting pipe 8. Since the radiator 5 is made of high thermal conductivity material, the heat dissipation efficiency is improved by increasing the heat dissipation area and changing the arrangement of the heat sink fins. The radiator 5 is in close contact with the circulating water pipe 7 to ensure that the heat can be quickly transferred. Then, the cooling fan 4 inside the cooling air box 3 is started to work, forcing the external air to flow through the radiator 5, accelerating the convection heat dissipation of the heat, and the heat in the circulating water pipe 7 can be quickly dissipated to the external environment, thereby improving the heat dissipation efficiency.
