Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to a heat dissipation structure of an air compressor. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. When a screw air compressor is started, the compression rotation of the compression thread causes a large amount of heat to be generated in the threaded compression box, causing the gas in the box to expand, which may damage the compression box.

[0003] Although the existing screw air compressor uses liquid cooling for the rotor and casing during operation, it does not dissipate heat from the external environment of the screw air compressor. In order to achieve effective heat dissipation for the air compressor, users usually install a separate and larger fan outside the air compressor to dissipate heat from the air compressor casing. However, this external fan structure will increase the overall volume of the air compressor, which not only takes up space, but also fails to meet the development needs of product miniaturization.

The active heat dissipation part is composed of the aluminum base plate 1, the U-shaped bend 3, the finned heat exchanger 4 and the negative pressure fan 5. Through the heat conduction of the aluminum base plate 1 and the U-shaped bend 3, with the cooperation of the finned heat exchanger 4 and the negative pressure fan 5, the heat is quickly dissipated to the external environment of the chassis. The auxiliary heat dissipation part is composed of the powerful air knife 7 and the vortex fan 9. The vortex fan 9 provides high-pressure gas, and a high-speed air flow beam is formed through the powerful air knife 7 to generate a strong sweeping force, thereby reducing the surface temperature of the air compressor host 2, which can effectively improve the heat dissipation effect of the air compressor. The overall structure is simple and the volume is small.

[0019] Specifically, a U-shaped groove 11 is provided at the bottom of the aluminum substrate 1 , and the U-shaped bent pipe 3 is embedded in the U-shaped groove 11 .

[0020] In this embodiment, the U-shaped slot 11 is an assembly structure for installing and fixing the U-shaped bent pipe 3 so that the U-shaped bent pipe 3 is completely fitted on the aluminum substrate 1 .

[0021] Specifically, the aluminum substrate 1 is provided with fixing holes 12 around its periphery, and the bottom ends of the vertical rods 6 are embedded in the fixing holes 12 .

[0022] In this embodiment, the fixing hole 12 is an assembly structure, which is mainly used for installing and fixing the vertical pole 6.

[0023] Specifically, a support block 13 is welded to the upper portion of the vertical pole 6 , and the powerful air knife 7 is fixed on the support block 13 .

[0024] In this embodiment, the support block 13 is a supporting structure, which is mainly used for the installation and fixation of the powerful air knife 7. The model of the powerful air knife 7 is WJ-051XX. The principle is that when the high-pressure gas enters the air-cutting high-pressure chamber through the air inlet, the airflow is ejected at an ultra-high speed through a tiny nozzle. At this time, a strong vacuum area is generated behind it. The high-speed ejected airflow pulls a large amount of air around both sides of the air knife to eject forward together, thereby generating a strong blowing force.

[0028] In this embodiment, the main function of the quick connector 14 is to achieve pipeline connection or disconnection in a time-saving and labor-saving manner.

[0029] When in use, the active heat dissipation part is composed of the aluminum substrate 1, the U-shaped bend 3, the finned heat exchanger 4 and the negative pressure fan 5. Through the heat conduction between the aluminum substrate 1 and the U-shaped bend 3, the heat accumulated at the bottom of the air compressor mainframe 2 is quickly dissipated to the external environment of the chassis under the cooperation of the finned heat exchanger 4 and the negative pressure fan 5. The auxiliary heat dissipation part is composed of the powerful air knife 7 and the vortex fan 9. The vortex fan 9 provides high-pressure gas, and forms a high-speed air flow beam through the powerful air knife 7 to generate a strong sweeping force, thereby reducing the surface temperature of the air compressor mainframe 2, which can effectively improve the heat dissipation effect of the air compressor. The overall structure is simple, the volume is small, and the active heat dissipation part and the air compressor The main engine 2 and the auxiliary heat dissipation part are installed together in the chassis of the air compressor, wherein the finned heat exchanger 4 and the negative pressure fan 5 are close to the inner wall of the chassis of the air compressor, and the inner wall of the chassis of the air compressor is provided with heat dissipation holes, and the negative pressure fan 5 corresponds to the position of the heat dissipation holes, so that part of the heat generated by the main engine of the air compressor 2 can be quickly dissipated to the external environment of the chassis, and the vortex fan 9 is also close to the inner wall of the chassis of the air compressor, and its air inlet end extends out of the chassis of the air compressor, so that the outside air can be introduced into the powerful air knife 7, and the negative pressure fan 5, the vortex fan 9 and the solenoid valve 10 are all connected to the control system of the air compressor, and are controlled by the control system of the air compressor.

[0030] In summary, the heat dissipation structure of the air compressor is designed to be heat-dissipating into two parts. The active heat dissipation part is composed of the aluminum substrate 1, the U-shaped bend 3, the finned heat exchanger 4 and the negative pressure fan 5. Through the heat conduction of the aluminum substrate 1 and the U-shaped bend 3, with the cooperation of the finned heat exchanger 4 and the negative pressure fan 5, the heat is quickly dissipated to the external environment of the chassis. The auxiliary heat dissipation part is composed of the powerful air knife 7 and the vortex fan 9. The vortex fan 9 provides high-pressure gas, and forms a high-speed air flow beam through the powerful air knife 7 to generate a strong sweeping force, thereby reducing the surface temperature of the air compressor host 2, which can effectively improve the heat dissipation effect of the air compressor. The overall structure is simple and the volume is small.
