Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange for air compressors, in particular to a heat exchange mechanism for air compressors. Background Art

[0002] An air compressor is a device used to compress gas. An air compressor is similar to a water pump. Most air compressors are reciprocating piston type, rotary vane or rotary screw. Centrifugal compressors are very large applications. When an air compressor works, it generates heat, so a heat exchanger is needed to transfer part of the heat of the hot fluid to the cold fluid, also known as a heat exchanger.

[0003] The existing Chinese utility model patent "A heat exchange mechanism for an air compressor" with application number 202222239922.0 discloses that "under the action of the heat dissipation motor, the heat dissipation blades are driven to rotate synchronously, so that air enters the air compressor casing through the outer port of the sleeve. The temperature of the air decreases when it flows through the cooling water pipe, and the cold air enters the air compressor casing for heat dissipation. When the heat dissipation blades rotate, a lot of noise will be generated, and the noise is absorbed by the sound-absorbing sponge columns embedded in the inner ring surface of the sleeve, thereby improving the heat dissipation effect of the air compressor." However, when air flows through the cooling water pipe, condensed water will condense on the surface of the cooling water pipe surrounding the inner wall of the sleeve, and the condensed water drips and gathers between adjacent water pipes, which is inconvenient to handle.

Among them, the wind direction adjustment component adjusts the wind direction of the cold air blowing into the shell, so that the cold air quickly fills the inside of the shell, improving the heat dissipation and cooling rate and effect.

[0032] Specifically, Figure 1 As shown, the heat exchange assembly 2 includes a connecting pipe 16, a partition 6, and a ventilation pipe 7.

Since the ventilation pipe 7 is in direct contact with the coolant, even if condensed water is generated on the surface of the ventilation pipe 7, it is directly integrated into the coolant, and there is no problem of handling condensed water. When the cooling fan 5 is working, the air outside the shell is cooled by the ventilation pipe 7 and the cold air is blown into the shell to dissipate heat and cool the shell.

[0033] Specifically, Figure 4 As shown, the cooling device 3 includes a coolant tank 17, a cooling pump 18, a liquid inlet pipe 19 and a circulation pipe 20.

Add a proper amount of coolant to the coolant tank 10, start the cooling pump 18, and extract the coolant under the action of the cooling pump 9, enter the cooling cavity through the cooling pump 18 and the liquid inlet pipe 19, and then return to the coolant tank 10 through the circulation pipe 20. During the coolant circulation process, the coolant in the cooling cavity can always contact the ventilation pipe 7.

[0034] Specifically, Figure 3 and Figure 4As shown, the wind direction adjustment assembly includes an installation box 8, a T-bar 9, a spring 10, a hose 11, an eccentric wheel 12, a transmission shaft 13, a driven gear 14, and a driving gear 15. The installation box 8 is fixedly sleeved on the outside of the sleeve 4 and the connecting pipe 16. The driving gear 15 is fixedly sleeved on the motor shaft of the cooling fan 5. There is a rotation space between the sleeve 4 and the connecting pipe 16 to accommodate the movement of the driving gear 15. Two sets of transmission shafts 13 are rotatably installed on the installation box 8. The transmission shaft 13 is fixedly connected to a driven gear 14 meshing with the driving gear 15. The transmission shaft 13 extends into one end of the air compressor housing 1 The fixed sleeve is provided with an eccentric wheel 12, the hose 11 is fixedly connected to the other end of the sleeve 4, the outer wall of the eccentric wheel 12 is tangent to the outer wall of the hose 11, one end of the T-bar 9 is fixedly connected to the inner side of the installation box 8, the other end of the T-bar 9 is fixedly connected to a plurality of springs 10, the springs 10 extend in the radial direction of the sleeve 4, the free ends of the springs 10 are fixedly connected to the hose 11, two groups of transmission shafts 13 and T-bars 9 are arranged around the outside of the hose 11, the two groups of transmission shafts 13 are arranged adjacently, the two groups of T-bars 9 are arranged adjacently, and the adjacent transmission shafts 13 or T-bars 9 or the transmission shafts 13 and T-bars 9 are spaced 90° apart. When the cooling fan 5 is working, the cooling fan motor shaft drives the driving gear 15 to rotate synchronously, the driving gear 15 drives the two driven gears 14 to drive the transmission shaft 13 to rotate, and the transmission shaft 13 drives the eccentric wheel 12 to rotate. Under the elastic action of the spring 10, the hose 11 swings back and forth, changes the direction of the cold air blowing out, and allows the cold air to quickly cover the shell, thereby improving the heat dissipation and cooling rate and effect.

[0035] Specifically, Figure 3 and Figure 5 As shown, convex rings 21 are axially protruded at both ends of the driving gear 15, and grooves for accommodating the convex rings 21 are provided at the ends of the sleeve 4 and the connecting tube 16. The contact surface between the convex ring 21 and the groove is a smooth surface, which supports the driving gear 15.

The coolant enters the cooling chamber through the cooling pump 18 and the liquid inlet pipe 19, and then flows back to the coolant tank 10 through the circulation pipe 20. During the coolant circulation process, the coolant in the cooling chamber can always be in contact with the ventilation pipe 7. Afterwards, when the cooling fan 5 is working, the air outside the shell is cooled through the ventilation pipe 7 and the cold air is blown into the shell. At the same time, the cooling fan motor shaft drives the driving gear 15 to rotate synchronously, and the driving gear 15 drives the two driven gears 14 to drive the transmission shaft 13 to rotate, and the transmission shaft 13 drives the eccentric wheel 12 to rotate. Under the elastic action of the spring 10, the hose 11 swings back and forth and left and right, changing the direction of the cold air blowing out, so that the cold air can quickly cover the shell, thereby improving the heat dissipation and cooling rate and effect.
