[0020] With such a design, the air inlet 1 can be connected to the heat exchange medium to be cooled and heat exchanged, and the heat exchange medium to be cooled and heat exchanged enters the air inlet box 2 through the air inlet 1, and is then transported to the cooler support body 5. At this time, the heat exchange medium exchanges heat with the cooler body 6 in the cooler support body 5, and the cooler body 6 is used to cool the heat exchange medium to reduce the temperature of the heat exchange medium. The cooled heat exchange medium is discharged through the air outlet box 4 and the air outlet 10 for easy use.

[0021] The overall structure of the cooler body 6 includes a cooling pipe that is arranged reciprocatingly, and a heat dissipation fin is fixedly installed on the cooling pipe. The heat dissipation fin is used to increase the heat exchange area between the cooling pipe and the heat exchange medium. A coolant inlet 8 and a coolant outlet 9 are respectively provided at both ends of the cooling pipe; the automatic control valve 14 is fixedly installed at the coolant inlet 8.

[0022] The cooling liquid inlet 8 and the cooling liquid outlet 9 are respectively connected to an external cooling water source. The external cooling water source delivers cooling water to the cooler body 6 through the cooling liquid inlet 8, and then flows back to the external cooling water source through the cooling liquid outlet 9 to achieve a circulating flow.

[0023] The overall structure of the air inlet box 2 is a right-angled trapezoidal box body, the upper end face of the air inlet box 2 is a plane, the lower side face and the front side face are inclined faces, the rear side face of the air inlet box 2 is a plane, and the inner cavity of the air inlet box 2 is connected to the inner cavity of the cooler support body 5.

[0024] The air inlet 1 is arranged obliquely on the upper end surface of the air inlet box 2, and the inclination angle between the air inlet 1 and the upper end surface of the air inlet box 2 is 45°.

[0025] A drain channel 7 is provided on one side of the cooler support body 5 and close to the inner bottom surface of the cooler support body 5 , and the condensed liquid condensed in the cooler support body 5 is discharged through the drain channel 7 .

[0026] The overall structure of the air outlet box 4 is a right-angled trapezoidal box body, the upper end surface of the air outlet box 4 is a plane, the front side surface, the rear side surface and the lower side surface of the air outlet box 4 are all inclined surfaces, and the side surface of the air outlet box 4 away from the cooler support body 5 is also a plane.

[0027] The air outlet 10 is provided on a side plane of the air outlet box 4 away from the cooler support body 5 , and the air outlet 10 is communicated with the inner cavity of the air outlet box 4 , and the inner cavity of the air outlet box 4 is communicated with the inner cavity of the cooler support body 5 .

[0028] With this design, when the hot gas needs to be cooled, the coolant inlet 8 and the coolant outlet 9 are first connected to the external cooling water source respectively, and the external cooling water source delivers cooling water through the coolant inlet 8 to the cooler body 6, and then flows back to the external cooling water source through the coolant outlet 9 to achieve a circulating flow.

[0029] At the same time, the hot gas that needs to be cooled is transported to the air inlet box 2 through the air inlet 1, and then transported to the inner cavity of the cooler support body 5 through the air inlet box 2. At this time, the hot gas exchanges heat with the cooler body 6 to cool the hot gas. The cooled gas enters the air outlet box 4 and is then discharged from the air outlet 10, thereby achieving the effect of cooling and lowering the temperature of the hot gas.

[0030] In this embodiment, the intercooler of the magnetic levitation air compressor can also cool down the liquid. The liquid that needs to be cooled down is transported to the air inlet box 2 through the air inlet 1, and then transported to the inner cavity of the cooler support body 5 through the air inlet box 2. At this time, the liquid exchanges heat with the cooler body 6 to cool down the liquid. The cooled liquid enters the air outlet box 4 and is then discharged from the air outlet 10, thereby cooling and lowering the temperature of the liquid that needs to be cooled down, which is convenient to use.

[0031] In this embodiment, a cooler upper groove 11 is opened on the cooler body 6, and the cooler upper groove 11 can provide more surface area to achieve the purpose of rapid heat dissipation.

[0032] The drain channel 7 is connected in series with a switch valve, which is used to open or close the drain channel 7. When the hot air is cooled in the cooler support body 5, condensed water will be generated. The condensed water will remain in the inner cavity of the cooler support body 5, thereby reducing the cooling effect of the cooler body 6 on the hot air. At this time, the switch valve can be operated to open the drain channel 7, and the condensed water can be discharged through the drain channel 7, which is convenient to use.

[0033] In this embodiment, the automatic control valve 14 is installed at the coolant inlet 8 , and the flow rate and flow velocity of the cooling water in the cooler body 6 can be adjusted by adjusting the opening of the automatic control valve 14 .

[0034] The control system is used to adjust the opening of the automatic control valve 14, and further to adjust the flow rate and flow velocity of the cooling water in the cooler body 6, so as to achieve the purpose of controlling the cooling effect.

[0035] The control system comprises a main trunk 15 , three regulating circuits 16 are connected in parallel at the middle of the main trunk 15 , and a main switch 17 is connected in series at the front side of the main trunk 15 close to the regulating circuits 16 .

[0036] The three regulating circuits 16 are sequentially connected in series with regulating switches 18 and resistors 19 along the conducting direction. The three regulating switches 18 are arranged in parallel. The three resistors 19 have the same resistance value and are also arranged in parallel.

[0037] In this embodiment, the total circuit voltage on the main trunk 15 is fixed, and the main switch 17 is closed to supply power to the three regulating circuits 16. At this time, when the regulating switch 18 on one of the regulating circuits 16 is closed, the total circuit resistance value is maximum, and the current is minimum when the resistance value is maximum. At this time, the opening of the automatic control valve 14 is in the first gear; when the regulating switches 18 on two regulating circuits 16 are closed, the resistance value is relatively reduced and the current is increased. At this time, the opening of the automatic control valve 14 is in the second gear; when the regulating switches 18 on three regulating circuits 16 are closed, the resistance value reaches the minimum value and the current is also maximum. At this time, the opening of the automatic control valve 14 is maximum, the flow rate reaches maximum, and the cooling effect is best.

[0038] In this embodiment, the three resistors 19 are arranged in parallel, and the total resistance value will decrease; the voltage is fixed, and when one is closed, the resistance value is the largest and the current is the smallest.

[0039] The current values ​​corresponding to different gears will be fed back to the PLC, and the motor will be controlled through the program to control the opening of the automatic control valve 14. Its application scenario is mainly the heat dissipation problem of the air compressor caused by the customer's gas consumption. The cooling water flow of the intercooler can be controlled by the adjustment switch 18 in the control system according to the customer's external gas consumption demand to achieve an ideal heat dissipation effect.

[0040] For those skilled in the art, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
