Description

[0002] The intercooling tower is a device used to absorb the heat of hot water in the pipeline and discharge it into the atmosphere to reduce the water temperature. The intercooling tower uses the heat exchange between water and air flow to generate steam. The steam evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer and radiation heat transfer. It is an evaporative heat dissipation device to dissipate the waste heat generated in industry or refrigeration and air conditioning to reduce the water temperature to ensure the normal operation of the system. The device is generally barrel-shaped. The intercooling tower usually includes a tower body, heat dissipation fins and shutters. The heat dissipation fins are used to increase the heat dissipation contact area. The shutters can adjust the blade angle to control the size of the air circulation. Closing the shutters in winter can reduce the circulation of cold air and thus play an anti-freeze role.

[0003] When the existing intercooling tower with antifreeze structure is in use, when the temperature is low in winter, the blades of the shutters may be covered with snow and ice, making it difficult to close the blades, thereby affecting the antifreeze effect of the internal pipes of the intercooling tower.

The blades 502 rotate to close the air inlet 4 to reduce air circulation, so as to achieve heat preservation and antifreeze. The air outlet 2 is provided with a plurality of heat dissipation components 10 at the inner bottom near the air inlet 4. The heat dissipation components 10 all include a mounting seat 1001 fixedly mounted on the inner bottom of the air outlet 2 by bolts. The top of the window frame 501 is fixedly provided with heat dissipation fins 1002, which improves the convenience of heat dissipation and ventilation. The heat dissipation fins 1002 are in the shape of a triangular prism and have a central portion. The heat dissipation fins 1002 are provided with spiral tubes 1003 inside, and the tops of the spiral tubes 1003 are provided with connecting tubes 12. The tops of the connecting tubes 12 are connected to the bottoms of the hot water pipes 3 for diversion, thereby improving the efficiency of hot water heat dissipation. The side walls of the window frame 501 are symmetrically provided with a plurality of clamping blocks 7, and the insides of the clamping blocks 7 are symmetrically clamped with six U-shaped tubes 8.

The other end of the electromagnetic valve 11 is connected to one end of the U-shaped tube 8 through a flange connection. When snow or ice adheres to the surface of the low-temperature blade 502 in winter, the operator starts the electromagnetic valve 11 to transport the hot water in the hot water pipe 3 to the inside of several U-shaped tubes 8 in turn, thereby heating the shutters 5, thereby melting the attached snow and ice, thereby facilitating the rotation and closure of the blades 502, thereby reducing the circulation of cold air, thereby avoiding freezing of cold water in the pipeline, and thus playing an anti-freeze protection role.

[0021] Working principle: When using this intercooling tower with an antifreeze structure, the operator first connects an external power supply, and the hot water pipe 3 transports hot water through a water pump. The hot water first enters the connecting pipe 12 and then is diverted to the inside of the spiral tube 1003.

When snow or ice is attached to the surface of the low-temperature blades 502 in winter, the operator starts the solenoid valve 11 to transport the hot water inside the hot water pipe 3 to the inside of several U-shaped tubes 8 in turn, thereby heating the shutters 5, thereby melting the attached snow and ice, thereby facilitating the rotation and closure of the blades 502, thereby reducing the circulation of cold air, thereby avoiding freezing of cold water in the pipeline, and thus playing an antifreeze protection role.
