Description

TECHNICAL FIELD

[0001] The utility model belongs to the cold -drying machine auxiliary equipment technical field especially a pre -cooler for cold -drying machine. BACKGROUND

[0002] The cold -drying machine is the short name of refrigeration dryer, and the compressed air temperature is reduced to the dew point temperature in the range of 2-10 DEG C by using the heat exchange of refrigerant and compressed air. The pre-cooler refers to the heat exchanger or evaporative cooler that reduces the temperature of the working medium before it is compressed. The existing pre-cooler for cold -drying machine directly exports the cooling liquid through the setting electromagnetic valve during cold start, reduces the working time of the pre-cooler in the cold start stage. Because the pre-cooler needs to be disassembled, repaired and replaced after a long time, the overall structure of the existing equipment is integrally formed, which is not convenient to disassemble and reduces the practicability of the device.

[0003] After searching, for example, (authorized announcement number CN219103383U) a pre-cooler for refrigeration system, including shell, pre-cooler main part, liquid inlet pipe, liquid outlet pipe, temperature sensor, electromagnetic valve, check valve A, check valve B, controller and speed regulation device, pre-cooler main part is fixed in the shell, liquid inlet pipe is fixed on one side of pre-cooler main part, and temperature sensor, electromagnetic valve are arranged on liquid inlet pipe, electromagnetic valve is arranged behind temperature sensor, liquid outlet pipe is fixedly connected with pre-cooler main part, check valve A is fixed on liquid outlet pipe, electromagnetic valve is connected with check valve B, check valve B is fixedly connected with liquid outlet pipe, controller is fixed in the inner side of shell, controller is electrically connected with temperature sensor, electromagnetic valve, speed regulation device, and speed regulation device is fixed in the shell. The device solves the problem that the cold start stage still works when the existing equipment is used, but the device is integrally formed in the overall structure, which is inconvenient to disassemble, cannot repair and replace the internal components of the pre-cooler, and reduces the practicability of the device.
