Working principle of the refrigerant circulating cooling system: the refrigerant liquid flows into the evaporator after throttling and depressurization through the capillary tube; Vaporize in the evaporator, absorb the heat of the cooled water in the external circulation cooling system of the water path, and turn into the refrigerant steam mortgaged by the high temperature, which is sucked into the compressor; The steam compressed into high temperature and high pressure in the compressor is discharged into the condenser.
Working principle of water circulating cooling system of CO2 laser cutting machine
In the condenser, the refrigerant releases heat to the cooling medium - air. After condensation, it injects high-pressure and low-temperature liquid into the capillary. It enters the evaporator again through the capillary to absorb heat and vaporize, so as to achieve the purpose of circulating refrigeration.
Working principle of water circuit external circulation cooling system: water exchanges energy with refrigerant in evaporator in water tank; After being cooled, it passes through the water tank, filter and water pump to the heat exchanger in the water circuit internal circulation cooling system, where it exchanges energy with the internal circulation water, absorbs its heat, and then returns to the water tank to keep the internal circulation water unchanged within a certain temperature range.
Working principle of water circulating cooling system of CO2 laser cutting machine
Working principle of the internal circulation cooling system in the waterway: the internal circulation water and the external circulation water exchange energy in the heat exchanger, return to the water tank after being cooled, and then pass through the filter and water pump, flow through the laser cavity, take away the heat in the laser cavity, cool the laser, rise in temperature, and then flow back to the heat exchanger to exchange energy with the external circulation water.
