The working principle of the refrigerant circulation cooling system: The refrigerant liquid is throttled and depressurized through a capillary tube, and flows into the evaporator; Vaporization occurs inside the evaporator, absorbing the heat of the cooled water in the external circulation cooling system of the water circuit, and transforming it into high-temperature mortgaged refrigerant steam that is sucked into the compressor; After being compressed into high-temperature and high-pressure steam in the compressor, it is discharged into the condenser.
In the condenser, the refrigerant releases heat to the cooling medium - air, and after condensation, it injects a high-pressure and low-temperature liquid into a capillary tube. Through capillary tubes, it enters the evaporator again for heat absorption and vaporization, achieving the purpose of circulating refrigeration.
The working principle of the water circuit external circulation cooling system: water exchanges energy with the refrigerant in the evaporator in the water tank; After being cooled, it flows through a water tank, filter, and water pump to a heat exchanger in the water circulation cooling system. In the heat exchanger, it exchanges energy with the internal circulating water, absorbs its heat, and then returns to the water tank to maintain the internal circulating water within a certain temperature range.
The working principle of the water circuit internal circulation cooling system: The internal circulation water and the external circulation water exchange energy in the heat exchanger. After being cooled, they return to the water tank, pass through the filter and water pump, and pass through the laser cavity, taking away the heat in the laser cavity. The laser is cooled, and when the temperature rises, it flows back to the heat exchanger for energy exchange with the external circulation water.
