Introduction of cooler:

The cooler is a type of heat exchanger used to cool the fluid. Usually water or air is used as a coolant to remove heat. There are wall cooler, spray cooler, jacket cooler and snake tube cooler, etc. The main object of the cooler is the interwall type, mixed type and regenerative type exchanger. The working principle, heat transfer calculation, structure calculation, flow resistance calculation and design program of the cooler.

Function of cooler:

The cooler, a Condenser, is a condenser of the refrigeration system, belonging to a condenser, which can convert the gas or vapor into liquid and transmit the heat in the tube to the air near the tube in a rapid manner. The working process of the cooler is an exothermic process, so the temperature of the cooler is higher.

After absorbing the heat of the cooled object in the evaporator, the liquid refrigerant vaporizes into low-temperature and low-pressure steam, is inhaled by the compressor, compressed into high-pressure and high-temperature steam and enters the cooler. In the cooler, it releases heat to the cooling medium (water or air), condenses into high-pressure liquid, is throttled by the throttle valve for low-pressure and low-temperature refrigerant, and enters the evaporator again to absorb heat and vaporize. To achieve the purpose of circulating refrigeration. In this way, the refrigerant in the system through evaporation, compression, condensation, throttling four basic processes to complete a refrigeration cycle.

Power plants use many coolers to condense steam from turbines. Coolers are used in refrigeration plants to condense cooling vapors such as ammonia and freon. A cooler used in the petrochemical industry to condense hydrocarbons and other chemical vapors. In the distillation process, the device that converts vapor into liquid is also called a cooler. All coolers operate by taking away the heat from gases or vapors.

Type:

1. Steam cooler:

This kind of condensation is often used to condense the secondary steam of the final effect of the multi-effect evaporator to ensure the vacuum of the final effect evaporator.

2, boiler cooler:

Boiler cooler, also known as flue gas cooler, boiler using flue gas cooler, can effectively save production costs, reduce the exhaust temperature of the boiler, improve the thermal efficiency of the boiler. Make the boiler operation in line with the national standards of energy conservation and emission reduction.

The above is a small series on the role of the cooler and brief knowledge sharing, you must be the most common heat machine is the mobile phone, we all know that when the mobile phone is hot, its shell will become very hot, even sometimes hot. Different machines will have some heat dissipation functions. These heat dissipation devices have the same function as the cooler, which plays a very important role in the use of the machine. The introduction of the cooler is over. I hope I can help my friends who need help.
