In our country, common refrigeration devices include air-conditioning refrigeration devices, freezer devices, experimental refrigeration devices, freezing storage devices, industrial and engineering refrigeration devices, etc. Traditional refrigeration devices have complex structures, high prices, large volumes and weights, and high sealing requirements. Compared with the vortex tube of the new refrigeration method, it has "simple structure, small volume, low price, small weight, low energy consumption" and so on. Advantages, known as "the new air conditioning system with revolutionary changes, is undoubtedly not a better choice in certain fields of refrigeration applications."

Vortex tube

The basic principle of the vortex tube is that compressed air enters the vortex chamber along the tangential direction at a very high speed. After the gas forms a vortex, it rotates forward. The gas along the vortex tube wall rubs against the tube wall, and the temperature will rise rapidly. Its temperature is higher than The temperature of the compressed gas at the inlet; part of it returns along the center line, forming a backflow. This part of the gas goes in the opposite direction to the vortex close to the tube wall. The continuous heat exchange causes its temperature to gradually decrease, forming a cold air flow. Chassis cooler

The United States has long used vortex tubes to develop automotive air conditioning systems. Since it is very convenient to connect an air compressor to a car engine, the compressed air generated by the air compressor can be injected into the air storage tank through the heat dissipation pipe, and then connected to the nozzle of the vortex tube along the pipe. The hot and cold air flows after the splitting pass through the reversing valve. They are respectively inserted into the cab, and the driver operates the valve for air conditioning. According to reports, the United States has long used air conditioners in cars to replace traditional compression air conditioners, and the cost is only 1/5 to 1/10 of traditional air conditioners. Super air knife
