YUHONG GROUP - The Main Role of The Heat Exchanger

According to different working principles and structural forms, heat exchangers can be divided into the following categories:

1. floating head type heat exchanger: by the shell, tube bundle, tube plate, etc., has a simple structure, easy to manufacture, easy to clean, etc., suitable for temperature difference between the larger heat transfer occasions.
2. Fixed tube and plate heat exchanger: composed of shell, tube bundle, tube plate, etc., with high heat transfer efficiency and small temperature difference loss, suitable for high temperature and high pressure heat transfer occasions.
3. U-tube heat exchanger: by the shell, U-shaped tube bundle, tube plate, etc., with a simple structure, easy to clean, not easy to scale, etc., suitable for corrosive media heat transfer occasions.
4. spiral plate heat exchanger: by the shell, spiral channel, tube plate, etc., has a high heat transfer efficiency, small size, light weight, etc., suitable for gas-liquid heat transfer occasions.
5. plate heat exchanger: composed of plates, with high heat transfer efficiency, good corrosion resistance, easy to clean, etc., for low-temperature and low-pressure heat transfer occasions.

The main role of the heat exchanger:

1. improve energy efficiency: heat exchanger can be recycled waste heat reuse, reduce energy waste, improve energy efficiency.
2. reduce production costs: through heat recovery, companies can reduce energy consumption, reduce production costs.
3. to protect the environment: heat exchanger can reduce waste heat emissions, reduce environmental pollution.
4. improve product quality: heat exchanger can accurately control the temperature of the production process, improve product quality.
5. promote scientific and technological progress: heat exchanger research and application of heat transfer, materials science and other related areas of scientific and technological progress.

Application examples of heat exchangers in industrial production:

1. petrochemical industry: in the petroleum refining process, crude oil needs to be heated to promote the reaction. Heat exchanger can effectively heat exchange between crude oil and steam to increase the temperature of crude oil, thereby improving production efficiency. At the same time, the heat exchanger can also react to the waste heat generated by recycling, reducing production costs.
2. the power industry: in thermal power plants, the boiler produces high temperature flue gas needs to be cooled to the appropriate temperature through the heat exchanger and then discharged. In addition, the cooling system of the generator set also needs to use heat exchanger to heat exchange between the coolant and the waste heat generated by the generator, in order to improve the cooling effect and save energy.
3. metallurgical industry: in the steel production process, the molten metal needs to be heated to promote chemical reactions. Heat exchanger can heat exchange the molten metal with molten salt to increase the temperature of the metal, thus improving production efficiency. At the same time, the heat exchanger can also be produced in the production process of waste heat recycling, reduce energy consumption.
4. refrigeration industry: in the air conditioning refrigeration system, the need for refrigerant compression and expansion to achieve the cooling effect. Heat exchanger can be refrigerant and condensate produced by the evaporator for heat exchange, so that the refrigerant temperature is reduced, thereby improving the cooling effect. At the same time, the heat exchanger can also be recycled waste heat generated in the refrigeration process, reducing energy consumption.
