Fin Radiator apply for Computer Serve zoom


Finned radiator should not be easy to be corroded and damaged, where fins are installed on the heat exchange tube to increase the cooling area of the heat exchanger, can be concluded as "finned tube radiator". Finned tube radiator according to the structure of the fin can be divided into wound chip type; String type; Welding plate; Rolled plate. The commonly used material is steel; Stainless steel; Aluminum, etc. Finned radiator is widely used in steel and aluminum finned tube (around the plate type steel-aluminum composite finned tube, rolled plate type steel-aluminum composite finned tube) it makes use of the steel pipe pressure resistance and thermal conductivity of aluminum, zhejiang video card water-cooled radiator in the machine composite. The contact thermal resistance is almost zero at 210℃. Steel-aluminum composite tube radiator has irreplaceable advantages over other types of finned tube radiator. Finned tube radiators are generally used for heating or cooling air, and have the characteristics of compact structure and large unit heat exchange area. The heat resistance provided by the radiator manufacturer is generally measured by a square heat source of the radiator. Usually, a square heat source with a size of 24 mm x 24 mm (fixed heat consumption) is connected to the center of the bottom surface of the radiator base plate, and then the temperature difference is measured. The heat resistance of the radiator can be calculated by formula 1.


Some models will be equipped with a separate transmission oil radiator at the front end of the engine compartment, and also need a radiator fan to help heat dissipation. In the process of driving, the engine will have airflow blowing from front to back to the radiator radiator, condenser and other radiators, which itself has the function of helping the radiator ventilation and heat dissipation. Equipped with radiator fan mainly has the following two functions: in the process of vehicle driving, there will be air flow through the radiator, but due to the engine block, will make the air flow through the radiator is chaotic, can not achieve better heat dissipation effect, at this time you need the assistance of the radiator fan. When the heat dissipation condition is reached, the fan rotates and absorbs the air from front to back. At this time, the wind direction is consistent with the airflow direction, so that more airflow can pass through the radiator more smoothly, and the best heat dissipation effect has been achieved.
