Comparison of Heat Transfer Performance of Simulated Radiator and Simulation of Resistance Performance of Radiator

Dual-drain type radiator simulation data, wave length can be seen from the simulation data, the first discharge water flow is basically the same, but the first heat pipe discharge is significantly smaller than the first row, only the first row. According to the simulation results, the temperature of the air cooled by the cooling air and the first drain pipe rises, and the air inlet temperature for heat exchange with the first drain pipe rises, so that the average temperature difference between water and air in the first drain pipe decreases. According to the knowledge of heat transfer, the heat dissipation coefficient of the radiator is related to the average temperature difference between water and air. This is the reason that the heat dissipation of the first drain pipe is significantly smaller than that of the first row. Results Comparison and Conclusions The analysis table and table compare the heat transfer performance and resistance performance of a single drain pipe and a double drain pipe radiator.

Table Analog heatsink heat transfer performance comparison table Simulation of heatsink resistance performance comparison From the table shows that, although the dual drain pipe radiator cooling area is double the single drain pipe radiator, but under the same conditions, double drainage The heat dissipation of the tube type is higher than that of the single water discharge tube type, but the wind resistance is increased by nearly double. At the same time, the material used to manufacture the dual-drain pipe radiators is also a single-drain pipe, so the quality and manufacturing cost of the radiators will increase accordingly. Taking into account the heat transfer performance, resistance performance, economical efficiency, and reliability of the radiator, it is not the most effective method to increase the radiator heat dissipation by increasing the number of water pipes. In the actual design of automotive radiators, improving the heat transfer coefficient of the tube-belt heat sink should be considered from the aspects of optimizing the structure design of the radiator and improving the manufacturing process. By conducting a heat transfer wind tunnel test on a commercial automotive tubular heat sink and conducting numerical simulations, according to a comparative analysis of the simulation results, under the same working conditions, the heat dissipation of the dual drainage pipe type is only increased compared with the single drainage pipe type. However, wind resistance has increased by nearly double, and manufacturing materials have also increased by nearly double. Therefore, considering the heat transfer performance, resistance performance, economic efficiency, and reliability of the radiator, it is not the most effective method to increase the heat dissipation of the radiator by increasing the number of water pipes.
