Oscillating flow heat pipe automotive radiator has huge advantages

The wind resistance of the two radiators increases with the increase of wind speed, and under the same wind speed, the wind resistance of the oscillating flow heat pipe car radiator is smaller than that of the tube-strip copper car radiator. When the wind speed is small, the wind resistance difference between the two radiators is smaller, but as the wind speed increases, the difference becomes larger and the advantages of the oscillating flow heat pipe automotive radiator become more obvious. When the wind speed is 8.2m/s, the wind resistance of the oscillating flow heat pipe car radiator is 272.5Pa, which is 30.3Pa lower than the wind resistance of the tube-belt copper car radiator. Four types of water flow rates ranging from 0.5m/h are selected. The water resistance is measured under the working conditions, and the experimental results are shown in Figure 9. It can be seen from the Journal of Refrigeration that the water resistance of the two radiators increases with the increase of the water flow, and under the same water flow, the water resistance of the oscillating flow heat pipe automobile radiator is much smaller than that of the tube strip. Style copper car radiator. Under the four working conditions, the water resistance of the oscillating flow heat pipe car radiator is 940Pa lower than that of the tube-belt copper car radiator.

Thermal balance error The heat dissipation of water and the heat absorption of air are theoretically equal, but due to the limitation of experimental conditions and instrument accuracy, there is an error in the heat dissipation and heat absorption calculated by measurement. This part of the error is analyzed to determine the reliability of the experimental results. Calculation method of thermal balance error. Through experiments on the oscillating flow heat pipe car radiator and the tube-strip copper car radiator, the heat dissipation performance and resistance characteristics of the two radiators at different wind speeds and water flows are studied. The results show that the heat dissipation performance of the oscillating flow heat pipe car radiator under the same working conditions is better than that of the tube-strip copper car radiator, and its wind resistance and water resistance are smaller than that of the tube-strip copper car radiator. After error analysis, the experimental results are accurate and reliable. Therefore, compared with the tube-belt copper car radiator, the oscillating flow heat pipe car radiator has huge advantages and is the best choice for the development of a new type of car radiator.
