新型带冷却棒式车载冰箱的传热特性模拟研究
Numerical Simulation on Heat Transfer Characteristics of a Novel Vehicle Refrigerator with Cooling Rod
摘要
Abstract
The cooling rate and temperature uniformity of the vehicle refrigerator are important indicators for evaluating the cooling effect of the vehicle refrigerator.In this paper,a new type of vehicle refrigerator with cooling rods is proposed.Using ANSYS-Fluent to simulate the effects of four different diameter and height ratios of column cooling rods on the cooling rate and temperature uniformity of the fluid in the box.The air flow characteristics of the optimal air flow arrangement in the box were compared and analyzed.The results show that the cooling rod with a diameter of 26 mm and a height of 240 mm has the greatest heat transfer,and the temperature inside the box can be reduced from 298.15 K to 277.15 K with a cooling rate of 0.04 K/s by about 350 s.Compared with the other three kinds of cooling rod structures,the cooling rate of the box is about 150 s faster on average.And the temperature uniformity and air flow uniformity in the box are better.关键词
