摘要:

为了提升聚合物电解质膜燃料电堆散热性能,提出了将均温板作为散热结构置于聚合物电解质膜电堆内,探究了均温板蒸发段换热系数以及布置角度对目标电堆散热性能影响。研究结果表明,目标电堆平均温度和温度均匀性指数随均温板冷凝段对流传热系数增大而降低;重力布置角度和水平布置角度下电堆温度平均温度和温度均匀性要优于反重力布置角度;随着负载的增大,均温板可使目标电堆温度均匀性指标低于1.1,可使受热物体具有较好温度分布。

关键词: 燃料电池, 均温板, 温度分布, 布置角度, 对流换热系数

Abstract:

In order to improve heat dissipation performance of polymer electrolyte membrane fuel cell reactor, a temperature equalization plate was proposed as a heat dissipation structure in polymer electrolyte membrane battery reactor, and the influence of heat transfer coefficient of evaporation section of temperature equalization plate and arrangement Angle on the heat dissipation performance of target reactor was investigated. The results show that the average temperature of the target reactor and the temperature uniformity index decrease with the increase of the convective heat transfer coefficient in the condensation section of the temperature homogenizer. The average temperature and temperature uniformity of the reactor temperature are better than that of the antigravity arrangement Angle under gravity arrangement Angle and horizontal arrangement Angle. With the increase of the load, the temperature uniformity index of the target reactor can be lower than 1.1, and the heated object can have a better temperature distribution.

Key words: Fuel Cell, Uniform Temperature Plate, Temperature Distribution, Layout Angle, Convective Heat Transfer Coefficient
