摘要：

为提升氢燃料电池温度的一致性以及散热效能，以均温板作为研究对象，基于理论计算和试验验证搭建均温板计算模型。选取影响均温板传热性能的冷凝段长度、布置角度、冷却工质类型和充液率4个重要因素进行4因素3水平正交试验，并利用极差分析得到各因素各水平对均温板热阻和蒸发段工作面最大温差影响的权重关系。结果显示：在均温板热阻方面，冷却工质类型影响最为显著，冷却工质充液率次之，冷凝段长度对其影响最弱；在均温板蒸发段工作面最大温差方面，冷却工质充液率影响最为显著，冷凝段长度次之，冷却工质类型对其影响最弱。结合分析得到全组最佳组合方案，其热阻值为0.175 K/W，蒸发段最大温差为1.2 K，传热性能表现最佳。
