Description

一种电动汽车电池组双循环环境温度控制装置
技术领域:本发明涉及电动汽车电池组的环境温度控制装置,特别是一种半导体制冷制热的电动汽车电池组环境温度控制装置。
背景技术:现在市场上的电动汽车电池组没有安装环境温度控制装置,导致在环境温度过低时电池组的充放电工作性能很差,环境温度特别高时电池组必须停止工作,因此在使用环境温度要求方面的限制影响制约了电动汽车市场的发展。
发明目的:本发明的目的是提供这样一种电动汽车电池组的半导体制冷制热环境温度控制装置,它可以将电动汽车电池组的环境温度控制在规定范围内,保证电动汽车电池组的正常充放电工作性能,它具有结构简单,工作效率高的特点.
本发明的目的是通过下面的技术方案实现的:用导热性能良好的金属材料制作成合适的半导体制冷制热器后换热器和前换热器,选择高效的半导体制冷片,用半导体制冷片、后换热器和前换热器装配成半导体制冷制热器,半导体制冷制热器后换热器开有让液体冷媒通过的后换热器液体冷媒流入/流出口,半导体制冷制热器后换热器内部开有与后换热器液体冷媒流入/流出口相连通的S型弯曲的后换热器液体冷媒流动通路,半导体制冷制热器前换热器开有让液体冷媒通过的前换热器液体冷媒流入/流出口,半导体制冷制热器前换热器内部开有与前换热器液体冷媒流入/流出口相连通的S型弯曲的前换热器液体冷媒流动通路,用导热性能良好的材料制作成内部换热器,内部换热器开有让液体冷媒通过的内部换热器液体冷媒流入/流出口,内部换热器内部开有与内部换热器液体冷媒流入/流出口相连通的内部换热器液体冷媒流动通路,用导热性能良好的材料制作成复合换热器,复合换热器开有让液体冷媒通过的复合换热器液体冷媒流入/流出口,复合换热器内部开有与复合换热器液体冷媒流入/流出口相连通的复合换热器液体冷媒流动通路,制作专门的电子控制板,选择合适的内循环输液泵、外循环输液泵和换热风机,半导体制冷制热器与电子控制板相电气连接,内循环输液泵与电子控制板相电气连接,外循环输液泵与电子控制板相电气连接,换热风机与电子控制板相电气连接,内部换热器被安装在电动汽车电池组安装盒的内部,半导体制冷制热器与复合换热器被安装在电动汽车电池组安装盒的外部,其特征是:半导体制冷制热器后换热器、内部换热器和内循环输液泵用管路循环串联连通,半导体制冷制热器前换热器、复合换热器和外循环输液泵用管路循环串联连通,构成同一个温度控制装置内相互隔离的内、外双循环液体冷媒循环流动通路。
本发明的工作原理是这样的,这里以高温环境下电动汽车电池组的环境温度控制装置的制冷来举例说明,电动汽车电池组的环境温度控制装置通电后,半导体制冷制热器、内循环输液泵、外循环输液泵及换热风机开始工作,内部换热器不断地从电池组安装盒的内部吸取热量,通过与半导体制冷制热器后换热器相连通的液体冷媒的循环流动通路把热量传给半导体制冷制热器后换热器,再通过半导体制冷片的工作把热量传给半导体制冷制热器前换热器,再通过液体冷媒的循环流动把热量传给复合换热器,由于换热风机工作散热,复合换热器上的热量被不断散发到周围的空气中,电池组安装盒内部的热量被不断地吸走,温度降低,达到电动汽车电池组的环境温度控制在规定范围内的目的。
