对家用空调器，电控器散热通常使用铝挤型材散热器，对高性能变频热泵空调，常规的铝型材散热器已不能满足散热需求，市场上已有厂商采用液冷散热，即从压缩机冷媒管路上引出旁路，连接至电控器的液冷板冷却管路，利用冷媒流动带走电控器功率器件的热量，达到电控器散热降温的目的。但这种散热方式需要设置冷媒进出管道，使的整个空调冷媒管路系统复杂，同时也增加了冷媒量及压缩机载荷，且因为增加冷媒支路需要接头连接和新的管道,不仅增加了成本,还增加了冷媒系统的泄漏点，降低了系统的可靠性。
热超导散热板是在一金属板上设置有网格状的相互连通的封闭管道，在封闭的管道内充装有工作介质，构成具有导热速率快,均温性好,传热功率大的一种新型板式传热器件。
