一站式服务

套管式热交换器外管材料一般采用紫铜，厚度1mm以上，为增加热交换效率，高档的套管式热交换器的外管表面做成凹凸状，以期冷热水在套管表面形成涡流，但水垢一般首先在凹面富集，因此使用3-6月后也就无所谓涡流了。套管式热交换器成本较板式高、体积也增大，但热交换效率较低；因其外套管较厚，相较板式交换器不易锈蚀穿孔（在一些水源较差的地方仍时有发生）而被很多热泵厂家采用；但因其热交换效率低，必须提高其表面温度，因此主机工作时需较大的压缩比，和采用板式热交换器比，同样的制热量其主机功率要大一些，再加上套管热交换器体积大、成本高，因此不仅整机成本提高，能耗也增大；同时，它只是延缓了故障的发生时间，一般一至两年后，同样要采取除垢工作，否则仍会出现种种故障。
