液体冷却一直被认为最有效的冷却方法。在现代塑料加工，工业中，水冷加热及油冷加热作为标准设备，但在使用过程中，由于水质未经软化净化处理，冷却管结垢过早失效，及油冷却的油路堵塞、漏油等，影响设备正常使用和停机维修等缺点。风冷加热器就避免了这些缺点，风冷加热器由几个连接而成的带状加热器，组成一个加热区，单独固定冷却，最高温度500℃是国内外目前最先进的冷却装置。
Liquid cooling was always considered as the most effective cooling way. In mwdern plastics processing and others industries, water-cooling and oil-cooling devices are the standard equipments. During the process, these equipments were always power off to repair for the impure water or oil. Air cooling and heating device was made by many strip heaters to make up heated area. It was solely fixed up and it is the most advanced cooling device in the world. Its maximum cooling temperature is 500℃.
