The product is composed of many single heat pipe. The size of the quantity of the heat pipe depends on how much heat transfer. In order to improve the heat transfer coefficient of gas, often take in the tube and fin method, so that the required number of heat pipes is greatly reduced. The heat pipe heat exchanger is mainly composed of a casing, a heat pipe element and cold, heat fluid inlet and interface. Housing is a steel structure, one side is a hot fluid channel, on the other side of the cold fluid channel, separated by the tube plate. Two sides of the lower hole plate and the cover plate of the shell, and the equipment are equipped with thermal insulation layer. Last, cover is detachable structure, convenient maintenance and replacement of the heat pipe.
