Background

Heat exchangers are devices used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements, and are an industrial application of convective and conductive heat transfer. Heat exchangers can be classified in different ways. The operation process can be divided into three categories of dividing wall type, mixed type and heat accumulating type (or called regenerative type); the degree of compactness of the surface thereof can be classified into two types, compact and non-compact.

The heat exchanger comprises two structural modes according to different placing positions, wherein one mode is that the heat exchanger is arranged outside the inner container of the water tank and is not in direct contact with water, and the heat exchanger transfers heat to stored water in the water tank through the inner container of the water tank, namely is externally arranged; the other is placed in a water tank and immersed in water, and the heat exchanger is directly contacted with the water, namely the heat exchanger is built-in.
