Description

A heat exchanger structure provided with an insulating layer

technical field

The utility model relates to the field of heat exchanger structures, in particular to a heat exchanger structure provided with a thermal insulation layer.

Background technique

In the past, water-refrigerant heat exchangers were generally not equipped with insulation, and heat loss inside the heat exchanger often occurred during use, resulting in reduced heat exchange efficiency and poor energy conservation. Moreover, when the unit operates in a low-temperature environment and encounters an emergency power failure, the water stored in the heat exchanger can easily cause the heat exchanger to freeze, which affects the safe and efficient operation of the unit.

In order to improve the heat exchange efficiency of heat exchangers, some manufacturers have tried to use foaming methods to insulate heat exchangers in recent years, but color steel plates must be used for waterproofing when foaming, because the installation process of color steel plates is complicated, resulting in low processing efficiency. In addition, there will be gaps in the installed color steel plate, resulting in poor waterproof performance.
