Heat pipe type air heat recovery device

The utility model provides a heat pipe type air heat recovery device, which is divided into two air channels in complementary contact with each other, and is divided according to heating working conditions: one side is heating workshop air (hereinafter referred to as a heat source side), and the other side is heated workshop air (hereinafter referred to as a tail end side). In the air flowing direction of the heat source side, air firstly reaches the filter through the air port, reaches the external coil pipe after passing through the filter, then reaches the main heat pipe heat exchanger (theevaporative cooling device is located at the front end of the main heat pipe heat exchanger), and then is exhausted through the fan; in the air flowing direction of the tail end side, air firstly reaches the filter through the air port, reaches the external coil pipe after passing through the filter, then reaches the main heat pipe heat exchanger and then is exhausted through the fan. After air on the two sides is exchanged through the heat exchange device, the phase change material in the heat pipe absorbs and releases heat energy through liquid-gas phase state changes so as to achieve the purpose of heat energy exchange.
