[0025] During use, when air is input, it will flow through the interior of the filter box 14 after being input through the input pipe 4. Through the action of the filter plate 15, it can be filtered to filter out particles in the air and prevent the particles from remaining in the heat exchanger. This is beneficial to the stable circulation of air inside the heat exchanger and increases the stability of the use of the heat exchanger. At the same time, the filter plate 15 is installed on the mounting plate 16 by screws, so that the filter plate 15 can be removed for cleaning and the interior of the filter box 14 can be cleaned conveniently, which increases practicality.

[0026] Furthermore, a diverter pipe head 13 is fixedly installed on one side of the filter box 14, and connecting pipes 12 are symmetrically fixedly installed on both sides above the diverter pipe head 13, so as to facilitate the diversion of gas and facilitate heat exchange.

Then the air flows into the diversion pipe head 13, and flows into the two connecting pipes 12 respectively through diversion, and then flows into the corresponding cross pipes 7 respectively. The air is diverted and heat-exchanged in a double-channel manner, which is beneficial to improve the heat exchange efficiency. In addition, there are multiple cross pipes and elbows, which can increase the flow path and facilitate sufficient heat exchange. Then the air after heat exchange flows into the collecting pipe head 11 through the collecting pipe 10, and is then output through the output pipe 5.
