While the rear heat collecting plate is not usually designed with a through hole, in an alternative embodiment, the size (i.e. the bearing area) of the rear heat collecting plate gradually increases from the side close to the inlet to the side close to the outlet.
The structure design can enhance the effect of the heat collection balance, simultaneously improve the balance of heat absorption of each heat collection device as much as possible, the heat collection plate through hole near the inlet is large, the passing speed of steam or hot water entering the heat exchange cavity from the inlet is properly increased, and the waste heat of the steam or the hot water entering the heat exchange cavity is less and less, so the heat collection effect is improved by the design form of reducing the diameter of the through hole of the heat collection plate at the rear end, and the balance of heat collection of each heat collection device is improved as much as possible. In addition, the structural arrangement can be further optimized, and the distance between two adjacent heat collecting devices is gradually reduced from one side close to the inlet to one side close to the outlet.
The heat conducting assembly comprises a plurality of groups of heat collecting pipes which are arranged side by side and have U-shaped structures. In order to improve the heat conduction capability between the heat collection plate and the heat conduction assembly, the cross section of the heat collection tube is preferably designed to be rectangular.

In an alternative embodiment, as shown in fig. 4, the heat collection chamber is filled with circulating water, and a stirring device 14 is arranged in the heat collection chamber; the shell is provided with a water outlet and a water return port corresponding to the heat collection chamber. The stirring device can be a motor driving stirring paddle, so long as the flow of circulating water in the heat collection chamber can be disturbed, and the temperature in each part of the heat collection chamber is balanced. The front heat collecting plate and the rear heat collecting plate are both made of aluminum plates or copper plates. The recycled heat energy is utilized to heat circulating water, and the circulating water can be directly applied to heating and warming of indoor environment or equipment structure.
