The louver 22 of the windward side of the wind catcher frame 21 is forced to turn inwards around the rotation center of the louver to be opened, so that the inside and the outside of the wind catcher frame 21 are communicated, and air enters the heat exchange pipeline 1 through the air port 211; at the same time, the lee surface and the side surface facing away from the windward side of the wind catcher frame 21 are subjected to negative pressure, the louver 22 is closely attached to the inner wall of the wind catcher frame 21, the louver 22 is closed, and air cannot flow out. The windward side is influenced by the wind direction, and the opened louver 22 is changed along with the windward side, but the opening at the windward side can be always ensured, and the air only flows in from the direction of the louver 22 on the windward side of the wind catcher frame 21 and does not flow out. Fig. 3 is a schematic diagram of the windward side and the leeward side of the blade in this embodiment, where +indicates the windward side and-indicates the leeward side.

The air outlet pipe 23 is fixedly arranged at the center of the air catcher frame 21, the upper end of the air outlet pipe 23 extends to the outside of the air catcher frame 21, the lower end of the air outlet pipe is communicated with the heat exchange pipeline 1, and the opening at the upper end of the air outlet pipe 23 is stably subjected to negative pressure to suck air out of a room.

With reference to fig. 4 and 5, the heat exchange pipe 1 is internally provided with the heat pipe 3, the wind catcher is combined with the heat pipe 3, and cold and hot air is exchanged at the heat pipe 3, so that the heat exchange efficiency can be ensured while maintaining sufficient ventilation

The heat exchange pipeline 1 comprises an inner pipe 11 and an outer pipe 12 which are coaxially arranged, a through hole is formed in the center of the bottom wall of the wind catcher frame 21, the through hole is communicated with the air inlet channel 5 and the inside of the wind catcher frame 21, and the lower end of the air outlet pipe 23 penetrates through the through hole and is communicated with the inner pipe 11. An air inlet channel 5 is formed between the inner tube 11 and the outer tube 12, the air inlet channel 5 is used for introducing outdoor fresh air, and the inner tube 11 is used for discharging indoor circulated air.

The inner tube 11 is composed of two oppositely arranged arc plates 111 and two oppositely arranged straight plates 112, and the arc plates 111 and the straight plates 112 are connected end to form a closed area.

The air inlet channel 5 is internally provided with two opposite blocking blocks 6, the blocking blocks 6 are provided with cambered surfaces and straight surfaces, wherein the cambered surfaces are attached to and fixedly connected with the inner wall of the outer tube 12, the straight surfaces are attached to and fixedly connected with the straight plates 112 of the inner tube 11, the air inlet channel 5 is internally divided into a heat pipe 3 area and a non-heat pipe 3 area under the action of the two blocking blocks 6, the heat release section of the heat pipe 3 is positioned in the heat pipe 3 area of the air inlet channel 5, and the heat absorption section of the heat pipe 3 is positioned in the inner tube 11.

It should be noted that, the heat recovery efficiency of the heat pipes 3 depends on the number and arrangement density of the heat pipes 3, in this application, for example, 80 heat pipes 3 can recover more than 30% of the temperature difference, that is, 40% of the temperature difference of the cold and hot air can be recovered into the fresh air for heating the cold air in winter and cooling the hot air in summer. Heat exchange between 20 c indoor air and 0 c outdoor air can provide fresh air exceeding 6 c into the room. Increasing the number of heat pipes 3 increases the heat recovery efficiency to 90%, but decreases the air flow rate. When the heat pipe is applied under the condition of large indoor and outdoor temperature difference, more energy sources are saved, and the number of the heat pipes 3 can be increased as appropriate.

The implementation principle of the application is as follows: when the heat pipe 3 is used for heat recovery and energy saving, outdoor air flows into a room through the heat pipe 3 by opening the louver 22 facing the windward side of the wind catcher through the windward side of the wind catcher frame 21.

Taking winter as an example, outdoor cold air flows in through the air inlet 211 and then enters the outer air inlet channel 5, and indoor hot air enters the inner pipe 11 through the indoor air outlet 211. The cold air and the hot air flow in opposite directions in adjacent air channels, and the heat exchange efficiency is high. The heat pipe 3 has strong heat exchange capability and small pressure loss to fluid, and can ensure heat exchange efficiency while maintaining sufficient ventilation. The fresh air supply is ensured, and meanwhile, the heating energy requirement is reduced. In summer, on the contrary, indoor cold air exchanges with outdoor hot air when being discharged, so that the refrigeration energy requirement is reduced.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
