Problems solved by technology
[0005] In order to solve the above problem, the longitudinal cross-sectional area of the exhaust air inlet passage is much smaller than the longitudinal cross-sectional area of the fresh air inlet passage, so that compared with the fresh air inlet passage, the exhaust air inlet passage is not smooth, the pressure loss is large, and the wind speed is lower than that of the fresh air inlet passage. Compared with the technical problem of the large difference in the wind speed of the channel, the invention provides a heat exchange device to improve the heat exchange efficiency while realizing the miniaturization of the structure

The invention provides a heat exchange device. The heat exchange device comprises a frame body, an air supply air inlet, an air exhaust air inlet, an air inlet path, an air exhaust path, a heat exchange unit and an airflow partition plate. The included angle formed by the air inlet face, located in the exhaust air path, of the heat exchange unit and the plane where the top wall of the frame body is located and the included angle formed by the air inlet face, located in the air inlet air path, of the heat exchange unit and the plane where the bottom wall is located are both larger than 0 degree and smaller than 90 degrees. The airflow partition plates comprise the first airflow partition plate, the second airflow partition plate and the third airflow partition plate, and the length of the first airflow partition plate in the direction from the heat exchange unit to the third side wall is gradually shortened from the exhaust air inlet side to the air supply air inlet side. And gaps for air flow of the air inlet path are formed between the first airflow partition plate and the third airflow partition plate and the third side wall. Therefore, the heat exchange efficiency can be improved while the structural miniaturization is realized.
Description
technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchange device. Background technique [0002] The existing heat exchange device with heat exchange function can make the fresh air inhaled from the outside and the old air discharged from the room exchange energy through the heat exchange element or other heat exchange components, thereby adjusting the temperature of the fresh air and providing a suitable temperature for the room. new wind. This kind of heat exchange device has the characteristics of lower energy consumption, so it is more and more accepted by consumers. [0003] Currently, there is a heat exchange device disclosed in the patent document CN206572700U on the market. Such as figure 1 As shown, in order to realize the miniaturization of the heat exchange device, its fresh air inlet passage 11 and exhaust air inlet passage 12 are arranged parallel to each other on one side of the box body 1, and the ...
