Air guide pipe of airflow exchange device

Abstract

An air guide pipe of an air flow exchange device is used for solving the problems that in the prior art, the sealing performance is poor, and noise is generated due to vibration, and the air guide pipe comprises: a hollow outer pipe body with a first opening and a second opening; a heat exchange unit arranged inside the hollow outer pipe body, and a first end face and a second end face are formedon the heat exchange unit; a hollow inner pipe body with a first air guide channel formed in the hollow inner pipe body; and a buffer piece attached between the hollow inner pipe body and the second end face of the heat exchange unit, and the buffer piece is communicated with the first air guide channel.

Description

technical field [0001] The invention relates to an air guide pipe, in particular to an air guide pipe of an air exchange device capable of enabling the external space and the internal space to achieve the function of circulation and ventilation. Background technique [0002] Please refer to figure 1 As shown, an existing air exchange device 9 is disclosed, and the air exchange device 9 can be installed on a spacer (for example: a wall, a ceiling of a building, or a casing of an electronic product, etc.). The air exchange device 9 includes an air duct 91 , a partition 92 , a heat exchange unit 93 and two fans 94 . The divider 92 is arranged inside the air guide pipe body 91, and the divider 92 can divide the inside of the air guide pipe body 91 into two guide spaces; the heat exchange unit 93 is combined with a joint port of the divider 92 921 ; the two fans 94 are respectively disposed on the two side surfaces of the partition 92 , so that the two fans 94 are respectively ...

AI Technical Summary

Problems solved by technology

[0003] In the above-mentioned existing air exchange device 9, for the convenience of assembly, the heat exchange unit 93 is usually loosely combined with the separator 92, and then fixed with a positioning component; however, this combination makes the heat exchange unit There is a gap between 93 and the separator 92, and this gap is also likely to cause the airflow to leak out, which affects the smoothness of the airflow exchange, and then leads to poor operating performance of the airflow exchange device 9 as a whole; in addition, in the airflow exchange During the operation of the device 9, the gap is likely to cause vibration or friction between the heat exchange unit 93 and the separator 92 to cause damage, or even noise, and in severe cases, it will also affect the performance and service life of the air exchange device 9
