Air duct for air exchange unit

Abstract

An air duct for an air exchange device is used to solve the problems of poor sealing and easy vibration resulting in noise in the prior art, which includes: a hollow outer tube body with a first opening and a second opening ; a heat exchange unit, arranged inside the hollow outer tube body, the heat exchange unit is formed with a first end surface and a second end surface; a hollow inner tube body, a first air guiding channel is formed inside the hollow inner tube body and a buffer piece, the buffer piece is attached between the hollow inner tube body and the second end surface of the heat exchange unit, and the buffer piece communicates with the first air guiding 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
