Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange equipment, in particular to a heat exchange device. Background Art

[0002] With the development of big data technology and artificial intelligence technology, the number of switches and servers in use has increased rapidly, and the demand for heat dissipation devices has also increased significantly.

[0003] Most existing heat dissipation devices adopt a back heat dissipation method, and the heat dissipation path is usually heat source → heat sink → back exhaust. Although this method can directly discharge heat out of the chassis, it has certain limitations. For example, in some servers, due to space layout limitations, the heat dissipation device needs to be set at the bottom, so the height and width of the heat exchange device are limited. The traditional straight-line radiator has a small effective heat dissipation area in the bottom space, resulting in insufficient heat dissipation capacity and difficulty in meeting the heat dissipation requirements of high-power equipment. In addition, in order not to affect the air inlet area of ​​the straight-line radiator, the circuit board (i.e., the control unit) of the heat dissipation device is mostly installed on the side wall of the shell (such as the patent document with publication number CN215991728U), which is not conducive to the rapid heat dissipation of the circuit board. In addition, the filter in the traditional heat dissipation device is installed horizontally and is connected in series with the pipe through a flange, which is not conducive to the rapid replacement of the filter element.
