Description

Technical Field

[0001] The utility model relates to the field of cooling equipment, in particular to a cooling device for a computer mainboard. Background Art

[0002] The computer case motherboard, also called the main board, system board or motherboard; it is divided into commercial motherboard and industrial motherboard. It is installed in the case and is one of the most basic and important parts of the microcomputer. When the computer motherboard works for a long time inside the case, it will generate a high temperature. The existing heat dissipation device usually uses a fan for heat dissipation, but the existing cooling fan will start with the host startup. When the case temperature is low, the fan's work is redundant, and the existing fans are usually installed in a single group. When in use, they can only dissipate heat and cool down the part of the motherboard, and the cooling effect is relatively general.

[0003] At present, a Chinese utility model with the announcement number CN211742038U discloses a computer motherboard cooling device, which relates to the field of computer technology and includes a main body, wherein the front outer surface of the main body is provided with a controller and a power interface, and the power interface is located on one side of the controller. The computer motherboard cooling device described in the utility model can monitor the temperature inside the computer case when in use through the setting of a temperature monitor, and can control the cooling fan to start according to the temperature change to dissipate heat for the computer motherboard when in use, which saves power resources when in use, and can be beneficial to cooling the computer motherboard when in use through the setting of the cooling fan, and can control the individual cooling fans to start according to the actual situation through the grading module when in use, and its four groups of cooling fans can expand the heat dissipation area of ​​the computer motherboard when in use, and the effect of use is better than that of the traditional method.

[0004] To sum up, although the device can achieve the effect of expanding the heat dissipation area of ​​the computer motherboard, there are still certain problems when using it. For example, the device uses four groups of cooling fans to dissipate heat for the computer motherboard, and each group of cooling fans uses a separate power transmission, which results in the four groups of power equipment working at the same time when in use. As a result, the power consumed during operation is also relatively high, and the purpose of energy saving cannot be achieved. At the same time, the bracket part of the cooling device is structurally fixed after installation, so that the position of the threaded holes on the bracket is fixed. When encountering computer motherboards of different sizes, if the size of the computer motherboard is larger than the cooling device, it will hinder the installation of the bracket of the cooling device and prevent it from being fixed normally.
