Description

Separated type cross flow slim type cooling module {SEPARATE TYPE CROSS FLOW SLIM TYPE COOLING MODULE}

The present invention relates to a cooling module. More specifically, it relates to a cooling module for cooling electronic equipment in which a heat generating load is generated inside.

For example, mobile communication electronic equipment such as communication repeaters are mainly installed outdoors such as on the roof or roadside, and are composed of a sealed enclosure that blocks external exposure because they are vulnerable to dust and moisture in the air. Electronic equipment is also composed of a sealed structure that prevents external exposure of internal parts.

Therefore, electronic equipment is inevitably vulnerable to internal heat generation due to its structure, and one of the effective methods for cooling such electronic equipment is to cool it using a cooling module.

In other words, elements that cause heat generation load are embedded inside the electronic equipment, so that a fan blower is attached to the case or a heat sink is attached to the element to solve internal heat generation. Since the blower alone cannot effectively prevent deterioration or performance degradation of the elements, an additional cooling module is used.

In order to avoid interference with internal parts, such a cooling module is operated, for example, attached to a door of an electronic equipment, and accordingly, a fan for cooling itself is generally manufactured in a slim shape.

However, the cooling module according to the prior art uses a slim turbo fan, and in the case of a slim turbo fan, there is a problem that static pressure and flow rate are limited and there is a problem that noise is large, so it is necessary to improve this.
