Electronic device and heat radiating module

Abstract

The present invention is a heat-scattered module used for being assembled onto the several locking holes on circuit boards and distributing heats of heat sources on circuit boards. The heat-scattered module includes a bearing frame, a fan and a covering part. The bearing frame is composed of bearing base and several first footings extending downward from the bearing base. Every first footing has a elastic locking part for locking in the locking holes, and the elastic locking part has a containing space. In addition, the fan is assembled on the bearing base, and the covering part covers the fan and is assembled on the bearing base. The covering part is composed of a casing and several second footings, in which the casing is used for covering the fan, and the second footings extend downward from the casing relative to the first footings. The side away from the casing of every second footings has a tenon inserted in the containing space.

Description

technical field [0001] The invention relates to a heat dissipation module, in particular to an electronic device and a heat dissipation module thereof. Background technique [0002] With continuous breakthroughs in semiconductor technology, the volume of integrated circuit (Integral Circuit, IC) components is getting smaller and smaller, and the operation speed is getting faster and faster. When the circuit is running, the temperature of the electronic components will rise, especially when the operation speed of the IC components is higher, the heating will become more serious. Among the IC components used in computer hardware, multiple IC components are often combined into a chip module to perform certain functions. Due to the high operating temperature, the IC components may malfunction or even be destroyed. Therefore, how to reduce the IC component Working temperature becomes a very important issue. [0003] For example, in a server (server), usually a plurality of memo...

Problems solved by technology

[0008] However, there are usually many power cables or boards such as RAID Cards inside the host computer, so the airflow generated by the system fan will be affected by the flow resistance of the power cables or boards, and cannot be convected. FB-DIMM, so that it may not be able to effectively dissipate heat from the FB-DIMM

[0009] In addition, due to the limited internal space of the host, it is not easy to have enough space inside the host to install an air guide cover to guide the air generated by the fan to the heating element.

On the other hand, even though there is enough space inside the mainframe to install the air guide cover, the airflow generated by the system fan is guided to the FB-DIMM through the air guide cover, and the airflow intensity has been greatly reduced, so that the electronic components cannot be effectively controlled. cooling
