Problems solved by technology

[0004] However, the above-mentioned heat dissipation device has the following disadvantages. Because the airflow of the fan is mainly concentrated on the heat dissipation fins, it is not easy to concentrate on the vapor chamber, so most of the vapor chambers rely on the heat dissipation fins to dissipate heat, causing the vapor chamber to easily dissipate heat. If it is not enough, it will accumulate heat, which will not effectively improve the heat dissipation efficiency of the heat sink

Abstract

The invention discloses a thin heat dissipating device comprising a uniform-temperature plate, a fan module and an annular fin group. The uniform-temperature plate has a condensing surface. The fan module and the uniform-temperature plate are fixedly connected with each other. The fan module includes a cover plate and a fan mounted under the cover plate, and the cover plate is provided with an air vent corresponding to the fan. The annular fin group is clamped between the cover plate and the condensing surface, and the annular fin group annularly surrounds the outer periphery of the fan. Thus, the fan is accommodated in a space formed by the cover plate, the condensing surface and the annular fin group and can blow air directly to the uniform-temperature plate and the annular fin group, and therefore, the heat dissipating efficiency of the thin heat dissipating device is improved.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a thinned heat dissipation device. Background technique [0002] As 3C products are widely used by the public, the computing speed and performance of electronic components (such as central processing units) in 3C products are continuously improved, resulting in higher and higher heat generated by electronic components. However, if the electronic components maintain high temperature It is easy to affect the computing efficiency, so the industry will use a heat sink to help the electronic components dissipate heat. [0003] Traditional cooling devices mainly include a vapor chamber, multiple heat dissipation fins, and a fan. One side of the vapor chamber is attached to electronic components, and the other side is connected to heat dissipation fins. The fan is then configured corresponding to the heat dissipation fins, so that the electronic components The heat is transferred from the v...
