Embodiment Construction

[0011] see figure 1 , the heat dissipation device is used for dissipating heat generated by an electronic component (not shown) mounted on a circuit board (not shown). The heat dissipation device includes a heat sink 10 , a fan 30 and a fixing frame 20 for fixing the fan 30 to the heat sink 10 .

[0012] The heat sink 10 is integrally made of metal material, and includes a heat conducting portion and a plurality of cooling fins extending from the heat conducting portion. The heat conduction portion includes a base portion 110, the bottom surface of which is in contact with the electronic components, and the middle part of the top surface of the base portion 110 obliquely extends outwards and upwards to extend two heat conduction wings 130, and the two heat conduction wings 130 form a “V” shape structure. The two wings 130 divide the fin into three regions: two first fin regions located between the base 110 and the wing 130 , and second fin regions located between the two win...

Abstract

A heat dissipation device, comprising a heat sink, a fan and a fixing frame for fixing the fan to the heat sink, the heat sink includes a base, heat conduction wings extending from the base, and a A plurality of first and second heat dissipation fins, two positioning grooves are provided on both sides of the radiator, the fixing frame includes a fan fixing panel and a positioning piece connected to the panel and positioned in the positioning groove, the above-mentioned panel includes a The lug fixed to the wing of the above-mentioned radiator and the protruding piece at the other end thereof, the ear is provided with a perforation, the wing of the above-mentioned radiator is provided with a screw hole corresponding to the perforation, and a screw passes through the perforation lock Fix it into the screw hole. The positioning piece of the fixing frame is directly positioned in the positioning groove of the radiator, so that the assembly of the fixing frame and the radiator is simple and convenient.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a heat dissipation device for dissipating heat from electronic components. Background technique [0002] As we all know, electronic components such as central processing units generate a lot of heat during operation. In order to prevent the temperature of the electronic component from rising due to the accumulation of heat and thus cause its operation to be unstable, the electronic component usually needs to be equipped with a heat dissipation device to assist in heat dissipation. [0003] Generally, the above-mentioned heat dissipation device includes a radiator, and the radiator has a bottom plate for contacting the electronic components to absorb heat and a plurality of cooling fins arranged on the bottom plate. In order to improve the heat dissipation capability of the heat sink, the heat dissipation device also includes a fan for providing strong convection airflow to the heat s...
