Problems solved by technology

[0003] The heat sink is fixed on the main board by a fixed module so as to dissipate heat to the central processing unit; however, the fixing methods of the existing radiator and the fixed module all use screws to fix the fixed module on the main board first, Then use the auxiliary fastener to fix the radiator on the fixed module, which greatly reduces the production efficiency and assembly efficiency

Embodiment Construction

[0014] see figure 1 and figure 2 , the heat dissipation device of the present invention is used to dissipate heat to a heat-generating electronic component on the circuit board 30 such as a central processing unit 32, and it includes a heat sink 20 and a fixing module for fixing the heat sink 20 on the circuit board 30 10. The fixing module 10 can be pre-assembled with the heat sink 20 before being mounted on the circuit board 30 .

[0015] Also see image 3 The radiator 20 is an extruded aluminum radiator, including a base 22 and a plurality of cooling fins 24 extending vertically upward from the base 22 . Front and rear opposite ends of the base 22 are obliquely cut to form two slopes 220 , 221 , so as to facilitate the insertion of the radiator 20 into the fixed module 10 . In this embodiment, the slope 220 and the slope 221 are asymmetrical, wherein the angle between the slope 220 and the bottom plane of the base 22 is larger than the angle between the slope 221 and t...

Abstract

A heat radiating device comprises a fixed module and a heat radiator mounted on the fixed module, wherein, the fixed module includes a pair of support arms arranged separating from each other and a connection plate connecting opposite ends of the two support arms, a pair of oppositely-arranged positioning lugs extend upwards from connection positions of the support arms and the connection plate; the heat radiator includes a base seat arranged on the support arms and a plurality of heat radiating fins extending upwards from the base seat, a fastening portion fastened with the heat radiator base seat is formed on each support arm. In the invention, the fastening portion fastened with the heat radiator is mounted on the fixed module, pre-assembling of the fixed module and the heat radiator can be realized before the fixed module is mounted on a circuit board, the assembling is convenient and quick thereby improving assembling efficiency.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a heat dissipation device applied to electronic components. Background technique [0002] With the rapid development of the electronic industry, the computing speed of the electronic components in the computer has been greatly increased, and the heat generated by it has also increased sharply. How to dissipate the heat of the electronic components to ensure their normal operation has always been a must for the industry. The problem. As we all know, the central processing unit installed on the motherboard is the core of the computer system. When the computer is running, the central processing unit generates heat. Excessive heat can prevent the CPU from functioning properly. In order to effectively dissipate the heat generated by the central processing unit during operation, a radiator is usually installed on it so that the heat generated by it can be dissipated. [0003] The heat si...
