Description

Installation fixing structure of radiator on circuit board

Technical Field

Background

Generally, in a product with a complex circuit and large power consumption, a problem that the service life of the product and the user experience are affected, that is, the temperature of the product is high, often occurs. Not only does this affect the use of electronic components resulting in a reduction in product life cycle, but also poor user feedback results in reduced sales. At this moment, the inside of the product can use the radiator to reduce the temperature of the electronic element at a higher speed, thereby ensuring the good use of the product.

Generally, a radiator with screw holes is used for locking a heating area to dissipate heat or the radiator is directly adhered to a heating component by silica gel. The radiator has higher cost and needs to be fixed by screws, so that the fixing cost is increased, and the labor cost is increased. The latter is easy to operate, has lower overall cost, but has low reliability, is difficult to resist vibration and fall, and directly leads to falling off.

In view of the above, the present invention is particularly proposed.

Examples

Referring to fig. 1-5, a mounting and fixing structure of a heat sink 30 on a circuit board 10 according to the present embodiment includes: circuit board 10, heating element 40, heating panel and fixed bolster 20. The circuit board 10 is a substrate, and the heating element 40 is mounted on the circuit board 10 by soldering. The heat sink 30 is fixed directly above the heat generating component 40 by the fixing bracket 20.

The fixing bracket 20 is designed as an integral body, and the upper side of the fixing bracket is provided with a direction clamping block, wherein the direction clamping block further comprises a clamping plate 201 for limiting the horizontal direction and a clamping hook 202 for limiting the vertical direction. The clamping plates 201 are tightly attached to two sides of the heat sink 30, and the hooks 202 are inserted between the gaps of the heat sink 30. The clamping plate 201 is actually attached to the heat sink 30, so that the positive and negative directions of the X axis and the negative and positive directions of the Y axis of the heat sink 30 on the circuit board 10 can be limited, the shape of the hook 202 is L-shaped and penetrates through the gap of the heat sink 30, wherein the short edge hooks the heat sink 30 to limit the positive direction of the Z axis of the heat sink 30 on the circuit board 10, and the negative direction of the Z axis is fixed because the heat sink 30 is directly installed and fixed on the circuit board 10, so that it can be seen that the installation fixing plate can limit the displacement of the heat sink 30 on the circuit board 10, and the firmness is strong.
