Description

Fixed support column and radiator with same

Technical Field

The present utility model relates to the field of communications devices, and in particular, to a fixed support column and a heat sink having the same.

Background

Because of the heat dissipation problem of the chip, many chip manufacturers currently adopt the lid package to design the chip into a bare chip form so as to reduce the thermal resistance of the chip.

As the power consumption and the size of the chip become larger, the size, weight and fastening force of the corresponding heat sink become larger. However, the pressure value that the large-size bare chip can bear is very low under the condition that the heat sink is not protected, and the large-size bare chip is easily damaged in the processes of radiator installation, product vibration and transportation.

The traditional screw or pin radiator only adopts a spring structure fastening mode, and the radiator cannot be effectively fastened due to the change of spring force, so that a larger inclined angle can be formed between the radiator and a large-size bare chip in the processes of assembly, product vibration and transportation at a certain moment, the contact area of the radiator and the large-size bare chip is reduced, the pressure intensity of a local area is overlarge, and the large-size bare chip is easily damaged.

Currently, in order to solve the problem of large floating sloshing, a part of the radiator is designed with a rigid support column on a single board (or on the radiator) to reduce the inclination of the radiator. However, such rigid designs are often designed with a large gap between the board (or heat sink) and the support posts due to the accumulation of various tolerances, and do not completely prevent the heat sink from tilting. If the gap between the radiator and the positioning column reserved in design is smaller or the interference design is adopted, the fastening force is possibly insufficient, and the heat dissipation of the chip is further affected.
