Description

Fixing structure of radiator

Technical field

The utility model relates to a kind of radiator structure, particularly a kind of location structure in order to fixed heat sink.

Background technology

Growing with each passing day down for lightening demand at present, electronic installation constantly moves towards miniaturization, also directly drive height requirement for heat radiation, therefore in order to improve the radiating efficiency of electronic installation, directly radiating subassembly is assembled in and has become the most normal a kind of technological means that is used at present on the heat generating component, the radiator structure that particularly will have a plurality of high cooling efficiency fin, directly contact in conjunction with the quick conductive medium with heat generating component, to improve heat dissipation for heat generating component, in view of this, how heat generating component and radiator structure with fin are formed firm connection, become current a kind of considerable research topic.

And in the prior art in the past, the most common mode is to utilize the pedestal in the radiator structure directly to be installed on the heat generating component, and the heat-conducting glue of tool thermal conductive property is added in utilization on the composition surface of pedestal and heat generating component, described pedestal and heat generating component can firmly be fitted and heat conduction smoothly, yet, electronic installation with radiator structure unavoidably can be because carrying or other former thereby generation impact events, make and take adhesive agent to produce deviation or displacement with engaging of heat generating component, described radiating efficiency is had a greatly reduced quality as the radiator structure pedestal that engages interface.

Therefore the prior art after just takes the fastener form to fix the position of radiator structure pedestal and heat generating component, structure as shown in Figure 1, described radiator structure 10 has a pedestal 101 to be supported in order to directly to paste with heat generating component, and above described pedestal 101, be provided with a plurality of fin 102, in addition, offer a chute 103 that runs through pedestal 101 both sides in pedestal 101 bottoms, and a fixed lever 104 is set in chute 103, be respectively equipped with

screw

104a and 104b on described fixed lever 104 two ends simultaneously, in order to sheathed locked assembly 11, fixation by locked assembly 11 forms amount of pressure, through pressing of the fixed lever 104 that wears pedestal 101, described radiator structure 10 is formed a fixed connection with heat generating component.

Yet in the above-mentioned structure of saying, see through the below that fixed lever 104 is located in pedestal 101, see through fixed lever 104 two

ends screw

104a and 104b again, the fixation that is connected to form that cooperates locked assembly 11, see it with another visual angle, as shown in Figure 2, described fixed lever 104 the position of centre of gravity that the position can't effectively press described radiator structure 10 is set, and formation case of bending, cause 104 dual-sides of described fixed lever to press with a way of contact with pedestal 101, therefore described fixed lever 104 still can be subjected to the external force influence easily and cause slip, make described radiator structure 10 and heat generating component relative position produce the displacement situation, lower the thermolysis of radiator structure 10 greatly, also cut down the described practicality of utilizing fastener positioning combination mode, cause the not most desirable part of described mode for heat generating component.

Summary of the invention
