Abstract

The utility model discloses a radiator comprising a substrate and a plurality of heat radiation fins vertically arranged thereon. The heat radiation fins are distributed in a rectangular manner and are divided into three heat radiation groups, and a space is formed between each two adjacent heat radiation groups. The radiator is provided with a clamping member which penetrates the substrate, and a spring is sleeved on the clamping member. Through the above way, the radiator, without heat-conducting glue, can be directly fixed on a mainboard and can be placed at any angle without falling.

Description

A kind of radiator

Technical field

The utility model relates to the heat dissipation equipment field, particularly relates to a kind of radiator for electronic product.

Background technology

Along with the continuous progress of integrated circuit technique and improving constantly of commercial Application demand, electronics and information industry vigorously develops rapidly, computer application is popularized, and the speed of its update is accelerated increasingly, therefore, the running frequency of the core parts-central processing unit in computer is more and more higher, the high-frequency high-speed processor is constantly released, but the processor running frequency is higher, the heat produced in its unit interval is more, accumulation of heat will cause that temperature raises, thereby cause its runnability to comprise stability decreases, therefore, must in time the dissipation of heat of its generation be gone out, at present, the essential problem solved when heat radiation has become every generation high speed processor release.For the heat can be rapidly integrated circuit (IC) chip produced when the high-speed cruising, drive away, industry is settled a radiator of being made by the material with good heat conductive performance more than the integrated circuit (IC) chip upper surface.In various mainboard now, nearly all can use radiator is the electronic component on it, as central processing unit and South Bridge chip etc. is dispelled the heat.Usually, radiator comprises radiating part and installation portion.Wherein, radiating part mainly comprises radiating fin, for heat radiation; Installation portion comprises fastener, for radiating part is fixed in to mainboard.And fastener generally includes the retaining elements such as clasp, depression bar and screw, because installation portion has more retaining element, the assembling of radiator just comparatively bothers, and its production and assembly cost are also higher.It is the formation that combines with matrix radiating fin on aluminium base with aluminium base that radiator is certainly also arranged, aluminium base is fixed on mainboard by heat-conducting glue, do not need installation portion, but this radiator is in installation process, due to the position difference of different mainboards, sometimes need in installation process to do and keep away the position processing, utilize the fixing words of heat-conducting glue, easy detachable not, and be not easy to do and keep away position and process.

The utility model content

For above-mentioned deficiency of the prior art, the utility model main purpose is to provide a kind of radiator, without using heat-conducting glue, can directly be fixed on mainboard, and arbitrarily angledly all can place, and radiator can not come off.

For achieving the above object, the technical solution adopted in the utility model is: a kind of radiator, comprise a substrate and stand and be located at the some radiating fins on described substrate, described some radiating fins become rectangular to arrange, described some radiating fins form three groups of radiating fin groups, in described three groups of radiating fin groups, between two adjacent groups, are provided with interval; Described radiator is provided with fastener, and described fastener runs through described substrate, on described fastener, is arranged with spring.

Preferably, an end of described fastener is provided with dop, and described dop stretches out the back side of described substrate, the other end of described fastener is provided with the card cap, be arranged with spring between described card cap and described substrate, described fastener, under spring action, can be regulated the length that dop stretches out described substrate.In the utility model, utilize the fastener with spring that radiator is fixed on pcb board, and, due to the elastic reaction of spring, radiator is applicable to the pcb board of different-thickness.Utilize fastener to fix, and conveniently replaced, and can be fixed on the arbitrary position on pcb board, without using heat-conducting glue, cost-saving.

Preferably, described fastener is provided with two, and described two fasteners lay respectively at three groups of intervals between the radiating fin group.

Preferably, in described three groups of radiating fin groups, the radiating fin in every group is counted difference.Radiating fin number in three groups of radiating fin groups described in the utility model can be adjusted according to model and the kind of radiator, to meet the heat radiation needs of different product.

Preferably, described substrate is rectangular.

Preferably, described radiating fin all is cuboid.Radiating fin described in the utility model also can need or product needed according to heat radiation, is designed to other shapes.

Preferably, described fastener is made by nylon material.

Preferably, described substrate and radiating fin are made by aluminium.Substrate described in the utility model and radiating fin all adopt 6063 T5 high-quality aluminiums to make, and this aluminium purity reaches more than 98%, and capacity of heat transmission is strong, and density is little, low price, and the radiator heat-dissipation of making is effective.

Further, described substrate and the described radiating fin structure that is formed in one.

The utility model radiator, profile by design fastener and radiator realizes the general of radiator, radiator and main body bonding tightness directly have influence on radiating effect, so utilize fastener to increase the tightness of radiator and main body, have better promoted the radiating effect of radiator.

The beneficial effects of the utility model are: the utility model radiator, and without using heat-conducting glue, can directly be fixed on mainboard, and arbitrarily angledly all can place, radiator can not come off.
