Abstract
The utility model discloses a heat dissipation unit and a laminated type electronic heat dissipation device. The heat dissipation unit comprises a connection block which is in contact with a heat source, and a heat dissipation tooth component which is fixedly connected with the connection block. One side of the connection block is provided with slots, and the other side of the connection block is provided with raised portions which correspond to positions of the slots and are in insertion matching with the slots. The laminated type electronic heat dissipation device is composed of a plurality of such heat dissipation units in an insertion manner. According to the utility model, the heat dissipation area of the heat dissipation device can be effectively increased, characteristics of novel structure, reasonable design, easy production as well as convenient and efficient installation are realized, advantages of low equipment investment and low material consumption are realized, and the rate of finished products can be fully guaranteed.
Description
Technical field
The utility model relates to a kind of electronic radiation device, relates in particular to a kind of heat-sink unit and laminated type electronic radiation device, belongs to technical field of electronic equipment.
Background technology
Development along with the electronic component high-frequency high-speed; The heat that electronic component produced is also more and more; The working temperature of electronic component constantly raises, and has had a strong impact on the useful life and the operation stability of each element, so must carry out radiating treatment to the electronic component in the work.Electronic component radiator adopts the aluminium extrusion forming method to make more at present, and general aluminum extruded material commonly used is AL6063, and it has good pyroconductivity and processability.But owing to receive the restriction of aluminium material itself and extrusion process; The thickness of radiator heat-dissipation fin and length ratio can not be above 1: 18; So in the confined space, be difficult to improve the area of dissipation of radiator; This just makes that heatsink weight is heavier, and the thicker and adjacent two radiating fin spacings of radiating fin are bigger.So aluminium extruded pressure type radiator heat-dissipation effect is poor, competent soaring day by day now high-frequency, the requirement of big power consumption electronic element radiating have been difficult to.
The utility model content
The technical problem that the utility model will solve; Provide a kind of heat-sink unit and laminated type electronic radiation device; Can effectively increase area of dissipation, its novel structure, reasonable in design, making convenience simple, quick for installation, and the equipment input is low, consumptive material is few, can fully ensure rate of finished products.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:
A kind of heat-sink unit, comprise the contiguous block that contacts with thermal source, with the radiation tooth that contiguous block connects firmly, contiguous block one side is provided with slot, the contiguous block opposite side is provided with convexity corresponding with slot position and that cooperate with the slot plug-in mounting.
As the improvement to the utility model, said slot and convexity are respectively two.
Another kind as to the utility model improves, and the surface of said radiation tooth is provided with ripple.
A kind of laminated type electronic radiation device is made up of a plurality of heat-sink unit plug-in mountings, and said heat-sink unit has the described characteristic of such scheme.
Owing to adopted technique scheme, the utility model compared with prior art, the technological progress that is obtained is:
The utility model is connected into radiator with single heat-sink unit through slot, convexity; Radiation tooth is fixed on the contiguous block, makes around the heat-radiating substrate that radiation tooth is distributed in to greatest extent with thermal source contacts, effectively increased the area of dissipation of radiator; And set up good and the heat transfer air channel of abundance; Make radiating efficiency reach the highest, solved the problem that radiator processing difficulties, equipment have high input, spillage of material is many that the radiation tooth high density distributes, reduced cost of manufacture.
The utlity model has novel structure, reasonable in design, making characteristics easily simple, quick for installation, be applicable on the electronic component that needs heat radiation.
