Abstract

The utility model discloses a combined radiator. The combined radiator comprises a matrix and radiating fins, grooves are arranged on one surface of the matrix, the lower side edges of the radiating fins are plugged in the grooves, and the radiating fins are fastened and connected with the matrix and are equipped with ventilating channels. The combined radiator of the utility model is mainly used for the heat radiation of electric appliances and LED lamps, and has the advantages of being easy to process, having low device requirements, etc. Moreover, the independently processed devices are small in volumes and are easy to extrude, thereby effectively improving the qualified rate and avoiding waste. The radiating fins are equipped with the ventilating channels, so that the heat radiation area is large, the cross-ventilation is unobstructed, and the heat radiation effect is good.

Description

Combined radiator

Technical field

The utility model belongs to electric equipment heat sink technology field, specifically relates to a kind of knockdown aluminium radiator.

Background technology

Aluminium Radiator is widely used in technical fields such as TV, LED illumination.These radiators generally are at matrix radiating fin to be set, and the major part of heat distributes by fin.For satisfying the heat radiation requirement of high-power electric appliance equipment, the radiator volume that has is bigger, if the bigger radiator of this volume adopts the method processing of substrate and fin one coextrusion mold relatively more difficult, equipment is required high, and waste product appears easily, and causing waste, production efficiency is low.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of processing and fabricating of being convenient to, and is conducive to improve the radiator of qualification rate and production efficiency.

For solving the problems of the technologies described above, the utility model comprises matrix and radiating fin, and its design feature is that the one side of described matrix is provided with groove, and described radiating fin lower side is plugged in the groove, radiating fin and matrix are fastenedly connected, and radiating fin is provided with gas-permeable channels.

Preferably the ledge upper surface of described groove both sides is provided with crimp groove.

Another preferably the downside of described radiating fin be provided with wedge shape grafting tongue, grafting tongue and groove join, described gas-permeable channels is ventilative cavity.

After adopting said structure, because the one side of the utility model matrix is provided with groove, the lower side of radiating fin is plugged in the groove.Matrix and radiating fin shape respectively during making, then the groove of radiating fin and matrix are pegged graft, and utilize pressurized equipment along crimp groove ledge to be pressurizeed, and matrix and radiating fin are fastenedly connected get final product.Matrix and radiating fin secondary are pegged graft and are shaped, even if the bigger radiator of volume adds and also is easier to man-hour, equipment is required also low, handling ease.Because the device volume of processing is little respectively, extruding can effectively improve qualification rate easily, avoids waste.Radiating fin is provided with gas-permeable channels, and area of dissipation is big, and cross-ventilation is unimpeded, good heat dissipation effect.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is the utility model end view;

Fig. 2 is the utility model radiating fin schematic diagram;

Fig. 3 is the utility model matrix end view.

Embodiment

With reference to accompanying drawing, the utility model comprises matrix 1 and the radiating fin 2 of extrusion modling, matrix 1 and radiating fin 2 are made by aluminium, parallel many grooves 11 that are provided with on the one side of matrix 1, ledge 13 upper surfaces that constitute groove 11 both sides are provided with crimp groove 12, the lower side of radiating fin 2 is provided with wedge shape grafting tongue 21, grafting tongue 21 and groove 11 close proximity, thereby compress grafting tongue 21 by the hold down gag ledge 13 upper surfaces distortion that makes groove 11 both sides of exerting pressure, crimp groove 12 is grooves that hold down gag was exerted pressure after grafting tongue 21 was pegged graft with groove 11, can prevent the hold down gag skew of skidding, make radiating fin 2 pressurizeds even, thereby radiating fin 2 and matrix 1 are fastenedly connected.Every radiating fin 2 is provided with 3 gas-permeable channels 22, and gas-permeable channels 22 is the ventilative cavity that connects along radiating fin 2 length directions.

Claims (3)
