Description

Radiator

[technical field]

The utility model is about a kind of radiator, refers to that especially a kind of processing procedure is simple, snapping firm, is fit to automated production and the good radiator of radiating effect.

[background technology]

Along with developing rapidly of electronic industry, the speed of service of electronic components such as microprocessor is more and more faster, but, the high-frequency high-speed operation must make the heat of generation increase sharply thereupon, if untimely the distributing of these heats will cause the electronic component internal temperature sharply to raise, and then have a strong impact on the stability and the performance of electronic component operation, on the other hand, because large scale integrated circuit continuous advancement in technology, electronic heating size of component such as microprocessor are also more and more littler, this heat that will make the electronic component high-speed cruising produce is difficult to distribute more, and at present, heat dissipation problem has become influences the big obstacle of electronic industry to high-end development.

Because electronic component integrated level height, size is little, caloric value is big, rely on self-radiating can't effectively reduce temperature at all and satisfy job requirement, for this reason, industry installs a radiator additional at electronical elements surface usually and comes auxiliary heat dissipation.

The traditional heat-dissipating device normally is made up of substrate and fin, and the technology that is connected of its substrate and fin often adopts welding, bonding or crimping, and these all have shortcoming.As adopt welding manner, and complex process, cost is higher; If adopt bonding way, owing to be subjected to the restriction of adhesives, the one, manufacturability is poor, and the 2nd, complex process, the 3rd, curing time is long, and the 4th, bonding agent solidifies inside, back and has the air air gap, and thermal resistance is big, and heat transfer efficiency is low, and the 5th, the cost height; Chinese patent discloses the fin that disclosed for 1379465A number and the connected mode of substrate is the crimping mode, this substrate one side is provided with some grooves, fin insert in each groove and make by exerting pressure under between groove base plate deformation and from the both sides of groove it is clamped, thereby connect on substrate in the crimping mode.Yet be pressed into fin in the substrate by this kind crimping mode, because groove is more shallow, in use be easy to get loose, the snapping life-span is not long.

As shown in Figure 1, the insertion type radiator 30 that is disclosed for No. 353516 for the Taiwan patent announcement.This radiator 30 comprises a pedestal 31, the plate face equal intervals of these pedestal 31 1 sides is provided with the slot 32 of some parallel its lateral margins, respectively this slot 32 is plugged with a fin 33 respectively, form portion 34 between a groove between adjacent two slots 32, portion 34 respectively is provided with a V-type groove 35 every between a groove, thereby these V-type groove 35 generation plastic deformations make fin 32 be intercalated in the slot 32 with fashion of extrusion when fin 33 inserts slot 32.Above-mentioned fin 33 engages with pedestal 31 with fashion of extrusion, the two must exist the space to make it contact not exclusively, even slot 32 the insides are all inserted in fin 33 ends, the amount of plastic deformation of V-type groove 35 is also insufficient, when like this, fin 33 is on being installed to electronic component or in use will run-off the straight or come off.

Could solve above problems so need good structural design, and then satisfy the needs of using.

[summary of the invention]

The purpose of this utility model is: provide that a kind of processing procedure is simple, snapping firmly, be fit to automated production and the good radiator of radiating effect.

The purpose of this utility model realizes by following technical proposal: a kind of radiator, comprise a pedestal and be assembled in a plurality of fin on the pedestal, this pedestal is provided with some through holes, and each fin is provided with correspondence and passes above-mentioned through hole and the bent lug that adheres on the pedestal.

Compare with prior art and the utlity model has following advantage: by in lug being set on the fin, corresponding through hole being set on pedestal, and then the lug that makes fin passes the mutual buckle of through hole of through hole bending back and pedestal, and this setting has overcome previous use welding manner complex process and the high shortcoming of cost; Overcome the shortcoming that the bonding way manufacturability is poor, curing time is long and cost is high; Overcome the unstable shortcoming of crimping mode snapping; Make the firm and good heat dissipation effect of this radiator snapping.

[embodiment]

Please refer to Fig. 2 and shown in Figure 3, radiator of the present utility model mainly comprises pedestal and one group of fin 4, and wherein pedestal comprises pedestal 1 and lid 2.

Each fin 4 is a sheet metal punch forming, and its relative two ends are provided with four symmetrical square lugs 42, and wherein the height of this lug 42 is greater than the thickness of pedestal 1.

Pedestal 1 and lid 2 are respectively a metallic plate punch forming, and this pedestal 1 and lid 2 be arranged in parallel, and this pedestal 1 and lid 2 are respectively equipped with corresponding square through hole 10,20 corresponding to lug 42 positions of fin 4.The sectional area size of this through hole 10,20 and the sectional area sizableness of lug 42.Be provided with the groove 22 that connects with through hole 20 in through hole 20 1 ends on the lid 2.

During assembling, at first the lug 42 of fin 4 is aimed in the through hole 10 that inserts corresponding pedestal 1; Make the through hole 20 of lid 2 aim at the lug 42 of corresponding fin 4 then, lid 2 is parallel to pedestal 1 places on the fin 4 and make lug 42 insert lids 2 corresponding through holes 20; Thereby the lug 42 that will insert pedestal 1 at last is along the direction bending that is parallel to pedestal 1 and adhere on the bottom surface of pedestal 1 and form kink (not shown), thereby the lug 42 that will insert lid 2 again is along the direction bending that is parallel to lid 2 and adhere in the groove 22 of lid 2 and form kink 46, wherein the size of this kink 46 is with groove 22 sizableness of lid 2, the thickness of kink 46 is less than or equal to the height of groove 22, kink 46 can be fixing with pedestal 1 and lid 2 with fin 4, and fin 4 can not got loose with pedestal 1 and lid 2.

In use, heat-generating electronic elements (not shown) is adhered on the end face of lid 2, fan (not shown) is placed fin 4 side vertical with pedestal 1 direction.

In the present embodiment, also can offer the groove that connects with through hole 10 in through hole 10 1 ends on the bottom surface of pedestal 1, bend in this groove after passing through hole 10 with through hole 10 corresponding lugs 42.The lug 42 at fin 4 two ends also can be symmetrical arranged, and for example the one end is provided with a lug 42, and the other end is provided with two lugs 42.

In another execution mode of the present utility model, pedestal include only pedestal 1 or lid 2 the two one of, this pedestal is provided with through hole, pedestal offers the groove that connects with through hole in through hole one end, one end of fin 4 is provided with and the corresponding lug 42 of through hole, bending placed groove to form kink after lug 42 passed through hole, and the thickness of this kink is less than or equal to the height of groove.

The shape of the utility model projection 42 is not limited to square, and it can be other suitable shape, as triangle, trapezoidal etc.In addition, the size of pedestal through hole and groove and shape change according to the size and the shape of respective tab.
