Description
Technical field
The utility model belongs to electronic technology field, is specifically related to a kind of cooling fin for electronic element radiating.
Background technique
Cooling fin is a kind of device that the easy heat-generating electronic elements in electric appliance radiate, mostly by aluminium alloy, brass or bronze
It is made into plate, sheet, splintery etc. makes in Switching Power Supply if cpu central processing unit will use sizable cooling fin in computer
Power tube, output rectifier diode constant power heater element are required to using cooling fin.
Either any material, the cooling fin of any shape will be contacted closely with the object that radiate is needed when use,
Contact area size directly affects heat dissipation effect；Cooling fin will affect heat dissipation effect and device with the mode assembled by thermal dissipating object
The assembly of part.
In the prior art, cooling fin is fixed by screws on electronic component, and for convenient for assembly, cooling fin and switch electricity
Incomplete matching, switching tube and cooling fin assemble rear easily skew, need manually again the switching tube of source mainstream in shape
It sets right, influences production efficiency.
Utility model content
The utility model is intended to provide a kind of cooling fin, to solve the problems, such as easy skew after existing cooling fin assembling.
Concrete scheme is as follows: a kind of cooling fin, including a heat-radiating substrate, which is equipped with mounting hole；
Two limit raised lines are additionally provided on the one side of the heat-radiating substrate, two limit raised lines are oppositely arranged, to cooperatively form one
Locating groove.
Further, a radiator shutter is further respectively had on the two sides of the locating groove, the heat-radiating substrate；Two heat dissipations
Blade protrudes out the limit raised line upper end, and each radiator shutter is correspondingly connected to the limit raised line closed on.
Further, two closing raised lines are additionally provided on the heat-radiating substrate, the two closing raised lines are respectively arranged on the locating groove
Rear and front end, to close the locating groove.
The utility model has the advantages that the cooling fin of the utility model, by the way that two limit raised lines are arranged on heat-radiating substrate, by limit raised line
Adaptation forms locating groove, which adapts to the electronic package size to be radiated setting, and then realizes
Cooling fin is fixedly secured；Cooling fin matches preferably with by thermal dissipating object, easily slides after assembling, does not need manually to correct, can be straight
It connects and is assembled on circuit board.
Meanwhile the setting of this kind limit raised line, heat-conducting silicone grease is applied in cooling fin and between thermal dissipating object, is limited in two sides
Under the action of, heat-conducting silicone grease can be applied directly on contact surface, will not flow to non-contact face, reduce heat-conducting silicone grease dosage, thermally conductive
It is more preferable that silicone grease is coated with Homogeneouslly-radiating effect.
In further technical solution, this kind limits the setting of raised line, by radiator shutter and by the side of thermal dissipating object
Keep apart, be conducive to the flowing of radiator shutter two sides gas, the heat dissipation effect of cooling fin entirety is more preferable.
Detailed description of the invention

Fig. 2 shows the utility model embodiment structural schematic diagrams；
Fig. 3 shows Fig. 2 front view.
Specific embodiment
To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings are in the utility model discloses
A part of appearance mainly to illustrate embodiment, and can cooperate the associated description of specification former come the running for explaining embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and sheet are practical new
The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
As shown in connection with fig. 1, the cooling fin 1 of the prior art a comprising heat-radiating substrate 10, the one side of the heat-radiating substrate 10
On be fixed with electronic component 2；And perpendicular to the heat-radiating substrate 10, which further includes multiple radiator shutters 11, wherein Gu
On the one side of the fixed electronic component 2, two radiator shutters 11 are respectively arranged on the outer of heat-radiating substrate 10, according to assembly needs,
Each radiator shutter 11 has one to shake gap 110 between the electronic component 2, and electronic component 2 is generally by one
Screw is mounted on heat-radiating substrate 10, thus easily occur 1 opposing electronic 2 beat of element of cooling fin the problem of.
In conjunction with shown in Fig. 2 and Fig. 3, this embodiment offers a kind of improved cooling fins 1 comprising a heat-radiating substrate
10, which is equipped with mounting hole 12, specifically, the mounting hole 12 is threaded hole, for installing electronic component；
Two limit raised lines 13 are additionally provided on the one side of the heat-radiating substrate 10, the two limit raised lines 13 are to be oppositely arranged, with
The upper side of the heat-radiating substrate 10 is cooperated to form the locating groove 130 of a U-shaped.
Meanwhile a radiator shutter 11 is further respectively had on the two sides of the locating groove 130, the heat-radiating substrate 10；Two should
The upper end of radiator shutter 11 protrudes out 13 upper end of limit raised line, and each radiator shutter 11 is correspondingly connected to the limit closed on
Position raised line 13, wherein preferred, which is an integral structure.
The setting of the limit raised line 13, height original are less than the thickness of electronic component, do not influence simple on heat-radiating substrate 10
Electronic component is just installed；And the width of locating groove 130 adapts to the width setting of electronic component, realizes determining for electronic component
Position solves the problems, such as 1 skew of cooling fin；It, generally need to be in the heat-radiating substrate 10 of cooling fin 1 and by the hot object of fan according to process requirements
Heat-conducting silicone grease is applied before body, to guarantee heat dissipation effect, due to two limit raised lines 13 and by thermal dissipating object tight fit, and then is being connect
Contacting surface coats certain heat-conducting silicone grease, heat-conducting silicone grease even spread contact surface under pressure, avoids and flows to that side is non-to be connect
The problems such as contacting surface causes to waste, dirty.
It should be understood that in other further prioritization schemes, it is additionally provided with two closing raised lines on the heat-radiating substrate, two
The closing raised line is respectively arranged on the locating groove rear and front end, to close the locating groove, forms one and adapts to electronic component
Groove, the effect for sealing heat-conducting silicone grease is more preferable, and heat transfer efficiency is higher；Alternatively, the limit raised line of locating groove two sides and heat dissipation
The setting of spacing with blades certain distance further increases the heat dissipation area of cooling fin, and insulating electron element side wall and heat dissipation leaf
Piece, better heat-radiation effect.
Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered
