Abstract

A radiator comprises a plurality of radiating fins and one or more than one heat conduction copper pipe, wherein the lower edge of each radiating fin forms a horizontally vertical folding edge that forms a notch for holding the copper pipe; the approximate middle of the fin is provided with at least one ventilation hole and besides, each fin is provided with a horizontally matched connecting device; the heat conduction pipe is a 'U'-shaped pipe, in which a vertical rod is embedded in the notch of the folding edge of each fin and protruded out of one side of the notch and beaten flat to form a plane so that the plane and the folding edge are on the same plane; and another vertical rod of the copper pipe penetrates through each radiating fin. After the plurality of fins are combined, the folding edge can form a contact surface in direct contact with a heating body, and simultaneously, the heat conduction copper pipe is also on the contact surface, thus leading to be more simplified in structure and available for small volume of the radiator. The heat conduction copper pipe allows heat to be transferred to a position of each fin away from the folding edge in time. The arrangement of the ventilation hole on each fin can realize the cold and hot convection of hot air, reduce heat concentration and effectively improve the radiating effect of the whole radiator.

Description

A kind of radiator

Technical field

The utility model is the radiator that is applied to electronic equipment about a kind of.

Background technology

Electronic product as computer, LED electroluminescent lamp, power supply etc., guarantees the heat radiation that it is good, is the necessary means that improves its useful life and operate as normal efficient, and therefore, various radiators arise at the historic moment.

Be a kind of radiator commonly used in the prior art as shown in Figure 1, it comprises a base 1 ' that contacts with heater, the radiating fin 2 ' of a plurality of vertical arrangements, and two heat-conducting copper pipes 3 ' of connection base 1 ' and radiating fin 2 ', this heat-conducting copper pipe 3 ' is made as " U " type, one cross bar 31 ' is to be fixed in the groove 11 ' of base 1 ' contact-making surface, two montants 32 ' are vertical being located in the radiating fin 2 ' in addition, utilize the good thermal conductivity of aluminium matter base 1 ' and copper pipe 3 ', the heat of heater can be conducted to timely each radiating fin 2 ' and dispel the heat.

But each radiating fin 2 ' is holistic lamellar body in this radiator, and copper pipe 3 ' is the nearly four jiaos of places that are positioned at radiating fin 2 ', then the middle part of lamellar body concentrates heat effectively to shed easily, cause the radiating effect of this radiator not good, the independence setting that contacts base simultaneously also can increase the volume and the component costs of this radiator.

The utility model content

The purpose of this utility model provides that a kind of volume is little, the radiator of excellent in heat dissipation effect.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of radiator, comprise several radiating fins and one and more than one heat-conducting copper pipe, wherein: the following laterally vertical flanging that forms of each fin, form the short slot of ccontaining copper pipe on this flanging, nearly medium position at this fin is provided with at least one ventilation hole, is provided with the jockey of horizontal cooperation in addition on each fin; Heat-conducting copper pipe is " U " type pipe, and wherein a montant is to be embedded in the short slot of each fin flanging, and the protruding side of exposing short slot of this montant flattens and form the plane, to make this plane and flanging in one plane; Another montant of copper pipe passes each fin.

Described each fin is a lamellar body, and jockey is to be provided with hole clipping at nearly lamellar body place, flanging middle part, and is extended with a grab that cooperates with hole clipping at this flanging middle part front end.

The lamellar body top horizontal expansion of described each fin have one with the rightabout coordinating block of flanging, the nearly lamellar body of this coordinating block place is provided with hole clipping, and is extended with a grab at the coordinating block front end, also is to form the jockey that the mutual clamping of adjacent fin cooperates.

After adopting such scheme, radiator of the present utility model is because the formation of fin flanging, a plurality of fins are after combination, flanging can form a contact-making surface, and the heat-conducting copper pipe that has the plane simultaneously also is on this contact-making surface, and then heater directly contacts with this contact-making surface, its heat can directly reach on the fin, need not the contact base is set separately, make heat spreader structures more simplify, but the volume miniaturization; Add the setting of " U " type heat-conducting copper pipe, can make heat reach the position of each fin timely away from flanging, and the setting of ventilation hole on each fin, can reduce heat concentrates in the heat at fin middle part, this ventilation hole can be realized the cold and hot convection current of hot-air, reduce heat and concentrate, the temperature of fin is reduced greatly, so effectively the radiating effect of entire radiator.

Embodiment

Below in conjunction with drawings and the specific embodiments the utility model is elaborated,

To shown in Figure 4, radiator of the present utility model comprises several radiating fins 2 and one and more than one heat-conducting copper pipe 3 as Fig. 2.

Each fin 2 is a lamellar body, its following laterally vertical flanging 21 that forms, form the short slot 22 of ccontaining copper pipe 3 on this flanging 21, on lamellar body, also be provided with the through hole 23 that cooperates copper pipe 3 in addition, nearly medium position at this lamellar body is provided with ventilation hole 24, and this ventilation hole 24 is provided with at least one, is provided with two in this scheme, a rectangular opening that is in lamellar body central authorities, another is the circular hole that is located at the rectangular opening below; Nearly lamellar body place is provided with hole clipping 25 at flanging 21 middle parts, and is extended with a grab 26 that cooperates with hole clipping 25 at these near side (ns) 21 middle part front ends; The horizontal expansion of the top of lamellar body have one with flanging 21 rightabout coordinating blocks 27, these coordinating block 27 nearly lamellar body places are provided with hole clipping 271, and are extended with a grab 272 at coordinating block 27 front ends.The setting of hole clipping 25,271 and grab 26,272 herein is jockeys that 2 mutual clampings cooperate as adjacent fin.

Heat-conducting copper pipe 3 is " U " type pipe, and wherein a montant 31 is to be embedded in the short slot 22 of each fin 2 flanging 21, and these montant 31 protruding sides of exposing short slot 22 flatten and form plane 311, to make this plane 311 and flanging 21 in one plane; Its another montant 32 is to pass on each fin 2 to be combined together with each fin 2 behind the through hole 23, so just forms a radiator.

Because the formation of fin 2 flangings 21, a plurality of fins 2 are after combination, flanging 21 can form a contact-making surface, the heat-conducting copper pipe 3 that has plane 311 simultaneously also is on this contact-making surface, then heater directly contacts with this contact-making surface, and its heat can directly reach on the fin 2, need not to be provided with separately the contact base, make heat spreader structures more simplify, but the volume miniaturization; Add the setting of " U " type heat-conducting copper pipe 3, can make heat reach the position of each fin 2 timely away from flanging 21, and the setting of ventilation hole 24 on each fin 2, can reduce heat concentrates in the heat at fin 2 middle parts, this ventilation hole 24 can be realized the cold and hot convection current of hot-air, reduce heat and concentrate, the temperature of fin 2 is reduced greatly, so effectively the radiating effect of entire radiator.
