Description

A kind of LED radiators

Technical field

The utility model is related to technical field of heat dissipation, and in particular to a kind of LED radiators.

Background technology

LED class household electrical appliances are more and more with device, while the radiating of LED is increasingly paid attention to by people now, meeting in LED operation Substantial amounts of heat is produced, these heats can not be distributed in time, Embedding Material will be caused aging, chip light decay acceleration etc. is a series of Problem, the bad junction temperature of radiating will be raised, and temperature often reduces by 10 DEG C of life-spans and can extend 2 times.Therefore, existing LED is equipped with Have a radiator, PCB plates directly with radiator good contact, the heat produced during LED lamps are worked dissipates.It is existing to dissipate Hot device generally includes base plate, top board and the multi-disc fin being vertical between base plate, top board, is formed between adjacent fin Air channel, it is clear that the radiator heat-dissipation effect of this spline structure is simultaneously bad.Another is only base plate and to be vertical on base plate Multi-disc fin, form air channel between adjacent fin, although such structure is so that heat easily rises discharge, It is the easy temperature distortion of such structure fin, changes the structure of heat dissipation channel, so that in use, radiating Performance is gradually deteriorated, it is impossible to play good thermolysis.

The content of the invention

The purpose of this utility model is for above-mentioned deficiency of the prior art, there is provided a kind of LED radiators, by closing The structure setting of reason, makes radiating effect more preferably, while horizontally disposed fin can reduce the accumulation of dust, affects radiating effect Really.

The purpose of this utility model is achieved through the following technical solutions：

A kind of LED radiators, including conducting strip, radiating fixed mount, radiating tube and groups of fins, it is characterised in that：Institute State the central part of radiating tube to be fixedly connected with conducting strip side by the fixed mount that radiates, the two ends of the radiating tube and groups of fins It is flexibly connected, the fin that the groups of fins is parallel to each other including several.

Wherein, the fin side protrusion is provided with several louvres, is connected by louvre between fin.

Wherein, the louvre includes bend and the vertical tube part being connected with fin.

Wherein, the fin both sides are provided with support block.

Wherein, the another both sides of the fin are additionally provided with several scarce portions.

Wherein, the fin center is hollow setting.

Wherein, the radiating fixed mount side is provided with some tube seats coordinated with radiating tube, if opposite side is provided with Dry thermal conductive cavity.

Wherein, it is provided with metallic sponge in the thermal conductive cavity.

The beneficial effects of the utility model：A kind of LED radiators of the present utility model, by arranging conducting strip, radiating Fixed mount, radiating tube and groups of fins, are radiated in the heat transfer groups of fins that effectively can be produced LED, are increased Radiating efficiency, while being provided with the accumulation that horizontal fin is avoided that dust, it is ensured that radiating effect.

Description of the drawings

Utility model is described further using accompanying drawing, but the embodiment in accompanying drawing is not constituted to of the present utility model What is limited, for one of ordinary skill in the art, on the premise of not paying creative work, can be with according to the following drawings Obtain other accompanying drawings.

Reference includes：It is 1 conducting strip, 2 radiating fixed mounts, 3 radiating tubes, 4 fin, 5 louvres, 6 bends, 7 straight Cylinder portion, 8 support blocks, 9 lack portion, 10 tube seats, 11 thermal conductive cavities, 12 metallic sponges.

Specific embodiment

With the following Examples and accompanying drawing is further described to the utility model.

As depicted in figs. 1 and 2, a kind of LED radiators of the present utility model, including conducting strip 1, radiating fixed mount 2, dissipate Heat pipe 3 and groups of fins, the central part of the radiating tube 3 is fixedly connected by the fixed mount 2 that radiates with the side of conducting strip 1, described The two ends of radiating tube 3 are flexibly connected with groups of fins, the groups of fins be parallel to each other including several and level fin 4.A kind of LED radiators of the present utility model, by arranging conducting strip 1, radiating fixed mount 2, radiating tube 3 and groups of fins, Radiated in the heat transfer groups of fins that effectively can be produced LED, increased radiating efficiency, while being provided with horizontal Fin 4 is avoided that the accumulation of dust, it is ensured that radiating effect.

As shown in figure 3, the side of fin of the present utility model 4 protrusion is provided with several louvres 5, between fin 4 Connected by louvre 5.Wherein, the louvre 5 includes the vertical tube part 7 of the bend 6 being connected with fin 4 and outermost end. Radiating tube 3 passes through louvre 5, contacts with the vertical tube part 7 of louvre 5 and transfers heat on fin 4, while in louvre 5 Upper setting bend 6 and vertical tube part 7, can be such that radiating tube 3 contacts with fin 4 more preferably, transmit good heat dissipation effect.

As shown in Fig. 3, Fig. 4 and Fig. 5, the both sides of fin of the present utility model 4 are provided with support block 8.Support block 8 is located at and dissipates The outermost end of the both sides of backing 4, because the area of fin 4 is big and thin, only connects, loosely between fin 4 by louvre 5 Gu, it is easily curved under gravity to tear open, and the heat between fin 4 is uneven, is provided by support block 8, can be effective Heat between the average fin 4 in ground, increases radiating effect.Wherein, the center of fin 4 is hollow setting, due to the face of fin 4 Product is larger, and the fin 4 on upper strata can affect the heat spreader of lower floor's fin 4, and by arranging scarce portion 9 lower floor's fin can be increased 4 radiating effect.Wherein, the another both sides of fin 4 are additionally provided with several scarce portions 9, and the scarce portion 9 of several fin 4 forms one The heavy connection of pipe of individual matrix, heavy connection of pipe can treat that radiating tube 3 is radiated with tubulose, so as to increasing the utilization rate of radiator.

Wherein, radiating fixed mount 2 side is provided with some tube seats 10 coordinated with radiating tube 3, and opposite side is arranged There are several thermal conductive cavities 11.Wherein, it is provided with metallic sponge 12 in the thermal conductive cavity 11.Tube seat 10 be U-shaped setting, can with dissipate Heat pipe 3 is used cooperatively, and is snapped in radiating tube 3 and is not deviate from tube seat 10, and radiating tube 3 is contacted more preferably with radiating fixed mount 2, Increase transmission efficiency.The thermal conductive cavity 11 of opposite side is provided with metallic sponge 12, and metallic sponge 12 is loose structure, preferably The heat for treating heat dissipation equipment can be absorbed, increases radiating effect.

Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality With the restriction of novel protected scope, although having made to explain to the utility model with reference to preferred embodiment, this area it is general It is logical it will be appreciated by the skilled person that can modify to the technical solution of the utility model or equivalent, without deviating from this The spirit and scope of utility model technical scheme.
