Abstract

The utility model discloses a novel LED (light emitting diode) heat dissipater, wherein through the arrangement of a first plug disc and a second plug disc, by the adoption of a plug piece type structure, a sufficient gap is formed between pieces; air convection is formed by using the gap, heat dissipation process is carried out on an aluminum substrate timely and effectively; meanwhile, an internal cylinder is additionally arranged in the heat dissipater; a power supply is separated from the heat dissipater through the internal sleeve, so that the situation that the power supply is burnt out due to excess temperature when the power supply is in contact with an aluminum piece and the aluminum substrate directly is avoided, therefore the power supply is effective to protect, the service lives of LED lamps are prolonged; compared with the conventional LED lamp heat dissipater, the heat dissipation effect is improved by 30-50%; meanwhile, the plug piece type heat dissipater has the characteristics of simple structure and convenience for disassembly.

Description

A kind of New LED radiator

Technical field

The utility model relates to a kind of heat abstractor, relates in particular to a kind of radiator of LED lamp.

Background technology

The LED lamp has advantages such as energy-saving and environmental protection, long service life, low consumption as novel lighting source, has been widely used in fields such as domestic lighting, commercial lighting, highway lighting, industrial and mineral illumination.

Along with the LED technology rapid development, caloric value and the heat flow density of LED increase considerably, and the heat radiation of LED is related to the luminous efficiency and the service life of LED lamp.One of existing heat dissipation technology is to use the liquid cooling technology to dispel the heat, yet the liquid cooling system volume is big usually, and itself there is potential safety hazard in the liquid cooling technology, in case leaking appears in liquid cooling system, will cause LED to damage; Two of existing heat dissipation technology is to use hot pipe technique, and the hot pipe technique heat transfer efficiency is very high, and is very little but general heat pipe such as circular heat pipe and electronic equipment heating face get contact area, causes equivalent thermal resistance big, makes to use to be very limited.

The utility model content

The technical problem that the utility model will solve is to overcome deficiency of the prior art, proposes the Novel LED light radiator of a kind of good heat dissipation effect, simple in structure, convenient disassembly.

For realizing above-mentioned purpose, the technical solution of the utility model is: a kind of Novel LED light radiator is characterized in that; Comprise that first inserts dish, the second slotting dish, a plurality of inserted sheet, said first inserts dish is provided with internal tooth and external tooth, and said second inserts dish only is provided with external tooth; Said inserted sheet bottom is provided with draw-in groove; It is suitable that the external tooth that coils is inserted in the outer end of said draw-in groove and first, and the internal tooth of the inner of said draw-in groove and the first slotting dish and the external tooth of the second slotting dish are chimeric mutually, are scattered with the heat radiation through hole on the said inserted sheet.

Bore after said inserted sheet compresses becomes the form of amplifying gradually from top to bottom.

Said inserted sheet top is vertically installed with clip.

Also include inner core, said inner core upper level is provided with groove, and is suitable with the clip at inserted sheet top, is used to place power supply, and power supply and radiator are isolated.

The tube bottom optional position is provided with wire hole in described, is used to install the LED light fixture.

Said first inserts dish is provided with and the corresponding delivery outlet in inner core bottom wire hole.

The beneficial effect of the utility model: the utility model is provided with first and inserts the dish and the second slotting dish, adopts the structure of blade inserting, and making has enough gaps between sheet and the sheet, utilize the gap to make cross-ventilation; Timely and effective with the aluminium base heat radiation, simultaneously, this radiator has increased inner core; Utilize inner core that power supply and radiator are isolated, avoid power supply directly to contact with aluminium base and cause the power supply temperature too high and burn, effectively protect power supply with the aluminium flake of radiator; Prolonged the service life of LED lamp, compared traditional LED lamp radiator, radiating effect has improved 30%-50%; Simultaneously, fin-inserted radiator simple in structure, convenient disassembly.

Below will combine accompanying drawing and embodiment, the utility model will be carried out comparatively detailed explanation.

The specific embodiment

Like Fig. 1,2,3,4, shown in 5; A kind of Novel LED light radiator is characterized in that, comprises that first inserts dish 1, second and insert dish 2, a plurality of inserted sheet 3; Said first inserts dish 1 is provided with internal tooth 11 and external tooth 12; Said second inserts 2 on dish is provided with external tooth 21, and said inserted sheet 3 bottoms are provided with draw-in groove 4, and the external tooth 12 of the outer end of said draw-in groove 4 and the first slotting dish 1 is suitable; The external tooth 21 of the internal tooth 11 of the inner of said draw-in groove 4 and the first slotting dish 1 and the second slotting dish 2 is chimeric mutually, is scattered with heat radiation through hole 5 on the said inserted sheet 3.

Bore after said inserted sheet 3 compresses becomes the form of amplifying gradually from top to bottom.

Said inserted sheet 3 tops are vertically installed with clip 6.

Also include inner core 7, said inner core 7 upper levels are provided with groove 8, and are suitable with the clip 6 at inserted sheet 3 tops, are used to place power supply, and power supply and radiator are isolated.

Optional position, described inner core 7 bottom is provided with wire hole 9, is used to install the LED light fixture.

Said first inserts dish 1 is provided with and the corresponding delivery outlet 10 in inner core 7 bottom wire holes.

Operation principle: in LED lamp when work,, the air in the lamp house rises, the gap between the inserted sheet of will flowing through during through radiator; The heat that the LED tube core produces is taken away, and temperature raises behind the radiator because the air in the lamp house is flowed through, and flows to outside the lamp house; Cold air in the lamp house will rise and replenish in the radiator, thereby near radiator, form cross-ventilation, simultaneously; Radiating effect is accelerated in the heat radiation through hole guiding circulation of air of scattering on the inserted sheet.

The utility model is provided with first and inserts the dish and the second slotting dish, adopts the structure of blade inserting, and making has enough gaps between sheet and the sheet, utilize the gap to make cross-ventilation; Timely and effective with the aluminium base heat radiation, simultaneously, this radiator has increased inner core; Utilize inner core that power supply and radiator are isolated, avoid power supply directly to contact with aluminium base and cause the power supply temperature too high and burn, effectively protect power supply with the aluminium flake of radiator; Prolonged the service life of LED lamp, compared traditional LED lamp radiator, radiating effect has improved 30%-50%; Simultaneously, fin-inserted radiator simple in structure, convenient disassembly.

Above embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineers and technicians in this area make the technical scheme of the utility model all should fall in the protection domain that claims of the utility model confirm.

The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
