Abstract

The utility model relates to a water-cooled vehicular light-emitting diode heat abstractor, which is an electromechanical product. The utility model comprises a light-emitting device and a heat abstractor, wherein the light-emitting device comprises a light-emitting element and a base board, the heat abstractor comprises a water-raising equipment, a water-storage equipment, a liquid guiding element, and a radiator. The radiator is arranged on one side of the light-emitting device, which comprises a front-board, a middle-board, and a back-board. Grooves are formed on the front-board, the middle-board, and the back-board, which separately form a passage, a liquid inlet, and a liquid outlet. The liquid form the water storage equipment is injected into the passage of the radiator via the water-raising equipment and the liquid guiding element, thereby achieving the purpose of efficient heat dissipation. The radiator arranged on one side of the light-emitting device can be used for a headlight structure of loading attachments, which can avoid damage of the light-emitting device caused by high power, thereby increasing using safety and practicability.

Description

Water-cooled automobile-used LED heat abstractor

Technical field

The utility model relates to electrical category, particularly a kind of water-cooled automobile-used LED heat abstractor.

Background technology

As shown in Figure 1, general automobile-used light-emitting device A, do not have heat abstractor is set, it causes the problem of damaging light-emitting device A because of power is too high, and its radiating mode is if easily cause heat radiation not exclusively with free convection, and, need be improved if easily produce problems such as noise and life cycle weak point with fan.

The utility model content

The purpose of this utility model is to provide a kind of water-cooled automobile-used LED heat abstractor, and having solved present automobile-used light-emitting device does not have heat abstractor, easily causes and damages light-emitting device because of power is too high, and use uneasy congruent problem.

The technical solution of the utility model is: be made of light-emitting device and heat abstractor, wherein, this light-emitting device comprises light-emitting component and substrate, this heat abstractor comprises the equipment of pumping up water, water storage device, drain element and radiator, one side of this light-emitting device is provided with a radiator, this radiator comprises positive plate, middle plate and backboard, this positive plate, middle plate and backboard depression are fluted, and be combined into passage, inlet and liquid outlet, the liquid of water storage device reaches the purpose of efficiently radiates heat by the passage of the equipment of pumping up water via drain element injection radiator;

Light-emitting component can be made as light-emittingdiode, based on halogen bulb, hernia bulb and relevant light-emitting component; Substrate can be made as the material of copper material, aluminium material, alloy material, ceramic material and the relevant high heat conduction of tool, high radiating effect; Light-emitting device and heat abstractor can be applicable to take advantage of the Headlamp structure that carries device, and the water storage device of this heat abstractor can utilize the water storage device of taking advantage of year device itself.

Advantage of the present utility model is: a side of light-emitting device is provided with radiator, can be used in to take advantage of the Headlamp structure that carries device, is difficult for causing because of power is too high damaging light-emitting device, increases the security of using, and is practical.

The specific embodiment:

Shown in accompanying drawing 2 and accompanying drawing 3, the utility model is made of light-emitting device B and heat abstractor C; Wherein this light-emitting device B comprises light-emitting component B1 and substrate B2, and this heat abstractor C comprises the equipment D that pumps up water, water storage device E, drain element F and radiator G;

The side of light-emitting device B is provided with a radiator G, and this radiator G comprises positive plate G1, middle plate G2 and backboard G3; Wherein positive plate G1, middle plate G2 and backboard G3 cave in respectively fluted G11, G21, G31, this groove G11, G21, G31 are combined into a passage G4, inlet G5 and liquid outlet G6, inject the passage G4 of radiator G by the liquid of equipment D that pumps up water via drain element F, but make it reach the purpose of efficiently radiates heat water storage device E.

As shown in Figure 4, light-emitting component B1 is encapsulated in default being embedded in the space of substrate B2, in the hard solder mode substrate B2 and radiator C are integrated admittedly again, wherein light-emitting component B1 can be made as light-emittingdiode, based on halogen bulb, hernia bulb and relevant light-emitting component, and this substrate B2 can be made as the material of copper material, aluminium material, alloy material, ceramic material and relevant high heat conduction, high radiating effect;

Inlet G5 has engaged a drain element F respectively with liquid outlet G6 place, this drain element F is serially connected with pump up water equipment D and water storage device E in addition, and it forms the path of a series connection, by this, when the equipment D that pumps up water starts running, make the liquid of water storage device E do flowing of a circulation via the path of series connection;

Radiator G does an absorption with the heat that light-emitting component B1 is produced, the liquid that flows into via inlet G5 cools off in the passage G4 of radiator G again, the liquid that then will have temperature again is expelled to water storage device E by liquid outlet G6, the heat that radiator G is absorbed that circulates is so again and again taken away, and makes light-emitting device B1 reach the purpose of efficiently radiates heat.

Shown in accompanying drawing 5 and accompanying drawing 6, light-emitting device B and heat abstractor C can be applicable to take advantage of the Headlamp structure that carries device H, and this heat abstractor C can utilize and take advantage of the retaining H1 that carries device H, and be provided with tap H4 at inlet H2 and the liquid outlet H3 place of water storage device H1, this tap H4 engages has a drain element F to be connected with the equipment D that pumps up water in addition, but make it reach the effect of water-cooled heat radiation, by this, when the equipment D that pumps up water starts running, make the liquid of water storage device H1 do flowing of a circulation, but make it reach the purpose of efficiently radiates heat via the path of series connection.
