Abstract
This utility model relates to a thermal tube radiation assembly of the illumination diode car clamp, which is characterized in that the thermal tube radiation assembly comprises a heat sink, a heat tube and a longitudinal ribbed radiator. The heat sink is a heat conduction block connected with one terminal of the heat tube, and the other terminal of the heat tube is connected with the longitudinal ribbed radiator which is equipped in positions in the car that is suitable for heat dissipation. The center of the heat tube is a hollow vacuum tube body with its interior wall equipped with a liquid absorption core with operation liquid. After experiments, this utility model is proved to reduce the components temperature to lower than 80 percent of the original value after the installation of the radiation components on rear fog lamps of PASSAT concept cars.
Description
Technical field
The utility model relates to a kind of radiating subassembly, the heat pipe type radiating subassembly that particularly a kind of light-emitting diode (LED) car lamp is used.
Background technology
Utilize at present that light-emitting diode is long because of its life-span as the light source of car light, luminous efficiency is high is applied, but, the electrical power more than 70% of light-emitting diode changes into heat because remaining, cause the temperature of luminescent device to raise, can cause luminous efficiency decline, photochromic variation and even inefficacy, also can cause consequences such as encapsulating material variation, device architecture damage simultaneously.Light-emitting diode luminous intensity distribution plate as vehicle light illumination is in the space of a narrow and small sealing, heat dissipation environment is very poor, the heat radiation of existing car light generally is the natural heat dissipation that utilizes its lamp housing, therefore heat radiation requirement in the time of can't satisfying LED luminous intensity distribution plate and use in car light needs the design specialized radiator structure.
Summary of the invention
The purpose of this utility model is the existing problem that can't satisfy the heat radiation of light-emitting diode luminous intensity distribution plate of natural heat dissipation that car light utilizes lamp housing in the solution prior art, the heat pipe type radiating subassembly that provides a kind of light-emitting diode (LED) car lamp to use.The heat pipe type radiating subassembly that the utility model design light-emitting diode (LED) car lamp is used, it is characterized in that: the heat pipe type radiating subassembly is made up of heat sink, heat pipe and the heat radiation of longitudinal rib shape, heat sink is a heat conduction block, one end of heat pipe is connected with heat sink, the other end of heat pipe connects the heat radiation of longitudinal rib shape, and the heat radiation of longitudinal rib shape is positioned at the place that the car light body is suitable for dispelling the heat.Heat pipe is the middle hollow tubular body that is, is vacuum in the tubular body, and wick is arranged on its inwall, and working solution is arranged in the wick.The utility model has the advantages that: test shows that this radiating subassembly is installed on the Rear Fog Lamp of Passat concept car, and device temperature can be reduced to below 80% of initial value.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is a heat pipe structure generalized section of the present utility model,
Embodiment
The heat pipe type radiating subassembly is made up of heat sink 1, heat pipe 2 and longitudinal rib shape heat radiation 3 among the figure, heat sink 1 is a heat conduction block, one end of heat pipe 2 is connected with heat sink 1, and the other end of heat pipe 2 connects longitudinal rib shape heat radiation 3, and longitudinal rib shape heat radiation 3 is positioned at the place that the car light body is suitable for dispelling the heat.Heat pipe 2 is the middle hollow tubular body that is, is vacuum in the tubular body, and wick 4 is arranged on its inwall 3, and working solution 5 is arranged in the wick 4.Heat sink 1 connects pyrotoxin (light-emitting diode component plate), its heat transferred of distributing is received, pass to heat pipe 2 then, trend according to the structures shape heat pipe 2 of luminous intensity distribution plate and lamp mounting bracket, the effect of heat pipe 2 is from heat sink position heat to be delivered to the place that is suitable for dispelling the heat in the car light body efficiently, because heat pipe 2 absorbs heat its wick 4 vaporizations at heat sink 1 place of contact, its steam flow cold junction condenses, and is entered the hot junction from cold junction by wick 4 is capillary pumped then.Its form and size will be determined according to the needs of heat dissipation capacity and Vehicle lamp structure, the effect of fin mainly is the heat with heat pipe transmission, by the mode of free convection, is delivered in the environment of car light and goes, in conjunction with the design feature of car light, adopt longitudinal rib shape fin 3.
Claims (2)
1, the heat pipe type radiating subassembly used of light-emitting diode (LED) car lamp, it is characterized in that: the heat pipe type radiating subassembly is by heat sink, heat pipe, form with rib shape fin, heat sink is a heat conduction block, one end of heat pipe is connected with heat sink, and the other end of heat pipe connects the heat radiation of longitudinal rib shape, and fin is positioned at the place that the car light body is suitable for dispelling the heat.
2, the heat pipe type radiating subassembly of using by the described light-emitting diode (LED) car lamp of claim 1 is characterized in that: heat pipe is hollow tubular body for the centre, is vacuum in the tubular body, and wick is arranged on its inwall, and working solution is arranged in the wick.
