Description
Technical field
The present invention relates to a kind of radiator, and in particular to a kind of device for LED light heat dissipation.
Background technology
LED is a kind of semiconductor that can convert electrical energy into visible light, and energy consumption is only the 1/l0 of incandescent lamp, common section
The 1/4o LED light of energy lamp also has many advantages, such as long lifespan, light efficiency are high, radiationless in addition to having the advantages that environmental protection and energy saving.
Therefore, upgraded products of the LED as next generation's illumination, is the new industry with great potential.
The application of LED is constantly subjected to the puzzlement of heat dissipation problem, and heat dissipation problem seriously affects light efficiency and the longevity of LED light source
The heat dissipation of life, LED light will generally rely on radiator, and traditional radiator is typically all closed cylindrical shape, and outside can be distributed one
A little fins, although having reached basic heat dissipation purpose, radiator close so that radiator inner air can not in time with outside
The air circulation on boundary just causes radiating efficiency low, causes LED light source and power source temperature excessively high, to influence the light efficiency of LED
And the service life, and in order to make radiator effect become more preferable, existing radiator can also open up heat emission hole on the outer wall, and heat emission hole is set
That counts is too big, and radiator has not had the effect of dust and moisture again, and heat emission hole designs too small, though it plays to LED light
The effect of dust and moisture, but what the heat of LED light generation still can not be unobstructed distributes, and also heat emission hole is too small, the time
One length, it is easy to can be blocked by dust, cause heat emission hole that the purpose of heat dissipation is not achieved, this certainly will also influence the use of LED light
Service life.
Invention content
The invention is intended to a kind of good heat dissipation effect is provided and can dust and moisture the device for LED light heat dissipation.
The device for LED light heat dissipation in this programme, including heat dissipating housing, heat dissipating housing include heat dissipation outer cover and are located at heat dissipation
Heat dissipation inner cover in outer cover, heat dissipation outer cover are equipped with inlet and outlet, radiate and are equipped with expansion between outer cover and heat dissipation inner cover
The side of body, expander mutually has equipped with the first fixed cylinder, and the expander other side is equipped with link block, and link block includes being located at connection
Block in the middle part of block, block close water outlet, and block is equipped with the outlet of cooperation water outlet close to the side of expander, and block is remote
Side from expander is equipped with the import of cooperation water inlet, and water inlet is closed, is connected between import and heat dissipating housing by inlet wall
Elastic component.
It the technical principle of this programme and has the beneficial effect that：When lamp is not turned on, the temperature of lamp is room temperature, and expander will not be swollen
Bulging deformation, link block still close inlet and outlet.
When needing using lamp, lamp is opened, the temperature of lamp constantly increases；When temperature is not high, expander still will not be swollen
Bulging deformation, link block still close inlet and outlet, and heat dissipating housing ensures that the heat dissipation of lamp.
When temperature continues for increasing, when temperature becomes very high, expander is by deformation affected by temperature, expander one
Side is fixed by the first fixed block, and the expander other side is moved block is drivingly connected to far from the direction of expander, and elastic component will be by
It compresses, the inlet and outlet on link block is communicated with inlet and outlet respectively, and the water with certain pressure will pass through water inlet
Mouth enters between heat dissipation outer cover and heat dissipation inner cover, who will be flowed between heat dissipation outer cover and heat dissipation inner cover, always the company of flowing to
Connect the outlet of block, and be flowed into water outlet by outlet, from water outlet flow out, in the flow process of water, water by heat from
It is taken away in heat dissipating housing, the specific heat capacity of water is larger, and flowing water can quickly take away heat compared with air, scattered to improve
Thermal effect.
When closing lamp, the constant temperature of lamp reduces, and expander will restore to the original state, inlet and outlet will respectively by
Inlet wall and block closing, water will not flow, and the heat between heat dissipating housing and lamp will exchange heat with water；Due to the inner cover that entirely radiates
It is closed, lamp will not be contacted with cold air, and heat dissipation inner cover plays the role of to lamp dust and moisture.
Further, expander is rubber block.Rubber block can expanded by heating, after temperature is reduced to room temperature, and be restored to original state
It can play the role of being drivingly connected block and conducting block.
Further, inlet and outlet setting can make water be more easy to be flowed into outside heat dissipation in heat dissipation cover upper, this setting
The bottom of cover accelerates the flowing of water.
Further, elastic component is spring, spring be it is a kind of using elasticity come the machine components of work, be made of elastic material
Part deform upon under external force, restore to the original state again after removing external force, the spring being connected on link block can expand
When body restores to the original state, connection block reset is pushed.
Further, it radiates and is fixedly provided with the second fixed cylinder, elastic component and the second fixed cylinder phase between outer cover and heat dissipation inner cover
Even, the second fixed cylinder can elastic component be easily fixed, reduce the difficulty that elastic component is connected and fixed.
