Description
Technical field
The present invention relates to a kind of heat abstractor, be specifically related to a kind of heat abstractor for LED.
Background technology
LED is a kind of can be the semiconductor of visible ray by electric energy conversion, its energy consumption be only the 1/l0 of incandescent lamp, common energy-saving lamp 1/4oLED lamp except the advantage with environmental protection and energy saving, also there is the plurality of advantages such as the life-span is long, light efficiency is high, radiationless.Therefore, the upgraded product that LED throws light on as the next generation is the new industry with great potential.
The application of LED is subject to the puzzlement of heat dissipation problem always, heat dissipation problem badly influences light efficiency and the life-span of LED light source, the heat radiation of LED generally will rely on radiator, traditional radiator is all generally closed cylindrical shape, outside can distribute some fins, although reach basic heat radiation object, but radiator close make radiator inner air cannot in time with extraneous air circulation, just cause radiating efficiency low, cause LED light source and power source temperature too high, thus had influence on light efficiency and the life-span of LED, and in order to make radiator effect become better, existing radiator also can offer louvre on outer wall, it is too large that louvre designs, radiator has not had again the effect of dust and moisture, but louvre design is too little, though serve to the effect of LED dust and moisture, but what the heat that LED produces still cannot be unobstructed distributes, and louvre is too little, time one is long, being easy to can by dust shutoff, louvre is caused not reach the object of heat radiation, this also certainly will have influence on the service life of LED.
Summary of the invention
The invention is intended to provide a kind of good heat dissipation effect, again can the heat abstractor for LED of dust and moisture.
The heat abstractor for LED in this programme, comprise heat dissipating housing, cavity is provided with in heat dissipating housing, cavity bottom is connected with water inlet pipe, cavity top is connected with outlet pipe, cooler bin is connected with between water inlet pipe and outlet pipe, water inlet pipe is provided with cavity, the first tooth bar being closed in water inlet pipe is provided with in cavity, water pump is provided with between cavity and cooler bin, the surface of heat dissipating housing has groove, , horizontal connecting rod is slidably connected in groove, expander is provided with between groove bottom wall and connecting rod, first tooth bar and the second tooth bar are engaged with same gear jointly, second tooth bar is connected with the fixing elastic component in one end, the switch controlling water pump is provided with between second tooth bar and elastic component.
The know-why of this programme and beneficial effect are: when lamp is not opened, and the temperature of lamp is room temperature, and expander can not dilatancy, and the second tooth bar can not move.
When needing to use lamp, opened by lamp, the temperature of lamp constantly raises; When temperature is not high, expander still can not dilatancy, and the second tooth bar still can not move, and heat dissipating housing just can ensure the heat radiation of lamp.
When temperature continues to continue to raise, when temperature becomes very high, expander will be subject to the impact distortion of temperature, driving second tooth bar moves to the direction away from expander by expander, elastic component will be compressed, and driven gear rotates by the second tooth bar, and drive first tooth bar moves downward by gear, top from cavity is slipped to cavity bottom by the first tooth bar, water inlet pipe will with cavity connects, the temperature of lamp continues to raise, expander continues dilatancy, expander will drive the second tooth bar motion further, second tooth bar will touch switch, water pump will be opened, water pump is extracted out the cooling water in cooler bin, be pumped in cavity through cavity, cooling water will flow in cavity, the heat that cooling water will absorb in heat dissipating housing, flow in the outlet pipe on cavity top always, in the process flowed in heat dissipating housing, the temperature of cooling water will be enhanced, and flow into cooler bin from outlet pipe, cooling water is drawn into again in water pump from cooler bin afterwards, cooling water is pumped in cavity again by water pump, circulation like this, in the flow process of water, heat is taken away by water in heat dissipating housing, and specific heat of water holds comparatively large, and heat can be taken away by the water of flowing compared with air quickly, thus improves radiating effect.
When lamp is closed, the constant temperature of lamp reduces, expander is by reinstatement, second tooth bar will be separated with switch, and water pump shuts down, and driven gear also rotates by the second tooth bar, gear also drives the first tooth bar to reset, first tooth bar will be closed water inlet pipe, the heat of the surplus between heat dissipating housing and lamp, by with the water heat exchange be deposited in cavity; Because whole heat radiation inner cover is closed, lamp can not contact with air all the time, and the dust in air can not contact with lamp with steam, serves the effect of dust and moisture.
Further, expander is block rubber, and block rubber can expanded by heating, after temperature is reduced to normal temperature, returns to original state again, can play the effect of driving second tooth bar.
Further, expander and the second tooth bar are fixed together by connector, and this is arranged, and expander and the second tooth bar can be made to be structure as a whole, and when expander resets, the second tooth bar can be driven to reset, thus accelerate the reset of the second tooth bar.
Further, elastic component is spring, and spring is a kind of machine components utilizing elasticity to carry out work, there is deformation under external force with the part that elastomeric material is made, restore to the original state again after removing external force, be connected to the spring on the second tooth bar, when expander reinstatement, the second tooth bar can be promoted and resets.
Further, switch is touch switch, facilitates the control to water pump.
