Description
Technical field
This utility model relates to a kind of heat abstractor, has been specifically related to a kind of heat abstractor for LED。
Background technology
LED is a kind of quasiconductor that can convert electrical energy into visible ray, its energy consumption be only the 1/l0 of electric filament 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 life-span length, light efficiency be high, radiationless。Therefore, the upgraded product that LED illuminates as the next generation, is the new industry with great potential。
The application of LED is constantly subjected to the puzzlement of heat dissipation problem, heat dissipation problem badly influences light efficiency and the life-span of LED light source, the heat radiation of LED generally to rely on radiator, traditional radiator is typically all the cylindrical shape of closing, outside can be distributed some fins, although having reached basic heat radiation purpose, but radiator is closed and is made radiator inner air to circulate with extraneous air in time, just cause radiating efficiency low, cause that LED light source and power source temperature are too high, thus having 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 the outer wall, it is too big that louvre designs, radiator has not had again the effect of dust and moisture, but louvre design is too little, though serving 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, it is easy to be blocked by dust, cause that louvre does not reach the purpose of heat radiation, this also certainly will have influence on the service life of LED。
Utility model content
This utility model be 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, including heat dissipating housing, cavity it is provided with in heat dissipating housing, cavity bottom is connected to water inlet pipe, cavity top is connected to outlet pipe, cooler bin it is connected between water inlet pipe and outlet pipe, water inlet pipe is provided with cavity, the first tooth bar being closed in water inlet pipe it is provided with in cavity, water pump it 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 it 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 to the elastic component that one end is fixing, the switch controlling water pump it is provided with between second tooth bar and elastic component。
The know-why of this programme and have the beneficial effect that when lamp is not turned on, the temperature of lamp is room temperature, expander will not dilatancy, the second tooth bar will not move。
When needing to use lamp, being opened by lamp, the temperature of lamp constantly raises；When temperature is not high, expander still will not dilatancy, the second tooth bar still will not move, and heat dissipating housing ensures that the heat radiation of lamp。
When temperature continues for raising, when temperature becomes significantly high, expander is subjected to the impact deformation of temperature, expander moves driving the second tooth bar to the direction away from expander, elastic component will be compressed, and driven gear is rotated by the second tooth bar, and gear moves downward driving the first tooth bar, first tooth bar will be slipped to cavity bottom from the top of cavity, and water inlet pipe will connect with cavity；The temperature of lamp continues to raise, expander continues dilatancy, expander will drive the second tooth bar motion further, touching is switched by the second tooth bar, water pump will be opened, water pump will be extracted the cooling water in cooler bin out, it is pumped in cavity through cavity, cooling water will flow in cavity, the heat that cooling water will absorb in heat dissipating housing, it flow in the outlet pipe on cavity top always, in heat dissipating housing in the process of flowing, the temperature of cooling water will be enhanced, and it is flowed into cooler bin from outlet pipe, cooling water is drawn into again in water pump from cooler bin afterwards, cooling water pump is entered in cavity again by water pump, so circulation；In the flow process of water, heat is taken away by water in heat dissipating housing, and specific heat of water holds relatively big, and heat can be taken away by the water of flowing quickly compared with air, thus improve radiating effect。
When lamp is closed, the constant temperature of lamp reduces, expander is by reinstatement, second tooth bar will separate with switch, and water pump shuts down, and driven gear is also rotated 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 being deposited in cavity；Owing to whole heat radiation inner cover is to close, lamp all the time will not with air contact, and the dust in air will not contact with lamp with steam, serves the effect of dust and moisture。
Further, expander is block rubber, block rubber can expanded by heating, after temperature is reduced to room temperature, return to again original state, can play drive the second tooth bar effect。
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 accelerating 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, the part made with elastomeric material deforms upon under external force, restores to the original state again, be connected to the spring on the second tooth bar after removing external force, when expander reinstatement, the second tooth bar can be promoted to reset。
Further, switch as touch switch, facilitate the control to water pump。
