Description
Technical field
The present invention relates to a kind of TV set heat radiator, especially a kind of heat abstractor of liquid crystal TV set.
Background technology
Television set operationally mainboard can produce amount of heat, and this just needs to carry out reinforcement heat radiation to mainboard, and a normal operation maintaining television set, keeps its operation stability; Two protect television set, extend the useful life of television set.Existing LCD TV mainboard helps mainboard heat radiation by fixing aluminium heat sink, and fin is fixed to mainboard side with viscose glue, but aluminium heat sink is traditional radiating mode, and heat conduction neither be good especially, especially summer.Also having a kind of is use fan forced heat radiation, but this radiating mode noise ratio is comparatively large, and electric fan runs power consumption, and electric fan is also short for useful life in addition, has gone bad and will change, because this increasing extra operating cost.Also have one to be utilize ceramic radiating fin to dispel the heat, ceramic radiating fin not only conductive coefficient is low but also easily ftracture, if make radiator, must reticulate, but ceramic hardness is high, intensity is low, and be easy to break up, manufacturing cost is high.
Summary of the invention
The object of this invention is to provide a kind of heat pipe that utilizes and carry out the TV set heat radiator dispelled the heat, the heat that TV SKD produces is derived housing of TV set by heat pipe.
To achieve these goals, the present invention includes available liquid crystal TV SKD (1), ladder radiating block (3), strip radiating block (9) and heat pipe, wherein ladder radiating block (3) is fixed on the side of TV SKD (1), strip radiating block (9) is located at television cabin (10) inner side, heat pipe is provided with between ladder radiating block (3) and strip radiating block (9), ladder radiating block (3) is fixed on mainboard (1) by screw (2), strip radiating block (9) is fixed by screw (12) and casing (10), ladder radiating block (3) is in notch cuttype, and be an entirety, material is aluminium, each cascaded surface is all provided with the shrinkage pool of a diameter 1.1cm, strip radiating block (9) is in bar shaped, and material is aluminium, and the shrinkage pool position on corresponding ladder radiating block (3) is provided with the shrinkage pool of three diameter 1.1cm, heat pipe is straight tube, and be divided into evaporation section (4), adiabatic section (6) and condensation segment (7), have screw thread outside heating pipe, tubing is aluminium, vacuumizes in pipe, and caliber is no more than 1cm, and working media is ammonia, relies on gravity reflux, evaporation section (4) is located in the shrinkage pool in ladder radiating block (3), condensation segment (7) is located in the shrinkage pool in strip radiating block (9), gap between shrinkage pool in evaporation section (4) and ladder radiating block (3) is filled with high thermal conductive silicon film (5), and the gap between the shrinkage pool in condensation segment (7) and strip radiating block (9) is filled with high thermal conductive silicon film (8), casing (10) is provided with louvre (11), strengthens heat radiation.
Compared with existing TV set heat radiator, TV set heat radiator good heat dissipation effect of the present invention, does not need extra operating cost, noiselessness and long service life, and heat pipe employing is that working medium relies on the straight tube of gravity circulation to be not the heat pipe arranging liquid-sucking core in pipe, therefore price is also low.
Accompanying drawing explanation
Fig. 1 is the structural principle schematic diagram of TV set heat radiator of the present invention.
Number in the figure: 1. mainboard; 2. screw; 3. ladder radiating block; 4. evaporation section; 5. high thermal conductive silicon film; 6. adiabatic section; 7. condensation segment; 8. high thermal conductive silicon film; 9. strip radiating block; 10. casing; 11. louvres; 12. screws.
Embodiment
TV SKD (1) is connected by screw (2) with ladder heat-conducting block (3), the television set heat that mainboard (1) produces in running passes to ladder radiating block (3), three cascaded surfaces of ladder radiating block (3) are respectively provided with the shrinkage pool that is installed heat pipe, diameter is 1.1cm, three heat pipe evaporator sections (4) are inserted in the shrinkage pool of ladder radiating block (3), high thermal conductive silicon film (5) is had between evaporation section (4) and ladder radiating block (3), be used for filling the gap between evaporation section (4) and ladder radiating block (3) shrinkage pool, improve heat transfer efficiency, because the conductive coefficient of high thermal conductive silicon film can reach 5.0W/mK, and air conduction coefficient only has 0.03W/mK.The heat of ladder heat-conducting block (3) passes to the shell of evaporation section (4), the heat of shell passes to inner casing through heat conduction, again heat is passed to the liquefied ammonia working medium in evaporation section (4), liquefied ammonia absorbs latent heat of vaporization evaporation, and the ammonia vapour of evaporation takes heat to condensation segment (7) through the adiabatic section (6) of heat pipe.Heat pipe condenser section (7) inserts in three shrinkage pools of the correspondence distribution in strip radiating block (9), bore dia is 1.1cm, there is high thermal conductive silicon film (8) between condensation segment (7) and bar shaped radiating block (9), be used for the gap of filling between the two.After liquefied ammonia in heat pipe condenser section (7) runs into colder condensation segment (7) interior shell, the releasing latent heat of vaporization is condensed, liquefied ammonia working medium has transferred heat to the inner casing of condensation segment (7), inner casing transfers heat to shell again, condensation segment (7) shell transfers heat to radiating block (9), liquefied ammonia in heat pipe condenser section (7) after condensation under gravity, to fall back evaporation section (4) again through adiabatic section (6).Strip radiating block (9) is connected by screw (12) with casing (10), casing distributes louvre (11), and the louvre of heat on casing and casing (11) on radiating block (9) is diffused in air.
When heat pipe evaporator section (4) is very little with the temperature difference of condensation segment (7), when the general temperature difference is 0.1 DEG C, the heat pipe evaporator section liquid ammonia absorption latent heat of vaporization flashes to gas, under differential pressure action, ammonia steam rises to condensation segment (7) along pipe internal cavity, contact with colder radiating block (9), release the latent heat of vaporization, be condensed into liquid again, under gravity, liquid ammonia flows back to evaporation section (4) along tube wall and to absorb heat evaporation again, circulate and so forth, take the heat on mainboard out of casing.
