Description of drawings
Fig. 1 is the schematic diagram of the radiator structure of the liquid crystal TV set that provides of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, the radiator structure of a kind of liquid crystal TV set that the utility model embodiment provides, comprise radiator 1, wiring board 2 and be fixedly mounted on power component 3 on the described wiring board 2, also comprise a minimum heat pipe 4, described heat pipe 4 comprises evaporation ends 41 and condensation end 42, described evaporation ends 41 is fixedlyed connected with described power component 3, and described condensation end 42 is fixedlyed connected with described radiator 1.By such design, the heat that is produced in the time of can making power component 3 work can in time conduct to described evaporation ends 41, and the heat of described condensation end 42 can in time conduct to radiator 1 and dispel the heat.
Particularly, described heat pipe 4 closed at both ends also form a closed cavity in inside, are provided with liquid in the described closed cavity.Described closed cavity sidewall is installed with some capillaries that make described liquid be flow to evaporation ends 41 by described condensation end 42.When the heat that is produced when power component 3 work conducts to the evaporation ends 41 of fixedlying connected with power component 3, Liquid Absorption heat in the described evaporation ends 41, simultaneous temperature rises, thereby make power component 3 obtain cooling, after the heat that is produced when the liquid in the described evaporation ends 41 is worked by power component 3 is heated to boiling point, liquid evaporation in the described evaporation ends 41 forms steam, described steam flows and discharges heat at the lower condensation end 42 of relative temperature to condensation end 42, is condensed into liquid simultaneously.Described condensation end 42 conducts to the radiator 1 of fixedlying connected with condensation end 42 with the heat that steam discharged and dispels the heat.Described steam is back to evaporation ends 41 at the liquid of condensation end 42 condensations institute shape under gravity or capillary force.Absorb heat, evaporate in the evaporation ends 41 of heat pipe 4 by liquid, in condensation end 42, carry out the circulation of heat release, condensation, the heat that is produced when making power component 3 work can constantly conduct in the radiator 1 by heat pipe 4, radiator 1 again the type of cooling by radiation and free convection with heat delivered to environment, thereby make power component 3 keep reliable working temperature, be beneficial to reliability that improves liquid crystal TV set work and the life-span that prolongs liquid crystal TV set.
More specifically, described closed cavity is a vacuum cavity, be beneficial to the boiling point that reduces liquid in the described heat pipe 4, the boiling point that makes described liquid is near ambient temperature, thereby temperature rises to boiling point as early as possible and forms steam be beneficial to the heat that the liquid in the described heat pipe 4 are produced when 3 work of absorbed power element after, steam flow discharges heat and is condensed into liquid to condensation end 42, the heat that is produced when making power component 3 work can conduct in the radiator 1 as early as possible by heat pipe 4, has avoided heat to pile up at power component 3 places.
Further, the fin 11 that described radiator 1 is piled up by some intervals is formed, be beneficial to increase the area of dissipation of radiator 1, improve the heat dispersion of radiator 1, heat can be conducted in each fin 11 equably, thereby the heat in the radiator 1 can be transferred in the environment by fin 11 as soon as possible, the temperature of condensation end 42 is reduced, thereby be beneficial to the vapour condensation in the condensation end 42.Described fin 11 offers the through hole that can wear for condensation end 42, is beneficial to condensation end 42 and fixedlys connected with radiator 1 reliably, thereby steam discharged in the condensation end 42 heat is conducted in each fin 11 in the radiator 1 reliably.
Particularly, described radiator 1 is fixed at liquid crystal TV set ventilation for enclosures window place.Be that specifically described heat pipe 4 can bend, the heat that is produced in the time of power component 3 can being worked like this causes suitable position neatly and dispels the heat, thereby make the layout of radiator 1 flexible, the radiator structure of the liquid crystal TV set that the utility model provides is fixed at liquid crystal TV set ventilation for enclosures window place with described radiator 1, the heat that is beneficial in the described radiator 1 transfers in the environment quickly, thereby the element that makes liquid crystal TV set inside keeps reliable working temperature, thereby is beneficial to the working life that prolongs liquid crystal TV set.
