Embodiment
The utility model provides a kind of cooling system of laser television, for making the purpose of this utility model, technical scheme and effect clearly, clearly, further describes the utility model referring to the accompanying drawing embodiment that develops simultaneously.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1 and Fig. 2, it is respectively part-structure schematic diagram and the structured flowchart of the cooling system of the laser television that the utility model embodiment provides.As shown in the figure, the cooling system of laser television of the present utility model comprises radiator fan group 10, the sets of temperature sensors 20 for collecting temperature data and the control device 30 for the rotating speed that controls radiator fan group 10 according to temperature data, and described sets of temperature sensors 20 connects radiator fan group 10 by control device 30.Particularly, temperature sensor, be connected transmit the signal of telecommunication by wire 301 between radiator fan group 10 with control device 30.
The cooling system of the laser television that the utility model provides, by sets of temperature sensors 20 collecting temperature data, controlled the rotating speed of radiator fan group 10 according to temperature data by control device 30, achieve the performance of " temperature is high; wind-force is large, and temperature is low, and wind-force is weak ", achieve namely energy-conservation, again reduce the noise of noise cooling system.
Please continue to refer to Fig. 1, the cooling system of laser television of the present utility model, it is characterized in that, also comprise some radiating tubes 40 and fin 50, one end of described radiating tube 40 is fixed on the laser 60 of laser television, the Part I of described radiating tube 40 is coiled in fin 50, and described fin 50 is positioned at the both sides of laser 60, and the heat that laser 60 is distributed sheds in time.
Described radiating tube 40 is heat dissipation copper pipe, is injected with cooling fluid in it, and vacuumizes in pipe before injection cooling fluid.Wherein, described in part heat sink 50, radiator fan group 10 is positioned at the side of fin 50, near radiator fan group 10, can be reduced the temperature of cooling fluid by radiator fan group 10 blowing.Its operation principle is: cooling fluid under vacuum conditions boiling point is very low, if the temperature of laser 60 raises, cooling fluid will be evaporated the other end of the torrid zone to heat dissipation copper pipe, after cooling fluid to the other end or other parts of heat dissipation copper pipe, because the effect of fin 50 and fan, cooling fluid can be cooled to liquid, then flows back to.So repeatedly, heat is just constantly mobile, makes the principle of air conditioner, if circulation cooling, thus can quickly by heat conduction to fin 50 and fan, heat is discharged outside laser television main body fast.
The Part II of described radiating tube 40 is coiled in the below (Part II as radiating tube 40 can be positioned on the bottom surface of laser 60) of laser 60, directly can reduce the heating temp of laser 60, improve radiating effect further.
Preferably, the Part III of described radiating tube 40 coils at least one side of laser 60, as the surrounding etc. being positioned at the downside of radiating tube 40, the left and right sides or coil in laser 60, specifically can arrange according to the design space of cooling system, the setting of fin 50 also can be arranged according to the design space of cooling system, the place that radiating tube can cover fin can arrange fin, and for the place of narrow space, radiating tube can suitably expose.
Please continue to refer to Fig. 2, described sets of temperature sensors 20 comprises laser temperature sensor 201, colour wheel temperature sensor 202 and environment temperature sensor 203, be respectively used to the temperature of testing laser device 60, colour wheel temperature and ambient temperature, described radiator fan group 10 is corresponding to be comprised: laser fan 101, colour wheel fan 102 and environment warm air fan 103.Described control device 30 can adopt the control chip of MSB918 to control, realize the process of data and the control of rotating speed, certainly also can adopt the MCU chip of other model or be controlled by the mode that chip and independent rotational speed governor combine, the utility model is not restricted this.
In order to improve the intelligence degree of the cooling system of laser television of the present utility model, the rotating speed of described radiator fan group 10 is divided into five grades, specifically the gear of radiator fan and the minimum temperature (as 45 DEG C) of radiator fan startup are set by control device 30, not starting radiator fan when not needing heat radiation, saving electric energy.
Concrete, the gear of fan can be set to 5 from height to low, temperature often reduce by 2 DEG C then electric fan wind speed automatically to decline a gear; Temperature often raises 2 DEG C, then the wind speed of radiator fan rises a gear automatically.If setting electric fan minimum operating temperature is 45 DEG C, when lower than this temperature, the automatic stall of radiator fan, when temperature is higher than 45 DEG C, radiator fan will restart again.And each transducer and fan work independently, corresponding respective temperature controls, and avoids too much Redundancy Design, achieves energy-conservation.
In sum, the utility model carries out data acquisition by temperature sensor to each key point temperature and sets up a cooling control system, makes radiator fan variation with temperature and auto-changing gear, realize the performance of " temperature is high; wind-force is large, and temperature is low, and wind-force is weak ".And can arrange the minimum operating temperature of radiator fan, when temperature is lower than set temperature, fan will cut out automatically; When just starting higher than fan during this temperature, namely achieving energy-conservation, again reducing the noise of noise cooling system.
Meanwhile, each transducer and fan work independently, and corresponding respective temperature controls, and avoids too much Redundancy Design, achieves energy-conservation, and just start fan when needs fan work, turn avoid the noise that all fans work simultaneously, achieve noise reduction.
In addition, the utility model, in conjunction with the radiating mode of heat dissipation copper pipe radiation fin, adds cooling fluid inside heat dissipation copper pipe, is realized the transmission of heat by fluid conditions conversion, adopts various ways to dispel the heat simultaneously, improves the heat dispersion of cooling system.
Be understandable that; for those of ordinary skills; can be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, and all these change or replace the protection range that all should belong to the claim appended by the utility model.
