Description
Technical field
The utility model is related to heat abstractor technical fields, more particularly to a kind of for the accurate of liquid crystal projection apparatus
Radiator.
Background technology
Projecting apparatus is a kind of equipment that can be projected image or video on curtain, can be same by different interfaces
Computer, VCD, DVD, BD, game machine, DV etc., which are connected, plays corresponding vision signal.LCD liquid crystal projection apparatus is projecting apparatus
A type, have the advantages that at low cost, stability is good, volume is moderate, be readily produced, be currently low price entry level projection
The main product of instrument in the market.
Phenomena such as will appear failure since projecting apparatus liquid crystal display temperature is excessively high, blacking, so the heat dissipation for solving liquid crystal display is asked
It has inscribed into the most important thing.Traditional radiating mode is reached by introducing a large amount of cold airs from projecting apparatus liquid crystal display bottom or side
To the purpose of heat dissipation.The shortcomings that this method is：Although the radiating airflow speed of flowing is quickly, since flow direction is parallel
In liquid crystal display, so close to the side of liquid crystal display, low speed adhesive layer can be formed.Since air velocity is low, so that rate of heat exchange
It is very low.If conventional projector is wanted to improve the heat-sinking capability of liquid crystal display, it is necessary to which the drawbacks of increasing air quantity and wind speed, thus bringing be
Noise is big, and energy consumption is big and dust is more.
How above-mentioned technical problem striving direction at those skilled in the art is solved.
Utility model content
The purpose of this utility model is that：In order to solve traditional liquid crystal screen cooling mechanism heat dissipation effect difference and heat exchanger effectiveness
Very low problem, the utility model provide a kind of accurate radiator for liquid crystal projection apparatus.
The utility model specifically uses following technical scheme to achieve the goals above：
A kind of accurate radiator for liquid crystal projection apparatus, including sequentially connected fan component, air duct and storage bellows,
Be provided with multigroup nozzle on storage bellows, be provided with adjuster on every group of nozzle, nozzle is corresponded with adjuster, each nozzle with
Adjuster is directed toward the different zones on the surface for the liquid crystal display for needing to radiate, and temperature sensor is respectively arranged in liquid crystal display and air duct
A and temperature sensor B.
Further, the fan component uses windy fan structure, including fan drum, turn in fan drum
Axis, shaft are equipped with flabellum, and fan drum rear portion is connected with babinet, and shaft one end is stretched into babinet and electric with the driving in babinet
Machine connects, and is provided with temperature sensing device and power supply in babinet, power supply is electrically connected with driving motor, temperature sensor.
Further, babinet is embedded into shell by the form of buckle, and flabellum is dismountable flabellum.More flabellum arrangement sides
Formula can be that parallel connection can also be concatenated mode.According to the design logic of the present apparatus, in the case of being based on series connection overlap mode,
Wind speed can be reduced and improve wind pressure, had higher efficiency.
Further, the air-out direction of the exhaust outlet of the storage bellows and air duct axis angle are 0 ° to 90 °, are taken
Certainly in the relative position of liquid crystal display and air duct.According to practical application, basic logic is the distinguished and admirable light-receiving surface for blowing to liquid crystal display.
Further, the shapes and sizes of nozzle can be adjusted, to by different in flow rate and flow air-flow, blow
To the different zones of liquid crystal display, to which more the different feature of liquid crystal display different zones cooling requirements, realization are accurately efficient
Heat dissipation.
Further, the temperature difference of two groups of temperature sensors can provide more suitably radiating mode for device, can be with
The rotating speed and nozzle control governor gear of fan are adjusted accordingly.
Further, the material of bellows is stored up, can be the higher metal material of heat transfer efficiency or other materials, be conducive to
The temperature for improving radiating airflow, to improve heat dissipation effect.
The beneficial effects of the utility model are as follows：
1. the maximum value of the utility model is by traditional single parallel big air port, having made multigroup inclination into has certain finger
To nozzle, so as to which air-flow to be accurately directed to the specific region or even each region of liquid crystal display.Every group of nozzle export
Air-flow corresponding liquid crystal display region can be directly blowed to proper speed, therefore, the temperature difference is big, flow velocity is high, pressure
Greatly, to which radiating efficiency is very high.Under traditional single air outlet heat dissipation logic, there are low speed flow attachments for entire heat dissipation region
Layer can cause side gas flow temperature high moreover, air-flow flows to the other side from side, and other side gas flow temperature is low, liquid crystal display heat dissipation
It is uneven.Therefore the utility model is the great innovation for liquid crystal display heat dissipation theory and practice.
2. since it is directed toward the different zones of liquid crystal display, from top to bottom or from left to right, to liquid crystal from nozzle
The distance of screen surfaces is different, and the temperature of liquid crystal screen surfaces is also due to the speciality of projector is different.So multigroup nozzle
It can be arranged to different shapes and sizes according to aerodynamic principle, to obtain different wind speed and air quantity, blow to spy
Fixed liquid crystal display region, to achieve the purpose that precisely to radiate.To which cold air utilization rate is high, loss is reduced, noise is reduced,
The effect of heat dissipation is greatly improved, the service life of complete machine also can be accordingly improved.Also dust-proof pressure and fan are reduced simultaneously
Noise.
3. windy fan structure enables fan according to required air quantity, decision is to carry out in parallel or in series, it might even be possible to
Decision has several groups of fan works.According to temperature difference situation, multimachine, which starts, improves efficiency or single machine startup, reduces energy consumption.Root
According to aerodynamic principle, for example, it is concatenated in the case of, so that it may further to compress air, improve pressure.To be conducive to
Cut-out governing air-flow.
4. due to the design of buckle so that fan is easy to disassemble, is convenient to clean fan internal dust, to extend using the longevity
Life, dismountable flabellum are conveniently replaceable the flabellum of aging.
5. due to the setting of multiple temperature sensors, according to the gas flow temperature after the gas flow temperature in bellows, and heat dissipation, just
It can learn the efficiency of heat dissipation and speculate the temperature of liquid crystal display, the settings such as rotating speed to control fan precisely dissipate to realize
The purpose of heat.
6. according to the illumination of projector and image-forming principle, exhaust outlet enters the wind position angulation with storage bellows, according to production
The concrete structure of product can be acute angle, can also be obtuse angle.But basic principle is all that air-flow is blowed to the light-receiving surface of liquid crystal display.
