Description
Technical field
The present invention is relevant for a kind of cooling control method and device, more particularly relevant for a kind of can be according to the operating position of a system and flexibly adjust cooling control method and the device of heat radiation time.
Background technology
Along with the mode of meeting becomes more diverse, the consumer also improves relatively for the requirement of projector equipment.Therefore, projector becomes key element indispensable in the meeting.Since liquid crystal projector was asked the city, each manufacturer of tame projector was devoted to improve the projection brightness of projector invariably, can present perfect bulletin under normal indoor light in the hope of making projector.Projector wants and can make bulletin not needing to turn off the light, draw under the normal indoor light of curtain, must the accent light effect.Therefore, employed bulb wattage is just constantly upwards soaring.In this case, need a kind of have quick heat radiating and the good light fixture of radiating effect, if can't handle heat dissipation problem perfectly, the device of projector inside may be seriously influenced.
About the radiating mode of projector, below will be divided into when opening projector according to the time that projector uses, three time point discussion such as when using projector, when closing projector.
Radiating mode when at first, using projector is to keep projector's temperature inside in certain safe range.
Then, radiating mode explanation that will be when closing projector.After projector used a period of time, projector inside and lamp were all still kept high temperature.So, on the heat dissipation design when shutdown, can make the heat abstractor of projector inside, as fan, one period set time of continuous running, after dropping to the uniform temperature value, wait closes again, to guarantee that heat radiation is fully.And the decision of this set time is normally learnt according to experiment value.
In general, if the normal projector that uses, heat abstractor should make projector fully dispel the heat when power cutoff.Yet, but always must allow the user wait for so one period set time, the power supply of projector could be turn-offed fully, quite lose time.In addition, when projector closes, generally the fan of projector inside can be set at maximum (top) speed and dispel the heat.Yet, if shortening heat radiation time and promote rotation speed of the fan, the noise that it produced will make the user feel uncomfortable.In addition, along with the variation of environment, also may differ because of using the residing environment temperature of projector, for example ambient temperature is higher or low excessively, causes the deficiency of time of heat radiation or too much, lamp or the device of projector inside is caused the infringement of permanent and continuation.That is to say that preferably in the environment, this radiating mode will be wasted user's stand-by period at radiating condition.And under the relatively poor environment of radiating condition, for example in the environment of unfavorable heat radiation or projector when using for a long time, this radiating mode just can be not enough because of the heat radiation time, and the injury lamp or the device of projector inside.
On the other hand, if undesired shutdown or interim outage when the last time is used projector, when projector opens, amount of residual heat will will be stayed projector inside.Therefore, if the user is when opening (reboot) again immediately, and general radiating mode just restarts action after all forcing projector's running earlier one period schedule time, may residue in the heat of projector inside to shed.This similarly can cause the user to lose time.And, if undesired shutdown last time may be with at present again the time interval of start for a long time, do not need so heat radiation that repeats.On the other hand, if through after long-time the use, because undesired shutdown makes that the inner high heat of projector can't dissipation, and the predetermined heat radiation time may also be not enough to abundant heat radiation, will cause the heat start unsuccessful, and projector can't start.Therefore, known projector is unable to cope with various operating position for the control method of heat radiation time, causes in the use quite inconveniently, even can cause the infringement of projector.
Therefore, the utmost point need a kind of can be according to the various operating positions of projector, and flexibly adjust cooling control method and the device of the heat radiation time of inner radiation device.
