Friends who have used projectors will easily find a phenomenon that when standing next to a projector, you will feel gusts of hot air. So have you ever wondered why a projector gets hot? This article will explain the phenomenon of projector heating and how to effectively dissipate heat.
01
Why does the projector heat up?
A very important component of the projector is the bulb. One of the first conditions for a projector to have a clear picture is that it must have sufficient brightness, so the bulb power of many projectors is very high.
So when we turn on the projector, the bulb starts to run in the small space inside the projector. It takes about two hours or even longer to watch a movie with a projector. Such long-term work will cause the projector bulb to generate huge heat.
However, the projector has its own cooling fan. When the projector generates heat, the cooling fan will also dissipate the heat, so the heat dissipation holes of the projector will discharge a lot of hot air, which is a very normal phenomenon.
Due to the development of the intelligent era, the projector industry has produced many projectors with built-in intelligent systems in response to the use requirements of most people, which has led to an increase in the accessories inside the projector. When the projector is working, each accessory will generate heat, and the heat of the projector will naturally increase a lot.
However, the heat generated by the above projectors is within the normal range, that is, the heat emitted by the projector is felt to be warm. But sometimes when we touch the projector, we feel that the shell of the projector is very hot, which may be a problem with the cooling system of the projector.
If the projector works for too long, for example, the projector has been working for five or six hours, then its heat dissipation rate will be greatly reduced, and the heat accumulated inside will not be eliminated, which will cause the shell of the projector to heat up or even get hot. Or the heat dissipation holes of the projector are blocked, resulting in the heat of the projector not being dissipated, and the internal heat accumulation will also cause the body shell of the projector to heat up.

How to effectively dissipate heat from a projector
If the projector does not dissipate heat in time, many problems will arise. From a small perspective, if the projector is operating at high temperature for a long time, the working efficiency of the projector will be greatly reduced and the life of the projector will be shortened. What's more, if the projector fails to dissipate heat well, the heat will continue to increase in the space inside the projector, which may cause the projector's lens, display chip, optical machine and other components to be burned. Therefore, the heat dissipation of the projector must be done well. We can ensure effective heat dissipation of the projector through the following aspects:
1. Installation environment
When we buy a projector, whether we place it directly on a cabinet or use various installation methods such as hanging or wall mounting, we need to place the projector in a ventilated environment, and do not pile up other debris around and on the projector. We can turn on the projector, feel the position of its heat dissipation vent with our hands, and then place the side of the heat dissipation vent in an open environment. And do not place the projector in a high temperature environment, which is not conducive to the heat dissipation of the projector.
2. Regular cleaning
Since the heat dissipation vents of most projectors are hollow designs, the circulation of air will cause a lot of dust to accumulate at the vents. If it is not cleaned for a long time, the air inside and outside the projector will be blocked, that is, the heat dissipation rate of the projector will decrease, and the projector will naturally get hot. Therefore, we need to regularly clean the dust and debris inside the projector. Generally, we can go to a place specializing in projector repair to disassemble and clean it.
3. Ensure heat dissipation
The continuous working time of the projector should not exceed four hours. As mentioned above, if the projector is working for too long, the heat dissipation function will be weakened. So try not to turn on the projector all day or never turn it off. When the projector needs to run for a long time, it is best to let the projector rest for about half an hour every four hours, so that the projector can cool down and ensure its heat dissipation rate.
In addition, don't rush to cut off the power of the projector when we are not using it, because when the power is turned off, the cooling fan of the projector will stop working, and the residual heat inside the projector will have no way to dissipate. We should first use the remote control or the top power off button to turn off the projector, wait for the cooling fan to dissipate all the residual heat inside the projector, and then cut off the power.
