Cooling Projectors

What’s a Projector?

A projector is a sophisticated electronic device whose technology has improved by leaps and bounds over the past ten or so years, and continues to do so even today. Companies that produce projectors are constantly trying to outdo each other when it comes to improving technology, lowering costs, enhancing features, and boosting usability.

But despite all the advancements in projector technology made over the years, projectors still tend to overheat on occasion. In fact, close to 98% of all projectors on the market today sport traditional lamps and bulbs as their light sources. Both of these light sources can emit copious amounts of heat. These bulbs and lamps easily reach temperatures of 200 degrees to 300 degrees. Because of the amount of heat produced by these lamps and bulbs it is important to keep the area surrounding your projector open and free of clutter so as not to restrict or limit airflow in and out of the machine which helps with cooling. When it comes down to it, a projector has two basic needs – airflow for cooling and a steady power supply.

Cooling Projectors and Keeping Them in Top Condition

Of the two main requirements for keeping a projector in top working condition, a steady power supply is the easier to fulfill. Though it is generally easy to obtain a steady power supply, recent studies have shown an increase in premature projector failure that can be blamed on a faulty power supply. A faulty or inconsistent power supply can cause the bulb of a projector to overheat, thereby drastically reducing its power supply and making for shorter bulb life. To solve the problem of unstable power supplies causing damage to projectors, opt for an accessory that will help stabilize and keep its power supply consistent before it reaches the projector.

The second and most important element in keeping your projector in mint working condition through its lifespan is clean air and a high quality cooling fan. Though it might seem more important to have a good power supply than fresh air, as without the power the air becomes redundant to a projector, it is imperative for an operating projector to have a continual and cooling airflow passing through it. Projectors can literally shut down in a few minutes or seconds if they should become too overheated. Due to the intense heat produced by projector bulbs and lamps, projectors must be actively cooled in order to prevent overheating. An overheating project can experience unexpected shutdown and can even cause the bulb to deteriorate quickly or explode. Even if such dramatic damage is not caused, overheating will shorten the lifespan of any projector.

Tips for Cooling Projectors and Preventing Premature Damage

Below you will find a few tips that will help you properly cool and prolong the lifespan of you projector.

Maintain Airflow:

Do not under any circumstances block or restrict the airflow available to projectors. A projector comes preinstalled with a cooling fan that cools the bulb or lamp as well as the rest of the components in the machine, but for the fan to work the area around the projector needs to be free of clutter. Do not put your projector in any nook or cranny but place it in an open area when in use so that it gets airflow from all sides. To keep your projector’s fan working at maximum efficiency, ensure that it is regularly cleaned of dirt and dust buildup. If cleaning does not restore effective function to your cooling fan, you may need to replace it. You’ll find a variety of high quality cooling fans available through NMB.

Prevent Overheating:

If a projector bulb overheats, it can quickly burn out and affect the lifespan of the entire machine. Besides having a blockage of airflow or an ineffective cooling fan, another reason a projector may overheat is if its filter becomes too dirty. As a broad rule, the filter within a projector needs to be cleaned at least once every three months. If the projector is being used in a dusty environment, it should be cleaned more often. The filter can easily be cleaned with a can of compressed air. Never touch the projector lamp, as the natural oil on your fingers can cause damage to the lamp. Be sure only to touch the metal housing around the projector lamp or bulb.
