This summer season not only has hot weather, but also fiery movies. In addition to "I am not a drug god", as of yesterday, the harvest of 2.427 billion box office results, Jiang Wen four years of masterpiece "Evil is not pressing", happy twist "Xihong City richest man", Xu High-quality movies such as "Die Renjie's Four Kings" are also expected to become explosions, harvesting box office. Then, in the hot summer days, how to prevent high-intensity projectors in high-temperature environment to prevent 'heatstroke' and avoid causing projection failures, do you make it? NEC will explain the projector cooling system for you today and offer you the most effective 'Solutions of the Summer'.
Traditional heat dissipation methods have obvious drawbacks
In the past, Studios has been using differential pressure to dissipate heat, which is to install an additional ventilation system for the projector to remove the heat generated by the projector and discharge it to the outside. This method can effectively dissipate heat for the projector, but because of the air in the projection room. Being discharged to the outside, the air pressure in the projection room is lower than that in the outdoor. The negative pressure causes the outdoor air to continuously flow into the projection room, which in turn brings a lot of dust to the projection room, and also brings in the unorganized external high temperature air. The accumulation of optical components in the projector will reduce the heat dissipation efficiency inside the machine. The quality of the projector will be seriously affected over time, and the stability of the projector will be threatened. The high temperature air will make the temperature of the projection room impossible. Control, the temperature is also difficult to come down.
In the Xenon era, due to the high heat release of the bulb, we had to install an exhaust system to accelerate the auxiliary heat dissipation. In the laser era, most projectors still use this heat dissipation method. Why is the new light source technology still unable to improve the traditional heat dissipation method?
Optimized cooling method is better
Before answering this confusion, let's first understand the diffuse heat dissipation of cold air. The most common thing we get is the cooling of the air conditioning system. The air conditioner installed in the projection room recovers the heat generated by the projector and other heat dissipation equipment (such as power amplifier), and also goes to the equipment room. Adding the same amount of cold air. This kind of screening room circulation can not only ensure the cooling demand in the space, but also maintain a certain positive pressure in the projection room to ensure the air cleanliness. It is more suitable for projectors, especially laser projectors.
Speaking of this, some readers will ask if the heat recovery of air conditioners can meet the heat dissipation requirements of laser projectors. We know that the working temperature of laser light sources is lower than that of xenon lamps, and most of the energy is converted into visible light. The heat radiated to the outside is drastically reduced compared to the xenon lamp machine, which allows us to get rid of the 'simple and rude' cooling method of the exhaust fan, and only maintain the better operating temperature by relying on the air conditioning system.
NEC fits perfectly with the air conditioning cooling system
It is also due to this reason. At the same time, relying on the development of laser technology, through NEC's continuous exploration and innovation, NEC believes that for optimizing the laser light source and the own cooling system of the projection room, the heat dissipation structure of the projector should also be innovated. NEC laser projector relies on it. The unique CCT dual-cavity sealing and cooling patent technology realizes the self-discharge of the projector, completely abandoning the auxiliary exhaust system, and presents the advantages of the laser to the user from the aspect of screening quality and operation and maintenance. See here, have you gradually released? Confused before? If the laser projector you choose is still using the traditional cooling method, is it a true laser projector?
Correct projector maintenance method
In addition to scientific and reasonable heat dissipation design, NEC has prepared three projector maintenance methods for you to effectively improve the heat dissipation efficiency of the projector and extend the life of the projector.
Install the air conditioner correctly and control the ambient temperature of the projection room. Control the temperature of the booth to 20-25 degrees to ensure that the projector will not be turned on due to the low or too high operating environment temperature, or the shutdown will occur due to an error during operation. When installing the air conditioner, it should be avoided to directly blow the cold air directly onto the surface of the equipment or other solid surface to prevent the condensation of water and moisture on the surface and inside of the machine, causing short circuit and corrosion of the circuit.
Regular cleaning, replacement of the filter screen. If the air cleanliness and humidity exceed the standard, the efficiency of the air passing through the filter will be reduced, which will affect the heat dissipation of the projector. Therefore, it is recommended to clean or replace the filter regularly to ensure the cleanliness of the filter. NEC The laser projector uses a metal filter that can be directly cleaned for reuse without frequent replacement.
Regular maintenance and maintenance of the fan. After the air passes through the filter, it will enter through the fan, and the efficiency of the intake air depends mainly on the fan speed and the state of the fan blade surface. Therefore, check the fan regularly and observe the status of the machine. The problem should be promptly dial 4008900678 to the 3rd key to communicate with the NEC manufacturer.
The strongest summer file in history is coming. If you want your projector to work for you, just take the NEC 'Solutions of the Summer' and make a summer vacation for your projector!
