With the widespread popularity of digital film projectors, more and more models and brands are used in digital projectors, and the degree of new and old equipment and the age of use are also greatly different. Therefore, the maintenance and maintenance of digital projectors is particularly important.

 

Heat Dissipation of Digital Projector

 

 

 

Digital projector is different from film projector. It has high integration, strong sealing, difficult radiation of projector, and high requirements for radiation of projector. The heat dissipation of digital projectors mainly includes several aspects:

 

 

 

1. Heat dissipation of xenon lamp. The xenon lamp has high power, high heat and thin glass shell. When the lamp is ignited, dozens of atmospheric pressure will be generated in the lamp. If the heat dissipation is not good, it will easily cause the explosion lamp. The explosion lamp not only damages the lamp, but also damages the expensive matching reflector.

 

 

 

2. Heat dissipation of DLP chips. DLP chip is the core component of digital projector imaging. It belongs to the device with high precision and can't be polluted by half dust. So it has good sealing ability. Three DLP chips are assembled in three engines, and there is no direct contact with outside space. This brings serious heat dissipation problem. DLP chip receives xenon lamp. The brightness of the screen is determined by the reflected light of three LP chips less than two inches. The heat of the chip will be very high. If the heat dissipation of the chip is not good, the chip will rapidly aging or damage.

 

 

 

Third, the heat dissipation of the circuit. Digital projector circuit integration is high, and in the high heat projector shell, circuit work is most afraid of working environment temperature is too high, so projector circuit also needs good heat dissipation to work properly.

 

In order to solve the heat dissipation of the above main parts and ensure that all parts can work at normal ambient temperature, the digital projector has high requirements for heat dissipation and has taken many effective measures, but whether these requirements can be achieved depends not only on rigorous installation of debugging equipment according to requirements, but also more importantly. It depends on the maintenance of projection equipment by projectors at ordinary times.
