Temperature control method and device for projector

Abstract

The invention relates to a temperature control method and device of a projector, which are used for monitoring the temperature of each working unit in the projector in real time, and heating or cooling the working unit when the temperature exceeds the working temperature range of the working unit; therefore, the working unit can be maintained at the optimum working temperature in various working environments, and the service life of the working unit is further prolonged.

Description

technical field [0001] The invention relates to the technical field of projector temperature control, in particular to a projector temperature control method and device. Background technique [0002] The operating temperature of existing projectors is generally between 0°C and 40°C, and they are mostly used indoors or semi-outdoors. Even for engineering projectors used outdoors, their operating temperature is between 0°C and 40°C. To meet the requirements of outdoor low temperature or harsh working environment, a casing needs to be covered on the outside of the projector equipment. The enclosure is a constant temperature and humidity chassis; at the same time, the interior of the chassis needs to be equipped with additional equipment such as air conditioners and distribution boxes. This kind of projector has the disadvantages of complex system, high cost, large space occupation, large amount of on-site construction, long construction period and high cost, and high maintenan...

AI Technical Summary

Problems solved by technology

This kind of projector has the disadvantages of complex system, high cost, large space occupation, large amount of on-site construction, long construction period and high cost, and high maintenance cost in the later stage.

At the same time, the surrounding environment of the device is affected during the use of the device, which greatly limits the use of the projector.
