Description

A high-efficiency energy-saving cooling device for projector

technical field

The utility model relates to the technical field of auxiliary equipment for projectors, in particular to a high-efficiency energy-saving heat dissipation device for projectors.

Background technique

Projectors are widely used in homes, offices, schools and entertainment venues. Projectors generally have a wide operating voltage, and the input voltage of the projector can maintain normal operation between 90V and 250V. When the rated power of the projector is fixed, the lower the input voltage is, the greater the current of the power supply will be. The heat generated by the projector power supply through the internal resistance increases the temperature of the power supply, and the temperature rise will cause the temperature of the electronic components on the power supply motherboard to increase.
