Lamplight cooling device based on thermo-acoustic effect

Abstract

The invention discloses a lamplight cooling device based on a thermo-acoustic effect. The lamplight cooling device comprises a resonant tube, a plate stack module, a cooling module, a sound absorptionmodule and a to-be-cooled lamplight module. The resonant tube comprises a front resonant tube body and a rear resonant tube body, the to-be-cooled light module is arranged in the front resonant tubebody, and the plate stack module is arranged at the intersection of the front resonant tube body and the rear resonant tube body. The cold end of the plate stack module is tightly attached to a heating part of the lamplight module for heat exchange, and the cooling module is connected with the hot end of the plate stack module and used for dissipating heat of the hot end of the plate stack moduleinto air. The sound absorption module is arranged at the rear end of the resonant tube and used for absorbing external sound and intercepting sound waves of a needed frequency to be transmitted into the resonant tube, sound waves form standing waves in the front resonant tube body and the rear resonant tube body due to the interference effect, and therefore heat generated by the lamplight module is continuously transmitted to the hot end through the cold end of the plate stacking module and exchanges heat with the outside through the cooling module. The lamplight cooling device does not need extra power, is free of noise during cooling and safe, saves energy and protects the environment.

Description

Technical field[0001]The invention belongs to the field of machinery, and relates to a light heat dissipation device, in particular to a light heat dissipation device based on a thermoacoustic effect.Background technique[0002]Drama performances and stage performances have increasingly become an important part of people's lives. According to the survey, there are more than 2,000 theaters in my country that have been built and put into use, including more than 1,000 professional theaters. Each theater holds an average of more than 46 performances each year.[0003]The increase in stage performances is followed by the extensive use of various lighting equipment. In order to achieve better performances, performance organizers will use various types of lights. These lighting equipment are generally high-power LEDs. high strength. However, high-power LED lights will generate a lot of heat under long-term high-intensity operation. If this heat cannot be dissipated in time, it will greatly re...

Problems solved by technology

In the actual use of these two methods, the heat dissipation efficiency is not high

And when the heat is dissipated by the fan, the fan part will generate a large cutting wind noise, which will affect the viewing experience of the audience
