A lighting cooling device based on thermoacoustic effect

Abstract

The invention discloses a light heat dissipation device based on thermoacoustic effect, which comprises a resonance tube, a plate stack module, a heat dissipation module, a sound absorption module and a light module to be radiated. The resonance tube includes a front resonance tube and a rear resonance tube. The lighting module is set in the front resonance tube, and the plate stack module is set at the intersection of the front resonance tube and the rear resonance tube. The cold end of the plate stack module is in close contact with the heat-generating components of the light module for heat exchange, and the heat dissipation module and the hot end of the plate stack module It is used to dissipate the heat from the hot end of the plate stack module to the air. The sound absorption module is located at the rear end of the resonance tube to absorb the external sound and intercept the sound waves of the required frequency and transmit them to the resonance tube. The sound waves in the front and rear resonance tubes are due to The interference effect forms a standing wave, so that the heat generated by the light module is continuously transported from the cold end of the board stack module to the hot end, and exchanges heat with the outside through the heat dissipation module. The invention does not need additional power, has no noise in heat dissipation, and is safe, energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the mechanical field, and relates to a light heat dissipation device, in particular to a light heat dissipation device based on a thermoacoustic effect. Background technique [0002] Theatrical performances and stage performances are increasingly becoming an important part of people's lives. According to the survey, more than 2,000 theaters have been built and put into use in my country, including more than 1,000 professional theaters, and each theater holds more than 46 performances of various types every year on average. [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 lamps will generate a lot of heat under long-term high-intensity operation. If the heat cannot be dissipated ...

AI Technical Summary

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
