AI Technical Summary
High temperatures can cause a decrease in the brightness of the light source module and color distortion in projection equipment, shortening the equipment's lifespan and potentially causing malfunctions.
The system employs a liquid-cooled light source module and a liquid-cooled display module, combined with a coolant circulation module. The coolant absorbs heat from the LED chips, LCD screen, and light-transmitting components, achieving liquid cooling and keeping the optomechanical module operating within a healthy temperature range.
It effectively reduces the temperature of the optomechanical module, prevents aging, extends the service life of the equipment, and ensures display quality and equipment stability.
