With the development of science and technology, technology is changing with each passing day, and people invented a new type of head-mounted display. This display can be used as a magnified image on the micro-display, projecting the image on the retina, and then presenting the image on the large screen in the eyes of the viewer. The image point is to look at the object with a magnifying glass to show an enlarged virtual object image. However, in the development of head-mounted displays, cooling solutions must also continue to evolve and improve.
The sea star and the cooling fan match the flow channel design to direct the air flow to the parts of the power supply, so as to reduce the temperature of the internal parts and increase the life of the display.
