Electronic equipment chassis

Номер: CN0101583255A
Автор: ZHANG ZIBING, ZIBING ZHANG
Принадлежит:

The invention discloses an electronic equipment chassis and a radiating method thereof. By carrying out a splitting design to the installation of the electronic equipment chassis and a radiating part of a fan, the electronic equipment is arranged in a sealed area; a heat and good conductor material is adopted to tightly connect the sealed area and a radiating area in a back-to-back mode; the heat generated by the electronic equipment in the sealed area is taken away by the fan in the radiating area, thus reducing the temperature of the working area of the electronic equipment, namely, the sealed area, and realizing the purpose of radiating heat with high efficiency. The electronic equipment chassis can lead the electronic equipment to have the characteristics of dust prevention, rainproof performance and good electromagnetic compatibility.
