Abstract: A heat dissipation apparatus is provided. The heat dissipation apparatus includes an immersion tank. The immersion tank accommodates a liquid medium. When being used, the board is immersed in the liquid medium, and the liquid medium dissipates heat for the board by absorbing heat. The heat dissipation apparatus further includes a condenser immersed in the liquid medium. The condenser is disposed to dissipate heat for the liquid medium. Heat of the board is transferred to the condenser in the immersion tank by using the liquid medium in the immersion tank as a medium. Then the condenser takes away and dissipates the heat by using a cooling apparatus that is connected to the condenser and that is configured to perform heat exchange for the condenser.
