Case with built-in two-fluid wind channels

The invention discloses a case with built-in two-fluid wind channels. The case includes a box body, a main board, an optical drive, a power supply, a heat dissipation fan, a controller, an air-permeable film and a power distribution box. The box body includes a front panel, a rear panel, a top panel, a bottom panel, a front plate and a back plate. The optical drive is disposed on the front panel.The main board is disposed on the back plate. The power supply is disposed at a junction place of the rear panel and the bottom panel. A drive fan is disposed on the bottom panel. The heat dissipationfan is disposed at a place of the rear panel near the top panel, and is connected with a power supply circuit through the controller. The controller includes a metallic outer shell, an input power supply line, an output power supply line, a fixed beam, a rotating beam, a moving conductive column, a fixed conductive groove and a wax block. According to a design of the invention, heat dissipation efficiency is higher, and c
