Strong heat dissipation case

The invention discloses a strong heat dissipation case. The case comprises a box body, a mainboard, a driver, a heat dissipation fan, a controller and a power supply. The mainboard is arranged on the backboard of the box body. The mainboard is connected with the driver. The driver is connected with a right side board of the box body. The power supply is arranged at a joint of the left side board and the bottom board of the box body. The heat dissipation fan is arranged on the left side board of the box body at a location opposite to the mainboard. The controller is arranged on the left side board of the box body at the location close to the power supply. The controller is arranged at the location lower than the heat dissipation fan. The heat dissipation fan is connected with a power supply circuit through the controller. The controller comprises a metal shell, an input power wire, an output power wire and a flaky temperature sensing element. According to the design, the heat dissipation efficiency is relative
