Chassis controller mounting device and heat dissipation method

The invention relates to the technical field of commercial vehicle chassis controllers, in particular to a chassis controller mounting device and a heat dissipation method. The chassis controller mounting device comprises a controller box, a radiator, an altitude sensor, a temperature sensor and a heat dissipation controller, the controller box is used for being arranged on a chassis so as to install a chassis controller. The radiator is arranged in the controller box and is used for discharging heat in the controller box; the altitude sensor and the temperature sensor are respectively used for acquiring the altitude of the vehicle and the environment temperature of the chassis controller; and the heat dissipation controller is used for controlling the power of the heat dissipation device according to the altitude of the vehicle and the temperature in the controller box. The problems that in the prior art, the rotating speed of a radiator is only high or low, heat dissipation of a chassis controller is unbala
