CN-121989664-A - Thermal management of hybrid mining trucks

Abstract

Thermal management of hybrid mining trucks. A mining truck may include a resistive grid, an electronics unit, and a thermal management system located on a platform of the mining truck. The thermal management system may include an air transfer region disposed between the resistive grid and the electronic unit. The air delivery region may be configured to receive exhaust air from the resistive grid. The thermal management system may further include one or more heat exchangers positioned above the resistive grid. The one or more heat exchangers may be configured to receive a cooling fluid for cooling one or more electronic components of the mining truck.
