Description

technical field [0001] The invention relates to the technical field of heavy-duty trucks, more specifically, to a heating device for a cab of a heavy-duty truck and a heavy-duty truck using a graphene heating film. Background technique [0002] At present, the temperature control of the cab of heavy trucks mainly adopts the PTC warm air heating system. The system consists of a 700V high-voltage PTC warm air heater, a high-voltage DC relay, and a temperature protection switch. The existing scheme exchanges the PTC heater with the cab warm air core. However, the main problems of this solution are high heating energy consumption, safety risks in DC high-voltage heating, poor overall heating temperature uniformity of the cab, and small adjustable heating power range, which is easy to overheat. [0003] In the prior art, graphene has become an ideal heating film material due to its excellent mechanical properties, electrical properties and optical properties. At present, the com...
