The invention discloses a heat management system applied to a new energy commercial vehicle and the new energy commercial vehicle, and relates to the technical field of vehicle heat management. Wherein the compressor, the out-vehicle condenser, the first cooler, the second cooler, the gas-liquid separator, the in-vehicle evaporator, the motor, the radiator, the motor water pump, the heater, the second cooling close attaching piece, the passenger compartment heater, the battery water pump, the battery, the first cooling close attaching piece, the first expansion water tank, the second expansion water tank and the like are connected with one another through a plurality of valves; and a heat pump loop and a battery motor cooling loop are formed. Refrigerant circulates in the heat pump loop, and cooling liquid circulates in the battery motor cooling loop, so that heat management of the battery, the motor and the passenger compartment is achieved. In addition, the passenger compartment heater can directly utilize waste heat of the motor for heating. Therefore, the system can realize thermal management of the battery, the motor and the passenger compartment only by virtue of one thermal management system, and is high in reuse rate of parts, high in thermal efficiency and low in cost.
