The invention relates to the field of engineering machinery, and discloses a vehicle heat management system which comprises a battery pack heat exchange loop, a hydraulic oil heat dissipation loop and a heat supply heat exchanger, and the battery pack heat exchange loop comprises a battery pack heat exchanger used for exchanging heat with a battery pack of a vehicle to cool or heat the battery pack. The hydraulic oil heat dissipation loop is used for dissipating heat of hydraulic oil of a vehicle, the heat supply heat exchanger comprises a battery pack side heat exchange pipeline and a hydraulic oil side heat exchange pipeline, the battery pack side heat exchange pipeline is arranged on the battery pack heat exchange loop, and the hydraulic oil side heat exchange pipeline is arranged on the hydraulic oil heat dissipation loop; the heat supply heat exchanger can transfer heat of hydraulic oil in the hydraulic oil heat dissipation loop to the battery pack heat exchange loop through heat exchange of the battery pack side heat exchange pipeline and the hydraulic oil side heat exchange pipeline when the battery pack heat exchange loop supplies heat. Waste heat generated by the hydraulic oil heat dissipation loop is used for heating the battery pack through the heat supply heat exchanger, the energy consumption of a heat management system of the vehicle is greatly reduced, and the energy-saving effect is achieved.

    本发明涉及工程机械领域,公开了一种车辆的热管理系统,包括电池包换热回路、液压油散热回路以及供热换热器,电池包换热回路包括用于与车辆的电池包换热以对电池包进行冷却或加热的电池包换热器,液压油散热回路用于对车辆的液压油进行散热,供热换热器包括电池包侧换热管路和液压油侧换热管路,电池包侧换热管路设于电池包换热回路,液压油侧换热管路设于液压油散热回路,供热换热器能够在电池包换热回路供热时将液压油散热回路内的液压油的热量通过电池包侧换热管路和液压油侧换热管路的热交换传递至电池包换热回路。本发明通过供热换热器将液压油散热回路产生的余热利用至电池包的加热,大大降低了车辆的热管理系统能耗,达到节能的效果。
