The invention provides an electric engineering vehicle and a thermal management system thereof, and belongs to the technical field of vehicle thermal control. The system comprises a refrigeration main circuit, an air conditioner refrigeration branch circuit and a battery refrigeration pipeline, the refrigeration main circuit comprises a compressor and a condenser which are connected with each other, and the system further comprises a first cooling fan for cooling the condenser. The other end of the battery refrigeration pipeline is connected with the condenser through a first expansion valve; one end of the air-conditioning refrigeration branch is connected with the compressor inlet, and the other end is connected with the condenser through the second expansion valve. By the adoption of the electric engineering vehicle, the refrigeration requirement of a battery in the electric engineering vehicle can be met, the normal air conditioner refrigeration function can also be met, meanwhile, the number of equipment such as compressors and condensers is reduced, cost is reduced, and meanwhile the requirement for the whole vehicle space is lowered.
本发明提供了一种电动工程车辆及其热管理系统,属于车辆热控制技术领域。系统包括制冷主路、空调制冷支路和电池制冷管路,制冷主路包括相互连接的压缩机和冷凝器,还包括为冷凝器散热的第一散热风机。电池制冷管路的一端连接压缩机入口,另一端通过第一膨胀阀连接冷凝器;空调制冷支路的一端连接压缩机入口,另一端通过第二膨胀阀连接冷凝器。采用本发明,既可以满足电动工程车辆中电池的制冷需求,也能满足正常的空调制冷功能,同时减少压缩机、冷凝器等设备的数量,降低了成本,同时降低了对整车空间的要求。
