Thermal management system for whole electric excavator
The invention relates to the field of engineering machinery, in particular to an electric excavator complete machine heat management system which comprises an oil radiator and a condenser matched with the oil radiator, the oil radiator is connected with a first heat exchanger through a pipeline to form a heat supply loop, and the oil radiator is connected with a proportional valve through a pipeline to form a control loop. A first distribution valve is installed on the heat supply loop and connected with a first heat exchanger through a branch pipeline, and the first heat exchanger is connected with a cab through a heat dissipation pipeline to form a first cab heat dissipation loop to dissipate heat of the cab. The first heat exchanger is connected with the battery through a pipeline to form a first battery heat dissipation loop to dissipate heat of the battery. According to the complete machine heat management system of the electric excavator, heat generated by a hydraulic oil circuit is conveyed to a battery and a cab according to actual requirements, heating of the cab and preheating of the battery in winter are met, and the heat is recycled; and the connection of a set of condenser is reduced, so that the utilization rate of the refrigerant is improved.
本发明涉及工程机械领域，具体涉及一种电动挖掘机整机热管理系统，其包括油散热器和配合油散热器的冷凝器，油散热器通过管路连接第一热交换器形成供热回路，油散热器通过管路连接比例阀形成控制回路，供热回路上安装有第一分配阀，第一分配阀通过分支管路连接第一热交换器，第一热交换器通过散热管路连接驾驶室并形成第一驾驶室散热回路对驾驶室进行散热，第一热交换器通过管路连接电池形成第一电池散热回路对电池进行散热。该电动挖掘机整机热管理系统将液压油路产生的热量依据实际需求输送给电池和驾驶室，满足冬季驾驶室的供暖以及电池的预热，将热量回收利用；并且减少了一套冷凝器的连接，提升了对于冷媒的利用率。
