Battery Thermal Management System of Construction Machinery and Construction Machinery Having The Same
The present invention relates to a battery heat management system for construction machinery to maintain the temperature of a construction machinery battery in low-temperature environments and construction machinery including the same. According to the present invention, the battery heat management system for construction machinery comprises: a fan discharging air inside a battery compartment to the outside or supplying air outside the battery compartment to the inside; a heat exchanger absorbing heat while cooling heated hydraulic oil; and an opening/closing membrane controlling air flow between the battery compartment and a motor compartment according to the direction of the air. The fan allows the air outside the battery compartment to pass through the heat exchanger to increase the temperature of the air and supplies the air with an increased temperature to the battery compartment to increase the temperature inside the battery compartment. The opening/closing membrane is closed when the air outside the battery compartment is supplied to the inside, so that the flow of air from the battery compartment to the motor room can be blocked.
본 발명은 배터리 열관리 시스템 및 이를 포함하는 건설기계에 관한 것으로, 배터리룸 내부의 공기를 외부로 배출하거나, 배터리룸 외부의 공기를 내부로 공급하는 팬; 가열된 작동유를 냉각하면서 열을 흡수하는 열교환기; 및 공기의 방향에 따라 배터리룸과 모터룸 사이의 공기 흐름을 제어하는 개폐막;을 포함하고, 상기 팬은, 배터리룸 외부의 공기가 상기 열교환기를 지나게 하여 공기의 온도를 높이고, 온도가 올라간 공기를 배터리룸으로 공급하여 배터리룸 내부의 온도를 높이며, 상기 개폐막은, 배터리룸 외부의 공기가 내부로 공급될 때 닫혀 배터리룸에서 모터룸으로의 공기의 흐름을 막을 수 있다.
