COOLING SYSTEM FOR CONSTRUCTION MACHINE

摘要

PURPOSE: A cooling system for a hybrid construction machine is provided to remove the need for an anti-overheating device and a heater and reduce volume since the circulating path of engine cooling-water changes and thus the overheating of a hybrid system is prevented and the hybrid system is preheated. CONSTITUTION: A cooling system for a hybrid construction machine comprises hybrid radiators(21), an engine radiator(23) and a first pipe. The hybrid radiator cools hybrid cooling-load using hybrid cooling-water. The engine radiator cools the engine using the engine cooling-water. The first pipe is connected to the inlet end of the engine radiator and is connected to the outlet end of the engine radiator. The first pipe passes through the hybrid radiator.
