Working Machine and Temperature Management System Thereof

Abstract

Problem: Provide a temperature management system of a working machine that can manage heat by utilizing the heat of hydraulic fluid in a power saving manner while preventing an increase in back pressure, and a working machine including the same. Solution: A temperature management system of a working machine comprises a return line that returns hydraulic oil to a tank a back pressure check valve provided in the return line and providing back pressure to return oil, a diversion line that diverts a portion of the return oil from an upstream side of the back pressure check valve in the return line a coolant line that circulates a coolant used in a heating device that heats an interior of a cab, and a heat exchanger that exchanges heat between the diversion line and the coolant line.
