PROBLEM TO BE SOLVED: To provide engine cooling equipment wherein the capacity of an exhaust gas heat exchanger is improved. SOLUTION: In the engine cooling equipment 1, a cooling water circuit 40 is so constituted that cooling water accelerated by a cooling water pump 39 circulates to this pump 39, flowing sequentially through an engine 13, a first three-way valve 41, a second three-way valve 42, a heat-recovery heat exchanger 33, a first joining part 43 wherein the cooling water branched by and flowing from the second three-way valve 42 joins, a radiator 22 and a second joining part 44 wherein the cooling water branched by and flowing from the first three- way valve 41 joins. In this constitution, the exhaust gas heat exchanger 50 conducting recovery of heat of the exhaust gas of the engine 13 is provided in the cooling water circuit 40 between the radiator 22 and the second joining part 44. |
