COOLANT DEVICE AND HEAT MANAGEMENT SYSTEM

Abstract

Among other things, a coolant device is provided that achieves compactness while simultaneously counteracting the complexity of a heat transfer fluid flow path. It comprises a housing body 1, which forms flow paths C1-C5 through which a heat transfer fluid flows; a four-way valve 70 and an eight-way valve 71 as multi-way valves, which are provided on the housing body 1 and switch the flow path of the heat transfer fluid on the flow paths C1-C5 by rotating about their own valve shaft; and a first pump 3a, second pump 3b, and third pump 3c, which are provided on the housing body 1 and convey the heat transfer fluid on the flow paths C1-C5 under pressure, wherein the first pump 3a is provided on a first housing body side surface 1a, which faces one side of a lateral direction D1 intersecting the axis of rotation of the multi-way valves 70, 71.the second pump 3b is provided on a second housing body side surface 1b, which faces the other side of the width direction D1, and the third pump 3c is provided on the first housing body side surface 1a in a height direction D3 intersecting the width direction D1 next to the first pump 3a.
