Cooling apparatus

Abstract

A cooling apparatus 1 includes: a cooling circuit 100 that includes three flow passages intersecting at an intersection point and allows a cooling liquid to circulate therethrough; a three-way valve 8 that is disposed at the intersection point and is switchable such that any two of the three flow passages communicate with each other; and a controller 9 that controls switching of the three-way valve 8. The controller includes an intermediate fixation determination unit. The intermediate fixation determination unit determines that the three-way valve is in an intermediate fixation state in which the three flow passages simultaneously communicate one another, when a cooling liquid temperature difference between one of the two flow passages that are controlled to communicate with each other, and a remaining flow passage of the three flow passages that is not controlled to communicate, is smaller than a predetermined value.
