PROBLEM TO BE SOLVED: To improve the controllability of refrigerant behavior in a cooler.SOLUTION: A refrigerant flows in a refrigerant passage (101). A cooling part (102) is disposed in the refrigerant passage (101) and thermally contacts with a heating component (200). The refrigerant passage (101) is provided so that an upstream side passage part (111), into which the refrigerant flows, is disposed above a downstream side passage part (112), from which the refrigerant flows, in a vertical direction. |
