PROBLEM TO BE SOLVED: To provide a technique for suppressing a decrease in cooling performance.SOLUTION: A cooler 100 includes partition separators 3, 6 which separate a flow passage through which a refrigerant flowing in from one end side makes a turn on the other end side to return to the one end side into an outward path 91 and a return path 93 before or after the turn part, and can be divided by a division plane crossing both the outward path 91 and return path 93 in the direction of a flow 90 of the refrigerant. Division planes 33, 63 of the lower separator and upper separator are corrugated in the direction of the flow 90 of the refrigerant. Consequently, even when there is a gap S between the upper separator and lower separator, the direction of the flow 90 of the refrigerant flowing in the gap S is substantially parallel with or at acute angles to flow passage planes 31, 32 and 61, 62 of the upper and lower separators. Consequently, the division planes 33, 63 orthogonal to the flow passage planes 31, 32 and 61, 62 are obstacles to the course of the refrigerant, so the refrigerant flowing in the gap S decreases in flow rate. The refrigerant is suppressed from decreasing flow rate at a downstream part of the outward path 91 and at the turn part 92. |
