Title: POWER CONVERSION DEVICE
Abstract:
This power conversion device (1) has: a heating element (2); a case (3) provided with a cooling wall part (31) on which the heating element (2) is held, and accommodating the heating element (2); a flow path cover (4) provided with an opening (41) and covering a surface on the opposite side of the side on which the heating element (2) is held on the cooling wall part (31); and a rising part (32) which rises from the cooling wall part (31) and is inserted into the opening (41). A flow path side wall part (33) is provided in at least one among the cooling wall part (31) and the flow path cover (4), and rises toward the other. Also, the power conversion device (1) has a refrigerant flow path (5) surrounded by the cooling wall part (31), the flow path cover (4), and the flow path side wall part (33). In a peripheral edge portion of the refrigerant flow path (5), seal materials (6) close a gap between the cooling wall part (31) and the flow path cover (4), and a gap between the rising part (32) and the flow path cover (4).
