Abstract: A trench region 14 is formed in a memory cell P-type well 13. Two NAND-type memory cell units ND1 and ND2 are respectively formed along both side wall portions of this trench region 14.

Abstract: A compound type heat exchanger has a core part including a plurality of heat exchanging tubes and fins juxtaposed and alternately stacked. Header pipes are connected to the heat exchanging tubes at both ends of the heat exchanging tubes.

At the boundary of the pseudo heat exchanging passage member, the core part is divided into two parts, defining an oil cooler unit and a condenser unit. Owing to the provision of the pseudo heat exchanging passage member in the core part, heat conduction from the oil cooler unit to the condenser unit can be suppressed.

At both ends of the lamination in the longitudinal direction of the pipes, they are connected with header pipes. A pseudo heat exchanging passage member having a substantially Z-shaped section is arranged in place of a specified heat exchanging tube of the heat exchanging tubes and a fin adjoining the specified heat exchanging tube.

At the boundary of the pseudo heat exchanging passage member, the core part is divided into two parts in the laminating direction, defining an oil cooler unit on one hand and a condenser unit on the other hand. Owing to the provision of the pseudo heat exchanging passage member in the core part, heat conduction from the oil cooler unit to the condenser unit can be suppressed.
