A semiconductor device according to the present invention has a semiconductor module; a cooling unit, the semiconductor modulebeing joined to an upper surface of the cooling unit, and a pipefor circulating a refrigerant being fixed to a side surfaceof the cooling unit; and a resin mold layerthat covers outer peripheries of the semiconductor moduleand the cooling unit. Further, a protruding portionthat protrudes from the side surfaceof the cooling unitand surrounds the pipeis provided on the side surfaceof the cooling unit

Semiconductor device and method for manufacturing semiconductor device

An EGR device includes a first cooling passage that introduces a flowing medium discharged from an engine into a main radiator so that the flowing medium is cooled therein, and then returns the flowing medium to the engine, and a second cooling passage that introduces a part of the flowing medium cooled in the first cooling passage to a sub-radiator so that the flowing medium is further cooled therein. The second cooling passage introduces the flowing medium to an EGR cooler to return the flowing medium, which is discharged from the EGR cooler, to the engine.

EGR device

In a warm-up system that pre-warms up of an engine (E) by transferring heat from a heat source to an engine cooling water circulation circuit () of a vehicle, a residential hot water circuit () that uses a household heat source is provided as the heat source, and a one-touch connector () is provided in the engine cooling water circulation circuit () and the residential hot water circuit (). The one-touch connector () connects the two circuits () prior to start-up of the engine (E) such that heat is transferred to the engine cooling water circulation circuit (), and disconnects the two circuits () following heat transfer in preparation for start-up of the engine (E).
