Abstract:
An electrical power conversion device is provided which includes a stack of semiconductor modules and a plurality of cooling pipes. Each of the cooling pipes includes a first and a second outer shell plate which are electrically conductive. Each of the outer shell plates includes a flow-path defining portion which defines a coolant flow path between the outer shell plates and a flow-path outer periphery forming a circumference of the flow-path defining portion. The flow-path outer periphery of at least one of the outer shell plates has formed thereon an outer shell protrusion which is laid to overlap power terminals or control terminals extending from the semiconductor module to cancel a magnetic flux, as developed around the power terminals or the control terminals, thereby decreasing the inductance of the power terminals or the control terminals.

Claim (Index 1):
An electrical power conversion apparatus comprising:\n a semiconductor module which includes a module body in which a semiconductor device is installed, a plurality of power terminals extending from the module body, and a plurality of control terminals extending from the module body, the module body having major surfaces; and a first and a second cooling pipe which are stacked on each other through the semiconductor module and hold the major surfaces of the module body therebetween, wherein the power terminals extend from the module body in a first height-wise direction that is one of height-wise directions perpendicular to a stacking direction in which the first and second cooling pipes and the semiconductor module are stacked, wherein the control terminals extend from the module body in a second height-wise direction that is one of the height-wise directions, wherein each of the first and second cooling pipes includes a first and second outer shell plate which are electrically conductive and face each other in the stacking direction, the first and second outer shell plates forming a coolant flow path therebetween, wherein each of the first and second outer shell plates includes a flow-path defining portion which defines the coolant flow path and a flow-path outer periphery which forms an outer circumference of the flow-path defining portion, as viewed in the stacking direction, wherein the flow-path outer periphery of at least one of the first and second outer shell plates includes an outer shell protrusion located on one of sides of the flow-path defining portion in the height-wise directions, wherein the outer shell protrusion has a protruding dimension that is a distance between an outer edge of the outer shell protrusion and an outer edge of the flow-path defining portion is selected to be greater than a protruding dimension of a circumferential side portion of the flow-path outer periphery which protrudes outwardly from the flow-path defining portion in a lateral direction perpendicular to the height-wise directions and the stacking direction, and wherein the outer shell protrusion is laid to overlap the power terminals or the control terminals in the stacking direction.
