Electric power source

The electric power source contains a plurality of batteries stacked in two or more tiers in a battery case which is provided with an intermediary duct placed between the first sub holder case and second sub holder case. A first outer duct is outside the first sub holder case and a second outer duct is outside the second sub holder case. The power source is so designed that cooling air is blown to the intermediary duct, the holder case and the outer duct, thus cooling the batteries in the holder case. Further, the power source has a partition disposed inside the intermediary duct, with the first intermediary sub duct being connected to the first sub holder case and the second intermediary duct being connected to the second sub holder case.

Lamination stack cooling path

According to one embodiment, the present invention provides a motor having a stator core disposed in a motor frame. The stator core is formed of a plurality of substantially identical laminations. Each lamination of the stator core comprises at least one recessed section, which, in cooperation with the frame, defines an incremental segment of closed passageway for routing a fluid along a perimetric surface of the stator core. Accordingly, the closed passageway provides a mechanism by which the outer regions of the stator core may be more effectively cooled. Furthermore, the laminations of the stator core may be oriented at varied orientations with respect to one another to form a labyrinthine path along the surface of the stator core through which coolant is routed.

Semiconductor device and cooler thereof

A semiconductor device exhibits low pressure loss and is capable of cooling a plurality of power semiconductor chips evenly. This semiconductor device includes a semiconductor module and a cooler for cooling a power semiconductor element mounted in the semiconductor module. A cooling unit of the cooler has a first header part that has a first bottom surface disposed between a coolant inlet and an end portion of a first substrate on the coolant outlet side and inclined toward a bottom plane of cooling fins so that a coolant supplied from the coolant inlet flows toward the cooling fins; and a second header part that has a second bottom surface inclined from an end portion of the bottom plane of the cooling fins on the coolant outlet side so that the coolant discharged from the cooling fins flows to the coolant outlet.

Method for bending metal material, bending machine, bending-equipment line, and bent product thereof

A method of push-through bending processing for a metal material, comprising, while sequentially or continuously extruding a material to be processed from the upstream side, carrying out bending processing thereof on the downstream side, wherein the metal material is clamped by means of mobile roller dies and under controlling of the position and / or moving speed of the mobile roller dies, heated at a temperature range permitting local plastic deformation and permitting quench hardening by means of heating means and cooling means disposed on the periphery of the metal material, followed by application of a bending moment and quenching. Further, there are provided a relevant bending processing apparatus and bending processing equipment line. Even in the event of processing to achieve continuous bending involving two-dimensionally different bending directions, or continuous bending involving three-dimensionally different bending directions, of the metal material, and even in the event of requirement of bending processing for a metal material with greater strength, a metal material with high shape fixability and uniform hardness distribution can be obtained efficiently at low cost. Accordingly, wide application thereof can be found as an increasingly sophisticated automobile part bending processing technology.
