361715, 36167954, 361708, 361721, 361704, 165 803, 16510433, 165185

Abstract:

A multi-hybrid module includes a plurality of hybrid assemblies that are perpendicularly mounted with respect to a plane of a circuit board. The hybrid assemblies are mounted on opposing sides of a heat sink. The heat sink has a first column disposed at a first end, a second column disposed at a second opposing end, and a generally flat center wall extending between the first column and the second column to which the hybrid assemblies are mounted. During operation the hybrid assemblies are mounted on edge perpendicular with respect to the circuit board to minimize an area profile of the multi-hybrid module on the circuit board.

International Classification:

H02K 9/00

US Classification:

310 52

Abstract:

A motor controller for use in an environment at a high maximum environmental temperature comprises an insulated chassis, a high-temperature capable electronic component, a low-temperature capable electronic component, and a heat pump. The high-temperature capable electronic component is rated for temperatures higher than the environmental temperature, whereas the low-temperature capable electronic component is rated for temperatures lower than the maximum environmental temperature. The insulated chassis has a finned surface to which the high-temperature capable electronic component is mounted. The low-temperature capable electronic component is attached to or integrated into a printed wiring board supported inside the insulated chassis by the thermally conductive posts. The heat pump is configured to draw heat from the low-temperature capable electronic component through the thermally conductive posts and a thermal spreader abutting the heat pump, and to expel heat into the finned surface of the insulating chassis.

International Classification:

F28D 1/047
F01D 25/12

Abstract:

A heat exchanger system is disclosed herein that extends between a first component and a second component. The heat exchanger system includes a hot flow path configured to convey hot fluid between the first component and the second component, a cool flow path configured to convey cool fluid, and a heat exchanger located between the first component and the second component along the hot flow path and the cool flow path. The heat exchanger includes at least one curve to accommodate the hot flow path and is configured to reduce the temperature of the hot fluid by allowing the transfer of thermal energy from the hot fluid to the cool fluid.

International Classification:

F28D 1/047
F28D 1/053

Abstract:

A heat exchanger includes a first fluid manifold extending along a first fluid axis from a first fluid inlet to a first fluid outlet. The first fluid manifold includes a first fluid inlet header, a first fluid outlet header, and a nested helical core section. The first fluid inlet header is disposed to fork the first fluid inlet into a plurality of first fluid branches distributed circumferentially and radially about the first fluid axis. The first fluid outlet header is disposed to combine the plurality of first fluid branches into the first fluid outlet. The nested helical core section fluidly connects the first fluid inlet header to the first fluid outlet header via a plurality of nested helical tubes, and includes radially inner and outer groups of circumferentially distributed helical tubes.

Abstract:

A heat exchanger includes a first fluid manifold extending along a first fluid axis from a first fluid inlet to a first fluid outlet. The first fluid manifold comprises a inlet header, a outlet header, and a multi-helical core section. The inlet header is disposed to fork the first fluid inlet into a plurality of first fluid branches distributed laterally across a plane normal to the first fluid axis. The outlet header is disposed to combine the plurality of first fluid branches into the first fluid outlet. The multi-helical core section fluidly connects the inlet header to the outlet header via a plurality of laterally distributed helical tubes, each helical tube corresponding to one of the plurality of first fluid branches and oriented parallel to all others of the plurality of helical tubes at each axial location along the first fluid axis.
