摘要： A housing member includes a case member and a cover member having an insertion portion inserted into a seal groove. The case member and the cover member assembled together provide a housing space for housing a protective component inside. A housing space side inner groove surface of a peripheral wall portion and an external space side inner groove surface of the peripheral wall portion extend along an insertion direction of the insertion portion into the seal groove. A first distance between the external space side peripheral surface and the external space side inner groove surface opposite to the external space side peripheral surface is larger than a second distance between a housing space side peripheral surface extending along the insertion direction on the housing space side of the insertion portion and the housing space side inner groove surface opposite to the housing space side peripheral surface.

摘要： To significantly improve a heat dissipation property of an axial gap rotary electric machine within a size necessary for configuring a motor. In an axial gap rotary electric machine comprising a stator and a rotor in an axial direction, the stator has a plurality of stator cores arranged in a circumferential direction and coils wound around the stator cores, and a heat pipe obtained by filling an inside of a metal hollow pipe with a refrigerant is arranged in a gap between adjacent coils formed in an outer diameter portion of the stator in a radial direction and a housing with a necessary insulation distance between the coils and the heat pipe. The heat pipe extends in a direction of a rotation axis and an opposite output side, and is in contact with a heat dissipating fin outside an end bracket on the opposite output side.

摘要： A refrigerating machine having a detachable Hall element is provided with a cold heat exchange mechanism. The cold-heat exchange mechanism is driven by a driving assembly to generate a low temperature cooling zone at one end of the cold heat exchange mechanism. The driving assembly is composed of at least one rotor and a stator. After the power is input, the rotor can rotate a shaft to drive the cold-heat exchange mechanism to work. The driving assembly further has at least one Hall element and a circuit board on which the Hall element is mounted. Therefore, when the Hall element is damaged, the circuit board can be easily removed for replacement or repair.

摘要： The invention in part, is a heat removal system or apparatus providing a method of mounting and electrically connecting heat dissipating electrical devices, preferably in a radial geometry while achieving good surface-to-surface clamping force, in liquid and or air cooled variants. A variation of the invention can provide arc safety for high power density applications. In specific embodiments, the invention also provides low inductance as a result of minimal loop area while also providing high voltage isolation between devices. The N-sided geometry and effective clamping methodology offer low mass and volume. A variation of the invention also provides a signal interface for driving power electronics devices. A unique cylindrical electrical device package with terminals can support capacitor, inductor and transformer integration in a common package. The various elements of the invention can be combined together to minimize size and weight, while addressing high voltage, noise and thermal management.
