Abstract: An air conditioning system includes an air conditioning unit and an electricity generating unit. The air conditioning unit includes an expansion valve, an evaporator, a compressor and a condenser that cooperate to form a first coolant circulating loop for circulation of a first coolant. The electricity generating unit includes a heat radiator disposed adjacent to the evaporator, a heat absorber coupled to the heat radiator and disposed adjacent to the condenser, a turbine coupled between the heat radiator and the heat absorber, and an electricity generator coupled to the turbine. The heat radiator, the heat absorber and the turbine cooperate to form a second coolant circulating loop for circulation of a second coolant. The electricity generator converts mechanical energy from the turbine into electricity.

Abstract: An electric motor includes a rotor unit disposed rotatably in a motor housing. The rotor unit includes a rotor shaft rotatable relative to the motor housing about a central axis of the motor housing, a heat conductive seat mounted with a magnet member and in sleeved relationship to an intermediate portion of the rotor shaft, and angularly spaced apart heat pipes extending through an end portion of the rotor shaft thicker than the intermediate portion and into the seat. Each heat pipe has an end portion disposed outward of the rotor shaft, and extending into and in thermal contact with a heat conductive impeller connected to the second end portion of the rotor shaft to co-rotate with the rotor shaft and covered by an outer shell cap. A stator unit is mounted fixedly in and is in thermal contact with the motor housing, and is disposed around the rotor unit.

Abstract: A motor assembly includes a housing, a revolving shaft revolvably mounted in the housing, a magnet mounting portion surrounding and rotatable with the revolving shaft, a magnet disposed on the magnet mounting portion, a magnetically inducible core having a plurality of stator poles spaced apart from rotor magnetic poles of the magnet, and a plurality of stator windings wound on the stator poles, respectively. The stator windings are spaced apart from end walls of the housing by axial intervals. A thermally conductive bridging member is disposed to span the axial intervals to conduct heat emanating from the stator windings to the end walls so as to dissipate heat out of the housing.

Abstract: A motor device includes a motor body and a set of heat-conducting pipes. The motor body includes a motor casing that defines a chamber, a stator that is disposed in the chamber, and a rotor that is rotatably disposed in the chamber. Each of the heat-conducting pipes has a heat-absorbing end that extends into the motor body, and a heat-dissipating end that is opposite to the heat-absorbing end and that extends outwardly of the motor body.

Abstract: A closed-type motor includes a casing defining a chamber, a stator fixed in the chamber, a rotor mounted in the chamber and rotatable relative to the stator, and a cooling tube having inlet and outlet ends, and an intermediate portion interconnecting the inlet and outlet ends and located within the chamber. The inlet end extends out of the casing, and is adapted for entry of a cooling fluid. The outlet end extends out of the casing, and is adapted for exit of the cooling fluid that flows through the intermediate portion.
