A rotary electrical machine includes a housing which includes a flow passage portion in which a refrigerant flow passage through which a refrigerant flows is formed and which houses a rotor and a stator. The refrigerant flow passage includes a first flow passage of which a length from the inlet to the outlet in the circumferential direction is a predetermined length, and a second flow passage of which a length from the inlet to the outlet in the circumferential direction is shorter than that of the first flow passage. The second flow passage is provided with a partition wall portion between the inner peripheral wall and the outer peripheral wall in the radial direction. A slit penetrating the partition wall portion in the circumferential direction is formed in the partition wall portion. A width of the slit is smaller than a width of the first flow passage.

A rotating electric machinehaving a rotor, a stator, and a coilincluding a coil conductorwound around teethprovided on at least one of the rotorand the statorincludes a spacer sectionconfigured to extend along a slot S formed between the teethand to be inserted between turns of the coil conductorto define a gap G between the turns, and a cooling medium supply sectionconfigured to distribute a cooling medium in the gap G. A notched sectioncut out in such a manner that a widthwise dimension of the spacer sectionis relatively short is provided in a middle of an extension of the spacer section

An oil separator for separating oil from exhausted gas containing refrigerant gas and fine particles of oil incorporated in the refrigerant gas including grooved plates each formed with a multiplicity of grooves on opposite surfaces to allow the exhausted gas to flow in a direction substantially at right angles to the grooves, whereby the fine particles of oil can be trapped by the grooved plates. The oil separator can achieve increased oil separation efficiency.

A heat pipe is provided with a multiplicity of longitudinal deep grooves and ridges formed in the inner peripheral surface thereof. A plurality of shallow grooves are formed by a plastic work in the top surfaces of the longitudinal ridges separating the deep grooves. Parts of burrs formed as a result of the plastic work for forming the shallow grooves are extended over the deep groove so as to form bridges connecting adjacent ridges over the deep grooves.

Method of producing heat pipe

An automobile air conditioner has a refrigeration cycle composed of a compressor, condenser, liquid tank, orifice means and an evaporator, as well as mechanical parts such as a radiator and radiator fan associated with the condenser and a blower combined with the evaporator. The compressor is operatively connected to the automobile engine through a connecting means so as to be driven by the engine selectively in accordance with the temperature in the passenger's compartment. According to the invention, the compressor is driven when the automobile is being braked, even if the temperature in the compartment is lower than a set temperature, to make an efficient use of the kinetic energy possessed by the mass of the automobile. The cold energy generated during braking is suitably stored and is released into the passenger's compartment as desired.
