Disclosed herein is an apparatus for cooling an inverter of a vehicle which receives power supplied from a vehicle battery and controls the rotation speed of a motor. The apparatus includes an inverter housing configured to support the inverter, and a heat dissipation unit provided at a predetermined position in the inverter housing and configured to come into contact with an outer circumferential surface of the capacitor so that heat of the capacitor is transferred to the inverter housing.

A transverse flux reciprocating motor and a reciprocating compressor having a transverse flux reciprocating motor are provided. The transverse flux reciprocating motor may include a stator wound with a magnet coil, a mover inserted into the stator and coupled with a magnet having opposite magnetic poles in an orthogonal direction with respect to a magnetic flux generated by the magnet coil, and a magnetic resonance spring that allows the mover to perform a resonance motion with respect to the stator using a force trying to move toward a side with low magnetic resistance between the stator and the mover, whereby the transverse flux reciprocating motor and the reciprocating compressor having a transverse flux reciprocating motor may be reduced in size and weight and obtain high efficiency.

A crankcase heating control system for a heat pump system includes a data receiving module and a power control module. The data receiving module receives data indicative of a temperature of a compressor of the heat pump system, data indicative of an ambient temperature, and data indicative of a current date and a current time. The power control module selectively applies power to a heater of a crankcase of the compressor and selectively disables the heater based on the temperature of the compressor, the ambient temperature, the current date, and the current time.

A reciprocating compressor is provided that may include a shell including a vibration absorbing member formed to be wound around an outer circumferential surface or an inner circumferential surface or stacked thereon, so that compressor vibration may be attenuated by frictional contact between the shell and the vibration absorbing member or between layers of the vibration absorbing member. Also a noise insulating layer may be formed between the shell and the vibration absorbing member or between the layers of the vibration absorbing member, so that a magnitude of noise may be reduced as vibration noise passes through the noise insulating layer, whereby vibration noise of the compressor, such as noise of a high frequency band, may be further attenuated by fine vibration.

A compressor and an air conditioner having the compressor, and a protective cover of a connecting terminal of the compressor is installed while spaced apart from a barrier of the connecting terminal. The protective cover is additionally provided with a noise preventing member. Vibration generated from the compressor is delivered to the protective cover via the barrier, but as the protective cover is provided to be spaced apart from the barrier, the vibration is delivered to the barrier through the noise preventing member. Thus, regardless of the state of vibration of the compressor, noise being generated by the protective cover is minimized.

A compressor may include a compression mechanism and a shell assembly. The shell assembly may include first and second snap rings, a body, and first and second caps cooperating with the body to enclose the compression mechanism therein. The body may include first and second ends and an inner surface extending between both ends. The first cap may be received within the first end and may include a first side wall having a first groove. The second cap may be received within the second end and may include a second side wall having a second groove. The first snap ring may be disposed within the first groove and may engage the first end to restrict removal of the first cap from the body. The second snap ring may be disposed within the second groove and may engage the second end to restrict removal of the second cap from the body.

The present invention discloses an energy-saving one-dimensional compressor, comprising an air compressor, a fixing rod, a bearing plate, a condensing tube and a driving device. The air compressor comprises an inner shell and an outer shell; the inner shell comprises an upper pressing plate and a cylindrical plate; a top of the cylindrical plate is fixed under the upper pressing plate; an air inlet is formed at an upper part of the outer shell; part of a bottom of the outer shell protrudes downwards to form a cylindrical plate slot corresponding to the cylindrical plate; and the cylindrical plate can move up and down in the cylindrical plate slot. An air outlet is also formed at the bottom of the outer shell. The present invention has the beneficial effects of simple structure and high energy utilization rate.

The present invention relates to a suspension disposed between a compression unit and the hermetic housing of hermetic reciprocating compressors for mobile application, such as, for example, application in automotive vehicles and similar, and to the method of assembly of the components that constitute the referred suspension. According to the present invention, it is disclosed a suspension for hermetic reciprocating compressor for mobile application capable of reducing the effects of an eventual and involuntary sudden movement of the compression unit and also of minimizing the transfer of vibrations and noises deriving from the environment outside the hermetic housing to the compression unit.

The present invention belongs to the technological field of structural components of hermetically sealed compressors. Problem to be resolved: Currently, reciprocating compressors include protective plates which, welded to the outer side of their hermetically sealed carcasses, have small functional dimensions, which ultimately limit the size of electrical or electronic circuits to be fixed on the said protective plates. Problem Resolution: It is disclosed a reciprocating compressor, whose protective plate is conformed by at least one first plate segment and at least one second plate segment, wherein firstly it occurs the fixation of the first plate segment on the base of the hermetically sealed housing of the reciprocating compressor, subsequently, the lid is fixed on the base in order to form the hermetically sealed housing and, finally, the second plate segment is fixed on the first plate segment.

A pump unit includes a drive motor (14) and a first housing (2), in which a control electronics unit (18) is arranged for operating the drive motor (14). An operating unit (20) having at least one display or operating element (26, 28, 30) can be detachably connected to the first housing in at least two different positions.
