A package-type compressor includes a body unit, a controller, a casing, a first cooling air inlet, a second cooling air inlet, a cooling air outlet, a fan duct, a cooling fan, an air cooling type heat exchanger, a machine chamber, and a cooling duct. The cooling duct is provided below the fan duct, the cooling duct causing the cooling air taken in at the second cooling air inlet to flow along the controller toward the suction port of the fan duct. A vertical projection plane of the cooling fan overlaps the machine chamber and the cooling duct.

Air compressor 10 for a vehicle, including at least one cooling duct 30 arranged to convey air from outside of the compressor 10, alongside a sealable chamber 28 containing a motor 22, alongside a cylinder 12, and through a cylinder head 18 to emit from at least one exhaust 32 spaced from an air inlet 20, and a fan 34 operable to impel air through the, or each, cooling duct 30. Alternatively or additionally, the compressor 10 includes a sensor 56 arranged to sense a critical parameter of the compressor 10, and a controller in communication with the motor 22 and the sensor 56, the controller configured to control operation of the motor 22 to adjust a rotational speed of a shaft 24 responsive to receiving a sensed value from the sensor 56.

An air compressor contains a piston actuated by a motor to move in a cylinder. The piston includes an air stop sheet mounted on a top support plate thereof. The air stop sheet includes a bending section having a positioning zone and an acting zone located opposite to the positioning zone and configured to cover an air channel of the piston. The bending section is a boundary axis of the acting area and the positioning zone of the air stop sheet so that a top of the air stop sheet facing the cylinder forms an obtuse angle less than 180 degrees, and a back surface of the acting zone of the air stop sheet backing a top of the cylinder turns on relative to a plane of a top of the top support plate at an open angle θ, thus producing an air flowing space.

Example implementations involve a system involving a portable container package that includes a first air compressor and a second air compressor disposed therein in a side-by-side configuration and oriented in opposing directions. The first air compressor and the second air compressor each have a corresponding electric motor, and a split cooler disposed on opposite ends of the portable container package. Air vents are supplied on opposite sides of the portable container package so that air flow can be received through the air vents to a corresponding air compressor.

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.

An aeration cabinet is provided. The aeration cabinet secures a compressor within. The aeration cabinet includes a bottom portion operable to support the aeration cabinet in an upright position when resting on a surface. The bottom portion may include a base plate. The present invention further includes a front wall, a rear wall, a first side wall and a second side wall extending vertically from the horizontal base plate. A lid covers an opening formed along an upper edge of the front wall, the rear wall, the first side wall and the second side wall. A plurality of first vent slots are formed through the aeration cabinet where the front wall and the base plate meet. A plurality of second vent slots are formed through the aeration cabinet where the lid and the rear wall meet.

An air compressor includes an air storage container, a cylinder fitted with a piston body and a main frame for mounting a motor. The cylinder and the main frame are integrally formed of plastic. The air storage container is detachably mounted to the cylinder. The main frame is provided with though holes for guiding the air flow, generated by a cooling fan, to flow through the main frame. The main frame is formed with two lateral walls and a bottom wall to form a U-shaped wind collecting shell. The second portion of the main frame is held by multiple radial braces, which facilitates the air flow being introduced through the main frame for rapidly dissipating the heat generated from the reciprocating motion of the piston body, so that the operational security can be increased. The non-metal air compressor may lead to a reduction of the manufacturing cost and the weight.

A multi-stage gas compression system useful at the production site and at central collection points, having an energy efficient and effective intercooler system. The system includes a reciprocating compressor having a plurality of compressor valves and cylinders configured in series to provide staged compression to the natural gas. Coupled with the compressor are an inlet port for receiving natural gas to be compressed, and an outlet port for delivering compressed fluid from the compressor to a discharge line, to the transmission pipeline or storage. Facilitating transmission and intercooling of the natural gas between cylinders are a plurality of pipes, each pipe in close proximity with an intercooler. The rate of cooling of the intercooler is determined by a control system coupled therewith, including a temperature sensor positioned within pipe proximal to the intercooler, and means to compare the temperature measured by the temperature sensor and an optimal temperature or temperature range, and determine appropriate levels of cooling provided by the intercooler.

A compressor may include a compressor shell, a motor, a compression mechanism, and an assembly that houses an electronic component. The electronic component may control operation of the compressor and/or diagnose compressor faults. The assembly may include a shell, an electronic component, a fan, and an airflow deflector. The shell member may define an enclosure having an internal cavity. The fan and the electronic component may be disposed within the internal cavity. The airflow deflector may include a base portion, a first leg, and a second leg. The first and second legs may be spaced apart from each other and extend from the base portion. The fan may force air against the base portion. A first portion of the air may flow from the base portion along the first leg. A second portion of the air may flow from the base portion along the second leg.

A compressor may include a shell, a first scroll, and a second scroll. The shell may include a first inlet, a second inlet, and an outlet. The first scroll may include a first end plate and a first spiral wrap. The second scroll may include a second end plate and a second spiral wrap, the first and second spiral wraps cooperating to define a series of moving compression pockets therebetween. The moving compression pockets decrease in volume as the moving compression pockets move from a radially outer position to a radially inner position. The moving compression pockets may receive working fluid from the first inlet at the radially outer position and provide working fluid to the outlet at the radially inner position. The second end plate may include a fluid cavity receiving working fluid from the second inlet and fluidly isolated from working fluid within the moving compression pockets.
