The baseboard includes a first opening such that a portion of the tab of the ejector is configured to directly contact the electronic component therethrough.

A fluid heat exchanger with pump, adapted to drive a fluid for heat transfer, comprises a heat conduction unit, a diversion unit, and a housing unit. The heat conduction unit includes a heat conductor. The diversion unit includes a cover and a diversion plate. A cooling chamber is defined by the cover and the heat conductor. The cover is provided with a fluid stopper. The diversion plate is disposed in the cooling chamber, and one end of the diversion plate abuts against the fluid stopper, so that the cooling chamber is divided into an upper passage and a lower passage. The housing unit includes a housing and a pump module. The fluid in the housing is driven by the pump module to flow through the upper passage to the lower passage, and then the fluid returns to the housing to carry the heat from the heat conductor.

A turbo compressor comprises a rotary shaft including a rotor; a first impeller coupled to one side of the rotary shaft, a thrust bearing runner coupled between the first impeller and the rotary shaft, an impeller sleeve compressed and coupled between the first impeller and the thrust bearing runner, a second impeller coupled to the other side of the rotary shaft, and a tie rod passing through the first impeller and a thrust bearing and fastened to the rotary shaft.

Provided is an outer enclosure for a turbo blower in which a turbo blower is installed, which includes a housing forming an exterior of the outer enclosure, an outside air inflow chamber which is a space partitioned in one side inside the housing and which communicates with the outside through an outside air inlet, an inverter chamber which is a space partitioned in the other side inside the housing, a motor chamber which is a space partitioned in an upper portion of a space positioned between an inverter chamber and the outside air inflow chamber, and in which a turbo blower including an intake nozzle communicating with the outside air inflow chamber is positioned, and a first refrigerant discharge port is positioned on one side, a refrigerant inflow chamber which is a space in a lower portion of the motor chamber and which communicates with the outside through a refrigerant inlet, in which the upper and lower portions of the inverter chamber are in communication with the motor chamber and the refrigerant inflow chamber, respectively, and the refrigerant inflow chamber is communication with the motor chamber.

A portable blower assembly includes a cylinder that has an exhaust port integrated into the cylinder. A handle extends around the cylinder and the handle can be gripped by a user for directing the exhaust port toward a vehicle. A blower is rotatably integrated into the cylinder to urge air outwardly through the exhaust port thereby facilitating the air to be directed onto the vehicle for drying the vehicle when the blower is turned on. A heater is integrated into the cylinder such that the heater is in thermal communication with an interior of the cylinder. The heater is positioned between the blower and the exhaust port to heat the air is blown by the blower for enhancing drying the vehicle.

A heat exchanger arrangement includes a housing in which an air inlet opening is arranged on the circumference, a cover that covers the housing on an upper side and in which an air outlet opening is arranged, a reverse-operated radial fan being arranged inside the housing in such a way that it can generate an air flow between the air inlet opening and the air outlet opening, which air flow is directed radially inward with respect to the axis of rotation of the radial fan and which flows through at least one air heat exchanger arranged in the housing.

A centrifugal compressor includes a motor cooling passage through which cooling fluid for cooling an electric motor flows, an air passage through which cooling air for cooling a first air bearing and a second air bearing is supplied to each of the first air bearing and the second air bearing, and a heat exchanger cooling the cooling air. The motor cooling passage includes a plurality of cooling axial passages having a first cooling axial passage through which the cooling fluid is supplied to the heat exchanger and a second cooling axial passage through which the cooling fluid is discharged from the heat exchanger. The heat exchanger has a first port communicating with the first cooling axial passage, a second port communicating with the second cooling axial passage, and a third port communicating with an air axial passage extending in an axial direction of a rotary shaft.

A blower device and a vehicular air-conditioning device including a chamber for air flow so as to cool a motor, whereby water drops are prevented from reaching the motor with higher reliability. Included is a casing having an air intake port, an air discharge port, and a discharge flow path portion communicating between the air intake port and the air discharge port; a scroll fan provided in the casing to take in the air from the air intake port and generate an air flow to the air discharge port through the discharge flow path portion; a motor rotationally driving the scroll fan; and a motor cooling unit cooling the motor. The motor cooling unit includes a chamber for partial air flow from the discharge flow path portion and a cooling duct having an opening portion which opens into the chamber at one end and supplying air to the motor.
