Separable outer enclosure for turbo blower

An outer enclosure configured to house a turbo blower, the outer enclosure comprising:

• a housing forming an exterior of the outer enclosure;
• an outside air inflow chamber which is a space partitioned in a first side of the housing and which communicates with outside air through an outside air inlet;
• an inverter chamber which is a space partitioned in a second side of the housing;
• a motor chamber which is a space partitioned in an upper portion of a space positioned between the inverter chamber and the outside air inflow chamber, and in which the turbo blower including an intake nozzle communicating with the outside air inflow chamber is positioned, and a first refrigerant discharge port is positioned on a third side of the housing;
• 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;
• a back plate, a front plate, an upper plate, a lower plate, and a plurality of side plates, which form the housing;
• a first partition wall positioned adjacent to the back plate inside the housing, partitioning a space for the outside air inflow chamber;
• a second partition wall positioned adjacent to the front plate inside the housing, partitioning a space for the inverter chamber in which an inverter is disposed;
• a third partition wall positioned between the first partition wall and the second partition wall to vertically partition the spaces of the motor chamber and the refrigerant inflow chamber, respectively;
• an outside air vent positioned on the first partition wall to allow the outside air inflow chamber to be in communication with the intake nozzle of the turbo blower;
• a first refrigerant vent positioned on the second partition wall to allow the refrigerant inflow chamber and the inverter chamber to be in communication with each other;
• a second refrigerant vent positioned on the second partition wall to allow the inverter chamber and the motor chamber to be in communication with each other;
• and
• a third refrigerant vent positioned on the third partition wall to allow the refrigerant inflow chamber and the motor chamber to be in communication with each other,
• wherein the outside air is sucked into the intake nozzle of the turbo blower through the outside air vent of the outside air inflow chamber by the operation of the turbo blower;
• some of refrigerant flowing into the refrigerant inflow chamber flows into the motor chamber through the third refrigerant vent to cool a motor of the motor chamber;
• and
• the remainder of the refrigerant that flows into the refrigerant inflow chamber flows into the inverter chamber through the first refrigerant vent to cool the motor chamber while flowing upwards, and flows into the motor chamber through the second refrigerant vent to further cool a motor of the turbo blower.
