An electric machine has a housing which has an interior space and an interior wall extending about the interior space, and a stator assembly disposed within the interior space and attached to the interior wall. The electric machine includes a rotor within the interior space and located radially inward from the stator. The rotor and stator define a gap there between and cooperate to produce flux. The rotor comprises a hollow cylindrical member having an interior region, an interior wall extending about the interior region and an exterior surface. The rotor includes magnets attached to the exterior surface and a rotor shaft support structure disposed within the interior region of the hollow cylindrical member and attached to the interior wall of the hollow cylindrical member. A rotor shaft is attached to the rotor shaft support structure. The electric machine further comprises bearings to locate and support the rotor shaft relative to the housing.

A method for heating a fluid using a heating tower. The method includes the steps of drawing an air stream into the heating tower through an inlet and passing the air stream over a fill medium. The method for heating a fluid also includes passing a fluid of the fill medium along with discharging the air stream from the heating tower through an outlet. The method further includes isolating the inlet air stream from the outlet air stream.

The invention concerns a method and a system for controlling the circulation of water films on the exchange walls of an exchange surface of a cooling tower. It consists in combining a tank (2) and a dispensing lip (3) which ensure that the film has a specific thickness and that it adheres to the exchange wall right from the moment it starts to flow and repeatedly so on each exchange wall. The exchange walls between air and water are sloping on the horizontal at a small angle, thereby ensuring that the water flows by force of gravity and, at the same time, limiting the speed increase on the plate to avoid the droplets from being pulled away by the air stream.

A cooling tower is constructed having a plurality of fill sheets (90) within the tower, water sprays including a plurality of spray nozzles (48) and supply pipes (42) for delivering water to the fill sheets (90), an exposed area for air to enter between the fill sheets (90). A plurality of passageways (70) extends from the perimeter of the cooling tower to the center so as to deliver air from outside said cooling tower to the centrally located portions of the exposed areas of the fill sheets (90). The passageways (70) include areas beneath conduits (20) for delivering water to said water sprays, said conduits (20) forming upper walls (30) together with curtain walls (86) forming partial sides for said passageways (70).

摘要:
A method and apparatus for removing and replacing an integral-motor fan from below. A support assembly has support struts fixed to a mounting ring. Mounting ring is configured to be fixed to the fan head, holding the fan in place, and support struts are configured to rest on mounting bolts fixed to a fan shroud. To mount a fan in place from below, the fan is fixed to the mounting ring of the support assembly, and the support assembly and attached fan are lifted into the fan shroud. The support assembly is rotated until the struts align with the support bolts in the fan shroud. The support assembly is then lowered until the struts come to rest on the support bolts. A power cable with a length sufficient to lower the fan support assembly out of the fan shroud prior to disconnecting the power cable from the fan body.
摘要:
An integrated fan drive system for a cooling tower comprising a high-torque, low speed permanent magnet motor having a rotatable shaft, a fan comprising a hub that is directly connected to the rotatable shaft and a plurality of fan blades that are attached to the hub, and a variable frequency drive device in electrical signal communication with the permanent magnet motor to control the rotational speed of the permanent magnet motor. The high-torque, permanent magnet motor comprises no more than two bearings in operative association with the shaft. The variable frequency drive device has a variable frequency controller that has an input for receiving AC power and an output for providing electrical signals that control the operational speed of high-torque, permanent magnet motor. The variable frequency drive device also includes a user interface in electronic data signal communication with the variable frequency controller to allow a user to input motor speed control data.
摘要:
A cooling tower apparatus (10) that extends along a vertical axis is provided. The cooling tower (10) includes a first housing structure (20) having an inlet and a first outlet (34) located a first position along the vertical axis, wherein the housing structure includes a base (22) and opposing side walls (24) that extend along the vertical axis away from the base (22). The tower (10) also includes a heat exchanger (21) disposed in the housing structure (20), wherein the heat exchanger (21) is positioned adjacent the first outlet (34) and extends at least partially all the way across the first outlet (34). Finally the hybrid tower employs an air current generator (30) positioned in a plane normal to the vertical axis and oriented to direct an air stream toward the base (22) and through the heat exchanger (21) and the first outlet (34).
