The air fan with ice compartment is a thermal transfer device. The air fan with ice compartment is an enclosed structure that forces an air flow over a thermally treated mass, such as ice pack, and discharges the processed air flow into the atmosphere. The air fan with ice compartment comprises a base, a fan assembly, a fan control, an over chamber, and a lid. The fan assembly mounts on the base. The over chamber mounts over the fan assembly and the base. The lid and the fan control mount on the over chamber. The fan control controls the operation of the fan assembly. The fan assembly forces the air flow through the space enclosed by the over chamber and the base.

In an aspect, a clutched device is provided, and includes an input member, an output member, a one-way clutch that can operatively connect the input member to the output member, and a motor including a stator and a rotor. The rotor is connected for rotation with a portion of the one-way clutch. The stator is operable to apply a first magnetic driving force to cause movement of the portion of the one-way clutch in a first rotational direction to increase a force of engagement between the input and output members. The stator is operable to apply a second magnetic driving force to cause movement of the portion of the one-way clutch to disengage the input and output members from each other.

A pump device includes a casing, an impeller, a base, and a motor. The casing includes a pump chamber, and an inlet and an outlet. The impeller is accommodated in the pump chamber. The motor is connected to the casing for driving the impeller to rotate and includes a rotor chamber for receiving a rotor. The base is disposed between the impeller and the motor and includes an accommodating groove having an inlet port in communication with the rotor chamber to allow fluid in the pump chamber to enter into the rotor chamber. In the pump device, precipitation has been performed to fluid in the accommodating groove before the fluid enters into the rotor chamber, thus the impurity particles can be prevented from entering into the rotor chamber, thereby prolonging the service life of the pump device.

A water cooling head includes water cooling head includes a casing, a base and a pump. The casing includes an inlet and an outlet. An outer side of the base has a heat-absorbing surface. A thermal conduction structure is disposed on an inner side of the base. An active space is defined by the base and the casing collaboratively. The pump includes a first magnetic element, a second magnetic element, an impeller and a pivotal part. The first magnetic element is located outside the active space. The first magnetic element is arranged between the impeller and the base along a direction perpendicular to the base. The pivotal part, the second magnetic element and the impeller are disposed within the active space. The pivotal part is connected with the impeller and arranged between the impeller and the base. The second magnetic element is installed on the pivotal part.

A sensing device for a centrifugal slurry pump having an impeller which rotates about an axis, the centrifugal slurry pump including a side liner and a main liner housed within an outer casing of the pump, the sensing device comprising; a body portion arranged to pass through the outer casing, wherein the body portion includes a sensor biased towards contact with either the side liner or the main liner of the pump.

A centrifugal pump includes a motor with a shaft and an adapter mounted to the motor. A volute housing mounted to the adapter defines a volute chamber. The adapter and volute housing define a pumping chamber therebetween. The volute housing includes an impeller inlet wall having an orifice. An impeller is disposed within the pumping chamber and a hub of the impeller is mounted on the shaft while a shroud portion coincides with the impeller orifice. An inducer is coupled to the shaft and extends into the inlet dogleg. A first portion of the inducer resides within the shroud portion of the impeller and a second portion of the inducer resides within the inlet orifice. The inducer includes helical blades whereby, upon rotation of the shaft, a fluid within the inlet dogleg is acted upon by the helical blades of the inducer before the fluid enters the impeller shroud portion.

A pump for a fluid which can be blood has a stator housing and a rotor hub with leading and trailing portions and an intermediate portion disposed therebetween. At least one impeller blade at the leading portion drives circumferential and axial components of a flow into a pump annulus or intermediate pathway portion. At least one stator blade extends radially inward from the stator housing within the intermediate pathway portion and is configured to reduce a circumferential component of the flow.

A self-priming, centrifugal pump comprising a first housing part having a front wall with an inlet, a second housing part having an outlet, an impeller rotatably arranged in the second housing part and a pump screw rotatably arranged in the first housing part, connected to the impeller and comprising a center body around which a helical blade is arranged for feeding the impeller with any gas that is present in the liquid, wherein the center body is arranged at a distance from a side of the front wall that faces the center body, such that a channel with a width of at least 12 mm is formed between the center body and the side of the front wall that faces the center body.

A boost pump includes a boost cover and a main pump housing engaged opposite to the boost cover with an impeller rotatably engaged between the boost cover and main pump housing. The impeller includes an inducer section comprising a hub including a plurality of axial blades extended therefrom, each of the plurality of blades including a root, a tip, first and second surfaces, wherein the each of the first and second surfaces is defined in TABLE 1. The impeller includes an impeller section comprising a shroud extending from the hub including a plurality of radial blades extended therefrom. Each of the plurality of blades can include including a root, a tip, and opposed pressure and suction sides extending from the root to the tip, wherein the each of the pressure and suction sides is a surface defined in at least one of TABLES 2-4.

A pump for a fluid which can be blood has a stator housing and a rotor hub with leading and trailing portions and an intermediate portion disposed therebetween. At least one impeller blade at the leading portion drives circumferential and axial components of a flow into a pump annulus or intermediate pathway portion. At least one stator blade extends radially inward from the stator housing within the intermediate pathway portion and is configured to reduce a circumferential component of the flow.
