a water pump cooler for CPU wherein coolant may efficiently perform heat exchange, comprising at least: at least a heat absorbing component, at least a heat-transfer water pump, at least a heat exchange component and connecting water pipes, wherein a closed loop is formed by the heat-transfer water pump, connecting water pipes and heat exchange component. The heat-transfer water pump is disposed above the heat absorbing component to serve as a cycle power source for the coolant. The heat-transfer water pump includes at least a water pump component, which includes at least a base plate and a plurality of rotor axial impeller sections and rotor centrifugal impeller sections. The coolant is driven by the rotor axial impeller sections to flow into the rotor centrifugal impeller sections, and is then thrown at a high speed by the rotor centrifugal impeller sections to the heat exchange component for efficient heat dissipation. In this way, the coolant may perform heat exchange at a high speed within the closed loop.

A laundry treating apparatus includes a duct system including an air discharge duct for discharging air inside the drum to an outside of the drum, an air supply duct for supplying air to the drum, and a connection duct for connecting the air discharge duct and the air supply duct to each other. The apparatus also includes a heat-absorber disposed inside the connection duct to remove moisture from air, and a heat-emitter disposed inside the connection duct to heat air passing through the heat-absorber. The apparatus further includes a water ejector disposed in the duct system and defining a water flow path for supplying water to the heat-absorber to remove foreign substances remaining on the heat-absorber.

A plug-in electronic expansion module for pump electronics of a centrifugal pump for expanding the pump electronics with at least one additional function has a housing having a lower face and connecting formations thereon for attachment to a pump housing of the pump electronics. Electronics in the module housing provide the additional function. A base is provided on the lower face, and an electrical interface connected to the pump electronics includes a flat support projecting tongue-like from the base on the lower face of the module housing through an opening in the pump housing and carrying contact-forming electrical traces.

A submersible, water circulation system for enclosed tanks such as used by municipalities, fire districts, and industries. The system includes a driving unit having a shell extending along an axis with a pump supported within the shell. The shell has at least one inlet and at least one outlet and is positionable on the floor of the tank with the outlet facing upwardly. The upwardly facing outlet is preferably a thin, upwardly facing, elongated slot and creates a thin, substantially planar discharge of water therethrough that is directed upwardly toward the surface of the body of water. The substantially planar discharge presents a very large surface area for its volume and induces water adjacent the outside of the shell of the driving unit to move upwardly with it toward the surface of the body of water.

A pump includes a housing, a drive shaft, a centrifugal pump portion having an impeller, and a gear pump portion having first and second gears. The impeller and one of the first and second gears are mounted to the drive shaft to drive the centrifugal pump portion and the gear pump portion at the same rotational speed. The gear pump can be a crescent internal gear (CIG) pump. The drive shaft can be rotated by a magnetic drive. The drive shaft can include a longitudinal bore in fluid communication with a cavity in the magnetic drive and with a discharge of the centrifugal pump portion to circulate working fluid through the magnetic drive to cool the drive. An impeller can be coupled to an inlet of the centrifugal pump portion.

An example water well submersible pump filter may comprise: (1) a perforated cap; (2) a hollow cylindrical middle member joined to the perforated cap at a first end of the hollow cylindrical middle member, wherein the hollow cylindrical middle member comprises a perforated hollow cylindrical segment proximate to the first end of the hollow cylindrical middle member; and (3) a filter crown joined to a second end of the hollow cylindrical middle member, wherein the filter crown comprises a ring of fins extending approximately parallel to an axis of the hollow cylindrical middle member.

A mobile emergency water supply and drainage device is provided, which relates to the technical field of emergency rescue and disaster relief equipment. The device includes a submersible pump, relay pumps, and an electric power supply device for providing electric power for the submersible pump and the relay pumps. Frequency conversion control cabinets are arranged between the submersible pump as well as the relay pumps and the electric power supply device, and the submersible pump and the relay pumps are connected in series by pipelines for remote water supply and drainage. The device further includes a floating body for suspending the submersible pump in water, and the floating body floats on a surface of the water and is connected with the submersible pump through a lifting chain.
