ActiveCN119628323Aachieve separationno distractionMagnetic circuit rotating partsCooling/ventillation arrangementThermodynamicsCooling coil
The invention discloses a method for improving the cooling effect of a pole winding based on a mixed-flow fan, and belongs to the technical field of cooling of high-rotating-speed and high-capacity hydraulic generators and pumped storage generator motors. Mixed-flow fans are arranged at the two ends of a magnetic yoke, and cooling air is divided into radial cooling air for cooling coils at the ends of the magnetic poles and axial cooling air entering the outer surfaces between the magnetic poles. An interelectrode outer surface ventilation cooling space is formed between every two adjacent pole windings, interelectrode ventilation partition plates which are axially arranged are arranged in the interelectrode outer surface ventilation cooling spaces, and separated axial ventilation air channels are formed by the interelectrode ventilation partition plates and the outer surfaces of the pole windings; therefore, rotor pole winding cooling of a high-rotating-speed and high-capacity hydro-generator and a pumped storage generator motor in which radial ventilation cooling cannot be adopted in a pole winding interelectrode area is ensured, and the problem that the difference between the cooling effects of the windward side and the leeward side of a traditional structure is large is solved.

A wind deflector and a server
This application discloses an air guide shroud and a server, relating to the field of server air guide structure technology. It includes an air guide plate, which is positioned on the side of the server's memory module away from the memory slot. The air guide plate has at least one movable first deflector at its air inlet end and at least one movable second deflector at its air outlet end. The first and second deflectors are positioned opposite each other to correspond to the two ends of a memory slot. Both the first and second deflectors can switch between two positions to block or avoid the corresponding memory slot. By switching the positions of the first and second deflectors, airflow to areas without installed memory is prevented from being lost or consumed, thus preventing hot air recirculation. This allows for precise airflow guidance for different memory configurations, solving the technical problem of partial loss of cool airflow when the memory slot is empty. This achieves the technical effect of improving the air guide shroud's airflow capacity and heat dissipation.
