摘要： A rotor for a supercharging device may include a compressor wheel and a turbine wheel. A sealing disc may be arranged between the compressor wheel and the turbine wheel. The sealing disc may include a first side interfacing with the compressor wheel and a second side interfacing with the turbine wheel. The compressor wheel and the turbine wheel may each define one of a holding contour and a counter-holding contour, which respectively interact with a corresponding one of a holding contour and a counter-holding contour defined on each of the first side and the second side of the sealing disc. The respective holding contour may correspond to the respective counter-holding contour, which may engage in one another and secure the compressor wheel, the sealing disc and the turbine wheel to one another.

摘要： A cooling system that includes two or more fans that each have a chassis. The chassis includes a first face, a second face, and a sidewall. The fans then can be attached to each other by attaching a sidewall of a first fan chassis to a sidewall of a second fan chassis. An adjustable vane is attached perpendicularly and approximately equidistant between the fans, with an angular control element that is attached to the first fan chassis. The vane can be oriented such that the vane divides the airflow distributed to the fans. The vane then can be adjusted radially by the angular control element, which is attached to the fan chassis. If an impeller of a fan chassis fails the vane can be adjusted radially using an angular control element to distribute more airflow to the failed fan superimposing the non-failed fan chassis.

摘要： A counter-rotating wet gas compressor for deployment and operation on the sea floor is described. The compressor has alternating rows of impellers, with each successive row of impellers being mounted a central hub or to an outer sleeve. According to some embodiments, no static diffusers are positioned between the alternating counter-rotating rows of impellers such that the design is structurally robust, compact and capable of compressing fluids that contain significant portions of liquid phase.

摘要： A counter-rotating axial flow fan with reduced noise at the target operating point achieved without modifying a front impeller, a rear impeller, or a middle stationary portion is provided. An annular rib including a projecting surface for generating turbulent flow is formed on an inner wall portion of a casing at a position off from the middle stationary portion to a side of the rear impeller, the projecting surface extending radially inwardly of the inner wall portion and extending continuously in the circumferential direction of the inner wall portion. A fluid striking the projecting surface for generating turbulent flow is partially disturbed to form a turbulent flow before entering an area in which the rear impeller is provided. The turbulent flow suppresses flow separation of a fluid flowing along the surfaces of rear blades of the rear impeller from the surfaces of the rear blades.

摘要： A cooling fan assembly for an electronic apparatus includes a casing and first and second centrifugal fans for creating airflow through the casing to dissipate heat associated generated by the electronic apparatus. The casing has at least first and second air inlets and an air outlet. The first centrifugal fan is received in the casing and positioned proximate the air outlet, and the second centrifugal fan juxtaposed with the first centrifugal fan is also received in the casing and positioned proximate the air outlet and indirect fluid communication therewith. The first and second centrifugal fans and the casing further are configured such that the airflow is effectively induced to form a high-pressure volute tongue in a region bounded by the first and second centrifugal fans and the air outlet.
