摘要： A centrifugal air-sending device has blades that each have a vane length in a first region that is greater than a vane length in a second region, and are each formed such that a proportion for which a turbo vane portion accounts is higher in a radial direction than a proportion for which a sirocco vane portion accounts in the first region and the second region. The blades that are located closer to an outer circumference than is a blade inner diameter of inner circumferential ends of the blades at end portions of the blades that are close to a side plate in an axial direction are defined as a blade outer circumferential portion that is formed such that a vane thickness of each of the blades in decreased in the radial direction from an inner circumference toward the outer circumference.

摘要： A fan includes an inlet part disposed to form a fan inlet, a base disposed to form, together with the inlet part, a fan outlet, and a blade. The blade extends from the base to the inlet part, and includes a first guide surface having an inclination toward an outside of the fan in a radial direction of the fan which changes in a direction from the inlet part toward the base, and a second guide surface having an inclination toward the outside of the fan in the radial direction which changes in a direction from the base toward the inlet part.

摘要： Disclosed herein are devices, methods, and systems for heat exchange, comprising one or more multi-disk rotors, one or more finned thermal elements, and a cover, which, even without an external fan, are combined in one apparatus to form a directed movement of fluid and heat exchange. Additional embodiments comprise an additional circulation chamber, integrated with/within said apparatus and/or external fans and/or at least one baffle in a circulation chamber for further directing and intensifying a changing of temperature of fluid passing through the apparatus. A highly efficient heat exchange is achieved by a high temperature gradient near the heat transferring surface and by a high-volume pumping capability of the multi-disk fan. The devices, methods, and systems are particularly applicable in fields that require compactness and low noise levels during operation, such as air conditioning and CPU cooling.

摘要： A fin array is disclosed for use in a centrifugal fan having a housing and a fan wheel, the fin array having: a first tube in a first plane perpendicular to an axis of the fan wheel; a second tube in a second plane parallel to the first plane; and a fin in a third plane parallel to the first place. The fin is sandwiched between the first tube and the second tube, all of which partially surround the axis of the fan wheel. The fin comprises a slotted fin apparatus for permitting condensate to move from a region between the fan wheel and the first tube to a region between the first tube and the housing. The slotted fin apparatus has a first cutout disposed between a first extension and a second extension along at least a port of the length of the fin.
