Abstract
A new type of device, useful as a fan among other applications, in which fluid flow is induced by providing within the device a chamber of constantly increasing volume and a chamber of constantly decreasing volume. Fluid moves through these chambers impelled by the rotation of a pair of members linked together for rotation about skewed axes. The members move within a chamber having a spherical surface, into which open ports for inward and outward fluid flow. The device may be used to assist in cooling components of an electronic system such as a computer system.
Claims17
An apparatus, comprising:
- a housing defining a chamber with a spherical surface, an inlet port opening through said housing into a hemisphere of said chamber, and an outlet port opening through said housing from the same hemisphere of said chamber;
- a planar, disk-like first rotatable member mounted within said housing for rotation relative thereto and positioned to bound the hemisphere within said chamber, the hemisphere communicating with said inlet port and said outlet port;
- a shaft extending through the chamber skewed relative to a plane of said first rotatable member;
- and
- a planar, disk-like second rotatable member mounted within said housing for movement relative to said housing and to said first rotatable member, said second rotatable member, including:
- a first half disk portion extending from a first side of said first rotatable member along said shaft, wherein the first half disk portion includes a first planar side;
- and
- a second half disk portion extending from a second opposing side of said first rotatable member along said shaft, wherein the second half disk portion includes a second planar side, and wherein the first and second planar sides face a same direction;
- said second rotatable member mounted in said housing for rotation about the shaft and coupled to said first rotatable member for oscillation about an axis lying in the plane of said first rotatable member;
- said rotatable members cooperating one with another and with said ports to define an expanding volume opening from said inlet port and a contracting volume opening to said outlet port;
- rotation of said first and second rotatable members inducing a flow of fluid through said ports and said chamber.

An apparatus comprising:
- a first housing enclosing a heat producing electronic system;
- and
- a fluid flow inducing device coupled to said heat producing electronic system for impelling a cooling flow of fluid across said heat producing electronic system, said device comprising:
- a second housing defining a chamber with a spherical surface, an inlet port opening through said second housing into a hemisphere of said chamber, and an outlet port opening through said second housing from the same hemisphere of said chamber;
- a planar, disk-like first rotatable member mounted within said second housing for rotation relative thereto and positioned to bound the hemisphere within said chamber, the hemisphere communicating with said inlet port and said outlet port;
- and
- a circular planar second rotatable member mounted within said second housing for movement relative to said second housing and to said first rotatable member, said second rotatable member mounted in said second housing for rotation about an axis skewed relative to the plane of said first rotatable member and coupled to said first rotatable member for oscillation about an axis lying in the plane of said first rotatable member;
- said rotatable members cooperating one with another and with said ports to define an expanding volume opening from said inlet port and a contracting volume opening to said outlet port;
- rotation of said first and second rotatable members inducing a flow of fluid through said ports and said spherical chamber.
