Abstract
Manufacturing techniques and architectures directed to an improved fan device that can be integrated into an evase. Manufacturing techniques of an improved evase device can be designed with rounded corners that can facilitate, e.g., mitigation of reverse flow that traditionally grows back from corners of a transition from an axial fan to a rectangular duct.
Claims20
A method of fabricating an evase device, comprising:
- forming, by a device comprising a processor, a housing that encompasses a channel that extends in a longitudinal direction from a first side of the housing to a second side of the housing;
- forming, by the device, a first opening in the housing that is situated at the first side of the housing, wherein the first opening is configured to receive a flow of a fluid discharged by a fan;
- forming, by the device, a second opening in the housing that is situated at the second side of the housing, wherein the second opening is configured to discharge the flow of the fluid into a duct;
- forming, by the device, rounded corners at the second side of the housing, wherein the rounded corners are determined to mitigate a reverse flow of the fluid at corners of the duct;
- and
- forming, by the device, a central pod having a shape that is cylindrical over an entire length from the first opening to the second opening and is determined to reduce impact loss at the second opening.
