HVAC devices with improved uniax design and functionality

An aero-acoustical fan intake device, comprising:

• an inlet face comprising an inlet opening configured to receive a flow of a fluid, wherein the inlet face has a hemisphere or bulb shape that is surrounded by the inlet opening;
• a discharge face comprising a discharge opening configured to discharge the flow of the fluid;
• and
• a housing that encompasses a flow channel that extends from the inlet opening to the discharge opening according to a conical shape, wherein a cross-sectional area of the flow channel varies between the inlet opening and the discharge opening in a manner that is determined to cause the flow of the fluid through the flow channel to continuously accelerate from a first location of the channel to the discharge opening;
• wherein an inner wall of the flow channel and an outer wall of the flow channel extend in straight lines angling towards a central axis of the flow channel from the inlet opening to the discharge opening.

A method of fabricating a fan intake device, comprising:

• forming, by a device comprising a processor, an inlet face surrounded by an inlet opening configured to receive a flow of a fluid;
• forming, by the device, a discharge face surrounded by a discharge opening configured to discharge the flow of the fluid;
• and
• forming, by the device, a housing that encompasses a channel that extends from the inlet opening to the discharge opening, wherein a cross-sectional area of the channel continuously decreases from a first location of the flow channel until the discharge opening to cause the flow of the fluid through the channel to continuously accelerate from the first location of the channel to the discharge opening;
• wherein an inner wall of the flow channel and an outer wall of the flow channel extend in straight lines angling towards a central axis of the flow channel from the inlet opening to the discharge opening.
