Abstract
Examples herein relate to fan bodies with pressure regulating chambers. For instance, in some examples a fan body can define an outlet, an inlet, a fan chamber that is in fluidic communication with the inlet and the outlet, and a hollow pressure regulating chamber having an opening that is in fluidic communication with the fan chamber.
Claims18
A fan body, comprising:
- a surface defining a fan chamber having volume that extends from an inlet of the fan chamber to an outlet of the fan chamber;
- and
- a hollow pressure regulating chamber extending into the surface defining the fan chamber to provide an additional volume and having an opening to the additional volume of the hollow pressure regulating chamber that is in fluidic communication with the volume of the fan chamber to permit fluid flow between the volume of the fan chamber and the additional volume to regulate a pressure of fluid in the volume of the fan chamber.
A fan comprising:
- a fan body including a surface defining a fan chamber having volume that extends from an inlet of the fan chamber to an outlet of the fan chamber:
- and
- a hollow pressure regulating chamber extending into the surface defining the fan chamber to provide an additional volume in addition to the volume of the fan chamber, and having an opening that is positioned adjacent to a fluid flow path extending from the inlet of the fan chamber to the outlet of the fan chamber and is in fluidic communication with the volume of the fan chamber to permit fluid to flow between the volume of the fan chamber and the additional volume to regulate a pressure of fluid in the volume of the fan chamber;
- and
- a rotational element disposed in the fan chamber.

An electronic device comprising:
- a heat-generating component;
- and
- a fan including:
- a fan body having a surface defining a volume of a fan chamber extending from an inlet of the fan chamber to an outlet of the fan chamber;
- a curved hollow pressure regulating chamber extending into the surface defining the fan chamber to provide an additional volume in addition to the volume of the fan chamber, and having an opening that is positioned along a fluid flow path extending from the inlet of the fan chamber to the outlet of the fan chamber that is in fluidic communication with the volume of the fan chamber and the additional volume to permit fluid flow between the volume of the fan chamber and the additional volume to regulate a pressure of fluid in the volume of the fan chamber, wherein the curved hollow pressure regulating chamber extends into the surface of the fan chamber in a direction that is substantially opposite of a direction of the fluid flow path;
- and
- a rotational element disposed in the fan chamber to receive a fluid via the inlet of the fan chamber and cause the fluid to flow along the fluid flow path to the outlet of the fan chamber.
