Abstract
Housing with directed-flow cooling (10) for computer (110) provides auxiliary airflow for cooling a heat-sensitive component, such as CPU (120). Housing (10) includes partition (60) that separates housing (10) into a lower compartment (40) for enclosing computer (110) and an upper compartment (20) for receiving ambient air through slots (24). Partition (60) includes vent opening (61) above CPU (120) that allows air to flow from upper compartment onto CPU (120), directed by impingement fan (50).
Claims12
A housing for an electronic device that includes a plurality of components, at least one being a heat-generating component and at least one being a heat-sensitive component;
- said housing including:
- a partition separating said housing into two compartments;
- said compartments comprising:
- a lower compartment for enclosing the heat-generating and heat-sensitive components;
- including:
- an air intake grille for receiving ambient air into said lower compartment;
- a floor for supporting components of the electronic device;
- and
- side walls connected to the edges of said floor and extending upward;
- including:
- an exhaust outlet for allowing hot air to flow out of said lower compartment;
- including an exhaust fan for directing warm air out of said exhaust outlet;
- wherein said plurality of heat-generating components are between said air intake grille and said exhaust outlet and
- an upper compartment for receiving ambient air;
- including
- a cover;
- side walls connected to the edges of said cover and extending downward;
- including:
- an air inlet for admitting ambient air into said upper compartment;
- and
- an impingement fan;
- and wherein said partition includes a vent opening located near the heat-sensitive component for allowing cool air to flow from said upper compartment onto the heat-sensitive component;
- and said impingement fan impels cool air to move through said vent opening toward said heat-sensitive component.
