摘要:
A coupling is configured to hold detachably a speaker on a computer component by a gravitational force acting on the speaker. The coupling may be a pocket on the component and a flange on the speaker. The coupling may include vertically aligned projecting elements on the component and corresponding receptacles on the speaker. The coupling may be hidden after the speaker has been mounted. To attach the speaker it is held near the component and then lowered with respect to the coupling mechanism to reach a position where the speaker is fixed relative to the component by a gravitational force.

A computer housing is provided with enhanced interior cooling, to dissipate operating heat from its heat generating internal electronic components, using a single cooling fan disposed inside the housing. During operation thereof the fan draws ambient cooling air into the housing through a hollow support foot attached to the underside of the housing, and the bottom end opening of a hollow front bezel structure, flows the cooling air through the housing and then discharges it therefrom. A pull-out option card carrier defines an interior housing baffle that routes a large portion of the interior housing air flow across the processor portion of the computer motherboard. Additionally, a smaller quantity of ambient cooling air is drawn through side wall openings in the housing into an interior plenum upon the inner side wall of which the motherboard is mounted. The plenum air is passed into the main housing interior through a transfer opening in the inner side wall and then drawn along the balance of the motherboard through a gap between the motherboard and the installed option card carrier.
摘要:
A natural convection cooled electronic device utilizing a box-like plastic enclosure surrounding the circuitry of the electronic device. The apparatus further includes aluminum heat sinks fastened in good thermal contact with heat dissipating components of the electronic device, wherein the heat sinks include heat fin members which run parallel to the inner walls of the enclosure and are separated from the walls by an air gap. The inner walls of the enclosure are lined with a layer of thermally conductive material, such as copper foil, which spreads the internal heat flux across the total surface area of the enclosure. The exposed surface of the heat flux spreader layer and the facing surface of the heat fin members are further made semi-rough and stained black to eliminate potential hot spots and to increase radiant heat transfer between the heat sinks and the enclosure.

The insulation layer may include openings to allow contact of the heat flux spreader layer to the electronic circuitry at grounded locations.

A computer system has control circuitry for detecting directly and independently of temperature the malfunctioning of a fan used for cooling the housing of the computer and for controlling the power supply voltage when malfunctions are detected so as to reduce the temperature within the housing of the computer system.
摘要:
A personal computer has at least one heat producing element within its housing with a fan for cooling the inside of the housing. The fan is controlled by a temperature dependent fan control circuit. A heat sensing device within the fan control circuit adjusts the voltage applied to the fan in a substantially continuous relationship to the temperature inside the housing.
