An air-cooled self-contained evaporator and condenser apparatus with no external power source, the apparatus including a cold plate having a first surface with recesses formed therein in a matrix or array corresponding to the matrix or array of chips on a multi-chip module or unit. The opposite surface of the cold plate includes a finned arrangement which, in conjunction with the cold plate, forms part of an isolated evaporation chamber of the cooling unit, with the chamber housing a boilable fluid which changes phase from liquid to vapor. Positioned above and contiguous with the isolated chamber is a condensing chamber, including a plurality of tubular passageways, the external portions of which are finned for ready removal of heat. For attachment of the cold plate portion of the unit to the chips, suitable heat transfer slugs, such as aluminum nitride slugs, are affixed in the recesses, with opposites surfaces thereof bonded to the exposed faces of the chips. Heat is transferred from the chips through the slugs, through the cold plate to cause boiling of the fluid within the chamber, the vapors of which are condensed in the upper part of the cooling unit to thus return as fluid to the chamber.

A system having: a midplane having air flow channels therein; a disk drive mounted to a first side of the midplane; and a temperature sensors mounted to the midplane. The system includes a pair of electrical chassis connected to a second side of the midplane. A first one of the chassis has therein: a fan; and a fan controller for controlling speed of the fan in response to a temperature control signal. A second one of the chassis has therein: a microprocessor for: detecting temperature signals produced by the temperature sensors; comparing differences between the detected temperature signals; and selecting one of the detected temperature control signal from the compared differences as the temperature control signal. A faulty one of the temperature sensors is detected by: selecting one of the detected temperature control signal as the faulty one of the plurality of temperature sensors from the compared differences.

A back flow preventing device is disclosed which prevents the reverse flow of water from a point of use into a water supply system. The device has a casing with coaxially aligned inlet and outlet openings, and containing coaxially aligned inlet and outlet check valves. The coaxial alignment of the inlet and outlet openings, and of the inlet and outlet check valves serves to minimize the pressure drop through the device. Between the inlet and outlet check valves is a diaphragm actuated relief valve which opens to drain the passage between the check valves if they should malfunction or if there is a drop in the supply line pressure sufficient to cause actual or potential reverse flow back toward the supply line. The internally-located inlet and outlet check valves are each removably secured in place by internally-located retaining rings.

A method and computer program product for determining an internal temperature of a computing device, a power consumption factor for the computing device, and an airflow factor for the computing device. An approximated ambient air temperature is generated based upon the internal temperature, power consumption factor, and the airflow factor.
