Appl. No.:

09/882655

Inventors:

Michael R. Cosley - Crystal Lake IL
Don C. Mueller - Aurora IL
Ramon E. Rodriguez - Chicago IL

Assignee:

Marconi Communications, Inc. - Cleveland OH

International Classification:

F25D 2312

US Classification:

622592, 62263, 165 804

Abstract:

A simple, reliable, compact, low cost and low power cooling system is disclosed. The cooling system is especially suited for an electronic equipment enclosure which is located out-of-doors. The cooling system runs on community AC power which is converted to DC. If community power is disrupted, the cooling system takes power from back-up batteries. If a compressor of the cooling system drops to a temperature of 0Â C. , a heating subsystem including a conduit loop that runs around the compressor and into the equipment chamber of the enclosure for transporting a heat transferring fluid, is activated for transferring heat from the equipment chamber to the compressor. A closed conduit loop is used to pump a mixture of ethylene glycol between the vicinity of the compressor and the interior of the equipment chamber. In this way, heat generated by the equipment to be cooled is transferred to the compressor to heat the enclosed refrigerant and the equipment is simultaneously cooled. The power required by the system is very low, because the system is compactly constructed and the arranged for maximum efficiency.

International Classification:

F25B 902

US Classification:

62 5, 622382

Abstract:

A cooling and heating system using a vortex tube is disclosed. The system is attached to an equipment enclosure used for telecommunications, cable television and the like where a cold airstream from the vortex tube is directed to the sealed upper chamber of the enclosure, the upper chamber typically containing heat generating electronic components. The hot airstream generated by the vortex tube can be used to maintain an elevated temperature which prolongs the life of certain batteries and enhances their efficiency. Cold plates, heat exchangers, air jets and the like may be used in conjunction with the vortex tube to increase the cooling or heating of preselected components or items.

International Classification:

F25B 2900

US Classification:

165263, 165264, 165 481, 165 59, 62 36, 622592

Abstract:

A method which extends the useful life of a lead-acid type battery by applying conductive cooling or heating directly to the bottom surface of the battery to maintain the battery at a constant temperature of about 25Â C. regardless of the ambient temperature surrounding the battery. The method for thermally managing the battery comprises the steps of providing an equipment cabinet having an equipment chamber, providing the cabinet with a battery compartment exposed to ambient temperature changes, providing the battery, placing the battery in the battery compartment, providing a cold plate having a surface substantially coextensive with the surface of the battery, placing the surface of the cold plate in direct contact with the surface of the battery, providing a heating pad, placing the heating pad in direct contact with the cold plate, providing an insulation pad, and placing the insulation pad between the heating pad and a mounting for the cabinet.

Abstract:

A top cover for an electronic equipment cabinets where the top cover is made of upper and lower synthetic resin panels which are welded at their edges to form an air chamber therebetween. The upper panel is domed while the lower panel has a corrugated like structure. Access ports are provided which may be sealed shut. Rain directing berms are also provided to direct rain to the corners of the cover and away from access doors to a sealed electronic equipment chamber in the cabinet. A lateral air and water exhaust duct extending the width of the cover is provided as a path for exhaust air from a heat exchanger which normally moves in one direction but under high wind conditions may move in the opposite direction and for allowing the passage of rain water from one side of the cabinet to the opposite side.

Abstract:

A microscale chip cooling system for a heat dissipating item, such as Intels Pentium brand microprocessor. The system includes a 40 millimeter by 40 millimeter thermally insulated housing including a base and a cover. The system also includes a thermally conductive evaporator. The evaporator is adapted to be attached to a heat source such as the microprocessor. The cover includes inlet and outlet ports and the base includes a capillary passage. A refrigerant or heat transferring fluid is pumped or past through the passage before making a sudden expansion in an expansion zone just before passing to an evaporator chamber. Pool and flow boiling and forced convection may occur in the evaporator chamber as heat is transferred from the microprocessor through the thermally conductive evaporator to the refrigerant. The refrigerant then returns to a compressor to repeat the cycle. The system is extremely small and very efficient.

International Classification:

F25B 2900

US Classification:

165263, 165 47, 622592

Abstract:

An equipment cabinet mounted on a concrete pad. The cabinet includes an upper equipment chamber, a lower back-up battery chamber and a heat exchanger. Ambient air is drawn across batteries in the lower chamber before being drawn into the heat exchanger to help cool electronic components in the upper chamber. Air in the upper chamber is separate circulated through the heat exchanger. A cold plate is placed beneath the batteries and is connected to a refrigeration system. A heating pad is located below the cold plate and is separated from the concrete pad by insulation. The cold plate and the heating pad are used to maintain the batteries at about 25Â C. regardless of ambient temperatures so as to extend the useful lives of the batteries.

US Classification:

16510433, 165 804

Abstract:

A more efficient cooling system for densely packed electronic components for use in an out-of-doors equipment enclosure. An array of cooling assemblies are placed on heat generating components mounted to printed circuit boards mounted in enclosure racks. Each board has a manifold for intake and exhaust of refrigerant, and larger rack manifolds are substituted for rails and are attached to a backplane. A hybrid package including a ceramic hybrid power module and an attached array of cooling assemblies provide even more density of components and improved cooling.
