Abstract: A computer system uses a modular fan design. Multiple fan modules can be used, and identical fan modules can be used for directing air into and out of the computer system enclosure. Each fan module is hot swappable, and can be replaced quickly without the use of tools or fasteners. Optional mounting features on the fan and the computer enclosure prevent misassembly, and an optional color coding scheme aids in assembly. An optional splitting light pipe directs light from a single status-indicating source to both the front and back of the fan module.

Abstract: A mixer box for mixing two separate sources of air. Air from a first source is fed into a plurality of vented conduits. Each of the vented conduits has at least one vent opening, that allows the air from within the conduits to escape and enter a mixing chamber. Air from a second air source flows into the mixing chamber around the vented conduits. As the second air source flows around the vented conduits, turbulence is produced that mixes the second air source with the first air source escaping from the vented conduits. Flaps are used to control the flow of the first source of air out of the vented conduits and the flow of the second source of air around the vented conduits.

Abstract: A heating system is provided for heating fresh water on boats, marine vessels and the like. The boat's water supply is connected to a hot water tank, which in turn is in fluid communication with a heat exchanger. The coolant line for a boat engine passes through the heat exchanger, through the hot water tank and back to the engine. Heat from the engine is transferred from the coolant line to the water in the hot water tank at a rate that varies with engine operation. The heat exchanger allows additional heat transfer to the water as the coolant and water pass through the heat exchanger. A sensor regulates circulation of water through the heat exchanger. The heat exchanger may be retrofitted externally of an existing hot water tank by connecting the heat exchanger to existing water lines for the hot water tank and to an existing engine coolant line to effect heat transfer from the engine coolant line.

Abstract: A heating panel system comprises a cylindrical hot water pipe. The pipe is in a linear configuration. A plurality of rigid fins is provided. The fins have apertures. The apertures allow the fins to be positioned over the pipe. In this manner inlet openings are formed. The inlet openings are of an enlarged size beneath the pipe and outlet openings. The pipe and outlet openings are of a reduced size above the pipes. In this manner the flow of heated air between the fins and across the pipe is increased due to venturi configuration of the design.

Abstract: This invention relates to a hybrid electric vehicle component coolant control system and method. The coolant system has an electric pump to move coolant through a closed system including engine and motor components. Such components to be cooled can include any electric motors, power electronics, engine, and transmission. The preferred embodiment controls coolant flow to the vehicle engine and motor in a single closed loop. Vehicle components have temperature sensors that send temperature signals to an electric coolant pump duty cycle control strategy. The control strategy makes a determination of a duty cycle of the electric coolant pump as a function of the temperatures of vehicle components and orders the duty cycle of the electric pump. In the preferred configuration, engine temperature sensors can acquire either engine coolant temperature or engine cylinder head temperature.

The basic air partition member can be shaped and contoured to form inside or outside corners of the air passageway and to include appropriate openings, as required, to vent the conditioned air to the work site and to allow for the passage of electrical wires or the like through and across the air passageway.

Abstract: A vent assembly for mounting in a passageway extending through an exterior wall to provide ventilation to the space bounded by the exterior wall includes an apertured panel exteriorly juxtaposed with a security grate to prevent unauthorized intrusion through the exterior wall. Carriage bolts extend through the apertured panel and security grate into engagement with an anchoring element, such as a pair of L-shaped brackets disposed on opposed sides in the passageway. The smooth surfaced head of the carriage bolts, coupled with the square cross-section of the shank adjacent the head mating with square apertures in the apertured panel and in the security grate prevent turning of the carriage bolts from a location external to the exterior wall. Air through the passageway may be filtered with an air filter supported by bolts extending from the security grate.

Abstract: In an apparatus for distributing air flowing along a first path, the first path splits into second and third paths, so that both the second and third paths diverge from the first path. The second and third paths are at an angle of less than 180° to one another. A first door, is across the second path; and a second door, is across the third path. A common operating device rotates both doors, such that air is able to flow from the first path into the second and third paths, the flow being dependent on the position of rotation of the doors.
