Abstract: The disclosure provides a fluid-cooled heat sink having a heat transfer base and a plurality of heat transfer fins in thermal communication with the heat transfer base, where the heat transfer base and the heat transfer fins form a central fluid channel through which a forced or free cooling fluid may flow. The heat transfer pins are arranged around the central fluid channel with a flow space provided between adjacent pins, allowing for some portion of the central fluid channel flow to divert through the flow space. The arrangement reduces the pressure drop of the flow through the fins, optimizes average heat transfer coefficients, reduces contact and fin-pin resistances, and reduces the physical footprint of the heat sink in an operating environment.

Abstract: The present invention provides systems and methods of controlling local environment. In one embodiment, incoming air enters a contactor such the Direct Contact Cooler-Condenser (DCCC) where the air contacts water distributed on the contact media. After passing through the DCCC, the air is saturated at a temperature equal or close to that of the water. Depending on the state of the incoming air, in the DCCC will be humidified or dehumidified to yield saturated air at the desired humidity ratio. In one embodiment, a blower draws air through the DCCC and blows into the heater. The heater heats the air to the desired dry-bulb temperature. Before exiting, the air may pass through a filter.

Abstract: The present invention provides a system for controlling the climate of a hybrid vehicle. The system includes a thermoelectric module, a heat exchanger, a pump, and a valve. The thermoelectric module includes thermoelectric elements powered by electric energy. The thermoelectric elements emit or absorb heat energy based on the polarity of the electrical energy provided. A tube containing coolant runs proximate the thermoelectric elements. To aid in the transfer of heat energy, a blower is provided to generate an air flow across the thermoelectric elements and the tube. The coolant is provided from the thermoelectric module to a heat exchanger that heats or cools the air flow provided to the cabin of the vehicle. The pump and valve are in fluid communication with the heat exchanger and thermoelectric module. The pump pressurizes the coolant flow through the tube and coolant lines. In a cooling mode, the valve is configured to selectively bypass the engine coolant system of the vehicle.

Abstract: The invention relates to a heat exchanger of a plate-type construction having first flow channels for a first medium, each formed by a pair of plates, and having corrugated ribs, around which a second medium flows, arranged between neighboring plate pairs. In order to provide an improved heat exchanger which allows a more compact construction of the plant when used in a heating or air conditioning unit of a motor vehicle, it is proposed that the corrugated ribs and at least one of the neighboring plate pairs form second flow channels for the second medium and the second flow channels have a curved course, so that the second medium undergoes a change of flow direction on flowing through the heat exchanger.

Abstract: A cold plate for a beverage chilling apparatus comprising a plurality of beverage conducting tubes sinuously arranged within a cast aluminum jacket. Interleaved between the beer conducting tubes are coolant conducting lines arranged in heat exchanging relation. The coolant lines are derived from a main coolant line pumping coolant to the cold plate, where a coolant inlet is divided into two separate smaller intermediate coolant segments at a first stage. Each intermediate glycol segment is then subdivided at a second stage into four heat exchanging coolant lines. At each subdivision of the coolant fluid conducting system, a pair of smaller lines equal distance from a feed line and having a smaller diameter than the feed line are incorporated using a two-for-one splitter so that each stage doubles the number of lines from the previous stage.

The plate includes holes to accommodate the leads of the component and mounting flanges that partially surround the component and are used to mount the heat sink. In the mounted position, the heat sink is held in thermal communication with the component directly or through a thermally conductive material.

Abstract: A coolant sensor doubles as a bleed valve for purging trapped air from a cooling system. The sensor slides into a port placing a sensor element in contact with the coolant. The sensor includes a pair of encircling o-rings for sealing the system from atmosphere in one position and permitting bleeding in a second position. The bleed channel is in the sensor port between the o-rings. The sensor is moved so the innermost o-ring clears the narrow opening into the cooling system. The outermost o-ring maintains a seal to keep the coolant from leaking out of the sensor port. The sensor is held in either position by a horseshoe clip or by a bayonet arrangement, the horseshoe clip arrangement including multiple apertures for each position, the bayonet having a position to provide for safe bleeding of air from the cooling system without completely removing the sensor from its retention port.

The power source is used to drive the electrodes to produce turbulence to fluids passing through the fluid channels according to measured mass flow rates from the sensor units, so as to facilitate uniform fluid flows in the plurality of fluid channels and reduce effect of thermal boundary layer in the fluid channels to thereby enhance heat transfer performance for the heat exchanger.

Abstract: The ventilating system includes evaporative cooling of the exhaust air before it enters a heat exchanger to cool incoming fresh outside air. A suction fan pulls exhaust air through the heat exchanger and, in combination with a flow restrictor, reduces the pressure on the exhaust air and augments the evaporative cooling. The use of a pusher fan to force outside air through the heat exchanger ensures that any leakage in the heat-exchanger results in outside air entering exhaust air and minimizing the chances of contamination by leaking exhaust air into the incoming fresh air. The heat exchanger is made economically by heat-forming cavities in relatively thick thermo-plastic sheets, interleaving them with other thermo-plastic sheets having separate gas flow conduit structures, and securing the sheets together. Preferably, the heat-exchanger is an opposed-flow heat-exchanger giving improved heat-transfer efficiency.

There is also disclosed a multiple systems combined heat exchanger having an opposing headers with beveled end walls, wherein at least two heat exchangers independent of each other share the respective headers which are divided from each other by separator walls.
