Abstract: A high voltage alternator feeding power electronics and then one or more magnetic components to create a high current low voltage power system includes a substrate/buss plate performs heat extraction and electrical termination. The system includes a substrate (102) having a fluid passage member (106) disposed at least partially between the substrate. Power electronic and magnetic circuits (104) are operable to convert a high voltage, low current signal to a plurality of lower voltage signals having distinct voltage and/or current characteristics from the high voltage, low current signal.

Abstract: An electronics cooling system utilizing a refrigerant fluid that evaporates to remove heat from electronics and is condensed back to liquid through heat exchange with a cold medium (air or water). The refrigerant fluid is circulated via a liquid pump between the condenser and heated evaporators. A bypass circuit is provided to divert flow around the condenser during conditions of cold ambient temperatures, which is controlled by a feedback loop using a mechanical or electronic control valve. This prevents the refrigerant fluid temperature from becoming very low and potentially inducing condensation on the outside of the refrigerant tubing from the warm and moist indoor air.

Abstract: A cooling system having a pumped loop cooling system and an embedded vapor compression loop system for cooling air inside an enclosed space such as a container both when the required air temperature inside container is warmer or cooler than the outside ambient air temperature. The pumped loop cooling system is positioned within the container except for a condenser positioned outside the container. The vapor compression loop system is positioned outside the container and includes a liquid to liquid heat exchanger which cools the fluid in the pumped loop system when the condenser is selectively bypassed when the temperature inside the container is higher than the temperature outside the container.

Abstract: A service valve for a refrigerant system comprising a valve body and a system port. The valve body has at least one fluid passage integrated therein including a longitudinal bore. An orifice is located at one end of the bore. An annular protrusion axially extends from the valve body and is symmetrical about the orifice. A valve seat generally surrounds the orifice. The system port includes a valve stem having a first end, a second end, and a bore integrated within. The stem is axially movable within the annular protrusion between at least a first position in which the orifice is closed when the valve stem first end sealingly abuts the valve seat and a second position in which the orifice is open when the valve stem first end is offset from the valve seat. The valve stem is restricted from moving further away from the valve body by the annular protrusion.

Abstract: An evaporating heat exchanger (12) comprises a multitude of parallel channels (40) extending between vertical header pipes (30,32) and forming flow passages (44) from the inlet chamber (34) and to the outlet chamber (36). A venturi device (50) is positioned within the inlet chamber (34) to ensure even mass distribution of refrigerant to the flow passages (44).

Abstract: A refrigeration capillary tube inside suction tube heat exchanger assembly, including a suction tube whose ends each have a slot with a shaped inner end portion; two braze connectors, each including a sleeve portion with the free end having a shaped recess; a capillary tube adapted to be inserted into one of the suction tube ends and therethrough until each capillary tube ends extends from a suction tube end, each capillary tube end being deformed so as to emerge from the suction tube at locations abutting the shaped inner end portions thereof; and each of the braze connectors sleeve portions engaging one of the suction tube ends, with each suction tube slot cooperating with an adjacent one of the sleeve portion shaped recesses to contact, locate and subsequently fixedly secure the deformed capillary tube portions to the suction tube. Two methods of manufacturing the assembly are also set forth.
