Abstract: Embodiments disclose a flexible connection of a metallic extruded profile to a connecting body for cooling electrical components. A heat exchanger for an electrical component comprises a metallic extruded profile having at least one channel for a cooling agent to flow through, the metallic extruded profile including an outer circumferential surface and a first end, a non-metallic connecting body including an accommodating region for receiving the first end of the metallic extruded profile at a first opening corresponding to a cross-section of the first end, the first opening having an inner circumferential surface, and a bonding layer between the outer circumferential surface of the first end received in the accommodating region and the inner circumferential surface of the opening. The bonding layer is configured to establish a mechanically flexible bond between the metallic extruded profile and the non-metallic connecting body. Embodiments further disclose a production method for a heat exchanger.

Abstract: Asynchronous digital circuits are described, including arbitration and routing primitives for asynchronous and mixed-timing networks. An asynchronous arbitration primitive has two data inputs and one data output. A mutual exclusion element is used to select the first-arriving data request from one of the two inputs to the output. A asynchronous routing primitive has one data input and two data outputs. The incoming data is routed to one of the two outputs based on a routing bit accompanying the data. The primitives use handshaking with request and acknowledge signals to ensure that data is passed when neighboring circuits are ready to receive or send data.

Abstract: A fuel supply system for a marine propulsion system having an electronically controlled fuel injection system eliminates the need for a vapor separator. The system pumps an excessive amount of fuel through a plumbed fuel supply loop and cools recirculated fuel to cool all the components in the plumbed fuel supply loop, i.e. a continuous duty, constant displacement fuel pump; a pressure regulator; and a water separating fuel filter. Recirculated fuel flows from the pressure regulator to the water separating fuel filter as does make-up fuel from a fuel tank. The fuel stream from the water separating fuel filter flows to the low-pressure side of the fuel pump, which pumps the fuel through the plumb fuel supply loop. A fuel injection portion of the fuel flows to the engine for combustion, while the remaining portion of the fuel is recirculated. The recirculated portion of the fuel is cooled, preferably using a water-cooled heat exchanger.

Abstract: A heat exchanger assembly is provided for a marine propulsion system having a closed loop cooling system. The heat exchanger body encloses a series of tubes carrying sea water which removes heat from the engine coolant. The heat exchanger includes an integrally connected top tank. A single venting orifice is provided into the top tank from the heat exchanger body. A heat exchanger coolant outlet is in direct fluid communication with both a system bypass and the coolant in the top tank. An auxiliary inlet for coolant from the top tank is located in the heat exchanger coolant outlet downstream of the bypass inlet, thereby promoting the ability of the system to draw coolant through the top tank rather than the bypass. The invention minimizes cavitation and reduces the creation of negative pressure at the circulating pump.
