  • Patent number: 6550431
    Abstract: The present invention relates to a method for degassing a cooling system for an internal combustion engine (1), in which a coolant is brought to circulate on the one hand in a cooling circuit between the engine and a radiator unit (2) and on the other between the engine and a bypass circuit, past the radiator unit. The coolant is hereby controlled, in dependence of the temperature, to flow through the cooling circuit and/or the bypass circuit, and the degassing is performed through draining off a limited coolant flow. The degassing is achieved by draining off of a limited portion of that coolant flow which is brought to flow through the bypass circuit, and is thus performed in dependence of the coolant temperature.

This purge tank also has a top chamber which is connected to the bottom chamber through a passageway; and, the bottom chamber is sized such that the liquid coolant passes through it with a velocity which is low enough to let any air bubbles in the coolant rise and move by buoyancy through the passageway into the top chamber. Air is purged from the top chamber through a valved output port by forcing liquid coolant into the top chamber through a valved input port. To complete this purge quickly, the passageway between the purge tank chambers is configured in a way which hinders the flow of coolant from the top chamber to the bottom chamber while the coolant is being forced into the top chamber.

  • Patent number: 4901790
    Abstract: A diffuser unit for allowing non-condensing gases collecting within a heat pipe to be eliminated. The embodiments described herein define a cavity for collection of non-condensing gases such as hydrogen. The housings are arranged such that the heat pipe working fluid in vapor form transfers heat to the walls of the housing defining the collection cavity to raise the wall temperature thus increasing its permeability to the non-condensing gas. Accordingly, when the heat pipe is used in applications where non-condensing gases such as hydrogen tend to diffuse into the heat pipe such as when it is directly heated by a hydrocarbon combustion, such non-condensing gases can be readily eliminated. Such diffusion of non-condensing gases occurs without the requirement of providing a conventional "getter" which uses special material for absorbing or breaking down such non-condensing gases.

    Abstract: A heat pipe comprising a container having water enclosed therein as a working fluid and made of a material reactive with water to evolve hydrogen gas. The heat pipe is characterized in that the container has placed therein a solid oxidizing agent for oxidizing the hydrogen gas to water. The hydrogen gas produced by the reaction of the working fluid, i.e. water, with the container is oxidized to water by the oxidizing agent without remaining in the form of a gas within the condensing portion of the pipe.

  • Patent number: 4781247
    Abstract: A heat exchanger, in the form of a radiator, for the coolant circuit of an internal combustion engine. The radiator has an upper water tank, a lower water tank that is connected to a return line, and heat exchanger tubes that extend between the upper and lower water tanks. For more uniform thermal transmission, an air-withdrawal line extends through the heat exchanger register and the lower water tank into the return line.

  • Patent number: 4753285
    Abstract: A piping installation having a supply header, a return header, and a branch conduit array with parallel branch conduits is provided with a by-pass apparatus to by-pass any trapped air within the piping installation away from the branch conduit array. The by-pass apparatus is connected to the supply header at a position immediate to the supply header end of the downstream-most branch conduit, and to the return header. The by-pass apparatus has a by-pass conduit and an adapter. The by-pass conduit has a length and an inside diameter that presents substantially more resistance to the flow of fluid than to the flow of air. In addition, the length of the by-pass conduit allows the supply header to be properly spaced from the return header so as to minimize thermal interference. An adapter is provided on each end of the by-pass conduit and facilitates the connection of the by-pass conduit to the respective header.

  • Patent number: 4747446
    Abstract: An integrally molded water box (36) and expansion chamber (38) device having a water box (36) with a middle partition (40) dividing it into two compartments, with a liquid inlet fitting (44) opening into the top compartment and a liquid outlet fitting (46) opening out into the bottom compartment. The inlet fitting (44) is located adjacent to the middle partition (40) and is connected to the expansion chamber via an orifice (48) through a wall (50) separating the expansion chamber from the water box, said orifice forming a liquid degassing passage. The invention is applicable to motor vehicle radiators.

  • Patent number: 4738306
    Abstract: An improved horizontal type radiator is disclosed in which the top wall of a header tank, into which a bank of radiator tubes are opened, is externally raised into an annular bulge formed to encircle an upper pipe hole bored in the wall through which a water filling pipe is inserted into the header tank forming an annular space about the inserted lower end of the pipe. Also, the bottom wall of the header tank is outwardly bulged into an annular bulge formed to encircle a lower pipe hole bored in the wall through which a water passage pipe is inserted into the header tank forming an annular space about the inserted end portion of the water passage pipe. With this arrangement, in operation when the water flows from the radiator tubes into the header tank, the water has limited chance of entraining air within the header tank, since the upper annular space in which air may possibly be entrained offers only a minimum contact surface of air with the water.

  • Patent number: 4653577
    Abstract: A compact unitary heat exchanger and debubbler for a liquid includes an elongated heat exchange element having an inverted V-shape and a vertically-extending debubbling chamber located between the legs of the inverted V. The heat exchange element is made up of an inner tube surrounded by an outer tube, so that a heat exchange fluid such as water flowing within the inner tube exchanges heat with a treated liquid flowing within a space defined between the inner and outer tubes. After passing through the heat exchange element the treated liquid passes through the debubbling chamber and then through the device outlet. A bypass passageway in the vicinity of the treated liquid inlet to the device connects the debubbling chamber with the space between the inner and outer tubes of the heat exchange element. A valve movable into open and closed positions is provided in this bypass passageway.

  • Patent number: 4589478
    Abstract: A heat exchanger of the tube and shell type comprising a shell and a shell enclosed tubular core, the core being removable from the shell for inspection and servicing. Motion of the core relative to the shell, and motion of core components relative to one another, is precluded without loss of core access and removability. In one disclosed form of the invention, abutments, at least one of which is part of a detachable closure, limit endwise core motion as well as a relative separating motion of headers which, together with interconnecting tubes, make up a core assembly. At the same time a rigid interponent element limits a relative approaching motion of the headers. In another disclosed form of the invention, headers have a screw threaded connection to parts of the enclosing shell.
