The jacketing system seals around the material-carrying tube and allows a thermal transfer fluid to be circulated in the resulting annular space so as to change the temperature of the material being dispensed. Because the system is comprised of a series of tubing and hoses it is flexible and can be routed around corners and through wire tracks and can be used in both manual and robotic applications. Because the seals around the material-carrying tube can be released and subsequently re-sealed, the internal material-carrying tube can be replaced, defined as “re-coring” the hose assembly.

The heated fluid is then radially disbursed as it converges toward the internal surface of a top cover of the heat exchanger assembly, being forced outwardly under the top flange by the updraft force of the heated fluid, which forces the heated fluid downwardly apportioning the heated fluid around equally spaced axially arranged heat transfer tubes surrounded by an outer tube which are in sealed engagement with the top flange and attach at the bottom in sealing engagement with the exhaust collection manifold. The heated fluid descends around the tubes and enters an exhaust manifold exiting through an exhaust pipe.

  • Patent number: 9488081
    Abstract: An exhaust runner includes an exhaust runner inlet, an exhaust nozzle outlet aperture, and an impingement insulator. The exhaust runner inlet is configured to receive a first flow of an exhaust gas from an internal combustion engine. The exhaust nozzle outlet aperture is defined by an intersection of a tip flow passage and an internal surface of the exhaust runner. The exhaust nozzle outlet aperture is configured to introduce a second flow of the exhaust gas into the first flow of the exhaust gas. An impingement zone is defined by a projection of the outlet aperture onto the internal surface of the runner in a direction of the second flow of the exhaust gas. The impingement insulator is collocated with the impingement zone.

  • Publication number: 20150068716
    Abstract: An exhaust gas heat exchanger, in particular for use in a motor vehicle, having at least one first flow channel that conducts a first fluid, which first flow channel is accommodated in respective tube sheets at end areas of the first flow channel. A housing surrounds the first flow channel and forms a second flow channel for a second fluid that flows through the housing and flows around the first flow channel. Pipe sheets are inserted into the housing such that the first flow channel is sealed off from the second flow channel. A first diffusor conducts the first fluid into the first flow channel and a second diffusor conducts the first fluid out of the first flow channel. A first shielding element has a first passage and a first spacing element is placed onto a tube sheet from the side facing away from the first flow channel.

  • Patent number: 8925620
    Abstract: A windshield washer fluid heater for an automotive vehicle has an elongated housing with two open ends and in which the housing defines a housing chamber. A tubular subhousing divides the housing chamber into an outer housing chamber and an inner housing chamber. A core is disposed in the inner housing chamber and this core forms an annular chamber between the core and the subhousing. A pair of end caps is attached to the ends of the housing and these end caps sealingly engage the housing and the subchamber to fluidly separate the outer housing chamber from the annular chamber. The housing includes a washer fluid passageway which fluidly connects a washer fluid port on the end cap with the annular chamber as well as a coolant fluid passageway which fluidly connects a coolant port on each end cap with the housing chamber.
