  • Patent number: 9689620
    Abstract: Disclosed is a heat exchanger that can more efficiently transfer heat between a heat-exchange fluid and an object with which heat is to be exchanged. A heat exchanger (1) can transfer heat between a heat-exchange fluid flowing through flow paths (R1) and a fluid with which heat is to be exchanged flowing through other flow paths (R2) by means of the flow path structure member (10) (a first metal sheet (11) and a second metal sheet (12)) in which the flow paths (R1 and R2) are formed. The flow paths (R1 and R2) are formed so that the side surfaces thereof are not straight and so that the depths thereof change along the flow direction.

    Abstract: A reactor using honeycomb catalyst is provided for fuel reformation with high activity and heat stability. The reactor comprises a heating tube, a methane gas inlet, a three-way steam inlet and a hydrogen-rich gas outlet. The three-way steam inlet is near to the heating tube for providing heat required for reformation and to reduce power consumption. The heating tube is made of an inconel material so that the overall reaction may be carried out at high temperature. The heating tube is set with a honeycomb carrier of cordierite. The honeycomb carrier is pasted with carbon nanotube and heat-treated to increase internal surface area. The honeycomb carrier has a Pt/CeO2/?-Al2O3 catalyst; is placed in the heating tube; and has honeycomb-pores channels parallel to a main axis of the heating tube.

  • Patent number: 9097472
    Abstract: A fin member for a heat exchanger is produced by repeatedly folding a plate over itself into a corrugated shape to form corrugated fins. The folded sections which are formed by the folding are pressed and deformed into a recessed shape to form engagement recesses. A pipe member through which fluid flows is disposed at the engagement recesses. The pressing and deformation of the engagement recesses cause swollen sections to protrude at both sides of each folded section with respect to the folding-over direction of the folded section and form flat butt surfaces at the tips of the swollen sections. Adjacent butt surfaces are caused to be in surface contact with each other with the pipe member disposed at the engagement recesses.

  • Publication number: 20140231058
    Abstract: A guide plate having depressed portions is provided between an array of heat exchanger tubes, herein after “tubes”, arranged horizontally side-by-side and a next lower array of tubes arranged horizontally side-by-side, and is positioned with the lowest parts of the depressed portions near crest portions of respective lower tubes. The guide plate conveys a liquid D on outer surfaces of respective upper tubes onto similarly positioned lower tubes even when the tubes move in a right-and-left direction. A falling film heat exchanger installed in a ship, an offshore structure or the like can avoid reduction in heat exchange performance, even when the ship or the like inclines and swings, by substantially evenly distributing and dropping a liquid onto the crests of the tubes and causing the liquid dropped from the tubes located in an upper array to fall onto the tubes located in the next lower array.

  • Patent number: RE45113
    Abstract: A melt cooler and valving system for an underwater pelletizer has a diverter valve that facilitates multiple modes of melt processing. The cooler has a cooler inlet line that conveys the melt to the cooler, and a cooler outlet line that conveys the cooled melt from the cooler. The diverter valve is configured to convey the melt to and from the cooler during a cooling mode of operation, to convey the melt around the cooler during a bypass mode of operation, and to drain the melt from the cooler and the diverter valve during a drain mode of operation. The diverter valve is compact and therefore contains a minimum of product inventory. The valve is streamlined and direct in its bypass mode, and includes a drain capability to allow for faster, easier cleaning of the process line, which in turn provides a fast changeover time with less lost product.
