20140345578 | Inner Fin - There is provided an inner fin wherein: a sheet material is formed into an offset configuration in which grooves and ridges are formed alternately in a widthwise direction, and the grooves and the ridges are offset laterally at right angles to a gas flowing direction at predetermined length intervals in an alternate fashion; and a first projection and a second projection are formed for each segment surrounded by a pair of left and right side walls, by cutting either an upper surface portion or a lower surface portion and causing the cut surface portion to stand, the first projection being inclined towards an upstream side of the gas flowing direction, the second projection being disposed downstream of the first projection and being inclined towards a downstream side of the gas flowing direction at an angle equal to an angle at which the first projection is inclined. | 11-27-2014 |
20140326198 | Engine Cooling Apparatus and Engine Cooling Method - A sub-control valve is provided which detects a temperature of a liquid coolant in a main circulation path and separates part of the liquid coolant which is to be sent to a main radiator to send it into a sub-circulation path in case the detected temperature of the liquid coolant exceeds an upper limit value of the temperature of the liquid coolant when an engine runs in a steady state, and the liquid coolant which is sent into the sub-circulation path by the sub-control valve is cooled in a sub-radiator and is then caused to flow into a cooler device, while the liquid coolant in the sub-circulation path is separated to be returned to an upstream side of a first pump in the main circulation path. | 11-06-2014 |
20140318109 | EGR Cooler - There is provided an EGR cooler having a core portion in which a large number of flat tubes through which exhaust gases pass are stacked one on another in an interior of a hollow cylindrical shell to be joined to the shell for heat exchange between the exhaust gases and a cooling fluid which flows around the tubes, a cylindrical inlet header which is joined to an upstream side of the shell in relation to a gas flow at one end thereof, and a cylindrical outlet header which is joined to a downstream side of the core portion in relation to the gas flow at one end thereof, characterized in that the inlet header and the outlet header are joined to an outer surface of the shell, and the tubes are joined to an inner surface of the shell at those joint portions. | 10-30-2014 |
