20130206376 | HEAT EXCHANGER, REFRIGERATION CYCLE DEVICE EQUIPPED WITH HEAT EXCHANGER, OR HEAT ENERGY RECOVERY DEVICE - A plurality of heat-exchanger tubes, each of which has an inlet fin formed on a side surface on the air inlet side of a flattened hollow tube and extending upstream of air along the flow of air and an outlet fin formed on the side surface on the air outlet side of the hollow tube and extending downstream of the air along the flow of the air are arranged at regular intervals in such a manner that their oblong planes face one another, an upper header which supplies a first heat exchange medium is attached on top of the heat-exchanger tubes, and an lower header which collects the first heat exchange medium is attached at the bottom of the heat-exchanger tubes to form a heat exchanger. | 08-15-2013 |

20100251702 | Heat Recovery System - A plurality of flat tubes formed as a tube having notches by linearly cutting upper and lower parts from a hollow flat circular doughnut shape are stacked to structure a tube laminate. It is attached to a case so that a notch aligns with the notch and faces upward by an exhaust inflow end plate and that a notch aligns with the notch and faces downward by an exhaust outflow end plate. A cutoff valve is provided at an exhaust outflow end of an exhaust communication tube passing through the center of the tube laminate by heat insulation. While an internal combustion engine is warming up, the cutoff valve is closed to cause the exhaust to flow in gaps of the respective flat tubes from upward to downward as a whole and also a heat exchange medium is caused to flow in the respective flat tubes from downward to upward as a whole to have heat exchanged between the exhaust and the heat exchange medium to recover the exhaust heat. | 10-07-2010 |
