摘要： A heat exchanger assembled from multiple heat exchanging tubes. Each of the multiple heat exchanging tubes is formed as a flattened tube of 0.5 mm in thickness by press work or bending work of a stainless steel plate member having a thickness of 0.1 mm. Each of the multiple heat exchanging tubes is structured to have multiple lines of sequential wave crests and multiple lines of sequential wave troughs formed on each of flattened faces of the heat exchanging tube. The multiple lines of the sequential wave crests and the multiple lines of the sequential wave troughs are arranged to have a preset angle γ relative to a main stream of an air flow. The lines of the sequential wave crests and the lines of the sequential wave troughs are symmetrically folded back about folding lines arranged at a preset interval W along the main stream of the air flow.

摘要： A flat tube includes pairs of dimple portions in a longitudinal direction thereof. Each of the pairs has a first dimple portion and a second dimple portion, which are slanted with respect to an intermediate line extending in the longitudinal direction at an intermediate position in a lateral direction so that inner end wall portions of the first and second dimple portions are located on the intermediate line, and so that the outer end wall potions thereof depart from the intermediate line in the lateral direction to be toward outer sides of the tube, respectively. The pairs of dimple portions are set to satisfy a relationship expressed by an inequality: 3≦L2/L1≦12, where L1 is a longitudinal projection length obtained by projecting one of the first and second dimple portions on the intermediate line, and L2 is a longitudinal pitch between adjacent pairs.

摘要： 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.

摘要： An impeller in a water pump for circulation of cooling medium in a cooling system of an engine has a shroud with a shroud end to which the edges of the blade inlets are attached and which is formed in the cylindrical configuration substantially parallel to the rotary shaft. Each of the edges of the blade inlets is shaped so that it is continuously smooth from a shroud end surface at the inlet side thereof and extends upstream in the axial direction, while each of the edges of the blade inlets at the side of a casing extends substantially perpendicularly to the rotary shaft. The edge of the blade inlet attached to the cylindrical shroud end and the edge of the blade inlet at the casing side being connected therebetween by a smooth arc-like curve projecting convexly upstream. The inlet angle of the blade is set to substantially 0.degree. at the inlet edge at the shroud end and to an angle calculated substantially on the basis of the conventional design at the inlet edge at the casing side. The impeller has the blades each formed by connecting the blade inlet to a blade outlet by a smooth curved surface.
