摘要： A method for manufacturing a heat exchanger includes stacking a plurality of parting sheets, a plurality of lengthwise closure bars, and a plurality of widthwise closure bars to form a rectangular first heat exchanger section. The first heat exchanger section includes at least one widthwise passage extending between a pair of the widthwise closure bars and at least one lengthwise passage extending between a pair of the lengthwise closure bars. The method also includes brazing the rectangular first heat exchanger section together and cutting a first side and a second side of the rectangular first heat exchanger section to give the first heat exchanger section a tapered-trapezoid profile. The method further includes brazing an end of a second heat exchanger section to the first or second side of the first heat exchanger section.

摘要： Disclosed is a barrel-shaped component and a container and an electric motor housing based thereon. The barrel-shaped component comprises a hollow metal pipe (11), wherein two ends of the hollow metal pipe (11) are respectively provided with an inlet (12) and an outlet (13). The hollow metal pipe (11) continuously spirals around an axis to form a plurality of annular components (14) arranged in parallel, wherein the annular components (14) are welded and fixed to each other. A component of any shape and size can be processed by using a simple elbow mould, thereby improving the cooling effect, lowering the processing cost and the material cost, and increasing the rigidity of the whole component where the barrel has the same wall thickness.

摘要： It is known that corrugated plate heat exchangers can have good thermal and hydraulic performance but limitations with regard to operational pressures whilst conventional tube type heat exchangers can achieve high pressure operation but can have high flow pressure losses due to the configuration of such tubes. By arranging a tube stack comprising respective tubes 2a, 3a arranged in layers typically one upon the other with cross junctions 4 between them and interstitial gaps between tubes it is possible to create swirling spinning motion in the flow possibly inside and at least outside the tubes for improved heat exchange with only limited flow restriction. The swirling flow in the heat exchanger matrix outside of the tubes passes along channels formed by the interconnecting interstitial gaps between the tubes and is guided about those tubes for heat exchange. Typically, a multitude of stack layers is combined such that association between the stack layers prevents in operation lateral and vertical movements as well as vibration of the tubes.

摘要： A heat exchanger for use with exhaust pipes. A shroud inlet communicates with a rear chamber, which communicates with a front chamber via a center plate vent. The front chamber communicates with a shroud outlet. Ambient air entering the rear chamber is routed around at least one J-pipe in the rear chamber, and around a collector in the front chamber, thus being twice heated prior to exiting the heat exchanger through the shroud outlet. The double heating provided by this design increases the efficiency of the heat exchanger. The collector is attached to the center plate by means of a full-penetration fillet weld, and the J-pipes are attached to the center plate, a front plate, and a pipe assembly baffle by stitch welding external to the J-pipes, thus strengthening the integrity of the hermetic seal between exhaust gasses and ambient air passing through the heat exchanger.

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： A vapor generator comprising an evaporator unit, which in turn includes an inner chamber for containing a first fluid in a liquid state, and further includes a preheated liquid inlet and a vapor outlet, the evaporator unit having a heating device therein which can be activated for vaporizing the first fluid contained in the inner chamber to generate vapor. The vapor generator further comprises a preheating tank defining an inner chamber and comprising a liquid inlet for injection of the first fluid in a liquid state in the inner chamber, and a liquid outlet. Moreover, the vapor generator comprises an opened liquid channel connecting the preheating tank liquid outlet to the evaporator unit liquid inlet, and establishing free and continuous fluid communication between the preheating tank inner chamber and the evaporator unit inner chamber. The first fluid in a liquid state injected through the preheating tank liquid inlet is continuously distributed between the evaporator unit inner chamber and the preheating tank inner chamber through the liquid channel, and the heating device of the evaporator unit can be activated for generating a temperature gradient across the liquid-state first fluid contained in the evaporator unit inner chamber, the liquid channel and the preheating tank inner chamber, the first fluid being thereby gradually preheated while it circulates from the preheating tank through the liquid channel and into the evaporator unit for being vaporized therein.
