Heat-Exchange Apparatus

摘要

A heat exchanging device has a single extruded part made as a tubular body with external and internal radial branches. The tubular body has longitudinal round holes in a circumferential direction. At least one mount is on the outer surface of the tubular body. Internal and external radial branches taper from the base to the edge of branches and are made sinusoidal with a constant step and amplitude. They can be of the same width from the base to the edge of branches. The sinusoids of external radial branches can be of a variable amplitude and step from the base to the edge. The external radial sinusoidal branches can be of a different length relative and at different distances from each other. The radial branches can be have additional undulating projections. The round holes are made along the entire circumference of the body at equal distances from each other.
