Patent ID: 8794820

Claim:
An apparatus for the heat exchanging and mixing treatment of fluid media comprising a housing disposed on a longitudinal axis; a first hollow structure disposed in said housing longitudinally of said axis for the passage of a first fluid therethrough and the passage of a second fluid thereover, said first hollow structure including at least two parallel tubes disposed adjacent each other to form a single flow obstruction to the second fluid with one of said tubes communicating with another of said tubes to convey the first fluid therethrough; and a second hollow structure disposed in said housing in communication with said first hollow structure for the passage of the first fluid therethrough and the passage of the second fluid thereover, said second hollow structure including at least two parallel tubes disposed adjacent each other to form a single flow obstruction to the second fluid with one of said tubes communicating with another of said tubes to convey the first fluid therethrough; said first hollow structure and said second hollow structure being arranged cross-wise with respect to one another, each said hollow structure having a flow cross-section with a first width B 1 and a second width B 2 perpendicular to said first width B 1 , with B 1 /B 2 being larger than one and B 1 oriented normally to a first plane containing said longitudinal axis of said housing, and each said hollow structure having at least one section extending at an angle towards a second plane perpendicular to said first plane and containing said longitudinal axis of said housing for deflecting the second fluid thereover and at least one section extending at an angle away from said second plane for deflecting the second fluid thereover.
