#CMT# #/CMT# The exchanger has tubes (1) superposed on each other, where each tube has partly a helical spiral shape. The tubes have an angular difference between them. The axis of one tube is oriented along a direction at the level of an axis while the axis of another tube is, at the level of another axis, oriented along another direction, where the directions are connected in a same plane presenting the angular difference. #CMT#USE : #/CMT# Heat exchanger e.g. tube exchanger and plate exchanger, for an aircraft to test an engine e.g. aircraft engine. #CMT#ADVANTAGE : #/CMT# The exchanger cools an extremely hot gas from the engine without necessitating a preliminary water injection and permits high stirring of the gas and increased accessibility to each of the tubes, thus permitting to change the tube in an easy and rapid manner irrespective of the position of the tube without damaging the tube. The exchanger permits to totally eliminate the corrosion. The angular difference homogenizes the temperature of the hot air during its usage while ensuring an efficient cooling of the tubes. The exchanger permits the tubes to be replaced easily. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a front view of a tube bundle integrated to the interior of a grill to form a heat exchanger. 1 : Tubes 2, 3 : Tubular units 12 : Grill 13 : Flanges 14 : Fluid supply tube.
