Distribution case's cover for e.g. engine cooling radiator, in motor vehicle, has manifold assuring flow of heat transfer fluid in downstream of main deflector arranged in volume, where main and auxiliary deflectors are arranged in chute

摘要

#CMT# #/CMT# The cover (1) has a fluid inlet and outlet manifold (100) opening in a volume defined by a distribution case. A bidirectional main deflector (25) is arranged in the volume, and the manifold assures a flow of heat transfer fluid in downstream of the deflector. Auxiliary deflectors (26) are respectively arranged on two sides of the opening of the manifold. The main and auxiliary deflectors are arranged in a chute (200) of the cover for assuring a laminar flow of the fluid in two reverse direction channels. Tubes received by a collector plate are opened in the volume. #CMT#USE : #/CMT# Cover for a distribution case of a tube type heat exchanger (all claimed) e.g. engine cooling radiator, of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The bidirectional main deflector allows the utilization of the cover at the inlet and the outlet of the heat exchanger. The main and auxiliary deflectors are arranged in the chute of the cover for assuring the laminar flow of the fluid in two reverse direction channels, thus ensuring better cooling of the engine of the vehicle. The deflectors reduce the speed of the fluid and avoid wear and tear of the heat exchanger tubes arranged near the manifold, thus reducing the risk of fluid leakage due to hydrodynamic degradations subjected by the tubes, and avoiding a turbulent flow in the exchanger when the manifold is moved with respect to the center of the cover. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a cover. 1 : Cover 25 : Bidirectional main deflector 26 : Auxiliary deflectors 100 : Fluid inlet and outlet manifold 200 : Chute.
