Title (EN) METHOD AND APPARATUS FOR FLUID TEMPERATURE CONTROL
(FR) PROCEDE ET DISPOSITIF SERVANT A REGULER LA TEMPERATURE D'UN LIQUIDE
Abstract:
(EN) An apparatus and method for cooling or heating fluids, as fuel in a fuel system of an automotive vehicle. Compressed gas is delivered to a vortex tube or air amplifier (14) so that the gas rapidly expands and cools, thereby cooling a first end (16) of the vortex tube (14) in relation to a warmer second end (18) thereof. A first fuel inlet port (20) of a first heat exchanger (16) lies proximate the first end (16) so that fuel flowing into the inlet port (20) is cooled by thermal contact with the first end (16) of the vortex tube (14). A cooled fuel outlet port (22) in the heat exchanger (16) lies proximate the first end (16) so that cooled fuel may leave the heat exchanger (16) for delivery to an engine. A valve with an upstream gate (26) and two downstream gates (28, 30) is located so that fuel is selectively delivered to the first fuel inlet port (20) and one of the two downstream gates (28, 30).
(FR) Dispositif et procédé servant à refroidir ou à réchauffer des liquides, tel que le carburant dans un système de distribution de carburant de véhicule automobile. Du gaz comprimé alimente un tube à tourbillons ou un amplificateur d'air (14), de sorte que le gaz se dilate et se refroidit rapidement, ce qui refroidit une première extrémité (16) du tube à tourbillons (14) par rapport à sa deuxième extrémité (18) plus chaude. Un premier orifice d'entrée de carburant (20) d'un premier échangeur de chaleur (16) est situé à proximité de la première extrémité (16), de sorte que le carburant pénétrant dans l'orifice d'entrée (20) est refroidi par contact thermique avec la première extrémité (16) du tube à tourbillons (14). Un orifice de sortie de carburant refroidi (22) dans l'échangeur de chaleur (16) est situé à proximité de la première extrémité (16), de sorte que le carburant refroidi peut quitter l'échangeur de chaleur (16) afin d'alimenter un moteur. Une soupape comportant un corps amont (26) et deux corps situés en aval (28, 30) est positionnée de telle façon que le carburant alimente sélectivement le premier orifice d'entrée de carburant (20) et un des deux corps situés en aval (28, 30).
