    • An apparatus and method for cooling or heating fluids, such 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 thereof 18. 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 through the upstream gate 26 and one of the two downstream gates 28,30 if cooling of the fuel is desired. The second downstream gate 30 is connected to a second fuel inlet port 34 in a second heat exchanger 18 so that fuel flowing therethrough is warmed thereby if heating of the fuel is desired. A warmed fuel outlet port 36 is provided in the second heat exchanger so that warmed fuel may leave the second heat exchanger 18. A temperature sensor 40 and valve controller are in communication with the valve.
    • 一种用于冷却或加热流体的装置和方法,例如在机动车辆的燃料系统中的燃料。 压缩气体被输送到涡流管或空气放大器14,使得气体快速膨胀和冷却,从而相对于其较暖的第二端18冷却涡流管14的第一端16. 18.一种第一燃料入口 第一热交换器16位于第一端16附近,使得流入入口20的燃料通过与涡流管14的第一端16的热接触而被冷却。热交换器16中的冷却燃料出口22靠近第一 使得冷却的燃料可能离开热交换器16以输送到发动机。 具有上游门26和两个下游门28,30的阀被定位成使得如果燃料冷却是通过上游门26和两个下游门28,30中的一个选择性地将燃料输送到第一燃料入口20 想要的 第二下游门30连接到第二热交换器18中的第二燃料入口端口34,使得流过其中的燃料由此被加热,从而需要加热燃料。 在第二热交换器中设置一个加温燃料出口36,使得加热的燃料可以离开第二热交换器18.温度传感器40和阀控制器与阀连通。
