Abstract
An assembly for changing the temperature of ultrahigh-pressure fluid as it flows through ultrahigh-pressure tubing includes several thermally conductive blocks. Each block has a first bore through which the ultrahigh-pressure tubing passes, and a second bore containing a source of heating or cooling. Alternatively, resistance heating is used to increase the temperature of the ultrahigh-pressure fluid, by coupling electrodes to the outer surface of the tubing. The ultrahigh-pressure fluid is heated or cooled after it is pressurized, and is then discharged from the ultrahigh-pressure tubing at a selected temperature for use. For example, the ultrahigh-pressure fluid at a selected temperature may be discharged through a nozzle to form an ultrahigh-pressure fluid jet to cut or clean any desired surface or object, or it may be discharged to a pressure vessel to pressure treat a substance.
