ABSTRACT:
A vessel-type fluid cooling system includes an upper mixing chamber and a lower holding chamber, the chambers being separated by a transverse separating wall. One or more cooling tubes extend between the mixing chamber and the holding chamber, and cooling elements, such as fluid-cooled tubes, are located within each cooling tube. A heated fluid inlet provides heated fluid to the mixing chamber, and a cooled fluid outlet discharges cooled fluid from the holding chamber. Each cooling tube includes one or more inlets toward its upper end, and fluid is supplied from the mixing through the inlets to passages defined by the cooling tubes for cooling the fluid as the fluid flows downwardly through the cooling tubes. The cooled fluid is discharged into the holding chamber. Flow of cooled fluid through the cooling tubes functions to pre-cool fluid contained within the mixing chamber, so that fully heated fluid is not exposed directly to the cooling elements, thereby avoiding flashing of the fluid which otherwise may occur.
