Abstract
A surge tank comprises a liquid inlet portion designed to dissipate the energy of coolant flowing into the surge tank. Desirably, fluid is delivered into a pool of liquid in an initial chamber rather than into an air gap above a pool of liquid such that the pool of liquid assists in dissipating energy of the entering coolant. Coolant from the last of a series of initial chambers desirably exits in a manner that reduces the distance air bubbles must rise to separate from the coolant. Also, when coolant flows from one initial chamber to at least one other initial chamber, desirably the direction of flow of at least a major volume of the coolant is changed, such as by locating an outlet passage from one chamber at a lower portion thereof and the passage from a subsequent chamber at an upper portion thereof. Passageways between the various chambers may be of a progressively increasing total cross-sectional area to assist in reducing the velocity of fluid flow from one chamber to the next. Also, in desirable embodiments, substantially laminar coolant flow is achieved prior to passage of coolant from an exiting chamber into a primary coolant receiving section of the surge tank.
