Abstract
A heat exchange apparatus in which each of a plurality of thermal siphon pipes has an upper portion extending in an upper heat exchange section and a lower portion extending in a lower heat exchange section. Each pipe is closed at its ends and contains a heat transfer fluid so that when a hot fluid is passed through the lower heat exchange section, the heat is transferred from the hot fluid to the heat exchange fluid. A cool fluid is passed through the upper heat exchange section to remove the heat from the heat exchange fluid.
Claims9
A heat exchange apparatus comprising a plurality of heat exchange sections, partition means for dividing each section into an upper portion and a lower portion, additional partition means for dividing the upper portion of each of said sections into a plurality of horizontally aligned compartments, a plurality of thermal siphon pipes each having an upper portion extending into said compartments and a lower portion extending into said lower portion of said section, each of said pipes being closed at each end and containing a heat exchange fluid, means for connecting the lower portion of said sections to a source of relatively hot fluid so that said hot fluid passes across said lower portions of said pipes to transfer heat from said hot portion to said heat exchange fluid, fan means associated with each compartment for passing relatively cool ambient air across said upper portions of said pipes to remove heat from said heat exchange fluid, an outlet for exhausing said air to the atmosphere after it has passed over said upper portions of said pipes, and an additional outlet for passing said air to a collection duct for further treatment after the air has passed over said upper portions of said pipes.
A heat exchanger for exchanging heat energy from a relatively hot fluid to a relatively cooler fluid comprising:
- a heat exchanger housing defined by top, bottom and side walls, a partition dividing the interior of said housing into an upper portion and a lower portion, a plurality of thermal siphon pipes extending through said partition with their respective evaporator sections located in said lower portion and their respective condenser sections located in said upper portion, a plurality of panels internal to said upper portion dividing the upper portion into a plurality of heat transfer compartments and adjacent cooling fluid plenums, said compartments substantially enclosing the upper portions of some of said thermal siphon pipes, the panel dividing each compartment from its respective plenum provided with means to substantially uniformly distribute the flow of a cooling fluid from said plenum into said compartment, each compartment provided with an outlet to exhaust the cooling fluid after it has passed over the condenser section of said thermal siphon pipes, means for introducing a flow of cooling fluid into each of said plenums and through said inlet opening to cool said condenser sections of said heat pipes.
