Abstract
An heat exchanger apparatus mounted in a closed volume, such as a vehicle overflow tank or vehicle radiator, includes a rotating member divided internally by a stationary disk, with the interior of the rotating member and the disk connected in fluid flow communication with a refrigerant to enable the rotating member to act as a heat sink to sweep condensate back into the surrounding closed volume tank or radiator. The rotating member is rotated at a constant speed to provide a specified heat exchange capacity to enable the engine to operate for extended periods without use of the main heat exchanger or radiator.
Claims13
An auxiliary heat exchange apparatus for removing waste heat from a two phase fluid circulating in a movable heat generating apparatus having a primary heat exchanger, the auxiliary heat exchange apparatus comprising:
- a closed volume receiving heated two phase fluid and having a liquid containing portion disposed in fluid flow communication with a vapor receiving portion;
- a rotating member disposed in the vapor receiving portion of the closed volume, the rotating member having a hollow interior and rotating about a substantially vertically extending axis;
- a stationary disk mounted within the interior of the rotating member;
- a first conduit connected to the disk and opening at one end through the disk.
- a second conduit connected to the rotating member;
- the first and second conduits forming a closed path for a coolant circulating about the disk through the interior of the rotating member enabling the rotating member to act as a heat sink to condense vapors of the two phase fluid to condensate on outer surfaces of the rotating member, whereby the rotating member sweeps the condensate through centrifugal force from the outer surfaces of the rotating member for flow into the liquid containing portion of the closed volume;
- and
- a baffle having a plurality of spaced apertures mounted in the closed volume below the rotating member between the liquid containing portion and the vapor receiving portion of the closed volume.
