Abstract
A room perimeter heating/cooling radiator with a non symmetrical elliptical transverse cross section, that utilizes low to medium temperature heat transfer fluid (generally water or water/glycol) in a new design with an enhanced ‘primary only’ heat transfer surface having an internal spiral or helix to circulate the water around the inside of the primary surface to enhance the heat transfer, and an internal conduit that provides both freeze damage protection and the ability to cross connect multiple identical radiators for increased efficiency. The primary intended location is within inches of the building windows.
Claims9
A freeze damage resistant heat exchanger comprising:
- a shell;
- a heat transfer surface on the outside of said heat exchanger body;
- a heat transfer first fluid passing through said shell, said fluid having a volume;
- an elastically deformable thermally insulated core tube within said shell, said core tube fabricated from a cross-linked high density polyethylene, said core tube having a wall thickness between 10% and 13% of a diameter of said core tube capable of an elastic deformation to accommodate up to a 7% increase in said volume;
- a second fluid passing through said core tube;
- and
- wherein said core tube resides between said first fluid and said second fluid and minimizes the transfer of thermal energy between said fluids, and wherein said core tube can elastically deform and alter its own shape to accommodate volume changes within said heat exchanger due to the freezing of either said first fluid or said second fluid.
