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.
Claims20
A freeze damage resistant thermal energy heat exchanger comprising:
- a finless, thin walled hollow tubular shell having a proximate end and a distil end, and defining a first fluid chamber;
- at least two end caps, each affixed at either said proximate or said distal end of said shell;
- at least one inlet fitting into said first fluid chamber;
- at least one shell outlet fitting out of said first fluid chamber;
- a thermally insulated core tube residing within said shell and defining a second chamber;
- at least one core tube inlet fitting into said second chamber;
- at least one core tube outlet fitting out of said second chamber;
- and
- a spiral baffle with a linear bore formed about a longitudinal axis thereof said baffle,
- wherein said baffle resides within said shell with said core tube passing through said bore, and
- wherein there is a spatial gap between said core tube and said baffle;
- and
- wherein said core tube can elastically deform and alter its shape to accommodate volume changes within said first fluid chamber or second chamber.
A freeze damage resistant heat exchanger comprising:
- a heat exchanger body;
- a heat transfer surface on the outside of said heat exchanger body;
- a heat transfer first fluid passing through said heat exchanger body;
- an elastically deformable thermal barrier within said heat exchanger body;
- a second fluid passing through said thermal barrier;
- and
- wherein said thermal barrier resides between said first fluid and said second fluid and prevents the transfer of thermal energy between said fluids, and wherein said thermal barrier can elastically deform and alter its shape to accommodate volume changes within said heat exchanger due to the freezing of either said first fluid or said second fluid.
A heat exchanger with mechanical freeze damage protection comprising:
- a finless, thin walled hollow tubular shell having a proximate end and a distil end, and defining a first fluid chamber;
- at least two end caps, each affixed at either said proximate or said distal end of said shell;
- at least one shell inlet fitting into said first fluid chamber;
- at least one shell outlet fitting out of said first fluid chamber;
- a mechanical freeze protection thermal barrier traversing between said distil and proximate ends of said shell and defining a second fluid chamber;
- at least one inlet fitting into said second fluid chamber;
- at least one outlet fitting out of said second fluid chamber;
- a spiral baffle with a longitudinal bore formed there along, wherein said baffle resides freely within said shell retaining a spatial gap between said shell and said thermal barrier;
- at least one core tube inlet fitting into said second fluid chamber;
- at least one core tube outlet fitting out of said second fluid chamber.
