Abstract
The heat exchanger is constituted by a stack of blocks forming the heat-exchanger body and the connecting end components, ducts for the circulation of primary and secondary fluids being bored in the blocks. Each end block has at least two surfaces which are inclined with respect to each other and into which open the primary and secondary ducts respectively. The surfaces are joined together and support a member which provides a separation between the primary and secondary fluids.
Claims9
A heat exchanger for the convection of heat between primary and secondary fluids circulating through the exchanger, comprising:
- at least one heat exchange block having first and second parallel planar surfaces;
- a first end member having a planar surface in sealing contact with said first parallel planar surface of said heat exchange block, and first and second inclined transverse surfaces opposite said planar surface;
- a second end member having a planar surface in sealing contact with said second parallel planar surface of said heat exchanging block, and first and second inclined transverse surfaces opposite said planar surface;
- means on said first end member separating said first inclined surface from said second inclined surface for forming a primary collecting duct associated with said first inclined surface and for forming a secondary collecting duct associated with said second inclined surface;
- means on said second end member separating said first inclined surface from said second inclined surface for forming a primary collecting duct associated with said second inclined surface and for forming a secondary collecting duct associated with said first inclined surface;
- first channel means for conducting primary fluid from said primary collecting duct of said first end member through said heat exchange block to said primary collecting duct of said second end member;
- and
- second channel means disposed in a heat convecting relationship with said first channel means and for conducting secondary fluid from said secondary collecting duct of said first end member through said heat exchange block to said secondary collecting duct of said second end member.
A high temperature heat exchanger for the convection of heat between a primary circulating fluid and a secondary circulatory fluid, comprising:
- an exchanger body comprising a plurality of heat exchange blocks sealingly stacked along a longitudinal axis, each side block having opposite, parallel planar surfaces adapted for stacking, said exchanger body having a respective proximate and distal parallel surface at opposite ends of said axis;
- a first end member having a planar surface in sealing contact with said proximate planar surface of said exchanger body and having at least two inclined surfaces opposite said planar surface;
- a second end member having a planar surface in sealing contact with said remote planar surface of said exchanger body and having at least two inclined surfaces opposite said planar surface;
- means on said first end member separating said inclined surfaces for forming a primary first end chamber and a secondary first end chamber, said first end chambers for respectively receiving a primary fluid and a secondary fluid;
- means on said second end member separating said inclined surfaces for forming a primary second end chamber and a secondary second end chamber, said second end chambers for respectively receiving the primary fluid and the secondary;
- means extending from said first end member through said exchanger body to said second end member for conducting primary fluid between said primary first end chamber and said primary second end chamber and for conducting said secondary fluid between said secondary first end chamber and said secondary second end chamber.
