A recess in the longitudinal tube shell holds the end plate, resolving sealing reliability issues caused by complex inner contours.
A heat exchanger plate dimple with a sloped area distributes stress to withstand high test pressures.
Differentiated porthole flat areas prevent plate collapse by maintaining consistent port diameters and flow communication in three-media heat exchangers.
Perpendicular wall covers the sealed junction zone to isolate it from external particles, preventing corrosion while maintaining tightness.
Contiguous bearing areas prevent release under high pressure without reducing inner volume.
A flat heat exchanger tube uses a triple wall nose structure to absorb impact energy and prevent deformation.
A structured support mask integrates between outer plates and frame end plates to distribute clamping force evenly across corrugated surfaces.
Reinforcer with projections prevents backplate deformation and cracking around heat exchange channels.
Inclined beams relocate contact zones away from thinnest ends, preventing material cracks and uneven load distribution.
