Method and device for minimizing adverse effects of temperature differential in a heat exchanger or heat exchange reactor
View Patent ↗A heat exchange apparatus includes first and second sections, and further includes a first cross-flow fluid passageway disposed at least partially within the first section, defined by an internal surface of the first section, and including an inlet and outlet. The apparatus also includes a second cross-flow fluid passageway disposed at least partially within the second section and including an inlet and an outlet. The apparatus includes an interior fluid passageway with at least one tube disposed at least partially within the first section and at least partially within the second section, extending at least partially through the first passageway and at least partially through the second passageway, and including at least an inlet and an outlet. A sealing zone is disposed between the first section and the second section. The sealing zone isolates the first section from the second section either or both mechanically and in fluid communication.
1. A heat exchange apparatus comprising: a first housing section; a second housing section; a first cross-flow fluid passageway disposed at least partially within the first housing section and defined by an internal surface of the first housing section and including a first inlet and a first outlet; a second cross-flow fluid passageway disposed at least partially within the second housing section and including a second inlet and a second outlet; an interior fluid passageway defined by at least one tube disposed at least partially within the first housing section and at least partially within the second housing section, extending at least partially through the first passageway and at least partially through the second passageway, and including at least a third inlet and a third outlet; and means for reducing transmission of shear stress from the first housing section to the second housing section, the means for reducing transmission of shear stress being disposed between the first housing section and the second housing section, wherein the at least one tube passes through the means for reducing transmission of shear stress, wherein the means for reducing transmission of shear stress includes a vent fluidly connecting an area internal to the means for reducing transmission of shear stress with an area external to the means for reducing transmission of shear stress.
2. The heat exchange apparatus according to claim 1 , wherein the vent includes a gap disposed between the first housing section and second housing section.
3. The heat exchange apparatus according to claim 1 , wherein the first housing section does not contact the second housing section.
