Rolled heat exchange
View Patent ↗The invention relates to a rolled heat exchanger with several pipes that are wound around a central pipe, with a casing that delimits an external space around the pipes and with a liquid distributor for distributing liquid in the external space. According to the invention, the liquid distributor is designed as a pipe manifold that has a main channel ( 21 ) and several distributing arms ( 22 ) that are flow-connected to the main channel ( 21 ).
1. Heat exchanger with several pipes that are wound around a central pipe, with a casing that delimits an external space around the pipes and with a liquid distributor for distributing liquid in the external space, characterized in that the liquid distributor is designed as a pipe manifold that has a main channel ( 21 ) and several distributing arms ( 22 ) that are flow-connected to the main channel ( 21 ) and have liquid outlets ( 23 ) positioned on their underside, wherein the distributing arms ( 22 ), starting from the main channel ( 21 ), run radially outward and
the height of the distributing arms ( 22 ) decreases in radial direction.
2. Heat exchanger with several pipes that are wound around a central pipe, with a casing that delimits an external space around the pipes and with a liquid distributor for distributing liquid in the external space, characterized in that the liquid distributor is designed as a pipe manifold that has a main channel ( 21 ) and several distributing arms ( 22 ) that are flow-connected to the main channel ( 21 ) and have liquid outlets ( 23 ) positioned on their underside
wherein a device ( 28 ) for reducing the kinetic energy of the incoming liquid is provided in the main channel ( 21 ).
3. Heat exchanger with several pipes that are wound around a central pipe, with a casing that delimits an external space around the pipes and with a liquid distributor for distributing liquid in the external space, characterized in that the liquid distributor is designed as a pipe manifold that has a main channel ( 21 ) and several distributing arms ( 22 ) that are flow-connected to the main channel ( 21 ) and have liquid outlets ( 23 ) positioned on their underside
wherein a perforated plate, a static mixer or an ordered packing ( 28 ) is provided to reduce the kinetic energy of the incoming liquid.
4. Rolled heat exchanger with several pipes that are wound around a central pipe, with a casing that delimits an external space around the pipes and with a liquid distributor for distributing liquid in the external space, whereby the liquid distributor is designed as a pipe manifold that has a main channel ( 21 ) and several distributing arms ( 22 ) that are flow-connected to the main channel ( 21 ), characterized by at least one of the two following additional features:
a perforated plate, a static mixer or an ordered packing ( 28 ) arranged in the main channel ( 21 ), to reduce the kinetic energy of the incoming liquid, or
the distributing arms ( 22 ) form a cavity in the shape of pie slices.
5. Heat exchanger according to claim 4 , characterized in that in the main channel ( 21 ), both a perforated plate, a static mixer or an ordered packing ( 28 ) for reducing the kinetic energy of the incoming liquid is provided and the distributing arms ( 22 ) form a cavity in the shape of pie slices.
6. Heat exchanger according to claim 4 , wherein the main channel ( 21 ) runs inside a portion of the central pipe ( 24 ).
7. Heat exchanger according to claim 6 , wherein the inside diameter of the main channel ( 21 ) is smaller than the inside diameter of the central pipe ( 24 ).
8. Heat exchanger according to claim 4 , wherein the distributing arms ( 22 ), starting from the main channel ( 21 ), run radially outward.
9. Heat exchanger according to claim 8 , wherein the height of the distributing arms ( 22 ) decreases in radial direction.
10. Heat exchanger according to claim 4 , wherein the distributing arms ( 22 ) have liquid outlets ( 23 ), whereby the density of the liquid outlets ( 23 ) changes in radial direction.
