US 2026/0276151 A1 · CRYOGENIC SUB-COOLING

Abstract

The invention provides a method for subcooling a cryogenic liquid (1), the method comprising providing a discharge element (2) comprising a first discharge element portion (23) comprising (i) a discharge element inlet opening (21), (ii) a throttle element (25), and (iii) a heat conductive wall (28); providing a cryogenic liquid (1) in an open container (10); immersing the first discharge element portion (23) in the cryogenic liquid (1) in the open container (10); and reducing a pressure in the discharge element (20) at a downstream side (26) of the throttle element (25), thereby inducing a flow of the cryogenic liquid (1) from an upstream side (24) of the throttle element (25) through the throttle element (25), wherein at least part of the cryogenic liquid (1) changes phase at the downstream side (26) of the throttle element (25), thereby providing a heat flow from the cryogenic liquid (1) surrounding the discharge element (20) to the first discharge element portion (23).

Dependent claims

A method for subcooling a cryogenic liquid (1), wherein the method comprises:

providing a discharge element (2) comprising a first discharge element portion (23) comprising (i) a discharge element inlet opening (21), (ii) a throttle element (25), and (iii) a heat conductive wall (28),
providing a cryogenic liquid (1) in an open container (10),
immersing the first discharge element portion (23) in the cryogenic liquid (1) in the open container (10), and
reducing a pressure in the discharge element (20) at a downstream side (26) of the throttle element (25), thereby inducing a flow of the cryogenic liquid (1) from an upstream side (24) of the throttle element (25) through the throttle element (25), wherein at least part of the cryogenic liquid (1) changes phase at the downstream side (26) of the throttle element (25), thereby providing a heat flow from the cryogenic liquid (1) surrounding the discharge element (20) to the first discharge element portion (23).

1 more element

A system (100) for subcooling a cryogenic liquid (1), wherein the system (100) comprises (i) a discharge element (20) comprising a first discharge element portion (23), (ii) a further discharge element portion (29) fluidically connected to the first discharge element portion (23), and (iii) a pumping device (30), wherein the first discharge element portion (23) comprises a discharge element inlet opening (21), a throttle element (25) and a heat conductive wall (28);

wherein
the pumping device (30) is fluidically coupled to the further discharge element portion (29) and configured for reducing a pressure in the discharge element (20) at a downstream side (26) of the throttle element (25), for providing the cryogenic liquid (1) to flow from an upstream location (24) of the throttle element (25) through the throttle element (25), wherein at least part of the cryogenic liquid (1) changes phase at the downstream side (26) of the throttle element (25), if the discharge element inlet opening (21) and the first discharge element portion (23) are configured in the cryogenic liquid (1) and the further discharge element portion (29) protrudes from the cryogenic liquid (1).
