US 12,480,714 B2 · Heat exchanging channel forming an internal cavity that stores cryogenic material

Abstract

A heat exchanger comprises an inlet, an outlet, a heat exchanging channel, and an opening. The heat exchanging channel surrounds a cavity. The opening provides access to the cavity. The inlet is coupled to one end of the heat exchanging channel and the outlet is coupled to another end of the heat exchanging channel. The heat exchanging channel is isolated from the cavity. No access or passage is present between the heat exchanging channel and the cavity. During operation, heat exchanging fluid flows through the heat exchanging channel thereby cooling fluid within the cavity. The heat exchanging fluid never contacts the fluid within the cavity. In various embodiments, the heat exchanging channel has a single or stacked layer when viewed along a cross section. The heat exchanging channel has a spherical, cylindrical, or rectangular shape. In one embodiment, an insulative layer is disposed between layers of the heat exchanging channel.

Dependent claims

An apparatus comprising:

a cavity for holding a stored fluid;
an opening that provides access to the cavity;
an inlet to a heat exchanging channel and an outlet from the heat exchanging channel;
the heat exchanging channel surrounding the cavity, the heat exchanging channel comprising a first layer bounding the cavity and a second layer outside the first layer, the first layer in fluid communication with the second layer to allow a flow of heat transfer fluid from the inlet to the outlet such that the heat transfer fluid Said controls a temperature of the stored fluid in the cavity;
and
the cavity comprising a stored fluid exit connected to a passage extending between the first layer and the second layer, the passage allowing a flow of the stored fluid from the stored fluid exit of the cavity to a stored fluid outlet controlling flow of the stored fluid to an exterior away from the cavity.
