Integrated refrigerant storage canister and heat exchanger

DETAILED DESCRIPTION What is claimed is: 1.
An integrated refrigerant storage canister and heat exchanger, especially a device which in use occupies a generally upright position including a.
an assembly comprising nested inner and outer containers, the former being adapted to contain a solid state refrigerant sublimated by a transfer of heat through defining wall portions of said inner container into the refrigerant, b.
said inner container having a closed bottom wall portion in supporting relation to a contained refrigerant material, c.
means for conducting released gas from said inner container, d.
means for conducting a circulating fluid absorbing heat at a relatively remote source to and from said assembly, e.
and means for conducting the circulating fluid through said assembly by way of a path requiring it to pass between said containers in heat transfer relation to said bottom wall portion of said inner container, f.
side and bottom wall portions of said inner and outer containers being in a spaced relation to one another, g.
separators positioning longitudinally within the space between side wall portions and defining vertical flow passes interconnected at their lower ends by a space between bottom wall portions defining a horizontal flow pass, h.
there being connections to and from upper ends of respective vertical flow passes for inflow and outflow of said fluid, i.
and said connections and said separators cooperating to require a path of flow for said fluid taking it downward in one of said vertical flow passes, transversely through said horizontal flow pass and upwardly in the other of said vertical flow passes.
2.
A device according to claim 1, wherein a.
means positions to close upper ends of said containers, b.
and segmental orifice plate segments position in said vertical flow passes to form above them manifold inlet and outlet chambers, c.
said segments positioned to opposite sides of said separators.
3.
A device according to claim 2 wherein a.
said vertical flow spaces are each occupied by a secondary surface heat transfer material, said material being in each instance flexible fin means extending at upper and lower ends between a respective orifice plate segment and a lower end of a respective vertical flow pass, b
