    Abstract: The present disclosure is related to nested cooling and heating systems. The cooling system includes an outer cooling assembly with an inner cooling assembly inserted within the outer cooling system. The inner cooling assembly includes thermoelectric coolers, and the outer cooling assembly may thermoelectric or vapor compression driven. Additional intermediate cooling assemblies may be nested together with the inner and outer cooling assemblies to increase the cooling effect in the innermost cooling assembly. Similarly, the heating system uses nested thermoelectric heating assemblies, and hot temperatures can be increased by adding intermediate nested heating assemblies. Intermediate and/or inner assemblies may be removed from the outer assembly to allow for easy transport

    Abstract: 内部熱交換器（１８）は、外管（１８１）と内管（１８２）とを有する。内部熱交換器（１８）は、反膨張弁側コネクタ（３１）において流体的な連通関係を提供するように接続されている。内部熱交換器（１８）は、膨張弁側コネクタ（１８６）において流体的な連通関係を提供するように接続されている。外管（１８１）と内管（１８２）とは、同芯構造を介して互いに圧着されている。圧着は、外管（１８１）と内管（１８２）との相対的なずれの抑制に貢献する。反膨張弁側コネクタ（３１）と膨張弁側コネクタ（１８６）との少なくとも一方は、内管（１８２）の移動を許容する。製造方法は、外管（１８１）の先端と内管（１８２）の先端との同軸度を回復させる工程を含む。

    Abstract: In a heat exchanger with double-walled tubes (11), an end junction (10) between inner tube (12) and outer tube (13) comprises an end plate (15) in which there is a seat (16) in which an end portion of the inner tube (12) is housed. The corresponding outer tube (13) is peripherally fixed sealingly around the opening (17) of the seat and a deflector (25) extends the inner wall of the outer tube (13) inside the seat (16) so as to define a toroidal cavity (26) between the deflector (25) and a side wall (18) of the seat (16). The seat (16) is closed by a bottom (19) which is opposite to the opening (17) of the seat and which has a passage (20) connected sealingly to the end of the inner tube (12) in the seat for the transit of the fluid to be cooled. A radial space (27) is present near the said bottom (19) between the toroidal cavity (26) and internal cavity (14) of the double-walled tube, and the end plate (15) has at least one conduit (22) which emerges inside the toroidal cavity (26) for the inflow or outflow of the cooling fluid. In this way a junction (11) and an exchanger (40) with such a junction which are robust and have innovative performance features may be provided.
