The refrigerator of claim 1, further comprising a heat transfer compound applied at an interface between the bent sections and the heat-exchanging plate. 10. The refrigerator of claim 1, wherein the bent sections are assembled with the heat-exchanging plate by vacuum brazing. 11. The refrigerator of claim 1, wherein the bent sections are moulded within the heat-exchanging plate. 12. The refrigerator of claim 1, wherein the fluid connection loop comprises one or more through channels of the heat-exchanging plate connected to a plurality of tubes. 13. The refrigerator of claim 1, wherein the fluid connection loop is assembled with the heat-exchanging plate by a molten zinc dip. 14. The refrigerator of claim 1, wherein the heat exchanger comprises a plurality of fin-shaped projections extending outward from the second surface of the heat exchanging plate to define sides of the receiving channels. 15. The refrigerator of claim 14, wherein the fin-shaped projections defining sides of the receiving channels are aligned on either side of the bent sections of the serpentine portion of the fluid connection loop. 16. The refrigerator of claim 15, wherein the heat exchanger comprises a plurality of fin-shaped projections extending outward from the first surface of the heat exchanging plate. 17. The refrigerator of claim 16, wherein the plurality of fin-shaped projections extending outward from the first surface of the heat exchanging plate comprises a set of short, fin-shaped projections and a set of long, fin-shaped projections, a short, fin-shaped projection being arranged adjacent to a long, fin-shaped projection. 18. The refrigerator of claim 1, wherein the first surface of the heat exchanging plate is exposed to the interior of the sub-compartment to provide force convection cooling to the sub-compartment.
