Refrigerator with vacuum insulation housing a liquid-gas interchanger

摘要

A refrigerator includes an inner case, an outer case, a vacuum space, and a liquid-gas interchanger. The inner case defines an exterior appearance of a storage space. The outer case is spaced apart a predetermined distance from the inner case. The vacuum space is provided between the inner case and the outer case, and maintains a vacuum to insulate the inner case from the outer case. The liquid-gas interchanger is arranged in the vacuum space to generate heat exchange between a refrigerant after it is exhausted from an evaporator and a refrigerant before it is drawn into an evaporator.

1. A refrigerator comprising:
a case in which a freezer compartment and a refrigerator compartment are formed, the case including an inner case, an outer case accommodating the inner case and vacuum space provided between the inner case and the outer case; a plurality of spacers arranged to maintain the vacuum space between the inner case and the outer case; a first door configured to open and close the freezer compartment; a second door configured to open and close the refrigerator compartment; and a heat exchanger configured to generate heat exchange between refrigerant that has passed an evaporator and refrigerant that is being drawn into the evaporator, wherein the heat exchanger is provided within the vacuum space, wherein only a first end and a second end of the heat exchanger are welded to the inner case and the outer case, respectively, with a fixing force and airtightness that endures a vacuum pressure of the vacuum space, and wherein portions other than the welded first end and the welded second end of the heat exchanger are spaced apart from the inner case and the outer case.
