Abstract

A cold appliance, such as a household refrigerator or freezer, comprising a cooling module ( 102 ) and a cabinet ( 101 ). The cabinet has been assembled from pre-foamed panels comprising two opposite side wall panels ( 1 ), a rear wall panel ( 4 ), a top part ( 2 ), and a bottom part ( 103 ), which are connected essentially perpendicular to each other e.g. by means of mechanical and/or or glue joints, and a door ( 6 ). The cabinet comprises a condensation preventing device ( 160 ) comprising a heat carrier tube ( 28, 160 ) being positioned at a front frame portion of the cabinet of the cold appliance, preferably adjacent to a part of the door ( 6 ). The heat carrier tube being filled with a heat carrier fluid, being closed and having a boiler portion ( 172 ), which is arranged in thermal contact with a heat generating means ( 32 ) of said cooling module for boiling the heat carrier fluid.
