PROBLEM TO BE SOLVED: To provide a refrigerator capable of surely brazing a dew-proofing pipe to the other connected-pipe functioned as a condenser while preventing a refrigerant flow from slowing by reducing a diameter of the dew-proofing pipe. SOLUTION: The dew-proofing pipe can be brazed to a radiation pipe without melted, though a heat capacity per unit length of the conventional dew-proofing pipe is roughly half of a heat capacity per unit length of the radiation pipe as the connected pipe. Accordingly, the dew-proofing pipe can be brazed to the radiation pipe without melted by setting the heat capacity per unit length of the dew-proofing pipe to be more than roughly half of the heat capacity per unit length of the radiation pipe while reducing an inner diameter of the dew-proofing pipe to increase a flow speed of a refrigerant. Here, the heat capacity per unit length of the dew-proofing pipe is adjusted on the basis of a thickness of the pipe. COPYRIGHT: (C)2009,JPO&INPIT
