ABSTRACT:
In a method of manufacturing a condenser for a refrigerator, a heat discharging tube is attached to a heat discharging plate made of ABS resin to improve a heat discharging effect of the condenser, while a back portion of the refrigerator is covered with the heat discharging plate to improve an external appearance. A heat discharging tube is disposed on a lower molding jig, and the heat discharging tube is covered with a heat discharging plate. An upper molding jig and a lower molding jig are combined with each other, and air is discharged between the lower molding jig and the heat discharging plate to create vacuum therebetween so that the heat discharging plate is combined to the heat discharging tube by a vacuum-sucking force. The heat discharging plate is refrigerated in a state of combining the heat discharging plate to the heat discharging tube after separating said upper molding jig and said lower molding jig from each other, and then the heat discharging plate integrally combined to the heat discharging tube is separated from the lower molding jig.
