Abstract: PURPOSE: To achieve an accurate prevention of frosting on the front rim part of an outer case and further, a lowering of power consumption by a method wherein a heat radiation pipe is mounted on the rear of a double flange of an outer case and a highly heat conductive hot melt is applied on the perimeter of the heat radiation pipe by a nozzle of a robot or the like to raise a heat radiation efficiency of the heat radiation pipe. CONSTITUTION: A heat radiation pipe 2 is mounted on the rear of a double flange of an outer case 11 by a fixing metal fitting 13 and a hot melt 14 is applied thereon by a nozzle 15 of a robot being bent from a front opening part of an outer case 2. The tip 15a of the nozzle 15 is worked roughly in a U shape so that the hot melt 14 penetrates on both sides of the heat radiation pipe 12. The heat radiation pipe 12 directly contacts the outer case 11 and positively transmits heat to the outer case 11 by the hot melt 14 and the radiation of heat to the outside air is increased. To the contrary, the quantity of heat transferring from a turned-back flange 11b and an internal flange 11d into the storage decreases.

Abstract: PURPOSE: To prevent infiltration of defrosted water into a heat insulting foam material while hindering the movement of a suction link part during the filling of the heat insulating foam material being foamed by a method wherein a pipe guide hole to a freezing compartment at a pipe link part of a suction pipe is provided at an inner upper part of an inner case and an engaging part is provided at the rear part of a mid partition wall heat insulating material to fix the suction pipe. CONSTITUTION: A retaining part 16a is formed at the rear part of a mid partition wall heat insulating material 16 so that a suction pipe 19 and a heat reserving tube 21 housing a capillary tube 20 inside are fitted thereinto and the heat reserving tube 21 is fixed by a tape 23. A suction link part 19a and a capillary link part 20a are led out of a pipe guide hole 17a provided on an inner top surface of a freezing compartment 5 in an inner case 17. The retaining part 16a of the mid partition wall heat insulating material 16 eliminates the horizontal movement of the suction pipe 19 thereby getting rid of the positional deviation of the suction link part 19a and the capillary link part 20a. This enables the preventing of the deformation and breaking of the pipe as caused by a foaming jig and the pipe guide hole 17a of the inner case 17 located at the inner upper part of the freezing compartment keeps defrosted water from infiltrating into the heat insulating foam material from the suction link part 19a.

Abstract: PURPOSE: To prevent infiltration of defrosted water into a heat insulating foamed material while preventing bending or the like of a pipe caused by a foaming jig by arranging a pipe guide port to a freezing compartment at a pipe link part of a suction pipe at an inner upper part of an inner case to form a bent part positionally shifted on the vertical line from the pipe guide hole in the suction pipe. CONSTITUTION: A suction link part 19a and a capillary link part 20a are led out of a pipe guide hole 17a provided on an inner top surface of a freezing compartment 5 of an inner case 17 and a suction pipe 19 has a bent part 19b formed in the direction opposite to the pipe guide hole 17a of the inner case 17. When the bent part 19b of the suction pipe 19 is mounted on the body of a refrigerator, forcible vertical movement thereof allows absorbing of an allowance and variations in the length dimension of the suction pipe 19 to prevent the deformation or the bending of the pipe as caused by a foaming jig. Since the pipe guide hole 17a of the inner case 17 is located at an inner upper part of the freezing compartment, defrosted water of frost on the pipe will not infiltrate into the heating insulating foam material from the suction link part 19a.
