た。However, according to the conventional structure, the temperature in front of the plate 12 becomes high,
The temperature of the rear part also becomes high due to the heat radiation of the compressor 10. For this reason, the defrost water evaporator 11 does not have much air convection effect, and on the contrary, the backside temperature of the compressor 10 rises, and if the refrigerator 1 is installed with its back and side walls closely fitted, the compressor will be compressed. The backside temperature of 10 further rises, and the compressor 10
There was a case where the internal parts of the machine were worn out, resulting in lack of reliability.

温度が下がる。In the above structure, the high temperature refrigerant discharged from the compressor 10 is heated by the heating pipe 13 'as shown in FIG.
At this time, since the plate 12 'is arranged from the rear side to the front side, the rear portion of the plate 12' has a large amount of heat conduction, and the heat dissipation of the heating pipe 13 'progresses toward the front side, and The temperature of 12 'also decreases. Therefore, air convection is generated from the front side to the rear side of the heat dissipation device 11 ', increasing the convection flow rate and simultaneously lowering the back surface temperature of the compressor 10.

より効果的に蒸発される。At the same time, since the plate 12 'is inclined upward toward the rear, the suction opening 8'of the suction grille 8 is formed.
The air sucked in further flows obliquely from the front of the plate 12 ′ and flows backward, and since the conventional evaporation pan 14 ′ is not on the heat dissipation device 11, the resistance of air convection is reduced, and the exhaust of the machine room 7 is exhausted. Since it is accelerated through the discharge port 9'of the discharge grill 9, the air on the heat dissipation device 11 'is attracted to increase the counter flow rate, and the heat dissipation effect is also promoted from this aspect. It should be noted that the defrosting water accumulated in the evaporating dish 14 'is radiated by the compressor 10 and at the same time convection is promoted by the heat radiating port 14'a provided inside the evaporating dish 14', so that the air flowing from the front of the plate 12 'is removed. Since it enters the inside of the evaporation dish 14 'and flows into the discharge port 9', it is more effectively evaporated.

る。As described above, the heat dissipation device of the present invention comprises the compressor, the plate for promoting heat dissipation, and the heating pipe through which the high temperature refrigerant flows, and the heating pipe is directed from the rear side to the front side of the plate. Are arranged in a meandering manner and the plate is inclined forward. This allows
Since the ambient temperature of the heat dissipation device is low in the front and high in the rear, a temperature difference occurs, and air convection occurs from the front to the rear.

ート前方より傾斜に沿って流れ、さらに放熱装置の上に
蒸発皿がないため空気対流の抵抗が減少し、対流量が増
加し、この面からも放熱作用が促進される。Further, since the plate is inclined upward toward the rear, the air sucked into the plate flows along the inclination from the front of the plate, and since there is no evaporation tray above the radiator, air convection is caused. The resistance is reduced, the flow rate is increased, and heat dissipation is promoted also from this aspect.

なり、その効用は極めて大きいものである。When the convection of air is increased, the temperature of the back surface of the compressor is lowered, wear of internal parts of the compressor is less likely to be promoted, and the reliability of the compressor is enhanced. Furthermore, when the backside temperature of the compressor decreases, the temperature of the refrigerant circulating in the refrigerator also decreases, so the refrigerating capacity increases, and the temperature inside the refrigerator decreases, which reduces the operating rate of the compressor and reduces power consumption. And its utility is extremely large.
