  • Patent number: 5157941
    Abstract: A tube and fin-type evaporator is provided for a refrigerator having trapezoidally shaped fins with the wider portion of the fins disposed upstream in the cooling air flow path through the evaporator. The refrigerant tube passes through at least two rows of openings in these fins, and those openings are staggered and of different length to enhance turbulence and reduce tube shielding within the cooling air flow. Projections (dimples) on the fins adjacent the downstream side of each opening are provided to reduce dead air space downstream from the tube. Further, the openings are provided with collars to increase heat transfer between the fins and the tube. These projections and collars also serve to increase rigidity of the fins. The present invention enables the use of relatively small diameter, thin walled refrigerant tubes within the evaporator. Also, the tubes can be hydraulically expanded within the fins to enhance fin to tube contact and decrease heat transfer resistance.

  • Patent number: 5081850
    Abstract: The refrigerator of this invention includes a thermal insulating box, an upper storing box and a lower storing box within the thermal insulating box, and a cooling unit arranged above the upper storing box. An interior space within the thermal insulating box is divided into a first passage communicating with a cold air blowing side of the cooling unit to cool the storing box while lowering the cold air and a second passage communicating with a cold air sucking side of the cooling unit to cool the storing box while raising the cold air descended down to the bottom part of the thermal insulating box and to return the cold air to the cooling unit. A space having the cooling unit stored therein is divided by a partition wall into a first chamber having the cooling unit arranged therein and a second chamber having an air blowing fan arranged therein. The partition wall is provided with through-holes at locations corresponding to the cold air passage within the first chamber.
