Title:
REFRIGERATOR
Document Type and Number:
Japanese Patent JP2020094756
Kind Code:
A
Abstract:
To hold predetermined cooling capacity even when a cycle of a defrosting operation is extended, and to suppress power consumed by the defrosting operation.SOLUTION: A refrigerator includes a heat exchanger for cooling the cool air in an internal space. The heat exchanger includes: a plurality of fins arranged separated from one another; a refrigeration pipe provided so as to penetrate the plurality of fins; a pair of first end surface parts formed by outer edges of the plurality of fins and opposing to each other; and a pair of second end surface parts formed so as to cross both first end surface parts by the outer edges of the plurality of fins, and opposing to each other. The heat exchanger has a plurality of heat exchange regions which are arranged so that cool air passes from one first end surface part side to the other first end surface part, and which are arranged side by side along the opposing direction of both second end surface parts. Each heat exchange region includes the refrigeration pipe separately, and a refrigerant flowing in the refrigerant pipe of at least one heat exchange region out of the plurality of heat exchange regions becomes lower in temperature than the refrigerant flowing in the refrigerant pipe of other heat exchange regions.SELECTED DRAWING: Figure 3
