Problems solved by technology

However, due to the configuration of the flow path, etc., there is a problem that the volume of the library decreases due to the increase in the useless space.
In addition, the shield plate in contact with the cooler 7 is thermally deformed by the radiant heat from the defrosting heater during defrosting, and the material has a different coefficient of linear expansion, which may cause abnormal noise between the cooler 7 and the shield plate. question

Abstract

The refrigerator includes: a freezer compartment partitioned by an insulating wall; a refrigerator compartment arranged above the freezer compartment; and a cooling compartment provided behind the freezer compartment. In addition, there are: a cooler (107) in which refrigerant tubes (145) having fins (146) are stacked in the vertical direction arranged in the cooling chamber; Refrigerator return duct that returns cold return air from the refrigerator to the cooler. In addition, the lower part of the width dimension of the refrigerant pipe (145) of the cooler (107) is shorter than the upper part of the width dimension of the refrigerant pipe (145), thereby improving the cooling efficiency by reducing the pressure loss of the air passage, In addition, it is possible to disperse the part of the cooler (107) to which frost adheres.

Description

technical field [0001] The present invention relates to a refrigerator cooled by circulating cool air generated by a cooler with a fan. Background technique [0002] In recent years, the energy saving of refrigerators has been continuously advanced. In order to reduce the power consumption of refrigerators, it is not only necessary to improve the efficiency of cooling efficiency, but also to suppress cooling even when frost is attached to the cooler during actual use such as door opening and closing. The drop in efficiency is significant. [0003] Among them, in order to reduce the power consumption of the refrigerator, as a method of suppressing the reduction of cooling efficiency caused by the frost attached to the cooler, in the existing refrigerator, the following structure is proposed: For example, in a refrigerator with high humidity When cold air is returned to the cooler in the refrigerator, the cold air passes through the guide plate arranged at the lower part of t...
