Refrigerator

摘要

A refrigerator as disclosed herein may include a refrigerator body having a freezing compartment and a refrigeration compartment, a cooling circuit including a compressor, a condenser, and an evaporator to cool the freezing compartment and the refrigeration compartment using a first refrigerant, and a thermosyphon that includes a pipe for a second refrigerant to flow. The pipe may have a first section having a first prescribed shape for condensing refrigerant and a second section having a second prescribed shape for vaporizing refrigerant. A valve may be provided at the pipe to operate the thermosyphon. The cooling circuit and the thermosyphon may be operated independently. The thermosyphon may provide auxiliary cooling for the refrigeration chamber when the cooling circuit is not operational.

1. A refrigerator comprising:
a refrigerator body having a freezing compartment and a refrigeration compartment; a cooling circuit including a compressor, a condenser, and an evaporator to cool the freezing compartment and the refrigeration compartment using a first refrigerant; a thermosyphon that includes a pipe for a second refrigerant to flow, the pipe having a first section having a first prescribed shape, a second section having a second prescribed shape, a third section coupled between the first and second sections for the second refrigerant to flow from the first section to the second section, and a fourth section coupled between the first and second sections for the second refrigerant to flow from the second section to the first section; and a valve provided at the pipe to open or close the pipe, wherein the freezing compartment is positioned adjacent to the refrigeration compartment, and the first section of the pipe is positioned at the freezing compartment to undergo heat exchange with the freezing compartment and the second section of the pipe is positioned at the refrigeration compartment to undergo heat exchange with the refrigeration compartment, the first section being positioned higher than the second section, wherein the second refrigerant changes state from a gaseous state to a liquid state in the first section of the pipe and changes state from a liquid state to a gaseous state in the second section of the pipe, wherein the cooling circuit and the thermosyphon are operated independently, wherein the pipe includes a fifth section having a third prescribed shape that prevents the second liquid refrigerant in the first section from moving into the fourth section through the fifth section, wherein the fifth section is positioned at an entrance of the first section and extends above the first section such that all refrigerant moving from the fourth section to the first section ascends above the top of the first section while passing through the fifth section and descends at the entrance of the first section, and wherein the second refrigerant goes down in the gaseous state and goes up in the liquid state in the thermosyphon.
