Claims

[Scope of utility model registration request]

(1) In a refrigerator that forcibly circulates cold air by sending cold air cooled by a sub-cooler into a freezing chamber through a cold air outlet, a refrigerant passage portion in the form of a circuit network formed in a horizontal plate-shaped portion; Secondary cooling consisting of a horizontal tube section formed by communicating with the refrigerant passage so that the internal refrigerant circulates through the rising tube section, and a plurality of radiation fins provided on this horizontal tube section. 1. A refrigerator characterized in that a quick freezing chamber is provided by providing a cooling device, and radiating fins of a horizontal pipe body portion of the secondary cooling/cooling device are provided adjacently to a cold air outlet in the freezing chamber.

(2) The refrigerator according to claim 1, wherein the secondary cooler is a thermosiphon type heat pipe that moves the refrigerant condensed and liquefied in the horizontal pipe section to the refrigerant passage section by gravity.

(3) The refrigerator according to claim 1, wherein the secondary cooler is a capillary heat pipe that moves the refrigerant condensed and liquefied in the horizontal pipe body to the refrigerant passage by the capillary force of the wick. .

(4) The refrigerator according to claim 1, 2, or 3, wherein the horizontal plate portion of the secondary cooler is removably locked in the freezer compartment.
