Refrigeration device

Abstract

A refrigeration device includes: a refrigerator; a heat pipe that includes a condensation unit connected to the refrigerator in a manner that heat exchange is enabled and adapted to condense a refrigerant, includes an evaporation unit connected to a storage chamber housing an object that should be stored in a manner that heat exchange is enabled and adapted to evaporate the refrigerant, and includes a piping circulating the refrigerant between the condensation unit and the evaporation unit; a refrigerant chamber connected to the heat pipe and adapted to pool the refrigerant; and a heater that heats the refrigerant chamber.

What is claimed is: 
     
         1 . A refrigeration device comprising:
 a refrigerator;   a heat pipe that includes a condensation unit connected to the refrigerator in a manner that heat exchange is enabled and adapted to condense a refrigerant, includes an evaporation unit connected to a storage chamber housing an object that should be stored in a manner that heat exchange is enabled and adapted to evaporate the refrigerant, and includes a piping circulating the refrigerant between the condensation unit and the evaporation unit;   a refrigerant chamber connected to the heat pipe and adapted to pool the refrigerant; and   a heater that heats the refrigerant chamber to a temperature higher than that of the evaporation unit.   
     
     
         2 . The refrigeration device according to  claim 1 , wherein
 the heater heats the refrigerant chamber so that a temperature difference between the evaporation unit and the refrigerant chamber is 100° C. or more.   
     
     
         3 . The refrigeration device according to  claim 1 , wherein
 a volume of the refrigerant chamber is not less than 1.5 times a volume of the heat pipe.
