Abstract
A heat transfer device comprising a liquid having a low boiling point and a non-condensable gas, said liquid and said gas being charged in a vessel, said vessel being separated into a heating section and a cooling section by means of an adiabatic member to cause said liquid to boil at temperatures above a desired temperature. In the heat transfer device, a great amount of heat is transferred at temperatures above a desired temperature by causing vapor bubbles to transfer from said heating section to said cooling section, said bubbles resulting from boiling of said liquid, while no heat transfer is effected between the aforesaid two sections at temperatures below the desired temperatures. The heat transfer device is suited for use in such apparatuses or machines which require a thermal valving function, especially for use in a refrigerator.
