Title:
HEAT SWITCH
Document Type and Number:
WIPO Patent Application WO/2001/081851
Kind Code:
A1
Abstract:
A heat switch which is relatively simple in construction, quick in switching action, and satisfactory in heat cut-off ability. The wicks in the heating and cooling sections, respectively, of a heat pipe are separated from each other, and a flow channel is provided which returns a heat medium from the cooling section to a heat medium reservoir. Feeding of the heat medium to the heating section is from the heat medium reservoir through the heating section wick. The heat medium reservoir is of volume-variable construction. Changing the volume of the heat medium reservoir controls contact and noncontact between the heating section wick and the heat medium, thereby providing on-off control of the heat transmission of the heat medium.
