Abstract:
1. A cooling system for a vacuum processing apparatus, in which a subject body is treated with a vacuum treatment, the cooling system comprising: an internal heat conduction path comprising a heat pipe, the internal heat conduction path transferring heat entering the subject body through the vacuum processing apparatus; a heat release path configured to release the transferred heat to an exterior of the vacuum processing apparatus; and a heat conduction path configured to regulate quantity of heat transfer between the internal heat conduction path and the heat release path, the heat conduction path comprising a wall member and a fluid regulation unit, the wall member isolating the internal heat conduction path and the heat release path so as to form a space, the fluid regulation unit controllably filling a fluid for heat conduction into the space, wherein the heat release path comprises a solid heat transfer member with no internal fluid flow path penetrating a vacuum partition wall composing the vacuum processing apparatus, wherein a first end of the heat transfer member contacts the wall member and a second end of the heat transfer member is disposed outside of the vacuum processing apparatus and thermally connects with a cooling medium, wherein the heat pipe is elongated to have a first end thermally connected with the heat conduction path so as to conduct the transferred heat to the heat conduction path.
