Applicator mechanism is for applying liquid or paste medium on one side or both sides of running paper or board and cools ambient air on applicator surface using heat pipe principle

摘要

An applicator (10) surface exposed to the ambient air, and/or at least a surface exposed to the ambient temperature and located in the vicinity of the applicator, can be cooled by means of a cooling unit with a heat pipe/pipes (18,18',18) to a cooling temperature, which effects or facilitates condensation of moisture from the ambient air on the surface. The heat pipe features a heat absorbing area and a heat emitting area.
