Cooling with free convection cooling baffles has attracted increasing interest in Sweden in recent years. Risk of surface condensation is a practical restriction. Consequently, it is required that the chilled inlet water temperature of a cooling baffle must be higher than a room air dew-point temperature, and this is at the expense of lessening the cooling capacity. In this paper, we discuss the surface condensation problem in the free convection cooling baffle system, simulate its operation under different conditions and introduce a new method to prevent dripping of condensate water using a highly absorptive paint.
