Abstract
A self purging fin cooler for use with a glass fiber forming bushing assembly is disclosed. A fin cooler header block is provided with a flow channel for coolant flow and a separate flow channel for cleaning liquid flow. A plurality of cleaning liquid distribution passages extend from the cleaning liquid flow channel to spray nozzles positioned between adjacent cooling fins that extend outwardly from the header block. Each spray nozzle produces a flat, fan shaped spray of cleaning liquid which removes contaminants that accumulate on the tops and sides of the cooling fins. A flow control valve assembly and frequency and duration timers are utilized to provide a controllable cleaning liquid spray frequency and duration. During non-spray periods a low volume of cleaning liquid to the spray nozzles insures that the nozzles will not become clogged.
