Abstract

A metal heat transfer surface is treated to provide thereon a plurality of microscopic areas, some (e.g. 10) having hydrophilic chracteristics and being interspersed with others (e.g. 20) having hydrophobic characteristics; the latter providing a plurality of bubble-forming points for a vapourizing liquid, and the hydrophilic areas constituting growth areas for the bubbles. It is stated that on a metal heat exchange surface so treated, a bubble (25) forming on one of the hydrophilic areas will quickly assume a spherical shape (26) and will then expand to a size (such as indicated at 27), many times the size of the original formation. The metal surface may be pitted by any known chemical, electrical, accoustical or thermal means. In one example a stainless steel strip was etched by dipping for 5 to 10 mins. in sulphuric acid at about 80 DEG C, washed in water and then dipped for about 10 mins. in a dilute solution of ferric chloride. Finally the strip was coated by brushing with an epoxy resin mixed with a hardener and thinned by a solvent. After curing for 24 hours the strip surface was sanded leaving only the pockets formed by pitting, filled with resin. In another example a sheet of medium grade emery paper was sandwiched between a strip to be treated and a backing strip and the lamination so formed was then hammered to cause the emery grit to indent the strip under treatment. After cleaning, a coat of polytetrafluorethylene enamel was brushed on to the strip and then wiped off leaving the identations filled with enamel. The strip was then baked at 650 DEG F to cure the enamel. In a further example a cleaned smooth strip of stainless steel was sprayed with enamel from a perfume atomizer, the spray being directed into a rising air stream so that only the smallest droplets are carried on to the strip which is suspended across the air stream.
