Heat Exchangers
, they allow air to be passed over finned tubes containing the hot liquid. The finned tubes can be made of aluminum, copper, steel, or stainless steel, and are brazed or roller expanded to the header tank. Air is moved through the core by forced or induced-draft fans. Air-cooled exchangers are most

Seven Steps to Successful Brazing
capillary action. Proper fluxing (or a protective atmosphere) protects both the base and filler metals from oxide formation during heating. Wolverine's line of brazing fluxes, including Ultra Flux and Black Flux, are engineered to provide optimal protection. When joining copper to copper using one

When Brazing Beats Welding
in that the temperature is considerably lower and does not melt the base metals. Rather, the heat source melts a filler metal and draws it into the joint by capillary action. It creates a metallurgical bond between the filler metal and part surfaces. Like welding, joint strength often exceeds that of the individual

and a sufficient capillary pressure is maintained. The heat pipe can therefore transport a large amount of heat at high rate with a small unit size. Isobar Construction. For operating temperature ranges of 0°C to 280°C, Isobar chambers and wick structures are manufactured from pure copper and charged

Guidelines for Selecting the Right Brazing Alloy
at a temperature of almost 600 F below that of pure copper. In addition to reducing the melting point, silver also enhances capillary flow. The eutectic combination of silver and copper (72% silver, 28% copper) as discussed earlier, is often selected for furnace brazing applications where a very
