Abstract
A heat exchange device may include a first pipe including a first inlet, a first outlet, and a first sidewall extending therebetween; a second pipe including a second inlet, a second outlet, and a second sidewall extending therebetween; and a plurality of dimples extending between the first sidewall and the second sidewall. The second sidewall may surround and extend about the first sidewall, the first sidewall may define a first fluid passage configured to permit flow of a first fluid, and the second sidewall and the first sidewall may define a second fluid passage configured to permit flow of a second fluid.
