<p>Height of each corrugation is 6-9 mm. between crests; length between 2 troughs is 16-18 mm; and slope of tangent to centre of slope between crest and trough is 58-68 degrees. Preferably, heat exchanger formed by piling such plates to form tortuous path between them with liquid flow area fluctuating with repeat distance 9-14 mm.</p> |
