| 摘要 |
A heat exchanger for transmitting thermal energy from one moving fluid to another of the type having a casing housing a thermal transfer core, the core including a folded sheet of heat conductive material defining adjacent fluid flow passages, the individual fold sections of the sheet having a multiplicity of pairs of dimples formed therein, each dimple pair including a raised dimple and an adjacent depressed dimple, the height of each dimple being substantially equal to one-half the width of the fluid flow passages. The dimple arrangement provides a relatively low pressure drop for the fluids passing through the fluid flow passages.
