<p>A corrugated core structure for a heat exchanger in the form of a corrugated plate, the walls of the corrugations defining passages for the flow of a heat-trans-fer agent to pass therethrough. The walls are provided with pairs of extending along the length thereof projections and recesses successively separated by smooth wall portions to effect successive throttling of the heat-trans-fer agent flow. Each smooth wall portion is of a length essentially below five values of the hydraulic diameter of the smooth portion of the passage. The inner curvature radius of the vertex of the corrugation is essentially below a difference between one fourth of the pitch of the corrugations and half the wall thickness thereof, the projections and recesses on the walls of the corrugations having a length capable to ensure an intensified heat transfer process.</p> |
