Detailed Description
As shown in fig. 1-3, the brazed heat exchanger with high pressure resistance and high heat exchange rate comprises a plurality of stacked plates and front and rear end plates for exchanging heat with two different heat exchange gases/fluids A, B, wherein every 2 plates are mutually matched to form a 1-2 circulation arrangement of two loops, corrugated grooves are uniformly distributed on the plates, fin-shaped protrusions 3 and reinforcing ribs 4 are sequentially arranged on wave crests and wave troughs of the corrugated grooves at intervals, the fin-shaped protrusions 3 are oppositely arranged on the same medium flow channel between the two opposite plates, and the reinforcing ribs 4 are arranged above welding surfaces of the two plates.
And the sheets are vacuum brazed by taking copper as brazing filler metal.
The reinforcing ribs 4 are of a sectional type structure.
According to the invention, the flow velocity of the medium can be slowed down and the heat exchange time is prolonged on each flow channel due to the turbulent flow effect of the fin-shaped protrusions, so that the heat exchange is more thorough, the heat exchange efficiency is better, the formation of flow channel dead zones can be avoided due to the turbulent flow effect, the dead zone sweeping is promoted, the cleaning times are reduced, and the pressure bearing capacity of the whole heat exchanger can be greatly improved due to the arrangement of the reinforcing ribs, so that the special pressure requirement is met, the application range is wider, the service life is prolonged, and the heat exchanger is worthy of popularization.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
