METHOD FOR STRENGTH INCREASING OF COOLING PATH OF THERMALLY STRESSED STRUCTURES Russian patent published in 2016 - IPC F02K9/64 F28F3/02 

FIELD: power industry.

SUBSTANCE: invention relates to heat-power engineering, namely to heat exchangers, and can be used during manufacturing of the cooled structures with large specific heat flows. The method of strength increasing of the cooling path of the thermally stressed structures, made by securing of the shaped internal and external shells at top of fins, made on external surface of the internal shell means surface increasing for brazing by jumpers making between the fins, their external profile corresponds to the shell profile, wherein in the said jumpers the through axial channels are made for the coolant supply. The said jumpers are made such, that by them the fin groups are connected, the groups contain preferably three fins, wherein between the said fin groups at each side the channels are made, their width is equal to width of the cooling channel at the place of jumpers. The adjacent jumpers are installed with displacement relatively to each other by value equal to width of the cooling channel at the place of their location, wherein the jumpers width is equal to width of the cooling channel at place of the jumpers installation.

EFFECT: improvement of the method efficiency.
