COOLING CIRCUIT OF HEAT-STRESSED STRUCTURES Russian patent published in 2015 - IPC F28F3/02 

FIELD: heating.

SUBSTANCE: cooling circuit of heat-stressed structures includes an internal shaped cover, on the outer surface of which there are ribs of the cooling circuit, an external shaped cover installed in the internal one and attached to it at tops of ribs of the cooling circuit; with that, the above covers and ribs form cooling channels. Between ribs of the cooling circuit there are hollow connection straps attaching tops of ribs to each other. Connection straps are made so that they attach groups of ribs to each other, which contain preferably three ribs each. Between the above groups of ribs, on each of their sides, there is a channel, the width of which is equal to width of a cooling channel at connection strap location point. Adjacent connection straps are located with an offset relative to each other by a value equal to width of the cooling channel at their location point; with that, width of connection straps is equal to width of the cooling channel at the connection strap location point.

EFFECT: improving stability and strength of internal and external covers of the structure.
