AIR COOLER Russian patent published in 2021 - IPC F28D5/00 F28D1/03 

FIELD: engineering.

SUBSTANCE: invention relates to the field of heat engineering and can be used in air cooling devices. An air cooling apparatus including corrugated plates interconnected in pairs, forming alternating channels for the passage of cooling air and sealed channels for the passage of the cooled product, collector chambers, a fan with an electric motor, is made so that the sealed channels for the passage of the cooled product are connected by taps to the collector cameras and placed in the casing; the casing is open from the side of the cooling air inlet, one or more fans with an electric motor are installed on the opposite side of the casing. The corrugations on the plates have a triangular or semicircular cross-section; on the surfaces of the walls of the corrugated plates facing the channels for the passage of cooling air, there are elements of discrete roughness in the form of protrusions or depressions; the branches connecting the sealed channels for the passage of the cooled product with the collector chambers are made with connectors.

EFFECT: increasing the efficiency of the device, manufacturability of its manufacture.
