HEAT EXCHANGER Russian patent published in 2008 - IPC F28D7/06 

FIELD: thermal physics.

SUBSTANCE: heat exchanger consists of a matrix from two plate holders in a case, including tubelet panels made from a set of U-shaped pipes with different bending radii. The plate holders are turned 90° from each other. The straight sections of the tubelet panels of one plate holder are put in the gaps between adjacent straight sections of the tubelet panels of the other plate holder. The pipes are joined to collectors for input and output of the internal heat carrier. The collectors are fitted inside the case, are not joined to each other and are joined to the corresponding input and output channels, in the form a T-joint with separation or fusion of the stream of the internal heat carrier for two plate holders at the same time. In the U-shaped sections of the tubelet panels, between the case and the pipe matrix, there are anti-balancing devices. The anti-balancing devices used are metallic wire nets with a zigzag shape in one or more layers. Plate holders are put mutually perpendicular. The straight sections of the pipe plate holders are put between adjacent straight sections of the tubelet panels with formation of a common lattice surface.

EFFECT: intensified heat exchange and smaller dimensions of the heat exchanger.
