Heat exchange

The liquid heat exchangers we have built and patented are more efficient than the currently used “snake-type” models by 3,5-6 times (refer to the diagram №1) details »».

In the existing and newly designed heat exchanger equipment for liquids, to intensify heat transfer, artificial turbulization of a heat-transfer agent is used with the application of rod-like, intrachannel and surface intensifiers having special-shape turbulence stimulating inserts or bundles of smooth and rough tubes of even or different diameters or tubes of a variable cross-section having different configurations: cylindrical, conical, conical-cylindrical, etc., exposed to a transversal flow. Said variants are hard to be produced for requiring a lot of special equipment. In our structure of a liquid heat exchanger, the turbulization of the flow inside the heat exchanger is much higher thanks to our patented technology for manufacturing channels that enables to rise the heat transfer ratio by 2 times, with a lower fabrication cost compared to generally known welded constructions of heat exchangers, often called “snake-like”.
Our air radiator provides, for the same air consumption and the same heat load as for a pin radiator, a 2.15 to 6.92 times higher (refer to the diagram №2) temperature difference between the inlet and the outlet, which enables us to suggest innovative technical solutions for many fields:

Natural (free) convection. The experiment showed:
At a heat load of 9 Watts distributed on identical surfaces (40х40 mm) of tested heat exchangers having the base thickness of 3 mm (our L heat exchanger and a known rod heat exchanger). At the ambient temperature of 21oC, in the case of our L heat exchanger and of the rod heat exchanger, the temperature sensors being glued between the heat sink elements of both heat exchangers tested, our L heat exchanger showed a temperature 19 degrees lower than that of the rod heat exchanger.
