<p>Proposed invention belongs to heat exchanging equipment and can be used in household and in various ranches of industry and especially where its weight and size are limited. Heat exchanger of "tube-in-tube" type contains two tubes (1 and 2) located with a gap between them. Inlet fitting for liquid to be heated (5) is located from the side of heat carrier outlet (4) and outlet fitting for liquid to be heated (6) is located from the side of heat carrier inlet (3), while the heat exchanger is made in the form of spiral helix. The heat exchanger proposed allows, due to changing its shape, to decrease its weight and length, to simplify its design, and, due to eliminating additional elements that increase the surface of heating, but at the same time it preserves high productivity of heat exchanger.</p> |
