FIELD: heating.SUBSTANCE: heat exchange device includes elements in the form of spirally wound pipes with alternating straight and ring-shaped sections located opposite each other. The elements are installed in each other with ring-shaped sections. The straight sections of adjacent elements in the heat exchange device are located on one side, and the ring-shaped sections are located on the other side; with that, the elements in the cross section of the heat exchange device are located about its axis in a circumferential direction, with orientation of the ring-shaped sections to the above said axis. The straight sections in the elements can be located in different planes at an angle to each other. In this case, rings of the ring-shaped sections have different diameters, which are maximum in the middle of the elements and minimum in its end sections. At alignment of direction of windings of the adjacent elements, the planes that adjoin the outer side of the ring-shaped sections intersect the axis of the heat exchange device at an acute angle. At mutually opposite direction of the windings of the adjacent elements, the above planes and the axis are parallel.EFFECT: reduction of overall dimensions of the heat exchange device due to a sealed layout of adjacent elements in it; possibility of arranging it in cylindrical, annular, toroid-shaped and spherical cavities.4 cl, 14 dwg |
