FIELD: heating; engines and pumps. ^ SUBSTANCE: in both embodiments instrument contains fans for outer intertubular cooling medium feeding, mainly it is air, body implemented as sectionalised with at least two heat exchanging sections. Every section includes pressure vessel for intratubal medium, mainly it is gas, implemented as multiserial single-pass fascicle of finned tubes, connected with chamber of gas input and output and through them with collectors of gas feeding and withdrawal. Finned tubes are located in fascicle with offset in every row concerning tubes in adjoining rows, and rows of tubes are separated from each other by dissociating elements implemented as plicate plates with alternating on plate length salient and concave areas, which form support point for tubes of fascicle height adjoining rows. Configuration of plicate dissociating element accepted such as diametric line of top concave areas are located with respect to plane which passes through appropriate diametric lines of bottom concaves areas of element, in the high-altitude range of amounts, defined by specified relationship. According to the first version of implementation instrument gas air cooling is outfitted by aero-clear sun screen of sloping plates, located with orientation of its longitudinal axes in the line of east-west azimuthal deflection from this direction in plane in the range from -35° till +35°. ^ EFFECT: increasing of heat exchange efficiency; increasing calorific power of instrument and rising of instrument service life. ^ 22 cl, 27 dwg |
