The invention relates to heat engineering, in particular to recuperative heat exchange apparatuses. A heat exchange apparatus has a body with a nozzle for supply – discharge of media and bundle of heat transfer tubes fixed in tube plates. The body consists of at least two coaxial parts that are connected to each other in sequence through elastic sealing pads, this makes it possible to obtain having dismantled part of the body access to inter-pipe cavity for the apparatus servicing. The tube bundle has not less then one spacer partition that is in places corresponding to arrangement of joints of parts of the body, at that the outer surface of the body is in contact with elastic sealing pads. This excludes bypass flows with provision of increase of heat effectiveness of the apparatus. |
