The invention relates to area of heat power engineering, in particular to recuperative heat exchange apparatuses. A heat exchange apparatus has a tube bundle placed in the body with tube for supply and tube for discharge of heat carrier of tube side and with tube for supply (discharge) of heat carrier of shell side placed at opposite ends of the body. The body is equipped with two tubes for supply and two tubes for discharge of heat carrier of shell side. Tubes for supply (discharge) and discharge (supply) of heat carrier of shell side are placed in pairs at opposite ends of the body. The invention provides comparable hydraulic resistances in tube side and shell side in case of substantial exceeding flow rate of heat carrier in shell side over flow rate of heat carrier in pipe cavity and preservation of thermal effectiveness of apparatus. |
