This study investigates one of the possible approaches of improvement of heat\nexchangers efficiency. Literature review shows that most approaches of\nimprovement are based on the heat transfer surface increasing and\nlaminar-to-turbulent flow transition using different types of riffles forming\nand shaped inserts. In this article, a novel approach to the heat transfer\nintensification was employed. The main hypothesis is that applying of\nmulti-chamber design of heat exchanger - ordinary shell-and-tube regions\nintersperse with common for all tubes regions - will help to improve the\nutilization of the entrance hydraulic and thermal regions thereby receive\nhigher heat transfer coefficients and higher heat capacity of the heat exchange\ndevice. To prove the hypotheses we take the following steps. Firstly,\ndevelopment of the new geometry of the heat-exchanger design - multi chambers\nconstruction. Secondly, proving of the higher efficiency of novel design\ncomparing to ordinary design by analytical calculations. Thirdly, numerical\nsimulation of the heat exchange process and fluids flow in both types of heat\nexchangers that proves the analytical solution.\n
