INFLUENCE OF CLEARANCE BETWEEN RIB POINTS ON HEAT TRANSFER OF HEAT EXCHANGERS BEING ASSEMBLED WITH THE HELP OF FLAT PIPES WITH CUT RIBBING
Abstract
The paper proposes an experimental determination of an influence of a clearance value on the intensity of heat transfer of the heat exchanger ribbed surface of the heat exchangers that allows to determine a value of heat transfer decrease caused by a deviation of rib height from the calculated value. It has been shown that occurrence of a clearance between rib points in the core of a heat exchanger assembled with the help of flat pipes with cut ribbing leads to significant decrease in heat transfer efficiency.
