متن کاملEnergy Conservation Potential of the Heat Pipe Heat Exchangers: Experimental Study and Predictions
The energy conservation potential of the heat pipe based heat exchangers (HPHXs) was studied in this research. To this end, a typical climate chamber as the representative of an air conditioning system was established. The performance characteristic of a typical eight-row HPHX was obtained based on the one week operation (168 h) to determine the performance characteristic curves. The coil face ...
متن کاملReview of Fractal Heat Exchangers
Nature has inspired many scientists and engineers to solve problems through observation and mimicry. One such example is heat transfer enhancement. The enormous natural heat and mass transfer phenomena have led engineers to seek solutions to heat transfer enhancement problems from nature. Fractal geometries are found in respiratory and vascular systems of plants and animals, such as blood vesse...
