Experimental Study on Surface Enhanced Boiling Heat Exchanger Tubes with R134a
a typical boiling surface enhanced boiling heat exchanger tube was described and studied experimentally. When R134a is used as the refrigerant
the overall heat transfer coefficient and the outside heat transfer coefficient for this tube are 2.2-2.6 times and 1.3-1.9 times respectively as large as that of ordinary low-finned tubes at the low heat flux
