| Abstract: | Lots of experimental research has been done on the new double-flow lubricating-oil cooler which has mixed tube bundles, and it is found that such cooler has very strong heat transfer ability. The main approaches to miniaturize lubricating-oil cooler are discussed in this paper. Under the same mass flow condition, experiments were done to compare the new double-flow lubricating-oil cooler which is made of integral pin-fin tubes with the plain lubricating-oil cooler with segmental baffles. The experiment shows that the former one has the highest heat capacity in unit volume, relatively lower pressure drop, and superior integrated performance. |
