The purpose of this study is to experimentally figure out thermal performances of a newly developed wavy patterned heat plates(first heat plates) which are known to have better thermal performances than the conventional heat plates. Three types of products were made with high and low chevron angled plates. The test results show that overall heat transfer coefficients and pressure drops increased with flow rates and chevron angles just like other studies. Another purpose of this study is to find a way to reduce pressure drops while maintaining or even improving the heat transfer characteristics of the first heat plates. Research on optimization of the distribution area on the heat plate to achieve the even fluid distribution was conducted, and then the second heat plates were developed to reflect the research results. Another new three types of products with the second heat plates were manufactured and tested, too. The test results of the second heat plates were compared with those of the first heat plates to find out how the distribution area contributed to the thermal performances of the heat plates. The comparison showed that distribution area optimization could affect thermal performances of the high chevron angled plate positively, but the low chevron angled plate had little effect from the optimization. This is considered to be because the low chevron angled plate itself has a characteristic that the pressure drop is small.
