Plate heat exchangers are widely used in electronic packaging for many years. The corrugated channels on plates effectively enhance the turbulence of flow boiling and complicate the prediction of pressure drop. This paper presents a brief review about the influence factors of frictional pressure drop during flow boiling in plate heat exchangers. This paper collected many of the experiment data of the frictional pressure in order to develop a new correlation of the plate heat exchangers . Experimental data points of frictional pressure drop were collected from previous literatures to develop a general correlation. The database contained 701 data points, covering a wide area of the data, which including eight refrigerants, mass flux range from  5.5 to 137 kg m^-2^ s^-1^, heat flux 0-30 kW m^-2^, vapor quality 0.07-0.95, saturation pressure 0.11-2.7 MPa, chevron angle 30°-70° and hydraulic diameter 1.7-5.4 mm. In this work, several existing correlations were compared with the database, and all of them seem fail to give an acceptable prediction. A new correlation was proposed with multiply regression analysis in terms of two-phase Fanning friction factor. The new method showed good agreement and predicted 58.1% and 86.9% of points within ±30% and ±50% errors, respectively.

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
