Measurements of heat transfer coefficients from supercritical fluid flowing in vertical mini channels with constant wall temperature

Currently, efficient heat transmission for compact electronic elements is an essential matter. It needs a sink with liquid cooling scheme that meets these demands as much feasible. The dimensions of 50.8 × 40.6 5.5 mm were adopted features transfer well
