Designing any refrigeration system is critical because it should be more efficient than the previous designs. In this article, a bubble pump which is an essential equipment of an integrated cooling system, has been designed. The design conditions were assumed that a hot surface released different amounts of heat 550 W and 1500 W is to be cooled and maintain the temperature under the desirable limit. The experiments have been conducted under the atmospheric pressure used many configurations such as a different number of 8 mm diameter lifting tubes from one to four tubes and different submergence ratios 0.3, 0.4, and 0.5. The efficiency has been calculated, and at the last step, the conclusion has been extracted that the slug flow pattern could be noticed in the experiments as the desired flow type where the maximum mass flow rate is about 63 g/s at a configuration of four lifting tubes and the heat power is 1500 W. It was concluded that the performance was directly proportional to the submergence ratio and lifting tubes.
