The boiling cooling apparatus is comprised of a heat generating device which is completely immersed in a liquid coolant which partially fills a sealed container. At least one vertically extending passage is provided through the heat producing device whereby ascending bubbles formed in the passage by the heat transfer from the heat generating device to the liquid medium cause an upward current flow through the passage. A plurality of current flow control plates are provided for diverting the upward flow of liquid coolant laterally and downwardly along the sides of the container to provide convection cooling of the liquid and directing the downward flow of liquid coolant into the lower end of the passage in the heat generating device to provide a cyclic flow of the cooling liquid.
