PURPOSE:To reduce the wave formation on the coolant surface due to bubbles spouting from a flow path and the upward flow of the coolant, and further improve the convective heat transfer between a vessel and the coolant, by providing a guide in the upper part of the coolant. CONSTITUTION:In the figure, the numeral 6 represents the flow path for the coolant 2 formed in a heat generator 1, and the path can gradually change the direction of the upward flow by guide plates 10 bent up, and, while preventing the loss of circulation power due to the wave formation to the minimum, is positively utilized for the downward circulation along the internal wall surface of the vessel 3. Bubbles in the upward flow are caught in the upper part of the inside of the bent guide plate 10 resulting in the generation of bubble accumulations 11. Since there is a possibility that the caught bubble accumulation 11 is not condensed, but overheated, it is allowed to escape to a gas phase space 5 in the upper part, by providing bubble release holes 13. |
