Bubble pumps are heat transfer devices that generate a fluid flow in a system by the lift of a steam bubble generated by the thermal energy drive. Such a heat transfer device is a heat exchange circulating-solution storage container that stores high-temperature steam after phase change from a heat exchange circulating solution heated to a high temperature and a heat exchange circulating solution. The vessel is provided with a solution delivery port and a gas-liquid two-phase fluid feed port, and the solution delivery port and the gas-liquid two-phase fluid feed port are connected to a circulation solution feed pipe that contains a solution solution feed pipe connected to the solution delivery port And a gas-liquid two-phase fluid feed pipe connected to the gas-liquid two-phase fluid inlet through the inner tube of the heat exchange circulating solution storage container. The solution sending pipe is provided with a sensible heat dissipating heat exchanger, and a heating heat exchanger is arranged in the gas-liquid two-phase fluid feeding pipe. The solution in the circulating solution input pipe generates a density difference under the action of sensible heat release heat exchanger and heating heat exchanger. When the heat load of the heating heat exchanger increases, the solution absorbs heat to generate bubbles and steam and rises above the liquid interface , So that the pressure inside the container increases, so that you can use the external power can be used to cycle solution to heat in any direction. Bubble pump is the solution in the vacuum container in the external heat generated by the bubble, the bubble rises above the liquid interface, the system pressure, so that the role of the sensible heat heat exchanger and heat exchanger to produce a density difference in the solution Using external power, the solution can be circulated to transfer heat in any direction.
