Description

Phase-change enhanced heat transfer and exchange system Technical Field The utility model relates to the technical field of heat exchangers, in particular to a phase-change enhanced heat transfer and heat exchange system. Background Phase change enhanced heat transfer is a technique that enhances heat transfer through a change in the phase state of a substance. During such heat exchange, the fluid may undergo a phase transition, such as from a liquid state to a gaseous state, or from a gaseous state to a liquid state, as it passes through the heat exchanger. The phase change process is accompanied by a large amount of latent heat release or absorption, and the heat exchange of the latent heat can remarkably improve the heat exchange efficiency. When fluid exchanges heat through the heat exchanger, the fluid often enters the heat exchanger at a faster flow rate, the flow of the fluid is blocked by the twisted and bent coil pipe in the heat exchanger, the flow rate of the fluid is reduced, so that the residence time of the fluid with heat in the heat exchanger is prolonged, the fluid can collide with the heat exchanger when entering the heat exchanger due to the fact that the fluid still has a large amount of mechanical potential energy, and the vibration of the heat exchanger is transmitted to a structure loaded with the heat exchanger, so that the structural firmness of the heat exchanger is influenced. Therefore, a phase-change enhanced heat transfer and exchange system is provided to solve or alleviate the above problems.
