The Rankine cycle, as a common way of solar power generation, is receiving more and more attention. However, the adoption of a mechanical booster pump in the conventional Rankine cycle affects the compactness of the power system. Based on this, a new booster cavity is proposed in this paper for an integrated thermal-electric conversion device, to replace the mechanical booster pump. For this proposed structure, the pressurization of low pressure condensate liquid is achieved by utilizing the internal energy of high temperature and high pressure vapor. To verify its feasibility, the theoretical description of the physical process, mathematical modeling, simulation analysis, and experimental verification of the structure are presented in this paper. It can be found that the structure is workable, and no power transmission from an external energy source is required for the thermal-electric conversion device adopting this structure. Although the conversion efficiency of the proposed cycle is 15.23%, which is slightly lower than the 15.71% efficiency of the conventional Rankine cycle under the same operating condition, it is a true thermal driven power generation, which enables a more compact system.The Rankine cycle, as a common way of solar power generation, is receiving more and more attention.

太阳能热电转换装置增压腔可行性分析

兰金循环作为一种常见的太阳能发电方式，正受到越来越多的关注。然而，在常规兰金循环中采用机械增压泵影响了动力系统的紧凑性。基于此，本文提出了一种新型的增压腔，用于集成热电转换装置，以取代机械增压泵。对于这种提议的结构，低压冷凝液的加压是通过利用高温高压蒸汽的内能来实现的。为了验证其可行性，本文对结构的物理过程进行了理论描述、数学建模、仿真分析和实验验证。可以发现结构是可行的，采用这种结构的热电转换装置不需要外部能源的电力传输。虽然提出的循环的转换效率为 15.23%，略低于相同运行条件下传统朗肯循环的 15.71% 效率，但它是真正的热驱动发电，可以实现更紧凑的系统。循环作为一种常见的太阳能发电方式，正受到越来越多的关注。然而，在常规兰金循环中采用机械增压泵影响了动力系统的紧凑性。基于此，本文提出了一种新型的增压腔，用于集成热电转换装置，以取代机械增压泵。对于这个提议的结构，利用高温高压蒸汽的内能实现低压冷凝液的增压。为了验证其可行性，本文对结构的物理过程进行了理论描述、数学建模、仿真分析和实验验证。可以发现，该结构是可行的，采用该结构的热电转换装置不需要外部能源的电力传输。虽然建议循环的转换效率为 15.23%，但... 并在本文中介绍了结构的实验验证。可以发现，该结构是可行的，采用该结构的热电转换装置不需要外部能源的电力传输。虽然建议循环的转换效率为 15.23%，但... 并在本文中介绍了结构的实验验证。可以发现，该结构是可行的，采用该结构的热电转换装置不需要外部能源的电力传输。虽然建议循环的转换效率为 15.23%，但...
