[0024] A further optimization scheme is to generate electricity by utilizing hot spring thermal energy through a pulsating heat pipe 2.1. The thermovoltaic power generation device 2 includes a pulsating heat pipe 2.1, and the pulsating heat pipe 2.1 includes an evaporation section, an insulation section, and a condensation section; the evaporation section of the pulsating heat pipe 2.1 is arranged in the hot water of the hot spring power generation cell 1.1, and the condensation section of the pulsating heat pipe 2.1 is provided with a cold water radiator 2.5, and an ordinary valve 1.8 is installed at the inlet end of the cold water radiator 2.5; a plurality of thermovoltaic power generation chips 2.4 are installed between the condensation section of the pulsating heat pipe 2.1 and the cold water radiator 2.5, and the two sides of the thermovoltaic power generation chip 2.4 are respectively fitted with the condensation section of the pulsating heat pipe 2.1 and the cold water radiator 2.5; the water outlet of the cold water radiator 2.5 is connected to the hot spring therapy pool 1.2 through a temperature control valve system.

[0025] According to a further optimization scheme, a microscopic capillary structure 2.1.1 is arranged on the inner wall of the pulsating heat pipe 2.1, and the microscopic capillary structure 2.1.1 is arranged along the axial direction of the pulsating heat pipe 2.1, so as to improve the heat extraction performance of the pulsating heat pipe 2.1 through capillary force.

[0026] To further optimize the solution, in order to ensure that the thermovoltaic power generation chip 2.4 can fully fit with the pulsating heat pipe 2.1, increase the heat transfer area, and effectively increase the power generation, copper sheets 2.2 are fitted on both sides of the condensing section of the pulsating heat pipe 2.1, and the thermovoltaic power generation chip 2.4 is fixedly installed on the copper sheet 2.2 by bolts 2.3, and the side of the thermovoltaic power generation chip 2.4 away from the copper sheet 2.2 is fitted with the cold water radiator 2.5.

[0028] To further optimize the solution, in order to achieve uninterrupted power generation in the hot spring at a stable temperature, the temperature control valve system includes a cold water temperature control valve 1.4, a hot water temperature control valve 1.5 and a temperature sensor 1.6. The cold water temperature control valve 1.4 and the hot water temperature control valve 1.5 are both installed on the thermal insulation wall 1.3.

[0030] The combined system of geothermal hot spring pool thermovoltaic power generation and water temperature control provided by the present invention has the following working principles:

[0031] The present invention utilizes a pulsating heat pipe 2.1 to absorb heat energy from the initial high-temperature water of a hot spring, and transfers the heat to a thermovoltaic power generation chip 2.4 to generate electricity. At the same time, a temperature control valve system is used to keep the temperature of the hot spring water at a moderate level. Compared with a traditional heat pipe, the designed pulsating heat pipe 2.1 and the thermovoltaic power generation chip 2.4 have a larger heat transfer area. The pulsating heat pipe 2.1 has a microscopic capillary structure 2.1.1 that can extract more heat energy, effectively increase power generation, and has good thermal conductivity and corrosion resistance. The equipment can operate stably for a long time.

[0032] Thermovoltaic power generation chip 2.4 uses temperature difference to generate electricity. The initial high temperature of the hot spring and the cold water of the radiator provide a stable temperature difference. Thermovoltaic power generation chip 2.4 installed on the pulsating heat pipe 2.1 can effectively convert this temperature difference into electricity to power the hot spring resort street lights, audio equipment and tourists' mobile phones.

[0033] The design of the entire system takes into account factors such as the change in hot spring water temperature and ambient temperature. A temperature insulation wall 1.3 and a temperature control valve system are set up in the hot spring pool 1 to ensure that the equipment can operate stably and efficiently under various conditions, monitor the hot spring water temperature and power generation efficiency in real time, and automatically adjust the flow of hot and cold water and the operating status of the equipment to ensure the best performance of the system. When there are no tourists late at night, the temperature control valve system can be closed to maximize the use of hot spring heat energy.

[0034] The combined system of thermovoltaic power generation and water temperature control for geothermal hot spring pools provided by the present invention is mainly aimed at the hot spring geothermal development of hot spring resorts. It innovatively integrates pulsating heat pipes 2.1 and thermovoltaic power generation technology, fully utilizing the high-temperature thermal energy contained in natural hot springs. Before the temperature needs to be lowered to a comfortable temperature for the human body, the natural temperature difference between the natural hot spring and the regulated cold water is utilized to the maximum extent. The pulsating heat pipes 2.1 are utilized to effectively increase the heat exchange area and the amount of heat taken. At the same time, the thermovoltaic power generation chip 2.4 is used to directly convert the hot spring thermal energy into electrical energy, providing charging and power supply services for the hot spring resort infrastructure, electronic entertainment equipment, etc., and simultaneously realizing the dual functions of hot spring power generation and bathing water temperature control, thereby improving the comprehensive utilization efficiency of hot spring thermal energy and creating a green, friendly and sustainable hot spring resort environment.

[0035] The present invention innovatively proposes pulsating heat pipe technology, which does not require deep geothermal wells. It can flexibly increase loops according to actual needs and arrange them around the hot spring pool, thereby increasing the heating area of ​​the evaporation section of the pulsating heat pipe, and then increasing the heat extracted by the pulsating heat pipe, which is suitable for various hot spring resorts. Compared with the traditional system, the loop pulsating heat pipe of the present invention does not need to rely on special geothermal wells, and can directly draw heat from shallow hot spring pools. The construction cost is low and it can effectively increase geothermal power generation. In addition, the present invention also has the function of adjusting the temperature of the hot spring pool in real time. There is no need for an external cold source. It makes full use of the temperature difference between the cold and hot sources before adjusting the water temperature to achieve power generation, and then adjusts the temperature of the hot spring pool, further optimizing the stability and efficiency of the power generation process. Thermovoltaic power generation can be used for entertainment equipment such as music and street lights in hot spring resorts, saving energy in hot spring resorts and promoting the sustainable development of the hot spring industry.

[0036] The above are only preferred specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
