[0002] At present, thermal semiconductor thermoelectric power generation technology has been widely studied and applied. However, the simulation and experiment of semiconductor thermoelectric power generation in oil wells or other underground high-temperature environments still face some challenges and difficulties.

[0003] Existing experimental devices are often of general design, which makes it difficult to conduct simulation experiments on special shapes such as cylindrical pipes, limiting the research and optimization of such devices. Conducting experiments underground is costly, difficult, and time-consuming, requiring a professional team and a large amount of resources, which limits the scale and frequency of experiments, as well as the testing of different parameters.

[0004] At present, there are no relevant literature and experimental devices for simulation and experimental devices of semiconductor temperature difference power generation in oil wells or other high-temperature environments underground, and there is a lack of in-depth research and exploration in this field. Utility Model Content

[0005] In view of the above-mentioned technical problems of high cost, great difficulty and long time consumption in underground experiments, the utility model provides a pipeline semiconductor temperature difference power generation simulation and experimental device.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A pipeline semiconductor temperature difference power generation simulation and experimental device includes a polygonal oil pipe, a thermovoltaic power generation chip, a sleeve, a top flange and a bottom flange. A plurality of thermovoltaic power generation chips are arranged and installed on each side of the polygonal oil pipe. The sleeve is arranged outside the polygonal oil pipe. A top flange is installed on the top of the polygonal oil pipe, and a bottom flange is installed on the bottom of the polygonal oil pipe.

[0008] Flanges are provided on the top and bottom of the polygonal oil pipe, and a plurality of oil pipe flange fixing holes and an oil pipe flange water through hole are provided on the flange of the polygonal oil pipe.

[0010] The top flange and the bottom flange are respectively provided with a plurality of inner fixing holes, a plurality of outer fixing holes, an inner water hole and an outer water hole. The top flange is assembled with the top of the oil pipe and the casing, and the bottom flange is assembled with the bottom of the polygonal oil pipe and the casing. The oil pipe flange fixing holes on the polygonal oil pipe are correspondingly connected with the inner fixing holes of the top flange and the bottom flange, and the casing flange fixing holes on the casing are correspondingly connected with the outer fixing holes of the top flange and the bottom flange.

[0011] The oil pipe flange water holes on the polygonal oil pipe are correspondingly connected to the outer water holes of the top flange and the bottom flange, and the inner water holes of the top flange and the bottom flange directly lead to the inner space of the polygonal oil pipe.

[0012] A hollow heating tube is installed on the bottom flange, and a heating rod is arranged inside the hollow heating tube.

[0013] The thermovoltaic power generation chip is fixed to the outer surface of the polygonal oil pipe by means of heat-conducting adhesive.

[0014] The polygonal oil pipe is connected to a water storage tank, the water storage tank is connected to a steam generator, the steam generator is connected to a steam storage tank, and the steam storage tank is connected to the polygonal oil pipe.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. The utility model provides simulation and experimental research capabilities for semiconductor power generation technology. As a simulation and experimental device, the device provides a convenient and cost-effective means for conducting downhole temperature difference power generation research in ground laboratories. In ground laboratories, different temperature difference conditions, pipe string shapes and other parameters can be simulated to better understand and optimize the design and performance of downhole temperature difference power generation devices.

[0019] 2. The utility model saves costs and improves power generation efficiency. The design of the device can not only study methods to improve the efficiency of semiconductor temperature difference power generation, but also save experimental costs and time. Compared with experiments conducted underground, the simulation and experimental devices in the ground laboratory are lower in cost, more convenient to operate, and not restricted by the underground environment. Experimental research under different conditions can be conducted more flexibly, thereby accelerating the R&D cycle and reducing R&D costs.

[0020] 3. The utility model realizes efficient power generation under different environments and conditions. The simulation and experimental device utilizes the combined design of polygonal tubing, thermovoltaic power generation chip and casing to effectively utilize the underground temperature difference environment to achieve efficient power generation. The design of polygonal tubing increases the surface area and improves the heat exchange efficiency, while the thermovoltaic power generation chip directly converts the temperature difference into electrical energy, so that the device can stably generate electricity in the underground environment.
