Based on the research and analysis of the heat exchange process.

Based on the research and analysis of the heat exchange process of the 1MW solid electric heat storage heat exchange system, the minimum heat exchange temperature of the hot air is analyzed from the efficiency of the fan and the structure of the heat exchanger itself; when designing the heat exchanger, it is To ensure heat transfer, the highest outlet temperature parameter should be used as the benchmark; overall and parametric performance analysis should also be performed based on the heat exchanger design of the 1MW unit. In addition, according to the heat transfer characteristics of the finned tube heat exchanger, the effects of the tube spacing, fin height, windward area and fin pitch on the heat transfer area and the outlet air pressure of the finned tube heat exchanger were analyzed. In this paper, by simulating the actual operating conditions of the gas turbine intake heater, the three-dimensional deformed tube is used in the gas turbine intake heater, and the heat transfer performance in the tube is studied. It is found that compared with the round tube, the heat transfer coefficient in the three-dimensional deformed tube can be Increased by 31.6%. The heat exchangers using three-dimensional deformed tubes and H-shaped finned tubes were tested, and the results showed that the shell-side heat transfer coefficient of the three-dimensional deformed tube heat exchanger was significantly better than that of the H-shaped finned tube heat exchanger, and the air flow rate was higher than that of the H-shaped finned tube heat exchanger. The higher the temperature, the more obvious the advantage, but at the same time the pressure drop will also increase; with the change of the air flow rate, the comprehensive heat transfer performance of the three-dimensional deformed tube heat exchanger is better than that of the H-shaped finned tube heat exchanger.
