Problems solved by technology

Therefore, it is necessary to evaluate the performance of the heat exchanger. However, there is no high-temperature heat storage measurement platform with a power greater than 10MW in the prior art. In addition, the performance of some large heat exchangers can only be calculated and evaluated by numerical simulation.
