Heat transfer temperature difference is one of the important factors affecting the heat transfer performance of spiral plate heat exchangers. In a spiral plate heat exchanger, the magnitude of the temperature difference directly determines the heat transfer efficiency. When the temperature difference between the heat source and the cold source is large, the speed of heat transfer will be faster and the heat transfer efficiency will be higher. Therefore, when designing and selecting a spiral plate heat exchanger, the influence of heat transfer temperature difference should be fully considered to achieve good heat transfer effect.

However, excessive heat transfer temperature difference may also cause the equipment to be affected by thermal stress, thereby affecting its service life. Therefore, in practical applications, spiral plate heat exchangers should be selected and used reasonably to avoid the adverse effects caused by excessive heat transfer temperature differences. At the same time, in order to improve heat transfer efficiency, other measures can be taken, such as improving equipment design, using enhanced heat transfer materials, and surface treatment.
