With the rapid development of the pharmaceutical industry, the demand for heat exchangers in the production process of pharmaceutical manufacturing enterprises is increasing. In particular, some pharmaceutical enterprises in new industrial areas in the south often fail to provide 24 hours of boiler steam supply due to production condition limitations. During non-production periods, the production cost of boiler steam is increased significantly, not only is a great amount of human resources (such as management personnel, production personnel and safety personnel) required to be input, but also the consumption of steam is reduced, and the operation loss can even exceed the demand of process equipment, which brings great economic burden to enterprises.

In addition, due to the particularities of the pharmaceutical industry, the pharmaceutical water requires a strict control of temperature to prevent the occurrence of temperatures below GMP regulations, affecting product quality. Therefore, how to maintain the constant temperature control of the water for injection during the period of no steam supply is a urgent problem to be solved by pharmaceutical enterprises.

Conventional heat exchangers typically employ a single steam heating process, which, although to some extent, can meet the needs of pharmaceutical enterprises, is of limited use in situations where a stable steam supply is not available. Meanwhile, some traditional heat exchangers have defects in structural design, material selection, cleaning maintenance and the like, and are difficult to meet the requirements of pharmaceutical enterprises on sanitation, safety and reliability.

Meanwhile, the inlet end 31 and the outlet end 32 of the U-shaped heat exchange tube group 3 are connected to the end plate assembly 1, and the structural layout ensures that the overall structure of the heat exchanger is more compact and is convenient to install and use.

Similarly, the pharmaceutical water outlet pipe 122 corresponds to the outlet ends of all the heat exchange tubes 311, so that the pharmaceutical water after heat exchange can smoothly flow out, thereby completing the whole heat exchange process. Through the design, the heat exchanger can meet the requirement of pharmaceutical water temperature control in the pharmaceutical process, and can ensure the flow uniformity and heat exchange efficiency of the pharmaceutical water.
