[0002] Heat exchanger, also known as heat exchanger, is an energy-saving device that transfers heat between two or more fluids at different temperatures. Its working principle is to transfer part of the heat of hot fluid to cold fluid to meet the needs of process conditions. It is also one of the main equipment to improve energy utilization. Heat exchangers play an important role in many industrial productions such as chemical, petroleum, power, food, etc., and are widely used in other fields.

[0003] In the working process of the existing tubular heat exchanger, the fluid is split and then passes through the heat exchanger to complete the heat exchange. In this process, the heat exchange area between the fluids is increased by the split tube. However, since the hot fluid has a short travel in the heat exchanger, it is often discharged without sufficient heat exchange, resulting in low heat exchange efficiency of the heat exchanger. Therefore, an efficient and stable heat exchange type heat exchanger is proposed. Utility Model Content
