Technical Field
The invention relates to the related field of heat exchange technology, in particular to a small-sized pulse baffling conical spiral elastic tube bundle heat exchanger.

The internal heat exchange elements of the traditional shell-and-tube heat exchanger adopt a plurality of stainless steel straight tubes, so that the overall structure size is large, and the assembly flexibility is low; the heat transfer element in the traditional sleeve type heat exchanger adopts a single stainless steel straight pipe, so that the structure is simple, and the heat exchange efficiency is low. The heat transfer element of the elastic tube bundle heat exchanger is replaced by a copper tube from a traditional steel tube, so that the heat transfer tube bundle has elasticity. The fluid induced vibration enhanced heat exchange technology is adopted, namely, the fluid in the shell pass of the heat exchanger is utilized to induce the vibration of the heat exchanger tube bundle so as to achieve the purpose of enhanced heat exchange without additional energy consumption. The fluid induced vibration is a relatively potential enhanced heat exchange technology, and the design of an elastic tube bundle heat exchanger suitable for shell-side fluid induced vibration is the key. However, due to the limitation of the internal structure of the elastic tube bundle heat exchanger, the shell-side fluid cannot be guided to fully absorb heat, so that the heat transfer enhancement effect is not obvious, and the heat exchanger is difficult to realize uniform vibration of each row of tube bundles during actual operation and is easy to generate fatigue damage. Due to rapid social development, a large number of heat exchangers are large in size and mass, and the use of the heat exchangers in many high-precision technical fields is limited. Based on the problems of the heat exchanger, a heat exchanger which has a large heat exchange area, good vibration uniformity and flexible combination needs to be designed urgently.
