Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchange equipment, and in particular relates to a mobile modular pharmaceutical machinery heat exchange device. Background Art

[0002] Pharmaceutical machinery heat exchange devices are often large in size, heavy in weight, and difficult to move and install. These shortcomings are mainly due to the following aspects: First, in order to improve the heat exchange efficiency, the pipes and heat transfer surface areas inside the heat exchange device are designed to be more complex, which makes the structure more bulky. Secondly, in order to ensure the safety and stability of the device under high temperature and high pressure conditions, high-strength materials and thickened walls must be used, which further increases the weight of the device. In addition, the pharmaceutical industry has high requirements for the hygiene of equipment, which usually requires frequent cleaning and maintenance. The design needs to consider structures that are easy to disassemble and clean, which will also affect the portability of the device. Conventional countermeasures mainly include: optimizing the design of the heat exchanger, using more efficient heat exchange tubes and heat transfer surfaces, such as using bellows, spiral tubes, etc., to improve the heat exchange efficiency and reduce the size of the equipment. Secondly, try to use new lightweight materials, such as high-performance composite materials, to replace traditional metal materials to reduce the weight of the equipment. In addition, through modular design, large heat exchange devices are split into multiple small units for easy transportation and installation.

[0003] However, these methods also have some drawbacks. Although optimizing the design and using high-efficiency heat transfer elements can improve efficiency and reduce volume, they often increase the complexity and cost of design and manufacturing. The use of new lightweight materials may have problems of high cost and immature technology, and the reliability under high temperature and high pressure conditions needs further verification. Although modular design can improve flexibility, the sealing and reliability issues of the connection parts may lead to additional maintenance and failure risks. Therefore, we hope to design a heat exchange device with a new structure to solve this problem. Utility Model Content
