Description

TECHNICAL FIELD

[0001] The utility model relates to heat exchanger technical field, concretely is a kind of heat exchanger of multiple unit heat exchange area. BACKGROUND

[0002] Traditional heat exchanger has significant limitations.On the one hand, its structure is mostly single heat exchange tube layout, which limits the heat exchange area. In industrial production scenarios, it is difficult to quickly and effectively handle a large amount of heat exchange, such as heat transfer problems in chemical production, which can lead to reduced production efficiency and safety hazards. Moreover, the structure of the traditional heat exchanger lacks flexibility, and its heat exchange units cannot be flexibly adjusted as needed. For example, heating, ventilation and air conditioning systems have different demands for heat exchange area in different seasons, and the traditional heat exchanger cannot adapt to such changes, resulting in energy waste or poor heat exchange effect. In addition, the traditional heat exchanger requires complex pipe connections and customized supports during installation, which is difficult and costly to install. Moreover, due to the complex internal structure, it is not easy to disassemble, making maintenance and cleaning very troublesome. More importantly, conventional heat exchangers are single cold and hot source channel heat exchangers. When the terminal use equipment requires a large temperature control range, the heat exchange area calculated under the worst working conditions may not be accurate when used at minimum load, resulting in abnormal temperature fluctuations and affecting the normal use of the equipment.

[0003] With the development of the times, the industry has new requirements for heat exchangers. Under the trend of energy conservation and environmental protection, industries urgently need heat exchangers that can improve heat exchange efficiency and reduce energy consumption. For example, in the power industry, efficient heat exchangers can help reduce cooling energy consumption and reduce greenhouse gas emissions. At the same time, the application scenarios of heat exchangers are constantly expanding, from traditional chemical, heating and ventilation fields to emerging fields such as new energy and electronic chip cooling. In these fields, electronic chip cooling requires heat exchangers to have high precision, miniaturization and high efficiency heat exchange capacity, while the new energy field requires heat exchangers to withstand high temperature, high pressure and highly corrosive media working environment, and to have high reliability and long service life. The multi-unit heat exchange area heat exchanger of the present application is designed to overcome the above-mentioned shortcomings of traditional heat exchangers and meet the new needs of industry development. Its unique structure design makes it have significant advantages in heat exchange efficiency, structural flexibility and application adaptability. SUMMARY
