Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger units, and specifically relates to a vertical modular heat exchanger unit. Background Technology

[0002] In the current industrial production and energy conversion fields, heat exchange units play an indispensable role in the heat transfer process. Their applications cover many key industries such as heating, refrigeration, chemical industry, and power. As one of the core equipment in these systems, the design optimization of heat exchange units is directly related to the overall system performance and economy.

[0003] Traditional heat exchanger units are generally designed with a horizontal layout, arranging key functional components such as heat exchange modules, circulation modules, and chemical dosing modules horizontally. This design approach ensures smooth connections between modules to a certain extent, facilitating daily maintenance and repair by operators, thereby improving system reliability and operating efficiency. However, with the continuous advancement of industrial technology and the accelerated pace of urbanization, the design of traditional horizontal heat exchanger units has gradually revealed a series of limitations, especially given the increasing scarcity and preciousness of land resources today.

[0004] The large footprint is one of the main challenges faced by horizontal heat exchanger units. Because the functional modules are laid out horizontally, the entire unit has a large projected area on the ground, which undoubtedly increases the difficulty of deployment and installation in industrial areas with limited land resources. The low space utilization not only limits the application potential of the heat exchanger unit in more scenarios but may also lead to additional infrastructure construction costs, such as expanding the plant or modifying the foundation, further increasing the overall project construction cost.
