Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and more specifically, to an assembly and positioning device for an external heat exchanger tube bundle. Background Technology

[0002] An external heat exchanger, also known as an external heat exchanger, is a key piece of equipment widely used in industrial boilers, chemical reactors, and heat recovery systems. Its basic working principle is to transfer heat energy within the system to the medium that needs to be heated through heat exchange tube bundles, thereby improving overall thermal efficiency. In actual operation, for ease of maintenance and repair, external heat exchangers are usually designed with a detachable structure, typically consisting of an outer shell, tube sheet, and tube bundle. The tube bundle is the core component of the external heat exchanger, consisting of several heat exchange tubes. These tubes are usually circular or have other cross-sections suitable for fluid flow. Internal and external fluids transfer heat through heat exchange, and the tube bundle separates the two fluids to ensure heat exchange between them.
