Description

Technical Field

[0001] The invention relates to the technical field of heat exchangers, and in particular to a heat exchanger assembly machine. Background Art

[0002] With the continuous development of industrial technology, heat exchangers play a vital role in many fields. Heat exchangers are energy-saving devices that realize heat transfer between two or more fluids at different temperatures. Heat exchangers transfer heat through three methods: conduction, convection and radiation. The core is a heat exchange surface composed of a series of heat exchange tubes or heat exchange plates. High-temperature fluid and low-temperature fluid flow on both sides of the heat exchange surface respectively. The high-temperature fluid transfers heat to the heat exchange surface, and the heat exchange surface then transfers heat to the low-temperature fluid, thereby realizing heat exchange.

[0003] In the prior art, traditional heat exchanger assembly is usually carried out manually or semi-automatically. Workers need to accumulate fins and other parts one by one, and use manual tools to compress and flatten them, and finally bundle them. However, in the process of compacting the accumulated fins, it may not be convenient to flatten both sides of the fins in the width direction at the same time. As a result, after compacting, there may be gaps in the uneven parts, which will hinder the effective transfer of heat between the fins and reduce the heat exchange efficiency of the heat exchanger. Secondly, the unevenness of both sides of the fins will cause stress concentration during the compaction process. The stress concentrated parts are prone to deformation, cracking and other problems, reducing the structural strength of the heat exchanger. Summary of the invention
