Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to an installation structure for a heat exchanger core. Background Technology

[0002] The core of a flat-tube finned heat exchanger is formed by arranging several equally spaced metal flat tubes, with fins inserted between every two adjacent tubes. For the fins to be inserted into the tubes, the flat tubes need to be positioned first. Common methods for positioning and fixing the flat tubes involve using clamps on both sides, but this method makes it difficult to maintain a consistent spacing between the tubes. Since the fins are bonded to the flat tubes with adhesive, excessive spacing can lead to insecure connections. Alternatively, modules with equally spaced grooves can be used, placing the flat tubes within the grooves. However, these modules lack corresponding fixing devices, and the flat tubes may move along the grooves. Therefore, the idea is to combine the equally spaced module with the clamps on both sides of the flat tubes into a single unit, resulting in a heat exchanger core installation structure that integrates positioning and fixing.
