AI Technical Summary
The existing manifold lacks an effective vibration-damping structure when connected to the flat tube, which leads to wear at the end of the flat tube and easy damage during assembly, affecting sealing performance and service life.
A manifold with a flat tube groove was designed, with an internal flexible bushing and protective strip, combined with a protective cap and boss structure, to provide all-round protection and prevent damage to the flat tube during vibration and assembly.
It effectively reduces flat tube wear and assembly damage, improves connection reliability and service life, and ensures sealing and stability.

Abstract
Claims
1. A collector pipe having a flat pipe protection structure, comprising a collector pipe body (1) and a flat pipe (2), characterized in that: The main body (1) of the manifold is evenly provided with several flat tube grooves (3) for inserting flat tubes (2) from top to bottom. Protective caps (6) are threaded on both ends of the main body (1). Bosses (5) are provided on both the upper and lower sides of the flat tube grooves (3). A pipe mouth protection device (4) for protecting the end of the flat tube (2) after it is inserted is installed inside the flat tube grooves (3).
2. A collector pipe having a flat pipe protection structure according to claim 1, characterized in that: The inner wall of the protective cap (6) is provided with a threaded protrusion (61), and both ends of the manifold body (1) are provided with threaded grooves (11) that are compatible with the threaded protrusion (61).
3. The collector pipe with a flat pipe protection structure according to claim 1, characterized in that: The pipe opening protection device (4) includes a protective flange (41) that can be detachably installed on the outside of the flat pipe groove (3). The protective flange (41) is installed on the surface of the manifold body (1) by a nut.
4. The collector pipe with a flat pipe protection structure according to claim 1, characterized in that: The pipe end protection device (4) also includes a flexible bushing (42) that is fixedly pressed into the inner wall of the flat pipe groove (3), and a number of protective strips (43) are evenly arranged in the circumferential direction on the inner side of the flexible bushing (42).
5. A collector pipe with a flat pipe protection structure according to claim 4, characterized in that: The flexible bushing (42) is made of an elastic material, including one of silicone rubber, fluororubber, and wear-resistant engineering plastics; the inner hole shape of the flexible bushing (42) matches the outer contour of the flat tube (2), and an interference fit or clearance fit is adopted.
6. A manifold with a flat tube protection structure according to claim 1, characterized in that: The inlet edge of the flat tube groove (3) is chamfered to guide the flat tube (2) to be inserted smoothly. The inner edge of the flat tube groove (3) is turned inward with a small lip to increase the local rigidity of the tube opening.
