Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1-5, the pipe and flat wall connection structure of the present invention includes a pipe 1, a flat wall 2 with holes 3, and a closed side wall 4, wherein the pipe 1 is inserted into the hole 3, the side wall 4 is welded and fixed on the flat wall 2 in a manner of surrounding the pipe 1, a groove 7 is formed between an outer wall surface 5 of the pipe 1 and an inner wall surface 6 of the side wall 4, and a sealant 8 is filled in the groove 7.

The tube 1 is inserted into the bore 3, the tube 1 being coaxial or substantially coaxial with the bore 3. The pipe 1 is generally a circular pipe 1, and in some cases, the pipe 1 may be a square pipe or a pipe having a cross section of another shape as necessary. The shape of the hole 3 matches the cross-section of the tube 1, for example for a circular tube 1, the hole 3 may be a circular hole; for a square tube 1, the hole 3 may be a square hole 3.

A closed side wall 4 surrounds the hole 3 and is welded at one end to the flat wall 2, the side wall 4 extending axially away from the flat wall 2. For example, the sidewall 4 may be a round short tube with a round cross section or a square short tube with a square cross section. Thus, there are various combinations of cross-sectional shapes of the tube 1 and the side wall 4, such as circular cross-sections of the tube 1 and the side wall 4, or square cross-sections of the tube 1 and the side wall 4, or circular cross-sections of the tube 1 and square cross-sections of the side wall 4.

Referring to fig. 3-4, the side wall 4 surrounds the tube 1, a groove 7 is formed between the inner wall surface 6 of the side wall 4 and the outer wall surface 5 of the tube 1, and the flat wall 2 serves as the bottom of the groove 7. When the pipe 1 is a circular pipe and the side wall 4 is circular, the groove 7 is a circular groove.

The connecting structure of the embodiment adds the side wall 4 on the side surface of the flat wall 2, so that the groove 7 is formed around the pipe 1, the side wall 4 extends along the axial direction, the sealant 8 is filled in the groove 7, the bonding area of the sealant 8 is increased, on one hand, the sealing performance is enhanced, on the other hand, the connecting strength is increased, and the sealant 8 is not easy to fall off.

In some embodiments, a single side of the flat wall 2 is provided with a side wall 4. The side wall 4 is arranged on one side of the flat wall 2 and is sealed by glue, so that the good sealing performance and connection strength of the connection structure can be ensured.

In some embodiments, both sides of the flat wall 2 are provided with side walls 4. This embodiment can further enhance the sealing property and the connection strength of the connection structure.

In some embodiments, the tube 1 and the flat wall 2 are of different materials and the side wall 4 and the flat wall 2 are of the same material. The utility model discloses a connection structure has shown the superiority in the pipe 1 and the flat wall 2 of xenogenesis material are connected. Taking a tube heat exchanger as an example, generally speaking, the tube 1 and the flat wall 2 are made of different materials, for example, the tube 1 is made of a material with high thermal conductivity, and the flat wall 2 may be made of a structural material with high strength, so that the tube 1 and the flat wall 2 are difficult to be fixed and sealed by welding, are directly glued, and are easy to fall off and leak gas and liquid. The utility model discloses an among the connection structure, lateral wall 4 is the same kind of material with flat wall 2, can weld sealed on flat wall 2, is connected and sealed through sealed glue 8 between pipe 1 and the lateral wall 4, owing to increased the bonding area, consequently no matter 1 is leakproofness or joint strength, has all increased substantially.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
