Description

Technical Field

[0002] Internally threaded copper tubes, also known as non-smooth tubes, refer to internally threaded TP2 copper tubes with a smooth outer surface and a certain number of regular threads on the inner surface, which are filled with heat exchange medium. Due to the increase in the inner surface area of ​​the internally threaded copper tube, its thermal conductivity is 20 to 30 percent higher than that of the smooth tube. With the world's energy shortage and the implementation of the domestic energy efficiency air conditioning access system, internally threaded copper tubes will be widely used in the air conditioning and refrigeration industry;

[0003] The existing copper pipes are partially connected by welding. In this case, after long-term use, if one or more sections of the copper pipes are damaged, the damaged parts cannot be replaced. In this case, internal threaded copper pipes are used for connection;

[0004] Moreover, the internal teeth of the existing internally threaded copper tube are complete internal teeth. There are fewer bubble nucleation points during the evaporation of the medium, and the heat exchange effect cannot be maximized. At the same time, the structure of the internal teeth will be destroyed during the tube expansion process. Therefore, it does not meet the existing needs. We have proposed a high-density tooth internally threaded copper tube structure. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] In a basic embodiment of the present application, a high-density tooth internal thread copper tube structure is disclosed, including a connecting seat 1, a copper tube A2 and a copper tube B3. The connecting seat 1 is a cylindrical structure with openings at both ends, and an internal thread 102 is provided in a connecting hole 103 of the connecting seat 1; the two ends of the copper tube A2 and the copper tube B3 are provided with external threads B4 that are compatible with the internal threads 102, and the copper tube A2 and the copper tube B3 are connected to the connecting hole 103 of the connecting seat 1 through the external threads B4 and the internal threads 102; the copper tube A2 and the copper tube B3 are both provided with combined teeth 5 inside, and the combined teeth 5 include a plurality of tooth blocks with different structures and / or sizes.

[0028] In the present application, there is no limit to the number of the connection socket 1 and the copper tubes A2 and B3. One connection socket can connect two copper tubes, and three copper tubes can be connected through two connection sockets.

[0029] When connecting, screw the external thread B4 at the end of the copper tube into the internal thread 102 of the connecting seat 1 to realize the installation connection between the copper tube and the connecting seat 1. If one of the copper tubes is damaged during use, the damaged copper tube can be easily removed. The threaded connection is not only easy to disassemble, but also can ensure the sealing effect after connection. In order to further ensure the sealing of the copper tube after connection, a sealing ring can be designed at the end of the copper tube. When the copper tube and the connecting seat 1 are connected, the end of the connecting seat squeezes the sealing ring to further ensure the sealing performance between the copper tube and the connecting seat.

[0030] The present application also designs a combination tooth 5 inside the copper tube A2 and the copper tube B3, and the combination tooth 5 includes a plurality of tooth blocks with different structures and / or sizes. By designing tooth blocks with different structures and / or sizes, it is more conducive to gas-liquid mixing and provides more nucleation points, thereby improving heat exchange efficiency.
