Combined type water-cooling heat dissipation machine shell and connecting piece and communicating pipe body thereof

The invention discloses a combined type water-cooling heat dissipation machine shell, a connecting piece of the combined type water-cooling heat dissipation machine shell and a communicating pipe body, and the combined type water-cooling heat dissipation machine shell is provided with a circulation path for circulation of cooling liquid and is provided with a support set and a plate body set. And the plate body group comprises a water cooling bar. Parts forming the support set can comprise a communicating pipe body, a structural strip body and a connecting piece. And a channel is formed in the communicating pipe body and is communicated with the water-cooling bar. And the communicating pipe body and the structural strip body form a framework of the shell. The connecting piece is used for connecting the communicating pipe body and the structural strip body. Therefore, a user can independently purchase each part and assemble and combine the purchased parts into the shell, and the flow path of the cooling liquid
