DETAILED DESCRIPTION
[0015] As shown in the accompanying drawings, this embodiment provides a submersible motor external circulation radiator with a tubular structure, including a tubular radiator body 1, and a delivery pipe 2 passing through the middle of the radiator body 1.
[0016] A boss 6 is provided at the top of the radiator body 1 , and the boss 6 is used to cooperate with the wellhead 7 to fix the radiator body.
[0017] The radiator body 1 is a hollow structure. A water inlet 8 is provided at the bottom end of the radiator body 1, and a water outlet 5 is provided at the top of the radiator body 1. A water inlet pipe 9 and a water outlet pipe 4 are connected to the radiator body 1. The water inlet pipe 9 is connected to the water inlet 8, and the water outlet pipe 4 is connected to the water outlet 5. The water inlet pipe 9 and the water outlet pipe 4 are both connected to the hollow interior of the radiator body 1.
[0018] A groove 3 is provided on the central inner wall of the radiator body 1 from top to bottom, and the water outlet pipe 4 is embedded in the groove 3 and confined on the central inner wall of the radiator body 1 .
