Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand, the present invention will be further explained below with reference to the following embodiments and the accompanying drawings, but the following embodiments are only the preferred embodiments of the present invention, and not all embodiments are included. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention.

Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

Example 1

As shown in fig. 1-3, a crooked type metal finned tube, including support frame 4, the centre joint of support frame 4 has cooling tube 3, the left end welded fastening of cooling tube 3 has admission pipe 2, the right-hand member of cooling tube 3 has bent tube 1 through the bolt fastening, the below of cooling tube 3 is fixed with in the same direction as extending device 6 in the intermediate position department of support frame 4, the below of bent tube 1 has break away from pipe 5 in the right-hand member position department welded fastening of cooling tube 3, cooling tube 3 includes body 31, the fixed surface of body 31 has fin 32, body 31 includes pipe wall 311, the internal surface welded fastening of pipe wall 311 has barrier plate 312.

The fluid is introduced into the inlet pipe 2, the fluid enters the inlet pipe 2 and enters the wall of the inlet pipe 2 along the inlet pipe 2, the fluid moves in the pipe wall 311 to heat the pipe wall 311, the pipe wall 311 is heated to conduct heat to the radiating fins 32, the contact area between the radiating fins 32 and the air is large, the heat is conducted to the air, when the fluid moves in the pipe wall 311, the blocking plates block the fluid from moving, the direction of the fluid is changed along the blocking plates, the fluid flowing out of the radiating pipe 3 enters the bent pipe 1 and enters the separating pipe 5 along the bent pipe 1, the moving direction of the fluid can be blocked by the blocking plates, the fluid does not move in the pipe wall 311 along a straight line, the retention time of the hot fluid in the pipe wall 311 is effectively prolonged, the hot fluid can release more heat through the radiating pipe 3, and the temperature of the hot fluid is effectively reduced.
