Description
Technical Field
The utility model relates to a heat exchange assembly field, concretely relates to novel energy-conserving heat transfer finned tube.
Background
The heat exchange tube is a key heat transfer element of the shell-and-tube heat exchanger, the performance of the heat exchanger is determined by the performance of the heat exchange tube, and various enhanced heat exchange tubes for enhancing heat transfer inside and outside the tube are developed in China in order to improve the heat transfer efficiency of the shell-and-tube heat exchanger. Although the types of the enhanced heat transfer pipes are various, certain surface structures are processed on the inner surface and the outer surface of a metal pipe to expand a heat transfer surface or improve a heat transfer coefficient, so that the heat transfer efficiency is improved, most commonly, the spiral finned pipes are spiral finned pipes, when the spiral finned pipes are used in a shell-and-tube heat exchanger, the spiral blades are easily deformed due to the fact that the spiral blades are washed for a long time due to high pressure of heat transfer liquid, the service life of the spiral blades is influenced, and when the spiral blade pipes are used for a long time, impurities can be accumulated in gaps of the spiral blades to influence the heat transfer efficiency.
SUMMERY OF THE UTILITY MODEL
In order to solve the existing problems, the utility model provides a novel energy-saving heat exchange finned tube.
The utility model discloses a realize through following technical scheme:
the utility model provides a novel energy-conserving heat transfer finned tube, includes the integrated into one piece's of parent tube and outer wall setting turn the fin, the even division in turn's the outside has a plurality of arc wall, is provided with a reinforced support bar between per two arc walls, reinforced support bar runs through to be fixed on turn the fin, the even division of the junction of turn the fin and parent tube has a plurality of arc through-flow bar hole.
Preferably, the distance between the bottom of the arc-shaped through-flow strip-shaped hole and the outer wall of the base pipe is 2mm-4 mm.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses an arc through-flow bar hole that sets up at the helical fin root, thereby erode the impurity that gathers between the helical fin, the impurity that has reduced helical fin gathers, the efficiency of heat transfer has been guaranteed, it has the arc wall to open in helical fin's the outside, it removes and erodees the area to reduce cold medium liquid, and the helical fin between two arc walls is fixed with a enhancement bracing piece that runs through it, can holistic improvement helical fin prevent the deformability, and the enhancement bracing piece can also compensate owing to open the arc wall and reduced cold and hot exchange area, guarantee the stability of heat transfer.

Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
as shown in fig. 1, fig. 2 and fig. 3, a novel energy-saving heat exchange finned tube comprises a base tube 1 and an integrally formed helical fin 2 arranged on the outer wall of the base tube, wherein a plurality of arc-shaped grooves 3 are uniformly formed in the outer side of the helical fin 2, a reinforcing support rod 5 is arranged between every two arc-shaped grooves 3, the reinforcing support rod 5 is fixed on the helical fin 2 in a penetrating manner, and a plurality of arc-shaped through-flow strip-shaped holes 4 are uniformly formed in the connection part of the helical fin 2 and the base tube 1.
The distance between the bottom of the arc-shaped through-flow strip-shaped hole 4 and the outer wall of the base pipe 1 is 2mm-4 mm.
The working principle is as follows: in use, the heat medium moves in the base pipe 1, the cold medium liquid flows from the outside of the base pipe 1 to exchange heat, a plurality of arc-shaped through-flow strip-shaped holes 4 are arranged at the position 2mm-4mm above the connection part of the base pipe 1 and the spiral fin 2, so that the cold medium liquid can flow from the arc-shaped through-flow strip-shaped holes 4, thereby flushing the impurities gathered between the spiral fins 2, reducing the gathering of the impurities of the spiral fins 2, ensuring the heat exchange efficiency, the arc grooves 3 are arranged on the outer sides of the spiral fins 2 to reduce the moving and washing area of the cold medium liquid, and the spiral fin 2 between the two arc grooves 3 is fixed with a reinforcing support rod 5 penetrating through the spiral fin 2, so that the deformation resistance of the spiral fin 2 can be integrally improved, and the reinforcing support rod 5 can also compensate the reduced cold-heat exchange area due to the arc-shaped groove 3, and ensure the stability of heat exchange.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
