Abstract

The utility model discloses an aluminum alloy pipe comprising a pipe body, wherein the pipe body is provided with an inner pipe wall and an outer pipe wall, the inner pipe wall forms a pipe cavity by surrounding, and a plurality of cavities are arranged between the inner pipe wall and the outer pipe wall on the pipe body. The pipe cavity is cylindric, and the cavities are uniformly distributed by taking the center of circle of the pipe cavity as a center. A plurality of grooves are arranged on the outer pipe wall. By adopting the aluminum alloy pipe, as the plurality of cavities are arranged on the pipe body, the weight of the entire pipe body is reduced, and materials are saved; simultaneously, cooling liquid can circulate in the cavities, thus improving the effect of heat dissipation of the aluminum alloy pipe; as the plurality of grooves are arranged on the outer pipe wall, the area of heat dissipation of the outer pipe wall is enlarged, thereby further improving the effect of heat dissipation; and due to the existence of the grooves, materials for the pipe body are further saved.

Description

A kind of Al-alloy pipe

Technical field

The utility model relates to a kind of Al-alloy pipe, particularly relates to a kind of Al-alloy pipe that is used to transmit high temperature, high-pressure liquid.

Background technique

Some occasions in chemical industry or other industry, need fluid with some high temperature of pipeline transmission, high pressure, these fluids also have certain corrosivity sometimes, common way is to transmit with the Al-alloy pipe that tube wall is thickeied, because in order to make the used Al-alloy pipe can be high pressure resistant and tube wall is thickeied, cause the cost of material of whole transmission pipeline to increase greatly, simultaneously, the heat dispersion of Al-alloy pipe is reduced.

Summary of the invention

For overcoming above-mentioned defective, the utility model aims to provide and a kind ofly can at utmost reduce the transmission pipeline cost, a kind of Al-alloy pipe that can effectively dispel the heat again simultaneously.

The technological scheme that adopts is: a kind of Al-alloy pipe, comprise pipe shaft, and described pipe shaft has inner tube wall and pipe outer wall, and described inner tube wall surrounds tube chamber, is provided with several cavitys on the described pipe shaft between inner tube wall and pipe outer wall.

Described tube chamber is cylindric, and described cavity is that the center evenly distributes with the center of circle of tube chamber.

Described pipe outer wall is provided with several grooves.

Adopted Al-alloy pipe of the present utility model,, the weight of whole pipe shaft has been descended because it is provided with several cavitys on pipe shaft, also just saved material, simultaneously, all right circulating cooling liquid in the cavity, the radiating effect of reinforcement Al-alloy pipe, be provided with several grooves at the pipe outer wall again simultaneously, increase the heat diffusion area of pipe outer wall, further increased radiating effect, simultaneously, because groove has existence, has also further saved the material of pipe shaft.

Description of drawings

Fig. 1 is a sectional structure chart of the present utility model;

Fig. 2 is an a kind of embodiment's of the present utility model sectional structure chart.

Among the figure: the 1-pipe shaft, the 2-tube chamber, the 3-cavity, the 4-groove, the 11-inner tube wall, 12-manages outer wall.

Embodiment

As shown in Figure 1, the utility model discloses a kind of Al-alloy pipe, comprise pipe shaft 1, described pipe shaft 1 has inner tube wall 11 and pipe outer wall 12, and described inner tube wall 11 surrounds tube chamber (2), is provided with several cavitys 3 on the described pipe shaft 1 between inner tube wall 11 and pipe outer wall 12.Described tube chamber 2 is cylindric, and described cavity 3 is that the center evenly distributes with the center of circle of tube chamber 2.

The cross section of described pipe outer wall 12 is a regular polygon, what adopt usually is regular hexagon, can certainly adopt other regular polygon, as octagon etc., cavity 3 can adopt ellipse or runway shape or circle etc., for more effective saving material and processability, usually adopt runway shape, the setting of the quantity of cavity 3 and size should be able to be under the prerequisite that guarantees pipe shaft 1 intensity, cavity 3 should be parallel with tube chamber 2 and be run through whole pipe shaft 1, the yard of enhance heat need be carried out at some, cooling liquid can be passed through in the cavity 3.

For further increasing the radiating effect of pipe shaft 1, described pipe outer wall 12 is provided with several grooves 4.Groove 4 shapes or semicircle or triangle etc., described groove 4 is parallel with pipe outer wall 12 and run through whole pipe shaft 1.

As shown in Figure 2, be another kind of embodiment of the present utility model, the cross section of pipe outer wall 12 is circular, cavity 3 can adopt ellipse or runway shape or circle etc., for more effective saving material and processability, adopts runway shape usually, the setting of the quantity of cavity 3 and size should be able to be under the prerequisite that guarantees pipe shaft 1 intensity, cavity 3 should be parallel with tube chamber 2 and be run through whole pipe shaft 1, need carry out the yard of enhance heat at some, can pass through cooling liquid in the cavity 3.

Al-alloy pipe of the present utility model can adopt heat extrusion compacting.

Adopted Al-alloy pipe of the present utility model,, the weight of whole pipe shaft 1 has been descended because it is provided with several cavitys 3 on pipe shaft 1, also just saved material, simultaneously, all right circulating cooling liquid in the cavity 3, the radiating effect of reinforcement Al-alloy pipe, be provided with several grooves 4 at pipe outer wall 12 again simultaneously, increase the heat diffusion area of pipe outer wall 12, further increased radiating effect, simultaneously, because groove 4 has existence, has also further saved the material of pipe shaft.

Claims
