Abstract
The utility model discloses a heat exchange pipe with spiral grooves, which belongs to the technical field of parts of general heat exchange or heat transmission equipment. The heat exchange pipe with the spiral grooves comprises a pipe body. An internal spiral groove is arranged on an inner wall of the pipe body and an external spiral groove is arranged on an outer wall of the pipe body. The pitch of the internal spiral groove is equal to that of the external spiral groove, and the internal spiral groove does not overlap with the external spiral groove to prevent insufficient mechanical strength caused by an over-small local thickness of the pipe body. Depths of the internal spiral groove and the external spiral groove are smaller than half of a wall thickness of the pipe body. Due to the fact that the spiral grooves are arranged on both the inner wall and the outer wall, a contact area between a heat exchange medium and the pipe body is enlarged; furthermore, due to disturbance caused by the internal spiral groove inside the pipe body to a heat exchange medium, heat exchange efficiency of the heat exchange pipe is improved and scale formation on the inner wall of the pipe body is prevented simultaneously.
Description
Technical field
The utility model belongs to the parts technical field of interchangeable heat exchange or heat-transfer equipment, relates in particular to a kind of helical groove heat exchange pipe.
Background technology
Development along with industries such as refrigeration plant, boiler and metallurgy; Correspondingly exchange the heat transfer efficiency of heat pipe and also more and more pay attention to, the heat exchanger tube of prior art has light pipe and finned tube etc., and finned tube is through increasing fin to increase the contact area of heat exchanger tube and heat transferring medium in heat exchange tube or outside the pipe; Improved the heat exchange efficiency of heat exchanger tube to a certain extent; But fin generally is connected on the heat exchanger tube through welding or rolling mode, and production and processing comparatively bothers, and cost is higher.
Summary of the invention
The purpose of the utility model is: it is high to propose a kind of heat exchange efficiency, and helical groove heat exchange pipe easy to process, to overcome the deficiency that prior art exists.
For realizing the purpose of the utility model, adopt following technical scheme to be achieved: a kind of helical groove heat exchange pipe, include body, be provided with inner spiral groove at the inwall of said body, be provided with external spiral groove at said tube wall.
As preferred version: the pitch of described inner spiral groove and external spiral groove equates, and inner spiral groove and external spiral groove non-overlapping, crosses thin and causes the mechanical strength deficiency with the local thickness that prevents body.
As preferred version: the degree of depth of described inner spiral groove and external spiral groove is half the less than the body wall thickness all.
Compared with prior art; The beneficial effect of the utility model is: owing to all be provided with helicla flute at the inside and outside wall of body; Increased the contact area of heat transferring medium and body; And the inner spiral groove heat exchanging medium in the body produces disturbance, has improved the heat exchange efficiency of heat exchanger tube, has also prevented the fouling of inboard wall of tube body simultaneously.

The specific embodiment
According to accompanying drawing the specific embodiment of the utility model is done a detailed explanation below.
Embodiment
According to illustrated in figures 1 and 2, the described helical groove heat exchange pipe of present embodiment includes body 1, is provided with inner spiral groove 3 at the inwall of said body 1, is provided with external spiral groove 2 at said body 1 outer wall.
The pitch of described inner spiral groove 3 and external spiral groove 2 equates, and inner spiral groove 3 and external spiral groove 2 non-overlappings.1/2 to 1/3 of desirable body 1 internal diameter of pitch of described inner spiral groove 3 and external spiral groove 2.
The degree of depth of described inner spiral groove 3 and external spiral groove 2 is half the less than body 1 wall thickness all.Such as, 1/3 of desirable body 1 wall thickness.
