Abstract

The utility model discloses an inner thread groove heat exchange pipe structure, which comprises a pipe body. Two groups of thread grooves are arranged in the pipe body, and thread directions of the two groups of the thread grooves are reverse. Thread pitches of the two groups of the thread grooves are unequal. Depths of the two groups of the thread grooves are different. The two groups of the thread grooves with reverse directions are arranged in the pipe body, thereby, fluid mediums which flow close to the inner wall of the pipe body are rotationally move along the thread grooves, when the fluid mediums flow to the connecting position of the two groups of the thread grooves, the fluid mediums which flow along two different thread grooves mutually impact, so that the fluid mediums close to the inner wall and the pipe body center in the pipe body produce a convection current, the fluid mediums in the pipe body are uniformly and alternately in contact with the inner wall of the pipe body for a heat exchange, and then the heat exchange efficiency of the heat exchange pipe is effectively increased, and simultaneously the scaling on the inner wall of the pipe body is effectively prevented.

Description

A kind of internal thread groove heat exchange tube structure
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 internal thread groove heat exchange tube structure.
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 internal thread groove heat exchange tube structure 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 internal thread groove heat exchange tube structure, include body, in described body, be provided with two groups of thread grooves, and two groups of spiral fluted hand of spirals are opposite.
As preferred version: the pitch of described two groups of thread grooves is unequal.
As preferred version: the degree of depth of described two groups of thread grooves is unequal.
Compared with prior art; The beneficial effect of the utility model is: owing in body, be provided with two groups of thread grooves that hand of spiral is opposite, like this, rotatablely move along thread groove near inboard wall of tube body flowing fluid medium; When fluid media (medium) flows junction to two groups of thread grooves; Impact each other along two different thread groove flowing fluid media, make that the fluid media (medium) near inwall and body center produces convection current in the body, the fluid media (medium) in the body evenly alternately with the inboard wall of tube body contact heat-exchanging; Thereby effectively strengthened the heat exchange efficiency of heat exchanger tube, also prevented the fouling of inboard wall of tube body simultaneously effectively.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1, body; 2, thread groove A; 3, thread groove B.
The specific embodiment
According to accompanying drawing the specific embodiment of the utility model is done a detailed explanation below.
Embodiment
According to shown in Figure 1, the described a kind of internal thread groove heat exchange tube structure of present embodiment includes body 1, in described body 1, is provided with two groups of thread grooves, be respectively the left-handed thread groove A2 and the thread groove B3 of dextrorotation, and two groups of spiral fluted hand of spirals is opposite.
The pitch of described two groups of thread grooves is unequal.The pitch of thread groove B is 1.3 times of thread groove A.
The degree of depth of described two groups of thread grooves is unequal.Like internal diameter of tube body 20mm, thickness 3mm, the thread groove A2 degree of depth is 1.5mm, the thread groove B3 degree of depth is 1mm.

Claims (3)
