Abstract
The utility model discloses a high-efficiency heat exchange tube. The heat exchange tube comprises a heat exchange tube body, wherein equidistant annular grooves are tapped on the inner wall of the heat exchange tube body; the depth of the annular grooves is 0.5-1 mm, and the space of the annular grooves is 5-30 mm; and the two ends of the heat exchange tube are provided with non-groove polished tube sections. The heat exchange tube has a simple structure, large heat transfer area and high heat exchange efficiency.
Description
Technical field
The utility model relates to a kind of heat exchange element, especially a kind of heat exchanger tube of shell-and-tube heat exchanger.
Background technology
Shell-and-tube heat exchanger belongs to a kind of in the dividing wall type heat exchanger, and its particular structure makes it can bear higher temperature and pressure, and its application is wideer than plate type heat exchanger.But its structure more complicated, floor space is big, and is relatively heavier; The processing and manufacturing cost is high, and, the common smooth inner wall pipe of the many employings of the heat exchanger tube of shell-and-tube heat exchanger of the prior art; Therefore, the effective heat exchange area of this heat exchanger is less, and fluid is difficult for forming turbulent flow in heat exchanger tube; Cause the heat exchange efficiency of this shell-and-tube heat exchanger lower, its application in market is limited to.
The utility model content
The technical problem that utility model will solve is: a kind of efficient heat-exchanging pipe is provided, and this heat exchange tube structure is simple, heat transfer area is big, heat exchange efficiency is high.
The technical scheme that the technical solution problem is taked: a kind of efficient heat-exchanging pipe, comprise heat exchange tube body, on the heat exchange tube body inwall, attack the annular groove that is carved with equidistance, the degree of depth of annular groove is 0.5-1mm, spacing is 5-30mm.
Improvement as the utility model: be provided with unnotched light pipe section at the two ends of heat exchanger tube.
Beneficial effect: the efficient heat-exchanging pipe of the utility model comprises heat exchange tube body owing to having adopted, and on the heat exchange tube body inwall, attacks the annular groove that is carved with equidistance, and the degree of depth of annular groove is 0.5-1mm; Spacing is the technical scheme of 5-30mm; Increase the contact area of heat exchanger tube and tube fluid effectively, under the situation of length that does not change heat exchanger tube and internal diameter, increased the heat transfer area of heat exchanger tube; And increased the roughness of heat exchanger tube inwall; Make the medium in the pipe under the operating mode of low flow velocity, also can form turbulent flow, therefore, the heat exchange efficiency of the shell-and-tube heat exchanger that the heat exchanger tube of employing the utility model is processed is higher; Owing to adopted the technical characterictic that is provided with unnotched light pipe section at the two ends of heat exchanger tube, can prevent effectively that heat exchanger tube is damaged in the welding position with tube sheet in manufacturing process.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the axial section of the efficient heat-exchanging pipe of the utility model.
The specific embodiment
As shown in Figure 1, the efficient heat-exchanging pipe of the utility model comprises heat exchange tube body 2, on the heat exchange tube body inwall, attacks the annular groove 3 that is carved with equidistance, and the degree of depth of annular groove is 0.5-1mm, and spacing is 5-30mm, is provided with unnotched light pipe section 1 at the two ends of heat exchanger tube.
Claims (2)
1. an efficient heat-exchanging pipe comprises heat exchange tube body, it is characterized in that: on the heat exchange tube body inwall, attack the annular groove that is carved with equidistance, the degree of depth of annular groove is 0.5-1mm, and spacing is 5-30mm.
2. efficient heat-exchanging pipe according to claim 1 is characterized in that: be provided with unnotched light pipe section at the two ends of heat exchanger tube.
