Abstract
The utility model discloses an internal thread heat exchange pipe. The internal thread heat exchange pipe comprises a heat exchange pipe body, threads are tapped on the inner wall of the heat exchange pipe body, and the threads are cross threads. Through the internal thread heat exchange pipe, the contact area of the heat exchange pipe and fluid in the pipe is effectively enlarged, and the heat transfer area of the heat exchange pipe is enlarged under the condition that the length and the inside diameter of the heat exchange pipe are not changed; the inner wall of the cross thread heat exchange pipe is rough, so that turbulence is easy to form under the working condition of low Reynolds number; and the internal thread heat exchange pipe has the advantages of 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 is claimed tubular heat exchanger again, belongs to a kind of in the dividing wall type heat exchanger, and this heat exchanger structure is simpler, and reliable can be used under high temperature, high pressure, is to use the widest heat exchanger at present.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 internal thread heat exchanger tube is provided, and this internal thread 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 internal thread heat exchanger tube, comprise heat exchange tube body, on the heat exchange tube body inwall, attacked screw thread, said screw thread is for intersecting screw thread.
Improvement as the utility model: said screw thread is a bull intersection screw thread.
Further improvement as the utility model: be provided with threadless light pipe section at the two ends of internal thread heat exchanger tube.
Further improvement again as the utility model: the degree of depth of screw thread is 0.5-1mm.
Best-of-breed technology scheme as the utility model: multiple-threaded pitch is 2-15mm.
Beneficial effect: the internal thread heat exchanger tube of the utility model, comprise heat exchange tube body owing to adopted, on the heat exchange tube body inwall, attacked screw thread; Said screw thread is the technical scheme of intersection screw thread, has increased 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 the inner wall coarse of this intersection screw thread heat exchanger tube forms turbulent flow easily under the operating mode of low reynolds number; Therefore, adopt the heat exchange efficiency of the shell-and-tube heat exchanger that the heat exchanger tube of the utility model processes higher; Because having adopted said screw thread is that bull is intersected the technical characterictic of screw thread, make that the heat-transfer effect of internal thread heat exchanger tube of the utility model is better, and the resistance of heat exchanger tube is also less; Owing to adopted the technical characterictic that is provided with threadless light pipe section at the two ends of internal thread heat exchanger tube, can prevent effectively that heat exchanger tube is damaged in the welding position with tube sheet in manufacturing process; Owing to reasonably define the degree of depth and the multiple thread pitch of intersection screw thread, make the heat exchange effect of the internal thread heat exchanger tube of the utility model reach best.
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 internal structure sketch map of the internal thread heat exchanger tube of the utility model.
The specific embodiment
As shown in Figure 1, the internal thread heat exchanger tube of the utility model comprises heat exchange tube body 3; On the heat exchange tube body inwall, attacked screw thread 2, be provided with threadless light pipe section 1 at the two ends of internal thread heat exchanger tube, said screw thread is for intersecting screw thread; In order to obtain better heat exchange effect; The screw thread of attacking system is a bull intersection screw thread, and the degree of depth of screw thread is 0.5-1mm, and multiple-threaded pitch is 2-15mm.
Claims (5)
1. an internal thread heat exchanger tube comprises heat exchange tube body, it is characterized in that: on the heat exchange tube body inwall, attacked screw thread, said screw thread is for intersecting screw thread.
2. internal thread heat exchanger tube according to claim 1 is characterized in that: said screw thread is a bull intersection screw thread.
