Brief description of the drawings
The utility model is described in detail below by drawings and Examples.But the utility model is not limited to the present embodiment.
Fig. 1 is dimensional structure diagram of the present utility model.
Fig. 2 is inner surface of tube body expanded schematic diagram of the present utility model shown in Fig. 1.
Embodiment
A kind of efficient heat conducting tube of inner surface enhanced type, including body 1 and material on body 1 are along body 1
Radial direction extends and around body, helically state extension is integrally constituted with body 1 in the inner surface of body 1
Internal thread rib 2.It is preferred that, the quantity of the internal thread rib 2 is 8-75 bars, 10 ° -70 ° of spiral angle.
The groove 21 along the internal-rib bearing of trend interval shape distribution is provided with the top of internal thread rib 2, in the groove
21 bottom, which has, to intersect and interconnected channel structure 211.The helical angle of the internal thread rib 2 and the internal thread rib
The angle for the groove 21 that 2 top is distributed with interval shape is at an acute angle.The depth and width for two channel structures 211 intersected can phase
Deng or it is unequal, its angle is acute angle or right angle.
The utility model is because the top design of the internal thread rib 2 in heat transfer pipe internal surface is by groove 21 and groove 21
The reinforcing unit of the composition of channel structure 211 with intersection connected state of bottom, thus intraductal heat exchange table can be significantly increased
The area in face；Due to there is internal thread rib 2 in inside pipe wall, not only internal surface area is considerably increased compared to slippery inner surface while can
Change the mode of flow of fluid, making fluid, helically line flows along body direction, and fluid is in turbulent condition, strengthens heat convection
Effect.Fluid during fluid interchange fluid flow direction part, when fluid motion to the bottom of a certain laminated rib, fluid
Just have a flowing to climb and cross the process of internal thread rib, this process can be such that fluid fully contacts with tube wall, but simultaneously
The flow resistance of fluid can be increased, therefore, in order to reach suitable flow resistance, the internal thread rib 2 of the present utility model
Highly it is 0.1 ㎜ -1.0 ㎜.
Due to the effect of the structure of groove 21 on the internal thread rib 2, fluid can change side local flow direction, this mistake
Journey destroys the boundary layer of fluid, is conducive to fluid fully to be contacted with groove surfaces, increases local convection heat transfer effect.Flow part
Body, which climbs, will smoothly flow to after certain altitude and by groove, while increase Local Heat Transfer, the resistance of flow of fluid also by
Suitably reduce, if in the case that heat exchanger tube is large number of in set heat exchange device, for reducing unit water resistance, reducing water
Pump work consumption is highly beneficial.In the bottom of groove 21 there is the channel structure 211 intersected and be interconnected can also increase simultaneously
Part heat exchange surface area and the boundary layer for flowing local failure fluid, further increase tube fluid heat convection effect.For
Reach in rational circulation and the contact area and less flow resistance of groove, the present embodiment, the depth of groove 21 is
0.05 ㎜ -0.5 ㎜, width is 0.05 ㎜ -0.5 ㎜；The depth of channel structure 211 be 0.01 ㎜ -0.2 ㎜, width be 0.01 ㎜ -
0.2㎜。
The utility model be additionally included in body 1 outer surface have with body 1 it is integral and along the radius side of body 1
To the three-dimensional or the outer fin 3 of multidimensional for extending helically state, the height of the outer fin 3 is 0.5 ㎜ -1.5 ㎜, outer fin pitch
For 0.3 ㎜ -1 ㎜.
The three-dimensional or the outer fin 3 of multidimensional that the outer surface of body 1 has have larger benefit for lifting heat transfer outside a tube.
After condenser uses such heat-transfer pipe, the three-dimensional and multidimensional structure of outer fin 3 can be generally processed into as reinforcing condensation effect
Zigzag, these structures for reinforcing condensing heat-exchange it is highly beneficial, while can also increase the heat exchange surface area outside pipe, enhanced tube
Outer heat transfer effect.After evaporator uses such heat-transfer pipe, the three-dimensional and multidimensional structure of outer fin 3 can generally be processed into phase interaction
With interconnected opening structure, these structures exchange heat highly beneficial for reinforcing explosive evaporation.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New spirit and scope are defined.On the premise of the utility model design concept is not departed from, this area ordinary person couple
The all variations and modifications that the technical solution of the utility model is made, all should drop into protection domain of the present utility model, this reality
With new claimed technology contents, all record in detail in the claims.
