The outer fin of multidimensional also greatly improves heat transfer outside a tube effect.
Brief description of the drawings
Below by drawings and Examples in detail the present invention is described in detail.But the invention is not restricted to the present embodiment.
Fig. 1 is dimensional structure diagram of the invention.
Fig. 2 is inner surface of tube body expanded schematic diagram of the invention shown in Fig. 1.
Specific embodiment
A kind of efficient heat conducting tube of inner surface enhanced type, including body 1 and by the material on body 1 along body 1
Radial direction extend and body 1 inner surface around body helically being integrally constituted with body 1 of extending of state
Internal thread rib 2.Preferably, the quantity of the internal thread rib 2 is 8-75 bars, 10 ° -70 ° of spiral angle.
The groove 21 being distributed along internal-rib bearing of trend interval shape is provided with the top of internal thread rib 2, in the groove
21 bottom has the channel structure 211 intersected and be interconnected.The helical angle of the internal thread rib 2 and the internal thread rib
2 top is at an acute angle to be spaced the angle of the groove 21 of shape distribution.Two depth and width of channel structure 211 intersected can phase
Deng or it is unequal, its angle is acute angle or right angle.
The present invention is because the top design of the internal thread rib 2 in heat transfer pipe internal surface is by groove 21 and the bottom of groove 21
The reinforcing unit with the composition of channel structure 211 for intersecting connected state, thus intraductal heat exchange surface can be significantly increased
Area；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, helically line flows along body direction to make fluid, and fluid is in turbulent condition, enhancing heat convection effect
Really., in the part of fluid flow direction during fluid interchange, when fluid motion to the bottom of a certain laminated rib, fluid is just for fluid
Have a flowing to climb and cross the process of internal thread rib, this process can be such that fluid is fully contacted with tube wall, but also can simultaneously
Increase the flow resistance of fluid, therefore, in order to reach suitable flow resistance, the height of the internal thread rib 2 of the invention 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 to be fully contacted with groove surfaces, increases local convection heat transfer effect.Flow part
Body climbs and will smoothly flow to after certain altitude and by groove, while increasing 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 the set heat exchange device, for reducing unit water resistance, reducing water
Pump work consumption is highly beneficial.Can also increase with the channel structure 211 intersected and be interconnected in the bottom of the groove 21 simultaneously
Part heat exchange surface area simultaneously flows the boundary layer of local failure fluid, further increases tube fluid heat convection effect.For
The contact area and less flow resistance of rational circulation and groove are reached, in 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㎜。
Present invention additionally comprises in the outer surface of body 1 there is radial direction integral with body 1 and along body 1 to prolong
The three-dimensional or the outer fin 3 of multidimensional of helically state are stretched, the height of the outer fin 3 is 0.5 ㎜ -1.5 ㎜, and outer fin pitch is
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 the preferred embodiment of the present invention is described, not to structure of the invention
Think and scope is defined.On the premise of design concept of the present invention is not departed from, this area ordinary person is to technology of the invention
The all variations and modifications that scheme is made, all should drop into protection scope of the present invention, claimed technology contents of the invention,
All record in detail in the claims.
