Abstract
The utility model discloses an inside spin side -finned heat transfer copper pipe belongs to the heat pipe technique field of trading, including copper pipe main part, the inner wall of copper pipe main part is equipped with spiral ridge no. 1 and spiral groove no. 1, the outer wall of copper pipe main part is equipped with spiral ridge no. 2 and spiral groove no. 2, spiral ridge no. 1 and spiral groove are two corresponding, spiral ridge no. 2 and spiral groove are one corresponding, be equipped with the helical fin on the outer wall of copper pipe main part, helical fin highly all the same. The utility model discloses increased the hot exchange area of copper pipe, utilized the laminar flow medium that spiral ridge no. 1 and spiral groove a pair of inside pipe wall flow to carry out the disturbance simultaneously, made the medium just can produce turbulent state down at the low velocity of flow, improved heat transfer efficiency, suitable promotelow carbon economic, energy -concerving and environment -protective requirement.
Description
Technical field
This utility model discloses a kind of inner-spiral outer-fin heat transmission copper pipe, belongs to heat exchanger tube technical field.
Background technology
With the continuous improvement of the industry technology such as refrigeration, metallurgy, machinery, boiler manfacturing, the requirement of heat exchanger is also corresponding
Raising.The performance of heat exchanger is heavily dependent on the performance of heat exchanger tube.At present, traditional mode is to adopt heat conductivility
Good copper pipe, in order to strengthen its heat exchange efficiency, is typically all rolled into all size high as heat exchanger tube outside circular round pipes
The fin of degree, it is heat conduction reinforced so as to carry out to this kind of tube exterior, but for some media are except outside need augmentation of heat transfer
Outward, internal heat transfer ability is poor.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide for a kind of inner-spiral outer-fin heat transfer
Copper pipe, to solve the problems, such as above-mentioned background technology in propose.
For achieving the above object, this utility model provides following technical scheme to realize：
A kind of inner-spiral outer-fin heat transmission copper pipe, including copper pipe main body, is characterized in that：The inwall of the copper pipe main body is provided with
Spiral salient one and helical groove one, the outer wall of the copper pipe main body is provided with spiral salient two and helical groove two, the spiral
Projection one and helical groove two are corresponding, and the spiral salient two and helical groove one are corresponding, the outer wall of the copper pipe main body
Helical fin is provided with, the height of the helical fin is all identical.
As preferred：The width of the helical groove one is 1.5～2 times of spiral salient one.
As preferred：The spiral salient one, helical groove one and spiral salient two, helical groove two and helical fin
Hand of spiral all same.
As preferred：The spiral angle of the spiral salient one is 30～60 degree.
As preferred：The helical fin is formed by knurling tool rolling.
The beneficial effects of the utility model：
1st, the setting of helical fin, spiral salient two and helical groove two increased the heat exchange area of copper pipe, also cause
Condensate is gathered at one and drips, and reduces pollution.2nd, using the layer of a pair of inside pipe wall flowings of spiral salient one and helical groove
Flow medium is disturbed, and makes laminar flow medium just to produce turbulent condition at low flow rates, the time of staying of prolonged layer flow medium,
Heat transfer efficiency is improve, is adapted to low-carbon economy, the requirement of energy-conserving and environment-protective.

Specific embodiment
A kind of inner-spiral outer-fin heat transmission copper pipe of this utility model is described further with reference to Fig. 1.
A kind of inner-spiral outer-fin heat transmission copper pipe, including copper pipe main body 1, is characterized in that：The inwall of the copper pipe main body 1 sets
The outer wall for having spiral salient 1 and helical groove 1, the copper pipe main body is provided with spiral salient 24 and helical groove 25, institute
State spiral salient 1 and helical groove 25 is corresponding, the spiral salient 24 and helical groove 1 are corresponding, the copper pipe
The outer wall of main body 1 is provided with helical fin 6, and the height of the helical fin 6 is all identical.
By arranging helical fin 6, spiral salient 24 and helical groove 25, the heat exchange area of copper pipe is increased,
So that condensate is gathered at one dripping, pollution is reduced.
Disturb by using the laminar flow medium of one 3 pairs of inside pipe wall flowings of spiral salient 1 and helical groove, make medium
Turbulent condition can be just produced at low flow rates, the time of staying of prolonged layer flow medium, heat transfer efficiency is improve, and be adapted to low-carbon (LC) Jing
Ji, the requirement of energy-conserving and environment-protective.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, some improvement under the premise of without departing from this utility model principle and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
