Abstract
The utility model relates to an inner-spiral outer-fin copper heat exchange tube, which comprises a copper tube body (1), and is characterized in that: the outer wall of the copper tube body (1) is provided with spiral fins (2); and the inner wall of the copper tube body (1) is provided with spiral grooves (3). The inner-spiral outer-fin copper heat exchange tube increases the inner and outer heat transfer areas of the tube, and disturbs a laminar medium flowing on the inner and outer walls of the tube through the spiral grooves and the fins to make the medium generate turbulence at a low flow rate so as to strengthen the heat exchange inside and outside the tube and greatly improve the heat transfer.
Description
(1) technical field
The utility model relates to a kind of heat exchanger tube, is specifically related to the outer fin copper heat exchanger tube of a kind of inside spin.
(2) background technology
Along with improving constantly of industry technologies such as refrigeration, metallurgy, machinery, boiler manufacturing, the requirement of heat exchanging device also improves accordingly.The performance of heat exchanger depends on the performance of heat exchanger tube to a great extent.At present, traditional mode is to adopt the bronzing pipe of good heat conductivity as heat exchanger tube, in order to strengthen its heat exchange efficiency, all is the fin that is rolled into all size height at circular tube exterior generally, thereby carries out heat conduction reinforced to this kind tube exterior.But except the outside need augmentation of heat transfer, the internal heat transfer ability is also very poor for some medium, and this in the past situation can only lean on increase equipment to solve merely.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of body inside spin that inside and outside heat exchange is all strengthened outer fin copper heat exchanger tube.
The purpose of this utility model is achieved in that the outer fin copper heat exchanger tube of a kind of inside spin, and it comprises the copper pipe body, it is characterized in that: described copper pipe body outside wall surface is provided with helical fin, and described copper pipe inner body wall face is provided with spiral grooves.
Compared with prior art, the beneficial effects of the utility model are:
The outer fin copper heat exchanger tube of the utility model inside spin, increased the inside and outside heat transfer area of pipe, utilize spiral groove and fin that the laminar flow medium that the pipe inside and outside wall flows is carried out disturbance simultaneously, make medium under low flow velocity, just can produce turbulent condition, the inside and outside heat exchange of body is all strengthened, and heat transfer property significantly improves.
(4) description of drawings
Fig. 1 is the structural representation of the outer fin copper heat exchanger tube of the utility model inside spin.
Wherein:
Copper pipe body 1, helical fin 2, spiral grooves 3.
(5) specific embodiment
Referring to Fig. 1, the outer fin copper heat exchanger tube of a kind of inside spin that the utility model relates to, it is to utilize rolling cutter to roll out helical fin 2 in copper pipe body 1 outside wall surface, just processes spiral grooves 3 at copper pipe body 1 internal face again.
Claims (1)
1. the outer fin copper heat exchanger tube of an inside spin, it comprises copper pipe body (1), it is characterized in that: described copper pipe body (1) outside wall surface is provided with helical fin (2), and described copper pipe body (1) internal face is provided with spiral grooves (3).
