Abstract
The utility model provides the technical proposal of a forced turbulent flow heat exchange tube. The proposal mainly comprises a heat exchange tube body. The proposal is characterized in that continuous and regular spiral grooves with inward indented outer surfaces are arranged on the tube body, the inner surface of the tube body is provided with a spiral dummy club corresponding to the spiral groove with an indented outer surface, and the cross sections of the spiral grooves adopt arc groove shapes. The proposal also has the concrete characteristic that the spiral groove adopts a single head spiral groove, and also can adopt a multi-head spiral groove. The cross section shapes of the spiral grooves adopt regular arc-shaped grooves.
Description
The utility model relates to the heat exchanger heat exchanger tube that carries out heat exchange, especially a kind of forced turbulent heat exchanger tube.
In the prior art, the employed heat exchanger tube of heat exchanger all is the tubing that adopts all size model, but because of there not being the coefficient of convective heat transfer problem of good treatment individual event medium, so have coefficient of heat transfer problem undesirable and incrustation on heat exchanger tube.
The purpose of this utility model is exactly at the existing in prior technology deficiency, and a kind of forced turbulent heat exchanger tube technical scheme is provided, and this scheme can improve the coefficient of heat transfer of heat exchanger tube greatly, and does not produce incrustation on the tube wall of heat exchanger tube.
This programme is realized by following technical measures.Mainly include the heat exchanger tube body, the characteristics of this programme are on described body, inwardly recessed continuous, regular helical groove of outer surface is arranged, inner surface of tube body then has the helical groove corresponding spiral boss recessed with outer surface, and the shape of cross section of described helical groove is a deep-slotted chip breaker.The concrete characteristics of this programme also have, and described helical groove is the single head helicla flute, or multi-head spiral groove.The shape of cross section of described helical groove is the deep-slotted chip breaker of a rule.
According to as can be known to the narration of such scheme, because in this scheme, on described heat exchanger tube body, inwardly recessed continuous, regular helical groove of outer surface is arranged, inner surface of tube body then has the helical groove corresponding spiral boss recessed with outer surface, and this just makes the heat exchanger tube inwall form rough spiral.When fluid is arranged when mobile in heat exchanger tube, part fluid is along the helicla flute rotational flow, most of fluid then is to flow along rough surface in the heat exchanger tube, this has just formed very strong turbulent flow, as long as choose the spiral fluted degree of depth and pitch, the coefficient of heat transfer of heat exchanger tube will increase substantially, but the not proportional thereupon increase of resistance has solved the contradiction that improves between the coefficient of heat transfer and the resistance increase effectively.Also, on the tube wall of heat exchanger tube, also be difficult to incrustation, so the while has also solved the problem of tube wall incrustation because the existence of turbulent flow is arranged.This shows that the utility model compared with prior art has substantive distinguishing features and progress, its implementation result also is conspicuous.
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
By accompanying drawing as can be seen, the forced turbulent heat exchanger tube of this programme, mainly include heat exchanger tube body 1, the characteristics of this programme are on described body 1, inwardly recessed continuous, regular helical groove 2 of outer surface is arranged, body 1 inner surface then has the helical groove 2 corresponding spiral boss recessed with outer surface, and the shape of cross section of described helical groove 2 is deep-slotted chip breakers.Described helical groove 2 can be the single head helicla flute, can be multi-head spiral groove also, and what present embodiment adopted is multi-head spiral groove.The shape of cross section of described helical groove 2 is deep-slotted chip breakers of a rule, and this deep-slotted chip breaker can be arc of circle or oval arc or parabola shaped arc.
