Description
Technical field
This utility model relates to chemical production equipment field, is specifically related to a kind of modified model augmentation of heat transfer equipment.
Background technology
Developing rapidly the critical shortage with the energy due to science and technology, make the degree of depth that heat transfer enhancement technology study and range expanding day and to new field infiltration with develop, this has all been carried out substantial amounts of research and development by each key industry state of the world.The structure of heat exchanger adds plain tube from original segmental baffle and develops into supporter between pipe and add shaped enhanced tube, and heat transfer and fluid friction property have had and be obviously improved, and has high temperature resistant, high pressure resistant, simple in construction, the advantage such as easy to clean.The structure of various special pipes is different, but its enhanced heat transfer mechanism is similar, is all that pipe carries out various trickle processing, to being formed with the projection of rule distribution on tube wall, or tube wall is made ripple or helical groove vertically.Projection variously-shaped on heat-transfer area, is the promotion body of passive disturbance, can continue again to block Development of Boundary Layer.
The thickness of the processing exchange heat pipe of conventional helical pipe, the degree of depth of screw thread etc. has a restriction, and affect the intensity of heat exchanger tube, how to determine the coefficient of heat transfer accurately and effectively, and the long-term of heat transmission equipment efficiently etc. is also all difficult to ensure that.
Utility model content
For the problem such as overcome existing augmentation of heat transfer equipment intensity limited and film coefficient of heat transfer is low, the invention provides a kind of modified model augmentation of heat transfer equipment.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
A kind of modified model augmentation of heat transfer equipment, including heat exchange tube body, heat exchange tube body outer surface is wound with spiral winding, is provided with the first interposer and the second interposer, the first interposer and the second interposer and is welded on heat exchange tube body inwall by support inside heat exchange tube body；The first described interposer is arranged on the import department of heat exchange tube body, and the second described interposer is arranged on the exit of heat exchange tube body.
Preferably, described spiral winding is metal material.
Preferably, the first described interposer and the second interposer are all toroidal, and the radius of heat exchange tube body is 2 times of the first interposer helical tube body radius, helical tube body radius is the first interposer 1 ~ 2 times of the second interposer.
Preferably, there is equally spaced groove on described heat exchange tube body surface.
Pass through technique scheme, what this utility model obtained has the beneficial effects that: spiral winding is used in the outer surface of heat exchange tube body, play the effect of serpentine pipe, namely the effect of augmentation of heat transfer is reached, equally can have phase transformation and without the diabatic process of phase transformation in significantly increase the film coefficient of heat transfer that pipe is inside and outside, also solve the processing limitation of corrugated tubing thickness and the depth of thread simultaneously, reach the optimization produced, createing maximum value with limited resource, the groove above heat exchange tube body can with the spiral winding of well fixing heat exchange tube body outer surface；When the circulation area of heat exchange tube body import and export is equal, due to the impact expanded with heat and contract with cold, the flow velocity of circulation can be different, affect the film coefficient of heat transfer of heat exchanger equally, adopt the interposer of two different volumes, making the fluid in tube side present at the uniform velocity state, film coefficient of heat transfer is always maintained at higher state.Spiral winding and interposer comprehensively use, and can reach the maximization of film coefficient of heat transfer, augmentation of heat transfer best results.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Below in conjunction with embodiment and detailed description of the invention, this utility model is described in further detail.
Embodiment.
As shown in Figure 1, Figure 2 and Figure 3, a kind of modified model augmentation of heat transfer equipment, including heat exchange tube body 1, heat exchange tube body 1 outer surface is wound with spiral winding 2, heat exchange tube body 1 is internal is provided with the first interposer 3 and the second interposer 4, and the first interposer 3 and the second interposer 4 are welded on heat exchange tube body 1 inwall by support；The first described interposer 3 is arranged on the import department of heat exchange tube body 1, and the second described interposer 4 is arranged on the exit of heat exchange tube body 1；Described spiral winding 2 is copper；The first described interposer 3 and the second interposer 4 are all toroidal, and the radius of heat exchange tube body is 2 times of the first interposer helical tube body radius, and the second interposer 4 serpentine pipe radius is 1.5 times of the first interposer 1.There is equally spaced groove 5 on described heat exchange tube body 1 surface.After tested, the inside radius of groove is 1.5 millimeters, and outer radius is 3 millimeters, and spiral winding 2 winding effect is best.
When carrying out augmentation of heat transfer work, owing to spiral winding 2 is wrapped on heat exchange tube body 1 outer surface, the groove on heat exchange tube body 1 surface secures spiral winding, considerably increases heat exchange contact surface area, and heat exchange tube body 1 intensity is unaffected simultaneously；The volume of the second interposer 4 is different, makes the state that flow velocity that the fluid in heat exchange tube body 1 is avoided bringing is different owing to expanding with heat and contract with cold so that film coefficient of heat transfer is always maintained at higher state.
Above-described is only the preferred implementation of a kind of modified model augmentation of heat transfer equipment of this utility model; should be understood that; for the person of ordinary skill of the art; under the premise creating design without departing from this utility model; can also making some deformation and improvement, these broadly fall into protection domain of the present utility model.
