Abstract
The utility model discloses an improve spoiler that heat exchange efficiency's heat exchanger was used, it adopts the base member of plastics, has the spiral tooth's socket of distortion on the base member, compares with prior art, has advantages such as heat exchange efficiency height, long service life, with low costs, convenient assembling.
Description
The utility model relates to the flow spoiler that a kind of heat exchanger is used, and more particularly is a kind of flow spoiler that places in the heat-exchange tube.
As everyone knows, the heat transfer efficiency of advection or laminar flow is low.For improving heat exchanger,, in heat-exchange tube, insert a flow spoiler usually as the heat exchange efficiency of fan heater.This flow spoiler has two kinds of structures basically, and a kind of is to be pressed with the wrong wrinkle ripple of oblique on the matrix of sheet, and another kind is the pitch that longitudinally there is five equilibrium on the sheet metal surface, and concavo-convex hole and seam are arranged on each pitch.The flow spoiler of these band ripples or holes, seam can make the high temperature fluid by heat-exchange tube slow down, weaken the laminar flow effect in heat-exchange tube, and pipe is outer to be dispersed thereby the heat of high temperature fluid passed to by the heat exchange copper pipe as much as possible.Yet this class flow spoiler because metal materials such as matrix adopting aluminium matter or copper alloys, the hot and cold water in heat-exchange tube act on repeatedly with electrochemical action under, can corrosion form dirt, reduce heat transfer efficiency and blocking heat-exchanger pipeline; Next is that the flow-disturbing effect is not strong, by some wrinkle ripples or the concavo-convex hole on the matrix, can not make the fluid temperature (F.T.) in the same cross section of runner even, influences heat exchange; Be easily distortion, the bending in packed and transported of metallic matrix of sheet once more, both influenced assembling, can not make flow spoiler be in the less position of heat-exchange tube inner laminar flow again.
For this reason, the purpose of this utility model provides a kind ofly makes that heat exchanger heat exchange efficiency height, corrosion stability are good, long service life, cost are low, and novel flow spoiler easy to assembly.
The utility model be achieved in that on matrix, have distortion etc. pitch spiral-shaped teeth groove, this teeth groove can form spiral flow channel with the heat-exchange tube inner periphery of overcoat, fluid distance by heat-exchange tube is increased, high temperature fluid is in the rotation of runner high speed, and abundant and heat exchange tube wall transmission of heat by contact carries out heat exchange.
The cross section of above-mentioned matrix is thin " eyelid " shape of middle webbing, adopts heat resistant plastice, makes as modified polypropene.
The utility model has the advantages that: the average length of every circle spirality teeth groove is much longer than pitch on (1) matrix, the addendum envelope of teeth groove can be corresponding with the heat-exchange tube inner cylinder face, holdup time or the distance of high temperature fluid in heat-exchange tube prolonged, and heat exchange is abundant.Fluid rotates at a high speed through the spirality teeth groove simultaneously, and under centrifugal force and the effect of grooved surface component of reaction, high temperature fluid is pushed to tube wall, forms turbulent condition, makes the fluid each point temperature trend that is full of groove in the same cross section consistent, and heat exchanger effectiveness is improved; (2) flow spoiler employing cross section is that middle webbing thin " eyelid " shape and heat resistant plastice are made, and the spirality teeth groove through twisting plays the reinforcement effect, and integral body has elasticity and certain intensity, not yielding, be convenient to assembling, electrochemical reaction, long service life can not take place in plastics; (3) manufacture craft is simple, and is promptly plastic through reversing cooling from the still unhardened plastic tape that injection machine is extruded, can produce continuously, and the efficient height, with low cost.
Embodiment of the present utility model is provided by the following drawings and embodiment.
Fig. 1 is the structural representation of the utility model flow spoiler.
Fig. 2 is the cutaway view of Fig. 1 along A-A.
Referring to Fig. 1, the flow spoiler that heat exchanger is used has the matrix 1 that a heat resistant plastice is made, and the twin-feed spiral teeth groove 2 of distortion is arranged on the matrix, and the enveloping surface of tooth is and the corresponding face of cylinder of overcoat heat-exchange tube inner surface in the teeth groove.The cross section of described matrix 1 is thin " eyelid " shape of middle webbing, as shown in Figure 2, this shape can make the tooth top of the spirality teeth groove of formation approach, with the contact-making surface of minimizing with the heat-exchange tube inwall of overcoat, thereby increase heat exchange area, increased the elasticity and the intensity of flow spoiler integral body simultaneously, not yielding.Above-mentioned heat resistant plastice can be a modified polypropylene plastic.
This flow spoiler and the supporting use of heat exchanger, it places in the heat exchange copper pipe, and spiral alveolar on the matrix and copper pipe inner surface form the fluid passage.Work as high temperature fluid, when the helical flow path, just produce rotation at a high speed, under the double action of rotary centrifugal force and helicla flute curved surface component of reaction, fluid is turbulent condition by stirring as flow of hot water, makes the fluid temperature (F.T.) in the same cross section even, and heat exchange efficiency improves.
The utility model production technology is simple, the plastic tape distortion of the mecystasis that will extrude from injection machine, and the cooling forming intercepting gets final product then.
Claims (3)
1, the flow spoiler used of a kind of heat exchanger comprises a matrix, it is characterized in that having on the matrix spirality teeth groove of distortion; The matrix adopting plastic material is made.
2, flow spoiler according to claim 1, the cross section that it is characterized in that matrix are thin " eyelid " shape of middle webbing.
