Description
Technical field
The utility model is related to condenser technology field, more particularly to a kind of screw thread condenser tube.
Background technology
Condenser is the parts of refrigeration system, belongs to one kind of heat exchanger, gas or steam can be transformed into liquid, will be cold
Heat in condenser pipe, in the way of quickly, is passed in the air near condenser tube.
Condenser tube in the market typically uses smooth equal diameter inwall, using the condenser tube of this inwall,
Its effective heat exchange area is smaller, liquid flows faster in condenser tube, and easily forms laminar flow, causes changing for condenser tube
The thermal efficiency is relatively low, and refrigeration is not good, and its application in market is limited to.
In addition, existing condenser tube is usually copper pipe, its cost of manufacture is higher.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of screw thread condenser tube, solves the heat exchange effect of condenser tube
Rate is relatively low, and refrigeration is not good, and cost of manufacture it is higher the problem of.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of screw thread condenser tube, including condenser tube outer wall, condenser tube internal wall and cavity, the condenser tube outer wall
Section be equal diameter circle, be provided with shape between some threads, the thread along around tube wall in the condenser tube internal wall
The cavity flowed for liquid, the condenser tube outer wall and condenser tube are formed into thread groove, in the condenser tube internal wall
Tubing between inwall uses iron pipe.
Further, the width of the thread is 0.6~0.65mm.
Further, the width of the thread is 0.65mm.
Further, the height of the thread is 0.15~0.2mm.
Further, the height of the thread is 0.15mm.
Further, the width of the thread groove is 0.6~0.65mm.
Further, the width of the thread groove is 0.6mm.
It is and smooth due to being provided with some threads along around tube wall in condenser tube internal wall using above-mentioned technical proposal
Equal diameter inwall compare, the effective heat exchange area of condenser tube can be increased by being threaded tooth, liquid in Cavity Flow, by
In the interference of thread, liquid flow velocity reduction, while easily forming turbulent flow, improves the heat exchange efficiency of condenser tube, with up to
To more preferable refrigeration.Because the tubing between condenser tube outer wall and condenser tube internal wall uses iron pipe, with using copper pipe
Condenser tube compare, the utility model cost of manufacture is relatively low.

Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that
Explanation for these embodiments is used to help understand the utility model, but does not constitute to restriction of the present utility model.This
Outside, as long as technical characteristic involved in each embodiment of the utility model disclosed below does not constitute conflict each other
It can just be mutually combined.
As depicted in figs. 1 and 2, a kind of screw thread condenser tube disclosed in the utility model, including it is condenser tube outer wall 1, cold
Condenser inside pipe wall 2 and cavity 3, the section of condenser tube outer wall 1 are justified for equal diameter, are set in condenser tube internal wall 2 along around tube wall
Have and form what is flowed for liquid between some threads 201, thread 201 in formation thread groove 202, condenser tube internal wall 2
Cavity 3, the tubing between condenser tube outer wall 1 and condenser tube internal wall 2 uses iron pipe.
Fig. 3 shows the structural representation of condenser tube internal wall in the utility model.The utility model is in condenser tube
Tooth 201 is threaded on wall 2, compared with smooth equal diameter inwall, the effective of condenser tube can be increased by being threaded tooth 201
Heat exchange area, liquid is when cavity 3 flows, due to the interference of thread 201, liquid flow velocity reduction, while easily being formed
Turbulent flow, improves the heat exchange efficiency of condenser tube, to reach more preferable refrigeration.
Thread 201 in condenser tube internal wall 2 be made by tuber (not shown) and screwed pipe pinch roller 4 and
Into.The structure of screwed pipe pinch roller 4 is as shown in figure 4, the surface of screwed pipe pinch roller 4 is provided with and the spiral shell in condenser tube internal wall 2
The pinch roller screw thread 401 that line tooth 201 matches, as shown in Figure 5.During making, screwed pipe pinch roller 4 is arranged on tuber, to control
The height of thread 201 processed；Tuber is started, makes tubing start to walk about on screwed pipe pinch roller 4；Tubing enters while walking about
Row welding, makes the thread 201 produced inwardly, forms condenser tube internal wall 2, the another side of tubing is then formed outside condenser tube
Wall 1, makes tubing reach required intensity, can bear more than 6MPa pressure by welding.
The width W of thread 201 is 0.6~0.65mm, preferably 0.65mm, the height H of thread 201 for 0.15~
0.2mm, preferably 0.15mm, the width L of thread groove 202 is 0.6~0.65mm, preferably 0.6mm.The width of thread 201 and
The width of height and thread groove 202 determines that the width of thread 201 is less than 0.6mm by test of many times, or
Highly it is less than 0.15mm, or the width of thread groove 202 is less than 0.6mm, can make the interference effect of thread 201 not
Greatly, liquid flow velocity reduction is not obvious, and refrigeration is not good；When the width of thread 201 is big more than 0.65mm, or height
When 0.2mm, or thread groove 202 width are more than 0.65mm, screwed pipe pinch roller 4 makes the inconvenience of thread 201, even
Making does not come out.
Embodiment of the present utility model is explained in detail above in association with accompanying drawing, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, it is right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall within protection domain of the present utility model.
