Abstract

The utility model discloses a heat transfer pipe for heat exchange, which comprises a pipe body (1). The inner wall (3) of the pipe body (1) is provided with a spiral steel wire (2) extending along the direction of the pipe, and the spiral steel wire (2) is pasted onto the inner wall (3) of the pipe body. By the aid of the spiral steel wire (2) pasted onto the inner wall (3) of the pipe body, liquid in the pipe body (1) flows irregularly and turbulently, the thickness of a boundary layer is decreased, fluids rotate irregularly through the spiral steel wire (2), the temperatures of the fluids on all portions of the internal cross section of the pipe body (1) tend to be uniform, heat exchange is reinforced, heat transfer area is also increased, heat conduction and dissipation are accelerated, so that heat transfer performance is improved remarkably, the performance of a whole heat exchanger is enhanced, the size of the heat exchanger is reduced, and the number of heat transfer pipes for heat exchange used in the heat exchanger is decreased.

Description

The heat exchange heat-transfer pipe

Technical field

The utility model relates to a kind of heat transfer unit (HTU) of heat exchanger, is specifically related to a kind of heat-transfer pipe that two kinds of fluid at differing temperatures are carried out heat exchange.

Background technology

The evaporimeter of air-conditioning, refrigerator, refrigeration system, condenser, cooler all have two kinds of fluid at differing temperatures are carried out heat exchange in heat exchanger a process, and the important spare part of heat exchanger is a heat-transfer pipe.The heat exchanger of common in the market external and domestic production, all adopting the copper pipe of inside and outside smooth surface is heat-transfer pipe, this ganoid heat-transfer pipe, flowing of medium is laminar flow in its pipe, there is a boundary-layer in surface at tube wall, and laminar flow and boundary-layer will influence the heat exchange efficiency of two kinds of different temperatures fluids.For reaching certain heat exchange effect, heat exchanger just needs to increase the quantity of heat-transfer pipe, cause the increase of heat exchanger volume, and the consumption of heat-transfer pipe increases simultaneously.

The utility model content

The utility model has overcome the deficiencies in the prior art, and a kind of enhanced heat exchange process is provided, and obviously improves the heat exchange heat-transfer pipe of heat exchange property.

For solving above-mentioned technical problem, the utility model by the following technical solutions:

A kind of heat exchange heat-transfer pipe comprises pipeline body, and the inner tubal wall of described pipeline body is provided with the steel wire that is used to stop liquid flow that extends along duct orientation.

In order to realize the utility model better, make further technological improvement below:

As preferably, described steel wire and sticks on the inner tubal wall of pipeline body twist.

As preferably, described spirality steel wire is that the six roots of sensation is evenly distributed on the inner tubal wall of pipeline body.

Heat exchange heat-transfer pipe of the present utility model can also be following technical scheme:

The wall of the inner tubal wall of described pipeline body is the waveform of ring-type.

Compared with prior art, the beneficial effects of the utility model are:

By adopting project organization of the present utility model, what make liquid in the pipeline body mobilely becomes irregular turbulent condition, reduced the thickness of boundary-layer, the spirality steel wire that is provided with on the pipeline body inner tubal wall, make fluid produce irregular rotation, the temperature of each several part fluid reaches unanimity on the interior cross section of pipeline body, strengthened heat exchanging process, and increased heat transfer area, quicken the conduction of heat and distributed, thereby made heat transfer property obtain significant raising, thereby improved the performance of whole heat exchanger, dwindle heat exchanger volume, saved the usage quantity of heat exchange heat-transfer pipe in heat exchanger.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the inner tubal wall cross-section structure structural representation of the utility model pipeline body.

Wherein, the pairing name of the Reference numeral in the accompanying drawing is called:

The 1-pipeline body, 2-steel wire, 3-inner tubal wall.

The specific embodiment

Below in conjunction with embodiment the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.

As depicted in figs. 1 and 2, a kind of heat exchange heat-transfer pipe comprises following critical piece:

Pipeline body 1, steel wire 2, inner tubal wall 3.

The annexation of above-mentioned parts is:

A kind of heat exchange heat-transfer pipe comprises pipeline body 1, and the inner tubal wall 3 of described pipeline body 1 is provided with the steel wire 2 that extends along duct orientation; Above-mentioned steel wire 2 twist and stick on the inner tubal wall 3 of pipeline body; Above-mentioned spirality steel wire 2 is evenly distributed on the inner tubal wall 3 of pipeline body for the six roots of sensation; The wall of the inner tubal wall 3 of above-mentioned pipeline body 1 is the waveform of ring-type.

The operation principle of the device in the present embodiment is:

Stick on the spirality steel wire 2 on the inner tubal wall 3 of pipeline body, what make liquid in the pipeline body 1 mobilely becomes irregular turbulent condition, reduced the thickness of boundary-layer, spirality steel wire 2 also makes fluid produce irregular rotation, the temperature of each several part fluid on the pipeline body 1 interior cross section is reached unanimity, strengthened heat exchanging process, and increased heat transfer area, quickened the conduction of heat and distributed, thereby make the performance of transmitting of conducting heat obtain significant raising, thereby improved the performance of whole heat exchanger, dwindled heat exchanger volume, in heat exchanger, saved the quantity of the use of heat exchange heat-transfer pipe.

In sum, just can realize the utility model preferably.
