Abstract
The invention discloses a winding conduit for water-cooling power equipment, which comprises a metal pipe body, wherein an insulating layer for preventing cooling liquid from corroding the metal pipe body is arranged on the inner wall of the metal pipe body, and the insulating layer is a Teflon material coating. The invention reduces the strict requirement on the cooling liquid of the power equipment, particularly the reactor, improves the corrosion resistance of the metal conduit to the cooling liquid, reduces water resistance and simultaneously improves the cooling efficiency, so that the water cooling system of the power equipment is simple and convenient to maintain and is more suitable for severe environments.
Description
[technical field]
The present invention relates to a kind of winding conduit, relate in particular to a kind of winding conduit that is used for water-cooling electric equipment.
[background technology]
The present water-cooling system of the reactor of power industry, lead, electrical device, by cooling fluid through the water route circulation heat and the external world that device produces carried out heat exchange, reach cooling effect.This type of cooling radiating efficiency height can satisfy the radiating requirements of bulk power system.But owing to directly contact between water route and the pipe inner wall, cooling fluid can produce corrosion to metal catheter, be easy to like this cause between the electrical device that connects in the water route and produce short circuit, in order to address this problem, generally need be to the cooling fluid deionization, purity requirement is also higher, run duration, in order to keep the high impedance rate and the purity requirement of cooling fluid, need install deionization and filter additional, but these attachment devices bring thereupon is the inconvenience that cooling system is safeguarded.Adopt the power equipment of this water-cooling pattern can not adapt to adverse circumstances, and have short-circuit risks between device; Cooling fluid in the water route also can be produced hydrogen, oxygen bubble by the voltage drop electrolytic ionization at winding two ends, reduces cooling effectiveness.
[summary of the invention]
The objective of the invention is in order to overcome weak point of the prior art, a kind of winding conduit that is used for power equipment, particularly water cooling reactor that cooling fluid requires that effectively reduces is provided.
For achieving the above object, the present invention has adopted following technical proposal:
The winding conduit that is used for water-cooling electric equipment comprises a metal body, it is characterized in that being provided with on the inwall of described metal body the insulating barrier that prevents cooling fluid corroding metal body.
The aforesaid winding conduit that is used for water-cooling electric equipment is characterized in that described insulating barrier is the Teflon material coating.
The aforesaid winding conduit that is used for water-cooling electric equipment is characterized in that the profile of described metal body is square body.
The aforesaid winding conduit that is used for water-cooling electric equipment is characterized in that the profile of described metal body is cylinder.
The aforesaid winding conduit that is used for water-cooling electric equipment, the metal base that it is characterized in that described metal body is an aluminium.
The aforesaid winding conduit that is used for water-cooling electric equipment, the metal base that it is characterized in that described metal body is a copper material.
The aforesaid winding conduit that is used for water-cooling electric equipment is characterized in that described power equipment is a reactor.
The aforesaid winding conduit that is used for water-cooling electric equipment is characterized in that described power equipment is a transformer.
As improvement of the present invention, the application of inboard wall of tube body insulating barrier, effectively reduce of the harsh requirement of reactor water-cooling system to cooling fluid, prevent that cooling fluid is by electrolysis in the water route, reduce the additional cycle of cooling fluid, the thermal conductivity of gas content and then raising cooling fluid realizes the cooling effect to reactor more efficiently in the minimizing cooling fluid, has reduced the cost of water-cooling system; Simultaneously because the property of Teflon material, improved the metal base conduit to the corrosion resistance of cooling fluid, reduced water resistance, further improve cooling effectiveness.
Adopt the present invention, make water-cooling system easy maintenance, water cooling reactor also more be adapted to lack of water and other abominable applied environments.

Fig. 1 is a cutaway view of the present invention.
Fig. 2 is a user mode schematic diagram of the present invention.
[embodiment]
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
The winding conduit that is used for water-cooling electric equipment as illustrated in fig. 1 and 2 comprises a metal body 1, can flow for cooling fluid 3 in the described metal body 1, is provided with the insulating barrier 2 that prevents cooling fluid 3 corroding metal bodys on the inwall of described metal body 1.
Described insulating barrier 2 is Teflon material coatings, and wherein said Teflon Polytetrafluoroetylene is called for short Teflon, PTFE, F4 etc., and English name is Teflon.Owing to carry out thin-walled coating processing formation insulating barrier 2 at the inwall of metal body 1 with Teflon, the inwall and the cooling fluid 3 of metal body 1 are separated, make metal body 1 inwall have anticorrosive, the characteristics that water resistance is little, simultaneously insulating barrier 2 effectively reduces the lead both end voltage and falls electrolysis to cooling fluid 3, reduce the air bubble content in the cooling fluid 3, avoided taking place the danger of chemical reaction; The purity of cooling fluid 3, deionizing degree are required to reduce greatly, overcome the low inferior position of its thermal conductivity, reach the effect of good heat radiating when making the long-time safe operation of cooling fluid 3.
The external shape of described metal body 1 can be square body or cylinder.
The metal base of metal body 1 of the present invention can be aluminium or copper; handle by the inwall of metal body 1 being carried out the thin-walled coating with Teflon; form insulating barrier 2 between the inwall of metal body 1 and cooling fluid 3, protection metal body 1 has reduced the deionization requirement of cooling fluid 3 when not being corroded.
Described power equipment can be reactor or transformer, can be other power equipments that need water-cooled.
Embodiments of the invention are water cooling reactors.
