Description

Non-homogeneous oil duct gilled radiator
Technical field
The utility model belongs to oil-filled transformer component technology field, and in particular to a kind of non-homogeneous oil duct chip radiating Device.
Background technology
As is known in the industry, need to be in oil-filled transformer body in order to ensure oil-filled transformer is able to run steadily in the long term The both sides of long side direction configure gilled radiator, radiator and oil by means of flange connection or other similar connected modes The conduction oil formation circulation cooling circuit of immersion inside transformer, plays the work to the iron core cooling inside oil-filled transformer With, controlled the temperature rise of oil-filled transformer, ensure power supply-distribution system it is normal with it is safe.
It is no lack of the technical information on gilled radiator, such as CN201084519Y in disclosed Chinese patent literature(Become Depressor gilled radiator)、CN201229827Y(Stair type heat radiator of heat radiating fins)、CN201185117Y(The chip of transformer Radiator)、CN201185118Y(The radiator of transformer)、CN201185115Y(Radiator with fan seat)、 CN201256051Y and CN101388275A(Using the transformer heat exchanger of evaporation cooling technique)、CN202394651U(Transformation Device gilled radiator)、CN201331277Y(Fin type heat radiator for transformer)、CN101930829A(A kind of oil-filled transformer Radiator)、CN203642770U(Gilled radiator)And CN204286154U(A kind of oil-filled transformer cooling is dissipated with chip Hot device), etc..
And then as is known in the industry, the fluid temperature of oil-filled transformer can effectively be reduced by improving the heat transfer property of gilled radiator Degree, improves working environment and extends the service life of oil-filled transformer.In addition, radiating efficiency and the radiating of gilled radiator The improvement of effect can reduce the specification of gilled radiator or even reduce the quantity of gilled radiator, can not only save to money The consumption in source, and the cost of oil-filled transformer can be reduced.
By the reading to being not limited to patent document exemplified above, deposited in the structure design of gilled radiator It is uniform in the oil duct of common ground, i.e. gilled radiator, specifically, is implemented in(It is formed in)On same gilled radiator Plural bar oil duct(Oil duct is also referred to as " oil groove ", as follows)Cross-sectional area be it is equal, this structure have is simplified use In the strong point of the mould of shaping fin, and both got back for a long time by the approval as the law of radiator production firm The accreditation of transformer user, especially, had not only had no but also had not heard the report that any query is proposed to this impartial oil channel structure so far Road.But many experiments made through the applicant think that uniform oil duct at least has following technical problem:Because radiator exists During actual military service, the oil mass received positioned at the oil duct of fin two side areas receives than the oil duct positioned at central region Oil mass it is small, thus abundance of the fluid in the oil duct of two side areas and central region is uneven, then two side areas The radiating efficiency and radiating effect relative mistake of oil duct, influence the operating efficiency of whole radiator, or even influence the use of transformer Life-span.Additionally due to the design concept as the law of uniform oil duct also produces and following attempts to solve but so far all the time fail solution Puzzlement certainly:The factor consideration such as space constraints when being installed due to transformer user for cost factor and electric power facility, because And require transformer production manufacturer and reduce specification or even the reduction of radiator as far as possible on the premise of radiating effect is ensured The quantity of radiator, but facts have proved that bear's paw can not get both with shark's fin.
For above-mentioned technical problem, the applicant has made beneficial design, and technology described below is formd finally Scheme, and test center in the case where taking secrecy provision in the applicant tested, and is as a result proved to be practical 's.
