Gilled radiator is the mainstream radiator of current transformer, and radiating efficiency is very high, but with transformer function
The continuous increase of rate, the heat that iron core generates is increasing, and temperature of oil in transformer is caused constantly to increase, and every liter of the temperature of transformer
6 degrees Celsius high, the insulating materials service life of iron core winding will halve, but the expense for developing radiating fin is again very high, and one
As can only be produced into the original heat-sinking capability for increasing radiator by increasing heat dissipation area and improving.
In view of the foregoing, it is necessary to which designing one kind can effectively mention on the basis of not increasing heat dissipation area and production cost
The ripple oil duct gilled radiator of high heat dissipation effect.For this purpose, the applicant has made beneficial design, technology described below
Scheme generates in this background.
Summary of the invention
The purpose of the present invention is to provide a kind of ripple oil duct gilled radiator, help to optimize oil channel structure and produced
Raw Secondary Flow is sufficiently mixed transformer oil, thus augmentation of heat transfer and be improved heat dissipation effect, help to save production cost
With the raising market competitiveness.
The purpose of the present invention is in this way to reach, a kind of ripple oil duct gilled radiator, including an oil inlet pipe, one fuel-displaced
Pipe and one group of cooling fin for being arranged between oil inlet pipe and flowline and being connected to respectively with oil inlet pipe and flowline, the heat dissipation
Piece is formed by welding by a pair of of heat sink by edge, it is characterised in that: the heat sink is spaced is suppressed with number in the width direction
A waveform area has respectively constituted a Welding Area again between several waveform areas, and a pair of of heat sink mutually welds between opposite Welding Area
Connect fixed and by several interruption-like separations in waveform area, a pair of of heat sink has complemented each other to form a wave between opposite waveform area
The section of line oil duct, the ripple oil duct is wavy and the distance between two sides heat sink is identical.
In a specific embodiment of the invention, it is respectively formed at the cooling fin upper and lower ends by heat sink
There is an opening, the opening is connected to the oil inlet pipe of upper and lower ends and flowline respectively.
In another specific embodiment of the invention, described oil inlet pipe one end is formed with an oil inlet, described
One end of flowline is formed with an oil outlet.
In another specific embodiment of the invention, the bending radius phase of each flexure plane in the waveform area
Together.
Of the invention there are one in specific embodiment, the waveform area is suppressed by the way of punching press or roll-in
It forms.
The present invention with the above structure, it has the advantages that firstly, since using and forms ripple on a heat sink
The structure of oil duct, it is thus possible to generate transformer oil when passing through and rotate and cause Secondary Flow, to be sufficiently mixed transformer
Oil improves convection transfer rate, and then improving radiating effect, prolongs the service life；Secondly as using only traditional compacting
Technique, thus research and development and production cost have been saved, effectively improve the market competitiveness；Third, since ripple oil duct chip dissipates
Hot device has stronger heat dissipation performance, transformer manufacturers mountable lesser amt or smaller in the case where identical heat radiation power
The radiator of specification reduces the disposable investment of client.
