Connection circulating pump and radiator coil tube on pipeline between arbitrary two end to end shells, the radiator coil tube are set by cooling
It is standby to cool down；The temperature sensor for further including programmable logic controller (PLC) and being arranged in transformer shell body, the temperature pass
Sensor is connect with programmable logic controller (PLC) inlet circuit, the electromagnetism of the programmable logic controller (PLC) output end and circulating pump
Valve circuit connects.
The cool principle of the heat sink is：Every group of radiating fin is placed in a shell filled with water, radiating fin is made
Piece impregnate in water, conduction oil be recycled to fin heat can by heat transfer by way of be transmitted in water, water absorb heat
Amount temperature increases under the forced circulation effect of circulating pump, and the water with heat is recycled to radiator coil tube, utilizes cooling system
It radiates to radiator coil tube so that the water water temperature drop exported through radiator coil tube, the water after water temperature drop are recycled into again
In each shell, the heat that each group radiating fin generates is taken out of.
Preferably, the heat-conducting medium is water.
Preferably, the cooling system is cooling fan, the cooling fan and radiator coil tube are staggered relatively.It may insure wind
Cold effect.
Preferably, the programmable logic controller (PLC) output end is connect with cooling fan circuit.Programmable logic controller (PLC)
The operation of cooling fan can be controlled.
Preferably, at least one side is ripple struction on each shell.The side of ripple struction can increase shell
The heat exchange area of body and air, improving radiating effect.
The beneficial effects of the utility model are：
1, the mode of Temperature fall is significantly faster than heat conduction velocity by way of water-bath, water is being recycled plus circulating pump
Facilitation, therefore may be implemented that heat sheds within a short period of time, be damaged caused by avoiding transformer overheat.
2, the effect of shell has two aspects, on the one hand can store water, and there is no need in addition setting water tank；On the other hand
Shell can play the role of protective cover, radiating fin using and transportational process in often collide deformation, pass through shell
The protection of body can play a protective role to radiating fin.
3, using by heat draw cooling by the way of thus only need be arranged a cooling fan, reduce cost, and
Existing wind cooling temperature lowering mode needs every group of radiating fin to install a cooling fan, and cost is higher.
4, multigroup radiating fin may be implemented while cooling down, since the temperature of temperature-reducing medium passes through cold wind in cyclic process
Fan implements cooling, it is possible to ensure that the temperature-reducing medium entered in shell is in a relatively low temperature, to ensure drop
Temp effect.
