The outside of gripping at iron up and down is respectively arranged with lower carriage, and last core through screw rod passes that iron is gripped and upper bracket, and following core through screw rod passes down that iron is gripped and lower carriage, is respectively arranged with a plurality of stretching screws between about outside the last lower carriage.
The external form of described water-cooled iron core radiator is " day " font, adopts the aluminium alloy hollow board making, and two ends connect iron core water-cooled water inlet pipe and iron core water-cooled outlet pipe respectively.
The lead of described winding adopts the copper pipe or the aluminum pipe of hollow flat, at the two ends connection winding water-cooled water inlet pipe and the winding water-cooled outlet pipe of pipe, and pipe outer wall bag empire cloth, turn-to-turn embedding insulating epoxy glue, winding outside embedding insulating epoxy glue.
The utility model compact conformation, high, the good heat dissipation effect of electrical insulation properties are compared under the condition of equal electric current inductance value with the reactor of prior art, and in light weight, volume is little.
