Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
Refer to shown in Fig. 2 to Fig. 4, in the present embodiment, a kind of wind generator heat radiation enhancement mode rotor magnetic pole, using 2MW electricity excitation direct driving wind driven generator rotor magnetic pole as test piece, is manufactured experimently.It comprises pole core 20, pole(cell) insulation 21 and pole coil 22, described pole(cell) insulation 21 is arranged between pole core 20 and pole coil 22, and described pole(cell) insulation 21 offers twice mounting groove 23, the heating panel 24 of " L " type is provided with in described mounting groove 23, and a side of described heating panel 24 inserts between described pole coil 22 by mounting groove 23, another side is drawn along pole(cell) insulation 21, heat is derived pole coil, described pole coil 22 totally five layers, when pole coil 22 coiling is to the second layer, the second layer is the high-temperature region core layer of described pole coil 22, the mounting groove 23 of heating panel 24 from pole(cell) insulation 21 is inserted, then coiling three is continued, four, five layers.
Described heating panel 24 be by the thick aluminium plate of 0.8 ~ 2mm through propelling the price of, punching press, the series of process process such as filling make, adopt the technology that propels the price of on aluminum sheet material, form the micro-channel grid that several internal mutuals are connected, the described micro-channel grid filling working medium of special filling process, finally form 1 ~ 3mm thick, the sheet-type device of collection heat transfer and heat sinking function and one, realizes connecting without interface from heating surface to radiating surface.Its heat-transfer capability accepted from thermal source can reach 200W/CM
2above.
Contrast test:
Be together in series by the rotor magnetic pole of normal wound rotor magnetic pole with band heating panel 24, connect DC power supply, two magnetic poles are with identical electric current electrified regulation simultaneously.The temperature of two magnetic pole different parts is recorded once every 30 minutes.Test data is as shown in the table.From test data, when two kinds of pole coils are heated to target temperature with equal conditions, both highest temperature differences reach 38.6 DEG C, and the cooling-down effect that heating panel 24 pairs of pole coils are described still very significantly, especially lower the temperature more obvious by the second layer of heating panel 24 both sides and third layer copper conductor.
By test, after heating panel 24 is added to 2.0MW electricity excitation direct driving wind driven generator rotor magnetic pole coil, reduction flat type copper wire wire gauge size, be reduced to 3.8X8 from 4.25X9.0, like this, the size of pole core 20 and pole(cell) insulation 21 can not be changed, originally every layer of coiling 16 circle, change wire gauge after every layer around 18 circles, total number of turns remains unchanged, and each coil can save electromagnetic wire consumption 20.5% (supposing that wire is constant).
Carry out contrast test to the pole coil after material-saving and primary coil, it is low about 5 DEG C that the pole coil maximum temperature point after test data shows material-saving compares primary coil.Not only reach the object of material-saving synergy, and performance also increases.
