A cooling fan - — New energy inverter cooling fan replacement plan

by:TOCH     2021-01-27
【 A cooling fan application demands 】 :


the original new energy inverter models is EBM - equipment with a cooling fan R2E225 - BD92 - 09, now demand optimization with 2 a cooling fan to replace 1 EBM fan, and long life.








original equipment of cooling fan: EBM - R2E225 - BD92 - 09 number 4 PCS ( Each reactor 1 PCS)


a cooling fan to replace scheme selection basis: according to R2E225 - BD92 - 09 fan PQ curve comparison







fan PQ characteristic curve of reference:







a cooling fan to replace model solution a:


a cooling fan action points: such as above, green and red PQ curve, the greater the wind resistance red line 9 lg1448p5g001 fans have an advantage more.


the cooling fan selection: choose the yankees fan 9 lg1448p5g001 SanAce mountain * 2 PCS in parallel with the


advantage: the cooling fan long life 180000 h / 60 ℃


disadvantages: installation should be changed structure





a cooling fan to replace model scheme 2:


a cooling fan action points: green R2E225 - BD92 - 09 and blue ( 9TS48P0H001) PQ characteristic curve is almost parallel, can completely replace the fan.


风机:选用9TS48P0H0001


优点:散热风扇尺寸一样,安装不需改变结构,可直接替代


缺点:风机寿命只有40000H/60℃,相对不够长


注:风机可增加温控器只能检测与调速,低温时低速运行,节能延长寿命





方案一:


散热风扇安装要求:


1、此面以上器件及钣金拆除






2、此面板圆孔改下图尺寸,开孔2个






3、安装示意图








4、注意事项


固定风扇的面板与冷凝器之前安装有缝隙,需尽可能密封不要漏风。



accessories


1, the DC power supply


constant-voltage power supply: Vout: 48 v


1 power supply with 1 fan


output current allowance is big good


2, thermostat, Optional)


the fan with PWM speed regulating function, reactor temperature thermostat through real-time detection, output PWM signals intelligence control, control of the cooling air volume, the fan is not worked in the maximum speed, not only can save electricity and noise reduction, but also can prolong the service life of the fan.


3, fan fence





new energy inverter requirements of the fan is stable and reliable, long life, combined with the working environment temperature is higher, so the recommendation from the limited one, the use of the axial flow fan 60 ℃ environment, their life over 180000 hours; With two fans in parallel, and can reduce the damage rate is low.


if you want to consider to install, can choose 2 centrifugal fan, but it is strongly recommended that match the thermostat is used, through the intelligent control of motor speed, derating use and prolonging life.


thank you for reading, and do a cooling fan chi automotive professional, professional research and development production of cooling fans, dc fan, centrifugal fan, blower and cooling fan manufacturers, have our own r&d team and agent Japan SanAce mountain the cooling fan, Jamicon kaimei cooling fans, AVC fan, welcome to come to consult, thank you!
