Cold Plate doubts

BorjaH

Hi there,

I've several doubts regarding the performance of the cold plate installed at CRD300DA12E-XM3 Three Phase Inverter (CP 3012 from Wieland).

·        Which is the maximum admissible flow rate? In the datasheet it seems to be 25 l/min. Is that right?

·        Which is the maximum coolant pressure?

·        Which is the power to be dissipated by the coolant when the inverter is working at maximum power (300kW) at a switching frequency of, for instance, 20 or 24 kHz?

·        In section 2.6 of the product datasheet it is said that "Maximum output power is de-rated when operating with coolant temperatures above 25ºC". Where can I find the definition of this re-rate?

·        Does the inverter by itself limit the performance for assuring that the mosfet respects the SOA (safe operating area) depending on the DC voltage and/or the switching frequency? Does the de-rate commented above related to this?

·        It is also mentioned that 50/50 mixture of water/ethylene glycol is suggested. But, in our case, we're no foreseeing to use the inverter in an ambient less than 0ºC. Is there any information about the performance when operating without glycol, 100% water or 100% deionized water?

Another question I have is: which is the low voltage power consumption?

Best regards,

Borja
