Liquid cooling inverter

NOTICE

Material Damage!

Material damage due to overheating!

The inverter is intended solely for operation in a closed cooling circuit with a heat exchanger. Operation without the specified liquid cooling system is not permitted. The inverter will overheat, causing it to be destroyed.

Preventive measures:

  • Only operate the drive system with the specified cooling system

 

The liquid-cooled cold plate is used to dissipate the power loss from the power electronics of the inverters.

The cold plate consists of a heat sink made from an AlMgSi 0.5 aluminum alloy with an integrated cooling channel. The heat is dissipated via the water that is routed through the cold plate.

 

The surface temperature of the liquid-cooled cooling plate must be < 40 °C (104 °F).

 

NOTICE

Material Damage!

Material damage due dew forms!

When the surface temperature of the cooling plate drops below the dew point, the water which bound in the air, condenses on the surface. The dew point depends on the ambient temperature and the humidity.

Preventive measures:

  • The flow temperature of the coolant must be designed based on the dew point table so that the surface temperatures of the cooling plate not fall below the dew point and there is therefore no condensation. (see dew point table)

 

Minimum requirements:

The specified rated data (see: chapter 'Technical data - inverter') are only under the following conditions:

 

The power loss from the control electronics is not dissipated via the cold plate.

The ambient temperature must not > 40 °C (104 °F).

The heat that arises has to be extracted separately.
