Captain experiences a left cowl a/I warning message during descent for landing and elects to divert ...

Narrative:

We received a left cowl a/I warning message. This is a repeat write up on this plane (reported to be 6 priors by the mechanic). We had to divert due to ZZZ1 not being a suitable destination. We were trying to find our best option. Flight ops wanted us to land as close to ZZZ1 as possibly. Every option they gave us would have had us descending through ice. After an extensive time of the first officer and I doing our own research on the plane we realized that our only option was ZZZ. We diverted. In order to do this research I had to connect to the aircraft internet and go to the NOAA webpage. I had no real support from flight ops. Not fixing the plane. There was a rather large hole in a duct. Flight ops should be finding a good place to divert. We actually waited a long time to contact them because often they will mislead you.

Title: Captain experiences a L COWL A/I warning message during descent for landing and elects to divert to a suitable airport without icing in the forecast. The aircraft had a history of six previous similar writeups and Dispatch was not helpful in finding an alternate.
