You would expect so but the data about temperature anomalies suggests the opposite:

Minimum records being broken can mean more variance causing outliers more frequently, wouldn't necessarily mean that they push the average down as they might be short events followed by a different weather pattern.
The disruption of the polar vortex drops temperature significantly across Northern Europe but it can be caused by the warming of the atmosphere so even though it can cause record lows it is a short lasted event and on average the temperature is still going up.
That is also a side-effect of climate change, more powerful bursts of extreme weather.

Around 10 were broken in the last 3 decades which is more than the around 7 broken for the max temperatures. If more min records are broken, then I would expect the average to be going down not up.
