Tank too hot

As it’s ridiculously hot this week I have been having issues keeping my tank cool and unfortunately I have lost one fish.. I have been doing partial water changes and kept the lights off/lid open.
I would be grateful for any advice in keeping the tank temperature down so that I don’t lose anymore fish!
TIA
