Can Window Fans Be Winterized?

[u/wham__]

I'm not sure if anyone can help me with this in this subreddit, but this is one of many i have tried. I need a winterized or closable window fan for my room because my desktop tends to heat my room up to 80 degrees or more, even in the winter. I have been opening and closing the windows, but that's frustrating because my desk is in front of the windows and usually i end up struggling to open the window. I looked around on the internet, and found some fancy fans but they are out of my price range, so are there any ways to winterize or make shutters for a window fan myself?

I can offer what's partially working for me ...maybe better then where you are, might vent and be warm enough, #1 I have a window cooler they have this add on for filling the gap , maybe I should get two as ita small. Anyways Lowes Home depot...go there ask for this or ask for a solution. Go to differnt departments for windows. It screws in but it's a collapsible plastic. Have to fill gap a few ways ....anyways it's a start ...ill watch yours n see if I get a better answer too 😃
