How to transfer files from broken chromebook to new chromebook?

My Lenovo Chromebook broke to the point where i couldn't even turn it on, I have a new hp Chromebook but I've lost all my files that i saved to that one (4000, all pretty important image files) and i thought they'd save onto the cloud so that whichever chromebook i logged into after that, i could regain the files instantly but apparently not. How does it actually work? Can i ever get the files back from my broken chromebook without external storage? It isn't working because water ruined the inside so i can't just briefly go on it and transfer them onto a hard drive then into the new computer or something, is there any other way?
