Was she standing on concrete? Her little feet could have been burning and she was hiding under the van due to the shade keeping the concrete a little cooler. If you think your pup is getting that hot, you could have put water on her to cool her off. We usually take my chi boating with us, but if it's gonna be in the 90's, I will leave her home. Being your pup is only 7 weeks, she was probably really hot and tired as they tend to nap a lot at that age. Check her pads to see if they're blistered. It's always wise to consider not taking them outside when the temperature is too hot since they are wearing coats. Dogs can overheat very quick. If your pup starts acting different than usual and lethargic, you need to cool her down and watch her closely to know whether or not a vet visit is required.
I also wanted to mention that whenever I take my chi for walks, like when we're camping, I always walk bare-footed with her. If the concrete (sidewalk) is too hot for my feet, I know that it's definitely too hot for Midgies. I know that sounds weird, but I've always done that, not to mention I hate shoes. Lol
