A Japanese outlet tested heat relief products for sleeping in a car during summer, using only items under 5,000 yen from Muji and Nitori. On the first night, with a high of 33°C, the cabin temperature dropped from 28.9°C to 25.9°C; on the second, with 37.2°C, it stayed above 30°C. The best results came from a homemade ventilation fan, a Muji clip fan (2,990 yen), and a Nitori cooling pad (3,990 yen). The author advises starting with a pre-cooled cabin and combining multiple devices.
