Wait... I was born after the 90s and got my first Car a year ago. It still has a Detachable Radio, No Automatic Windows and also ... is the last pic a trick against heat if you have no AC? Because I also have no AC and I always fucking die when I enter my Car after Work when the sun was blasting on it for some time. Are you telling me that I can just place that thing that is normally against ice in Winter in there and my Car stops overheating? I must be misunderstanding. This cant be so easy right?
Wait, your telling me I can just place that thing that normally stops your Car from overheating and it helps against ice in the Winter?
I always thought that's its only use case
I have never known this was also for ice and now I must try. Thank you!
It’s not. It’s designed to be inside as a sun reflector. People just use them to block ice formation too but they won’t last as long that way. They weren’t designed to be rained/snowed on and frozen…but they aren’t expensive so does it really matter?
I think it stops ice forming by still being inside, by reflecting light and heating up the windshield, but I could be mistaken.
Thats the main usecase lol
It's a pop out windshield shade, yes. Put it in your windshield when you get out and it'll block the sun and keep your car cooler. They're incredibly common, can find a dozen options at any Target, Walmart, etc.
Is this any different to the thing I put outside my Windshield in winter? Or can I just use that?
It's the same if it has this silvery surface which reflects radiation. Also don't expect miracles. If you park in the sun, the air inside will still be super hot. The actual advantage is that your dash, steering wheel and seats won't be lava when you get in the car.
Ah sad... because I looked all around my Workplace. There is not one single parking spot in the shadow... So my car will still be burning... I was exited here for a second.
The other guy isn't technically wrong. But I know from experience that while your car will be warm on the inside, using the shade will mean the difference between unbearably hot and warm.
Just park so that your car points mostly towards the sun so that the windshield has the most direct sunlight and put up the shade.
The reason it works is because the sun gives off IR radiation (in addition to visible light and UV). Glass traps heat when given by IR. The IR passes through the glass, hits the interior surface, then gets converted to physical heat. Which is then trapped by the physical barrier of the window. The cover reflects most of the IR back into the sky. So the car mostly warms up from heat absorbed by the ambient air temperature, instead of being blasted by direct sunlight.
Exactly right. I just meant that it definitely still will be uncomfortably warm when you get in at first, but overall hear will be lower. So definitely use it!
Preventing the interior from being hit by direct sunlight also has the huge advantage the once you let out the warm air, there are no superheated parts that continue to radiate heat for many more minutes, making the actual ride much more enjoyable as well.
You can use the same Windshield in winter and summer (I did many years). When it is used from outside, it helps even more against the temperature.
It is a bit more fun though, to use one with big eyes to be positioned inside and make your car look like from Cars movie. Example on Pinterest
We have the red version (strangely ours was much cheaper here in Germany than what I just found on Wallmart website) in our little red Toyota and aside from keeping the car cooler it is looking really cute.
I'm also from Germany :) You can see that from the Server I'm on. Tchncs.de
It is a small world in the Fediverse :)
yes you can use that, and to be most effective you also obviously put it outside
Thanks
I hate to break it to you but your car is a piece of shit
It's not lol It works perfect, it just has no AC or Automatic Windows or anything because this is an old car. Pretty normal for the first car.
One man's trash is another man's treasure.
Your car would be incredibly easy to work on too which is great for saving money if you're willing to do the work yourself.
I don't know anything about cars, but my Brother is a Car Mechanic, so yea. :)
That thing does indeed keep the car cooler.
These are tricks no one tells you anymore today because everyone has AC. I will try this Monday. You guys saved my life.
It helps but it’ll still be hot as crap inside. You just won’t need your oven mitts to grab the wheel.
