There should be a cooper pipe between the CPU and cooler like this one[1]. Seriously, WTF? Where is it? 1: https://i0.wp.com/lemmymorgan.com/wp-content/upload

Here's an example teardown: https://guide-images.cdn.ifixit.com/igi/iUejB4OfKlPD4Fex.huge https://guide-images.cdn.ifixit.com/igi/iUejB4OfKlPD4Fex.hug... The heat pipe is the part just above and to the left of the fan.

  That's a different model, there is no heat pipe in the video see https://youtu.be/iiCBYAP_Sgg?t=57 https://youtu.be/iiCBYAP_Sgg?t=57

  The model in the video is this one I think — https://www.ifixit.com/Teardown/MacBook+Air+13-Inch+Retina+2018+Teardown/115201 https://www.ifixit.com/Teardown/MacBook+Air+13-Inch+Retina+2... (Video mentions 2019 model, which is a minor revision based on this)

In a way it's possibly more efficient without the heat pipe - the cooler is directly over the CPU in this design, and can be quite large due to the way it's packaged (though it has to be thin). The downside is it's harder to get decent airflow over the fins. The casing is probably designed to direct the airflow, but I'd have to see all parts together to figure out how this works. EDIT: the lower case appears to have some ducting on it, see this example: https://www.ebay.co.uk/itm/324259489798 https://www.ebay.co.uk/itm/324259489798

  That's a very questionable system. It needs to be completely sealed except for intake to work properly.

    Correct. It needs to be completely sealed. You can't take the back off the laptop and have the cooling system function, the case is part of the cooling ducts. Provides for heat dissipation over broader surfaces. This is normal.
