You'd be concentrating all the waste heat in one place underground.
You could suck in air through 130-160 feet of underground sewer piping.
6" down, seams to be waterproofed, end to be closed to insects and other critters.
That's what they do when installing active ventilation systems over here.
Normally, it goes over a highly efficient heat-exchanger as it's used even in winter (the ground @ 6' under usually being warmer than the outside air), but for summer use, you could do without the heat exchanger.
