Air cooling system for power battery pack

The invention discloses an air cooling heat dissipation system for a power battery. The air cooling heat dissipation system comprises a power battery pack and an air adjusting structure; the power battery pack comprises a shell, a ceramic shell, a metal arc-shaped plate, a left shell, a right shell and a bottom plate; the shell is an n-shaped structure, which is composed of a top plate, a left plate and a right plate; the ceramic shell is a vertically transparent ceramic sintered part; four corners of the ceramic shell are each provided with a metal arc-shaped body; two edges of the metal arc-shaped body are clamped on a locating protrusion clamp; a battery core is clamped in the centre of each metal arc-shaped body; the battery core and the four metal arc-shaped plates are in line contact; and a cold air inlet and a hot air outlet are connected with an external circulating wind source through a wind pipe. The thermal expansion coefficient of the ceramic shell is small; the problem that the battery pack is ex
