The ceiling also comprises a rear surface opposites to the front surface and comprises rear convex parts and rear concave parts corresponded to the front concave parts and the front convex parts respectively. The upper cavity opposites to the rear surface and separated to the rear convex parts to define a first flow channel. The protrusions are disposed in the rear concave parts and separated to a side wall and a bottom wall of the rear concave parts to define a second flow channel which is connected to the first flow channel to introduce a cooling fluid.
