摘要

An energy absorber has at least one hollow core post filled with coolant, two supporting boards, multiple first material layers and second material layers. The supporting boards are mounted respectively on two ends of the at least one hollow core post. The first material layers and second material layers are alternately mounted between the supporting boards. Accordingly, the operation temperature of the energy absorber can be prevented from increasing by the coolant in the core post.
