The present invention is to provide a heat sink withheat pipe, which is limited in height, not so noisy, compact and highly efficient in radiation, and can lower the temperature inside a casing as a whole more effectively even when it is used in an electronic appliance limited in height such as a personal computer, a game machine or the like. Each set of data consists of two vectors, which constitute the operands for a permute instruction. The system of modularized components allows flexibility in seating use and design.
