Storage device backplane with penetrating convection and computer framework

A computer framework comprising:

• a motherboard;
• a storage device group comprising at least one storage device;
• a storage device backplane, electrically connecting between the motherboard and the storage device of the storage device group, and comprising:
• an integration board, having a first surface for electrically connecting the storage device group;
• an operation board, superposed on and electrically connected to a second surface of the integration board, provided that the operation board comprises an electronic heating active element (EHAE) and an airflow hole set around the EHAE;
• and
• a heat dissipation unit, comprising a heat absorb portion and multiple fins set on the heat absorb portion, wherein the heat absorb portion makes a thermal contact with the EHAE, the fins laterally extend to cover the airflow hole, and airflow passages formed between the fins corresponding to the airflow hole;
• and
• at least a fan arranged between the motherboard and the storage device backplane.
