US Patent 7447024 Heat sink for a memory

A heat sink for a memory comprises two heat-conducting sheets and a fan. Both sides of the memory are clamped by the two heat-conducting sheets, and between the two heat-conducting sheets is defined a convective space. The upper end of the convective space is sealed. The fan is disposed between the two heat-conducting sheets, so that the fan can guide the air into the convective space from exterior to exchange heat with the memory and the two heat-conducting sheets, and then the air will carry away the heat into the environment, so as to achieve the heat dissipating effect.
