Patent ID: 7359195

Claim:
A heatsink comprising: a plurality of heat-dissipating plates stacked on one another, each heat dissipating plate including a heat-absorbing region that has a lower end for contacting a heat source to absorb heat from the heat source, a long heat-dissipating region extending from a first side of the heat-absorbing region and a short heat-dissipating region extending from a second side of the heat-absorbing region, the long and short heat-dissipating regions for transferring heat from the heat-absorbing region and outwardly dissipating the heat, wherein the heat-absorbing regions are joined to one another and the long and short heat-dissipating regions are spread out from the heat-absorbing regions, wherein the length of each of the long heat-dissipating regions extending from the first side of the heat-absorbing regions is greater than the length of each of the short heat-dissipating regions extending from the second side of the heat-absorbing regions to define an asymmetric shape as a whole when the heatsink is installed to the heat source for cooling.
