Liquid-cooling heat dissipation plate with unequal height pin-fins and enclosed liquid-cooling cooler having the same

A liquid-cooling heat dissipation plate with unequal height pin-fins, comprising:

• a heat dissipation plate body having a first heat dissipation surface and a second heat dissipation surface that face away from each other, wherein the first heat dissipation surface is configured to be in contact with a plurality of heat sources, and the second heat dissipation surface is configured to be in contact with a cooling fluid;
• a plurality of full-height pin-fins formed at the second heat dissipation surface of the heat dissipation plate body;
• and
• a plurality of non-full-height pin-fins formed at the second heat dissipation surface of the heat dissipation plate body;
• wherein a first heat dissipation region to an Nth heat dissipation region are defined on the heat dissipation plate body along a flowing direction of the cooling fluid, N is an integer greater than or equal to two, and the plurality of heat sources correspond in position to the first heat dissipation region to the Nth heat dissipation region, respectively;
• wherein a ratio of the plurality of full-height pin-fins to pin-fins in a first fifty percent of heat dissipation regions from the first heat dissipation region to the Nth heat dissipation region is less than a ratio of the plurality of full-height pin-fins to pin-fins in a second fifty percent of the heat dissipation regions from the first heat dissipation region to the Nth heat dissipation region.
