1. A liquid-cooling heat dissipation plate with pin-fins, comprising:
a heat dissipation plate body having a first heat dissipation surface and a second heat dissipation surface that are opposite to each other, wherein the first heat dissipation surface is in contact with a heat source, and the second heat dissipation surface is in contact with a cooling fluid;
a plurality of rhombus-shaped pin-fins, wherein a minimal distance between two adjacent ones of the rhombus-shaped pin-fins is from 0.3 mm to 1.5 mm; and
a plurality of ellipse-shaped pin-fins, wherein a minimal distance between two adjacent ones of the ellipse-shaped pin-fins is from 0.3 mm to 1.5 mm;
wherein the plurality of rhombus-shaped pin-fins and the plurality of ellipse-shaped pin-fins are integrally formed on the second heat dissipation surface;
wherein at least one of the ellipse-shaped pin-fins corresponds in position to a relative low temperature region of the heat source, and at least one of the rhombus-shaped pin-fins corresponds in position to a relative high temperature region of the heat source;
wherein an ellipse-shaped cross-section of each of the ellipse-shaped pin-fins has a major axis and a minor axis that have unequal lengths defined thereon, a rhombus-shaped cross-section of each of the rhombus-shaped pin-fins has two diagonals defined thereon, the major axis and one of the diagonals are both parallel to a flowing direction of the cooling fluid, and the flowing direction of the cooling fluid is a direction from the relative low temperature region corresponding in position to the ellipse-shaped pin-fins toward the relative high temperature region corresponding in position to the rhombus-shaped pin-fins.
