Claim 0:
1. A water cooling head assembly comprising:
a main body having a first plate and a second plate, the first plate and the second plate being opposite each other, said main body defming an inlet channel and an outlet channel;
a chamber formed inside said main body and positioned between the first plate and the second plate, said chamber communicating with the inlet channel and the outlet channel such that a cooling water is flowable into said chamber through the inlet channel and is flowable out of said chamber through the outlet channel;
a first fin set arranged in said chamber, said first fin set having a plurality of fins in spaced relation to each other, said first fin set being connected to said first plate and adapted to absorb and guide heat energy of the first plate, the plurality of fins of said first fin set dividing said chamber so as to form a plurality of first channels;
a second fin set arranged in said chamber, said second fin set having a plurality of fins in spaced relation to each other, said second fin set being connected to said first plate and adapted to absorb and guide the heat energy of said first plate, the plurality of fins of said second fin set dividing said chamber so as to form a plurality of second channels, wherein said first fin set is adjacent the inlet channel, said second fin set being positioned between said first fin set and the outlet channel, said chamber forming a communication region between said first fin set and said second fin set, the communication region communicating with the plurality of first channels and the plurality of second channels such that the cooling water flows into said chamber through said inlet channel and flows out of said chamber through the plurality of first channels and the communication region and the plurality of second channels and the outlet channel, wherein a thickness of a fin of said first fin set is larger than a thickness of a fin of said second fin set, wherein a total surface area of the plurality of fins of said first fin set is less than a total surface area of the plurality of fins of said second fin set, wherein a total volume of the plurality of first channels is defmed as ΣV1 and a total volume of the plurality of second channels is defmed as ΣV2, ΣV1 is approximately equal to ΣV2, wherein 0.9·ΣV1<ΣV2<1.1·ΣV1.
