Thus, it is obvious that the peripheral edge of the integral heat dissipation plate 31 forms a retaining wall, so that the cooling liquid is not easily removed from the heat dissipation plate 31. The periphery leaked out. As shown in the fourth figure, each of the heat dissipation plates 31 has a plurality of first spacers 311 and a plurality of second spacers 312 intersecting with the first spacers 311; in particular, the second figure shows the first spacer The strip 311 and the second strip 31 2 intersect perpendicularly to each other, which is a preferred embodiment.

Referring to the first figure together, the cooling liquid flows from the inlet pipe 21 (not shown) into the water inlet passage 316 and successively passes through the first closed openings 313 and 313 of each of the heat dissipation plates 31, 31', due to the adjacent upper side, The lower layers of the heat dissipation plates 31, 31' are misaligned, so that the liquid will pass through the adjacent upper and lower two-layer heat dissipation plates 31, 31, and the form number A0101 between the first page and the third page is 100 pages. After 11 days, the page gap is being replaced and is blocked by the first spacer Μ or 311 of each layer of the heat dissipation plates 31, 31, and is moved to the upper, lower, left and right directions in each of the four layers of heat dissipation plates 31, 31'. The through holes 315, 315 are formed in the plurality of microchannels, and finally the second closed openings 314 and 314' of each of the heat dissipation plates 31, 31' are merged into the water outlet opening channel 317 to exit the water outlet pipe 22 ( Not shown) 'But since the cross-sectional direction of the ninth diagram is perpendicular to the inlet opening flow path 3 6 And the connection line of the outlet opening flow path 31 7 , the notches 313 and 314 , the inlet opening flow path 316 and the outlet opening flow path 317 cannot be displayed in the ninth diagram. [0020] In order to facilitate understanding of the stereoscopic flow effect of the cooling liquid in the entire heat sink 3, referring to the top view of the tenth figure, from the structure of the entire heat exchanger 3, the through hole of the upper heat sink 31 The intersection of the first spacer 311 and the second spacer 312 of the lower heat dissipation plate 31 is divided into a plurality of micro flow passages, so that the liquid will flow into the through hole 31 5 and be subjected to the lower heat dissipation plate 31. A spacer 311 and a second spacer 312' are blocked to flow in four directions of up, down, left, and right, and so on, so that the contact area between the cooling liquid and the heat dissipation plates 31, 3Γ is greatly increased. The contact time' thus improves the overall heat dissipation. [0021] Referring to the eleventh to fourteenth drawings, a second embodiment of the present invention is shown. Similar to the first embodiment, the base 10 has a circular plate shape, and the cover body 2 has a middle cover body.

A first closed opening 31 3a and a second closed opening 314a are respectively defined in the positions of 22 . Similarly, a pad 11 is provided at the joint between the base 10 and the cover 20 to prevent leakage of liquid. [0022] The difference between the second embodiment and the first embodiment is mainly that the first embodiment has the first spacer 311 and the second spacer 312' intersecting the first spacer 311 but in the second embodiment Each of the heat dissipation plates 31a has only a plurality of spacers 311a' and the spacers 31a are arranged at an oblique angle with respect to the connection lines of the first closed opening 313a and the second closed opening 314a, and the adjacent two spacers 311a A through hole 315, a is provided between the openings.

Because the adjacent upper and lower layers of the heat dissipation plates 31a, 3a, are misaligned between each other, the liquid will pass through the gap between the adjacent upper and lower two-layer heat dissipation plates 313, 31a' and is dissipated by each layer. The spacers 311a or 311a' of the plates 31a, 31a are blocked and flow through the through holes 315a, 315a between the heat dissipation plates 31a, 31a in the upper, lower, left and right directions. In the plurality of microchannels, finally, the second closed openings 314a and 314a' of each of the heat dissipation plates 313, 31a merge into the water outlet opening 317a and exit the water outlet pipe 22 (not shown): thereby greatly increasing the cooling liquid and The contact area and contact time between the heat dissipation plates 31a, 31a are thus improved Cooling effect thereof.
