- the upper plate 30 is in contact with the power semiconductor device 15 disposed on the upper plate
- the lower plate 40 is in contact with the power semiconductor device 15 disposed on the bottom.
- the upper plate 30 is mainly responsible for cooling the power semiconductor device 15 adjacent to the top
- the lower plate 40 is mainly responsible for cooling the power semiconductor device 15 adjacent to the bottom. That is, since the portion responsible for cooling the upper power semiconductor device 15 and the lower plate 40 for cooling the power semiconductor device 15 is divided, the cooling effect is greater than that of the heat sink having a single plate.
- the power semiconductor device 15 has a cooling structure in which a water cooling type and an air cooling type are combined because heat is radiated by the ventilation layer 49 in addition to being in contact with the cooling plates 30 and 40 on which the cooling water flow path to be described later is formed.

That is, in the cooling plates 30 and 40, a water channel is an empty space through which the cooling water can flow, and in the present invention, the water channel is formed in the form of a plate-shaped water tank. That is, as shown in FIG. 5 , the water tanks 31 and 41 may have a rectangular cross-section.
- the upper plate 30 has a 'U'-shaped upper cooling water flow path 32 (or a first flow path) extending from the inlet 22 to the outlet 24 .
- the upper cooling water flow path 32 is formed in a plate shape along the upper plate 30 .
- the upper cooling water flow path 32 is formed in a wide plate shape to increase the flow rate per unit area. Accordingly, the cooling effect is increased. That is, since the cross-sectional area of the upper cooling water flow path 32 or the upper water tank 31 corresponds to 'A', the flow rate per unit area is increased compared to a heat sink having a tubular cooling water flow path. In other words, the proportion of the cooling water flow path per unit area in the heat sink increases, thereby increasing the cooling effect. (See Fig. 5)
- the aspect ratio of the cross-sectional area 'A' of the upper cooling water passage 32 or the upper water passage 31 is preferably set to, for example, 3:1, 5:1, 10:1 or more. This is to increase the cooling effect by making the horizontal length sufficiently larger than the vertical length to form a plate-shaped flow path.

Accordingly, the upper cooling water flow path 32 is disposed closer to the power semiconductor device 15 in contact with the upper surface of the upper plate 30 . (See FIG. 6 ) (In the lower plate 40 , which is formed symmetrically with the upper plate 30 , the lower coolant flow path 42 is biased toward the lower side from the lower plate 40 .
- the lower plate 40 In , the lower portion 40b of the lower coolant flow passage 42 is thinner than the upper portion 40a of the lower coolant passage 42 . Accordingly, closer to the power semiconductor device 15 in contact with the lower surface of the lower plate 40 . Since the cooling water passages 32 and 42 are disposed close to the adjacent power semiconductor devices 15, respectively, the cooling effect is increased.
- the upper plate 30 has a partition wall portion 34 formed in the middle portion along the longitudinal direction.
- the partition wall 34 separates the inlet 22 side and the water outlet 24 side.
- the bulkhead portion 34 extends to the distal end at the front of the upper plate 30 with the inlet 22 and the outlet 24 , and extends to the rear of the upper plate 30 to a point spaced apart from the distal end by a predetermined distance.

- the upper cooling water flow path 32 is divided into an inlet side flow path 32a, a connecting part flow path 32b, and an outlet side flow path 32c. Cooling water flows into the water inlet 22, passes through the water inlet pipe 25, the inlet side flow path 32a, the connecting part flow path 32b, the water outlet side flow path 32c, and the water outlet branch pipe 26, and exits to the water outlet 24. comes out

- the collision pillar 36 extends from the upper surface 30a to the lower surface 30b of the upper water tank 31 constituting the upper cooling water flow path 32 . (See Fig. 5)
- the collision pillar 36 not only serves to transfer heat from the upper surface 30a to the lower surface 30b of the upper plate 30, but also collides with the cooling water as it flows to create a vortex and mix with the heat dissipation (heat mixing) function. also do
- the collision pillars 36 are arranged to gradually become denser along the cooling water flow path. Simply divided, "density of the collision pillars 36 of the inlet-side flow path 32a ⁇ density of the collision pillars 36 of the connection flow path 32b ⁇ density of the collision pillars 36 of the outlet-side flow path 32c" and composed together Referring to FIG. 7 , this configuration is clearly shown. (Here, density means the number of units arranged per unit area.)
- the density of the collision pillars 36 of the second half is higher than the density of the collision pillars 36 of the first half.
- the density of the collision pillars 36 in the first half is higher than the density of the collision pillars 36 in the second half.
- the density of the collision pillar part 36 is relatively low, so that the cooling water enters speed quickly, and the water outlet side flow path 32c.
- the density of the collision pillar part 36 is relatively high, so that thermal mixing of the cooling water occurs well.
- the collision pillars 36 are arranged in a staggered form. That is, the n-th column and the n-1 th column are arranged to cross each other when viewed from the front or the top. This is to increase the chance that the coolant collides with the collision pillar 36 so that mixing occurs well.
- the collision pillars (36) are not arranged alternately, so that they are arranged singly. This is in order not to reduce the inflow speed of the cooling water.
- a non-collision zone (32d) in which the collision pillar part (36) is not arranged is provided in the middle part of the inlet side flow path (32a) or the water outlet side flow path (32c). This is to prevent stagnation by changing the cooling water flow speed and to reinforce the speed at which the collision pillar 36 enters the densest area. This is also effective when a plurality of semiconductor devices coupled to the upper or lower surfaces of the heat sink are configured.
- FIG. 9 shows the flow velocity distribution in the cooling water passage. It is shown that the cooling water enters rapidly in the inlet flow path 32a, and mixed flow occurs in the second half, rotation occurs in the connecting part flow path 32b, and various types of mixed flow occur in the outlet side flow path 32c. .
- the coolant shows a streamline of the coolant.
- the coolant flows along the upper coolant flow path 32 , it collides with the collision pillar 36 and exhibits an 'S'-shaped tortuous flow. That is, the time for contact with the cooling plate increases as it flows in a meandering form rather than having a simple straight flow, and there are many opportunities for vortex to occur, so that the cooling water is well mixed with heat.
- a support portion 38 is formed to protrude from the side surface of the upper plate 30 .
- a fastening hole 39 is formed in the support part 38 and may be fixed by a fastening member or the like.

- the connection supports 37 and 47 not only support the upper plate 30 and the lower plate 40 , but also serve as a heat exchange passage between the upper plate 30 and the lower plate 40 .
- Through-holes 35 and 45 are formed in the connection supports 37 and 47 to allow air to flow therethrough.
- the cooling water flow path is formed in a plate shape to increase the space occupied per unit area. That is, compared to the prior art in which the cooling water flow path is formed in a planar shape and is linearly formed, the flow rate of the cooling water formed in a unit volume is increased.
