Therefore, definitions of these terms should be made based on the contents throughout this specification.

Fig. 1 is a perspective view schematically showing a coil cooling apparatus according to an embodiment of the present invention, Fig. 2 is a front sectional view schematically showing a coil cooling apparatus according to an embodiment of the present invention, Fig. 3 is a cross- Quot; A ".

1 to 3, a coil cooling apparatus according to an embodiment of the present invention includes a base 10, an inner cover portion 20, a cooling water supply portion 30, and a heat dissipation portion 40.

The base 10 is formed on the bottom where the coils 5 are mounted. A plurality of coils 5 of three to four stages are stacked on the base 10. The base 10 has a flat shape. In the embodiment of the present invention, the base 10 is made of a disc or a rectangular plate.

The inner cover portion 20 is provided on the upper portion of the base 10 and covers the coil 5. The inner cover portion 20 is opened at its lower portion and a receiving space is formed therein so as to accommodate the coil 5 therein. Here, the accommodating space of the inner cover portion 20 is formed larger than the size of the coil 5 accommodated therein. Between the coils 5 of the inner cover portion 20, there is a space through which air can flow.

The cooling water supply unit 30 supplies cooling water W to the outside of the inner cover unit 20. [ The cooling water supply unit 30 receives the cooling water W from the outside and ejects the cooling water W on the surface of the inner cover unit 20 through a nozzle or the like in a spraying manner. At least one cooling water supply unit 30 is provided on the upper portion of the inner cover unit 20 so as to supply cooling water W from the upper portion to the lower portion of the inner cover unit 20. [ The cooling water W supplied from the cooling water supply part 30 and flowing downward from the upper part of the inner cover part 20 cools the surface of the inner cover part 20 while flowing along the outer peripheral surface of the inner cover part 20.

The coil 5 accommodated in the inner cover portion 20 is also indirectly cooled by the inner cover portion 20 when the surface of the inner cover portion 20 is cooled by the cooling water supply portion 30. [

The heat dissipating unit 40 is installed to spirally surround the outer peripheral surface of the inner cover unit 20 in an oblique direction from the top to the bottom. The heat radiating portion 40 protrudes from the outer circumferential surface of the inner cover portion 20 so that the cooling water W injected from the cooling water supply portion 30 flows downward from the upper portion along the heat radiating portion 40 to the inner cover portion 20 ) Can be uniformly cooled.

The inclination angle of the slanting line formed in the inner cover portion 20 of the heat radiating portion 40 can be determined in consideration of the supply amount of the cooling water W and the time during which the cooling water W remains in the heat radiating portion 40.

In the embodiment of the present invention, the heat dissipating unit 40 may be formed in a top-down step shape to increase the travel distance of the cooling water W supplied from the cooling water supply unit 30 and to delay the down time. The cooling water W supplied from the cooling water supply unit 30 flows down along the downward stepped heat dissipation unit 40 and the length and time of staying in the heat dissipation unit 40 increases to contact the outer peripheral surface of the inner cover unit 20 Time is increased. Therefore, the time during which the cooling water W descending downward along the step-like heat dissipating unit 40 is left in the inner cover unit 20 is increased, so that the entire inner cover unit 20 can be uniformly cooled, The cooling of the coil 5 accommodated in the inner cover portion 20 can be made uniform.

A plurality of holes 43 through which the cooling water W flows downward are formed in the heat dissipating unit 40. The holes 43 allow the cooling water W flowing along the heat dissipating unit 40 to descend to the other heat dissipating unit 40 provided at the lower part. Accordingly, a part of the cooling water W spirally descends along the heat dissipating unit 40, and another part of the cooling water W comes down along the hole 43 formed in the heat dissipating unit 40.

In the embodiment of the present invention, the holes 43 are formed to be shifted from each other in the heat radiation portion 40 adjacent in the vertical direction. When the holes 43 are formed at the same position in the vertical direction of the heat dissipating unit 40, the cooling water W does not flow along the heat dissipating unit 40 but goes down in the vertical direction, In order to prevent the deterioration of efficiency. The holes 43 are formed to be offset from each other in the vertical direction in the adjacent heat dissipating unit 40. When the cooling water W is excessively supplied to the heat dissipating unit 40, 40, the surface of the inner cover portion 20 can be uniformly cooled.

One end of the heat dissipating portion 40 is fixed to the inner cover portion 20, and the other end portion is formed to be inclined upward. The heat dissipating unit 40 is provided on the inner cover unit 20 so as to be inclined so that the cooling water W falling along the heat dissipating unit 40 can be prevented from falling outwardly of the heat dissipating unit 40.

FIG. 4 is a front sectional view schematically showing a coil cooling apparatus according to another embodiment of the present invention, and FIG. 5 is a partial enlarged view schematically showing "B" of FIG.

4 and 5, protrusions 45 protrude upward from the edges of the heat dissipating unit 40. As shown in FIG. The protruding portion 45 is annularly protruded along the edge of the heat dissipating portion 40. The projecting portion 45 is protruded upward from the edge of the heat dissipating portion 40 to receive a certain amount of the cooling water W that is excessively supplied from the cooling water supplying portion 30 and prevent the cooling water W from dropping outwardly of the heat dissipating portion 40 . The projecting height of the projecting portion 45 can be determined according to the capacity of the cooling water W flowing on the heat dissipating portion 40.

6 is an operational diagram that schematically illustrates a coil cooling apparatus according to another embodiment of the present invention.

Referring to FIG. 6, a plurality of partition walls 47 protrude upward from the heat dissipation unit 40. The partition wall 47 delays the flow of cooling water W flowing down on the heat dissipating unit 40. The cooling water W hits the partition wall 47, and the flow is changed to delay the time taken for the cooling water W to flow down from the heat dissipating unit 40. The time for which the cooling water W remains on the heat radiating portion 40 is increased by the partition 47 and the time for staying on the surface of the inner cover portion 20 is increased to cool the inner cover portion 20 Time is increased.

Further, the partition 47 is formed in a zigzag shape on the heat dissipating portion 40, so that the flow of the cooling water W can be delayed. The flow time of the cooling water W may be changed according to the size and shape of the partition 47. The partition wall 47 may be formed in a polygonal columnar shape and may be curved to induce the flow of the cooling water W. The partition wall 47 may be formed as a honeycomb-shaped hexagonal column so as to protrude from the heat-radiating portion 45. The cooling water W can be flowed or changed in direction at the tip end of the honeycomb partition wall 47.

In the present invention, the heat dissipating unit 40 and the inner cover unit 20 are made of stainless steel in order to prevent corrosion by the cooling water W.

The coil cooling apparatus according to the present invention further includes an outer cover portion (50). The outer cover part 50 is provided to be spaced apart from the inner cover part 20, and a cooling water supply part 30 is installed on one side of the upper part. The outer cover portion 50 is formed to have a size capable of accommodating the entire inner cover portion 20. At least one cooling water supply part (30) is provided in the outer cover part (50). In the embodiment of the present invention, the cooling water supply portion 30 may be installed symmetrically on the upper portion of the outer cover portion 50. A discharge hole (not shown) may be formed in the lower portion of the outer cover portion 50 to discharge the cooling water W downward along the heat dissipating portion 40 to the outside.

The cooling water W is cooled down along the heat dissipating portion 40 through the cooling water supply portion 30 provided on the upper portion of the outer cover portion 50 so that the inner cover portion 20 is cooled and the coil 5 is indirectly heated And cooled.

Next, the operation of the coil cooling apparatus according to the present invention will be described.

The coil 5 is stacked on the base 10 at multiple stages and the inner cover portion 20 covers the entire coil 5. [ At this time, the cooling water (W) is sprayed from the cooling water supply part (30) provided on the outer cover part (50) toward the upper part of the inner cover part (20).

The cooling water W injected from the cooling water supply part 30 flows downward from the upper part to the inner cover part 20 along the heat radiating part 40 provided in a spiral shape in an oblique direction to the inner cover part 20. At this time, the cooling water W is cooled along the helical heat dissipating unit 40 to cool the surface of the inner cover unit 20 uniformly.

A part of the cooling water W is spirally descended along the heat dissipating part 40 to cool the inner cover part 20 and the other part of the cooling water W is discharged through the hole 43 formed in the heat dissipating part 40 And then down along the helical heat dissipating portion 40 or down through the hole 43. [0051]

At this time, the heat dissipating unit 40 is formed to be inclined to the inner cover unit 20, so that the cooling water W is prevented from falling outwardly of the heat dissipating unit 40 without cooling the inner cover unit 20. [ The cooling water W is prevented from dropping outwardly toward the heat dissipating unit 40 by the protruding portion 45 formed annularly protruding from the edge of the heat dissipating unit 40.

The cooling water W is delayed in flow by the plurality of partition walls 47 protruding from the radiator 40 while descending along the radiating portion 40 and the time remaining on the surface of the inner cover portion 20 is increased . Further, the cooling water W can uniformly cool the inner cover portion 20 while the flow direction and time are delayed by the partition wall 47 formed in a zigzag shape or the like.

As described above, the coil cooling apparatus according to the present invention has a structure in which the heat dissipation unit 40 is provided in the inner cover unit 20 so that the cooling water W flows down along the heat dissipation unit 40 while moving the inner cover unit 20 It is possible to reduce the temperature deviation of the inner cover portion 20 for each position.

According to the present invention, the cooling water W uniformly cools the inner cover portion 20 by the heat dissipating portion 40 so that the coils 5 accommodated in the inner cover portion 20 are uniformly cooled, It is possible to prevent the occurrence of mechanical deformation.

According to the present invention, the consumption amount of the cooling water (W) required for uniform cooling of the coil (5) is reduced, so that the production cost can be reduced.
