Abstract

A power control apparatus includes a case, a cover attached on the case and a gasket which is attached on a wall of the case below the cover. The gasket includes an intermediate pipe and a seal member which seals between the intermediate pipe and the case. The cover includes a water guide portion extending along the wall of the case. The case includes at least two shielding ribs protruding from the case. The shielding ribs are located below the water guide portion. The shielding ribs include portions located above the seal member to overlap the seal member with respect to a vertical direction. The shielding ribs are located between the water guide portion and the seal member with respect to the vertical direction. Each of the shielding ribs includes an inclined portion in which a one-side portion is located lower than the other-side portion.

Claims (22)

1. A power control apparatus, comprising:

a power control circuit configured to perform power conversion and supply an electric current to a load;

a cooler which has a cooling passage and performs absorbing heat generated by the power control circuit while a cooling fluid flows through the cooling passage;

a case which accommodates the power control circuit and the cooler;

a seal member which seals a gap between a pipe forming a passage communicating with an interior of the cooler and the case through which the pipe is inserted;

a water guide portion forming a wall extending downward from a cover member located at an upper portion of the case; and

a visor-like shielding rib disposed to protrude with respect to the case and to cover a lower side of the water guide portion, wherein

the shielding rib include a portion located above the seal member to overlap the seal member with respect to a vertical direction, and wherein

the shielding rib has an inclined portion in which a one-side portion in a horizontal direction is located lower than the other-side portion.

2. The power control apparatus according to claim 1 , wherein

the one-side portion of the shielding rib is located on one side further than a one-side of the seal member in the horizontal direction.

3. The power control apparatus according to claim 1 , wherein

the shielding rib has a length that covers an entire body of the seal member in the horizontal direction.

4. The power control apparatus according to claim 1 , wherein

the shielding rib includes a first shielding rib located directly below the water guide portion and a second shielding rib located directly below the first shielding rib;

each of the first shielding rib and the second shielding rib has an inclined portion in which a one-side portion in the horizontal direction is located lower than the other-side portion.

5. The power control apparatus according to claim 4 , wherein

at least one of the first shielding rib and the second shielding rib has a one-side portion in the horizontal direction which is located on a one side further than a one-end portion of the seal member in the horizontal direction.

6. The power control apparatus according to claim 4 , wherein

a length in the horizontal direction of the first shielding rib and the second shielding rib is enough to cover an entirety in the horizontal direction of the seal member with respect to a vertical view of the first shielding rib and the second shielding rib from above.

7. The power control apparatus according to claim 1 , wherein

the case is installed in a posture inclined with respect to the vertical direction so that a distal end of the shielding rib is located lower than a proximal end thereof.
