Abstract

A self-cooled reactor apparatus includes: a pair of frames attached to a vehicular mount, a coil disposed between the pair of frames and fixed to the frames, a cover disposed between the pair of frames, and a protective member. The coil is covered by the cover having at least a portion thereof in which through-holes are formed. The protective member, while retaining a flow passage for air from the through-holes to the coil, blocks a space between the through-hole and the coil in a penetration direction of the through-holes.

First claim

The invention claimed is:

1. A self-cooled reactor apparatus comprising:
a pair of opposed frames to attach to a vehicle;
a coil fixed to the frames and disposed between the pair of frames;
a cover disposed between the pair of frames to cover the coil, the cover having through-holes formed in at least a portion thereof; and
a protective member to, while retaining a flow passage for air from the through-holes to the coil, block a space between the through-holes and the coil in a penetration direction of the through-holes;
wherein the protective member is at least a pair of members extending so as to approach one another from an air-intake surface in a travel direction of the vehicle, the air-intake surface being a surface of the cover positioned opposite to the vehicle relative to the coil.

2. The self-cooled reactor apparatus according to claim 1 , wherein
the through-holes are formed in hole-forming portions side-by-side in a direction perpendicular to a travel direction of the vehicle, the hole-forming portions being disposed at both end portions of the air-intake surface in the travel direction of the vehicle, and
the protective member is at least a pair of plate-like members extending so as to approach one another from the both end portions of the air-intake surface in the travel direction of the vehicle.

3. The self-cooled reactor apparatus according to claim 1 , wherein
the through-holes are formed in each of a plurality of hole-forming portions side-by-side in a direction perpendicular to a travel direction of the vehicle, the plurality of hole-forming portions being in an air-intake surface, and
the protective member is disposed at each of the plurality of hole-forming portions and is a pair of plate-like members extending so as to approach one another from both end portions of each of the hole-forming portions in the travel direction of the vehicle.
