Abstract

An in-vehicle cooling device includes: a header to be mounted so as to be adjacent to a side surface of a transformer mounted on a back side of a bottom portion of a vehicle, the header having a vertical surface along a traveling direction and a direction orthogonal to the travelling direction; a vertical-direction installed cooling pipe having both ends fixed to the header and being installed on a vertical plane orthogonal to the traveling direction; and a traveling-direction installed cooling pipe having both ends fixed to the header and being installed on a travel plane that is parallel to a horizontal plane, the vertical-direction installed cooling pipe and the traveling-direction installed cooling pipe being installed to overlap with each other in a direction orthogonal to the header.

First claim

The invention claimed is:

1. An in-vehicle cooling device, comprising:
a header to be mounted so as to be adjacent to a side surface of a transformer mounted on a back side of a bottom portion of the vehicle, the header having a surface extending along a traveling direction that is a horizontal direction along which air flows during traveling of the vehicle and a direction orthogonal to the travelling direction;
a vertical-direction installed cooling pipe having
both ends each fixed to the header at different heights of positions of the header in a vertical direction, and
a part between the both ends of the vertical-direction installed cooling pipe that is orthogonal to the traveling direction,

the vertical-direction installed cooling pipe being installed on a vertical plane in the vertical direction that is a direction along which the air flows from a lower side to an upper side during a stop of the vehicle; and
a traveling-direction installed cooling pipe having
both ends each fixed to the header at different positions in the traveling direction, and
a part between the both ends of the traveling-direction installed cooling pipe that is installed on a travel plane parallel to a horizontal plane,

the vertical-direction installed cooling pipe and the traveling-direction installed cooling pipe being installed to overlap with each other in a direction orthogonal to the header,
the traveling-direction installed cooling pipe having a part that is not hidden by the vertical-direction installed cooling pipe when viewed from above in the vertical direction, and
an opening in the header corresponding to the traveling-direction installed cooling pipe is aligned with an opening in the header corresponding to the vertical-direction installed cooling pipe in the vertical plane.

2. The in-vehicle cooling device of claim 1 ,
wherein the vertical-direction installed cooling pipe and the traveling-direction installed cooling pipe form a cooling pipe group, and
wherein the traveling-direction installed cooling pipe is installed on an outermost side of the cooling pipe group.

3. The in-vehicle cooling device of claim 1 ,
wherein the vertical-direction installed cooling pipe and the traveling-direction installed cooling pipe form a cooling pipe group, and
wherein the vertical-direction installed cooling pipe is installed on an outermost side of the cooling pipe group.

4. The in-vehicle cooling device of claim 1 ,
wherein the traveling-direction installed cooling pipe includes a plurality of the traveling-direction installed cooling pipes or the vertical-direction installed cooling pipe includes a plurality of the vertical-direction installed cooling pipes, and
wherein the plurality of the traveling-direction installed cooling pipes or the plurality of the vertical-direction installed cooling pipes have a same shape.

5. The in-vehicle cooling device of claim 1 , wherein at least one of the traveling-direction installed cooling pipe and the vertical-direction installed cooling pipe comprises a linear part.

6. The in-vehicle cooling device of claim 1 ,
wherein a plurality of the traveling-direction installed cooling pipes are arranged on the same travel plane,
wherein, on an inner side of the traveling-direction installed cooling pipe having a shortest total length among the traveling-direction installed cooling pipes present on the same travel plane, the vertical-direction installed cooling pipe is installed in one or more rows.

7. The in-vehicle cooling device of claim 1 ,
wherein a plurality of the vertical-direction installed cooling pipes are arranged on the same vertical plane,
wherein, on an inner side of the vertical-direction installed cooling pipe having a shortest total length among the vertical-direction installed cooling pipes present on the same vertical plane, the traveling-direction installed cooling pipe is installed in one or more rows.

8. The in-vehicle cooling device of claim 1 ,
wherein a plurality of the traveling-direction installed cooling pipes are arranged on the same travel plane,
wherein the plurality of the traveling-direction installed cooling pipes are arranged in a nested shape in which each of the plurality of the travelling-direction installed cooling pipes has a length larger than a length of another one, disposed on a more inner side, of the travelling-direction installed cooling pipes, and
wherein the vertical-direction installed cooling pipe is installed in an orthogonal manner between the plurality of the traveling-direction installed cooling pipes in the nested shape.

9. The in-vehicle cooling device of claim 1 ,
wherein a plurality of the vertical-direction installed cooling pipes are arranged on the same vertical plane,
wherein the plurality of the vertical-direction installed cooling pipes are arranged in a nested shape in which each of the plurality of the vertical-direction cooling pipes has a length larger than, a length of another one, disposed on a more inner side, of the vertical-direction cooling pipes, and
wherein the traveling-direction installed cooling pipe is installed in an orthogonal manner between the plurality of the vertical-direction installed cooling pipes in the nested shape.
