Abstract

A cooling component for an automobile has a case and a cover. A direction along a central axis is a first direction, and a direction perpendicular to the central axis is a second direction. One of a case weld portion and a cover weld portion is referred to as a first weld portion, and the other thereof is referred to as a second weld portion. At this time, an inclined surface, which is inclined from the inward side to the outward side in the second direction away from the second weld portion, is formed at a tip end of the first weld portion in the first direction. A flat surface intersecting with the first direction is formed at a tip end of the second weld portion in the first direction. The first weld portion and the second weld portion are joined to each other by welding.

First claim

What is claimed is:

1 . A cooling component for an automobile, comprising:
a case that has a case opening at an end portion in a first direction along a central axis, accommodates components of a pump on an inward side in a second direction perpendicular to the central axis, and has a case weld portion along a peripheral edge of the case opening; and a cover that is disposed side by side with a side of the case in the first direction, has a cover opening facing the case opening, and has a cover weld portion along a peripheral edge of the cover opening, wherein, when one of the case weld portion and the cover weld portion is referred to as a first weld portion, and the other thereof is referred to as a second weld portion, an inclined surface, which is inclined from an inward side to an outward side in the second direction away from the second weld portion, is formed at a tip end of the first weld portion in the first direction, a flat surface intersecting with the first direction is formed at a tip end of the second weld portion in the first direction, and the first weld portion and the second weld portion are joined to each other by welding.

2 . The cooling component for an automobile according to claim 1 , wherein a volume of an outer weld burr that extends to an outward side in the second direction from a weld layer between the first weld portion and the second weld portion is smaller than a volume of an inner weld burr that extends to an inward side in the second direction from the weld layer.

3 . The cooling component for an automobile according to claim 1 , further comprising:
an inner standing wall that is disposed away from the first weld portion and the second weld portion to an inward side in the second direction; and an outer standing wall that is disposed away from the first weld portion and the second weld portion to an outward side in the second direction.

4 . A method for manufacturing a cooling component for an automobile,
wherein, in a pump which includes: a case that has a case opening at an end portion in a first direction along a central axis, accommodates components of the pump on an inward side in a second direction perpendicular to the central axis, and has a case weld portion along a peripheral edge of the case opening; and a cover that is disposed side by side with a side of the case in the first direction, has a cover opening facing the case opening, and has a cover weld portion along a peripheral edge of the cover opening, when one of the case weld portion and the cover weld portion is referred to as a first weld portion, and the other thereof is referred to as a second weld portion, an inclined surface, which is inclined from an inward side to an outward side in the second direction away from the second weld portion, is formed at a tip end of the first weld portion in the first direction, a flat surface intersecting with the first direction is formed at a tip end of the second weld portion in the first direction, and the first weld portion and the second weld portion are joined to each other by welding.

5 . The method for manufacturing a cooling component for an automobile according to claim 4 , wherein a flat surface intersecting with the first direction is formed on an inward side of the inclined surface in the second direction at a tip end of the first weld portion in the first direction, and the first weld portion and the second weld portion are joined to each other by welding.

6 . The method for manufacturing a cooling component for an automobile according to claim 4 , wherein, when a region of the first weld portion which is melted by the welding is referred to as a melt region, a height of the inclined surface in the first direction is smaller than a height of the melt region in the first direction.

7 . The method for manufacturing a cooling component for an automobile according to claim 4 , wherein a width of the second weld portion in the second direction is larger than a width of the first weld portion in the second direction.
