Abstract

A header tank for a heat exchanger for supplying a heat exchange fluid to a core unit in which a plurality of tubes are provided side by side includes an inlet part for introducing the heat exchange fluid into the header tank, and a plurality of ribs projecting into the header tank, extending in directions intersecting with a central axis direction of the inlet part, arranged side by side in the central axis direction and configured to cause the heat exchange fluid to flow into the tubes. The plurality of ribs project more into the header tank with increasing distance from the inlet part.

First claim

The invention claimed is:

1. A header tank for a heat exchanger for supplying a heat exchange fluid to a core unit in which a plurality of tubes are provided side by side, comprising:
an inlet part arranged to introduce the heat exchange fluid into the header tank; and
a plurality of pairs of ribs projecting into the header tank, extending from left and right inner walls to an opening of a tube side in directions intersecting with a central axis direction of the inlet part, arranged side by side in the central axis direction and configured to cause the heat exchange fluid to flow into the tubes;
wherein the plurality of pairs of ribs project more into the header tank as a distance of the ribs from the inlet part increases.

2. The header tank for the heat exchanger according to claim 1 , wherein:
the plurality of pairs of ribs project toward the tubes.

3. The header tank for the heat exchanger according to claim 1 , wherein:
a distance between the ribs and a plane including a central axis of the inlet part and passing through a center of the header tank increases as the distance of the ribs from the inlet part decreases.

4. The header tank for the heat exchanger according to claim 1 , wherein:
the plurality of tubes are provided side by side in a direction intersecting with a central axis of the inlet part; and
the plurality of pairs of ribs cause the heat exchange fluid to flow into the tubes located at outer sides as the distance of the ribs from the inlet part increases.

5. The header tank for the heat exchanger according to claim 4 , wherein:
the pairs of ribs respectively include a projection projecting from the header tank toward the inlet part.
