Abstract

A heat exchanger includes multiple tubes, multiple fins, and a partition wall. The multiple fins are stacked alternately with the tubes to form a core including a first section and a second section. The partition wall partitions between the first section and the second section. The first section has multiple drain passages in the vicinity of the partition wall.

First claim

What is claimed is:

1. A heat exchanger comprising:
a plurality of tubes;
a plurality of fins stacked alternately with the tubes to form a core including a first section and a second section; and
a partition wall partitioning between the first section and the second section, wherein
the first section has a plurality of drain passages adjacent to the partition wall,
the drain passages have a width,
the width is greater than a fin pitch of the fins in a lateral direction of the tubes, wherein the fin pitch is a length between two peaks of the fin in the lateral direction,
the partition wall includes a first insert inserted between the first section and the second section,
the first insert is in a comb shape and includes a first base and a plurality of first blades,
the first blades are extended from the first base, and
each of the first blades inserted between two adjacent tubes;
the partition wall further includes a second insert inserted between the first section and the second section,
the second insert is in a comb shape and includes a second base and a plurality of second blades,
the second blades are extended from the second base,
each of the second blades inserted between two tubes, which are adjacent to each other, and
the first insert and the second insert are opposed to each other.

2. The heat exchanger according to claim 1 , wherein
two of the tubes, which are adjacent to each other, define one of the drain passages therebetween.

3. The heat exchanger according to claim 2 , wherein
the tubes are exposed on a side of one of the drain passages, without being in contact with the fins.

4. The heat exchanger according to claim 1 , wherein
two of the tubes, which are adjacent to each other, the partition wall, and a fin end of the fins define one of the drain passages thereamong.

5. The heat exchanger according to claim 1 , wherein
the drain passages and the tubes are arranged alternately.

6. The heat exchanger according to claim 1 , wherein each of the fins and one of the tubes form an air passage, and each of the drain passages is, in shape, different from a shape of the air passage.

7. The heat exchanger according to claim 1 , wherein
the first blades and the second blades are arranged alternately, and
each of the first blades and its corresponding second blades are located at a same level.

8. The heat exchanger according to claim 1 , wherein the core is a part of an evaporator configured to cool air flowing therethrough, and the drain passages are configured to conduct condensate, which is formed on the core, therethrough.

9. The heat exchanger according to claim 1 , wherein
the core is inclined at an angle.

10. The heat exchanger according to claim 9 , wherein
the drain passages are located on a lower side in the first section relative to a gravitational direction.

11. A heat exchanger comprising:
a plurality of tubes;
a plurality of fins stacked alternately with the tubes to form a core including a first section and a second section; and
a partition wall partitioning between the first section and the second section, wherein
the first section has drain passages in the vicinity of the partition wall,
each of the drain passage has a width, and
the width is greater than a fin pitch of the fins in a lateral direction of the tubes, wherein the fin pitch is a length between two peaks of the fins in the lateral direction; wherein
the partition wall includes a first insert inserted between the first section and the second section, the first insert is in a comb shape and includes a first base and a plurality of first blades,
the first blades are extended from the first base, and
each of the first blades inserted between two adjacent tubes; the partition wall further includes a second insert inserted between the first section and the second section,
the second insert is in a comb shape and includes a second base and a plurality of second blades,
the second blades are extended from the second base, each of the second blades inserted between two tubes, which are adjacent to each other, and the first insert and the second insert are opposed to each other.
