Abstract

A radiator includes: a tube through which a coolant flows; and a single tank including: a supplying chamber communicating with an end of the tube, for supplying the tube with the coolant; and a collecting chamber communicating with the other end of the tube, partitioned to the supplying chamber, and for collecting the coolant discharged from the tube.

First claim

What is claimed is:

1. A radiator comprising:
a tube through which a coolant flows; and
a single tank comprising:
a supplying chamber communicating with an end of the tube, for supplying the tube with the coolant;
a collecting chamber communicating with the other end of the tube, partitioned to the supplying chamber, and for collecting the coolant discharged from the tube;
an inlet nozzle extending from the supplying chamber; and
an outlet nozzle extending from the collecting chamber,

wherein the tube comprises:
first and second path portions extending from the tank in opposite directions;
a third path portion continuous to the first path portion and facing the first path portion; and
a fourth path portion continuous to the second path portion and facing the second path portion,

wherein the first and second path portions communicate to the supplying chamber, and the third and fourth path portions communicate to the collecting chamber,
wherein the inlet nozzle and the first and second path portions are arranged in a line, when viewed in such a direction that the inlet nozzle extends,
wherein the outlet nozzle and the third and fourth path portions are arranged in a line, when viewed in such a direction that the inlet nozzle extends,
wherein an outer surface of the first path portion is opposite to an inner surface of the first path portion facing an inner surface of the third path portion and is exposed to an outside of the radiator,
wherein an outer surface of the third path portion is opposite to the inner surface of the third path portion and is exposed to the outside of the radiator, and
wherein a length of the supplying chamber in such a direction that the first path portion extends is longer than a length of the supplying chamber in a direction perpendicular to such a direction that the first path portion extends, when viewed in such a direction that the inlet nozzle extends.

2. The radiator of claim 1 , wherein the supplying chamber is provided between the first and second path portions, and the collecting chamber is provided between the third and fourth path portions.

3. The radiator of claim 1 ,
wherein the coolant flows from the supplying chamber to the first and second path portions,
wherein the coolant flows from the first path portion to the collecting chamber through the third path portion, and
wherein the coolant flows from the second path portion to the collecting chamber through the fourth path portion.

4. The radiator of claim 1 , wherein the supplying chamber and the collecting chamber are arranged in such a direction that the first and third path portions are arranged.

5. An electronic device comprising a radiator, the radiator comprising:
a tube through which a coolant flows; and
a single tank comprising:
a supplying chamber communicating with an end of the tube, for supplying the tube with the coolant;
a collecting chamber communicating with the other end of the tube, partitioned to the supplying chamber, and for collecting the coolant discharged from the tube;
an inlet nozzle extending from the supplying chamber; and
an outlet nozzle extending from the collecting chamber,

wherein the tube comprises:
first and second path portions extending from the tank in opposite directions;
a third path portion continuous to the first path portion and facing the first path portion; and
a fourth path portion continuous to the second path portion and facing the second path portion,

wherein the first and second path portions communicate to the supplying chamber, and the third and fourth path portions communicate to the collecting chamber,
wherein the inlet nozzle and the first and second path portions are arranged in a line, when viewed in such a direction that the inlet nozzle extends,
wherein the outlet nozzle and the third and fourth path portions are arranged in a line, when viewed in such a direction that the inlet nozzle extends,
wherein an outer surface of the first path portion is opposite to an inner surface of the first path portion facing an inner surface of the third path portion and is exposed to an outside of the radiator,
wherein an outer surface of the third path portion is opposite to the inner surface of the third path portion and is exposed to the outside of the radiator, and
wherein a length of the supplying chamber in such a direction that the first path portion extends is longer than a length of the supplying chamber in a direction perpendicular to such a direction that the first path portion extends, when viewed in such a direction that the inlet nozzle extends.

6. The radiator of claim 1 , wherein a height of the first path portion and a height of the third path portion are lower than an upper surface of the tank and are higher than a bottom surface of the tank.
