Abstract

A cooling jacket includes: first and second pipe portions through which a coolant flows; and a main portion connected with side surfaces of the first and second pipe portions, defining, with a single member, a flow path through which the coolant flows, and cooling an object to be cooled.

First claim

What is claimed is:

1. A cooling jacket, comprising:
first and second pipe portions through which a coolant flows;
a main portion connected with side surfaces of the first and second pipe portions, defining, with a single member, a flow path through which the coolant flows, and cooling an object to be cooled;
wherein the first pipe portion and the main portion are fixed with a bonding agent which is hardened,
wherein an end of the main portion is inserted into an inside of the first pipe portion, beyond an inner surface of the first pipe portion,
wherein the first pipe portion includes an inner surface and an outer surface,
wherein the main portion includes an inner surface and an outer surface, and
wherein the bonding agent includes:
a first bonding agent portion bonding the inner surface of the first pipe portion and an upper surface of the outer surface of the main portion,
a second bonding agent portion bonding the outer surface of the first pipe portion and the upper surface of the outer surface of the main portion,
a third bonding agent portion bonding the inner surface of the first pipe portion and a lower surface of the outer surface of the main portion, and
a fourth bonding agent portion bonding the outer surface of the first pipe portion and the lower surface of the outer surface of the main portion,

wherein the upper surface and the lower surface of the outer surface of the main portion are positioned at a distance from the inner surface of the first pipe, and
wherein the first bonding agent portion and the third bonding agent portion do not leak into the inner surface of the main portion.

2. The cooling jacket of claim 1 ,
wherein a direction in which the coolant flows into the first pipe portion is an axial direction of the first pipe portion, and
wherein the direction in which the coolant flows into the first pipe portion is different from a direction in which the coolant flows through the main portion.

3. An electronic device comprising a cooling jacket, the cooling jacket comprising:
first and second pipe portions through which a coolant flows; and
a main portion connected with side surfaces of the first and second pipe portions, defining, with a single member, a flow path through which the coolant flows, and cooling an object to be cooled;
wherein the first pipe portion and the main portion are fixed with a bonding agent which is hardened,
wherein an end of the main portion is inserted into an inside of the first pipe portion, beyond an inner surface of the first pipe portion,
wherein the first pipe portion includes an inner surface and an outer surface,
wherein the main portion includes an inner surface and an outer surface, and
wherein the bonding agent includes:
a first bonding agent portion bonding the inner surface of the first pipe portion and an upper surface of the outer surface of the main portion,
a second bonding agent portion bonding the outer surface of the first pipe portion and the upper surface of the outer surface of the main portion,
a third bonding agent portion bonding the inner surface of the first pipe portion and a lower surface of the outer surface of the main portion, and
a fourth bonding agent portion bonding the outer surface of the first pipe portion and the lower surface of the outer surface of the main portion,

wherein the upper surface and the lower surface of the outer surface of the main portion are positioned at a distance from the inner surface of the first pipe, and
wherein the first bonding agent portion and the third bonding agent portion do not leak into the inner surface of the main portion.

4. The cooling jacket of claim 1 , wherein at least a part of the main portion is exposed.

5. The cooling jacket of claim 1 , wherein the end of the main portion is located within the first pipe portion and does not contact the inner surface of the first pipe portion.

6. The cooling jacket of claim 1 , wherein the bonding material is a wax material.

7. The cooling jacket of claim 1 ,
wherein the coolant flows through the first pipe portion, the main portion and the second pipe portion, in this order, and
wherein a depth of the end of the main portion inserted into the inside of the first pipe portion is greater than a depth of another end of the main portion inserted into an inside of the second pipe portion.
