Abstract

A cooling assembly includes a first heat exchanger and a first flow path pipe. The first heat exchanger comes into contact with a first heat generating component. The first flow path pipe is connected to the first heat exchanger. The first flow path pipe includes a first intermediate portion between one end of the first flow path pipe connected to the first heat exchanger and the other end of the first flow path pipe. The first heat exchanger includes a first fixing portion that fixes the first intermediate portion of the first flow path pipe. The first heat exchanger includes a metal cold plate in contact with the first heat generating component, and a synthetic resin cover on one side in a first direction with respect to the cold plate.

Claims (46)

1 . A cooling assembly comprising:

a first heat exchanger that comes into contact with a first heat generating component;

a first flow path pipe that is connected to the first heat exchanger; and

a second flow path pipe that is connected to the first heat exchanger; wherein

the first flow path pipe includes a first intermediate portion between one end of the first flow path pipe connected to the first heat exchanger and another end of the first flow path pipe; and

the first heat exchanger includes a first fixing portion that fixes the first intermediate portion of the first flow path pipe;

the first heat exchanger includes:

a cold plate made of metal that comes into contact with the first heat generating component; and

a cover made of synthetic resin that is on one side of the cold plate in a first direction;

the cover includes:

the first fixing portion;

an inflow portion through which a refrigerant flows into;

an outflow portion through which the refrigerant flows out;

the one end of the first flow path pipe is connected to the inflow portion;

one end of the second flow path pipe is connected to the outflow portion;

the first fixing portion includes a first through-hole penetrating the cover along the first direction;

a portion of a substantially annular fixing portion is in the first through-hole; and

the first intermediate portion of the first flow path pipe is in an internal space defined by the substantially annular fixing portion.

2 . The cooling assembly according to claim 1 , wherein

the first fixing portion further includes an inclined portion arranged on the one side of the first through-hole in the first direction; and

the inclined portion is inclined on a side of a second direction perpendicular or substantially perpendicular to the first direction.

3 . The cooling assembly according to claim 1 , wherein

the cold plate includes a guide portion at least partially overlapping the first through-hole in the first direction; and

the guide portion is connected to an end on the other side of the first through-hole in the first direction.

4 . The cooling assembly according to claim 3 , wherein the cold plate includes the guide portion on the one side in the first direction.

5 . The cooling assembly according to claim 1 , wherein the first fixing portion includes a substantially annular hook portion and an opening portion on the one side of the hook portion in the first direction.

6 . The cooling assembly according to claim 1 , further comprising:

a second heat exchanger that comes into contact with a second heat generating component; and

a third heat exchanger that comes into contact with a third heat generating component; wherein

the first heat exchanger is between the second heat exchanger and the third heat exchanger in a second direction orthogonal to the first direction;

the second heat exchanger and the third heat exchanger are connected via a third flow path pipe; and

the third heat exchanger is connected to the other end of the first flow path pipe.

7 . The cooling assembly according to claim 6 , wherein the first flow path pipe is between the first heat exchanger and the third heat exchanger in the second direction.

8 . The cooling assembly according to claim 1 , further comprising:

a fourth heat exchanger that comes into contact with a fourth heat generating component; and

a fifth heat exchanger that comes into contact with a fifth heat generating component; wherein

the first flow path pipe includes:

a first pipe connected to the fourth heat exchanger;

a second pipe between the fourth heat exchanger and the fifth heat exchanger; and

a third pipe between the fifth heat exchanger and the first heat exchanger.

9 . The cooling assembly according to claim 1 , further comprising:

a sixth heat exchanger that comes into contact with a sixth heat generating component; and

a fourth flow path pipe that is connected to the sixth heat exchanger; wherein

the first flow path pipe further includes a second intermediate portion between the one end of the first flow path pipe and the other end of the first flow path pipe;

the sixth heat exchanger includes a second fixing portion that fixes the second intermediate portion of the first flow path pipe; and

the other end of the second flow path pipe is connected to the sixth heat exchanger.
