Abstract

A manifold includes: a branch pipe including an inflow port and a plurality of outflow ports; and a partition wall that partitions an inside of the branch pipe into a side of the inflow port and a side of the plurality of outflow ports and includes: a plurality of through-holes that have a total opening area greater than an opening area of the inflow port; and a plurality of first facing portions that face the respective outflow ports.

First claim

What is claimed is:

1. A manifold comprising:
a branch pipe including an inflow port and a plurality of outflow ports; and
a partition wall that partitions an inside of the branch pipe into a side of the inflow port and a side of the plurality of outflow ports and includes:
a first facing portion provided at the inflow port and configured to face a part of the plurality of outflow ports;
a second facing portion configured to extend from the first facing portion in a longitudinal direction of the partition wall, face another part of the plurality of outflow ports and has a narrower width than a width of the first facing portion; and
a plurality of through-holes provided at both sides of the second facing portion and configured to extend along the second facing portion,

an opening area of each of the plurality of through-holes is smaller than an opening area of each of the outflow ports.

2. The manifold according to claim 1 , wherein the partition wall is disposed at a position intermediate between the inflow port and the outflow ports or a position closer to the inflow port than the outflow ports.

3. The manifold according to claim 1 , wherein the second facing portion perpendicularly intersects a center line of the outflow ports.

4. The manifold according to claim 1 , wherein the plurality of through-holes have a total opening area greater than an opening area of the inflow port.

5. The manifold according to claim 1 , wherein the first facing portion perpendicularly intersects a center line of the inflow port.

6. The manifold according to claim 1 , wherein the branch pipe is formed in a cylindrical shape, and wherein the inflow port and the plurality of outflow ports are disposed on an outer peripheral surface of the branch pipe.

7. The manifold according to claim 6 , wherein the partition wall includes another second facing portion configured to extend in the longitudinal direction of the partition wall in parallel with the second facing portion.

8. The manifold according to claim 6 , wherein the partition wall continues from a bottom surface of one end of the branch pipe to a bottom surface of the other end of the branch pipe in the axial direction.

9. An information processing apparatus comprising:
a manifold including:
a branch pipe with an inflow port and a plurality of outflow ports; and
a partition wall that partitions an inside of the branch pipe into a side of the inflow port and a side of the plurality of outflow ports and includes:
a first facing portion provided at the inflow port and configured to face a part of the plurality of outflow ports;
a second facing portion configured to extend from the first facing portion in a longitudinal direction of the partition wall, face another part of the plurality of outflow ports and has a narrower width than a width of the first facing portion; and
a plurality of through-holes provided at both sides of the second facing portion and configured to extend along the second facing portion;

a circulation member that circulates a cooling liquid by combining the cooling liquid flowing out from the plurality of outflow ports and sending the combined cooling liquid to the inflow port; and
a plurality of electronic components that are cooled by the cooling liquid flowing out from the plurality of outflow ports,
an opening area of each of the plurality of through-holes is smaller than an opening area of each of the outflow ports.

10. The information processing apparatus according to claim 9 , wherein the partition wall is disposed at a position intermediate between the inflow port and the outflow ports or a position closer to the inflow port than the outflow ports.

11. The information processing apparatus according to claim 9 , wherein the second facing portion perpendicularly intersects a center line of the outflow ports.

12. The information processing apparatus according to claim 9 , wherein the plurality of through-holes have a total opening area greater than an opening area of the inflow port.

13. The information processing apparatus according to claim 9 , wherein the first facing portion perpendicularly intersects a center line of the inflow port.

14. The information processing apparatus according to claim 9 , wherein the branch pipe is formed in a cylindrical shape, and wherein the inflow port and the plurality of outflow ports are disposed on an outer peripheral surface of the branch pipe.

15. The information processing apparatus according to claim 14 , wherein the partition wall includes another second facing portion configured to extend in the longitudinal direction of the partition wall in parallel with the second facing portion.

16. The information processing apparatus according to claim 14 , wherein the partition wall continues from a bottom surface of one end of the branch pipe to a bottom surface of the other end of the branch pipe in the axial direction.
