Abstract

A housing for electronic equipment includes a fan and a plurality of coolant channels in a passage of a cooling fluid introduced by the fan. A passage width defined by a cooling member blocking the passage, the member being one of the plurality of coolant channels closer to the fan, is smaller than a passage width defined by a cooling member blocking the passage, the member being one of the plurality of coolant channels farther away from the fan.

Claims

1. A housing for electronic equipment, comprising:

a fan; and

a plurality of coolant channels provided in a passage of a fluid introduced to the housing by the fan,

wherein a passage width defined by a cooling member blocking the passage, the member being one of the plurality of coolant channels closer to the fan, is smaller than a passage width defined by a cooling member blocking the passage, the member being one of the plurality of coolant channels farther away from the fan.

2. The housing according to claim 1, further comprising a plurality of airflow control plates provided in the passage as flow resistances to the fluid, wherein

the plurality of airflow control plates include a first control plate and a second control plate, the first control plate being closer to the fan than the second control plate in the passage, the flow resistance of the second control plate to the fluid being lower than the resistance of the first control plate.

3. The housing according to claim 2, wherein the plurality of airflow control plates are horizontally disposed at intervals.

4. The housing according to claim 2, wherein the plurality of airflow control plates are horizontally disposed in the housing at intervals.

5. The housing according to claim 2, further comprising:

a temperature sensor that detects a temperature of the fluid; and

a revolution controller that controls the speed of revolutions of the fan on the basis of the temperature detected by the temperature sensor.

6. The housing according to claim 5, further comprising a flow rate controller that controls a flow rate of the coolant fluid in the coolant channels on the basis of the temperature detected by the temperature sensor.

7. The housing according to claim 2, wherein the fan is attachable to and detachable from the housing.

8. The housing according to claim 2, wherein

the plurality of coolant channels are tubular, and

the plurality of airflow control plates extend from surfaces of the tubular coolant channels vertically with respect to a tube axis and are integrated with the plurality of coolant channels.

9. The housing according to claim 2, wherein the second control plate defines an opening ratio or opening area for the flow of the fluid larger than an opening ratio or opening area defined by the first control plate.

10. The housing according to claim 2, wherein the second control plate is inclined toward a flowing direction of cooling air compared with the first control plate.

11. The housing according to claim 2, wherein the second control plate is sparsely disposed compared with the first control plate.

12. A housing including electronic equipment therein, the housing comprising:

a fan provided in the housing and introduces a fluid into the housing as a cooling fluid to be supplied to the electronic equipment included in the housing;

a plurality of airflow control plates disposed in a passage for cooling air as flow resistances to the cooling air; and

a plurality of coolant channels provided at the plurality of airflow control plates and carry coolant for absorbing heat of the fluid,

wherein the plurality of airflow control plates include a first control plate and a second control plate, the first control plate being closer to the fan than the second control plate in the passage of the cooling fluid, the flow resistance of the second control plate to the cooling fluid being lower than the resistance of the first control plate.
