Abstract

An apparatus for a fire suppressant system on a server rack includes an integrated battery feature, a manifold, a conduit, and a control card, where the integrated battery feature includes a plurality of battery cells in an enclosure. A first end of the conduit coupled to a control valve on the manifold and a second end of the conduit coupled to the integrated battery feature. The control card configured to open the control valve on the manifold, where the control valve is configured to release a fire suppressant into the enclosure of the integrated battery feature. In one embodiment, the fire suppressant is contained within a pressurized fire suppressant reservoir mounted on the server rack. In another embodiment, the fire suppressant is a cooling fluid diverted from a radiator cooling unit on the server rack.

First claim

What is claimed is:

1. An apparatus for a fire suppressant system, the apparatus comprising:
an integrated battery feature, a manifold, a conduit, and a control card, wherein the integrated battery feature includes a plurality of battery cells in an enclosure;
a first end of the conduit coupled to a control valve on the manifold and a second end of the conduit coupled to the integrated battery feature;
the control card configured to open the control valve on the manifold, wherein the control valve is configured to release a cooling fluid into the enclosure;
a fluid manifold conduit and a radiator cooling unit valve, wherein a first end of the fluid manifold conduit is coupled to the manifold and a second end of the fluid manifold conduit is coupled to the radiator cooling unit valve; and
the radiator cooling unit valve is configured to divert the cooling fluid to the fluid manifold conduit in a first configuration, wherein the cooling fluid is a fire suppressant.

2. The apparatus of claim 1 , further comprising:
the radiator cooling unit valve configured to divert cooling fluid to at least one processor drawer with one or more electronic components in a second configuration.

3. The apparatus of claim 2 , further comprising:
a cooling fluid pump coupled to the radiator cooling unit valve, wherein the cooling fluid pump is configured to provide the cooling fluid to the radiator cooling unit valve.

4. The apparatus of claim 1 , further comprising:
a fan disposed at a first end of the integrated battery feature, wherein a first end of the fan is configured to direct airflow at a second end of the fan towards the plurality of battery cells; and
a mechanical fan louver assembly positioned at the second end of the fan, wherein the mechanical fan louver assembly is configured to create a watertight seal at the second end of the fan in a closed position.

5. The apparatus of claim 4 , further comprising:
a perforation louver assembly positioned at a second end of the integrated battery feature, wherein the perforation louver assembly is configured to create a watertight seal at the second end of the integrated battery feature in the closed position.

6. The apparatus of claim 1 , further comprising:
a drain positioned on a lower surface of the enclosure for the integrated battery feature, wherein the drain is configured to remove the cooling fluid from the integrated battery feature.

7. The apparatus of claim 1 , further comprising:
a fluid level sensor of the integrated battery feature configured to measure an amount of the cooling fluid within the integrated battery feature.
