# Cooling Feed
|
|
|
|
A cooling feed represents a coolant loop delivered from a [cooling source](./coolingsource.md) to a particular rack or coolant distribution unit (CDU). The [cooling intakes](./coolingintake.md) a feed supplies are derived from the devices installed in the rack it serves, rather than referenced explicitly.
|
|
|
|
A single feed represents the entire loop, covering both the supply (cold) and return (warm) paths.
|
|
|
|
!!! tip
|
|
In-rack cooling equipment — coolant distribution units (CDUs), manifolds, and rear-door heat exchangers (RDHx) — is modeled as an ordinary (typically zero-U) [device](./device.md) installed in the rack. The device's make and model come from its [device type](./devicetype.md), and a [cooling intake](./coolingintake.md) component connects it to cooling. The feed serving such a device is derived from its rack.

## Fields
|
|
|
|
### Cooling Source
|
|
|
|
The [cooling source](./coolingsource.md) which supplies this feed.
|
|
|
|
### Rack
|
|
|
|
The [rack](./rack.md) which this feed serves (optional).
|
|
|
|
### Name
|
|
|
|
The feed's name or identifier. Must be unique to the assigned cooling source.
|
|
|
|
### Status
|
|
|
|
The feed's operational status.
|
|
|
|
!!! tip
|
|
Additional statuses may be defined by setting `CoolingFeed.status` under the [`FIELD_CHOICES`](../../configuration/data-validation.md#field_choices) configuration parameter.
|
|
|
|
### Cooling Capacity
|
|
|
|
The heat-removal capacity of the feed, in kilowatts (kW).
|
|
|
|
### Maximum Flow
|
|
|
|
The maximum rate of coolant flow supported by the feed, expressed as a numeric value with a selectable unit (liters per minute, cubic meters per hour, or gallons per minute). Must be a positive, non-zero value in the selected unit, or left blank.
