Abstract: A cooling assembly for a data center rack includes: a chassis; a heat exchanger connected to the chassis, the heat exchanger being disposed vertically at least in part between upper and lower ends of the chassis, and at least one lower bracket connected to a lower end portion of the chassis. The heat exchanger includes: a cooling coil for circulating a cooling fluid therethrough; and a plurality of fins connected to the cooling coil, the fins being spaced from one another to allow air flow therebetween. Each of the at least one lower bracket is a single piece of sheet metal bent into shape and includes a supporting wall extending frontward from the lower end portion of the chassis, the supporting wall being configured to receive at least in part a lower end of the data center rack thereon.
