Martin’s Heat Exchanger Unit (HXU) is designed as an In-Row integrated solution to remove server-generated heat from a typical IT server room environment using a chilled water supply. It is configured in the same style and size as Martin’s server and equipment cabinets, and Power Distribution Enclosures (PDEs).
A controlled supply of chilled water is provided to each Heat Exchanger. The chilled water passes through the heat exchanger coils where it collects heat from the rear (hot aisle) and the rear of the adjacent server cabinets and exits the Heat Exchanger and returns to the chiller.
The front mounted fans pull the heated air from the rear through the Heat Exchanger coils where it is cooled and exhausted to the front (cold aisle) and front sides, if desired, directly into adjacent server cabinets.
THE HEAT EXCHANGER UNIT IS AVAILABLE IN THREE CONFIGURATIONS:
In Row “open loop” configuration
Incorporates all of the controls, display, monitoring devices, heat exchange coils and plumbing into each HXU enclosure which is located between In Row server cabinets and optionally on each end of the row. Each unit operates independently from the other HXUs. The heat is collected from the “hot aisle”, pulled through the heat exchange coils, and the cooled air exhausts into the “cold aisle”.
In Row “closed loop” configuration
Incorporates the same features as the above except the front and rear doors are solid. The hot air is collected directly from the rear of the server cabinets, pulled through the coils, and the cooled air exhausts directly into the front of the adjacent server cabinets
The hybrid configuration incorporates both airflow solutions in the same configuration so that the hot air is collected from both the hot aisle and directly from the rear of the servers, and the cold air exhausts both into the cold aisle as well as directly to the fronts of the adjacent servers.
