Product Description

Overview

The Coolant Distribution Unit (CDU) is the central component of the water cooling system, responsible for efficiently distributing the cooling medium to meet the cooling needs of various applications. It ensures the system operates stably by incorporating additional monitoring and support devices. The CDU on the secondary side of the heat exchange unit is primarily used for controlling heat exchange in liquid cooling heat sink systems.

Our Advantages

Our cutting-edge design enhances the efficiency and dependability of the water cooling system. It features six channels linking the main pipeline to the water separator, using clamps and rubber hoses to eliminate installation errors.

A multi-stage centrifugal pump ensures smooth coolant flow, while an integrated expansion tank compensates for temperature fluctuations to maintain consistent pressure levels.

To prevent oxidation corrosion and cavitation, the unit includes an automatic air vent valve that promptly eliminates non-condensable gases. Additionally, a 150μm filter is equipped in the main path to preserve coolant quality.

Frequently Asked Questions

Q: What is the primary function of the Coolant Distribution Unit (CDU)? A: The CDU acts as the central hub of a water cooling system, distributing the cooling medium efficiently and controlling heat exchange for liquid cooling heat sink systems.

Q: Which materials are used for the piping to ensure durability? A: The unit utilizes corrosion-resistant 304 stainless steel or higher-grade materials for all piping components to ensure long-term reliability.

Q: Does the CDU support remote monitoring and integration? A: Yes, it features a standard Modbus TCP communication protocol, enabling rich detection, alarm, and protection functions that can be integrated into data center management systems.

Q: How does the system handle air and impurities in the coolant? A: It includes an automatic air vent valve to eliminate non-condensable gases and a 150μm filter in the main path to preserve coolant quality and prevent cavitation.

Q: Is the cooling capacity adjustable? A: The CDU supports a broad cooling capacity range from 20kW up to 1500kW, and its modular design allows for increased capacity based on specific demand.

Q: What interface is used for the control system? A: The system is equipped with a 10-inch touch screen that offers multi-level authority control for temperature, flow, and differential pressure monitoring.
