Introduction
Liquid-to-Liquid Coolant Distribution Unit (CDU) , Installed in the cabinet. It is a core cooling device designed for high-density heat dissipation requirements, achieving efficient heat exchange through liquid circulation. Its core function is to absorb the heat of IT equipment through the coolant on the secondary side, and then transfer the heat to the outside through the external cooling system on the primary side (such as chilled water, natural cold sources, etc.), thereby maintaining the operation of IT equipment within a safe temperature range.
