The T-V coefficient is a safety limit value parameter that describes the buffering capacity design of the system based on pure water cooling medium. It is used to enable customers to quickly calculate and determine the number of servers that the CDU can cool. It is the product of the difference between the high and low temperature limit values of the cooling medium during system operation and the total volume of the coolant in the system. The internal volume of the CDU has already reached 35 liters.
