Rack Mounted Type Liquid-cooled Load Bank

With the advent of the era of the Internet of everything, the energy consumption problem of data centers has become increasingly prominent. In order to achieve the goal of carbon neutrality, green data centers using liquid cooling technology have received more and more attention and application. 


The liquid-cooled load developed by Sunwin company for green data centers has greatly reduced power consumption and has the advantages of no noise, fast heat conduction, constant power, and AC/DC universality, providing users with a more energy-saving and efficient solution.


Main Features

 

Ultra-quiet

Adopting liquid cooling, no fan is required. Under the same cooling conditions, no noisy noise is generated, creating a quiet and comfortable working environment.

 

Fast cooling

The heat conduction capacity of liquid is 25 times that of air, with higher heat dissipation efficiency, lower operating temperature, lower component loss than air-cooled load, longer life, and 30%-50% power consumption can be saved.

 

Simulation of real working conditions

It is more compatible with liquid-cooled data centers, and can simulate and verify the actual heating conditions, cooling effects, power supply load capacity, line reliability, etc. of the server in the computer room.

 

Expandability

Multiple rack-mounted modules can be connected in parallel to form a cabinet-type load, and multiple cabinets can be connected in parallel to form any power. Standard interfaces are used between modules, which is convenient for expansion and upgrading.

 

Universal AC and DC

Both AC and DC power supplies can be tested, with wide applicability, and 1kW step value can be adjusted to meet the power supply tests of computer rooms of various forms and different powers.

 

Status monitoring

The LCD screen can display information and parameters such as inlet and outlet water pressure, inlet and outlet water temperature, flow, water tank temperature, alarm, etc., to control the working dynamics in real time.
