The liquid cooling system is an important component of the nuclear magnetic resonance system, providing cooling water for high-power heating components (gradient power amplifiers, gradient coils, RF power amplifiers, RF electronic components, helium compressors, electronic and electrical cabinets) to ensure their normal operation. It consists of components such as a plate changer, an electric three-way valve, an expansion tank, a safety valve, an exhaust valve, a water pump, a filter, parameter monitoring sensors, and an electrical control box. It can be divided into seven parts: power amplifier cooling components, coil cooling components, RF cooling components, secondary side cooling cabinet (LCC), electrical cabinet air-cooled heat exchanger (CFC), primary side water-cooled unit, and pipeline components.

Solution

• Integrated chiller
• Split type chiller
• Liquid cooled cooling cabinet LCC
• Electric control cabinet air-cooled heat exchanger CFC
• Pipe assembly 

Features

• High temperature control accuracy and minimal pressure fluctuations during operation
• When the load heat changes significantly, it can effectively ensure that the water supply temperature is within the range of T ± 1 ℃
• Cabinet structure, high heat transfer capacity, independent control of flow rate in each branch, and precise monitoring of flow rate and temperature in each branch
• Redundant configuration of compressors and pumps, high reliability
