Abstract
A multi-channel refrigerant controller with changeable refrigerant evaporation implements a refrigerant-channel assembly to control refrigerant in terms of flow and direction, and, when working with a phase-change cooler, well supports both high- and low-temperature operations. The multi-channel refrigerant controller includes a refrigerant-channel assembly, a solenoid-valve assembly, a capillary-tube assembly and an execution controller. When receiving settings for a high- or low-temperature operation, the execution controller correspondingly opens relevant refrigerant channels in the refrigerant-channel assembly to guide the refrigerant influents through capillary tubes of different flow capacities to different sites on the phase-change cooler for evaporation cooling. In a high-temperature operation, the controller effectively cools down the otherwise hot, gaseous return refrigerant, so as to not only protect the cooling system's components and operators, but also improve cooling efficiency and capability.
