RFM-DGD series HP sinks, as our patent technology, are specially designed for railway locomotives. By adopting internationally advanced Heat Pipe technology, they are characterized with such properties as small heat resistance, rapid heat response, miniature weight, separate heat source and cold source.

Mainly for locomotive (electric locomotive, internal- combustion, subway system, suburb light rail) traction frequency and velocity system (Inverter Power Supply), and locomotive power supplying system(Traction Substation) and work for inverting, rectifying, power modules, locomotive lighting, locomotive air conditioning. The maximum dissipation power reaches 12000W.
