Chengdu Xihe Heatsink Factory was built in the mid-1980s, with the construction area of more than 10,000 square meters, specialized in manufacturing Heat Sink for power semiconductor device, undertaking all kinds of heatsink` design, production and sales.

   For a long time, Xihe Heatsink people always regard "Survive with quality, Effectiveness with security, Develop with science and technology" as principles of running factory, regard the sprit of "Dare to be climbing, always create the first" as motivation, has created many miracles one by one in the relevant counterparts and played an important role for the using of Chinese electronic industry power components.

  At present, the enterprise has become a leading enterprise and created “Nine of the most” in the domestic counterparts.

  •  Design ability is the strongest
  •  Maximum machining equipments
  •  Extrusion equipment is the most advanced
  •  Welding equipment is the most advanced (no welding accessories)
  •  The widest processing size at one time (800mm) 
  •  The longest perimeter extruded at one time (14,000mm)
  •  The most new products (Several hundreds) 
  •  The biggest solo product power (Wind-cooling heatsink 20,000W, liquid-cooling heatsink 10,000W.)
  •  The best testing equipment (Wind-resistant and heat-resistant curve testing machines), with the ability of producing heatsinks more than 3,000 tons annually.

   Our factory uses brand “Dongxia” as our registered trademark, has passed ISO9001:2008 Quality Management System Certification. The exiting products range including tower-shape, bamboo-shape, dense teeth, controllable silicon, general profiles, combined profiles, insert, shovel, heat pipe, water cooling, LED lamps and lanterns, water-cooling casting, non-standard special series of heat sink and heatsink accessories.

   At present, from mold-designing, mold-making, profiles-extruding, machinery-processing, testing thermal resistance, making thermal image, optimizing the design of power dissipation to finished heat sink, all solely completed by our factory, thereby greatly reducing the supply cycle and improving product quality to meet the users` demand better.

   Due to the development of business, in order to meet the market demand, we established Chengdu Donghao Heatsink Co.,Ltd In July 2014. Hope to service for our customers better.
