Patents by Inventor Chang-Wen Tien

Chang-Wen Tien has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7234316
    Abstract: A modularized high efficiency cooling device in a cooling mechanism, which includes at least one exchanger, at least one gas cooling device, at least one water cooling unit, at least one chiller unit, at least one chiller pump and at least one pair of copper tube. The cooling device adopts modularized design so that it can be assembled to form different units according to consumer demands and has an effect of frequency conversion. The assembled unit can be installed in different places. One machine of the cooling device can be maintained individually as well as the other machines of the cooling device that are in use normally. This reduces maintenance fees and is convenient.
    Type: Grant

  • Patent number: 6338256
    Abstract: A high efficiency cooling device in a cooling mechanism comprises a heat exchange unit 20, a gas cooling unit 21, a water cooling unit 22 and a water circulation unit 23. The heat exchange unit is an upright round frame formed of a plurality of upright heat radiating fins and refrigerant tubes which are densely wound around these heat radiating fins. The round frame is enclosed with a hollow chamber. A water cooling unit is installed in the hollow chamber of the heat exchange unit. The water cooling unit mainly includes least one spray disk driven by a motor or other dynamic device and a first water supply tube for supplying cooling water to the spray disk. Thereby, cooling water will uniformly spray to each heat exchange unit due to the inertial force of rotation itself, then flows downwards straightly along the heat radiating fin so as to achieve a high efficiency cooling effect.
