  • Publication number: 20200260611
    Abstract: A water-cooled motor controller includes a capacitor, a water-cooled plate, and a power module stacked in a controller housing. The power module is fixedly connected to the water-cooled plate. The water-cooled plate is provided with a cooling medium flow channel on one side facing the power module, and the other side of the water-cooling plate on which the cooling medium flow channel faces away from the power module side contacts the capacitor through an insulating and thermally conductive material for heat exchange. The water-cooled plate and the controller housing are fixedly connected to each other with a cooling medium passage provided therebetween. A cooling medium flows in from the controller housing, and then flows out of the controller housing after being heat exchanged by the water-cooled plate. The present invention utilizes upper and lower surfaces of the water-cooled plate to dissipate heat from the capacitor and the power module simultaneously.

  • Publication number: 20180291458
    Abstract: Disclosed is use of a panel of gastric cancer (GC)-related genes in clinical applications. The present invention is based on a panel of 53 genes related to prognosis in GC and detection of their expression levels in clinical samples to calculate prognostic scores, so as to evaluate clinical prognosis of GC patients and its other applications. This score system is useful for assisting in treatment selection for GC patients and predicting the response to therapeutic intervention, to determine the degree of benefit of patients from chemotherapy and targeted therapy, thus avoiding overtreatment, reducing medical cost, and achieving personalized medicine. Accordingly, a 53-gene expression assay kit is designed and developed according to this system and different detection technology platforms.

  • Patent number: 9795066
    Abstract: An inverter is provided. In the inverter, an electronic device is disposed inside a first enclosure; a heat radiator and a cooling fan are disposed inside a second enclosure; a magnetic element is disposed outside the first enclosure and the second enclosure. In this way, the cooling effect on the electronic device inside the first enclosure and the heat radiator inside the second enclosure are increased as they may be less affected by the heat generated by the magnetic element. It is also beneficial to heat dissipation of the magnetic element. The cooling fan blows the heat radiator for heat dissipation; the magnetic element does not block the relatively cold air flowing through the heat radiator. Therefore, a less obstructed air duct is formed, and the dissipation effect is improved.
