Title:
WATER-COOLED THIN FILM CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2018/126559
Kind Code:
A1
Abstract:
A water-cooled thin film capacitor (2), comprising a shell (2-1). A cooling cavity (2-2) and a capacitor core are provided in the shell (2-1); the capacitor core is connected to a direct current output end (2-4) by means of a bus provided in the shell (2-1); the direct current output end (2-4) is exposed out of the shell (2-1) at the back side of an opening of the cooling cavity (2-2); liquid cooling interfaces (2-7) communicated with the cooling cavity (2-2) are respectively provided at the left and right sides of the opening of the cooling cavity (2-2); a direct current input end (2-3) is provided at the front side of the shell (2-1). An IGBT is provided on the shell (2-1) of the thin film capacitor (2) to form a strong electrical device for a vehicle-mounted driver. A water-cooling structure is additionally provided on the shell (2-1) of the capacitor (2), and the bus for connecting the capacitor (2) and the IGBT (3) is built in the capacitor core, i.e., a water cooling plate, a housing, and the bus are integrated, so that not only the structure of the driver is simplified, but also the overall performance of the unit is improved. The integrated strong electrical device has not only an energy storage function of the capacitor but also a heat dissipation function of an insulated gate bipolar transistor. In a driving circuit, the strong electrical device can not only provide current and voltage supports for a high-frequency switch of the insulated gate bipolar transistor, but also can perform water-cooling heat dissipation on the insulated gate bipolar transistor by means of a water path thereof.
