Abstract
The present disclosure is directed to a power module that powers and controls various electronics, such an electric motor of an electric vehicle. The device includes a cooling jacket and a plurality of the heat sinks. The cooling jacket includes seats, an inlet channel, and an outlet channel. Each of the seats includes a primary cavity, a secondary cavity, inlets, and outlets. The heat sinks screw into the primary cavities of the seats. Various circuitry and a printed circuit board are positioned on the heat sinks.
Claims20
A device, comprising:
- a cooling jacket including:
- an inlet channel configured to receive a coolant;
- an outlet channel;
- and
- a seat;
- and
- a heat sink inserted into the seat, the seat being fluidically coupled between the inlet channel and the outlet channel such that the coolant is able to flow from the inlet channel, into the seat and contact the heat sink, and to the outlet channel.
A device, comprising:
- a cooling jacket including:
- an inlet channel;
- an outlet channel;
- and
- a plurality of seats fluidically coupled to the inlet channel and the outlet channel;
- and
- a plurality of heat sinks configured to screw into the plurality of seats, respectively.
A method, comprising:
- positioning circuitry on a heat sink;
- screwing the heat sink into a seat of a cooling jacket, the cooling jacket including an inlet channel and an outlet channel, the seat being fluidically coupled to the inlet channel and the outlet channel;
- and
- coupling a printed circuit board to the heat sink, the printed circuit board being spaced from the heat sink by the circuitry, the printed circuit board being electrically coupled to the circuitry.
