Gasket mounted between power modules for separating coolant passage

摘要

Disclosed herein is a gasket mounted between power modules for separating a coolant passage, the gasket is inserted between an upper power module formed with a cooling passage on a lower surface thereof and a lower power module formed with a cooling passage on an upper surface to seal coupling surfaces of the upper power module and the lower power module, wherein a circumference of an upper surface of the gasket is closely attached on the lower surface of the upper power module, a circumference of a lower surface of the gasket is closely attached on the upper surface of the lower power module, and the cooling passage of the upper power module and the cooling passage of the lower power module are separated up and down by the gasket.

主权项

1. A gasket for use in a vehicle and to be mounted between upper and lower power modules, a bottom of the upper power module comprising a first recessed surface and a first periphery surrounding the first recessed surface, a top of the lower power module comprising a second recessed surface and a second periphery surrounding the second recessed surface, the gasket comprising a plate shaped body which comprises:
an upper surface configured to be liquid-tightly attached to the first periphery of the bottom of the upper power module such that a first coolant passage is formed between the upper surface and the first recessed surface of the upper power module, a lower surface configured to be liquid-tightly attached to the second periphery of the top of the lower power module such that a second coolant passage is formed between the lower surface and the second recessed surface of the lower power module, and at least one flow control structure formed on the upper surface and protruding toward the first recessed surface while not contacting the first recessed surface.
