Abstract
A controller of a fuel system for a vehicle is provided in which heat is dissipated outside from a printed circuit board to cool the controller. The dissipated heat is utilized to maximize the efficiency of the purge operation using a canister by waste heat. The controller is integrated with an air filter for removing foreign substances from air to be suctioned into a canister, and is configured to realize heat exchange between air passing through the air filter and a motor driver.
Claims12
A controller of a fuel system for a vehicle, comprising:
- a mounting member mounted to a fuel tank, the mounting member being integrally provided at a top surface of the fuel tank with an accommodation portion and the top surface of the mounting member being a surface exposed to an outside of the fuel tank;
- a motor driver mounted in the accommodation portion to operate a motor of a fuel pump;
- and
- an air filter including a filter case, a filter module disposed in the filter case to remove foreign substances from air, an inlet port for allowing air to be introduced into the filter case therethrough, and an outlet port for allowing air, from which foreign substances have been removed while passing through the filter module, to be discharged from the filter case therethrough,
- wherein the filter case is formed integrally with the accommodation portion to realize heat exchange between air passing through the filter case and the motor driver,
- wherein a diaphragm is mounted between an internal space in the accommodation portion and an internal space in the filter case to separate the internal space in the accommodation portion and the internal space in the filter case from each other, and
- wherein the filter case includes:
- a main body formed integrally with the accommodation portion, the main body having therein an internal space in which the filter module is mounted;
- and
- a cover detachably coupled to the main body to seal the internal space in the main body.
