THROTTLE BODY WITH REDUCED DEPOSIT ACCUMULATION AND ENHANCED THERMAL CONDUCTIVITY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240035421 titled 'THROTTLE BODY WITH REDUCED DEPOSIT ACCUMULATION AND ENHANCED THERMAL CONDUCTIVITY

Simplified Explanation

The abstract describes a throttle body for an engine or fuel cell of a vehicle. The throttle body includes a cylindrical housing with an inner wall and a moveable blade valve that regulates air to the engine. The throttle body also has a dual-phase thermal composite coating (TCC) on the inner surface of the inner wall and the outer surface of the moveable blade valve. This coating enhances thermal conductivity and reduces deposit accumulation. The dual-phase TCC consists of two materials in specific weight percentages and has a contact angle and thermal conductivity within certain ranges.

  • The throttle body is a component of an engine or fuel cell in a vehicle.
  • It has a cylindrical housing with an inner wall and a moveable blade valve.
  • The moveable blade valve regulates air flow to the engine during vehicle operation.
  • The throttle body is coated with a dual-phase thermal composite coating (TCC).
  • The TCC is applied to the inner surface of the inner wall and the outer surface of the moveable blade valve.
  • The TCC enhances thermal conductivity and reduces deposit accumulation.
  • The dual-phase TCC consists of two materials in specific weight percentages.
  • The TCC has a contact angle between 100° and 160° and a thermal conductivity of at least 0.3 W/mK.

Potential applications of this technology:

  • Automotive industry: Throttle bodies with enhanced thermal conductivity can improve engine performance and fuel efficiency.
  • Fuel cell technology: Throttle bodies for fuel cells can benefit from reduced deposit accumulation, leading to improved reliability and longevity.

Problems solved by this technology:

  • Deposit accumulation: The dual-phase TCC reduces deposit accumulation on the inner surface of the throttle body, preventing potential performance issues and maintenance requirements.
  • Thermal conductivity: The enhanced thermal conductivity provided by the TCC helps in efficient heat dissipation, preventing overheating and potential damage to the engine or fuel cell.

Benefits of this technology:

  • Improved performance: The enhanced thermal conductivity and reduced deposit accumulation contribute to improved engine or fuel cell performance.
  • Increased efficiency: By regulating air flow more effectively, the throttle body can help optimize fuel consumption and improve overall efficiency.
  • Extended lifespan: Reduced deposit accumulation and improved heat dissipation can increase the lifespan of the throttle body and associated components.


Original Abstract Submitted

a throttle body for an engine or fuel cell of a vehicle is provided. the throttle body comprises a cylindrical housing comprising a first open end extending to a second open end defining an inner wall having an inner surface. the throttle body further comprises a moveable blade valve movably disposed on the inner wall and arranged to regulate air to the engine during operation of the vehicle. the moveable blade valve has an outer surface. the throttle body further comprises a dual-phase thermal composite coating (tcc) disposed on one of the inner surface of the inner wall and outer surface of the moveable blade valve for enhanced thermal conductivity and reduced deposit accumulation on the inner surface and the outer surface. the dual-phase tcc comprises a first material comprising between 10 wt % and 90 wt %, and a second material comprising between 10 wt % and 90 wt % of the dual-phase tcc. the dual phase tcc has a contact angle of between 100� and 160� and a thermal conductivity of at least 0.3 w/mk.
