Radiant Vehicle Heating and Cooling System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle heating and cooling systems using blowers generate noise that interferes with audio and communication quality inside vehicles, as they blow air across heat exchangers, affecting the insulation's ability to block external noise.
Innovation Solution
Implementing a radiant heating and cooling system that uses infrared heaters, resistance heating wires, and solid state heating and cooling devices to provide thermal energy directly to the passenger compartment without air flow, thereby eliminating the need for blowers and associated noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a blower is used to blow air across a heat exchanger for heating or cooling, then the vehicle interior can be heated or cooled, but noise is generated that interferes with audio and communication quality
Solution Approach 1:
The patent removes the blower component entirely from the heating and cooling system. Instead of forcing air movement through a blower, the system uses radiant heating elements (such as infrared heaters) and natural convection to achieve thermal comfort without the noise-generating mechanical device.
Solution Approach 2:
The patent replaces the mechanical blower system with a radiant heating system that uses electromagnetic radiation (infrared) and natural thermal convection. This substitution eliminates the need for mechanical air movement while still achieving the desired heating and cooling effects in the vehicle interior.
2Temperature
If a blower blows air across a heat exchanger, then heating or cooling is provided, but the noise from the blower and airflow reduces the effectiveness of vehicle insulation against external noise
Solution Approach 1:
The patent removes the blower and forced air circulation system that generates internal noise. By eliminating this noise source, the vehicle's insulation can more effectively isolate the interior from external noise without having to compete with internal blower noise.
Solution Approach 2:
The patent replaces the mechanical air blowing system with radiant heating technology that transfers thermal energy directly through radiation rather than forced convection. This eliminates the aerodynamic noise generated by air movement across heat exchangers and through ducts.
3Temperature
If a blower system is used for heating or cooling, then temperature control is achieved, but additional noise interferes with music, shows, and passenger conversations
Solution Approach 1:
The patent extracts and removes the blower component that generates noise interfering with audio playback and passenger communication. The heating and cooling function is maintained through radiant and convective mechanisms that do not require mechanical air movement.
Solution Approach 2:
The patent substitutes the noisy mechanical blower system with a quiet radiant heating system using infrared technology. This allows high-quality audio playback and clear passenger conversations without the masking effect of blower and airflow noise.
