Electric radiator for a ventilation, heating and/or air-conditioning system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric radiators in motor vehicle ventilation, heating, and air-conditioning systems face issues with the vulnerability of electronic connection elements to damage and the need for complex sealing to prevent fluid circulation.
Innovation Solution
The electric radiator incorporates a separating wall with an orifice that allows the electronic connection element between the temperature sensor and the electronic control device to pass through, reducing the path length and protecting the connection from damage, while a guide member and sealing element enhance mechanical guidance and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic connection element is routed externally from the housing to connect the temperature sensor to the control device, then the coupling flexibility is improved, but the connection element becomes vulnerable to damage and requires complex sealing
Solution Approach 1:
The patent introduces a separating wall with an orifice as an intermediary structure that mediates the connection between the temperature sensor and control device. The connection element passes through the orifice in the separating wall, which acts as a protected intermediary pathway, eliminating the need for external routing while maintaining coupling flexibility and protecting against damage.
2Adaptability or versatility
If the electronic connection element extends at a distance from the heating body and housing, then the installation flexibility is improved, but the connection element is susceptible to damage
Solution Approach 1:
The patent transitions the connection element routing from an external three-dimensional path to an internal path through the separating wall. By changing the routing dimensionality to pass through the wall thickness (from external surface mounting to internal through-orifice routing), the connection element is protected from external damage while maintaining installation flexibility.
3Reliability
If specific sealing of the coupling between the cable and housing is implemented, then the sealing reliability is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent merges the sealing function with the separating wall structure itself. The separating wall with its integrated orifice combines the structural separation function with the sealing function, eliminating the need for separate sealing operations between the cable and housing while maintaining sealing reliability.

Function Achieved in This Case
This configuration protects the electronic connection element from shearing and simplifies the sealing process, enhancing the reliability and assembly efficiency of the electric radiator.
Implementation Method 1
heating elements are arranged across an air flow to be heated... the heating elements are capable of increasing in temperature and the air flow circulating between the tubes of the electric radiator is heated
