Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If an electric heater is directly mounted in a copper tube to heat the refrigerant, then the thermal efficiency of the refrigerant is improved, but the manufacturing complexity increases and electrical safety problems occur
Solution Approach 1:
The patent introduces a magnetic conductor plate as an intermediary between the electromagnetic induction coil and the refrigerant. The coil generates an alternating magnetic field that induces eddy currents in the magnetic conductor plate, which then generates heat through resistive heating. This heat is transferred to the refrigerant through thermal conduction, achieving efficient heating without direct electrical contact with the refrigerant.
Solution Approach 2:
The patent replaces the direct electrical heating system (electric heater mounted in copper tube) with an electromagnetic induction heating system. The electromagnetic induction coil generates an alternating magnetic field that induces currents in the magnetic conductor plate, converting electrical energy to thermal energy through electromagnetic induction rather than direct electrical contact.
2Use of energy by moving object
If an electric heater is directly mounted in a copper tube to heat the refrigerant, then the thermal efficiency of the refrigerant is improved, but the sealing reliability deteriorates
Solution Approach 1:
The magnetic conductor plate serves as a mediator that separates the electrical heating component from the refrigerant. The electromagnetic induction coil is mounted on the external surface of the heat exchanger, and the magnetic conductor plate is positioned between the coil and the refrigerant, eliminating the need for sealed junctions between electrical components and refrigerant-containing structures.
3Use of energy by moving object
If an electric heater is directly mounted in a copper tube to heat the refrigerant, then the thermal efficiency of the refrigerant is improved, but electrical safety problems occur
Solution Approach 1:
The magnetic conductor plate and heat exchanger structure serve as intermediaries that completely isolate the electrical components from the refrigerant. The electromagnetic induction coil generates the magnetic field externally, the magnetic conductor plate converts it to heat, and the heat is transferred through the heat exchanger walls to the refrigerant, ensuring complete electrical isolation and eliminating safety hazards.
4Speed
If the electromagnetic induction heating member is used to heat the refrigerant, then the heating speed is improved and electricity is separated from refrigerant, but the device complexity increases
Solution Approach 1:
The patent merges the electromagnetic induction heating function with the existing heat exchanger structure. The electromagnetic induction coil is mounted on the external surface of the heat exchanger, utilizing the heat exchanger's structure as the mounting base and thermal transfer path, thereby adding heating functionality without significantly increasing overall device complexity.
Solution Approach 2:
The heat exchanger structure serves multiple functions: it acts as the thermal transfer path for refrigerant heating, provides the mounting structure for the electromagnetic induction coil, and serves as part of the heating system infrastructure. This multi-functionality reduces the need for additional separate components.
