HEAT EXCHANGER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18372505 titled 'HEAT EXCHANGER
Simplified Explanation
The patent application describes a heat exchanger with refrigerant tubes, fins, and sacrificial sheets to prevent corrosion. The sacrificial sheet has a lower corrosion potential than the refrigerant tube.
- The heat exchanger includes refrigerant tubes for refrigerant flow.
- Fins are placed between adjacent refrigerant tubes to conduct heat.
- Sacrificial sheets are positioned between refrigerant tubes and fins to prevent corrosion.
- The sacrificial sheet has a lower corrosion potential than the refrigerant tube.
Potential Applications
The technology can be used in various heat exchange systems, such as air conditioning units, refrigeration systems, and heat pumps.
Problems Solved
1. Corrosion of refrigerant tubes in heat exchangers. 2. Maintaining the efficiency and longevity of heat exchange systems.
Benefits
1. Increased durability and lifespan of heat exchangers. 2. Improved heat transfer efficiency. 3. Reduced maintenance and repair costs.
Potential Commercial Applications
"Corrosion-Resistant Heat Exchanger Technology for HVAC Systems"
Possible Prior Art
Prior art may include traditional sacrificial anode systems used in marine applications to prevent corrosion in metal structures.
Unanswered Questions
How does the sacrificial sheet prevent corrosion in the heat exchanger?
The sacrificial sheet acts as a sacrificial anode, attracting corrosion away from the refrigerant tube due to its lower corrosion potential.
What materials are commonly used for sacrificial sheets in heat exchangers?
Common materials for sacrificial sheets include zinc, aluminum, and magnesium, which have lower corrosion potentials compared to the refrigerant tubes.
Original Abstract Submitted
A heat exchanger is provided that may include a plurality of refrigerant tubes through which refrigerant flows, a fin disposed between adjacent refrigerant tubes to conduct heat, and a sacrificial sheet provided between a refrigerant tube of the plurality of refrigerant tubes and the fin and configured such that a first surface thereof contacts the refrigerant tube and a second surface thereof contacts the fin. A corrosion potential of the sacrificial sheet may be lower than a corrosion potential of the refrigerant tube.
