Cooling solutions for the refrigeration industry | Fengheng Technology
Fengheng Technology provides professional heat dissipation solutions for the refrigeration industry. Its products are widely used in refrigerators, freezers, display cases, ice makers, condensers, evaporators and other equipment, meeting the stringent requirements of refrigeration equipment for low-temperature start-up, high reliability and long life.
I. Four Core Pain Points in Heat Dissipation in the Refrigeration Industry
Pain Point 1: The Challenge of Fan Startup in Low-Temperature Environments
Phenomenon:When the internal temperature of a freezer or refrigerator is low (below -20℃), a regular fan will not start or will rotate slowly.
root cause:Fan lubricating oil solidifies at low temperatures, increasing starting resistance.
Industry Standards:The cooling equipment fan must be able to operate at temperatures ranging from -25℃ to +40℃.
Pain Point 2: Insufficient heat dissipation from the condenser leads to decreased cooling performance.
Phenomenon:Insufficient airflow from the condenser fan causes the compressor to run continuously for extended periods, increasing power consumption.
root cause:The fan's air pressure is insufficient to overcome the air resistance of the condenser fins.
Industry data:Poor condenser heat dissipation can lead to an increase in compressor power consumption of 15-25%.
Pain Point 3: Reliability Requirements for 24/7 Continuous Operation
Phenomenon:Commercial freezers and display cases operate year-round, and insufficient fan life leads to reduced airflow.
root cause:Cheap oil-bearing fans have a lifespan of only 10,000 to 20,000 hours
Industry feedback:Supermarket customers complained, "The refrigerator fan stopped working after two years of use."
Pain Point 4: The need for moisture-proof fans in high-humidity environments
Phenomenon:The high humidity inside the freezer caused the fan PCB to become damp and corroded, and the bearings to rust.
root cause:The fan was not treated with moisture protection.
Solution:It uses a moisture-proof fan, has a PCB with conformal coating, and stainless steel bearings.

IV. Key Points of Heat Dissipation Design for Refrigeration Equipment
1. Condenser heat dissipation design
- Ensure there is sufficient ventilation space between the condenser and the fan.
- Regularly clean the dust buildup on the condenser fins to maintain heat dissipation efficiency.
- High-pressure fans are recommended to overcome fin resistance.
2. Low-temperature environment adaptability
- The fan needs to support low-temperature start-up at -25°C.
- Use low-temperature special lubricating oil to prevent solidification.
- The motor coils are made of low-temperature resistant materials.
3. Moisture-proof requirements
- The interior of the freezer requires moisture-proofing and PCB conformal coating.
- Bearings: Stainless steel bearings are selected to prevent rust.
- Defrost regularly to prevent ice buildup and airflow blockage.
V. Frequently Asked Questions (FAQ)
Q1: What should I do if the freezer fan stops turning at low temperatures?
A: We use a low-temperature start-up fan. The Fengheng low-temperature series uses special lubricating oil and supports low-temperature start-up at -25℃.
Q2: How do I determine if the condenser fan needs to be replaced?
A: When the compressor runs continuously for a long time and the cooling effect of the freezer decreases, it may be due to insufficient airflow from the condenser fan.
Q3: How long can a commercial refrigerator fan typically last?
A: Original factory AC oil-impregnated bearing fans typically last 2-3 years. Fengheng AC dual ball bearing fans can last 5-7 years.
Q4: How does the high humidity inside a freezer affect the fan?
A: High humidity can cause corrosion of the fan PCB and rust on the bearings. The WindConstant Moisture-Proof Edition uses conformal coating and stainless steel bearings for enhanced durability.
Q5: Do you support sample testing?
A: Free sample testing is available. We can provide original fan specifications and help you find the right upgrade solution.
