I. Four Core Pain Points of Instrument and Meter Heat Dissipation
Pain Point 1: The stringent requirements for low vibration in precision instruments
Phenomenon:The fan vibration is transmitted to the measurement circuit, causing the measurement data to fluctuate and become inaccurate.
root cause:The fan is not dynamically balanced and vibrates excessively.
Industry data:Precision instruments typically require fan vibration speeds of ≤1.0 mm/s.
Pain Point 2: The requirement for low noise in the laboratory environment
Phenomenon:Noise from laboratory equipment fans can affect researchers' concentration.
root cause:Small fans require high speeds to achieve the desired airflow, which in turn leads to high noise levels.
User feedback:Laboratory staff complained that "the instrument fans are buzzing so loudly that they give me a headache after listening to them for a long time."
Pain Point 3: Reliability Requirements for Long-Term Continuous Operation
Phenomenon:Online monitoring instruments and aging testing equipment operate year-round, and insufficient fan lifespan can cause equipment downtime.
root cause:Cheap oil-bearing fans have a lifespan of only 10,000 to 20,000 hours
Industry feedback:Instrument manufacturers report that "fan failure is one of the main reasons for returns for repair."
Pain Point 4: The requirement for stable airflow in high-precision temperature control
Phenomenon:Large temperature fluctuations in temperature control equipment such as PCR instruments and incubators can affect experimental results.
root cause:Unstable fan airflow leads to fluctuations in heat dissipation efficiency.
Industry Standards:Temperature control equipment requires fans to have PWM speed regulation function to stably control airflow.

IV. Key Points of Instrument and Meter Heat Dissipation Design
1. Low vibration design
- High-precision dynamically balanced fans are selected (vibration ≤1.0mm/s).
- Use shock-absorbing pads/shocking feet for installation to reduce vibration transmission.
- Avoid the fan and case resonance point coinciding.
2. Low noise design
- Laboratory environment: ≤25dBA, hydraulic bearings or FDB bearings should be selected.
- Office environment: ≤30dBA
- A large-size, low-speed fan can be used to replace a small-size, high-speed fan.
3. Temperature control accuracy requirements
- A PWM speed-controlled fan is selected to achieve closed-loop temperature control.
- Temperature sensor feedback controls fan speed
- Fan speed stability: within ±5%
V. Frequently Asked Questions (FAQ)
Q1: What are the requirements for fan vibration in precision instruments?
A: Vibration velocity is typically required to be ≤1.0mm/s. The Fengheng low-vibration series can achieve this.<0.8mm/s, does not affect measurement accuracy.
Q2: What are the noise standards for laboratory instruments?
A: Generally, the noise level is required to be ≤25dBA, but the noise level of the Fengheng hydraulic bearing series can be controlled below 22dBA.
Q3: Why do temperature control devices such as PCR instruments use PWM fans?
A: The PWM fan can precisely control the speed, and together with the temperature sensor, it can achieve closed-loop temperature control, ensuring the repeatability of experimental results.
Q4: How long can the fan of an instrument typically last?
A: Original factory oil-impregnated bearing fans typically last 1-2 years. Fengheng dual ball bearing fans can last 5-7 years, matching the instrument's lifespan.
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.
