Do you struggle with keeping your electrical enclosures or control cabinets cool? Many face challenges like hot spots, poor air movement, and harsh environments.
- Inadequate air circulation often creates isolated temperature build-up, which can cause system malfunctions and shorten component life.
- Poor ventilation is common, especially in industrial spaces where panels sit in tight or poorly ventilated areas.
- Dust and humidity can lead to condensation, raising the risk of short circuits and damaging key components.
Choosing the right custom cooling fans helps you prevent these issues and protect your equipment.
Key Takeaways
- Understand your cooling needs by calculating the heat load from your equipment. This helps prevent overheating and ensures safe operation.
- Consider the size and mounting options of your enclosure. Proper fan placement is crucial for effective airflow and maintenance.
- Select fans based on environmental conditions. Choose models with appropriate IP ratings to protect against dust and moisture.
- Calculate airflow requirements using specific formulas. Ensure your fan can handle the necessary flow rate and static pressure for optimal performance.
- Prioritize reliability and maintenance. Regular inspections and cleaning extend the lifespan of your cooling fans and protect your investment.
Cooling Needs
When you select a custom cooling fan, you first need to understand your system’s cooling needs. This step helps you avoid overheating and keeps your equipment running safely.
Heat Load
Start by figuring out how much heat your enclosure produces. Heat load comes from two main sources:
- Internal heat load: This is the heat created by the electronics inside your enclosure.
- External heat load: This is the heat gained or lost through the enclosure walls, which depends on where you place the enclosure.
You can estimate your total cooling requirements by following these steps:
- Check the power consumption of all components inside the enclosure. About 10–15% of this power turns into heat.
- Measure the temperature difference between the inside and outside of the enclosure.
- Add up the known heat generation of each device (in watts or BTU/h).
Different environments need different NEMA ratings. For example, outdoor, washdown, or hazardous locations require special protection. Linkwell’s fan filter units and electrical enclosure fans work well in many industrial settings, helping you manage both internal and external heat loads.
Airflow & Temperature
Once you know your heat load, you need to set your airflow and temperature targets. Proper airflow ensures your system stays within safe temperature limits. You can calculate airflow using these formulas:
- For degrees Fahrenheit:
Airflow (CFM) = BTU/hr / (1.08 × ΔT°F) - For degrees Celsius:
Airflow (CFM) = BTU/hr / (1.95 × ΔT°C)
A typical temperature rise is 10°C or 18°F. Add a 25% safety margin to your total cooling requirements for extra protection.
Tip: Many electrical components, like power supplies and drives, operate safely up to 60°C (140°F). Devices that generate more heat need careful thermal management.
Here are common temperature thresholds for electrical equipment:
| Temperature Rating (T-rating) | Description |
|---|---|
| T1 (up to 450 °C) | High ignition risk environments |
| T2 (up to 300 °C) | Many industrial applications |
| T3 (up to 200 °C) | Moderate ignition risk |
| T4 (up to 135 °C) | Lower ignition risk |
| T5 (up to 100 °C) | Less hazardous environments |
| T6 (up to 85 °C) | Very low ignition risk environments |
When you choose a Linkwell fan filter unit or electrical enclosure fan, you match your cooling capacity to your system’s needs. This approach helps you meet safety standards and keeps your equipment reliable.
System Constraints
Space & Mounting
When you choose a cooling fan, you must consider the size and shape of your enclosure. The available space inside the cabinet determines where you can mount the fan and how much airflow you can achieve. A compact enclosure limits your options and requires careful planning to avoid blocking airflow or making maintenance difficult.
Here is a table showing standard space constraints for industrial enclosures:
| Description | Dimensions (W x H x D) |
|---|---|
| Maximum internal space for devices | 413 mm x 470 mm x 152 mm |
| Maximum allowable space (brackets/cables) | 470 mm x 470 mm x 152 mm |
| Primary internal PC mounting plate | 356 mm x 457 mm |
| Secondary service panel maximum size | 381 mm x 368 mm x 152 mm |
You should also think about mounting options. The way you install the fan affects how well it cools your equipment. For example:
- Wall-mounted exhaust fans pull air toward them, which can create dead zones.
- Wall-mounted intake fans push air into the enclosure and may disrupt natural airflow.
- Roof-mounted exhaust fans help remove hot air by promoting vertical airflow.
Tip: If your PC has an integrated cooling fan, you may not need an internal circulating fan. If you skip the internal fan, mount the PC as low as possible in the enclosure for better cooling.
Linkwell offers fan filter units and electrical enclosure fans that fit various mounting styles. You can select models designed for tight spaces or larger cabinets, ensuring proper airflow and easy installation.
Environment
The environment around your enclosure plays a big role in fan performance. High temperatures, humidity, and corrosive substances can damage fan components and reduce their lifespan. You need fans built with materials that withstand these conditions.
| Environmental Factor | Impact on Fan Performance |
|---|---|
| Temperature | Fans must handle high heat without losing efficiency. |
| Humidity | Moisture can shorten the life of fan motors and bearings. |
| Corrosive Substances | Fans need corrosion-resistant materials to keep working in harsh environments. |
IP ratings help you choose fans that resist dust and water. The first digit of the IP rating shows protection against solids, and the second digit shows protection against liquids. For example, an IP55 rating means the fan has limited dust ingress and can handle low-pressure water jets. This rating improves reliability in dusty or moist settings.
Linkwell’s IP-rated fan filter units and weatherproof enclosure fans give you peace of mind. You can trust these products to perform well in challenging environments, keeping your equipment safe and cool.
Calculate Airflow
Use Equations
You need to calculate the required flow rate and static pressure before choosing a cooling fan. Start by estimating the heat produced inside your enclosure. Use the following formula to find the necessary flow rate in cubic feet per minute (CFM):
Airflow (CFM) = BTU/hr / (1.08 × ΔT°F)
This equation helps you determine how much air you need to move to keep your equipment cool. If you measure in metric units, use:
Airflow (m³/h) = Qv / (F × ssT)
Here is a table that explains the variables:
| Variable | Description |
|---|---|
| V | Required volumetric air flow (m³/h) |
| F | Volume (m³) of air needed per °C change for each Watt-hour of heat transfer |
| Qv | Heat generated by equipment |
| ssT | Difference between internal requirement and external ambient |
You must also consider static pressure. Static pressure measures the resistance to airflow caused by filters, heatsinks, or tight spaces. High static pressure fans push air through obstacles, keeping the flow rate steady. Use this equation to relate heat transfer and flow rate:
- Q̇ = 1.0746 × ΔT × ṁ
- Q̇: Rate of heat transfer
- ΔT: Temperature difference
- ṁ: Flow rate of air (CFM)
Tip: Always check the static pressure rating of your fan. If your enclosure uses filters or has dense wiring, you need a fan that can overcome higher static pressure.
