制御盤向けファン選定の基礎知識

The devices and components inside the control panel generate heat during operation.
If left unattended, overheating can lead to reduced performance and even breakdowns, so selecting an appropriate cooling fan is important.

We have picked out some key points and are introducing them here. For more information, please download the free document that summarizes basic knowledge in an easy-to-understand manner and make use of it.

1. Calculating the amount of heat generated inside the control panel

The most important thing when selecting a fan is to accurately understand the amount of heat generated inside the control panel.
Calculate the heat generated by each device or equipment and add it all together.
Since the amount of heat generated varies depending on the power consumption and operating conditions of the equipment, a detailed study will be conducted based on catalog data and actual measured values.

2. Check the installation environment

The control panel installation environment also affects fan selection.
Factors such as outside temperature and humidity, ventilation of the installation location, and the presence of dust and oil will affect cooling performance and lifespan, so be sure to select an appropriate model based on the environmental conditions.

3. Fan air volume and static pressure

When selecting a fan, the main indicators of fan performance, air volume and static pressure, are also important.
A fan's air volume is the amount of air blown out, and static pressure is the force with which the air pushes against the surrounding area when it is stationary.
When cooling a large space such as a control panel, it is important to select a fan with excellent airflow and static pressure.

4. Fan placement

The location where the fan is installed also has a significant impact on cooling efficiency, so it is important when selecting a fan.
To efficiently exhaust hot air from inside the control panel, the fan layout must be designed appropriately.
When using multiple fans, it is important to position them so that their airflow does not interfere with each other.

5. Fan reliability and maintainability

Fans often operate for long periods of time, so it is important to choose products that are highly reliable.
Particularly for equipment that operates 24 hours a day or for important control systems, it is important to select fans that are highly durable and have a long life span to reduce the frequency of maintenance.

6. Consideration of noise and power consumption

If the control panel is installed close to a work environment, noise can be a problem, so it is necessary to select a fan that is quiet.
Furthermore, lower power consumption by the fan itself also leads to lower power consumption for the entire device.
