CT Scanner Cooling Under 75G Centrifugal Force: SANYO DENKI San Ace G Proof Fan Solution

How Can CT Scanner Cooling Handle 75G Centrifugal Force Generated by High-Speed Rotation? SANYO DENKI San Ace G Proof Fan Provides a Highly Reliable Cooling Solution

Introduction: Cooling Reliability Becomes a Key Challenge for Advanced CT Scanners

With the rapid development of medical imaging technology, CT scanners (Computed Tomography scanners) have become essential diagnostic devices in modern hospitals. As CT systems continue to evolve toward higher scanning speeds, higher resolution, and more advanced functions, the reliability requirements for internal components have become increasingly demanding.

During CT scanning, the X-ray tube rotates at high speed while continuously generating X-rays to capture detailed images. This process produces a significant amount of heat inside the equipment. Therefore, an efficient CT scanner cooling solution is essential to maintain stable operation.

However, the high-speed rotating structure inside CT scanners creates an extremely challenging environment for cooling fans. The centrifugal force generated during rotation can place severe mechanical stress on conventional fans, causing failures and increasing maintenance requirements.

To solve this problem, SANYO DENKI San Ace developed the G Proof Fan, a specialized cooling fan designed for high G-force environments. With the ability to withstand up to 75G centrifugal acceleration, the G Proof Fan provides a highly reliable cooling solution for CT scanners and other equipment exposed to strong mechanical forces.

1. Why CT Scanners Require Highly Reliable Cooling Solutions

1.1 Continuous Operation Generates Significant Heat

A CT scanner uses X-rays to capture cross-sectional images of the human body. During operation:

• The X-ray source continuously generates radiation;

• High-power electronic components produce heat;

• Internal modules experience temperature increases;

• Effective forced-air cooling becomes necessary.

Without sufficient cooling performance, excessive heat may cause:

For medical imaging equipment, cooling reliability directly affects the overall performance and availability of the system.

2. The Challenge of Cooling CT Scanners Under High Centrifugal Force

Unlike conventional industrial equipment, CT scanners contain rotating structures that operate at high speed.

During rotation, cooling fans installed inside the scanner may be exposed to strong centrifugal forces.

The continuous mechanical stress caused by high-speed rotation can lead to:

• Impeller deformation;

• Rotor damage;

• Component loosening;

• Abnormal noise;

• Reduced airflow performance;

• Fan failure.

For medical equipment manufacturers, cooling fans must not only provide sufficient airflow but also maintain long-term mechanical reliability under extreme operating conditions.

3. Why Conventional Fans May Fail in a 75G Environment

Most standard cooling fans are designed for fixed installation environments, such as:

• Servers;

• Industrial control equipment;

• Communication systems;

• Power supplies.

These applications mainly require resistance against:

• Vibration;

• Temperature changes;

• Continuous operation.

However, CT scanners create a much more demanding environment.

The rotating gantry structure generates high centrifugal acceleration, placing additional stress on fan components.

If a conventional fan is used in such an environment, potential problems include:

• Structural fatigue;

• Impeller separation;

• Rotor deformation;

• Increased maintenance frequency.

To address these challenges, SANYO DENKI San Ace G Proof Fan was developed specifically for high G-force applications.

4. SANYO DENKI San Ace G Proof Fan: A Solution for 75G High-Acceleration Environments

4.1 Withstands Up to 75G Acceleration

The key feature of the G Proof Fan is its ability to operate normally under extremely high acceleration conditions.

Performance specifications:

• Maximum withstand acceleration: 75G

• Equivalent acceleration: 735 m/s²

• Tested operation time: 1,000 hours

• Operates normally in X, Y, and Z axis directions

This capability enables reliable cooling in equipment where conventional fans cannot maintain stable operation.

5. Structural Design Behind the High G-Force Resistance

5.1 High-Rigidity Aluminum Frame

The SANYO DENKI San Ace G Proof Fan adopts a high-rigidity aluminum frame structure.

This design provides:

✔ Increased mechanical strength
✔ Reduced deformation during high-speed rotation
✔ Improved vibration resistance
✔ Enhanced long-term reliability

The reinforced frame protects the internal motor structure from excessive mechanical stress in rotating environments.

5.2 One-Piece Molded Impeller and Rotor Cover Structure

A conventional fan generally consists of separate components:

Impeller
   ↓
Connection Structure
   ↓
Rotor

During high-speed rotation, the connection areas experience significant centrifugal stress, which may result in fatigue or loosening over time.

The G Proof Fan adopts a:

One-piece molded structure combining the impeller and rotor cover

This structure improves:

• Bonding strength between components;

• Resistance against centrifugal forces;

• Overall mechanical durability.

As a result, the fan can maintain stable operation even under severe rotating conditions.

6. Benefits of Using SANYO DENKI San Ace G Proof Fan in CT Scanner Cooling

By adopting a high G-force resistant cooling fan, CT scanner manufacturers can achieve improved system reliability.

The use of G Proof Fan helps reduce:

• Fan failure risks;

• Equipment downtime;

• Maintenance frequency;

• Total operating costs.

7. PWM Speed Control for Efficient CT Scanner Cooling

In addition to its high mechanical strength, selected SANYO DENKI San Ace G Proof Fans support PWM speed control.

PWM control enables:

• Remote fan speed adjustment;

• Automatic cooling optimization;

• Reduced noise during low-load operation;

• Lower power consumption.

Advantages include:

✔ Improved thermal management
✔ Reduced equipment noise
✔ Optimized energy efficiency
✔ Extended fan service life

For medical imaging systems requiring precise thermal control, intelligent fan management provides additional reliability.

8. High-Reliability Cooling Fans for Medical Equipment Applications

Medical equipment requires extremely stable operation compared with ordinary industrial devices.

Applications such as:

• CT scanners;

• X-ray imaging systems;

• Medical diagnostic equipment;

• Precision healthcare devices;

require cooling solutions that can operate reliably under demanding conditions.

A cooling fan is not simply an airflow component. It is a critical part of system reliability.

Choosing the right fan technology helps improve:

• Equipment stability;

• Operational efficiency;

• Maintenance performance;

• Product lifetime.
