In scenarios such as security surveillance, enterprise data backup, and industrial production recording, DVRs (digital video recorders) are core devices for real-time video data storage and playback. Their internal hard disk arrays, main control chips, and power modules must operate 24/7. The high-speed rotation of the hard disks and the chip data processing generate continuous heat. Furthermore, the compact design of the devices leaves limited space for heat dissipation. If this heat cannot be dissipated promptly, it will not only reduce hard disk read and write speeds and cause data storage errors, but may also cause the device to crash or even physical damage to the hard disk, resulting in the loss of important footage. The Xingdong DC Axial Fan 3510, with its compact size, efficient energy-saving heat dissipation, and low noise performance, precisely addresses DVR cooling challenges. The Xingdong DC Axial Fan 3510 provides a solid foundation for stable data storage.

I. DVR Heat Dissipation Pain Points

Densely Dense Components and Concentrated Heat Generation: DVRs typically integrate 2-8 hard disks, a high-performance main control chip, and a power module. The simultaneous operation of multiple components results in high heat generation per unit area, creating localized high-temperature zones within the confined space, making heat accumulation difficult to dissipate naturally.

High temperatures threaten data security: The normal operating temperature of a hard drive is 25-35°C. Every 10°C increase in temperature shortens its lifespan by approximately 50%. High temperatures can also cause read and write errors in the hard drive head, resulting in video freezes and frame drops. High temperatures can also disrupt the computing stability of the main control chip, potentially causing the DVR to automatically reboot and interrupt recording, creating a risk of security monitoring blind spots.

The conflict between the need for quiet operation and heat dissipation: DVRs are often installed in noise-sensitive environments such as offices, computer rooms, and monitoring rooms. While traditional fans can meet cooling requirements, their excessive operating noise (over 30dB) can disrupt work and rest. Fanless designs cannot handle long-term high-load heat dissipation, creating a "heat dissipation-quiet" dilemma.

II. Core Advantages of the Xingdong DC Axial Fan 3510

(I) Precise Dimensions, Fitting into the Tight Spaces of DVRs

Compact and Flexible Fit: Its ultra-thin dimensions of 35×35×10mm allow it to be precisely integrated into the cooling vents on the side or back of the DVR without altering the internal hard drive and motherboard layout. This allows for efficient placement within limited space, without occupying hard drive mounting or wiring space.

Thin and Lightweight Design: Its thickness of 10mm, equivalent to two coins stacked together, does not increase the overall thickness of the DVR, ensuring it can be easily placed in cabinets, desktop stands, and other installation scenarios. It is compatible with the standardized design of most DVRs.

(II) High Energy Efficiency + Powerful Wind for Dual-Action Temperature Control

Intelligent Speed ​​Control for Power Saving: This feature optimizes energy efficiency and supports PWM speed regulation, dynamically adjusting fan speed based on the DVR's internal temperature. It operates at low speeds during low loads, maintaining efficient heat dissipation while reducing power consumption. It automatically increases speed during high loads to prevent heat accumulation, achieving both energy saving and temperature control. Strong Air Penetration for Rapid Heat Dissipation: A high-speed design and a pressurized structure enhance airflow penetration, delivering 5.06-6.30 CFM and a stable air pressure of 1.28-3.68 mmH₂O. This allows it to quickly penetrate gaps between DVR components, extracting high-temperature air generated by hard drives and chips, thereby preventing read/write failures and computational delays caused by high temperatures.

(III) Noise Reduction and Quietness, Suitable for Sensitive Environments

Low-Noise Structural Design: Through fluid dynamics optimization of the impeller design, operating noise is strictly controlled below 20.3 dBA. In actual operation, the noise level is close to the background noise level of a library environment. When used in offices, monitoring rooms, and other environments, it is not noticeably noisy, perfectly balancing the need for quiet operation with heat dissipation efficiency.

Smooth Start and Stop with Anti-Shock: PWM speed regulation enables smooth start and stop, slowly increasing the speed from 0 to the set value, avoiding the noise impact caused by the "instant start" of traditional fans. It also reduces the impact of motor starting current on the DVR power module, extending the power supply life.

(IV) Durability + Safety Protection to Meet Long-Term Operation Requirements

Strong Durability Guarantee: Utilizing a pure copper coil motor with excellent electrical conductivity, it reduces energy loss while significantly improving durability, enabling continuous DVR operation. Bearing lifespan reaches 80,000 hours, eliminating the need for frequent maintenance and replacement.

Top-Level Protection and Interference Prevention: IP68-rated water and dust resistance effectively blocks dust and moisture from the computer room environment.
