On a scorching summer day, when you bring home a bag full of ice cream from the supermarket, have you ever wondered how these delicate frozen foods managed to stay safe during transportation? When you open your home freezer to take out frozen meat only to find it covered in frost, have you ever realized the technological intrigue behind the scenes? Today, we'll explore the core DC axial-flow fan 1238, the core of cold chain equipment, and reveal how the Xingdong DC axial-flow fan 1238 safeguards freshness in extreme cold environments.

The Test of Cold Chain Equipment
Modern refrigerators may appear simple metal boxes, but they actually house a sophisticated ecosystem: The compressor continuously generates a large amount of heat, and the significant temperature difference between the inner container and the outside world causes condensation to accumulate rapidly. Various electronic controllers are constantly under the dual pressure of low temperature and humidity.
Traditional cooling solutions encounter three major challenges: ① Ordinary bearing grease solidifies and sticks when cold; ② Metal components contract and deform due to heat and cold; and ③ Moisture intrusion causes electrical shorts. This is the root cause of many refrigerators experiencing increasing power consumption and requiring three-year maintenance. The Xingdong DC Axial Fan 1238's Breakthrough
Designed for extreme environments, this specialized fan uses cutting-edge technology to rewrite industry rules:

Ultra-Low-Temperature Capability: The DC Axial Fan 1238 maintains smooth operation in temperatures as low as -40°C. Laboratory verification shows speed fluctuations of less than 5% after 72 hours of continuous operation, far exceeding the industry standard of ±15%.

Anti-Frost Armor Design: The DC Axial Fan 1238's blades are coated with a hydrophobic coating, and a unique vortex water-guiding structure effectively directs condensate outward, eliminating the "frozen blades" phenomenon common with traditional fans.

Military-Grade Protection: The DC Axial Fan 1238's anodized body increases corrosion resistance by four times. Its IP68-rated waterproof and dustproof design easily withstands the impact of moisture from frequent cold storage door openings.

Encoded for Long Life: The DC Axial Fan 1238 utilizes imported bearings and a double-layer seal structure, resulting in a lifespan of up to 80,000 hours.

Witness the miracle in real-world scenarios.

In field tests at a well-known cold chain logistics company, a vehicle-mounted freezer equipped with the DC 1238 axial-flow fan achieved an astonishing record: after 12 hours of continuous driving in -30°C temperatures on the Northeast Plain, the cargo compartment temperature remained consistently within the ideal range of -18±1°C. In the humid and hot southern regions, the device successfully withstood 95% humidity without showing any signs of mold on the internal circuit boards. Even more impressively, a seafood processing plant used this fan in its quick-freezing tunnel, reducing equipment failure rates by 76%.

For ordinary families, this reliability translates into a tangible improvement in their quality of life: no more worrying about freezer malfunctions during Spring Festival stockpiling, no more hassles with repeated defrosting, and even unexpected energy savings—real-world data shows that optimized freezers can reduce monthly electricity bills by 25 kilowatt-hours.

In an era where freshness is synonymous with health, excellent industrial design often hides in unseen places. Next time you enjoy a cold beer, think about the countless ingenious products like the Xingdong DC axial-flow fan 1238 that provide the freshness-preserving defenses of modern life.

Due to their wide adaptability in performance and operating voltage (e.g., 12/24V), DC axial-flow cooling fans are suitable for a wide range of electronic devices, such as power supplies, smart appliances, racks, cabinets, and various industrial equipment. When selecting a fan, we recommend choosing the appropriate model and specifications based on the device's cooling requirements, space constraints, and the fan's quietness requirements.
