Description

Technical Field

[0001] This utility model relates to the field of USB flash drives, and more particularly to a USB flash drive with excellent heat dissipation. Background Technology

[0002] A USB flash drive is a convenient portable storage device that uses flash memory technology to store data. It connects to a computer or other devices via a USB interface and is commonly used for data transfer, backup, and storage. The advantages of a USB flash drive include its small size, fast read speed, durability, and the fact that it does not require an external power supply.

[0003] Existing technologies, such as the utility model patent with announcement number CN222600225U, disclose a dustproof USB flash drive. This patent uses a dustproof box, with a pull rod slidably connected to the inner wall of the dustproof box. One end of the pull rod is hooked and connected to a limit rope. One end of the dustproof box is fixed to an ejector spring. The USB flash drive body is rotatably connected between the inner walls of the pull rod and the dustproof box via a pivot. A lock hole is opened at the top of the dustproof box, and a pressing groove is opened at the bottom of the inner wall of the lock hole. A pressure plate is slidably connected in the pressing groove. This utility model, by designing a USB flash drive dustproof device composed of a dustproof box, a pressing button, a pull rod, an ejector spring, and a limit rope, can achieve isolated storage of the USB flash drive, preventing dust from entering the internal circuitry through the metal plug of the USB flash drive and affecting its operation. At the same time, the device also provides drop protection. Compared with the traditional USB flash drive plug structure, the integrated structure of this device can prevent users from discarding it at will, providing a stable protection function.

[0004] The inventors discovered in daily use that when existing USB flash drives operate at high temperatures, the internal chips and storage media may overheat, causing read or write speeds to slow down, affecting performance and response time. Furthermore, prolonged use in high-temperature environments may damage the internal circuitry, storage chips, or controllers of the USB flash drive, reducing the device's lifespan or even causing permanent malfunctions. Overheating may also cause instability in the operation of the internal storage devices of the USB flash drive, increasing the risk of data loss. In particular, during data transmission, excessively high temperatures may lead to write errors or corrupted stored data.
