  • Principle of FP Laser Diode

    Principle of FP Laser Diode

    A Fabry–Pérot laser diode (FP laser diode) is the most common type of laser diode, having a laser resonator which is a Fabry–Pérot interferometer. This means that substantial light reflections occur at both ends, but not within the gain medium. FP laser cavity functions as a Fabry-Perot interferometer, which is based on the fundamental principle of multiple beam. A Fabry‑Perot (FP) laser is a common, cost‑efficient light source used within optical transceiver modules, particularly SFP modules. Its primary application is in low-data-rate short-distance transmission over distances of up to 20 kilometers.

  • Working principle of liquid-cooled lithium battery energy storage cabinet

    Working principle of liquid-cooled lithium battery energy storage cabinet

    In liquid-cooled energy storage systems, a cooling medium—usually a water-glycol mixture—is guided through cooling plates or channels close to the battery cells. Heat is absorbed directly at the source and transported to a heat exchanger. Rising power densities, more frequent charge and discharge cycles, and demanding operating conditions make precise temperature control indispensable. This is exactly where. However, in liquid-cooled battery cabinets, battery consistency control and battery balancing strategies are far more critical — and more complex — than in traditional air-cooled systems. It is because liquid cooling enables cells to have a more uniform temperature throughout the system whilst using less input energy, stopping overheating, maintaining safety, minimising degradation and. Aiming at the pain points and storage application scenarios of industrial and commercial energy, this paper proposes liquid cooling solutions.
