Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, specifically a multi-compartment heat exchange phase change thermal storage device. Background Technology

[0002] With the continuous growth of global energy demand and increasing environmental awareness, the utilization of renewable energy has become increasingly important. However, renewable energy sources such as solar and wind power are characterized by intermittency and instability, making energy storage a crucial element for their widespread application. Energy storage technology can not only solve the problem of the mismatch between time and space in energy supply, but also plays a significant role in improving energy efficiency and ensuring energy security. Among various energy storage technologies, thermal storage technology has attracted widespread attention due to its high energy density and relatively low cost.

[0003] Existing thermal energy storage technologies mainly include two methods: sensible heat storage and latent heat storage. Sensible heat storage stores heat by changing the temperature of the material; this method is simple and direct but has a low heat storage density. In contrast, latent heat storage utilizes the ability of phase change materials (PCMs) to absorb or release large amounts of latent heat during phase change processes, resulting in higher energy storage density and a narrower operating temperature range. Nevertheless, traditional single-compartment phase change thermal energy storage devices typically use a single type of PCM, making it difficult to adapt to temperature variations under different operating conditions. Furthermore, when PCM replacement or equipment maintenance is required, the entire system often needs to be shut down, increasing operating costs and time consumption.

[0004] Furthermore, traditional thermal storage devices also have certain limitations in terms of heat exchange efficiency. For example, during the heat exchange process, problems such as low heat exchange efficiency due to unreasonable PCM encapsulation methods exist. These problems limit the overall performance of the thermal storage device, especially in terms of efficient utilization of renewable energy. Therefore, developing a high-efficiency thermal storage device that can effectively meet the needs of different temperature ranges and is easy to maintain has become one of the key research directions. Therefore, a novel design that can solve these problems is urgently needed. Thus, this utility model proposes a multi-compartment heat exchange phase change thermal storage device.
