Modular frame bearing energy storage device

Abstract

The invention discloses a modular frame bearing energy storage device which comprises a box body, a heat preservation structure, a thermal storage device, a phase-change energy storage unit, an outlet pipe and an inlet pipe. The thermal storage device is arranged in the box body. The heat preservation structure is arranged between the exterior of the thermal storage device and the inner surface of the box body. The box body is a closed structure provided with a plurality of output interfaces and a plurality of input interfaces. The heat preservation structure can be detachably separated from the box body. One end of the inlet pipe and one end of the output pipe are in linkage with the thermal storage device through the box body and the heat preservation structure, and the other end of the inlet pipe and the other end of the outlet pipe are connected with an energy supply device and an energy consumption device respectively. The phase-change energy storage unit and the box body are connected and are inserted into the thermal storage device, the modular design is adopted, and the device is convenient to replace. The modular frame bearing energy storage device can be combined and applied. The phase-change energy storage unit is convenient to replace, simple in structure, convenient to operate, safe and reliable, and convenient to transport.

Description

Technical field [0001] The invention relates to a phase change heat storage device, belonging to the field of energy conservation and environmental protection, and in particular to a modular combined energy storage device with a full load-bearing structure that facilitates the modular replacement of a phase change energy storage unit. [0002] Background technique [0003] In today's society, energy shortages and environmental pollution have become important problems facing us. The development and utilization of renewable energy has important practical significance for energy conservation and environmental protection. Phase change energy storage technology uses phase change materials to absorb or release a large amount of heat to achieve the purpose of energy storage. It is an effective way to alleviate the mismatch between energy supply and demand in terms of time, intensity and location. [0004] "Heat storage" technology is an important part of the field of "energy storage". Th...

Problems solved by technology

[0008] In practical applications, the energy storage device has high requirements on the transportation road conditions and on-site hoisting conditions. Once a failure occurs during transportation or subsequent use, it can only be maintained on the whole machine or returned to the factory for repair, and the transportation and maintenance costs are relatively high.
