Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0031] Such as figure 1 and figure 2 As shown, the present invention is a hydride heat storage system that uses heat radiation to dissipate heat. It includes a heat exchange tank 1 and a heat storage reactor 2 installed in the heat exchange tank 1. The heat exchange tank 1 is respectively equipped with a The inflow port 9 and the outflow port 10 where the medium enters and exits, and the connection between the inflow port 9 and the outflow port 10 is arranged; the hydrogen valve 8 for the circulation of hydrogen gas is fixedly connected between the heat exchange tank 1 and the heat storage reactor 2, and the hydrogen gas The valve 8 is installed with hydrogen gas discharged / absorbed for hydrogen storage when absorbing and releasing heat. The end of the hydrogen valve 8 away from the heat storage reactor 2 is fixedly connected with a hydrogen...

Abstract

The invention relates to a hydride heat storage system for dissipating heat by thermal radiation. The system comprises a heat exchange tank and a heat storage reactor mounted in the heat exchange tank. The heat exchange tank is separately provided with a flow inlet and a flow outlet where a heat exchange medium comes in and goes out, and the flow inlet and the flow outlet communicate; a hydrogen valve where hydrogen circulates is arranged between the heat exchange tank and the heat storage reactor; and a thermal radiation coating is arranged on the inner wall of the heat storage reactor, and ametal hydride and thermal radiation enhanced particles mixed with each other are placed in the heat storage reactor. Heat in the heat storage reactor is mainly transferred by thermal radiation between the thermal radiation coating and the thermal radiation enhanced particles. By adopting the technical scheme, the hydride heat storage system is simple in structure and economical and practical, andthe heat exchange performance and the heat storage efficiency of the system are improved.

Description

technical field [0001] The invention relates to the technical field of solar thermal energy storage, in particular to a hydride heat storage system and its application using thermal radiation to dissipate heat. Background technique [0002] Since the beginning of the 21st century, energy crises and environmental degradation have occurred worldwide, forcing human society to develop various renewable and clean energy sources. Solar energy is an abundant renewable energy source that has attracted extensive attention from researchers.
