Phase-change energy-storage radiator

Abstract

The invention relates to a phase-change energy-storage radiator, and belongs to the field of new type energy, energy conservation and environmental protection. The phase-change energy-storage radiator is used for storage and controlled releasing of heat energy in multiple grades. The phase-change energy-storage radiator comprises an outer heat preservation box and an energy-storage unit; a natural convection radiating runner is formed between the energy-storage unit and a heat preservation shell; and the natural convection radiating runner is controlled to be opened and closed, and therefore timing accumulated storage and releasing of the energy can be achieved. Heat insulation and energy storage can be completely achieved in the energy storage process of the phase-change energy-storage radiator, and meanwhile radiating can be controlled in the storage process. The device is large in energy-storage volume and small in size. According to a specially developed and allocated mixed chlorinated paraffin low-temperature phase-change energy-storage material, the energy-storage temperature scope is appropriate, the material is non-toxic and free of chemical changes, the energy-storage temperature scope and the heat release amount are not changed after repeated utilization, undercooling and overheating phenomena are avoided, and both the physical and chemical property and the reliability are excellent.

Description

technical field [0001] The invention relates to a phase-change energy storage radiator, which belongs to the field of new energy, energy saving and environmental protection, and is used for storage and controllable release of heat energy of various grades. Background technique [0002] For a long time, my country's energy consumption has been dominated by coal, oil and natural gas. The national exploitation and use of coal resources and the excessive reliance on fossil energy consumption in China's economic development will inevitably affect energy security. At the same time, the development and utilization of fossil energy have also directly caused huge damage to the environment. Influence. In the process of China's industrialization, energy has always been the bottleneck restricting the sustainable growth of China's economy, and energy conservation and emission reduction have gradually become the core concept of energy development and utilization in macro-control. Over the...
