采暖用能是能量消耗的一个重要方面,北欧国家的采暖用能占总能量消耗的40％以上。采暖系统的技术经济指标在很大程度上取决于散热器的形式和构造。目前国外正对此进行多方面的研究工作,希望研制出一种传热效率高、材料耗量少、经久耐用、制造安装简单且又经济美观的新型散热器结构。铸铁散热器铸铁散热器曾长期被肯定为简单可靠的散热装置,应用很广泛。它的主要优点是,结构比较简单、经久耐用、防腐蚀性能好,以及能使房间的散热量较为稳定。但是它的突出缺点是,金属耗量大、制造安装和运输等劳动繁重、外形结构较笨重。随着建筑现代化、工业化的发展,铸铁散热器正逐步
Heating energy is an important aspect of energy consumption. Heating in the Nordic countries can account for over 40% of total energy consumption. The technical and economic indicators of the heating system depend to a large extent on the form and construction of the radiator. At present, foreign countries are conducting many research work in this regard and hope to develop a new type of heat sink structure with high heat transfer efficiency, low material consumption, durability, simple and economical manufacturing and installation. Cast iron radiator radiator has long been recognized as a simple and reliable heat sink, widely used. Its main advantage is that the structure is relatively simple, durable, good corrosion resistance, and can make the heat dissipation of the room more stable. However, its outstanding disadvantages are the heavy metal consumption, labor-intensive manufacturing, installation, and transportation, and the heavy and bulky exterior structure. With the development of modernization and industrialization, cast iron radiators are gradually
