散热器是安装在采暖用户内一种散放热量的设备。热媒(蒸汽或热水)通过管道输送到散热器中,由散热器将热量散放到采暖房间,使室内温度升高,以补偿建筑物的热损耗,达到采暖的目的。散热器的散热过程为:热媒在散热器内通过对流换热方式把热量传给内壁,内壁靠金属传导换热把热量传给外壁,外壁再靠对流换热 Radiator is a kind of heat dissipation equipment installed in heating users. The heat medium (steam or hot water) is transported into the radiator through the pipeline. The heat is dissipated by the radiator to the heating room, so that the indoor temperature is increased to compensate for the heat loss of the building and achieve the purpose of heating. Radiator cooling process: the heat medium in the radiator through the convection heat transfer to the inner wall, the inner wall of the metal conduction heat transfer to the outer wall, the outer wall and then rely on convection heat transfer
