散热器是采暖系统的主要部件,根概有关统计资料,散热器的造价占整个系统造价的一半左右,而金属消耗量相当于整个系统的70％。因此,要想降低采暖系统造价,减少金属消耗,就应当改进我国现有的散热器。在铸铁散热器中,带肋片的长翼型及园翼型散热器,不仅传热系数比不带肋片的四桂散热器低,其金属热强度也比四柱散热器低。在散热器上布置肋片,一方面可以增加传热面积,但是更重要的还是为了提高金属热强度,降低散热器的金属消耗。我国现在生产的长翼型及园翼型散热器,根本起不到节
The radiator is the main component of the heating system. According to statistics, the cost of the radiator accounts for about half of the total system cost, and the metal consumption is equivalent to 70% of the entire system. Therefore, if we want to reduce the cost of heating systems and reduce metal consumption, we should improve our existing radiators. In cast iron radiators, long-winged and winged radiators with fins not only have lower heat transfer coefficients than Sigui radiators without fins, but also have lower metal thermal strength than four-column radiators. Arranging fins on the radiator can increase the heat transfer area on the one hand, but it is more important to increase the thermal strength of the metal and reduce the metal consumption of the radiator. The long-wing and garden-wing radiators currently produced in our country are simply not a festival.
