一项具有国内先进水平的新技术,于3月25日在长沙散热器厂,通过了省级“星火计划”验收。这次验收的新技术——TZ型椭园管采暖散热器,是由长沙市南区的区属集体企业——长沙散热器厂研制和开发的。该厂原来生产的产品,系四、五十年代仿苏老式散热器,耗能大、效果低。新开发的散热器打破了传统的设计,将原散热器的园形绕片管改 A new technology with advanced domestic standards was passed at the Changsha Radiator Factory on March 25 and passed the provincial “Spark Plan” acceptance. The new technology of this acceptance, the TZ-type elliptical tube heating radiator, was developed and developed by the Changsha Radiator Factory, a collective enterprise of the Southern District of Changsha City. The original production of the plant was an old Soviet-style radiator in the 40s and 50s, which was energy-intensive and ineffective. The newly developed radiator breaks the traditional design and changes the shape of the original radiator around the tube.
