By the Hunan Institute of Electronics and Changsha refrigerator factory co-developed DSWX-1 refrigerator inspection line microcomputer detection system has been identified. By the Guangdong Shunde Xingtan Huashan Electric Factory digestion and introduction of technology to produce automotive air conditioning cooling fan through the identification and put into production. Lv Gang engineers in Henan Province developed a highly efficient shell and tube heat exchanger, and can transform the existing tube bundle can be extracted from the heat exchanger, generally do not have to replace the equipment, the transformation cycle of 2 to 5 days, the total heat transfer coefficient can be improved after the general increase of 20 %. The patented technology for the transfer.
