我厂研制的SSR-1型驾驶室取暖用新式加热器首先用于上海建筑机械厂生产的R942型液压挖掘机,也可用于其它工程机械。这种加热器的关键部分是热交换器,其所用铝合金扁管内面有13个6.1×4.29mm的长方形孔,扁管外面具有密集的翅片,长1.2m,宽0.98m,弯曲六段成形。联邦德国利勃赫尔公司采用特殊设备热挤压法制造。我们经过大量调研。因地制宜,在保证原机性能的情况下作了改型设计,并于1988年10月通过部级鉴定,
The SSR-1 type heating heater used in the cab developed by our factory was first used in the R942 hydraulic excavator produced by the Shanghai Construction Machinery Plant and can also be used in other construction machinery. The key part of this type of heater is the heat exchanger. There are 13 rectangular holes of 6.1 x 4.29mm in the inner surface of the aluminum alloy flat tube used. The outside of the flat tube has dense fins, 1.2m in length, 0.98m in width, and 6 bends. Forming. The Liebherr company in the Federal Republic of Germany uses special equipment for hot extrusion. We have undergone a lot of research. Based on local conditions, a modified design was made under the condition of ensuring the performance of the original machine, and passed the ministerial appraisal in October 1988.
