As shown in fig. 1, the water chiller is a schematic structural diagram of a civil water chiller in the prior art in a conventional pipeline fixing manner, and mainly comprises a shell pipe 100, a pipeline 200, a pipeline fixing bracket 300, a fixing pipe clamp 400 and other components; the shell and tube 100 may be an evaporator, a condenser, etc.; the pipeline 200 is used for conveying media such as a refrigerant or oil, most of the media have heat preservation or insulation requirements, and the pipeline 200 is often wrapped by a layer of heat preservation cotton 500. The pipe fixing bracket 300 is mainly used for fixing the suspended pipe 200, and preventing the pipe 200 from shaking, vibrating and the like. The fixing pipe clamp 400 is mainly used for fixing the pipeline 200 and tightly fixing the pipeline 200 on the fixing bracket 300. This kind of conventional pipeline fixed mode is unsettled pipeline more, and all be through the pipe clamp, the local support pipeline of mode of support, structural strength is little, the rigidity is low, when the abominable operating mode of unit operation, perhaps when little earthquake frequently takes place, cause pipeline vibration and pipeline shake easily, can damage the pipeline over time, cause oil piping system's leakage and fluorine way system's leakage etc., reduce the reliability of unit, stability and security, lead to this kind of structure can not satisfy special use scenes such as nuclear power plant, military plant, telecommunication data computer lab to equipment anti-seismic performance's needs far away.

As shown in fig. 2, in addition, because the evaporator shell tube (or the condenser shell tube in the case of heat pump) needs to be insulated, the insulation cotton 500 needs to be wrapped, because of the protruding fixing bracket 300, the insulation cotton 500 is not very convenient to wrap, and the working efficiency is low. The protruding fixing bracket 300 is thermally conductive because it is metallic. If the heat-insulating cotton is not wrapped on the fixed support, part of cold energy of the evaporator can be diffused to the external environment along with the metal support, so that the loss of the cold energy is caused, and if the heat-insulating cotton is wrapped on the support, the efficiency is extremely low.

As shown in fig. 9, further, the minimum inner diameter d of the pipeline body 1 is 10mm or more and 60mm or less.

Furthermore, the relation between the wall thickness T1 of the pipeline body 1 and the overall height D of the appearance of the pipeline body 1 is that T1 is more than or equal to 0.5mm and less than or equal to 1/10 multiplied by D. The overall height D of the pipeline body 1 is D + R1+ R2+ T1+ T2, wherein T1 is T2.
