The embodiment of the invention provides a manufacturing method of a refrigerant pipeline system 100.
In an embodiment of the present invention, as shown in fig. 1 to 3, the method for manufacturing the refrigerant pipeline system 100 includes the following steps:
s1, fixing a refrigerant pipeline 110 in a foaming mold;
s2, preparing a foaming raw material, and pouring the foaming raw material into a foaming mold;
s3, heating the foaming raw material to obtain a foaming material layer 120, wherein the foaming material layer 120 is wrapped and adhered to the periphery of the refrigerant pipeline 110;
and S4, cooling and demolding to obtain the refrigerant pipeline system 100.
Specifically, the foaming mold comprises a fixed mold and a movable mold, a foaming cavity is formed between the fixed mold and the movable mold, the refrigerant pipeline 110 is fixed in the foaming mold, and at least part of the refrigerant pipeline 110 extends into the foaming cavity. The foaming material is then poured into the foaming chamber such that the refrigerant line 110 is at least partially immersed in the foaming material. Subsequently, by heating the foaming material, the foaming material reacts and expands until it fills the entire foaming chamber. Finally, the foam material layer 120 is cooled and demolded, and the periphery of the refrigerant pipeline 110 is tightly wrapped by the obtained foam material layer 120, and a gap is basically not formed between the foam material layer 120 and the refrigerant pipeline 110, so that the foam material layer 120 and the refrigerant pipeline 110 are adhered together. The refrigerant pipeline 110 includes a plurality of pipeline components and welding portions, and any two pipeline components are connected by the welding portions. In the technical solution of this embodiment, when the refrigerant pipeline 110 is fixed in the foaming mold, the welding portion is exposed outside the foaming cavity, so that the obtained foaming material layer 120 can avoid the welding portion, and the refrigerant in the pipeline is prevented from leaking due to the corrosion of the solder by the foaming material. In addition, the technical scheme of the embodiment adopts a polyurethane foaming raw material to obtain a polyurethane foaming material layer. Of course, in other embodiments, polystyrene, polyethylene, or phenolic foam may also be used. It can be understood that the foaming material has certain flexibility and elasticity, and can convert the energy of the vibration of the refrigerant pipeline 110 into the elastic potential energy of the foaming material. In addition, the foaming material also has a large number of micropore structures which are communicated with the outside, so that sound waves can easily enter the micropores and are absorbed by the material, and the foaming material also has good sound absorption performance.
It is understood that the air conditioning compressor includes a compressor body, a piping system, and a liquid storage tank. The compressor body can generate large vibration in the working process to cause vibration of a pipeline system connected with the compressor body. In addition, the refrigerant entering the liquid storage tank from the pipeline system is low-temperature high-pressure liquid, and can impact the inner wall surface of the liquid storage tank, so that the liquid storage tank can vibrate, and the pipeline system connected with the liquid storage tank can vibrate. If the pipe system vibrates too much, on the one hand, noise is generated and, on the other hand, the risk of breakage of the pipe is increased. In the related art, the pipeline system is usually provided with the anti-vibration rubber and the balancing weight for vibration reduction, but the vibration reduction effect is limited, the vibration quantity of the pipeline system is still large, and in the assembling process, the probability of pipeline deformation is increased due to the existence of assembling errors.
The invention provides a method for manufacturing a refrigerant pipeline system 100, which comprises the steps of fixing a refrigerant pipeline 110 in a foaming mold, preparing a foaming raw material, pouring the foaming raw material into the foaming mold, heating the foaming raw material to expand the foaming raw material, wrapping and adhering an obtained foaming material layer 120 on the periphery of the refrigerant pipeline 110, and finally cooling and demolding to obtain the refrigerant pipeline system 100. According to the technical scheme, the foaming material layer 120 is tightly wrapped on the refrigerant pipeline 110 and is bonded with the refrigerant pipeline 110, so that the vibration quantity of the refrigerant pipeline 110 can be obviously reduced, the risk of pipeline fracture is reduced, and the noise generated by pipeline vibration is reduced; in addition, the refrigerant pipeline system 100 with the outer layer wrapped by the foam material layer 120 can be directly obtained by the manufacturing method, and a vibration damping part does not need to be additionally assembled on the refrigerant pipeline system 100, so that the pipeline deformation caused by the non-standard assembly is avoided, and the vibration and radiated noise caused by the pipeline deformation is reduced.
Further, the step S1 includes the following steps:
s11, mixing the polyhydric alcohol and the chain extender to obtain a first mixture
S12, mixing the polyurethane prepolymer with a flame retardant to obtain a second mixture;
and S13, mixing the first mixture and the second mixture to obtain a foaming raw material.
Further, the foam layer 120 is a polyurethane foam layer. Compared with other foaming materials, the polyurethane foaming material has better stability, chemical resistance, rebound resilience and mechanical property. According to the technical scheme, the mechanical property of the polyurethane foam material is further improved by regulating and controlling the foaming raw materials and the ratio thereof again, so that the polyurethane foam material layer has a more obvious damping effect, and the vibration quantity of the refrigerant pipeline system 100 can be obviously reduced.
In the embodiment, the chain extender is added into the polyurethane foaming raw material, so that the molecular chain diffusion of the polyurethane prepolymer can be prolonged, the molecular weight is remarkably increased, and on one hand, the mechanical property of the polyurethane foaming material can be improved, so that the obtained polyurethane foaming material layer has better flexibility and elasticity, and the vibration damping effect is enhanced; on the other hand, the temperature resistance of the polyurethane foam material can be improved, and the temperature resistance range of the polyurethane foam material is expanded. Specifically, the temperature resistance range of the polyurethane foam material layer in this embodiment may reach-30 to 110 ℃, and it can be understood that the refrigerant in the refrigerant pipeline system 100 may be continuously switched between a high temperature and a low temperature, so that the technical scheme of this embodiment can improve the chemical stability of the foam material and the adaptability to different temperature conditions by improving the temperature resistance of the foam material. Specifically, the chain extender comprises at least one of trimethylolpropane, 3, 5-dimethylthiotoluenediamine, butanediol and the like.
In the step S13, the ratio of the first mixture to the second mixture is 1: 2-1: 3. It can be understood that if the ratio of the two is too large, the addition amount of the chain extender is too large, which results in the foamed material layer 120 being hard, brittle and poor in resilience, so that the foamed material layer 120 is easy to lock and fasten the refrigerant pipeline 110, and is not beneficial to damping the pipeline system; if the proportion of the chain extender and the foaming material layer is too small, the addition amount of the chain extender is too small, so that the foaming material layer 120 is soft, the mechanical property is poor, and the vibration reduction effect is poor. According to the technical scheme of the embodiment, the ratio of the first mixture to the second mixture is reasonably controlled to ensure that the prepared foaming material layer 120 has good mechanical property, so that the vibration reduction effect of the foaming material layer on a pipeline system is improved.
In the step S3, the heating temperature of the foaming raw material is 60-90 ℃. Of course, in other embodiments, other temperature ranges may also be adopted to process the foaming raw material, but based on the above embodiments, the embodiment can reduce the foaming time of the polyurethane foaming raw material by reasonably controlling the heating temperature of the polyurethane foaming raw material, so as to improve the foaming efficiency, and meanwhile, avoid the heating temperature exceeding the temperature-resistant range of the polyurethane foaming material, so as to avoid affecting the performance of the polyurethane foaming material.
In the step S11, the polyol is prepared by mixing and reacting carboxylic acid, polyethylene glycol diacid ester and diphenylmethane diisocyanate at the temperature of 20-60 ℃.
In the step S12, the polyurethane prepolymer is prepared by mixing and reacting alcohol ester and isocyanate. The alcohol ester can effectively reduce the odor of the polyurethane prepolymer, so that the odor of the prepared foaming material layer 120 and the refrigerant pipeline system 100 is reduced. Specifically, the alcohol ester comprises at least one of neopentyl glycol adipate and neopentyl glycol succinate; the isocyanate includes at least one of toluene diisocyanate and diphenylmethane isocyanate.
In addition, when a high-temperature and high-pressure refrigerant flows through the refrigerant pipeline system 100, a large amount of heat energy is dissipated, so that the polyurethane foam material layer prepared by the embodiment has good flame retardant performance by adding the flame retardant into the foaming raw material, thereby avoiding safety accidents caused by the large amount of heat energy dissipated by the refrigerant.
The embodiment of the invention further provides a refrigerant pipeline system 100, which is manufactured by the manufacturing method of the refrigerant pipeline system 100.
As shown in fig. 2 and 3, the refrigerant pipeline system 100 includes a refrigerant pipeline 110 and a foam layer 120, the foam layer 120 is wrapped around the refrigerant pipeline 110, and the foam layer 120 and the refrigerant pipeline 110 are bonded together. In the technical scheme of this embodiment, the refrigerant pipeline 110 is tightly wrapped by the foam material layer 120 and is tightly bonded to the foam material layer 120, so that on one hand, the vibration quantity generated by the refrigerant pipeline 110 is directly transmitted to the foam material layer 120, and the foam material layer 120 converts the vibration energy of the refrigerant pipeline 110 into the elastic potential energy of the foam material to the greatest extent, thereby significantly reducing the vibration quantity of the whole pipeline system; on the other hand, the refrigerant pipeline 110 can be effectively prevented from deforming and the refrigerant pipeline 110 can be prevented from being broken.
Further, the foam layer 120 is a polyurethane foam layer. Compared with other foaming materials, the polyurethane foaming material has better stability, chemical resistance, rebound resilience and mechanical property. According to the technical scheme, the mechanical property of the polyurethane foam material is further improved by regulating and controlling the foaming raw materials and the ratio thereof again, so that the polyurethane foam material layer has a more obvious damping effect, and the vibration quantity of the refrigerant pipeline system 100 can be obviously reduced. As shown in fig. 6, in the operation process of the compressor 200, compared to the refrigerant pipeline system 100 without the foamed material layer 120, the amplitude of the refrigerant pipeline system 100 provided in this embodiment is significantly reduced, and the amplitude is reduced by as much as 80% to 95%.
Further, as shown in fig. 2 to 4, the refrigerant pipeline 110 includes a plurality of pipeline components and welding portions, any two pipeline components are connected by the welding portions, and the foam material layer 120 wraps the peripheries of the pipeline components and exposes the welding portions. Specifically, the refrigerant pipeline 110 includes pipeline components such as an exhaust pipe 111, a muffler 112, a low-pressure valve 113, a four-way valve 114, and a valve cooling pipe 115, wherein one end of the exhaust pipe 111 is welded to an exhaust port of the compressor 200, and the other end is welded to the four-way valve 114; one end of the air return pipe 112 is welded with the liquid storage tank 300, and the other end is welded with the four-way valve 114; one end of the valve cooling pipe 115 is welded with the four-way valve 114, and the other end is welded with the heat exchanger 500; one end of the low pressure valve 113 is welded to the four-way valve 114. In this embodiment, the foaming material layer 120 wraps the exhaust pipe 111, the air return pipe 112, the valve cooling pipe 115 and the low-pressure valve 113 together, and avoids the welding portion, so as to prevent the refrigerant leakage of the pipeline system caused by the corrosion of the solder by the polyurethane foaming material.
As shown in fig. 3 and 4, the compressor assembly includes a compressor body 200, a liquid storage tank 300 and the refrigerant pipeline system 100, wherein the liquid storage tank 300 is communicated with the compressor body 200 through the refrigerant pipeline system 100.
