The pipeline classification can be divided into straight pipes and reducing pipes from the change of the cross section of the pipeline, and the pipeline shape can be divided into corrugated pipes, square pipes, flat pipes and composite pipelines thereof.

In the existing high-power-density liquid cooling scene, a pipeline is required to transport cooling liquid to cool heating equipment, pipeline classification can be divided into a straight pipe and a reducing pipe from the change of the cross section of the pipe, and pipeline shape can be divided into corrugated pipes, square pipes, flat pipes and composite shape pipelines thereof. In order to reduce the intermediate connecting piece, a pipe is generally adopted for connection, for example, a single smooth round pipe or corrugated pipe is adopted, the smooth round pipe is simple to process and high in reliability, but in the use process, the shape of a pipeline is required to be measured and bent according to the component layout in a specific scene, so that the pipeline is matched with the layout, and then the mounting bracket is stable and complex; the corrugated pipe omits the bending process, but the number of layers and the shape of the corrugated pipe are required to be determined according to the use, working pressure and other factors, so that the corrugated pipe needs to be customized, the cost is increased, and the pipeline can be bent at will, so that the shape of the pipeline is not attractive in the use process, and the pipeline can shake back and forth when being stressed or vibrated.

Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a composite pipe provided in an embodiment of the present application, and fig. 2 is a schematic structural diagram of a cross section of the composite pipe provided in an embodiment of the present application. The application provides a composite pipe 1, this composite pipe 1 includes a plurality of straight pipe sections 11 and a plurality of ripple pipe section 12, and a plurality of ripple pipe section 12 and a plurality of straight pipe section 11 staggered connection form composite pipe 1, and wherein, each ripple pipe section 12 and each straight pipe section 11 adopt single-layer material (individual layer structure, a material) integrated into one piece.

This application is through with a plurality of straight tube sections 11 and a plurality of bellows section 12 staggered connection, forms compound pipe 1, and establishes integrated into one piece to simplified the installation degree of difficulty, improved the reliability, prevented that each bellows section 12 and each straight tube section 11 from taking place weeping, oozing the phenomenon of liquid in the junction, guaranteed the leakproofness of pipeline. Meanwhile, the length requirements of different application scenes on the pipeline are different, the pipeline can be cut according to actual conditions, and the universality of the composite pipe 1 is improved.

In this embodiment, the corrugated tube section 12 may be applied to a scene requiring bending or limiting, the straight tube section 11 may be used to maintain the shape of the pipeline and support the pipeline to prevent the pipeline from being deformed due to stress, and the composite tube 1 is formed by alternately connecting the corrugated tube section 12 and the straight tube section 11, so that the stability of the pipeline is higher, the shaking problem of the corrugated tube section 12 can be reduced, and the composite tube is more attractive. Therefore, the composite pipe 1 in the present embodiment is able to cope with bending and deformation in a scene where the spatial structure is complex.

In some embodiments, the length of the straight tube section 11 and the length of the bellows section 12 are equal, and the length of each straight tube section 11 and the length of each bellows section 12 may be 10mm to 100mm; specifically, the length of the straight tube segment 11 and the length of the corrugated tube segment 12 may be 10mm, 40mm, 80mm, 100mm, etc., and may be specifically determined according to practical requirements.

In some embodiments, the length of the bellows segment 12 may also be greater than the length of the straight tube segment 11.

Referring to fig. 3, fig. 3 is a schematic side view of a composite tube according to an embodiment of the present disclosure. The sections of the straight pipe section 11 and the corrugated pipe section 12 are both set to be circular, and the inner diameter of the corrugated pipe section 12 is equal to the inner diameter of the straight pipe section 11, and the wall thickness of the straight pipe section 11 is equal to the wall thickness of the corrugated pipe section 12.

The flow resistance coefficient of the circular pipeline is the smallest among all the pipelines, so that the pipeline is favorable for conveying cooling liquid, the blockage cannot be caused, the stress of the circular pipeline is uniform, the stress distribution is balanced, and the pipeline cannot be damaged due to overlarge pressure at a certain position of the pipeline caused by uneven stress. In this embodiment, the sections of the straight pipe section 11 and the corrugated pipe section 12 are both circular, so that the composite pipe 1 can be ensured to smoothly transport the cooling liquid, and meanwhile, the phenomenon of pipeline rupture caused by overlarge pressure is avoided. Meanwhile, if the inner diameter of the composite pipe 1 is changed from small to large, insufficient pressure is caused, and the cooling liquid cannot be transported smoothly; if the inner diameter of the composite pipe 1 is reduced from large to small, the flow resistance is increased, and the pressure is increased, and the pipe line may be broken due to excessive pressure. The present embodiment further ensures that the composite pipe 1 can smoothly transport the coolant by setting the inner diameter of the bellows section 12 to be equal to the inner diameter of the straight pipe section 11, while avoiding the phenomenon of pipe breakage caused by excessive pressure. In addition, in the present embodiment, the wall thickness of the straight pipe section 11 is set to be equal to the wall thickness of the corrugated pipe section 12, so that the pipe is prevented from being cracked at a place where the pipe wall is relatively thin due to uneven pressure bearing caused by uneven wall thickness.

In this embodiment, the straight pipe section 11 and the corrugated pipe section 12 are made of any one of copper, or copper alloy, or FEP (Fluorinated ethylene propylene-perfluoroethylene propylene copolymer), or PVC (Polyvinyl chloride-polyvinylchloride), or PTFE (Polytetrafluoroethylene-Polytetrafluoroethylene), and are made by a single-layer integral molding process, and the copper, copper alloy, FEP, PVC and PTFE have high stability, can withstand high and low temperatures, and are not affected in different environments, so that the composite pipe 1 is prevented from cracking and deforming due to low temperature of the cooling liquid in the process of conveying the cooling liquid. Copper is corrosion-resistant, the service life is long, and the cost is reduced; wherein, the selection of the single material can be selected according to the type of the cooling liquid conveyed in the scene application; the single-layer structure is simple, the defects are few, the reliability is higher, and the pipe body with the single-layer structure is softer under the same condition.

Referring to fig. 4 and 5, fig. 4 is a schematic structural view of a composite pipe according to an embodiment of the present application after installation, and fig. 5 is a schematic structural view of a composite pipe according to another view angle according to an embodiment of the present application after installation. Both ends of the composite pipe 1 are provided with straight pipe sections 11 so as to facilitate the connection of the composite pipe 1 with other structures.

In other embodiments, the length of the composite pipe 1 can be designed to different length specifications according to the actual installation requirements. For example, the ratio of the length of each straight pipe section 11 to the length of each corrugated pipe section 12 depends on the requirement of the space of the application scene on the bending radius, if the requirement on the bending radius is larger, the length of each corrugated pipe section 12 can be set to be larger than the length of each straight pipe section 11, so that bending is convenient; if the bending radius is required to be small, the length of each bellows segment 12 may be set to be smaller than or equal to the length of each straight segment 11.

The application also provides a cooling device, which comprises a compressor, a condenser, an expansion valve, an evaporator and the composite pipe 1 in any embodiment, wherein the compressor, the condenser, the expansion valve and the evaporator are sequentially connected through the composite pipe 1.

The foregoing is merely a preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the technical scope of the present application should be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
