Description

Technical Field

[0001] This utility model relates to the field of spiral hose technology, and in particular to a spiral hose specifically designed for liquid cooling heat dissipation systems. Background Technology

[0002] The special spiral hose for liquid cooling heat dissipation system is a hose designed specifically for liquid cooling systems. Its tube body has a spiral bending structure. This spiral structure gives the hose good flexibility and spatial adaptability, allowing it to be flexibly bent and adjusted according to the equipment layout, while avoiding obstruction of coolant flow due to excessive bending or twisting.

[0003] Currently, existing spiral hoses for liquid cooling systems typically have basic liquid transfer functions and a certain degree of flexibility, but they cannot effectively compensate for the expansion and contraction caused by the thermal expansion and contraction of the pipes due to changes in coolant temperature. This leads to stress concentration in the pipes, which can then cause deformation or rupture, affecting the stability and safety of the system operation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot effectively compensate for the expansion and contraction of pipes caused by changes in coolant temperature, leading to stress concentration in the pipes and subsequent deformation or rupture. Therefore, this invention proposes a special spiral hose for liquid cooling heat dissipation systems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A special spiral flexible hose for liquid cooling heat dissipation systems, comprising: The spiral flexible hose body includes a contact layer, a reinforcing layer, and a protective layer. A corrugated pipe is fixedly connected to the middle section of the spiral flexible hose body. A female connector and a male connector are respectively connected to the inlet and outlet ends of the spiral flexible hose body.

[0006] In one possible design, the contact layer is the inner layer of the spiral flexible tube, and the material of the contact layer is polytetrafluoroethylene.

[0007] In one possible design, the reinforcing layer is the middle layer of the spiral flexible tube, and the material of the reinforcing layer is stainless steel wire.

[0008] In one possible design, the protective layer is the outer layer of the spiral flexible tube body, and the material of the protective layer is polyvinyl chloride.

[0009] In one possible design, both the female and male connectors have a fixed metal barb tube at their bottom. Both the female and male connectors are connected to the inlet and outlet ends of the spiral hose body through the metal barb tube. A receiving groove is provided below the outer ring of the female connector, and a sealing ring can be detachably installed in the receiving groove.

[0010] In one possible design, the inner wall of the male connector has a placement groove, and a sealing gasket is embedded in the placement groove.

[0011] In this application, upon initial use, the female and male connectors with the installed metal barbed tubes are connected to the inlet and outlet ends of the spiral hose body, respectively, allowing the metal barbed tube to insert into the spiral hose body and achieve communication. This connection method ensures smooth liquid flow within the tube. Subsequently, the spiral hose body is connected to the liquid cooling system via the female and male connectors. During installation, ensure the sealing ring is fully embedded in the receiving groove without twisting or protrusion to guarantee a good seal. For the male connector, the sealing gasket is embedded into the placement groove on the inner wall of the male connector, ensuring the gasket is installed flat and tightly fitted to the placement groove to prevent leaks during subsequent use. After installation, a simple water flow test can be performed to observe for any leaks. If leaks are found... Problems need to be identified and the sealing components reinstalled or adjusted promptly to ensure that the hose is installed correctly and can be put into normal use. During the operation of the liquid cooling system, the coolant circulates within the spiral hose. The sealing ring and gasket effectively prevent coolant from leaking out from the connection points. This not only avoids coolant waste and reduces operating costs, but also prevents damage to surrounding equipment caused by coolant leakage, ensuring the stable operation of the entire cooling system. At the same time, when the liquid cooling system is working, the hose may be subjected to the pressure of the internal coolant and the mechanical forces of the external environment. The metal barbed tube can prevent the pipe from loosening, falling off, or deforming due to these forces, ensuring the stability and reliability of the hose connection, so that the coolant can flow continuously and stably within the tube, ensuring the heat dissipation effect. The inner contact layer of the spiral hose is made of PTFE, which is corrosion-resistant, high-temperature resistant, and chemically stable. It can directly contact the coolant, preventing coolant leakage and ensuring no pollution during long-term use. It is adaptable to coolants of different compositions and temperatures. The middle reinforcing layer of stainless steel wire provides the pipe with strength and tensile strength, preventing deformation or rupture caused by internal pressure or external mechanical forces. The outer protective layer of PVC protects the pipe from damage caused by external environments such as ultraviolet rays, chemicals, and mechanical abrasion, extending the service life of the hose and providing wear resistance and weather resistance. It also has flame retardant or antistatic properties, improving the safety and reliability of the pipe, enabling the spiral hose to work stably in various complex industrial or electronic equipment heat dissipation environments. Meanwhile, when the liquid cooling system is working, the corrugated pipe in the middle section of the spiral flexible tube can compensate for thermal expansion and contraction, absorb the expansion and contraction of the pipe caused by temperature changes, and avoid stress concentration. During the operation of the liquid cooling system, the temperature of the coolant will change, causing the pipe to expand and contract. Without the compensation of the corrugated pipe, the pipe will deform or break due to stress concentration, affecting the normal operation of the system. The setting and use of the corrugated pipe can effectively solve this problem and ensure the stability and safety of the pipe when the temperature changes.

[0012] This utility model has the following beneficial effects: In this invention, the use of corrugated pipes allows for effective compensation of the expansion and contraction of pipes caused by temperature changes in the coolant during the operation of the liquid cooling system. This is achieved by leveraging the corrugated pipes' flexibility and extensibility, thus preventing stress concentration, deformation or rupture of the pipes due to temperature changes, ensuring the stability and safety of the pipes during temperature fluctuations, and guaranteeing the normal operation of the system.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] In one embodiment Reference Figure 1-5 A flexible hose, comprising: The spiral hose body 1, corrugated pipe 2, female connector 3, and male connector 4, etc., work together to achieve safe and stable delivery of coolant in the liquid cooling system. The spiral hose body 1 is the core part of the entire spiral hose. It adopts a three-layer composite structure, namely the contact layer 101, the reinforcing layer 102, and the protective layer 103.

[0017] The contact layer 101 serves as the inner layer of the spiral hose body 1. The contact layer 101 is in direct contact with the coolant. In order to meet the requirements of use in liquid cooling heat dissipation systems, the contact layer 101 is made of polytetrafluoroethylene (PTFE). PTFE has excellent properties such as corrosion resistance, high temperature resistance, and strong chemical stability, which can effectively prevent coolant leakage and ensure that it will not cause contamination to the coolant during long-term use. It is adaptable to coolants with different compositions and temperatures (for example, in some high-temperature industrial liquid cooling heat dissipation scenarios with complex coolant compositions, the contact layer 101 can still maintain good performance and ensure the normal circulation of the coolant).

[0018] The reinforcing layer 102 is located in the middle layer of the spiral hose body 1. The reinforcing layer 102 is made of stainless steel wire. Stainless steel wire has high strength and good tensile properties, which can provide reliable support for the pipeline. During the operation of the liquid cooling heat dissipation system, the pipeline will be subjected to the pressure of the coolant inside and may also be subjected to mechanical forces outside. The reinforcing layer 102 can effectively prevent the pipeline from deforming or breaking due to internal pressure or external mechanical forces, and ensure the structural integrity of the pipeline (for example, when the spiral hose 1 is subjected to a large external force or the internal coolant pressure suddenly increases, the reinforcing layer 102 can disperse the stress and avoid damage to the pipeline).

[0019] The protective layer 103 serves as the outer layer of the spiral hose body 1. The protective layer 103 is made of polyvinyl chloride (PVC). PVC has good wear resistance and weather resistance, which can protect the pipeline from damage caused by external environments such as ultraviolet rays, chemicals, and mechanical wear. At the same time, PVC also has flame retardant or antistatic properties, which further improves the safety and reliability of the pipeline (for example, in some outdoor environments or liquid cooling environments with flammable and explosive gases, the flame retardant and antistatic properties of the protective layer 103 can effectively reduce safety hazards and extend the service life of the hose).

[0020] A corrugated pipe 2 is fixedly connected to the middle section of the spiral flexible hose body 1. The inner and outer layers of the corrugated pipe 2 are made of the same material as the spiral flexible hose body 1. When the liquid cooling heat dissipation system is running, the temperature of the coolant will change, which will cause the pipe to expand and contract due to thermal expansion. Without effective compensation measures, the pipe will deform or break due to stress concentration, affecting the normal operation of the system. The corrugated pipe 2, with its own flexibility and extensibility, can effectively compensate for the expansion and contraction of the pipe caused by thermal expansion and contraction, and avoid stress concentration (for example, when the coolant temperature rises and the pipe expands, the corrugated pipe 2 can extend accordingly; when the coolant temperature drops and the pipe contracts, the corrugated pipe 2 can shorten accordingly, thereby ensuring the stability and safety of the pipe when the temperature fluctuates).

[0021] This application can be used in the field of spiral flexible hose technology for liquid cooling heat dissipation systems, and can also be used in other fields applicable to this application.

[0022] In another embodiment Reference Figure 3-4 A special spiral hose for liquid cooling systems is disclosed. This invention relates to the field of special spiral hoses for liquid cooling systems. The spiral hose body 1 has a female connector 3 and a male connector 4 connected to its inlet and outlet ends, respectively. Both the female connector 3 and the male connector 4 have a fixed metal barb tube 5 at their bottom, which connects to the inlet and outlet ends of the spiral hose body 1. The metal barb tube 5 increases the stability and reliability of the connection to the inlet and outlet ends of the spiral hose body 1. During operation of the liquid cooling system, the hose is subjected to the pressure of the internal coolant and the mechanical forces of the external environment. The metal barb tube 5 prevents the hose from loosening, falling off, or deforming due to these forces, ensuring that the coolant can flow continuously and stably within the hose.

[0023] A receiving groove is provided below the outer ring of the connecting female 3. A sealing ring 301 is detachably installed in the receiving groove. During installation, it is necessary to ensure that the sealing ring 301 is fully embedded in the receiving groove without twisting or protruding, so as to ensure a good sealing effect. The sealing ring 301 can effectively prevent coolant from leaking out from the connecting female 3, avoiding coolant waste and damage to surrounding equipment (for example, when connecting the hose to the liquid cooling system, carefully check the installation of the sealing ring 301 to ensure its good sealing performance).

[0024] The inner wall of the male connector 4 has a placement groove, and a sealing gasket 401 is embedded in the placement groove. Similarly, it is necessary to ensure that the sealing gasket 401 is installed flat and fits tightly with the placement groove to prevent poor sealing during subsequent use. The sealing gasket 401 and the sealing ring 301 work together to further enhance the sealing of the connection and ensure the stable operation of the liquid cooling heat dissipation system (for example, after completing the connection between the male connector 4 and the spiral hose body 1, a simple water flow test is performed to observe whether there is any leakage. If leakage is found, the installation of the sealing gasket 401 should be checked and adjusted in time).

[0025] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
