[0018] In order to make the person skilled in the art better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0019] The heat dissipation performance, noise and volume of the liquid cooling system are the main factors affecting the competitiveness of the liquid cooling product. Among them, the pipeline used in the current liquid cooling will form air bubbles in the water pipe when filling the cooling liquid, that is, the liquid filling rate of the pipeline cannot reach 100%. The liquid filling rate of the water pipe is an important factor restricting the reduction of volume and the reduction of noise. However, the conventional water pipe currently used is difficult to form a high liquid filling rate, resulting in poor heat dissipation performance, more noise and larger volume of the liquid cooling system assembled with such water pipe, which seriously affects the user experience of related products and reduces the attractiveness of the products.

[0020] To solve the problem of low liquid filling rate in the liquid cooling pipeline, the existing technical solutions mainly include: 1. Increasing the pressure of the liquid in the pipeline through a piston assembly to improve the liquid filling rate in the water pipe; 2. Using a liquid filling device with better performance to avoid the generation of bubbles in the water pipe. The above two solutions can improve the liquid filling rate in the water pipe, but the first solution will increase the number of components, which will increase the cost of project development and the reliability of the overall system control; the second solution will significantly increase the project cost.

[0021] Therefore, the inventors of the present application provide a liquid cooling pipeline and a liquid cooling device to at least partially solve the above technical problems, which will be described in detail below in combination with specific embodiments.

[0022] Referring to Figure 1 The liquid cooling pipeline 20 includes a deformable inner tube 40 and an outer tube 30. The inner tube 40 is arranged inside the outer tube 30 and can be deformed under the action of an external force. The inner tube 40 forms a filling space 43 for filling cooling liquid. The cooling liquid can be water, alcohol, or any other suitable liquid medium for cooling and heat conduction, which is not limited in the present embodiment.

[0023] The longitudinal section of the inner tube 40 can be circular, rectangular, or any other shape, which is not limited in the present embodiment. When the outer surface of the inner tube 40 is subjected to inward pressure, the inner tube 40 can be deformed towards the center, thereby extruding the cooling liquid inside the inner tube 40.

[0024] The inner tube 40 can be made of a flexible material with elasticity, forming a flexible structure. This material can deform under pressure and recover after the pressure disappears, avoiding irreversible deformation of the inner tube 40 after being extruded by an external force. In one embodiment, the inner tube 40 can be a rubber tube. Rubber material has high elasticity, low modulus, and excellent recovery performance, which enables the rubber tube to deform under the action of an external force and quickly recover to its original state after the external force disappears. Of course, it can be understood that in other embodiments, the inner tube 40 can also be made of other flexible materials, such as flexible and elastic materials like silicone.

[0025] The outer tube 30 is arranged outside the inner tube 40, and the longitudinal section of the outer tube 30 can be circular, rectangular or any other shape. In the embodiment, the longitudinal sections of the inner tube 40 and the outer tube 30 are both substantially circular, and the inner tube 40 and the outer tube 30 are arranged substantially coaxially, with the outer tube 30 surrounding the outer side of the inner tube 40. The inner surface of the outer tube 30 and the outer surface of the inner tube 40 form a gas-filled space 33, which is used to fill high-pressure gas. The high-pressure gas can be nitrogen, air or the like, which are safe and low in cost. Of course, the high-pressure gas can also be other gases, which are not limited in the embodiment.

[0026] In the process of filling the high-pressure gas into the gas-filled space 33, the inner tube 40 is subjected to pressure, and the inner surface of the outer tube 30 is also subjected to pressure from the high-pressure gas, so as to prevent the outer tube 30 from deforming. The outer tube 30 can adopt a hard structure, i.e., the outer tube 30 is made of hard material. In some embodiments, the outer tube 30 can be a metal tube made of metal material, such as a stainless steel tube, a copper tube or the like, which are not limited in the embodiment.

[0027] Specifically, in the embodiment, the two ends of the inner tube 40 are respectively provided with a first water inlet 41 and a first water outlet 42, the two ends of the outer tube 30 are provided with a second water outlet 32 and a second water inlet 31, the first water outlet 42 and the second water outlet 32 are communicated, the first water inlet 41 and the second water inlet 31 are communicated, and the two ends of the outer tube 30 and the two ends of the inner tube 40 are respectively connected to seal the gas-filled space 33. In other embodiments, the outer tube 30 and the inner tube 40 can also be sealed by welding, arranging other sealing members or the like, which are not limited in the embodiment.

[0028] The high-pressure gas filled in the gas-filled space 33 can be filled when the inner tube 40 and the outer tube 30 are prepared, or can be filled when the cooling liquid is filled, i.e., filled when the application environment is assembled. In order to facilitate the on-site filling of high-pressure gas by the operator, in the embodiment, the outer tube 30 is provided with an air inlet hole 34, the air inlet hole 34 is communicated with the gas-filled space 33, and the air inlet hole 34 is provided with a valve 50. The valve 50 can be a manual valve which can be manually controlled to open and close, or can be an automatic valve which can be automatically controlled to open and close, such as an electromagnetic valve, which are not limited in the embodiment.

[0029] The air inlet hole 34 can be opened along the radial direction of the outer tube 30 and pass through the outer tube 30, and it can be understood that the air inlet hole 34 can be one or more, which is not limited in the embodiment. In use, the valve 50 is opened, and the air inlet hole 34 is filled with air by an external air filling device (such as an air pump), and when the air pressure in the air filling space 33 increases, the inner tube 40 is pressed to deform.

[0030] The working principle of the liquid cooling pipeline 20 provided by the embodiment is as follows:

[0031] In the process of filling the cooling liquid into the inner tube 40, a plurality of air bubbles are formed in the inner tube 40, at this time, the valve 50 is opened, and the air filling space 33 is filled with high-pressure gas, such as air, by the air filling device through the air inlet hole 34. The high-pressure gas forms pressure on the inner tube 40, and the inner tube 40 is pressed to the center, the air bubbles in the inner tube 40 are pressed to move to the first air inlet or the first air outlet at both ends of the inner tube 40, and finally escape from the first air inlet or the first air outlet. After the air bubbles escape, the cooling liquid can continue to be injected into the inner tube 40 to fill the volume of the discharged air bubbles, so that the liquid filling rate in the inner tube 40 can be increased, the heat dissipation effect can be improved, and the noise generated by the flow of the cooling liquid can be reduced.

[0032] After the cooling liquid is filled, the high-pressure gas can be filled in the air filling space 33, or the high-pressure gas in the air filling space 33 can be discharged by opening the valve 50.

[0033] The liquid cooling pipeline 20 provided by the embodiment fills the high-pressure gas into the air filling space 33 when filling the cooling liquid, and the inner tube 40 is deformable, which is pressed and deformed inward under the pressure of the high-pressure gas, so that the air bubbles in the inner tube 40 can be extruded outward, thereby increasing the liquid filling rate in the inner tube 40, improving the liquid cooling heat dissipation effect, and reducing the noise and improving the heat dissipation efficiency during the flow and heat dissipation of the cooling liquid.

[0034] In addition, the embodiment also provides a liquid cooling device (not shown), which comprises the liquid cooling pipeline 20 described above, the inner tube 40 in the liquid cooling pipeline 20 is filled with cooling liquid, the cooling liquid flows and exchanges heat with a heat source, and then flows to a cold source to exchange heat, and the cooling liquid can circulate to achieve heat dissipation. Of course, the liquid cooling device can also use other liquid cooling methods, which are not limited in the embodiment.

[0035] The above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
