Abstract
Description
Technical Field
[0001] This application relates to the field of thermal insulation pipe assembly technology, and more particularly to thermal insulation pipe assemblies that can prevent water vapor condensation. Background Technology
[0002] Energy storage devices generate a large amount of heat during operation. If this heat is not dissipated in time, the device may be damaged due to overheating. Therefore, liquid cooling pipelines are installed in energy storage devices. As the coolant circulates in the liquid cooling pipelines, it flows through the energy storage device and absorbs the heat generated by the device. Then, after passing through a cooler to cool the heat-absorbing coolant, it circulates back to the energy storage device to continuously absorb heat, forming a closed-loop system.
[0003] In existing technologies, when coolant flows through liquid-cooled piping, its temperature is lower than the ambient temperature outside the piping. As a result, the coolant absorbs heat from the piping, causing the surface temperature of the piping to drop below the ambient temperature. Since the air outside the piping contains moisture, this moisture loses heat upon contact with the piping surface and condenses into water droplets. These droplets falling into the energy storage device can cause a short circuit. Utility Model Content

[0030] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.
[0031] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.
[0032] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.
[0033] refer to Figures 1 to 13 A preferred embodiment of the heat-insulating pipe assembly that prevents water vapor condensation according to this application will be described in detail below, wherein the heat-insulating pipe assembly that prevents water vapor condensation includes an inner pipe body 10, at least one diversion component 20 and at least one outer pipe body 30.
[0034] Specifically, the inner tube 10 forms a medium channel 101 for the flow of coolant and at least one branch port 102 communicating with the medium channel 101. The branch port 102 is formed on the inner wall located in the extending direction of the medium channel 101.
[0035] The diversion component 20 is disposed on the inner tube body 10, and the diversion component 20 forms a diversion channel 201 communicating with the diversion port 102.
[0036] At least one of the outer tube bodies 30 is coaxially sleeved around the outer periphery of the inner tube body 10, and the extending direction of the outer tube body 30 is consistent with the extending direction of the inner tube body 10, forming at least one isolation cavity 301 between the inner tube body 10 and the at least one of the outer tube bodies 30. The outer tube body 30 also forms an adapter portion 302 adapted to the diversion component 20, so that the diversion component 20 is disposed on the inner tube body 10 in a manner that extends beyond the outer tube body 30.
[0037] It is understood that when coolant is circulated into the inner tube 10 and the inner tube 10 absorbs heat from the coolant, causing the outer surface of the inner tube 10 to cool down, the outer tube 30 is fitted over the outer periphery of the inner tube 10, and the isolation cavity 301 is formed between the inner tube 10 and the outer tube 30. The outer periphery of the inner tube 10 is blocked by the isolation cavity 301, and water vapor in the surrounding environment of the outer tube 30 cannot come into contact with the outer periphery of the inner tube 10. As a result, water vapor cannot condense on the outer surface of the inner tube 10 to form water droplets, thus avoiding short circuits in the internal circuitry of the energy storage device caused by water droplets forming on the outer surface of the inner tube 10.
[0038] If water droplets condense on the outer surface of the inner tube 10, the temperature of the inner tube 10 will rise. At this time, the coolant in the medium channel 101 of the inner tube 10 will further absorb the heat of the inner tube 10, resulting in energy loss of the coolant in the medium channel 101. In this solution, due to the obstruction of the isolation cavity 301, the energy loss of the coolant in the medium channel 101 caused by the condensation of water droplets on the surface of the inner tube 10 can be reduced, thereby improving the heat absorption efficiency of the coolant from the energy storage device.
[0039] Preferably, one end of the outer tube 30 is bent radially toward the inner tube 10 to form a first port bend 31, which is fused to the outer periphery of the end of the inner tube 10. The outer tube 30 is bent toward the inner tube 10 at the adapter portion 302 to form an adapter seal 32, which is fused to the surface of the inner tube 10. Alternatively, the first port bend 31 can also be formed by bending one end of the inner tube 10 radially toward the outer tube 30, and the adapter seal 32 can also be formed by bending the inner tube 10 at a location corresponding to the adapter portion 302 toward the outer tube 30.
[0040] Understandably, at this time, the isolation chamber 301 has only one port connected to the outside. Under the influence of the air pressure inside the isolation chamber 301, outside air cannot flow into the isolation chamber 301, thereby preventing water vapor in the outside air from entering the isolation chamber 301. This reduces the possibility of water droplets falling into the energy storage device due to the water vapor contained in the gas in the isolation chamber 301 contacting the surface of the inner tube 10, thus reducing the possibility of short circuits in the energy storage device.
[0041] like Figures 1 to 3 As shown, in this embodiment, the heat-insulating pipe assembly that prevents water vapor condensation further includes a first sealing member 40A. The first sealing member 40A is disposed at the end of the inner tube 10 away from the first port curved seal 31, so as to seal the isolation cavity 301 and the port of the medium channel 101 away from the first port curved seal 31 by means of the first sealing member 40A.
[0042] Preferably, the first sealing member 40A extends into the medium channel 101 in a manner that conforms to the inner wall of the medium channel 101 to form a first fixing member 41A. The first sealing member 40A extends along the surface of the outer tube 30 in a manner that conforms to the outer wall of the outer tube 30 to form a first wrapping member 42A.
[0043] As an example, the first sealing member 40A is disposed at the end of the inner tube 10 away from the first port curved seal 31. After the first sealing member 40A closes the isolation cavity 301 and the end of the medium channel 101 away from the first port curved seal 31, high temperature is applied to the first sealing member 40A to fuse the first sealing member 40A to the inner tube 10 and the outer tube 30. Under the combined action of the first port curved seal 31 and the adapter sealing part 32, the isolation cavity 301 is closed to prevent water vapor contained in the gas in the isolation cavity 301 from condensing into water droplets and falling into the energy storage device upon contact with the surface of the inner tube 10.
[0044] During the process of applying high temperature to the first sealing member 40A, due to the formation of the first fixing member 41A and the first wrapping member 42A, the first fixing member 41A and the first wrapping member 42A will be fused to the inner wall of the medium channel 101 and the outer wall of the outer tube 30 respectively, thereby improving the stability of the first sealing member 40A as a whole located at the end of the outer tube 30.
[0045] It should be noted that, due to the setting of the first sealing component 40A, after the coolant enters the medium channel 101, it will sequentially pass through at least one of the diversion ports 102 and enter at least one of the diversion channels 201, thereby achieving diversion.
[0046] Specifically, in this embodiment, the diversion component 20 is implemented as a saddle connector, the diversion component 20 is welded to the inner tube body 10 at high temperature, and the adapter portion 302 is a saddle-shaped hole adapted to the diversion component 20. The inner circumference of the saddle-shaped hole of the adapter portion 302 is bent toward the inner tube body 10 to form the adapter sealing portion 32. As a deformable embodiment, such as Figure 4 and Figure 5 As shown, the diversion component 20 includes a socket weld tee connector. The inner tube 10 and the outer tube 30 are both divided into two sections. Similarly, each of the two outer tube sections 30 has an adapter 302. The two inner tube sections 10 are respectively inserted into the diversion component 20 and welded to the diversion component 20 at high temperature. The adapter 302 is an annular tube that is adapted to the outer periphery of the connector of the diversion component 20 inserted by the inner tube 10 and is coaxial with the inner tube 10. The adapter 302 is bent toward the inner tube 10 to form the adapter sealing part 32.
[0047] like Figures 6 to 7As shown in the first modified embodiment of this application, the end of the inner tube 10 away from the first port bend seal 31 extends along the extension direction of the inner tube 10 to form a second receiving portion 11B. The heat-insulating tube assembly that prevents water vapor condensation further includes a second sealing member 40B. The second sealing member 40B includes a second port closure member 41B and a second wrapping member 42B. The second port closure member 41B is disposed at the second receiving portion 11B of the inner tube 10, and the second port closure member 41B closes the port of the medium channel 101 away from the first port bend seal 31. The second wrapping member 42B covers the second receiving portion 11B in the circumferential direction, and one end of the second wrapping member 42B along the extension direction of the inner tube 10 is fixedly connected to the second port closure member 41B. The other end of the second wrapping member 42B along the extension direction of the inner tube 10 is inserted into the port of the isolation cavity 301 away from the first port curved seal portion 31 in an interference fit manner.
[0048] As an example, by applying high temperature to the second sealing member 40B, the second port closure 41B of the second sealing member 40B is fused to the end of the second receiving part 11B, and the second wrapping member 42B is fused to the second receiving part 11B and the inner wall of the isolation cavity 301. This closes the port of the medium channel 101 away from the first port curved seal 31 through the second port closure 41B, and seals the isolation cavity 301 under the combined action of the first port curved seal 31, the adapter sealing part 32, and the second wrapping member 42B. This prevents water vapor contained in the gas in the isolation cavity 301 from condensing into water droplets and falling into the energy storage device upon contact with the surface of the inner tube 10.
[0049] Since the second wrapping member 42B is partially inserted into the isolation cavity 301, the stability of the second wrapping member 42B in sealing the isolation cavity 301 is improved when the second wrapping member 42B is fused to the inner wall of the isolation cavity 301.
[0050] It is worth mentioning that the second wrapping member 42B not only improves the stability of the second port closure member 41B when it is located at the second receiving part 11B, but also closes the port of the isolation cavity 301 away from the first port curved sealing part 31 through the second wrapping member 42B.
[0051] It should be noted that, due to the setting of the second port closure 41B of the second sealing member 40B, after the coolant enters the medium channel 101, it will sequentially pass through at least one of the diversion ports 102 and enter at least one of the diversion channels 201, thereby realizing diversion.
[0052] Specifically, in this modified embodiment, the diversion component 20 is implemented as including a saddle connector, the diversion component 20 is welded to the inner tube body 10 at high temperature, and the adapter portion 302 is a saddle-shaped hole adapted to the diversion component 20. The inner circumference of the saddle-shaped hole of the adapter portion 302 is bent toward the inner tube body 10 to form the adapter sealing portion 32. As a variant, such as Figure 8 and Figure 9 As shown, the diversion component 20 includes a socket weld tee connector. The inner tube 10 and the outer tube 30 are both divided into two sections. Similarly, each of the two outer tube sections 30 has an adapter 302. The two inner tube sections 10 are respectively inserted into the diversion component 20 and welded to the diversion component 20 at high temperature. The adapter 302 is an annular tube that is adapted to the outer periphery of the connector of the diversion component 20 inserted by the inner tube 10 and is coaxial with the inner tube 10. The adapter 302 is bent toward the inner tube 10 to form the adapter sealing part 32.
[0053] like Figures 10 to 11 As shown in the second modified embodiment of this application, one end of the outer tube 30 away from the first port bend 31 is bent radially toward the inner tube 10 to form a second port bend 33C, and the second port bend 33C is fused to the outer periphery of the inner tube 10, so that the isolation cavity 301 is sealed under the combined action of the first port bend 31, the adapter sealing part 32 and the second port bend 33C, so as to prevent water vapor contained in the gas in the isolation cavity 301 from condensing into water droplets and falling into the energy storage device upon contact with the surface of the inner tube 10.
[0054] The heat-insulating pipe assembly that prevents water vapor condensation also includes a third sealing component 40C. The third sealing component 40C includes a third port closure 41C. The third port closure 41C is disposed at one end of the inner tube body 10 and is adapted to the medium channel 101 to close the port of the medium channel 101.
[0055] In other words, due to the setting of the third port closure 41C, after the coolant enters the medium channel 101, it will pass through at least one of the branch ports 102 and enter at least one of the branch channels 201 in sequence, thereby realizing the branching.
[0056] Preferably, the end of the inner tube 10 near the third port closure 41C extends along the extending direction of the inner tube 10 to form a third receiving portion 11C. The third port closure 41C is disposed at the third receiving portion 11C and closes the port of the medium channel 101. The third sealing member 40C further includes a third wrapping member 42C. The third wrapping member 42C covers the third receiving portion 11C in the circumferential direction, and the end of the third wrapping member 42C along the extending direction of the inner tube 10 is fixedly connected to the third port closure 41C.
[0057] As an example, by applying high temperature to the third sealing member 40C, the third port closure 41C of the third sealing member 40C is fused to the third receiving portion 11C, and the third wrapping member 42C is fused to the outer periphery of the third receiving portion 11C, so as to close the port of the medium channel 101 through the third port closure 41C. The provision of the third wrapping member 42C can improve the stability of the third port closure 41C when it is fused to the third receiving portion 11C.
[0058] Specifically, in this modified embodiment, the diversion component 20 is implemented as including a saddle connector, the diversion component 20 is welded to the inner tube body 10 at high temperature, and the adapter portion 302 is a saddle-shaped hole adapted to the diversion component 20. The inner circumference of the saddle-shaped hole of the adapter portion 302 is bent toward the inner tube body 10 to form the adapter sealing portion 32. As a variant, such as Figure 12 and Figure 13 As shown, the diversion component 20 includes a socket weld tee connector. The inner tube 10 and the outer tube 30 are both divided into two sections. Similarly, each of the two outer tube sections 30 has an adapter 302. The two inner tube sections 10 are respectively inserted into the diversion component 20 and welded to the diversion component 20 at high temperature. The adapter 302 is an annular tube that is adapted to the outer periphery of the connector of the diversion component 20 inserted by the inner tube 10 and is coaxial with the inner tube 10. The adapter 302 is bent toward the inner tube 10 to form the adapter sealing part 32.
[0059] To enable those skilled in the art to understand this application, in at least one embodiment of this application, only [the following is used] Figures 1 to 3 The heat-insulating pipe assembly shown, which prevents water vapor condensation, also includes the first sealing component 40A as an example for illustration.
[0060] In this embodiment, the isolation cavity 301 is a closed environment.
[0061] Alternatively, the isolation cavity 301 can be a vacuum. Compared to an air-filled isolation cavity 301, since air has better thermal conductivity than a vacuum environment, the vacuum isolation cavity 301 can better block heat conduction from the external environment of the outer tube 30.
[0062] like Figure 3 As shown, preferably, the heat-insulating pipe assembly that prevents water vapor condensation further includes at least two support ribs 50. The at least two support ribs 50 are evenly distributed within the insulation cavity 301, and each support rib 50 is connected to both the inner tube body 10 and the outer tube body 30, so that the outer tube body 30 is stably held around the outer periphery of the inner tube body 10 by the support ribs 50. In other words, the outer tube body 30 is stably fitted around the outer periphery of the inner tube body 10 by the at least two support ribs 50, so that the insulation cavity 301 is stably formed between the outer tube body 30 and the inner tube body 10, and the inner tube body 10 is stably isolated from the outside air by the insulation cavity 301.
[0063] Preferably, the support rib 50 is disposed in the isolation cavity 301 in such a way that it extends along the extension direction of the inner tube 10, so as to stably form the isolation cavity 301 on the outer periphery of the inner tube 10 in the extension direction.
[0064] Preferably, the inner tube 10 and the outer tube 30 are made of polymer materials such as nylon, PE, PPH, and PVC, including but not limited to those made of nylon, PE, PPH, and PVC.
[0065] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented.
