Description

Technical Field

[0001] This utility model belongs to the field of liquid-cooled charging, and in particular relates to a liquid-cooled pipe with a double-layer reinforced structure. Background Technology

[0002] With the rapid development of new energy vehicles and the continuous improvement of supporting infrastructure, how to complete charging quickly and effectively has become a new challenge. The use of liquid-cooled charging pile cables can effectively alleviate these problems. Liquid-cooled charging pile cables consist of a circulation channel between the cable and the charging gun, using a liquid-cooling pipe. Coolant is added to the liquid-cooling pipe, and a power pump drives the liquid circulation to carry away heat, thus achieving heat dissipation and meeting the requirements of high-power, fast charging. However, in actual use, the service life of liquid-cooled charging pile cables is greatly reduced due to coolant corrosion, high-temperature aging of the liquid-cooling pipe during charging, and contact between the conductor and the liquid-cooling pipe during charging. Therefore, a new device needs to be designed. Utility Model Content

[0003] The purpose of this invention is to provide a liquid cooling pipe with a double-layer reinforced structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A liquid cooling pipe with a double-layer reinforced structure includes an inner tube layer, a braided layer on the outer periphery of the inner tube layer, an outer tube layer on the outer periphery of the braided layer, and a plurality of skeleton reinforcing strips evenly distributed on the inner surface of the inner tube layer. The skeleton reinforcing strips are inclined along the axial direction of the inner tube layer to guide the coolant to rotate and flow. Each skeleton reinforcing strip has a plurality of through grooves evenly distributed on it to guide the coolant to exchange and mix between the skeleton reinforcing strips.

[0006] Furthermore, the reinforcing strip of the skeleton is made of modified nylon material with a thickness of 0.2 mm in width and 0.2 mm in height, which can effectively prevent the conductor under high temperature when moving after charging from touching the inner tube layer, causing aging and damage.

[0007] Furthermore, the through groove is 2 cm long and is set at 30 cm intervals along the length of the skeleton reinforcing strip to facilitate the flow, exchange and mixing of coolant between the skeleton reinforcing strip.

[0008] Furthermore, the inner tube layer is made of modified nylon material with a hardness of 90A, and the skeleton reinforcing strip and the inner tube layer are integrally formed, which improves the resistance to silicone oil corrosion and high temperature aging performance.

[0009] Furthermore, the braided layer is made of DuPont fiber filaments with a braiding density of 50%, which improves the overall tensile and compressive strength without affecting the tight connection between the inner tube layer and the outer tube layer.

[0010] Furthermore, the outer tube layer is also made of modified nylon material with a hardness of 90A, which reduces the risk of high-temperature aging and improves service life during use.

[0011] Compared with existing technologies, the beneficial effects are:

[0012] 1. By using a reinforcing strip to block the conductor from contacting the inner tube layer, high-temperature aging and damage are reduced, and service life is extended.

[0013] 2. By setting the reinforcing bars along the axial direction of the inner tube layer, the overall strength is improved, and the coolant is guided to rotate and flow, so that the coolant is heated more evenly.

[0014] 3. The uniformly spaced through slots facilitate the exchange and mixing of coolant between the reinforcing bars 4, thereby improving the uniformity of cooling. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-2 A liquid cooling pipe with a double-layer reinforced structure includes an inner tube layer 1, a braided layer 2 around the outer periphery of the inner tube layer 1, an outer tube layer 3 around the outer periphery of the braided layer 2, and a plurality of skeleton reinforcing strips 4 evenly distributed on the inner surface of the inner tube layer 1. The skeleton reinforcing strips 4 are inclined along the axial direction of the inner tube layer 1 to guide the coolant to rotate and flow. Each skeleton reinforcing strip 4 has a plurality of through grooves 5 evenly distributed on it to guide the coolant to exchange and mix between the skeleton reinforcing strips 4.

[0020] Furthermore: the skeleton reinforcing strip 4 is made of modified nylon material, with a thickness of 0.2 mm in width and 0.2 mm in height, which can effectively prevent the conductor at high temperature from touching the inner tube layer 1 during movement after charging, thus preventing aging and damage; the through groove 5 is 2 cm long and is set at intervals of 30 cm along the length of the skeleton reinforcing strip 4, which facilitates the flow, exchange and mixing of coolant between the skeleton reinforcing strips 4; the inner tube layer 1 is made of modified nylon material with a hardness of 90A, and the skeleton reinforcing strip 4 and the inner tube layer 1 are integrally formed, which improves the resistance to silicone oil corrosion and high temperature aging performance; the braided layer 2 is made of DuPont fiber filaments with a braiding density of 50%, which improves the overall tensile and compressive strength without affecting the tight connection between the inner tube layer 1 and the outer tube layer 3; the outer tube layer 3 is also made of modified nylon material with a hardness of 90A, which reduces the risk of high temperature aging during use and improves service life.

[0021] Working principle: During charging, the conductor passes through the inner tube layer 1 under the support of the skeleton reinforcing strip 4. At the same time, the coolant, guided by the skeleton reinforcing strip 4, rotates and flows between the inner tube layer 1 and the conductor. When passing through the through groove 5, it exchanges and mixes between the skeleton reinforcing strip 4, making the coolant heat up more evenly and the conductor cools more evenly and consistently. When charging ends and the conductor moves, the conductor at a high temperature is blocked by the skeleton reinforcing strip 4 and cannot touch the inner tube layer 1 to avoid aging and damage, thus extending its service life.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
