Description

Technical Field

[0001] This utility model relates to the field of cooling hose technology, and in particular to a cooling hose for new energy vehicle batteries. Background Technology

[0002] In the field of new energy vehicles, the battery thermal management system plays a decisive role in battery performance and safety. As a key component for coolant transmission, the battery cooling hose needs to work stably and reliably.

[0003] However, in the existing technology, cooling hoses not only face durability problems caused by high temperature, corrosion and vibration, but also have shortcomings in vehicle frame fixation. Common fixing methods are prone to loosening, causing hose displacement and twisting, affecting the normal delivery of coolant, and even causing leakage. Therefore, a new type of cooling hose for new energy vehicle batteries is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a cooling hose for new energy vehicle batteries, which solves the problems of existing battery cooling hoses being not durable and easily displaced by vehicle vibration.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling hose for a new energy vehicle battery, comprising a hose body, wherein the hose body includes a coolant barrier layer, a strength reinforcement layer, and a protective heat dissipation layer, the strength reinforcement layer is disposed between the coolant barrier layer and the protective heat dissipation layer, the outer wall of the coolant barrier layer is connected to the inner wall of the strength reinforcement layer, the inner wall of the protective heat dissipation layer is connected to the outer wall of the strength reinforcement layer, and a fixing clip is provided on the outer wall of the hose body for fixing.

[0006] Preferably, the coolant barrier layer is made of perfluoroether rubber with a thickness of 2.5-3.5 mm.

[0007] Preferably, the strength-enhancing layer is composed of a high-strength aramid fiber woven mesh and stainless steel wire spirally wound together, with a thickness of 2-3 mm.

[0008] Preferably, the protective heat dissipation layer is made of EPDM rubber modified with nano-scale graphene and anti-aging additives, and has a total thickness of 3-4 mm.

[0009] Preferably, the inner wall of the fixing clamp is provided with a flexible rubber pad for shock absorption, and the side of the flexible rubber pad away from the fixing clamp is provided with an anti-slip strip for anti-slip function.

[0010] Preferably, the anti-slip strips are arranged at equal intervals on the sidewall of the flexible rubber pad.

[0011] Preferably, the upper and lower ends of the fixing clamp are connected by bolts and nuts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By incorporating a perfluoroether rubber coolant barrier layer, the hose can operate stably in high-temperature environments for extended periods, preventing material aging and performance degradation caused by high temperatures. The perfluoroether rubber coolant barrier layer, the nano-graphene-modified protective and heat-dissipating layer, and the PTFE sealing ring provide the hose with extremely strong resistance to chemicals in the coolant. The high-strength aramid fiber braided mesh and stainless steel wire spiral winding composite layer enhance strength and fatigue resistance, while the fiber-reinforced rubber sleeve significantly improves the hose's pressure resistance and bending fatigue resistance. At the same time, the nano-graphene-modified protective and heat-dissipating layer can quickly dissipate heat from inside the hose. The high-strength engineering plastic fixing clip combined with the flexible rubber pad ensures the hose is securely fixed to the frame, effectively preventing hose displacement and twisting.

[0019] 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.

[0020] This utility model relates to a cooling hose for new energy vehicle batteries, such as... Figure 1-4As shown, the device includes a hose body 1, which includes a coolant barrier layer 101. The coolant barrier layer 101 is made of perfluoroether rubber, which can operate stably at high temperatures for extended periods. It exhibits strong resistance to chemical additives in the coolant, and its molecular structure contains a large number of fluorine atoms, resulting in high chemical stability and effective prevention of coolant penetration. This layer has a thickness of 2.5-3.5 mm, ensuring reliable coolant barrier. The outer wall of the coolant barrier layer 101 is provided with a strength reinforcement layer 102, which is composed of a high-strength aramid fiber woven mesh and stainless steel wire spirally wound together. The aramid fiber has high strength, high modulus, and excellent fatigue resistance, enhancing the axial and radial strength of the hose and resisting cold... To reduce liquid pressure and external tensile stress, the spiral winding of stainless steel wire further enhances the resistance to pressure and bending fatigue, preventing the hose from deforming or breaking under stress. This layer has a total thickness of 2-3mm. A protective heat dissipation layer 103 is provided on the outer wall of the strength reinforcement layer 102. The strength reinforcement layer 102 is located between the coolant barrier layer 101 and the protective heat dissipation layer 103. The protective heat dissipation layer 103 is made of EPDM rubber modified with nano-scale graphene and anti-aging additives. EPDM rubber is weather-resistant, ozone-resistant, and water-resistant, protecting the hose from external environmental influences. Nano-scale graphene enhances the material's strength and thermal conductivity, allowing it to better withstand external friction and impact, accelerating heat dissipation from inside the hose, and reducing the operating temperature. Anti-aging additives improve the material's anti-aging properties and extend the hose's service life. This layer has a thickness of 3-4mm.

[0021] Furthermore, for ease of fixation, a fixing clip 2 is provided on the outer wall of the hose body 1. The fixing clip 2 is semi-circular, which facilitates fixing the hose body 1 to the frame. The inner wall of the fixing clip 2 is provided with anti-slip strips 4 that are compatible with the hose body 1. The anti-slip strips 4 are equidistantly arranged on the side wall of the flexible rubber pad 3 to increase friction and prevent the hose from sliding inside the fixing clip. The inner wall of the fixing clip 2 is provided with a flexible rubber pad 3. The flexible rubber pad 3 is made of neoprene rubber, which has good flexibility, aging resistance and shock absorption performance. The thickness of the flexible rubber pad 3 is 2-3mm. Its function is to buffer the impact of the frame vibration on the hose during vehicle operation, avoid damage to the hose due to friction between the hose and the fixing clip 2 caused by vibration, and further enhance the stability of the fixation. The side of the flexible rubber pad 3 away from the fixing clip 2 is provided with anti-slip strips 4. The upper and lower ends of the fixing clip 2 are provided with mounting holes (not shown in the figure). The upper and lower ends of the fixing clip 2 are connected by bolts and nuts 5.
