Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a cable, a vehicle and a charging device. Background Art

[0002] Cables generate heat during electrical energy transmission, primarily due to energy loss caused by the electrical resistance of the conductors. If this heat cannot be effectively dissipated, it can cause the cable temperature to rise, affecting its performance and lifespan. In severe cases, it can even cause safety hazards such as fires. Therefore, existing technologies integrate cooling cables with power cables, allowing heat generated by the power cables to be transferred to the cooling cables, thereby achieving cable cooling.

[0003] In the existing technology, a cooling cable is added near each power cable to dissipate heat. However, the contact area between two adjacent cables is extremely small, the heat exchange efficiency is low, and the heat dissipation effect is poor. In order to ensure the cooling effect of the power cable, multiple cooling cables need to be filled, which increases the manufacturing cost and difficulty of the cable, and makes the entire cable very thick, which is inconvenient to install and use.

[0025] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0026] Reference below Figure 1-Figure 3 The cable 100 according to the embodiment of the present invention is described. The cable 100 in the embodiment of the present invention can be applied to a vehicle. The cable 100 in the embodiment of the present invention can also be applied to a charging device.

[0027] Combine Figure 1 and Figure 2 As shown, the cable 100 according to an embodiment of the present invention may mainly include: an insulating sleeve 10, a conductive part 20 and a cooling part 30, wherein the conductive part 20 and the cooling part 30 are both arranged in the insulating sleeve 10, and the cooling part 30 is in direct contact with the conductive part 20 to cool the conductive part 20.

[0028] Specifically, on the one hand, the insulating sleeve 10 can be used to protect the internal structure of the cable 100 to prevent water and dust from contaminating the conductive part 20 and the cooling part 30. On the other hand, the insulating part can provide a stable and reliable setting position for the conductive part 20 and the cooling part 30, so that the cooling part 30 and the conductive part 20 are arranged adjacent to each other in the cable 100, so that the cooling part 30 can contact the conductive part 20 inside the cable 100.

[0029] Furthermore, the main function of the conductive member 20 in the cable 100 is to transmit electrical energy. In the embodiment of the present invention, the conductive member 20 includes but is not limited to metal materials such as copper.

[0030] During the process of electric energy transmission, the conductive part 20 generates heat, and the coolant in the cable 100 can be in direct contact with the conductive part 20, so that the coolant in the cable 100 does not need to flow to other high-voltage components, and the insulating layer set between the conductive part 20 and the cooling part 30 in the prior art can be omitted, and the insulation requirement between the coolant and the conductive part 20 can be cancelled.

[0031] Such a setting can not only allow the heat generated by the conductive part 20 during operation to be directly transferred to the cooling part 30 to speed up the rate of heat transfer from the conductive part 20 to the coolant, but also reduce the insulation setting between the cooling part 30 and the conductive part 20, thereby reducing the cost and design difficulty of the cable 100, and making the cable 100 thinner to facilitate the installation and use of the cable 100.

[0032] Furthermore, in an embodiment of the present invention, the conductive member 20 can be in direct contact with the cooling member 30, which can increase the contact area between the conductive member 20 and the cooling member 30, which is beneficial to improving the heat exchange efficiency of the conductive member 20 and the cooling member 30, thereby improving the heat dissipation efficiency of the cable 100, and can improve the heat dissipation effect of the cable 100 in the embodiment of the present invention.

[0033] In an embodiment of the present invention, the cooling element 30 includes, but is not limited to, a coolant. The coolant is disposed within the insulating sleeve 10 and does not circulate, so it does not need to flow to other components for heat exchange. Consequently, the coolant does not require insulation treatment, thereby eliminating the insulating layer between the coolant and the conductive element 20 in the prior art. Furthermore, the heat in the coolant can be transferred through the insulating sleeve 10 to the surrounding environment of the cable 100. For a relatively short period of time, the large amount of heat generated by the transmission of the extremely high current in the cable 100 can be stored within the cable 100 for a short period of time. After the transmission is completed, the heat of the coolant in the cable 100 can be gradually released into the surrounding air.

[0034] Because the cable 100 in the embodiment of the present invention has a short operating time and a long non-operating time, the heat in the coolant can be completely released into the air during the non-operating time of the cable 100. Therefore, before the cable 100 is put into operation again, the temperature of the coolant can be reduced and restored, and the large amount of heat generated by the conductive member 20 can be reabsorbed. Thus, the embodiment of the present invention utilizes the heat dissipation time of the cooling member 30 in exchange for the cooling space of the cooling member 30, eliminating the need for a flow design of the cooling member 30 and allowing the cooling member 30 to be in direct contact with the conductive member 20, thereby reducing the cooling cost and design difficulty of the cable 100.

[0035] According to some embodiments of the present invention, Figure 1As shown, the conductive member 20 is circumferentially arranged on the outside of the cooling member 30 and is in contact with the cooling member 30. Specifically, the insulating sleeve 10, the conductive member 20, and the cooling member 30 of the cable 100 are generally arranged in a cylindrical structure, and the insulating sleeve 10, the conductive member 20, and the cooling member 30 are coaxially arranged in the cable 100. The conductive member 20 inside the insulating sleeve 10 is arranged circumferentially around the outside of the cooling member 30, so that the axial inner wall surface of the conductive member 20 and the axial outer wall surface of the cooling member 30 are in contact with each other, thereby increasing the contact area between the conductive member 20 and the cooling member 30, thereby improving the heat exchange efficiency of the conductive member 20 and the cooling member 30.

[0036] According to other embodiments of the present invention, Figure 2 As shown, the cooling member 30 circumferentially surrounds the outside of the conductive member 20 and is in contact with the conductive member 20. Specifically, the insulating sleeve 10, the conductive member 20, and the cooling member 30 of the cable 100 are generally configured as cylindrical structures, and the insulating sleeve 10, the conductive member 20, and the cooling member 30 are coaxially arranged in the cable 100. The cooling member 30 inside the insulating sleeve 10 is configured to circumferentially surround the outside of the conductive member 20. This allows the axial inner wall surface of the cooling member 30 to be in contact with the axial outer wall surface of the conductive member 20, thereby increasing the contact area between the conductive member 20 and the cooling member 30, thereby improving the heat exchange efficiency of the conductive member 20 and the cooling member 30.

[0037] According to an embodiment of the present invention, the specific heat capacity of water is set to α, and the specific heat capacity of the cooling element 30 is set to β, and the relationship between β and α is: β ≥ α. Specifically, the specific heat capacity of the cooling element 30 in the cable 100 in the embodiment of the present invention is set to be no less than the specific heat capacity of water. This allows the cooling element 30 in the embodiment of the present invention to have a larger heat storage capacity, allowing the cooling element 30 to store more heat in a shorter period of time, thereby improving the heat absorption capacity of the cooling element 30 and enhancing the heat dissipation performance of the cable 100.

[0038] Furthermore, in an embodiment of the present invention, the cooling element 30 includes but is not limited to water, ethylene glycol-based coolant and hydrofluoroether. Specifically, the ethylene glycol-based coolant is a solution made by mixing ethylene glycol or propylene glycol with water in a specific ratio. Different ratios of ethylene glycol or propylene glycol to water can make the ethylene glycol-based coolant have different freezing points, wherein the freezing point of a mixture of 10% ethylene glycol and 90% pure water is -3.4°C, the freezing point of a mixture of 40% ethylene glycol and 60% pure water is -25.0°C, the freezing point of a mixture of 50% ethylene glycol and 50% pure water is -35.0°C, and the freezing point of a mixture of 60% ethylene glycol and 40% pure water is -52.8°C. With this arrangement, the ethylene glycol-based coolant can adapt to low temperature environments, thereby preventing the cooling element 30 from solidifying when the temperature is too low and squeezing the conductive element 20 and / or the conductive cavity 11 structure.

[0039] Furthermore, hydrofluoroether is a type of organic solvent that is insulating, colorless, odorless, and has low toxicity. It is commonly used in cooling electronic circuits. Using hydrofluoroether as the coolant for the cable 100 of the present invention is easy to obtain and highly safe.

[0040] According to an embodiment of the present invention, the cooling member 30 is a phase change material cooling member. The phase change material can change from one physical state to another physical state. During the transformation of the physical form of the phase change material, the cooling member 30 can absorb heat. In this way, the cooling member 30 can absorb the heat generated during the operation of the conductive member 20, so as to cool the conductive member 20, thereby realizing heat dissipation of the cable 100.

[0041] In some embodiments of the present invention, the phase change material in the phase change material cooling element includes but is not limited to rubber and silicone materials. The solid phase change material at room temperature can be attached to the conductive element 20. By applying other thermal conductive materials, a system with high specific heat capacity can be formed, thereby achieving a high current carrying function of the cable 100 in a shorter time.

[0042] In other embodiments of the present invention, the phase change material in the phase change material cooling element may be an insulating liquid, wherein the insulating liquid includes but is not limited to oil. Using insulating liquid as the cooling element 30 can not only increase the specific heat capacity of the cooling element 30, so that the cable 100 has a high current-carrying function in a shorter time, but also prevent the current from passing through the cooling element 30, thereby reducing the resistance encountered by the current when it is transmitted in the cable 100, thereby reducing the heat generation of the cable 100 and reducing the heat dissipation pressure of the cable 100.

[0043] In an embodiment of the present invention, the cooling member 30 includes but is not limited to a cooling material with a high thermal conductivity. The cooling material with a high thermal conductivity can transfer heat faster inside the cooling member, which can speed up the rate of heat transfer from the conductive member 20 to the cooling member 30, speed up the rate of heat transfer in the cooling member 30, and further increase the rate of heat release from the cooling member 30 to the surrounding environment, thereby helping to improve the heat dissipation efficiency of the cable 100 and improving the heat dissipation effect of the cable 100.

[0044] Combine Figure 1-Figure 3 As shown, a conductive cavity 11 is provided in the insulating sleeve 10, and the conductive part 20 and the cooling part 30 are both provided in the conductive cavity 11. The insulating sleeve 10 is at least partially provided with a coolant compensation cavity 12 protruding away from the conductive cavity 11, and the coolant compensation cavity 12 is communicated with the conductive cavity 11.

[0045] In the conductive cavity 11, according to the actual usage, a coolant compensation cavity 12 can be appropriately set at the place where the coolant demand is high, so as to absorb more heat. The main calculation method is as follows; Assume that the conductivity of the cable 100 is ρ, the current transmitted in the cable 100 is I, the radial cross-sectional area of the cable 100 is A, and the heat generated per unit length of the cable 100 is Q. Then ρ, I, A, and Q satisfy the relationship: Q=ρ·I·I·A, where the unit of Q is W / m.

[0046] During the specified charging time, this heat will exist in the cable 100 in the form of hot melt of liquid, and the liquid is required not to liquefy. Assume that the mass of the coolant is M, the specific heat capacity of the coolant is S, and the temperature change (i.e., temperature difference) of the coolant during the specified charging time is T. Then M, S, T, ρ, I, A and Q satisfy the relationship, and the total heat of the coolant is: Q = ρ·I·I·A = M·S·T.

[0047] Under the ultra-large current of super-fast charging, the heat generated in the cable 100 is relatively high, and the temperature change of the coolant is limited. Under a certain temperature change, the volume of the coolant needs to be increased to meet the heat dissipation requirements of the conductive part 20. Therefore, in the embodiment of the present invention, a coolant compensation cavity 12 is at least partially provided on the insulating sleeve 10, which is protruded away from the conductive cavity 11. That is, the coolant compensation cavity 12 is added in an appropriate area of the conductive cavity 11 to ensure that the amount of coolant in the conductive cavity 11 is sufficient, thereby ensuring the heat dissipation effect of the cable 100.

[0048] According to some embodiments of the present invention, when the conductive member 20 is circumferentially arranged on the outside of the cooling member 30 and is in contact with the cooling member 30, the coolant compensation cavity 12 protruding from the conductive cavity 11 on the insulating sleeve 10 passes through the conductive member 20 and extends into the cooling member 30. In this way, while ensuring that the conductive member 20 is circumferentially arranged on the outside of the cooling member 30, the coolant compensation cavity 12 can be connected to the cooling member 30, and the coolant in the coolant compensation cavity 12 and the coolant in the cooling member 30 can circulate with each other, so as to achieve coolant compensation for the local locations with higher heat generation in the cable 100.

[0049] According to other embodiments of the present invention, when the cooling member 30 is circumferentially arranged around the outside of the conductive member 20 and is in contact with the conductive member 20, the cooling liquid compensation chamber 12 protruding away from the conductive cavity 11 on the insulating sleeve 10 is arranged close to the cooling member 30, and the cooling liquid compensation chamber 12 is directly connected to the cooling member 30, so that the cooling liquid in the cooling liquid compensation chamber 12 and the cooling liquid in the cooling member 30 can circulate with each other, so as to perform cooling liquid compensation on the local locations with higher heat generation in the cable 100.

[0050] In an embodiment of the present invention, Figure 3 As shown, there are multiple coolant compensation cavities 12, which are spaced apart on the insulating sleeve 10. Specifically, to meet the heat dissipation requirements of the cable 100 when ultra-high current passes through, the insulating sleeve 10 of the cable 100 in the embodiment of the present invention is provided with multiple coolant compensation cavities 12 to increase the coolant compensation amount in the conductive cavity 11. This can increase the ability of the cooling element 30 to absorb heat from the conductive element 20, thereby improving the heat dissipation effect of the cable 100.

[0051] Furthermore, multiple coolant compensation chambers 12 are arranged at intervals on the insulating sleeve 10, so that the multiple coolant compensation chambers 12 can be evenly arranged in the insulating sleeve 10, so that coolant compensation can be performed on different positions in the conductive cavity 11, and the compensated coolant can be evenly distributed along the axial direction of the conductive cavity 11, so that the distance from the heating position on the conductive part 20 to the coolant compensation chamber 12 can be shortened, and the heat in the coolant compensation chamber 12 can be transferred to the coolant faster, so as to increase the rate of heat transfer from the conductive part 20 to the cooling part 30, thereby improving the heat dissipation efficiency of the cable 100.

[0052] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, a conductive cavity 11 is provided in the insulating sleeve 10, and the conductive member 20 and the cooling member 30 are both provided in the conductive cavity 11. The outer surface of the insulating sleeve 10 is provided with a conductive cavity volume compensation cavity 13 protruding away from the conductive cavity 11, and the conductive cavity volume compensation cavity 13 is communicated with the conductive cavity 11. Specifically, when the ambient temperature of the cable 100 is too low and reaches the solidification temperature of the coolant, the coolant in the conductive cavity 11 may solidify, which will cause the coolant to change from liquid to solid and increase in volume. Therefore, a conductive cavity volume compensation cavity 13 protruding away from the conductive cavity 11 is provided on the outer surface of the insulating sleeve 10. The conductive cavity volume compensation cavity 13 increases the space in the conductive cavity 11 where the coolant can be set. After the coolant solidifies and increases in volume, part of the coolant can expand into the conductive cavity volume compensation cavity 13. This can effectively solve the problem caused by the increase in the volume of the coolant in the conductive cavity 11 and prevent the liquid from solidifying and expanding and damaging the structure of the cable 100 or the conductive cavity 11.

[0053] Combine Figure 3As shown, the conductive cavity volume compensation cavity 13 and the coolant compensation cavity 12 are spaced apart from each other. This arrangement allows the conductive cavity volume compensation cavity 13 and the coolant compensation cavity 12 to be independently arranged on the insulating sleeve 10, thereby ensuring the structural reliability of the conductive cavity volume compensation cavity 13 and the coolant compensation cavity 12 on the insulating sleeve 10 and ensuring the integrity of the functions of the conductive cavity volume compensation cavity 13 and the coolant compensation cavity 12. In this way, on the one hand, when the current transmitted in the cable 100 is an ultra-high current, the coolant in the conductive cavity 11 can absorb more heat generated in the cable 100 to ensure the temperature stability of the cable 100. On the other hand, in a low temperature environment, after the coolant solidifies and expands in volume, it can fill the conductive cavity volume compensation cavity 13, thereby preventing the coolant volume from increasing and squeezing the conductive member 20. In this way, the working reliability of the cable 100 can be ensured. The volume of the conductive cavity volume compensation cavity 13 can be determined based on the volume increment of the coolant after solidification.

[0054] In an embodiment of the present invention, Figure 3 As shown, there are multiple conductive cavity volume compensation cavities 13, and the multiple conductive cavity volume compensation cavities 13 are arranged at intervals on the insulating sleeve 10. Such an arrangement can not only provide more expandable space for the volume of the coolant after solidification in the conductive cavity 11 to meet the demand for volume expansion of the coolant after solidification, but also avoid the coolant volume expansion squeezing the cable 100. Moreover, after calculating the volume increment of the coolant after solidification, the total volume increment of the coolant after solidification can be allocated to each conductive cavity 11 volume supplement cavity, so that each conductive cavity 11 volume supplement cavity can be arranged in the insulating sleeve 10, which can avoid increasing the radial size of the insulating sleeve 10 due to the excessive size of a single conductive cavity 11 volume supplement cavity, thereby preventing the cable 100 from being thickened, and facilitating the installation and use of the cable 100.

[0055] According to other embodiments of the present invention, at least a portion of the insulating sleeve 10 is a deformable flexible portion. Specifically, the deformable flexible portion is a portion of the insulating sleeve 10 with a certain degree of deformation, and the deformable flexible portion will deform to a certain extent when subjected to a certain amount of pressure.

[0056] In this way, in a low-temperature environment, if the coolant expands in volume after solidification, the expanded coolant can squeeze the deformable flexible part on the insulating sleeve 10, squeeze the position of the insulating sleeve 10 corresponding to the deformable flexible part in a direction away from the conductive cavity 11, and make the deformable flexible part protrude from the insulating sleeve 10. In this way, not only can the setting of the coolant compensation cavity 12 and the conductive cavity volume compensation cavity 13 on the insulating sleeve 10 be eliminated, which is conducive to simplifying the processing method of the insulating sleeve 10, but also the increased volume of the coolant can be released to prevent the coolant from increasing in volume after solidification or vaporization and causing squeezing of the conductive part 20, thereby ensuring the structural reliability of the cable 100.

[0057] According to some further embodiments of the present invention, the coolant is refined in the conductive cavity 11, for example, brine is added to the coolant to lower the solidification temperature of the coolant, thereby eliminating the provision of the conductive cavity volume compensation cavity 13 on the insulating sleeve 10, thereby simplifying the processing and production of the insulating sleeve 10, and facilitating improving the production efficiency of the cable 100.

[0058] Combine Figure 3 As shown, a temperature sensor 40 is provided in the insulating sleeve 10. Specifically, the temperature sensor 40 can be provided in the conductive cavity 11 to detect the temperature in the conductive cavity 11 in real time. In this way, a temperature protection strategy can be designed based on the real-time temperature in the conductive cavity 11, thereby controlling and preventing the phase change of the coolant. This can prevent the coolant from absorbing too much heat and vaporizing, thereby increasing the pressure in the conductive cavity 11 and damaging the cable 100. Such a configuration can protect the structural reliability and safety of the cable 100.

[0059] In an embodiment of the present invention, after rigorous calculations and long-term durability tests, the temperature sensor 40 in the insulating sleeve 10 can be eliminated while ensuring that the cable 100 does not cause phase change of the coolant due to excessively high or low temperatures.

[0060] According to an embodiment of the present invention, the cable 100 can be used in a vehicle. The cable 100 in the embodiment of the present invention can be used in a vehicle's output power harness, wherein the vehicle's output power harness includes but is not limited to a harness used for short-term acceleration, such as an output power harness for acceleration between 0 and 100 km / h. Such a harness needs to carry a large amount of power when the vehicle accelerates, and the power decreases as the vehicle speed increases, allowing the cable 100 to dissipate heat naturally.

[0061] Furthermore, the cable 100 in the embodiment of the present invention can also be applied to the charging current-carrying harness of a super-fast charging vehicle. The charging harness of such a vehicle has the characteristics of low current-carrying power and short charging time. The cable 100 in the hybrid vehicle only works during the charging time, and its working time is usually 5 to 10 minutes. After charging is completed, the cable 100 is idle for a long time, and there is sufficient heat dissipation time for the cable 100 to dissipate heat.

[0062] According to an embodiment of the present invention, the cable 100 can be used in a charging device. The cable 100 in the embodiment of the present invention can be used in super-fast charging harnesses, including but not limited to the field of communication equipment. Communication equipment with super-fast charging function has a shorter charging time, and the cable 100 has a longer time to release heat after charging. In addition, the cable 100 in the embodiment of the present invention has a simple structure, a small size, and is easy to carry, making it suitable for charging mobile communication equipment.
