Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and in particular to a segmented combined dual heating tube using ceramic-aluminum. Background Technology

[0002] In the context of the booming new energy vehicle industry, batteries, as core energy storage components, are significantly affected by temperature. The temperature control of the battery fluid is crucial to battery performance, lifespan, and safety. Taking lithium-ion batteries as an example, in low-temperature environments, the internal chemical reaction rate slows down, the viscosity of the battery fluid increases, and ion conduction is hindered, leading to battery capacity decay, reduced charging and discharging efficiency, and increased internal resistance, severely impacting the driving range and charging speed of new energy vehicles. To overcome these problems, it is necessary to effectively heat the battery fluid to maintain its temperature within a suitable range, ensuring battery performance.

[0003] Traditional battery fluid heating uses a single heating element. The contact area between the single heating element and the battery fluid is limited, and the battery fluid can only exchange heat with the heating element in a single path. This results in a slow heat transfer rate and a long time required for the battery fluid to heat up. It cannot quickly meet the temperature requirements of the battery in low-temperature environments. In addition, because there is only one heating element, the area closer to the heating element receives more heat during the flow of the battery fluid, while the area farther away from the heating element receives less heat. This can easily lead to local overheating or undercooling, resulting in uneven overall temperature of the battery fluid. Utility Model Content

[0004] The purpose of this invention is to solve the problems of limited contact area between the single heating tube and the battery fluid, and uneven heating, in the existing battery fluid heating method, and to propose a segmented combination of ceramic-aluminum dual heating tubes.

[0005] To achieve the above objectives, the present invention employs the following technology: a segmented combined dual heating tube using ceramic-aluminum, comprising a first tube and a second tube arranged in parallel, the first tube and the second tube being connected by a connecting pipe, the bottom of the first tube being provided with an inlet pipe connected thereto for filtering battery fluid, the bottom of the second tube being provided with an outlet pipe connected thereto, and both the first tube and the second tube being provided with heating components capable of efficiently and uniformly heating the flowing battery fluid.

[0006] As a further description of the above technical solution: the heating component includes a metal tube disposed in the first tube body and the second tube body, wherein an electric heating rod is disposed inside the metal tube, and a spiral heating plate is disposed outside the metal tube.

[0007] As a further description of the above technical solution: the heating element has a first connecting section that fits into the metal tube, and a second connecting section that fits into the inner wall of the first tube and the second tube, wherein the height of the first connecting section is greater than the height of the second connecting section.

[0008] As a further description of the above technical solution: the metal tube is detachably installed at the axial position of the first tube body and the second tube body via a mounting block.

[0009] As a further description of the above technical solution: the two ends of the connecting pipe are detachably connected to the first pipe body and the second pipe body respectively through the upper end cap.

[0010] As a further description of the above technical solution: the inlet pipe and the outlet pipe are detachably connected to the first pipe body and the second pipe body respectively through the lower end cap.

[0011] As a further description of the above technical solution: both the upper and lower end caps are made of aluminum, and both the first tube and the second tube are made of ceramic.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] The two heating tubes increase the contact area with the battery fluid and the heating path length, allowing the battery fluid to absorb heat more fully during flow, resulting in better heat transfer and improved heating efficiency. This allows the battery fluid to be heated to the required temperature more quickly. As the battery fluid flows through the two heating tubes in sequence, it undergoes two heating processes, which reduces local temperature differences and makes the overall temperature of the battery fluid more uniform. This avoids overheating or undercooling in some areas and is beneficial to the stability and consistency of battery performance.

[0014] In addition, the trapezoidal cross-section of the heating element further increases the contact area between the heating element and the fluid, allowing for heat exchange with more fluid in the same space, thereby improving the efficiency of heat transfer. Attached Figure Description

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-4 This embodiment provides a segmented combined dual heating tube using ceramic-aluminum, comprising a first tube 1 and a second tube 2 arranged in parallel. The first tube 1 and the second tube 2 are connected by a connecting tube 5. The two ends of the connecting tube 5 are detachably connected to the first tube 1 and the second tube 2 respectively via an upper end cap 3. The bottom of the first tube 1 is provided with an inlet pipe 6 that is connected to it for filtering battery fluid. The bottom of the second tube 2 is provided with an outlet pipe 7 that is connected to it. The inlet pipe 6 and the outlet pipe 7 are detachably connected to the first tube 1 and the second tube 2 respectively via a lower end cap 4. Both the first tube 1 and the second tube 2 are provided with heating components 8 that can efficiently and uniformly heat the flowing battery fluid.

[0023] In this invention, when the battery fluid needs to be heated, the heating components 8 in the first tube 1 and the second tube 2 are activated for electric heating. Driven by the pump, the battery fluid of the new energy battery enters the first tube 1 through the inlet pipe 6 of the lower end cap 4. At this time, the heating components 8 in the first tube 1 heat the battery fluid in the first stage. After being heated in the first tube 1, the battery fluid, driven by the pump, enters the second tube 2 through the connecting pipe 5 of the upper end cap 3, and then continues to be heated by the heating components 8 in the second tube 2. Finally, it is discharged through the drain pipe 7 at the bottom of the second tube 2. The battery fluid circulates under the action of the pump. The first tube 1 and the second tube 2 are heated by the flow of the battery fluid. The first tube 1 and the second tube 2 are connected in a segmented combination by the connecting tube 5. The two heating tubes increase the contact area with the battery fluid and the heating path length, so that the battery fluid can absorb heat more fully during the flow process, and the heat transfer effect is better, thereby improving the heating efficiency and heating the battery fluid to the required temperature more quickly. The battery fluid flows through the two heating tubes in sequence, which is equivalent to undergoing two heating processes. This can reduce local temperature differences and make the overall temperature of the battery fluid more uniform, avoiding overheating or undercooling in some areas, which is conducive to the stability and consistency of battery performance.

[0024] It should be noted that both the upper end cover 3 and the lower end cover 4 are made of aluminum, while the first tube body 1 and the second tube body 2 are made of ceramic. Aluminum has high strength, which can effectively withstand the pressure of the battery fluid inside the heating tube and the external forces that may be subjected to during use, while ensuring the structural stability of the upper end cover 3 and the lower end cover 4. In addition, aluminum has a relatively low density, which makes the entire heating tube lighter and easier to install and maintain. The ceramic material of the tube body has good insulation, which can effectively prevent current leakage inside the heating tube and prevent electrical short circuits between the battery fluid and the heating structure. Moreover, ceramic has high high temperature resistance and can withstand the high temperature generated by the heating component 8 without deformation or damage.

[0025] Specifically, such as Figures 2-4 As shown, the heating assembly 8 includes a metal tube 81 disposed in the first tube 1 and the second tube 2. The metal tube 81 is detachably installed on the axial position of the first tube 1 and the second tube 2 via a mounting block 82. An electric heating rod 83 is disposed inside the metal tube 81, and a spiral heating plate 84 is disposed outside the metal tube 81.

[0026] The spiral heating element 84 is connected to the metal tube 81. When the battery fluid enters the heating tube under the action of the pump, the heating rod 83 starts heating and transfers heat to the heating element 84. During the process of heating the battery fluid in contact with the heating element 84, the spiral heating element 84 can contact the battery fluid with a larger area, which greatly increases the contact perimeter and area with the battery fluid, so that the heat can be transferred to the battery fluid more fully and improve the heating efficiency. The metal tube 81 of the heating component 8 can be detachably installed in the tube body through several mounting blocks 82, which facilitates the maintenance of the heating component 8. Moreover, the mounting blocks 82 can make the metal tube 81 have space between its two ends and the tube body for the battery fluid to flow. The metal tube 81 will not cause the tube body to be blocked, ensuring that the battery fluid can enter the first tube body 1 and the second tube body 2 and fully contact the heating element 84.

[0027] It should be noted that the heating element 84 has a first connecting section 841 that fits into the metal tube 81, and a second connecting section 842 that fits into the inner wall of the first tube body 1 and the second tube body 2. The height of the first connecting section 841 is greater than the height of the second connecting section 842. The cross-section of the spiral heating element 84 gradually decreases from the metal tube 81 outwards, making the cross-section of the heating element 84 trapezoidal. The spiral heating element 84 itself increases the contact area with the battery fluid inside the tube, and the trapezoidal design further increases the contact area between the heating element 84 and the battery fluid. In the same space, it can exchange heat with more battery fluid, thereby improving the efficiency of heat transfer and enabling the battery fluid to absorb heat more quickly and achieve rapid heating.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
