Description

Technical Field

[0001] This invention relates to the field of automotive batteries, and in particular to a corrosion-resistant and heat-dissipating automotive battery housing. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the performance requirements for automotive battery boxes are becoming increasingly stringent. Battery boxes must not only possess good mechanical strength and corrosion resistance, but also have efficient heat dissipation performance to ensure stable battery operation and extend battery life.

[0003] However, ordinary car battery boxes often have some problems in daily use. With the development of technology, technicians in related fields have also made a lot of optimizations to car battery boxes. For a more accurate comparison, Chinese patent with publication number CN112234299A discloses a battery box housing for new energy electric vehicles, including a main housing, a support base, a cover, a pushing mechanism, a heat dissipation and cooling mechanism, and a locking mechanism. In use, the battery is installed in the main housing, and the cover is locked at the top of the main housing. Then, the locking frame drives the rotating shaft to rotate to lock the top side of the cover. By rotating the fixing bolt, the fixing bolt is fixed to the locking frame and the cover, improving the sealing effect of the cover. At the same time, the heat generated by the battery is discharged through the heat dissipation fins, and the semiconductor cooling chip cools the battery. The heat is discharged through the heat conduction plate and cooled through the water in the cavity, improving the heat dissipation effect. This facilitates auxiliary heat dissipation of the battery placed in the housing, improving the heat dissipation effect and meeting the usage requirements.

[0004] However, the aforementioned car battery packs have some shortcomings in actual use:

[0005] 1. The aforementioned battery box uses a semiconductor cooling chip for cooling, and then uses a heat conduction plate to conduct the heat generated by the battery during operation. At the same time, water is filled into the cavity inside the battery box to cool it down, thus facilitating heat dissipation for the battery inside the casing. However, during use, a large amount of water needs to be pre-filled into the cavity and stored inside the box. After filling the battery box with a large amount of water, the overall weight of the battery box will increase significantly. As a result, the battery inside the battery box will require more power to complete the corresponding operation. More power consumption means more heat will be generated, thus slowing down the efficiency of battery heat dissipation.

[0006] 2. The above-mentioned device uses a semiconductor cooling plate and a heat conduction plate installed at the bottom of the box to dissipate heat from the battery inside the battery box. However, in actual use, the device does not make the heat conduction plate and the semiconductor cooling plate directly contact the outer surface of the battery. Instead, it conducts heat to the water in the cavity to dissipate heat, thereby indirectly conducting and converting the heat generated by the battery. In practical applications, it is difficult to quickly conduct and dissipate the heat generated by the battery in a short period of time, resulting in low efficiency.

[0007] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing automotive battery packs. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides a corrosion-resistant and heat-dissipating automotive battery case housing, comprising a main housing with an opening, a heat dissipation shell sleeved on the outside of the main housing, a cover plate connected to the heat dissipation shell for covering and sealing the main housing, and a radiator for dissipating heat from the battery installed inside the main housing, which is jointly installed between the main housing and the heat dissipation shell. The main housing, the heat dissipation shell, and the cover plate cooperate with each other to form a complete battery case for installing automotive batteries.

[0009] The heat sink includes a heat dissipation cavity formed by a hollow space between the main housing and the heat dissipation shell. Several heat-conducting fins are evenly arranged in the heat dissipation cavity and inserted into the main housing. The heat-conducting fins are evenly distributed on the outer side of the main housing and one end is inserted into the main housing to abut against the outer wall of the battery. A heat-conducting plate is connected to the bottom of the main housing to support the battery and is in contact with the bottom of the battery. The heat-conducting plate is hollow inside for storing medium, and the lower side of the heat-conducting plate is located in the heat dissipation cavity.

[0010] Preferably, a connecting pipe is provided on several heat-conducting sheets located on the same side of the main housing, and the connecting pipe is connected to the heat-conducting plate.

[0011] Preferably, a plurality of connecting tubes are evenly inserted through any of the heat-conducting sheets, and the plurality of connecting tubes on the same side are simultaneously inserted through the plurality of heat-conducting sheets on the same side.

[0012] Preferably, the ends of several connecting pipes on the same side that are away from the heat-conducting plate are connected to a heat-dissipating cylinder. The heat-dissipating cylinder is connected to the inner wall of the heat dissipation shell. All the heat-dissipating cylinders located on the outside of the main shell are interconnected. Several heat dissipation fins that protrude from the heat dissipation shell are evenly connected to the heat-dissipating cylinder.

[0013] Preferably, the heat sinks located on the same heat dissipation cylinder are spaced apart from each other, and a guide groove corresponding to the heat dissipation cylinder is provided on the heat dissipation shell. The guide groove allows airflow to pass through and forms an air channel to dissipate heat from the heat sinks.

[0014] Preferably, multiple guide grooves are provided, and each guide groove corresponds to a heat dissipation cylinder, with both ends of the guide grooves being sloped.

[0015] Preferably, the heat dissipation shell is connected to a plurality of clamping plates for pressing the cover plate.

[0016] Preferably, the heat dissipation shell is further connected with several bent structures and sealing gaskets corresponding to the pressure plate, and the cover plate is located between the pressure plate and the sealing gaskets.

[0017] Preferably, the main housing has a hollow sliding cavity, and a sliding push rod corresponding to the sealing gasket is inserted in the sliding cavity. One end of the sliding push rod that extends out of the sliding cavity is connected to a driven push plate for abutting the sealing gasket. The driven push plate has a bent structure, and the side of its vertical section near the sealing gasket is set as a slope.

[0018] Preferably, the main housing and the heat sink are composite materials combining metal and plastic.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] I. This invention uses a heat-conducting plate and several heat-conducting sheets to contact the car battery, so that the temperature of the side of the heat-conducting plate and heat-conducting sheets in contact with the car battery is higher than the side located in the heat dissipation cavity. At this time, under the trend of high energy to low energy transfer, the high heat at the car battery is transferred to the low heat in the heat dissipation cavity, so that the high heat in the car battery in the main casing gradually decreases, while the low heat in the heat dissipation cavity gradually increases, so as to achieve the effect of heat dissipation for the car battery until the heat in the main casing and the heat dissipation cavity are in equilibrium.

[0021] Second, this invention only requires injecting a medium into the heat-conducting plate. The heat generated during the operation of the car battery causes the medium in the heat-conducting plate to undergo a phase change and vaporize into steam. During the steam formation process, a large amount of heat is absorbed from the heat-conducting plate, thereby achieving the effect of conducting and dissipating heat for the car battery. This effectively avoids the problem of needing to inject more water into the battery box, increasing the load on the car battery, and causing the car battery to generate more heat.

[0022] Third, by setting up several connecting pipes that are connected to the heat-conducting plate, and connecting the ends of the connecting pipes with heat dissipation cylinders and heat sinks, the steam in the connecting pipes can be quickly cooled by the external natural airflow, and the steam can be re-condensed into a liquid medium and then fall back into the heat-conducting plate, thus realizing the reuse effect of the battery box and increasing the practicality of the battery box.

[0023] Fourth, this invention uses a composite material of metal and plastic as the main structure of the battery box shell, taking advantage of the advantages of each to achieve a combination of high performance and durability. The metal part not only enhances the strength of the shell, but also has good heat dissipation performance; the plastic part provides excellent corrosion resistance. This composite material design ensures that the battery can dissipate heat quickly while protecting the battery from external environmental corrosion, thereby extending the battery's service life and ensuring the safe operation of the vehicle.

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1 To be continued Figure 8 The embodiments of the present invention will be described in detail, but the present invention may be implemented in many different ways as defined and covered by the claims.

[0035] This application discloses a corrosion-resistant and heat-dissipating automotive battery housing. The housing is primarily used during the installation and use of automotive batteries. Technically, it achieves a sealed installation of the battery to prevent external moisture from entering and causing corrosion. Especially during normal use after installation, the heat generated by the battery is effectively dissipated through the contact between the heat-conducting plate and several heat-conducting fins. Furthermore, the housing, through its connecting pipes, heat dissipation cylinder, and heat sinks, rapidly cools the vapor within the connecting pipes and heat-conducting plate, thereby achieving rapid cooling of the automotive battery.

[0036] Reference Figure 1 and Figure 2 As shown, a corrosion-resistant and heat-dissipating automotive battery case includes a main housing 1, a heat dissipation shell 10, a cover plate 11, and a radiator 2. The main housing 1 has a quadrilateral structure with an opening. The heat dissipation shell 10 is fitted onto the outside of the main housing 1. The cover plate 11, used to cover and seal the main housing 1, is connected to the heat dissipation shell 10. A radiator 2, used to dissipate heat from the battery installed inside the main housing 1, is installed between the main housing 1 and the heat dissipation shell 10. The main housing 1, the heat dissipation shell 10, and the cover plate 11 cooperate to form a complete battery case for installing automotive batteries. In use, the automotive battery is installed inside the main housing 1, and the main housing 1 is covered by the cover plate 11, completing the sealing and installation of the automotive battery. Then, when the automotive battery is operating, the heat dissipation shell 10 conducts and converts the heat generated by the automotive battery, thereby achieving the effect of dissipating heat from the installed automotive battery.

[0037] Reference Figures 2 to 5 As shown, the heat sink 2 is used to dissipate heat from the battery installed inside the main housing 1. Specifically, the heat sink 2 includes a heat dissipation cavity 20, heat-conducting fins 21, and a heat-conducting plate 22. The heat dissipation cavity 20 is formed in the hollow space between the main housing 1 and the heat dissipation shell 10. Several heat-conducting fins 21 are evenly arranged in the heat dissipation cavity 20 and inserted into the main housing 1. The heat-conducting fins 21 are evenly distributed on the outer side of the main housing 1 and one end is inserted into the main housing 1 to abut against the outer wall of the battery. The bottom of the main housing 1 is connected to a heat-conducting plate 22 for supporting the battery and fitting against the bottom of the battery. The heat-conducting plate 22 is hollow inside for storing the medium. The lower side of the heat-conducting plate 22 is located inside the heat dissipation cavity 20. It should be noted that the heat-conducting plate 22 and the heat-conducting fins 21 are preferably materials with excellent thermal conductivity (such as copper or aluminum), and the medium is preferably a fluid with high thermal conductivity and a suitable boiling point. As an optional implementation, water is used as the working medium in the heat-conducting plate 22 in this embodiment.

[0038] When a car battery is in use, a chemical reaction occurs between its positive and negative electrode materials, releasing electrons and ions. This process is usually accompanied by the release of energy, some of which is dissipated as heat. This causes the temperature at the battery location to rise, making the heat at the car battery location inside the battery box higher than other locations. Due to the contact between the heat-conducting plate 22 and several heat-conducting sheets 21 and the car battery, the temperature on the side of the heat-conducting plate 22 and heat-conducting sheets 21 in contact with the car battery is higher than the side located inside the heat dissipation cavity 20. At this time, under the trend of high energy to low energy transfer, the high heat at the car battery location is transferred to the low heat in the heat dissipation cavity 20. This causes the high heat of the car battery inside the main casing 1 to gradually decrease, while the low heat in the heat dissipation cavity 20 gradually increases, thereby achieving the effect of heat dissipation for the car battery until the heat in the main casing 1 and the heat dissipation cavity 20 are in equilibrium.

[0039] During the process of conducting high heat from the car battery through the heat conduction plate 22, some of the high heat is transferred to the water inside the heat conduction plate 22 after passing through the heat conduction plate 22, thus heating the water inside the heat conduction plate 22. The process of heating the water inside the heat conduction plate 22 completes the absorption and conversion of the heat conducted from the car battery, thereby improving the efficiency of heat dissipation of the car battery.

[0040] Furthermore, as the car battery continues to operate, the heat and temperature generated by the battery also increase and rise continuously. After a period of transfer, as the heat and temperature between the heat dissipation cavity 20 and the main casing 1 gradually reach a relative equilibrium, its efficiency and effect in dissipating heat from the car battery gradually decrease and weaken. Based on this, referring to... Figures 2 to 5 As shown, a connecting pipe 23 is commonly installed on several heat-conducting plates 21 located on the same side of the main housing 1. The connecting pipe 23 is connected to the heat-conducting plate 22 and is located inside the heat dissipation cavity 20. During use, the heat generated by the car battery is conducted to the heat-conducting plate 22 and the water inside the heat-conducting plate 22, causing the water inside the heat-conducting plate 22 to heat up to its boiling point. Then, the water undergoes a phase change and vaporizes into steam. During the process of forming steam, the water absorbs the heat from the heat-conducting plate 22, thereby achieving the effect of heat dissipation for the heat-conducting plate 22 and the car battery.

[0041] After the water inside the heat-conducting plate 22 is converted into water vapor during the phase change process, the water vapor rises along the connecting pipe 23 connected to the heat-conducting plate 22 because the density of water vapor is usually lower than that of air. During the rising process, the water vapor absorbs and converts the heat of the heat-conducting sheet 21 connected to the connecting pipe 23, thereby achieving the effect of heat dissipation on the side wall of the battery.

[0042] Reference Figures 2 to 5As shown, several connecting pipes 23 are evenly distributed on any heat-conducting plate 21, and several connecting pipes 23 on the same side are simultaneously distributed on several heat-conducting plates 21 on the same side. In use, water vapor is guided through several connecting pipes 23 that are connected to the heat-conducting plate 22. As the water vapor rises along the connecting pipes 23, it also conducts heat to the heat-conducting plates 21 connected to the connecting pipes 23, thereby accelerating the heat dissipation effect of the heat-conducting plate 22 and the heat-conducting plates 21.

[0043] Furthermore, in order to recycle the water that has been converted into steam and thus save costs, refer to Figures 2 to 5 As shown, several connecting pipes 23 on the same side, with their ends away from the heat-conducting plate 22, are connected to a heat-dissipating cylinder 24. The heat-dissipating cylinder 24 is connected to the inner wall of the heat dissipation shell 10. All heat-dissipating cylinders 24 located on the outer side of the main shell 1 are interconnected. Several heat dissipation fins 240 extending out of the heat dissipation shell 10 are evenly connected to the heat-dissipating cylinder 24. The heat dissipation fins 240 are preferably made of materials with excellent thermal conductivity (such as copper or aluminum). In use, water vapor rises along the connecting pipes 23 into the connected heat-dissipating cylinder 24. The temperature and heat of the water vapor are transferred to the heat-dissipating cylinder 24 and the connected heat dissipation fins 240. Since the heat dissipation fins 240 on the heat-dissipating cylinder 24 extend out of the heat dissipation shell 10 and are connected to the outside, the temperature of the outside environment drives the heat dissipation fins 240 and the heat dissipating cylinder 24 to release temperature and heat rapidly. The water vapor in the heat-dissipating cylinder 24 condenses back into liquid due to the release of heat, and then falls back into the heat-conducting plate 22 along the connecting pipes 23 under its own gravity.

[0044] As the condensed liquid water falls back along the connecting pipe 23, it comes into contact with the pipe wall and further absorbs the high heat and temperature conducted on the pipe wall, thereby reducing the temperature and heat of the connecting pipe 23 and the several heat-conducting plates 21 connected to it, thus achieving secondary heat conduction and heat dissipation for the connecting pipe 23 and the heat-conducting plates 21.

[0045] Furthermore, as the liquid water falls back along the connecting pipe 23, the water vapor formed in the heat-conducting plate 22 also rises synchronously along the connecting pipe 23. During the process of the liquid water returning to the hot end, the liquid water absorbs heat from the heat pipe wall and the surrounding environment, helping to reduce the temperature of the connecting pipe 23 wall and the water vapor. This process helps to maintain the temperature gradient in the connecting pipe 23, thereby continuously transferring heat to increase the heat conduction and heat dissipation efficiency of the car battery.

[0046] Reference Figures 2 to 5As shown, several heat dissipation fins 240 located on the same heat dissipation cylinder 24 are spaced apart from each other. A guide groove 241 corresponding to the heat dissipation cylinder 24 is formed on the heat dissipation shell 10. The guide groove 241 allows airflow to pass through and forms an air duct to dissipate heat from the heat dissipation fins 240. In use, natural airflow is directed towards the heat dissipation fins 240 along the guide groove 241. The airflow is guided and concentrated by the guide groove 241 and blown towards the heat dissipation fins 240. The presence of several heat dissipation fins 240 increases the contact area between the heat dissipation cylinder 24 and the air, which helps to improve the heat dissipation efficiency of the heat dissipation fins 240 and the heat dissipation cylinder 24. This accelerates the condensation of water vapor inside the heat dissipation cylinder 24, thereby improving the heat dissipation efficiency of the car battery.

[0047] Reference Figures 2 to 5 As shown, multiple guide grooves 241 are provided, and each guide groove 241 is set one-to-one with the heat dissipation cylinder 24. The two ends of the guide groove 241 are set with slopes to guide the airflow, thereby increasing the contact area between the heat sink 240 and the airflow. At the same time, the airflow is guided by the guide groove 241 so that the airflow can be more easily gathered and blown towards the corresponding heat sink 240, which helps to improve the heat dissipation efficiency of the heat sink 240 and the heat dissipation cylinder 24.

[0048] Reference Figures 2 to 5 As shown, a plurality of clamping plates 25 for clamping the cover plate 11 are connected to the heat sink 10. The clamping plates 25 are respectively clamped on the outer edge of the cover plate 11. The clamping plates 25 are fixed to the heat sink 10 by fastening bolts. The fastening bolts are rotatably connected to the clamping plates 25 and are threaded into the heat sink 10 to fasten the clamping plates 25, thereby clamping the cover plate 11.

[0049] To improve the sealing performance of the cover plate 11 after covering the main housing 1, and to prevent external moisture from entering the main housing 1 and causing corrosion to the car battery, therefore, referring to Figure 6 As shown, a bent sealing gasket 26 is also connected to the heat dissipation shell 10. The cover plate 11 is located between the pressure plate 25 and the sealing gasket 26. The sealing gasket 26 is preferably made of a material with a certain elastic deformation capacity and good thermal aging performance. In use, the upper and lower end faces of the cover plate 11 are respectively attached between the pressure plate 25 and the sealing gasket 26. Then, by rotating the fastening bolt, the connected pressure plate 25 is moved downward. The downward movement of the pressure plate 25 presses the cover plate 11 downward as a whole, thereby causing all the sealing gaskets 26 located on the lower side of the cover plate 11 to undergo elastic deformation. The sealing gaskets 26, due to being compressed, undergo elastic deformation and have an upward elastic restoring force to drive the cover plate 11 upward. This results in a close fit between the pressure plate 25 and the cover plate 11, as well as between the cover plate 11 and the sealing gasket 26, achieving the effect of sealing the car battery installed in the main housing 1. This prevents external moisture from entering the main housing 1, causing corrosion to the car battery and affecting its service life.

[0050] Furthermore, referring to Figures 6 to 8 As shown, a sliding cavity 27 is formed in the hollow upper part of the main housing 1. A sliding push rod 270 corresponding to the sealing gasket 26 is slidably inserted into the sliding cavity 27. One end of the sliding push rod 270 extending out of the sliding cavity 27 is connected to a driven push plate 271 for abutting against the sealing gasket 26. The driven push plate 271 includes a sliding sleeve 2710 that is hollow inside and connected to the sliding push rod 270. A bent guide plate 2711 is slidably inserted into the sliding sleeve 2710. The vertical section of the bent guide plate 2711 is close to One side of the sealing gasket 26 is set as a slope. A limiting strip 2712 is symmetrically connected to the horizontal section of the bent guide plate 2711 and is slidably inserted into the sliding sleeve 2710. In the initial state, the slope of the vertical section of the bent guide plate 2711 abuts against the sealing gasket 26, and the sliding sleeve 2710 does not contact the sealing gasket 26. There is a gap between the limiting strip 2712 and the inner wall of the sliding sleeve 2710 to allow the connected bent guide plate 2711 to slide a distance away from the cover plate 11.

[0051] During use, the operation of the car battery generates heat. A portion of this heat is conducted through the main housing 1 to the sliding cavity 27, heating the gas molecules within. This raises the temperature of the air inside the sliding cavity 27, causing the internal air pressure to rise. Consequently, the sliding push rod 270 and driven push plate 271, inserted within the sliding cavity 27, tend to slide upwards as the gas temperature rises. The upward movement of the sliding push rod 270 causes the connected sliding sleeve 2710, bending guide plate 2711, and limiting strip 2712 to move upwards, and the bending guide plate 2711... 1. The upward movement pushes the sealing gasket 26, which is in contact with its inclined surface, to deform along its inclined surface. After the limiting strip 2712 connected to the bending guide plate 2711 comes into contact with the inner wall of the sliding sleeve 2710, the bending guide plate 2711 is limited and no longer slides away from the cover plate 11. At the same time, as the sliding push rod 270 continues to move upward, the outer side of the sliding sleeve 2710 comes into contact with the lower side of the sealing gasket 26. At this time, the bending guide plate 2711 and the sliding sleeve 2710 further compress the sealing gasket 26 by the inclined surface of the bending guide plate 2711 and the contact limiting of the sealing gasket 26.

[0052] Because the fastening bolts limit the pressure of the clamping plate 25 and the cover plate 11, the sealing gasket 26 is prevented from moving upwards. This causes the sealing gasket 26 to be further squeezed and pressed against the cover plate 11. When the car battery generates a lot of heat during use, the sealing gasket 26 further seals the space between the main housing 1 and the cover plate 11, preventing moisture from the outside at a lower temperature from entering the main housing 1 and condensing into water droplets due to the temperature difference between the inside and outside of the battery box, which would then drip onto the car battery and cause corrosion.

[0053] The main housing 1 and the heat dissipation shell 10 are composite materials combining metal and plastic. Using a composite material of metal and plastic as the main structure of the battery box housing leverages the advantages of each to achieve a combination of high performance and durability. The metal parts not only enhance the strength of the housing but also provide excellent heat dissipation; the plastic parts offer excellent corrosion resistance. This composite design ensures rapid heat dissipation from the battery while protecting it from external environmental corrosion, thus extending battery life and ensuring safe vehicle operation.

[0054] During operation: First, install the car battery inside the main housing 1, then cover and seal the main housing 1 with the cover plate 11. At the same time, seal the main housing 1 after installing the car battery by pressing the cover plate 11 and the sealing gasket 26 to prevent the entry of external moisture.

[0055] Step 2: When the car battery generates heat during operation, the heat generated by the car battery is transferred to the heat dissipation cavity 20 through the heat conduction plate 21 and the heat conduction plate 22 so that the heat can be dissipated, thus completing the initial heat conduction and heat dissipation effect of the car battery.

[0056] Step 3: After the car battery has been operating for a period of time, the accumulated heat causes the medium in the heat conduction plate 22 to be heated to the boiling point, and then the phase changes to a vapor state. During the phase change process, a large amount of heat is absorbed to achieve the effect of rapid heat conduction and heat dissipation by absorbing the heat generated by the car battery.

[0057] Step 4: During the operation of the car battery, the heat generated causes the air in the sliding cavity 27 on the main housing 1 to be heated and the air pressure to rise. The rising air pressure drives the sliding push rod 270 in the sliding cavity 27 to move upward, so as to further press the mating sealing gasket 26, thereby increasing the sealing effect of the sealing gasket 26 and preventing the moisture at a lower temperature from entering the main housing 1 and causing corrosion to the car battery.
