Description

Technical Field

[0001] The invention relates to the field of automobile batteries, and in particular to a corrosion-resistant and heat-dissipating automobile battery box shell of an automobile battery. Background Art

[0002] With the rapid development of the new energy vehicle industry, the performance requirements for automotive battery boxes are getting higher and higher. The battery box must not only have good mechanical strength and corrosion resistance, but also have efficient heat dissipation performance to ensure stable operation of the battery and extend its service life.

[0003] However, there are usually some problems in the daily use of ordinary automobile battery boxes. With the development of science and technology, technicians in related fields have also made a lot of optimizations on the battery boxes of automobile batteries. In order to make a more accurate comparison, a Chinese patent with publication number CN112234299A discloses a battery box shell for new energy electric vehicles, including a main shell, a support seat, a box cover, a pushing mechanism, a heat dissipation and cooling mechanism, and a locking mechanism; when in use, the battery is installed in the main shell, the box cover clamps the top of the main shell, and then the rotating shaft is driven to rotate by the card frame to clamp the top side of the box cover, and the fixing bolts are rotated to fix the card frame and the box cover, thereby improving the sealing effect of the box cover. At the same time, when working, the heat generated by the battery is discharged through the heat dissipation fins, and the semiconductor refrigeration sheet is cooled at the same time, and the heat is discharged through the cold plate. The discharged heat is cooled by the water in the cavity, thereby improving the heat cooling effect, thereby facilitating the auxiliary heat dissipation of the battery placed in the shell, improving the heat dissipation effect, and meeting the use requirements.

[0004] However, the above-mentioned car battery box still has some shortcomings in actual use:

[0005] 1. The above-mentioned battery box is cooled by a semiconductor refrigeration sheet, and the heat generated by the battery in the battery box during operation is then conducted out by a cooling sheet. At the same time, water is poured into the cavity in the battery box to cool down the battery in the cavity, thereby facilitating auxiliary heat dissipation for the battery placed in the shell. However, when it is used, it is necessary to pre-inject more water into the cavity and store it in the box. After injecting more water into the battery box, the overall weight of the battery box will increase significantly, which will cause the battery in the battery box to require more power consumption to complete the corresponding drive during actual operation. More power consumption of the battery means that more heat will be generated, thereby slowing down the efficiency of heat dissipation of the battery.

[0006] 2. The above device is used to dissipate heat from the batteries in the battery box by means of semiconductor cooling plates and cooling conductors arranged at the bottom of the box body. However, in actual use, the above device does not make the cooling conductors and semiconductor cooling plates directly fit the outer side surfaces of the batteries. Instead, the device dissipates heat from the water in the cavity and then guides and converts the heat generated by the batteries by indirect heat conduction. In actual applications, it is difficult to quickly guide and dissipate the heat generated by the batteries in a short time, and the efficiency is low.

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

[0013] Preferably, the heat sinks on the same heat sink are spaced apart from each other, and a guide groove corresponding to the heat sink is provided on the heat sink shell, the guide groove is used for airflow to pass through and form an air duct to dissipate heat for the heat sink.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1 To Attachment Figure 8 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0035] The embodiment of the present application discloses a corrosion-resistant and heat-dissipating automobile battery box shell for an automobile battery, and it is explained that the battery box shell is mainly used in the process of installing and using the automobile battery, and technically realizes the closed installation of the automobile battery to prevent external water vapor from entering the battery box and causing corrosion of the automobile battery; especially in the normal use of the automobile battery after installation, the heat generated by the automobile battery is effectively evacuated through the contact between the heat conductive plate and a plurality of heat conductive sheets and the automobile battery, thereby achieving the effect of heat dissipation of the automobile battery; further, the battery box shell also quickly cools down the steam in the connecting pipe and the heat conductive plate through the arranged connecting pipe, heat release tube and heat sink, thereby achieving the effect of quickly cooling the automobile battery.

[0036] Reference Figure 1 and Figure 2 As shown, a corrosion-resistant and heat-dissipating automobile battery box shell of an automobile battery comprises a main shell 1, a heat dissipation shell 10, a cover plate 11 and a radiator 2. The main shell 1 is arranged in a quadrilateral structure and is provided with an opening. The heat dissipation shell 10 is sleeved on the outside of the main shell 1. The heat dissipation shell 10 is connected to a cover plate 11 for covering and sealing the main shell 1. A radiator 2 for dissipating heat from the battery installed in the main shell 1 is installed between the main shell 1 and the heat dissipation shell 10. The main shell 1, the heat dissipation shell 10 and the cover plate 11 cooperate with each other to form a complete battery box for the installation of automobile batteries. When in use, the automobile battery is installed in the main shell 1, and the main shell 1 is covered by the cover plate 11 to complete the sealing and installation of the automobile battery. Then, when the automobile battery is in operation, the heat generated by the automobile battery is guided and converted by the heat dissipation shell 10, thereby achieving the effect of dissipating heat from the installed automobile battery.

[0037] Reference Figures 2 to 5 As shown, a radiator 2 is used to dissipate heat for a battery installed in a main shell 1; specifically, the radiator 2 includes a heat dissipation cavity 20, a heat conductive sheet 21 and a heat conductive plate 22. A heat dissipation cavity 20 is formed in the hollow interior between the main shell 1 and the heat dissipation shell 10. A plurality of heat conductive sheets 21 inserted on the main shell 1 are evenly arranged in the heat dissipation cavity 20. The plurality of heat conductive sheets 21 are evenly distributed on the outer side surface of the main shell 1 and one end is inserted into the main shell 1 to resist the outer side wall of the battery. A heat conductive plate 22 for supporting the battery and fitting with the bottom of the battery is connected to the bottom of the main shell 1. The interior of the heat conductive plate 22 is hollow for storing a medium. The lower side of the heat conductive plate 22 is located in the heat dissipation cavity 20. It should be noted that the heat conductive plate 22 and the heat conductive sheet 21 are preferably made of materials with excellent thermal conductivity (such as copper or aluminum, etc.), and the medium is preferably a fluid with high thermal properties and a suitable boiling point. As an optional implementation, water is used as the working medium in the heat conductive plate 22 in this embodiment.

[0038] When the car battery is in use, its positive and negative electrode materials undergo chemical reactions to release electrons and ions. This process is usually accompanied by the release of energy, part of which is dissipated in the form of heat energy, causing the temperature at the battery to rise, making the heat at the car battery in the battery box higher than other locations. Since the heat conducting plate 22 and a plurality of heat conducting sheets 21 are in contact with the car battery, the temperature of the heat conducting plate 22 and the heat conducting sheets 21 on the side in contact with the car battery is higher than the side located in 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 is transferred to the low heat in the heat dissipation cavity 20, so that the high heat of the car battery in the main shell 1 gradually decreases, while the low heat in the heat dissipation cavity 20 gradually increases, so as to achieve the effect of cooling the car battery until the heat in the main shell 1 and the heat dissipation cavity 20 is in a balanced state.

[0039] In the process of conducting the high heat of the automobile battery through the heat conducting plate 22, a part of the high heat is transferred to the water in the heat conducting plate 22 after passing through the heat conducting plate 22, so that the water in the heat conducting plate 22 is heated. The process of heating the water in the heat conducting plate 22 completes the absorption and conversion of the heat conducted from the automobile battery, thereby achieving the effect of promoting the heat dissipation efficiency of the automobile battery.

[0040] Furthermore, as the car battery continues to operate, the heat and temperature generated by the battery also continue to increase and rise. After a period of transfer, the heat and temperature between the heat dissipation cavity 20 and the main housing 1 gradually become relatively balanced, and the efficiency and effect of heat dissipation for the car battery gradually decrease and weaken. Based on this, refer to Figures 2 to 5 As shown, a connecting pipe 23 is commonly penetrated on a plurality of heat conducting sheets 21 located on the same side of the main housing 1, and the connecting pipe 23 is connected to the heat conducting plate 22, and the connecting pipe 23 is located in the heat dissipation cavity 20. When in use, the heat generated by the automobile battery is transferred to the heat conducting plate 22 and the water in the heat conducting plate 22, so that the water in the heat conducting plate 22 is heated to the boiling point, and then the water is transformed into steam by phase change. In the process of forming steam, the water absorbs the heat at the heat conducting plate 22, so as to achieve the effect of heat dissipation at the heat conducting plate 22 and the automobile battery.

[0041] After the water in the heat conducting plate 22 is converted into water vapor during the phase change process, the water vapor rises along the connecting tube 23 connected to the heat conducting plate 22 because the density of the water vapor is usually lower than the density of the air. In the process of rising, the water vapor synchronously absorbs and converts the heat of the heat conducting sheet 21 connected to the connecting tube 23, thereby achieving the effect of dissipating heat to the side wall of the battery.

[0042] Reference Figures 2 to 5As shown, a plurality of connecting tubes 23 are evenly penetrated on any heat conducting sheet 21, and a plurality of connecting tubes 23 on the same side are simultaneously penetrated on a plurality of heat conducting sheets 21 on the same side. When in use, water vapor is guided through a plurality of connecting tubes 23 connected to the heat conducting plate 22, and in the process of water vapor rising along the connecting tubes 23, heat is also conducted to the heat conducting sheet 21 connected to the connecting tubes 23, thereby accelerating the heat dissipation effect of the heat conducting plate 22 and the heat conducting sheet 21.

[0043] Furthermore, in order to recycle the water converted into water vapor to save costs, refer to Figures 2 to 5 As shown, the ends of several connecting tubes 23 on the same side away from the heat conducting plate 22 are connected to a heat releasing tube 24, which is connected to the inner wall of the heat dissipation shell 10, and all the heat releasing tubes 24 located outside the main shell 1 are connected to each other. The heat releasing tubes 24 are evenly connected to several heat sinks 240 that pass through the heat dissipation shell 10, and the heat sinks 240 are preferably made of materials with excellent thermal conductivity (such as copper or aluminum, etc.). When in use, after the water vapor rises along the connecting tubes 23 to the connected heat releasing tubes 24, the temperature and heat of the water vapor are transferred to the heat releasing tubes 24 and the connected heat sinks 240. Since the heat sinks 240 on the heat releasing tubes 24 pass through the heat dissipation shell 10 and are connected to the outside world, the temperature and heat in the heat sinks 240 and the heat releasing tubes 24 are driven to be quickly released by the temperature of the outside world, and the water vapor in the heat releasing tubes 24 condenses into liquid again due to the release of heat, and then falls back along the connecting tubes 23 under the influence of its own gravity into the heat conducting plate 22.

[0044] In the process of the condensed liquid water falling back along the connecting tube 23, after the liquid water contacts the tube wall of the connecting tube 23, it further absorbs the high heat and temperature conducted on the tube wall, so that the temperature and heat of the connecting tube 23 and the plurality of heat conducting plates 21 connected to the connecting tube 23 are reduced, thereby achieving a secondary heat conduction and heat dissipation effect on the connecting tube 23 and the heat conducting plates 21.

[0045] In addition, as the liquid water falls back along the connecting tube 23, the water vapor formed in the heat conducting plate 22 also rises synchronously along the connecting tube 23. As the liquid water returns to the hot end, the liquid water absorbs the heat from the heat pipe wall and the surrounding environment, helping to lower the temperature of the connecting tube 23 wall and the water vapor. This process helps to maintain the temperature gradient in the connecting tube 23, thereby continuously transferring heat to increase the thermal conductivity and heat dissipation efficiency of the vehicle battery.

[0046] Reference Figures 2 to 5As shown, a plurality of heat sinks 240 located on the same heat release tube 24 are arranged at intervals, and a guide groove 241 corresponding to the heat release tube 24 is provided on the heat release shell 10, and the guide groove 241 is provided for air flow to pass through and form an air duct to dissipate heat from the heat sink 240. When in use, by allowing natural air flow to blow toward the heat sink 240 along the guide groove 241, the air flow is guided and gathered through the guide groove 241 to blow toward the heat sink 240, and the contact area between the heat release tube 24 and the air is increased through a plurality of heat sinks 240, which helps to improve the heat release efficiency of the heat sink 240 and the heat release tube 24, thereby accelerating the condensation of water vapor in the heat release tube 24, and further improving the heat release efficiency of the vehicle battery.

[0047] Reference Figures 2 to 5 As shown, a plurality of guide grooves 241 are provided, and the plurality of guide grooves 241 are arranged corresponding to the heat release tube 24 one by one. Both ends of the guide grooves 241 are arranged in a sloped surface to guide the airflow, thereby achieving the effect of increasing the contact area between the heat sink 240 and the airflow. At the same time, the airflow is guided by the guide grooves 241 so that the airflow can be more easily gathered and blown toward the corresponding heat sink 240, which helps to improve the heat release efficiency of the heat sink 240 and the heat release tube 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 dissipation shell 10, and the clamping plates 25 are respectively clamped on the outer edges of the cover plate 11, and the clamping plates 25 are fixed to the heat dissipation shell 10 by fastening bolts, wherein the fastening bolts are rotatably connected to the connected clamping plates 25 and are threadedly inserted into the heat dissipation shell 10 to fasten the connected clamping plates 25, so that the clamping plates 25 clamp the cover plate 11.

[0049] In order to improve the sealing performance of the cover plate 11 after covering the main housing 1, so as to prevent the external water vapor from entering the main housing 1 and causing corrosion to the car battery, Figure 6 As shown, the heat dissipation shell 10 is also connected with a sealing gasket 26 with a bent structure, and the cover plate 11 is located between the pressing plate 25 and the sealing gasket 26. The sealing gasket 26 is preferably made of a material with a certain elastic deformation ability and good thermal aging performance. When in use, the upper and lower end surfaces of the cover plate 11 are respectively fitted between the pressing plate 25 and the sealing gasket 26, and then the fastening bolts are rotated to move the connected pressing plate 25 downward, and the pressing plate 25 moves downward to press the cover plate 11 as a whole, so as to drive all the sealing gaskets 26 located on the lower side of the cover plate 11 to produce elastic deformation, and the sealing gasket 26 is elastically deformed due to being pressed, and has an elastic reset force that is always upward to drive the cover plate 11 to move upward, so that the pressing plate 25 and the cover plate 11 and the cover plate 11 and the sealing gasket 26 are closely fitted, so as to achieve the effect of sealing the car battery installed in the main shell 1, so as to prevent the external water vapor from entering the main shell 1, causing corrosion to the car battery and affecting the service life of the car battery.

[0050] Further, refer to Figures 6 to 8 As shown, a sliding cavity 27 is formed in the main housing 1 in a hollow shape, and a sliding push rod 270 corresponding to the sealing gasket 26 is slidably inserted in the sliding cavity 27, and one end of the sliding push rod 270 passing through the sliding cavity 27 is connected to a driven push plate 271 for contacting the sealing gasket 26, wherein the driven push plate 271 includes a sliding sleeve 2710 which is hollow and connected to the sliding push rod 270, and a bending guide plate 2711 is slidably inserted in the sliding sleeve 2710, and the vertical section of the bending guide plate 2711 is close to One side of the sealing gasket 26 is set to a slope, and the horizontal section of the bending guide plate 2711 is symmetrically connected to a limit clip 2712 that is slidably inserted in the sliding sleeve 2710. In the initial state, the slope of the vertical section of the bending guide plate 2711 is in contact with the sealing gasket 26, and the sliding sleeve 2710 is not in contact with the sealing gasket 26. There is a distance between the limit clip 2712 and the inner side wall of the sliding sleeve 2710 to allow the connected bending guide plate 2711 to slide a distance away from the cover plate 11.

[0051] When in use, the operation of the car battery generates heat, and part of the heat generated by the car battery is conducted to the sliding chamber 27 through the main shell 1, heating the gas molecules in the sliding chamber 27, so that the air in the sliding chamber 27 is heated up. After the sliding chamber 27 is heated up, the internal air pressure thereof also rises with the temperature, so that the sliding push rod 270 and the driven push plate 271 inserted in the sliding chamber 27 have a tendency to slide upward when the gas in the sliding chamber 27 is heated up. The upward movement of the sliding push rod 270 drives the connected sliding sleeve 2710, the bending guide plate 2711 and the limit card strip 2712 to move upward, and the bending guide plate 271 The sealing gasket 26 that contacts with its inclined surface is pushed upward to deform along its inclined surface. After the limiting clamping strip 2712 connected to the bending guide plate 2711 contacts 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 surface of the sliding sleeve 2710 contacts the lower side of the sealing gasket 26. At this time, the bending guide plate 2711 and the sliding sleeve 2710 further squeeze the sealing gasket 26 through the inclined surface of the bending guide plate 2711 and the contact and limitation of the sliding sleeve 2710 on the sealing gasket 26.

[0052] Since the fastening bolts limit the clamping plate 25 and the cover plate 11, the sealing gasket 26 is limited and cannot continue to move upward, so that the sealing gasket 26 is further squeezed and pressed against the cover plate 11. When the automobile battery generates more heat during use, the sealing gasket 26 further seals the main shell 1 and the cover plate 11 to prevent the water vapor with lower temperature from entering the main shell 1. Due to the temperature difference between the inside and outside of the battery box, it condenses into water droplets and drips on the automobile battery, causing corrosion to the automobile battery.

[0053] The main housing 1 and the heat dissipation shell 10 are composite materials of metal and plastic. The composite materials of metal and plastic are used as the main structure of the battery box housing, taking advantage of their respective advantages to achieve a combination of high performance and durability. The metal part can not only enhance the strength of the housing, but also has good heat dissipation performance; the plastic part provides excellent corrosion resistance. This composite design material ensures that the battery can dissipate heat quickly while protecting the battery from corrosion from the external environment, thereby extending the battery life and ensuring the safe operation of the vehicle.

[0054] During operation: the first step is to install the car battery in the main housing 1, and then cover the cover 11 to cover and seal the main housing 1. At the same time, by pressing the cover 11 and the sealing gasket 26, the main housing 1 after the car battery is installed is sealed to prevent the entry of external water vapor.

[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 conductive sheet 21 and the heat conductive plate 22 to dissipate the heat, thereby achieving the effect of preliminary heat conduction and heat dissipation of the car battery.

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

[0057] Step 4: During the operation of the automobile battery, the heat generated by the battery causes the air in the sliding cavity 27 on the main shell 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 to further tighten the contacting sealing gasket 26, thereby increasing the sealing effect of the sealing gasket 26 and preventing the water vapor with a lower temperature from entering the main shell 1 and causing corrosion to the automobile battery.
