Description

Technical Field

[0001] The present invention relates to the technical field of battery heat dissipation, and in particular to a radiator for an automobile power battery. Background Art

[0002] Automotive power batteries are the core energy storage components of electric vehicles. They are typically based on lithium-ion batteries (such as ternary lithium batteries and lithium iron phosphate batteries). They feature high energy density, long cycle life, and stable charge and discharge performance, providing continuous power output for the vehicle. Their operating principle is to convert electrical energy into chemical energy through the intercalation and deintercalation of lithium ions between the positive and negative electrodes. A battery management system (BMS) is also required to monitor voltage, temperature, and other conditions to ensure safe and efficient operation. With technological advancements, power batteries are evolving toward higher energy density, faster charging speeds, and lower costs, becoming a key foundation for the development of the new energy vehicle industry.

[0003] In some vehicle models, the radiator coolant circulation in low-temperature environments can create an energy conflict with the battery preheating system. Specifically, when the vehicle is started in a low-temperature environment, the battery needs to be preheated to reach the optimal operating temperature. However, the coolant circulating in the radiator will dissipate some of the heat generated during the preheating process, thereby affecting the battery preheating efficiency and increasing energy consumption.

The outer surface of the bonding plate close to the liquid pump is fixedly connected to a water pipe, and the top of the bonding plate is fixedly connected to a top pipe, and the top of the top pipe is fixedly connected to a storage layer. The top of the storage layer is symmetrically provided with a power board, and the outer surface of the power board is fixedly connected to a magnetic column, which is made of neodymium iron boron permanent magnet material. The outer surface of the magnetic column is wound with a coil, and the coil is wound with enameled wire;

[0008] The liquid cooling unit also includes a guide column arranged in the bonding plate, the outer surface of the guide column is slidably connected to the lifting plate, and the top of the lifting plate is fixedly connected to a magnetic block that attracts the magnetic column, and the magnetic poles of the magnetic block are opposite to the magnetic poles of the magnetic column.

[0009] Preferably, battery packs are evenly arranged inside the battery housing, and the battery packs adopt a modular design to facilitate installation and maintenance. A conductive component is arranged on the top of the battery pack, and the conductive component is composed of multiple strands of copper wires with an insulating material wrapped on the surface. The battery pack conducts electricity through the conductive component.

[0010] Preferably, the outer surface of the bonding plate contacts the outer surface of the battery pack, and thermal grease is applied between the two to fill the tiny gap to further improve the heat conduction efficiency. The bottom of the guide column is fixedly connected to the inner wall of the bonding plate.

[0011] Preferably, one end of the water pipe away from the laminating plate is fixedly connected to the outer surface of the liquid pump, and both ends of the coil are fixedly connected to the outer surface of the power board;

[0012] After the power supply is energized to the coil, the magnetic force of the magnetic column increases and attracts the lifting plate connected to the magnetic block to move.

[0013] Preferably, the guide column will limit the movement of the lifting plate, ensuring that the lifting plate can only move in the vertical direction to avoid deviation. The outer surface of the lifting plate is in close contact with the inner wall of the bonding plate, and a wear-resistant seal is provided between the two to prevent coolant leakage.

[0014] Preferably, when the air cooling unit is working, the air extractor draws air from the top of the battery housing to form a pressure difference.

[0015] Preferably, the air cooling unit includes side panels symmetrically arranged on both sides of the battery housing, the bottom of the side panel is fixedly connected to an air inlet duct, one end of the air inlet duct is provided with an isolation plate, the isolation plate is at the front end of the car, the outer surface of the side panel is fixedly connected to support plate 2, the inner wall of support plate 2 is fixedly connected to a servo motor, the output end of the servo motor is fixedly connected to gear 1, a track is engaged on the gear 1, and wind power mechanisms are evenly arranged in the side panels.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The present invention sets a liquid cooling unit, and a pump will pump the coolant in the storage box into the bonding plate. The coolant will absorb the heat energy generated by the battery pack. However, in the radiator of some models under low temperature environment, the coolant circulation will generate energy offset with the battery preheating system. Therefore, when the vehicle is started at low temperature, the power supply will energize the coil, thereby strengthening the magnetic force of the magnetic column and attracting the magnetic block, so that the lifting plate moves upward and drives the coolant in the liquid cooling unit to move upward and finally enter the storage layer through the top pipe, so that the coolant does not cool the battery pack when the vehicle is started.

[0021] 2. The present invention provides an air cooling unit. When the car is driving, the air inlet duct and the isolation plate are located at the front end of the car, so the driving wind will enter the air inlet duct. Then the servo motor will drive gear 1 to rotate and drive the wind mechanism through the transmission of the crawler track to transmit the wind into the battery housing. At the same time, the air pump will draw air from the top of the battery housing to form a pressure difference, thereby increasing the circulation effect of the wind in the battery housing and increasing the gas conversion efficiency.

[0032] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0033] Example 1: Use Figures 1-9 An automotive power battery radiator according to one embodiment of the present invention is described below.

[0034] like Figure 1-Figure 3 As shown, an automotive power battery radiator of the present invention includes a battery housing 1, vents 2 are provided on both sides of the battery housing 1, an air pump 3 is provided on the top of the battery housing 1, a support plate 11 is further provided on the outer surface of the battery housing 1, a storage box 8 is fixedly connected to the outer surface of the support plate 11, a liquid pump 9 is provided on the top of the storage box 8, and an interface 10 is also provided on the battery housing 1, and further includes:

[0035] A liquid cooling unit 6 is provided on the battery pack 4 and an air cooling unit 7 is provided on both sides of the battery housing 1;

[0036] The liquid cooling unit 6 is replaced by the liquid pump 9, and the air cooling unit 7 is circulated by the gas pump 3;

[0037] When the battery pack 4 is working to transmit electricity, heat energy is generated. When the temperature is high, the liquid cooling unit 6 and the air cooling unit 7 will cool the battery pack 4 at the same time. At the same time, when the vehicle is started and preheated, no wind will be generated in the air cooling unit 7, and the liquid cooling unit 6 will also stop cooling the battery pack 4.

[0038] like Figure 3-Figure 6 As shown, the liquid cooling unit 6 includes a bonding plate 61, which is made of aluminum alloy with high thermal conductivity and can quickly conduct heat energy. The bonding plates 61 are evenly arranged in the shell, and a series pipe 62 is arranged between the bonding plates 61. The outer surface of the bonding plate 61 close to the liquid pump 9 is fixedly connected to a water pipe 63, and the top of the bonding plate 61 is fixedly connected to a top pipe 611. The top of the top pipe 611 is fixedly connected to a storage layer 64. A power supply board 65 is symmetrically arranged on the top of the storage layer 64. The outer surface of the power supply board 65 is fixedly connected to a magnetic column 66. The magnetic column 66 is made of neodymium iron boron permanent magnet material. The outer surface of the magnetic column 66 is wound with a coil 67, and the coil 67 is wound with enameled wire.

[0039] When the temperature of the battery pack 4 is high, the pumping machine 9 will pump the coolant in the storage box 8 into the bonding plate 61 , and the coolant will absorb the heat energy generated by the battery pack 4 .

[0040] The liquid cooling unit 6 also includes a guide column 68 arranged in the bonding plate 61. The outer surface of the guide column 68 is slidably connected to the lifting plate 69. The top of the lifting plate 69 is fixedly connected to a magnetic block 610 that attracts the magnetic column 66. The magnetic poles of the magnetic block 610 are opposite to the magnetic poles of the magnetic column 66.

[0041] In low-temperature environments, the coolant circulation of the radiator of some models will produce energy offset with the battery preheating system. Therefore, when the vehicle is started at low temperature, the power supply will energize the coil 67, thereby strengthening the magnetic force of the magnetic column 66 and attracting the magnetic block 610, so that the lifting plate 69 moves upward, driving the coolant into the storage layer 64 through the top pipe 611 and finally into the storage layer 64 through the top pipe 611, so that the coolant does not cool the battery pack 4 during vehicle startup.

[0042] Battery packs 4 are evenly arranged inside the battery housing 1. The battery packs 4 adopt a modular design to facilitate installation and maintenance. A conductive component 5 is arranged on the top of the battery pack 4. The conductive component 5 is composed of multiple strands of copper wires and the surface is wrapped with insulating material. The battery pack 4 conducts electricity through the conductive component 5.

[0043] The outer surface of the bonding plate 61 contacts the outer surface of the battery pack 4 , and thermal grease is applied between the two to fill the tiny gap and further improve the heat conduction efficiency. The bottom of the guide column 68 is fixedly connected to the inner wall of the bonding plate 61 .

[0044] One end of the water pipe 63 away from the laminating plate 61 is fixedly connected to the outer surface of the liquid pump 9, and both ends of the coil 67 are fixedly connected to the outer surface of the power supply board 65;

[0045] After the power supply is energized to the coil 67 , the magnetic force of the magnetic column 66 increases and attracts the lifting plate 69 connected to the magnetic block 610 to move.

[0046] The guide column 68 will limit the movement of the lifting plate 69, ensuring that the lifting plate 69 can only move in the vertical direction to avoid deviation. The outer surface of the lifting plate 69 is in close contact with the inner wall of the bonding plate 61, and a wear-resistant seal is provided between the two to prevent coolant leakage.

[0047] The specific workflow is as follows:

[0048] During operation, the pumping machine 9 will pump the coolant in the storage box 8 into the bonding plate 61, and the coolant will absorb the heat energy generated by the battery pack 4. When preheating the car, the power supply will energize the coil 67, thereby strengthening the magnetic force of the magnetic column 66 and attracting the magnetic block 610, so that the lifting plate 69 moves upward, driving the coolant through the top pipe 611 into the storage layer 64 and finally into the storage layer 64 through the top pipe 611, so that the coolant does not cool the battery pack 4 when the vehicle is started.

[0049] Example 2: Use Figures 1-9 An automotive power battery radiator according to one embodiment of the present invention is described below.

[0050] like Figure 7-Figure 8 As shown, a car power battery radiator of the present invention is based on the first embodiment. When the air cooling unit 7 is working, the air extractor 3 will extract the air on the top of the battery housing 1 to form a pressure difference.

[0051] The air cooling unit 7 includes side panels 71 symmetrically arranged on both sides of the battery housing 1. The bottom of the side panel 71 is fixedly connected to an air inlet duct 72. An isolation plate 73 is provided at one end of the air inlet duct 72. The isolation plate 73 is located at the front end of the car. The outer surface of the side panel 71 is fixedly connected to a support plate 2 74. The inner wall of the support plate 2 74 is fixedly connected to a servo motor 75. The output end of the servo motor 75 is fixedly connected to a gear 1 76. A track 77 is engaged with the gear 1 76. Wind power mechanisms 78 are evenly arranged in the side panels 71.

[0052] When the car is driving, since the air inlet duct 72 and the isolation plate 73 are located at the front end of the car, the wind force will enter the air inlet duct 72, and then the servo motor 75 will drive the gear 1 76 to rotate and drive the wind mechanism 78 through the transmission of the track 77 to transmit the wind force into the battery housing 1.

[0053] The outer surface of the side panel 71 is fixedly connected to the outer surface of the battery housing 1 by bolt connection, which is convenient for disassembly and installation. The inner side of the side panel 71 faces the vent hole 2 to ensure that air can smoothly pass through the vent hole 2 into the interior of the battery housing 1.

[0054] like Figure 9 As shown, the wind mechanism 78 includes a rotating column 781, the outer surface of which is fixedly connected to a gear 2 782, and the end of the gear 2 782 away from the rotating column 781 is fixedly connected to a support rod 783, and the outer surface of the support rod 783 is evenly provided with propeller fans 784.

[0055] As the track 77 is driven, the gear 2 782 will be driven to rotate, thereby driving the support rod 783 and the propeller fan 784 to rotate, so that the cold air entering the air inlet duct 72 enters the battery housing 1. At the same time, the exhaust fan 3 will extract the air at the top of the battery housing 1, forming a pressure difference, increasing the circulation effect of the wind in the battery housing 1, and increasing the gas conversion efficiency.

[0056] One side of the rotating column 781 is rotatably connected to the inner wall of the side plate 71 , and a bearing is provided at the rotatably connected portion. The second gear 782 is meshed with the crawler belt 77 .

[0057] The specific workflow is as follows:

[0058] When the air cooling unit 7 is working, as the car moves, cold air will enter the air inlet duct 72, the isolation plate 73 will block dust and impurities in the air, the servo motor 75 will drive gear 1 76 to rotate and drive gear 2 782 to rotate through the track 77, thereby driving the support rod 783 and the propeller fan 784 to rotate, so that the cold air entering the air inlet duct 72 enters the battery housing 1, and at the same time the exhaust fan 3 will extract the air at the top of the battery housing 1, forming a pressure difference, increasing the circulation effect of the wind in the battery housing 1, and increasing the gas conversion efficiency.

[0059] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
