Description

Technical Field

[0001] This utility model relates to the technical field of battery cooling devices, specifically a vehicle battery cooling device. Background Technology

[0002] Automotive battery cooling systems are used to regulate battery temperature and prevent overheating or overcooling. They are primarily used in the power battery packs of electric and hybrid vehicles. Their core purpose is to maintain the battery within its optimal operating temperature range (typically 20–40°C), thereby improving performance, extending lifespan, and ensuring safety.

[0003] Existing patent document CN112701398A discloses a shock-resistant and cooling device for a new energy vehicle battery pack, comprising a housing with a mounting bracket installed in the middle of one side; a fixing plate connected to the housing near the mounting bracket; an air outlet mechanism installed in the lower part of the housing; an air guide mechanism connected to the fixing plate; and an air supply assembly connected between the air guide mechanism and the air outlet mechanism. This invention achieves cooling of the battery pack through the air outlet mechanism, air guide mechanism, air supply assembly, and drive mechanism, and further utilizes an air intake duct to collect air for cooling during driving.

[0004] Although this device has many beneficial effects, it still has the following problems: During operation, the device relies on wind cooling, using a fan to draw air into the casing and circulate it to remove heat from the battery, achieving a cooling effect. However, under prolonged vehicle operation, the cooling effect of the wind mechanism is limited, and the internal temperature of the casing slowly rises. Over extended use, it becomes difficult to maintain a normal internal temperature, and the cooling effect gradually diminishes, resulting in poor heat dissipation efficiency. Furthermore, the device lacks external protection. If subjected to a strong impact, the casing may deform, preventing the battery from being installed or damaging batteries already installed inside, indicating poor casing protection. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the aforementioned issues, this device relies on wind power for cooling during operation. A fan draws air into the casing, circulating it to remove heat from the battery and achieve a cooling effect. However, during prolonged vehicle operation, the cooling effect of the wind system is limited, causing the internal temperature of the casing to rise slowly. Over extended use, it becomes difficult to maintain a normal temperature, leading to a gradual decrease in cooling efficiency. Furthermore, if the device is subjected to a strong impact, the casing may deform, preventing battery installation or damaging batteries already installed. This results in poor casing protection.

[0008] Therefore, the purpose of this utility model is to provide a car battery cooling device. A water tank is fixedly connected to the front of the device's casing, and a water pump is fixedly connected to the top of the water tank via a pad. The water pump draws coolant from the water tank and delivers it to the cooling copper pipes. The coolant inside the cooling copper pipes circulates due to the water pump and passes through a heat absorber head, carrying away the heat absorbed by the cooling copper pipes and the heat absorber head, and then returning it to the water tank. This cycle continues, with the coolant continuously circulating through the cooling copper pipes and the heat absorber head to absorb heat. This prevents the internal temperature of the casing from continuously rising due to the reduced cooling performance of the fan during long-term car operation, further enhancing the device's heat dissipation performance. Furthermore, during installation and transportation, the device may be accidentally dropped or impacted due to mishandling. Impacts may deform the casing, making it impossible to install the battery or damaging the battery already installed. Protective frames and inner protective rods fixedly connected to both sides of the device can withstand impacts, protecting the casing from deformation and providing good protection.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0011] A car battery cooling device includes an outer casing, a water tank fixedly connected to the back of the outer casing, an inlet on the top of the water tank, a level gauge on the front of the water tank, a pad fixedly connected to the top of the water tank, a water pump fixedly connected to the top of the pad, a heat dissipation copper pipe fixedly connected to the back of the water pump, a heat absorption head penetrating the surface of the heat dissipation copper pipe, one end of the heat dissipation copper pipe fixedly connected to the water pump, and the other end of the heat dissipation copper pipe fixedly connected to the water tank.

[0012] In a preferred embodiment of the automotive battery cooling device of this utility model, a protective frame is fixedly connected to both sides of the outer shell, and an inner protective rod is fixedly connected inside the protective frame.

[0013] In a preferred embodiment of the automotive battery cooling device of this utility model, a limiting rod is fixedly connected inside the outer shell, and heat dissipation fins are fixedly connected to the side of the limiting rod. The heat dissipation effect of the device can be enhanced by the cooperation between the heat dissipation fins and the heat dissipation holes.

[0014] In a preferred embodiment of this automotive battery cooling device, heat dissipation holes are provided on both sides of the outer casing, and an outer frame is provided on the front of the outer casing. The heat dissipation holes enhance airflow within the device, resulting in better heat dissipation.

[0015] As a preferred embodiment of the automotive battery cooling device of this utility model, the top of the outer shell is connected to a cover plate via a pivot, and a handle is fixedly connected to the front of the cover plate. The cover plate can be opened by the handle to facilitate the installation of the battery pack inside, and the cover plate also has a certain protective function.

[0016] As a preferred embodiment of the automotive battery cooling device of this utility model, the interior of the outer shell is connected to a fixing bolt by a thread, and the surface of the fixing bolt is connected to a fixing block by a thread. The side of the fixing block is fixedly connected to the outer frame. The air-cooling fan of the device can be installed on the outside of the device by the cooperation of the fixing block and the fixing bolt, which is relatively convenient for installation.

[0017] In a preferred embodiment of the automotive battery cooling device of this utility model, the outer frame has a connection port fixedly connected to its surface, a front protective frame is fixedly connected to the inside of the outer frame, the front protective frame is provided with a collar, a fan blade is fixedly connected to the surface of the collar, and a rear protective frame is fixedly connected to the inside of the outer frame.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This type of automotive battery cooling device has a water tank fixedly connected to its front. Coolant can be injected into the water tank through an inlet. When the battery inside the device needs to be used for a long time and the air cooling mechanism cannot maintain the internal temperature of the device at a suitable level, a water pump can draw coolant from the water tank and deliver it to the cooling copper pipes. At the same time, the cooling copper pipes and heat absorbers continuously absorb the heat generated by the battery pack during operation. When the coolant circulates inside the cooling copper pipes, it carries away some of the heat absorbed by the cooling copper pipes and heat absorbers and returns it to the water tank, thereby achieving the purpose of coolant circulation and maintaining a relatively suitable temperature inside the device, further enhancing the heat dissipation effect.

[0021] This type of automotive battery cooling device features a protective frame fixedly connected to both sides of the outer casing, with an inner protective rod fixedly connected inside the protective frame. This design prevents the device from slipping or being damaged by a large impact during transportation or installation. In the event of an impact, the protective frame and inner protective plate absorb the impact, protecting the outer casing from deformation that could affect the operation of the internal battery pack.

[0035] This utility model provides an overall structural schematic diagram of an embodiment of an automotive battery cooling device, including:

[0036] Please see Figures 1-6This embodiment of a car battery cooling device includes a housing 1, a water tank 17 fixedly connected to the back of the housing 1, an inlet 18 on the top of the water tank 17, a level gauge 19 on the front of the water tank 17, a pad 21 fixedly connected to the top of the water tank 17, a water pump 20 fixedly connected to the top of the pad 21, a heat dissipation copper pipe 23 fixedly connected to the back of the water pump 20, a heat absorption head 22 penetrating the surface of the heat dissipation copper pipe 23, a water pump 20 fixedly connected to one end of the heat dissipation copper pipe 23, and a water tank 17 fixedly connected to the other end of the heat dissipation copper pipe 23.

[0037] It is worth noting that, in order to prevent the outer shell 1 from deforming when the device is impacted, protective frames 15 are fixedly connected to both sides of the outer shell 1, and inner protective rods 16 are fixedly connected inside the protective frames 15.

[0038] Next, in order to cooperate with the heat dissipation hole 4 to dissipate the heat generated by the battery inside the device, specifically, a limiting rod 14 is fixedly connected inside the outer shell 1, and heat dissipation fins 5 are fixedly connected to the side of the limiting rod 14.

[0039] Meanwhile, in order to ensure airflow inside the shell, specifically, heat dissipation holes 4 are provided on both sides of the outer shell 1, and an outer frame 6 is provided on the front of the outer shell 1.

[0040] Furthermore, in order to facilitate the installation of the battery pack inside the housing 1, specifically, the top of the housing 1 is connected to a cover plate 2 via a pivot, and a handle 3 is fixedly connected to the front of the cover plate 2.

[0041] It is worth noting that, in order to ensure that the fan inside the outer frame 6 can operate normally, specifically, the inside of the outer shell 1 is connected by a fixing bolt 8 through a thread, and the surface of the fixing bolt 8 is connected by a fixing block 7 through a thread, and the side of the fixing block 7 is fixedly connected to the outer frame 6.

[0042] Finally, in order for the wind power cooling device to function properly, specifically, the outer frame 6 is fixedly connected to the surface of the connection port 9, the outer frame 6 is fixedly connected to the interior of the front protective frame 10, the front protective frame 10 is provided with a collar 12, the surface of the collar 12 is fixedly connected to the fan blade 13, and the outer frame 6 is fixedly connected to the interior of the rear protective frame 11.

[0043] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0044] Combination Figures 1-6 The specific usage process of the automotive battery cooling device of this embodiment is as follows:

[0045] 1. When using this type of car battery cooling device, the battery pack to be used needs to be installed inside the device first. This can be done by opening the cover 2, which is relatively convenient. At the same time, protective frames 15 are fixedly connected to both sides of the outer shell 1 of the device, and inner protective rods 16 are fixedly connected inside the protective frames 15. When the device is impacted, the protective frames 15 and inner protective rods 16 can withstand the impact, preventing the outer shell 1 from deforming due to the impact, thus providing good protection.

[0046] 2: Once the battery pack is installed inside the device, it can be put into use. During the operation of the device, the battery pack continuously supplies power and generates heat. At this time, the fan blades 13 inside the outer frame 6 can draw in air and blow it into the outer shell 1. At the same time, the heat dissipation holes 4 and heat dissipation fins 5 on both sides of the outer shell 1 can dissipate heat. However, after the device has been running for a long time, the heat dissipation effect of the fan and the heat dissipation holes 4 may not be enough to keep the internal temperature of the outer shell 1 within a suitable range, and the internal temperature of the outer shell 1 will slowly rise.

[0047] 3: At this point, the water pump 20 can be turned on. The water pump 20 will draw coolant from inside the water tank 17 and send it into the heat dissipation copper pipe 23. The heat dissipation copper pipe 23 and the heat absorber 22 will also continuously absorb heat. At the same time, when the coolant passes through the heat dissipation copper pipe 23 and the heat absorber 22, it will carry away some of the heat and recover it into the water tank 17. This process is a water circulation. Through the continuous water circulation of the water tank 17 and the water pump 20, the internal temperature of the outer casing 1 can be maintained at a suitable temperature when the fan cooling effect is not good. It can also work together with the fan cooling to achieve a stronger cooling effect and further enhance the cooling effect.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
