Description

Technical Field

[0001] This utility model relates to the field of battery heat dissipation technology, specifically to a battery PACK device that facilitates heat dissipation. Background Technology

[0002] As new energy technologies mature and photovoltaic systems are deployed and installed on a large scale, home energy storage battery systems are gradually becoming an important tool for achieving energy independence and improving energy efficiency. These systems utilize renewable resources such as solar and wind power to store excess electrical energy, and can also be used as backup power after grid outages.

[0003] For example, a heat dissipation system and energy storage battery pack disclosed in CN214505600U include a water inlet component, a water outlet component, and an alternating switch module; wherein the alternating switch module is connected to the water inlet component and the water outlet component respectively, and the water inlet component and the water outlet component are connected to the battery module respectively.

[0004] The aforementioned heat dissipation system and energy storage battery pack use alternating switching modules to control the inlet and outlet water components, alternately supplying coolant to the battery module. This ensures that the temperature at the inlet and outlet water components of the battery module is essentially the same, thereby maintaining a relatively uniform temperature throughout the battery module and extending its lifespan. However, this type of liquid cooling solution has the following problems: Firstly, the liquid cooling system requires a series of specialized equipment and consumables, including inlet and outlet water components, a circulation pump, and coolant, resulting in a high initial hardware investment. Secondly, the piping layout of the liquid cooling system is complex and requires extremely high sealing performance; if pipe aging or loose connections occur, coolant leakage is highly likely. Summary of the Invention

[0005] In view of the above-mentioned technical problems in the existing technology, the present invention provides a battery PACK device that facilitates heat dissipation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A battery pack device with convenient heat dissipation is provided, including a housing with a housing space formed inside. A partition is provided inside the housing, which divides the housing space into an independent upper housing cavity and a lower housing cavity. A battery pack is provided in the lower housing cavity, which includes multiple battery groups connected in series. At least one cooling fan is provided in the upper housing cavity, and a ventilation opening is provided on the side wall of the housing corresponding to the upper housing cavity. The device also includes multiple heat-conducting plates, each of which is attached to the side wall of each battery group, and the top of the heat-conducting plate penetrates the partition and extends into the upper housing cavity.

[0008] Preferably, a mounting bracket is provided inside the upper receiving cavity, and the battery pack is fixedly installed inside the receiving cavity by means of the mounting bracket.

[0009] Preferably, the battery pack is also equipped with a controller for controlling the charging and discharging of the battery pack and a display for displaying the battery pack power level; the controller and the display are separated from the battery pack by a heat insulation plate.

[0010] Preferably, the top of the housing is provided with a charging / discharging port, which is electrically connected to the controller via a wire.

[0011] Preferably, the outer walls on both sides of the housing are also provided with lifting components, which include connecting blocks fixedly disposed on the outer walls of the housing and annular handles hinged to the connecting blocks.

[0012] Preferably, the bottom of the housing is also provided with support blocks, with two support blocks located at both ends of the bottom of the housing to increase the ground clearance of the housing.

[0013] Preferably, the heat-dissipating battery PACK device also includes a cover for covering the openings of the upper and lower receiving cavities and is detachably connected to the housing.

[0014] The beneficial effects of this utility model are:

[0015] This invention discloses a battery pack device with convenient heat dissipation. A partition divides the housing space into two independent upper and lower cavities. The battery pack is housed in the lower cavity, while the cooling fan is located in the upper cavity. When the battery pack generates heat during charging and discharging, a heat-conducting plate tightly attached to the side wall of the battery pack conducts the heat to its top. Since the top of the heat-conducting plate penetrates the partition and extends into the upper cavity, the heat is transferred along the extension of the heat-conducting plate into the upper cavity. At this time, the cooling fan activates, quickly dissipating the heat concentrated on the top of the heat-conducting plate through the heat dissipation vents on the side wall of the housing. Compared to liquid cooling solutions in the prior art, this invention eliminates the need for complex water inlet and outlet components, circulation pumps, and coolant, significantly reducing initial hardware investment and subsequent maintenance costs.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] This embodiment provides a battery pack device that facilitates heat dissipation, such as... Figures 1 to 5 As shown, the device includes a housing 1, which has a receiving space. The receiving space contains a battery pack 5 capable of charging and discharging, and at least one cooling fan 7. The cooling fan 7 is used to dissipate heat from the battery pack 5 during charging and discharging, so as to prevent the performance of the battery pack 5 from deteriorating due to excessive temperature during charging and discharging.

[0024] Furthermore, a partition 2 is provided inside the housing 1. The partition 2 is arranged along the length of the housing 1, dividing the accommodating space into an independent upper accommodating cavity 3 and a lower accommodating cavity 4. The battery pack 5 is arranged in the lower accommodating cavity 4, while the cooling fan 7 is arranged in the upper accommodating cavity 3. The battery pack 5 is composed of multiple battery groups connected in series.

[0025] Furthermore, the heat-dissipating battery PACK device also includes multiple heat-conducting plates 6, wherein each heat-conducting plate 6 is attached to the side wall of each battery pack, and the top of the heat-conducting plate 6 penetrates through the partition 2 and extends into the upper receiving cavity 3. The heat-conducting plate 6 can guide the heat emitted by the battery pack 5 from the lower receiving cavity 4 to the upper receiving cavity 3, and then the heat is discharged from the upper receiving cavity 3 by the cooling fan 7.

[0026] To ensure the cooling fan 7 can effectively dissipate heat from the upper cavity 3, a heat dissipation vent 8 communicating with the upper cavity 3 is provided on the outer wall of the housing 1, with the cooling fan 7 positioned near the vent 8. During operation, after the heat-conducting plate 6 guides the heat generated by the battery pack 5 to the upper cavity 3, the cooling fan 7 starts, its blades rotating to generate suction, directly drawing away the hot air from the heat-conducting plate 6. The hot air is propelled by the blades and flows along the airflow direction to the heat dissipation vent 8 on the outer wall of the housing 1. Since the heat dissipation vent 8 is connected to the cavity, the hot air is discharged outside the housing 1 through the vent 8, thus carrying the heat from the heat-conducting plate 6 out of the device. By continuously drawing away heat and dissipating it through the vent 8, the cooling fan 7 effectively dissipates heat from the battery pack 5, ensuring that the battery pack 5 remains at a safe operating temperature during charging and discharging.

[0027] Furthermore, a mounting bracket 9 is also provided in the lower receiving cavity 4. The battery pack 5 is fixedly installed in this receiving cavity by the mounting bracket 9 to prevent the battery pack 5 inside from shaking when the housing 1 shakes, thereby preventing the battery pack 5 from being bumped and affecting the performance of the battery pack 5.

[0028] Since the battery pack 5 is fixed in the cavity by the mounting bracket 9, a certain gap can be formed between the battery pack 5 and the inner wall of the cavity, which helps air circulation and assists in heat dissipation of the battery pack 5.

[0029] Furthermore, the battery pack 5 is also equipped with a controller 10 for controlling the charging and discharging of the battery pack 5 and a display 11 for displaying the battery pack 5's power level; the controller 10 and the display 11 are separated from the battery pack 5 by a heat insulation plate 12. The heat insulation plate 12 is made of a high-temperature resistant and heat-insulating material, such as ceramic fiber board, which can effectively block the heat generated by the battery pack 5 from being transferred to the controller 10 and the display 11, ensuring their normal operation.

[0030] It should be noted that both the controller 10 and the display 11 are existing technologies. The controller 10 is actually a control switch used to control the conduction of the battery pack 5 circuit, while the display 11 is actually an LCD panel capable of displaying the battery pack 5 power level. Both the controller 10 and the display 11 are purchased components. For example, the controller 10 is a MAX1788 smart battery pack controller, and the display 11 is a LY7 LCD power level display, used in this embodiment, and will not be described in detail here.

[0031] Furthermore, a charging / discharging port 13 is provided on the top of the housing 1, and the charging / discharging port 13 is electrically connected to the controller 10 via a wire. In use, when the battery pack 5 needs to be charged, an external power source charges the battery pack 5 by connecting to the charging / discharging port 13; when it is necessary to power an external device, take an adapter wire, firmly insert one end into the charging / discharging port 13, and correctly connect the other end to the external device. Then, turn on the power switch of the controller 10, and the electrical energy stored in the battery pack 5 will be stably output to the external device through the charging / discharging port 13 under the control of the controller 10, meeting its power needs.

[0032] Furthermore, to facilitate the movement of the device, lifting components 14 are provided on the outer walls of both sides of the housing 1. The lifting components 14 include connecting blocks 140 and annular handles 141. The connecting blocks 140 are fixed to the housing 1 by bolts or welding, while the annular handles 141 are hinged to the connecting blocks 140.

[0033] Furthermore, a support block 15 is provided at the bottom of the housing 1. Two support blocks 15 are located at both ends of the bottom of the housing 1 to increase the ground clearance of the housing 1. By providing support blocks 15 at the bottom of the housing 1, direct contact between the housing 1 and the bottom surface is avoided, effectively preventing ground moisture from entering the equipment and preventing short circuits or performance degradation of components such as the battery pack 5 due to moisture. The support block 15 is preferably made of rubber, and its bottom can also have anti-slip texture, which not only firmly grips the ground but also ensures that the equipment will not easily slip during use.

[0034] Furthermore, the heat-dissipating battery pack device also includes a cover 16 for covering the opening of the receiving space and detachably connected to the housing 1. By providing the cover 16, the cover 16 can form physical protection, isolating the battery pack 5 and other components inside the device from the external environment, preventing dust, moisture or foreign objects in the outside air from entering the device and damaging the battery pack 5 and other components inside the device.
