Technical Field
[0001] This utility model relates to the field of polymer battery technology, specifically to a polymer battery with a built-in separator for multi-directional heat dissipation. Background Technology
[0002] Lithium polymer batteries, also known as high-molecular lithium batteries, are a type of chemical battery. Compared to previous batteries, they are characterized by high energy density, miniaturization, and lightweight design. Lithium polymer batteries are also ultra-thin, allowing multiple batteries to be combined and installed together to create battery packs of different shapes and capacities to meet the needs of various products.
[0003] Current polymer battery packs with built-in separators generate a lot of heat during use because they are composed of multiple lithium polymer batteries. Some existing polymer battery packs with built-in separators do not have multi-directional heat dissipation capabilities, resulting in poor heat dissipation and posing certain safety hazards. Utility Model Content
[0004] To address the problem that some existing polymer battery packs with built-in separators lack multi-directional heat dissipation capabilities, resulting in poor heat dissipation and potential safety hazards, the purpose of this invention is to provide a polymer battery with built-in separators for multi-directional heat dissipation.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a polymer battery with built-in separator and multi-directional heat dissipation, including a shell, a sealing cover, and a battery body. The sealing cover is fitted onto the top of the shell, and the battery body is placed inside the shell. A support plate is fixedly installed inside the shell. The support plate is hollowed out, and multiple partitions are fixedly installed on the upper surface of the support plate at equal intervals. Multiple heat dissipation channels are opened in the multiple partitions at equal intervals. Multiple heat dissipation holes are opened on both sides of the multiple partitions, and the heat dissipation holes are connected to the corresponding heat dissipation channels. Air outlets are opened on the upper part of both sides of the shell. A conical groove is opened inside the shell. An air inlet is opened at the bottom of the shell and is connected to the conical groove. A fan is fixedly installed at the bottom of the conical groove.
[0006] Preferably, bolts are threaded at all four corners of the sealing cover, and the bolt threads are inserted into the top four corners of the outer shell. A sealing cap is fitted on the top of each of the four bolts. Two symmetrically distributed terminals are fixedly installed on the sealing cover, and a handle is hinged to the upper surface of the sealing cover.
[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0008] In this invention, a fan can be activated to allow external air to pass through the air inlet and be blown into the casing by the fan. The airflow enters the heat dissipation channel in the partition and is blown onto the surface of the battery body through the heat dissipation holes, thereby achieving multi-directional heat dissipation of the battery body from the bottom and sides, thus improving the heat dissipation effect of the battery pack.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example: Figure 1-5As shown, this utility model provides a polymer battery with built-in separators for multi-directional heat dissipation, including a shell 1, a sealing cover 2, and a battery body 7. The sealing cover 2 is fitted onto the top of the shell 1, and the battery body 7 is placed inside the shell 1. The battery body 7 is a conventional polymer battery, mainly including a cell, a shell, and positive and negative tabs. The shell can completely seal and wrap the cell, and the positive and negative tabs are connected to the positive and negative terminals of the cell. The shell is usually made of an ultra-thin graphene film, which has high thermal conductivity, facilitating heat dissipation of the battery body 7. A support plate 10 is fixedly installed inside the shell 1. The support plate 10 is hollow, and multiple equally spaced separators 8 are fixedly installed on the upper surface of the support plate 10. The separators 8 divide the internal space of the shell 1 into multiple battery compartments, and the battery body 7 can be placed inside the battery compartments. Multiple equally spaced heat dissipation channels 801 are opened in each of the multiple separators 8, and multiple heat dissipation channels 801 are opened on both sides of the multiple separators 8. Multiple heat dissipation holes 802 are distributed in an array, and the heat dissipation holes 802 are connected to the corresponding heat dissipation channels 801. Air outlets 101 are provided on the upper parts of both sides of the outer shell 1. A conical groove 103 is provided inside the outer shell 1. An air inlet 102 is provided at the bottom of the inner side of the outer shell 1, and the air inlet 102 is connected to the conical groove 103. A fan 9 is fixedly installed at the bottom of the conical groove 103. When in use, the fan 9 can be turned on, so that the external air passes through the air inlet 102 and is blown into the outer shell 1 by the fan 9. The airflow enters the heat dissipation channel 801 in the partition 8 and blows onto the surface of the battery body 7 through the heat dissipation holes 802 to cool the battery body 7. At the same time, the hot air inside the outer shell 1 can be discharged through the air outlets 101 to realize the air circulation inside the outer shell 1. Thus, the purpose of multi-directional heat dissipation of the battery body 7 from the bottom and sides can be achieved, thereby improving the heat dissipation effect of the battery pack.
[0018] Dustproof nets 6 are fixedly installed inside the two air outlets 101 and at both ends of the air inlet duct 102. The dustproof nets 6 can prevent external dust and other impurities from entering the outer casing 1 through the air outlets 101 and the air inlet duct 102.
[0019] Bolts 11 are threaded at all four corners of the sealing cover 2, and the bolts 11 are threaded into the four corners of the top of the outer shell 1. The sealing cover 2 is installed on the outer shell 1 by means of the bolts 11.
[0020] Each of the four bolts 11 is fitted with a sealing cap 5, which protects the bolts 11.
[0021] Two symmetrically distributed terminals 4 are fixedly installed on the sealing cover 2. The two terminals 4 are positive and negative terminals 4, which are used to connect electrical equipment. The positive and negative ears of the battery body 7 inside the outer casing 1 can be connected to the corresponding positive and negative terminals 4 through wires.
[0022] A handle 3 is hinged to the upper surface of the sealing cover 2, which makes it easy to pick up the device.
[0023] Working principle: This utility model can install multiple battery bodies 7 inside the outer casing 1, and connect the positive and negative terminals of the battery bodies 7 to the corresponding positive and negative terminals 4 through wires. The sealing cover 2 is installed on the outer casing 1 by bolts 11, and a sealing cap 5 can be fitted on the bolts 11. When in use, the fan 9 can be turned on, so that the outside air passes through the air inlet 102 and is blown into the outer casing 1 by the fan 9. The airflow enters the heat dissipation channel 801 in the partition 8 and blows onto the surface of the battery body 7 through the heat dissipation hole 802 to cool the battery body 7. At the same time, the hot air inside the outer casing 1 can be discharged through the air outlet 101 to realize the air circulation inside the outer casing 1. Thus, the purpose of multi-directional heat dissipation of the battery body 7 from the bottom and side can be achieved, thereby improving the heat dissipation effect of the battery pack.
