Description

A lithium-ion battery shell with good heat dissipation effect

Technical Field

The utility model relates to the technical field of lithium ion batteries, in particular to a lithium ion battery shell with good heat dissipation effect.

Background Art

Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charge and discharge process, Li+ is intercalated and deintercalated between the two electrodes: when charging, Li+ is deintercalated from the positive electrode and intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge.

During the operation of lithium-ion batteries, excessively high temperatures will have adverse effects on them, which requires the shell to dissipate heat. However, the traditional lithium-ion battery shell has poor heat dissipation effect, which can easily lead to excessive heat inside the battery and shorten the battery life. Therefore, we propose a lithium-ion battery shell with good heat dissipation effect to solve the above-mentioned problems.

When the temperature is too high, the signal is transmitted to the temperature control switch, and the temperature control switch starts the refrigeration plate for cooling. When the temperature is normal, no cooling is performed and the refrigeration plate does not need to be started in real time, thereby extending the service life of the refrigeration plate.

In a further technical solution, a warning light is fixedly connected to the right side of the housing, there are several warning lights, and the warning lights are electrically connected to the temperature sensor.

When the temperature is too high, a signal will be transmitted to the warning light, which will light up to remind you of the abnormal temperature. After a period of time, the temperature will return to normal and the warning light will go out. It can also be used to detect the internal cooling effect.

In a further technical solution, a cover is provided on the front of the battery body, a No. 1 protrusion is movably connected to the top of the cover, a No. 2 protrusion is fixedly connected to the bottom of the cover, a No. 1 groove is provided on the top of the shell, a No. 2 groove is provided on the bottom of the shell, the No. 1 protrusion is adapted to the No. 1 groove, and the No. 2 protrusion is adapted to the No. 2 groove.

When an internal electrical component fails, the cover can be quickly removed by pressing the No. 1 protrusion into the No. 1 groove, removing the No. 2 protrusion from the No. 2 groove, and then removing the cover from the housing, thereby facilitating maintenance work.

In a further technical solution, a connecting groove is provided on the top of the cover body, a spring is fixedly connected to the bottom of the connecting groove, the top of the spring is fixedly connected to the bottom of the No. 1 protrusion, and the No. 1 protrusion is slidably connected inside the connecting groove.

By pressing the No. 1 protrusion into the connecting groove, the spring is compressed and reset, and the cover body can be disassembled, thereby facilitating the disassembly of the cover body.

The beneficial effects of the utility model are:

1. The heat is dissipated through two heat dissipation nets. The heat dissipation fan on the left is turned on in real time to perform preliminary heat dissipation. When the temperature is high, the refrigeration sheet starts to cooperate with the heat dissipation fan to dissipate heat. When not in use, the refrigeration sheet is turned off, which saves energy and greatly improves the heat dissipation effect.

The warning light 11 is electrically connected to the temperature sensor 9, a cover body 12 is provided on the front side of the battery body 1, a No. 1 protrusion 13 is movably connected to the top of the cover body 12, a No. 2 protrusion 14 is fixedly connected to the bottom of the cover body 12, a No. 1 groove 15 is provided at the top of the shell 2, a No. 2 groove 16 is provided at the bottom of the shell 2, the No. 1 protrusion 13 is adapted to the No. 1 groove 15, and the No. 2 protrusion 14 is adapted to the No. 2 groove 16, a connecting groove 17 is provided at the top of the cover body 12, a spring 18 is fixedly connected to the bottom of the connecting groove 17, the top of the spring 18 is fixedly connected to the bottom of the No. 1 protrusion 13, and the No. 1 protrusion 13 is slidably connected to the inside of the connecting groove 17.

The working principle of the above technical solution is as follows:

When the lithium-ion battery in the housing 2 is in use, heat is dissipated through the two heat dissipation nets 4, and the heat dissipation fan 5 arranged on the left is turned on in real time to perform preliminary heat dissipation. When the temperature is high, the refrigeration sheet 6 is started to cooperate with the heat dissipation fan 5 to dissipate heat. When not in use, the refrigeration sheet 6 is turned off, which saves energy and greatly improves the heat dissipation effect. The refrigeration sheet 6, the cooling system 7 and the heat sink 8 absorb heat while cooling, thereby improving the cooling effect of the refrigeration sheet 6. The internal temperature is detected by the temperature sensor 9. When the temperature is too high, the signal is transmitted to the temperature control switch 10, and the temperature control switch 10 starts the refrigeration sheet 6 for cooling. When the temperature is normal, no cooling is performed, and the refrigeration sheet 6 does not need to be started in real time. In order to improve the service life of the refrigeration plate 6, when the temperature is too high, a signal will be transmitted to the warning light 11. The warning light 11 will emit a bright light to remind you of the abnormal temperature. After a period of time, when the temperature returns to normal, the warning light 11 will go out. It can also be used to detect the internal refrigeration effect. When the internal electrical components fail, by pressing the No. 1 protrusion 13, press it into the No. 1 groove 15, by removing the No. 2 protrusion 14 from the No. 2 groove 16, and then removing the cover body 12 from the shell 2, the cover body 12 can be quickly disassembled, which brings convenience to the maintenance work. By pressing the No. 1 protrusion 13 into the connecting groove 17, the spring 18 is compressed and reset, and the cover body 12 can be disassembled, thereby facilitating the disassembly of the cover body 12.
