Description
Technical field
The utility model relates to battery technology fields, and in particular to a kind of lithium battery with temperature control device.
Background technique
Lithium battery is widely used now comprising the elements such as a battery case and electrolyte composition passes through metal glass
The lid of glass sealing-in is sealed battery case, thus depositing in electrolyte vacuum in battery case, due to lithium battery
The charging for needing to recycle for a long time, when the pressure in lithium battery is excessive, often there is a phenomenon where hollowings to deform for lithium battery, generally
Such case occurs, and is since the temperature of lithium battery during the charging process is excessively high, and duration is too long causes for charging, but
We can not generally change extraneous temperature, and people are for convenience, usually charge at night, often once filling more than 10
A hour, nobody's midnight can get up to pull out power supply, because the position many times charged is farther out, fills and pull out also inconvenience.
Chinese patent Authorization Notice No. CN 206040864U, authorized announcement date are that the utility model on March 22nd, 2017 is public
A kind of lithium battery is opened comprising a shell has an accommodation space；One positive plate and a negative plate, are respectively positioned on accommodation space
It is interior；One partition is contained in accommodation space, and between positive plate and negative plate；Most electrolyte levels in accommodation space,
Fill each gap in accommodation space；Two poles are mutually connected with positive plate and negative plate respectively, and each pole at least partly appears
Shell out, to connect two electric wires, a control flume is set to shell, is equipped with coolant liquid in control flume, empty to accommodating by coolant liquid
Interior electrolyte carries out temperature control.
Coolant liquid control flume in the device is located at holding tank two sides and bottom space, cold when electrolyte temperature is excessively high
But liquid can only play expected cooling effect to the electrolyte of expected contact, and for being located in the middle apart from coolant liquid apart from mistake
Remote electrolyte cooling effect just remains to be discussed, and such bring consequence is exactly that the whole cooling rate of lithium battery is excessively slow, nothing
Method is met the requirements.
Summary of the invention
The purpose of the utility model is to overcome the defect of existing technology and deficiency, provide a kind of structure is simple, temperature control effect is good,
The stable lithium battery with temperature control device of quality.
In order to achieve the above object, the technical solution of the utility model is: a kind of lithium battery with temperature control device, packet
Shell is included, the accommodation space full of electrolyte is provided in the shell, intercommunicating pore is provided at the top of the accommodation space, is held
Receive the positive plate and negative plate kept apart by partition that be internally provided in space, the positive plate and negative plate respectively with set
The pole set in cover top portion is fixedly connected, it is characterised in that: labyrinth heat exchanger channels, the fan are provided in the accommodation space
The inside of palace heat exchanger channels is full of coolant liquid, and the external of labyrinth heat exchanger channels is full of electrolyte.
The both ends outlet of the labyrinth heat exchanger channels is connected with the liquid injection port of setting on the shell respectively.
Sealing-plug is provided in the connecting hole and liquid injection port.
Anticorrosion separation layer is provided on the outer wall of the labyrinth heat exchanger channels.
The utility model compared with prior art, has the advantage that
1, the utility model impregnates labyrinth heat exchanger channels in the electrolytic solution by setting, can greatly increase coolant liquid and
The contact area of electrolyte improves heat exchange efficiency, and temperature control effect is more preferable, and the fluid injection of the both ends outlet of labyrinth heat exchanger channels is arranged in
Mouth can be convenient the replacement of coolant liquid, improve the stability of equipment.
2, anticorrosion separation layer is arranged in the utility model on the outer wall of labyrinth heat exchanger channels, can effectively stop electrolyte
To the corrosion attack of channel outer wall, extend the service life of equipment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: shell 1, electrolyte 2, accommodation space 3, intercommunicating pore 4, partition 5, positive plate 6, negative plate 7, pole 8, labyrinth
Heat exchanger channels 9, coolant liquid 10, liquid injection port 11, sealing-plug 12, anticorrosion separation layer 13.
Specific embodiment
The utility model is described in further detail below in conjunction with Detailed description of the invention and specific embodiment.
Referring to Fig. 1, a kind of lithium battery with temperature control device, including shell 1 is provided with full of electrolysis in the shell 1
The accommodation space 3 of liquid 2, the top of the accommodation space 3 are provided with intercommunicating pore 4, and being internally provided with for accommodation space 3 passes through partition
5 positive plates 6 and negative plate 7 kept apart, the positive plate 6 and negative plate 7 respectively with pole 8 that the top of shell 1 is set
It is fixedly connected, labyrinth heat exchanger channels 9 is provided in the accommodation space 3, the inside of the labyrinth heat exchanger channels 9 is full of coolant liquid
10, the external of labyrinth heat exchanger channels 9 is full of electrolyte 2, and the both ends outlet of the labyrinth heat exchanger channels 9 is respectively with setting in shell
Liquid injection port 11 on 1 is connected, and is provided with sealing-plug 12 in the intercommunicating pore 4 and liquid injection port 11, in order to improve making for channel
With the service life, anticorrosion separation layer 13 is provided on the outer wall of labyrinth heat exchanger channels 9.
The utility model is injected electrolyte 2 in accommodation space 3 by intercommunicating pore 4 in assembling, then passes through liquid injection port 11
Coolant liquid 10 is injected in labyrinth heat exchanger channels 9, and is sealed intercommunicating pore 4 and liquid injection port 11 with sealing-plug 12.It is filled to battery
When electric, when electrolyte 2 when the temperature is excessively high, by the coolant liquid 10 in labyrinth heat exchanger channels 9 to the electrolyte 2 in accommodation space 3
Temperature control is carried out, the service life of lithium battery is so extended, and is also avoided because the temperature of lithium battery is excessively high, and leads
The explosion danger of cause.
