The concrete meaning of language in the present invention.
As shown in Figure 1, present embodiments providing a kind of cylindrical lithium battery heat-exchange system, including total inlet tube 1, main drain pipe
2 and a plurality of heat exchange units 3.
It is provided with total inlet 101 for feed liquor on total inlet tube 1, is provided on main drain pipe 2 for going out the total of liquid
Liquid outlet 201.Total inlet tube 1 and main drain pipe 2 are arranged in parallel, and a plurality of heat exchange units 3 go out liquid along total inlet tube 1 and always
The length direction of pipe 2 is equally spaced, and total inlet tube 1 is located at one end of heat exchange unit 3, and main drain pipe 2 is located at the another of heat exchange unit 3
One end.
Heat exchange unit 3 includes dividing inlet tube 4, separating liquid pipe 5 and a plurality of lithium battery mould groups 6.It separates liquid pipe 5 and divides feed liquor
Pipe 4 is arranged in parallel and is located at the two sides of 6 top of lithium battery mould group.The pipe shaft of point inlet tube 4 and total inlet tube 1 passes through the
The connection of one liquid inlet joint 10 separates liquid pipe 5 and is connect with the pipe shaft of main drain pipe 2 by the first liquid outlet connector 11.Inlet tube 4 is divided to hang down
Directly in total inlet tube 1, liquid pipe 5 is separated perpendicular to main drain pipe 2.
In conjunction with Fig. 2, lithium battery mould group 6 includes battery fixing bracket 601 and answering in battery fixing bracket 601 is arranged in
Several battery cores 602.Battery core 602 is horizontally disposed cylindrical body.
In conjunction with Fig. 3 and Fig. 4, heat exchange bend pipe 7 is provided in lithium battery mould group 6.Heat exchange bend pipe 7 and the surface of battery core 602 connect
Touching and heat exchange bend pipe 7 are waveform, the cylindrical surface cooperation of trough and telecommunications 602.The pore of heat exchange bend pipe 7 is rectangle, is changed
The side of hot-bending pipe 7 is fitted closely with 602 surface of battery core, to increase the contact area of heat exchange bend pipe 7 and battery core 602.But it is real
There are errors in the production process of border, cause heat exchange bend pipe 7 that cannot be adjacent to 602 surface of telecommunications, so that the consistency of heat exchange is influenced,
Therefore the gap between battery core 602 and the bend pipe 7 that exchanges heat can be filled by thermal conductive silicon rubber mat or casting glue etc..
In conjunction with Fig. 5, the channel 14 communicated inside the bend pipe 7 that exchanges heat by multiple complementations is formed, and an effect is prevented because of pipe
Road is wide to cause liquid flow is out-of-date to have bubble, causes bladdery local heat transfer effect relatively poor, another effect is to increase
System pressure promotes the flow velocity of heat exchanging liquid, final to increase the coefficient of heat transfer to promote heat transfer effect.
One end of heat exchange bend pipe 7 connect by the second liquid inlet joint 12 with inlet tube 4 is divided, the other end of heat exchange bend pipe 7 and
Liquid pipe 5 is separated to connect by the second liquid outlet connector 13.Second liquid inlet joint 12 and the second liquid outlet connector 13 are respectively positioned on lithium battery mould
The top of group 6.Heat exchange 7 both ends of bend pipe are provided with bending part 8, and the wherein setting of bending part 8 goes out in the second liquid inlet joint 12 and second
The lower section of liquid connector 13.The supporting element 9 for promoting 8 support force of bending part is provided on bending part 8.
A plurality of heat exchange bend pipes 7 liquid pipe 5 and divide the length direction of inlet tube 4 to be equally spaced along separating.
Wherein, the first liquid inlet joint 10, the first liquid outlet connector 11, the second liquid inlet joint 12 and the second liquid outlet connector 13 are
Metal joint is fixed on pipe shaft by yoke configurations.
In the present embodiment, total inlet tube 1, main drain pipe 2, divide inlet tube 4 and separate the medium in liquid pipe 5 for liquid Jie
Matter, the liquid medium select 50% concentration glycol water, specific heat capacity c=3300J/ (kgK).
According to formula Q=cm △ T, wherein Q is battery-heating amount, and c is heat transferring medium specific heat capacity, and m is heat transferring medium
Quality, △ T are the differences of final temperature after the fashionable initial temperature of heat exchanging medium flow and outflow, and the specific heat capacity for comparing air is 1003J/
(kg·K).(battery types that use, quantity, type of attachment the are just the same) calorific value so in same a set of battery system
Unanimously, while assuming that air and liquid per minute flow into quality also mutually simultaneously as the ratio of 50% concentration glycol water
Thermal capacitance is 3.3 times of air, therefore uses 50% concentration glycol water and the air heat-exchange comparison discovery of phase homogenous quantities, liquid
0.3 when the difference of final temperature is with air heat-exchange after the fashionable initial temperature of heat exchanging medium flow and outflow.Such benefit is to change
While thermal effect is good, temperature consistency is influenced micro- by heat exchange medium temperature difference between the cylindrical lithium battery of different location
Its is micro-.
The course of work of the cylindrical lithium battery heat-exchange system are as follows:
Liquid medium enters total inlet tube 1 from total inlet 101, divides inlet tube 4 subsequently into various heat exchange unit 3
In.
In the liquid medium of same heat exchange unit 3 from dividing inlet tube 4 to enter heat exchange bend pipe 7, exchange heat.Liquid after heat exchange
Body medium enters from heat exchange bend pipe 7 separates liquid pipe 5.
The liquid medium of various heat exchange unit separated in liquid pipe 5 enters main drain pipe 2, finally from main drain pipe 2
Total liquid outlet 201 is discharged.
Due to different heat exchange units 3 be it is in parallel, each heat exchange unit 3 it is relatively independent, do not exchanged heat by other
The influence of unit 3.And the heat exchange bend pipe 7 in each heat exchange unit 3 is also in parallel, therefore each heat exchange bend pipe 7 is relatively independent,
It is not influenced by other heat exchange bend pipes 7.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is also included in the patent protection scope of the utility model.
