Abstract
Present invention discloses a kind of battery pack liquid cooling heat exchange tube structure, battery pack has multiple battery units to constitute, and each battery unit is each attached on bottom plate, and the bottom plate is double panel structure, is equipped with cooling tube between the doubling plate of the bottom plate.The uniform temperature of cooling effect can be improved with liquid cooling heat exchange tube structure for battery pack of the present invention, furthermore liquid cooling pipeline is placed in Battery case base plate interior, with it is completely separated inside battery pack, to effectively prevent because leakage is dangerous to battery pack bring, so that battery pack work safety, stabilization, reliable.
Description
Technical field
The present invention relates to power battery fields.
Background technique
Power lithium-ion battery belongs to the core component of new-energy automobile, and lithium ion normal working temperature range only has -20
~60 DEG C, the temperature of battery influences clearly battery performance.When temperature is higher than 60 DEG C, internal electrochemical reaction speed
It can further increase, temperature continues to rise, and will seriously affect battery, or even the dangerous situations such as explosion on fire occur.
In addition, single battery arrangement is compact in battery, temperature distribution is non-uniform in battery pack then will lead to single battery pressure
Difference becomes larger, and then reduces battery pack overall performance, reduces electric car course continuation mileage.Therefore, battery pack thermal management system is electricity
Pond group important component.Battery pack temperature is reduced, the temperature difference in battery pack is reduced, is had to the performance for improving battery pack important
Meaning.
In the prior art, mainly have in battery thermal management system natural air cooled and two kinds of liquid cooling.Wherein it is limited by battery pack
Interior space limitation, windage is larger, and cooling effect is poor, and heat dissipation is uneven.Liquid cooling coolant liquid can only flow in one direction, coolant liquid
Flow resistance is larger and the inside battery temperature difference is also larger, and the uniformity of internal temperature of battery can not be effectively ensured.
Summary of the invention
The technical problem to be solved by the present invention is to realize a kind of to cool down battery pack liquid cooling reliable, that work safety is stable
Heat exchange tube structure.
To achieve the goals above, the technical solution adopted by the present invention are as follows: a kind of battery pack liquid cooling heat exchange tube structure, electricity
Pond group has multiple battery units to constitute, and each battery unit is each attached on bottom plate, and the bottom plate is double panel structure, institute
It states and is equipped with cooling tube between the doubling plate of bottom plate.
The bottom plate is equipped with muti-piece, and bottom plate described in muti-piece is arranged side by side, and the battery unit is separately fixed at different bottoms
On plate.
The cooling tube is evenly distributed in bottom plate at S-shaped, the water inlet on the both ends distribution connecting bottom board of the cooling tube
Interface and water outlet mouthpiece, the water inlet interface and water outlet mouthpiece are located at the diagonal position of bottom plate.
Bottom plate two sides arranged side by side are equipped with return water supervisor and supervisor of intaking, and the return water supervisor is connected each by threeway
The water inlet interface that threeway connects each bottom plate was responsible in the return water interface of bottom plate, the water inlet.
The uniform temperature of cooling effect can be improved with liquid cooling heat exchange tube structure for battery pack of the present invention, and furthermore liquid cooling pipeline is placed in
Battery case base plate interior, it is completely separated with battery pack inside, to effectively prevent because leakage is endangered to battery pack bring
Danger, so that battery pack work safety, stabilization, reliable.
Detailed description of the invention
Below to width attached drawing every in description of the invention expression content and figure in label be briefly described:
Fig. 1 is battery pack liquid cooling heat transfer tube structure diagram；
Label in above-mentioned figure is equal are as follows: 1, return water supervisor；2, return water interface；3, water inlet supervisor；4, water inlet interface；5, bottom
Plate；6, cooling tube.
Specific embodiment
Below against attached drawing, by the description of the embodiment, for example related each component of a specific embodiment of the invention
Shape, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle, manufacturing process and
Operate with method etc., is described in further detail, to help those skilled in the art to inventive concept of the invention, technology
Scheme has more complete, accurate and deep understanding.
Battery pack has multiple battery units to constitute, and each states battery unit and is each attached on bottom plate 5, and bottom plate 5 is equipped with muti-piece,
Muti-piece bottom plate 5 is arranged side by side, and battery unit is separately fixed on different bottom plates 5.As shown in Figure 1, bottom plate 5 is double-deck hardened
Structure is equipped with cooling tube 6 between the doubling plate of bottom plate 5, and liquid cooling pipeline is placed in inside Battery case bottom plate 5, and complete inside battery pack
It separates entirely, to effectively prevent because leakage is dangerous to battery pack bring.
Cooling tube 6 is evenly distributed in bottom plate 5 at S-shaped, and the cooling water in adjacent cooling tube 6 flows on the contrary, can be improved
The uniform temperature of cooling effect.In order to facilitate later period installation, water inlet interface 4 and go out that the both ends of cooling tube 6 are distributed on connecting bottom board 5
Water interface, water inlet interface 4 and water outlet mouthpiece are located at the diagonal position of bottom plate 5, and 5 two sides of bottom plate arranged side by side are responsible for equipped with return water
1 is responsible for the 1 return water interface 2 that each bottom plate 5 is connected by threeway with water inlet supervisor 3, return water, and water inlet is responsible for 3 and crosses threeway connection often
The water inlet interface 4 of a bottom plate 5.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
It is within the scope of the present invention into the conception and technical scheme of the invention are directly applied to other occasions.
