Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.
In order to improve the heat dissipation effect of the battery module in the battery box on the basis of saving energy consumption as much as possible, technical reference is provided for the follow-up research of improving the heat dissipation of the battery box.
The first embodiment is as follows:
the battery box energy-saving heat dissipation device comprises a battery box body 1 and a battery module 2, wherein the battery box body 1 comprises a convex gradually-expanding air supply opening 102 and an air exhaust opening 101. Two guide vanes 3, two servo motors 4, two groups of meshing gears 5, a horizontal transmission rod 6 and a vertical transmission rod 7 are arranged in the air supply opening 102. The guide vane comprises an upper vane 301, a middle vane 302, a lower vane 303, an upper ball 304, a lower ball 305, an upper spring 306, a lower spring 307, an upper rotating shaft 308 and a lower rotating shaft 309.
The convex divergent air inlet 102 is composed of four trapezoidal pieces which are obliquely arranged and a rectangular piece which is vertically arranged.
The servo motor 4 drives the horizontal transmission rod 6, the meshing gear 5, the vertical transmission rod 7 and the guide vanes 3 in sequence according to a set function, and the guide vanes 3 swing left and right to drive air supply to swing left and right.
The middle blade 302 is formed by welding a rectangular blade and two small blades up and down, the middle blade 302 is connected with the upper blade 301 through an upper spring 306 and an upper rotating shaft 308, and is connected with the lower blade 303 through a lower spring 307 and a lower rotating shaft 309, and the middle blade 302 is attached to the upper inclined plane and the lower inclined plane as much as possible in the swing process of the guide vane so as to reduce air leakage.
The tail end of the upper blade 301 close to the inclined plane of the air port is provided with an upper ball 304, and the tail end of the lower blade 303 close to the inclined plane of the air port is provided with a lower ball 305, so that the friction force is reduced to facilitate the movement of the guide vane.
After the treated air enters from the air supply outlet, the servo motor 4 starts to work according to a set function, firstly the horizontal transmission rod 6 is driven to rotate, the horizontal transmission rod 6 drives the vertical transmission rod 7 to rotate through the meshing gear, and finally the two guide vanes 3 fixed on the vertical transmission rod 7 are driven to swing left and right by taking the vertical transmission rod 7 as an axis, and the two guide vanes 3 are always kept in a parallel relation. Due to the influence of the guide vanes 3, the air supply swings left and right along with the air supply, and the energy storage battery is cooled in the energy storage battery box 1.
A numerical simulation model of the energy-saving and heat-dissipating device of the battery box is established by SolidWorks software, and is properly simplified. And (3) performing numerical simulation on the heat dissipation condition inside the energy storage battery box by adopting software Fluent, programming udf program to simulate the movement rule that guide vanes drive inlet air to swing under the action of a servo motor at the moment when the air supply speed is 4m/s and the air supply temperature is 291K. The law of the guide vane motion is as follows:
in the x direction, Vx＝0.325568*4*cos(4.96*t)；
In the y direction, Vy＝(42-(0.325568*4*cos(4.96*t))2)1/2
As can be seen from fig. 4, after the steady state is reached, the maximum temperature of the battery module is 303K, which meets the heat dissipation requirement of the battery box, and in this case, the temperature of the battery module is not higher than 304K.
Comparative example 1
Different from the first embodiment, the motion rule that the guide vane drives the inlet air to swing under the action of the servo motor is not included; as can be seen from fig. 5, the same processing method as in the first embodiment is used for simplification and calculation during the numerical simulation, and when the calculation reaches the steady state without adding the motion rule that the guide vanes drive the inlet air to swing under the action of the servo motor, the maximum temperature of the battery module is 312K, which does not meet the heat dissipation requirement of the battery box (in this case, the temperature of the battery module is not higher than 304K). In addition, as is apparent from fig. 5, only a part of the regions in the battery box have a high temperature and do not satisfy the predetermined heat dissipation requirements.
Comparative example No. two
Different from the first embodiment, the movement rule that the guide vane drives the inlet air to swing under the action of the servo motor is not included, and the air supply temperature is reduced to 286K; as can be seen from fig. 6, the same processing method as in the first embodiment is used for simplification and calculation during the numerical simulation, and when the movement rule that the guide vanes drive the inlet air to swing without adding a servo motor and the air supply temperature is reduced to 286K, the maximum temperature of the battery module is 303K after the calculation reaches the steady state, which meets the heat dissipation requirement of the battery box (in this case, the temperature of the battery module is not higher than 304K). In addition, as is apparent from fig. 6, most of the regions in the battery box have low temperature, i.e., excessive heat dissipation, which results in energy waste.
Comparative example No. three
Different from the first embodiment, the movement rule that the guide vane drives the inlet air to swing under the action of the servo motor is not included, and the air supply speed is increased and reduced to 8 m/s; as can be seen from fig. 7, the same processing method as in the first embodiment is used for simplification and calculation during the numerical simulation, and when the movement rule that the guide vanes drive the inlet air to swing without adding a servo motor and the air supply speed is increased and decreased to 8m/s, the maximum temperature of the battery module is 303K after the calculation reaches the steady state, which meets the heat dissipation requirement of the battery box (in this case, the temperature of the battery module is not higher than 304K).
TABLE 1 comparison of key parameters of four examples
Through comparison, it can be seen that in the first comparative example, the heat dissipation effect cannot meet the specified requirements under the condition that the guide vanes are not adopted, although the heat dissipation conditions of most regions of the battery module meet the conditions, the temperatures of the regions are higher, the heat dissipation is not uniform, and the embodiment has a better and more uniform heat dissipation effect than the first comparative example. The second embodiment has the advantages that the heat dissipation effect meets the specified requirements under the condition that the guide vanes are not adopted and the air supply speed is increased, and the first embodiment and the second embodiment can save more energy under the condition that the first embodiment and the second embodiment can meet the specified heat dissipation requirements. In the third embodiment, the heat dissipation effect meets the specified requirements under the condition that the guide vanes are not adopted and the air supply temperature is reduced, but the temperature of most regions in the battery box is lower, namely excessive heat dissipation is realized, so that energy waste is caused, and the first embodiment and the third embodiment can save more energy under the condition that the specified heat dissipation requirements can be met.
