The embodiments described above are a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Example 1

Fig. 1 is a perspective view of an energy storage container provided by an embodiment of the present invention. In order to facilitate the observation of the structure of various components inside the box of the energy storage container, Fig. 1 shows that the top and front side walls of the energy storage container are removed. And the structure seen behind the front side wall of the cold air duct. As shown in FIG. 1 , the energy storage container of this embodiment includes a box body 4 , a battery cluster 3 , a refrigeration device 1 and a cold air duct 2 . The battery cluster 3 , the refrigeration device 1 and the cold air duct 2 are arranged inside the box body 4 , and the cold air duct 2 is arranged above the battery cluster 3, the air outlet 11 of the refrigeration equipment is communicated with the air inlet 21 of the cold air duct, and a plurality of vents 22 are arranged on the cold air duct 2 at intervals along the length direction of the cold air duct 2, and in the cold air The inner wall of the duct 2 is provided with an air baffle 23, the plate surface direction of the air baffle 23 has an included angle with the length direction of the cold air duct 2, and at least one of the air baffle 23 and the plurality of vents is located in the cold air duct 2. The vents 22 on the upstream or midstream side of the flow correspond.

In the energy storage container, the inner wall of the cold air duct is provided with an air baffle having an included angle with the cold air duct, and at least one of the air baffle and the plurality of vents is located on the upstream side or the midstream side of the cold air duct for ventilation. Therefore, when the cold air from the refrigeration equipment flows along the length direction in the cold air duct, when it flows through the upstream or midstream, it can change its direction locally under the shielding effect of the windshield. Compared with the case where the windshield is not provided in the prior art, the included angle of the air outlet direction is reduced, so it is easier to divert the flow to the vents located in the upstream or midstream, which improves the accumulation of a large amount of cold air in the cold air duct in the prior art. In the downstream situation, the battery cluster corresponding to the upstream or midstream of the cold air duct can also be effectively cooled, so the energy storage container of this embodiment is evenly cooled and has a good cooling effect.

As shown in FIG. 1 , generally, the interior of the box 4 of the energy storage container can be divided into an electrical room 41 and a battery room 42 for accommodating the battery cluster 3 by a partition wall 43 , and a battery management unit can be arranged in the electrical room 41 (not shown) etc., the battery management unit is electrically connected to the refrigeration equipment 1 , and the operation of the refrigeration equipment 1 is controlled according to the temperature of the battery in the battery box 31 . In addition, the battery chamber 42 may be provided with a plurality of battery clusters 3 arranged in an array. In this embodiment, the battery chamber 42 is provided with 10 rows and 2 columns of battery clusters as an example for description. The situation of the battery cluster is similar and will not be repeated here. In addition, in FIG. 1, the column direction of the battery cluster arrangement is represented by the letter "C", and the row direction of the battery cluster arrangement is represented by the letter "R".

In the energy storage container of this embodiment, the refrigeration device 1 is the refrigeration source of the energy storage container, and the air outlet 11 of the refrigeration device 1 is communicated with the air inlet 21 of the cold air duct, so as to transport the cold air into the cold air duct 2 . The refrigeration equipment 1 here can choose a refrigeration and air-conditioning unit. For the installation position of the refrigeration equipment 1, the refrigeration equipment 1 can be selected to be installed in the battery compartment 42, specifically to the side of the battery cluster 3, and each battery cluster 3 is provided with a refrigeration equipment 1 and a cold air duct 2. At the time, the air outlet 11 of the refrigeration equipment corresponding to each battery cluster 3 is communicated with the air inlet 21 of the cold air duct corresponding to the battery cluster 3 . Of course, two battery clusters 3 can also share one cooling device 1. In this case, a shunt device needs to be connected to the air outlet 11 of the cooling device, so that the cold air of the cooling device 1 can be distributed to the cold air corresponding to the two battery clusters 3. in pipeline 2. Specifically, the shunt device may include one air inlet and two air outlets, the air inlet of the shunt device is connected to the air outlet 11 of the refrigeration device, and the two air outlets of the shunt device are respectively connected with the cold air corresponding to the two battery clusters 3 The air inlet 21 of the duct is communicated.

The cold air duct 2 can transmit the cold air from the refrigeration equipment 1 to each battery cluster 3, one end of which is communicated with the refrigeration equipment, and the other end is a closed end. Specifically, the cold air duct 2 may be arranged above a row of battery clusters 3 , and a plurality of ventilation openings 21 may be provided on the cold air duct 2 at intervals along the length direction of the cold air duct 2 . The cold air in the cold air duct 2 flows through the ventilation When the port 22 is opened, the flow can be branched from the ventilation port 22 to flow above the battery cluster 3 , and the battery cluster 3 can be cooled by continuing to flow downward. As for the location of the vent 22, when the cold air duct 2 is arranged above the battery cluster 3, the vent 22 can be arranged on the bottom wall of the cold air duct 2 as shown in FIG. The cold air is better in contact with the battery cluster 3. Of course, the vent 22 can also be arranged on the side wall of the cold air duct 2, and the cold air can also flow out from the cold air duct 2 to cool the battery cluster 3. In addition, the cold air duct 2 can also be arranged on the side of the battery cluster 3. The transformations all fall within the protection scope of the present invention.

In addition, optionally, the cross section of the cold air duct 2 can be kept unchanged, so that the cold air duct can be easily processed. Of course, the section of the cold air duct 2 may also be a structure in which the section gradually decreases from the upstream side to the downstream side of the cold air duct 2 , which is more conducive to the diversion of the cold air on the upstream side from the vent 21 . In addition, the present invention does not limit the cross-sectional shape of the cold air duct 2, which can be circular, square, or rectangular.

In addition, in this embodiment, an air baffle 23 is provided on the inner wall of the cold air duct 2 , the plate surface direction of the air baffle 23 has an included angle with the length direction of the cold air duct 2 , and the air baffle 23 is connected to a plurality of ventilation At least one of the ports corresponds to a vent located on the upstream side or the midstream side of the cold air flow in the cold air duct. Correspondence between the wind deflector and the vent here specifically means that the wind deflector and the vent are staggered in the circumferential direction of the cold air duct, and at least one cross section of the cold air duct has both the wind deflector and the vent. For example, the wind deflector and the vent can be disposed opposite to each other, and the projection of the wind deflector and the vent on a plane passing through the length direction of the cold air duct has an overlapping portion. 2 is a schematic structural diagram of an air duct in an energy storage container provided by an embodiment of the present utility model, and FIG. 3 is a top view of an air duct in an energy storage container provided by an embodiment of the present utility model. As shown in FIGS. 2 and 3 , the letter “L” represents The angle between the length direction of the cold air duct 2, the plate surface direction of the wind deflector 23 and the length direction of the cold air duct 2 is, for example, the angle α shown in FIG. The angle of the top wall. The angle range of the included angle α here is preferably 60°˜80°. Specifically, as shown in FIG. 2 , the black arrows represent the flow direction of the cold air, the cold air from the refrigeration equipment 1 flows horizontally in the cold air duct 2 , and the flow direction of the cold air reaching the windshield 23 is at the surface of the windshield. Under the guidance, the flow changes from the original horizontal flow to the flow direction with an angle α with the length direction, and the cold air after changing the flow direction is diverted from the ventilation port 22 and becomes a vertical downward flow direction. Compared with the direct change of the flow direction of the cold air from the horizontal to the vertical downward in the prior art, the flow direction of the present embodiment passes through a transition stage of downward deflection before the flow direction changes from the horizontal to the vertical, so that the cold air is more easily diverted to the ventilation openings. twenty two. Of course, the included angle α here is not limited to an acute angle, but can also be an obtuse angle, so that the degree of deflection of the cold air can be deeper, and the steering effect of the cold air can be better.

In the cold air duct, the ventilation openings 22 can be arranged at different positions in the cooling air duct 2. Optionally, a part of the ventilation openings 22 are arranged in the position corresponding to the upstream side of the cold air flow in the cooling air duct 2, and a part of the ventilation openings 22 are arranged in the cooling air duct 2. In the cold air duct 2 at a position corresponding to the midstream side where the cold air flows, a part of the vents 22 are provided in the cold air duct 2 at a position corresponding to the downstream side where the cold air flows. While the air baffle 23 corresponds to at least one vent 22 located on the upstream side or the midstream side of the cold air flow in the cold air duct among the vents 22, specifically, the air baffle 23 corresponds to at least one vent 22 located on the upstream side, Either the wind deflector 23 corresponds to at least one vent 22 on the midstream side, or the wind deflector 23 corresponds to at least one vent 22 on the upstream side and at least one vent 22 on the downstream side. When the wind deflector 23 corresponds to at least one vent 22 on the upstream side, the wind deflector 23 partially changes the flow direction of the cold air flowing through the vent 22 on the upstream side, so that the flow direction of the cold air is deflected downward, so that the The cold air is more likely to flow into the battery cluster 3 located on the upstream side through the vent 22, so that the cooling of the battery cluster 3 corresponding to the upstream side of the cold air duct can be improved. The case where the wind deflector 23 is arranged in the midstream, or in both the midstream and the downstream is similar, and will not be repeated here. In addition, optionally, the width of the air baffle 23 in the cross-sectional direction of the cold air duct is the same as the width of the cold air duct, and the protruding length of the air baffle 23 from the inner wall of the cold air duct is smaller than the height of the cold air duct, that is, the air baffle 23 A certain distance should be maintained between the free end of the duct and the inner wall of the cold air duct 2 to allow the cold air to flow through.

Next, the correspondence between the wind deflector 23 and the vent 22 will be described. Optionally, there are a plurality of air baffles 23 and are arranged at intervals along the length direction of the cold air duct 2 . The air baffles 23 include first air baffles 231 . The edge on the upstream side is set accordingly. By arranging the first wind deflector 231 to correspond to the upstream end of the vent 22, that is, the upstream side edge, the first wind deflector 231 can change the flow direction of the cold air just after flowing through the upstream end of the vent 22. , and divert the flow to the corresponding vent 22 to the greatest extent. It has been verified by experiments that at this time, the vent 22 corresponding to the first wind baffle 231 can obtain a relatively large amount of cold air. However, in the case of a large number of ventilation openings 22, if each ventilation opening 22 is correspondingly provided with the first air baffle 231, it will undoubtedly increase the processing difficulty and production cost of the cold air duct 2. Therefore, multiple ventilation openings 22 can be considered. The ventilation openings share one air baffle 23 . Specifically, optionally, every two ventilation openings 22 corresponds to a first air baffle 231 , that is, there is one ventilation opening 22 between the ventilation openings corresponding to the first air baffle 231 . In the example shown in FIG. 2 , each windshield is a first windshield 231 , and each first windshield 231 is spaced apart by a second preset distance, wherein the second preset distance is two rows of batteries The sum of the widths of the clusters. The first wind deflector 231 on the most upstream side is provided at a position corresponding to the left end portion of the vent port 22 on the most upstream side. Of course, the present invention is not limited to this. Among the plurality of wind deflectors 23, the number of the first wind deflectors 231 can be set according to actual needs. In addition, the spacing between the wind deflectors can also be other.

In addition, when cold air flows in the cold air duct 2, the flow velocity gradually becomes slower from the upstream side to the downstream side, and the momentum gradually becomes smaller, so it is more difficult for the cold air to flow out from the vent on the downstream side than from the vent on the upstream side. , this will result in the uneven amount of cold air flowing out from each vent 22. In order to avoid this, from the upstream side to the downstream side of the cold air flow in the cold air duct 2, a plurality of air baffles 23 and the cold air duct 2 can be connected. The included angle α between the length directions of the ducts increases gradually, and/or the protruding length of the plurality of wind deflectors 23 relative to the inner wall of the cold air duct 2 increases gradually. In this way, the guiding degree of the cold air can be gradually increased from the upstream to the downstream side, and the amount of the cold air branched out from each vent 22 can be the same, which is beneficial to the uniform cooling of each battery cluster 3 .

In addition, as described above, the plurality of battery clusters 3 in the battery chamber 42 may be arranged in an array. When there are multiple cold air ducts 2, each cold air duct 2 is correspondingly arranged above a row of battery clusters 3, and is located in the same cold air The ventilation openings 22 on the duct 2 are arranged in a one-to-one correspondence with the battery clusters 3 located directly below the same cold air duct 2 . In other words, the number of cold air ducts 2 can be the same as the number of columns arranged in the array of battery clusters 3 , and a cold air duct 2 is correspondingly arranged above each row of battery clusters 3 . The number of the battery clusters 3 can be the same as the number of the battery clusters 3 included in each column, and is set in a one-to-one correspondence with each battery cluster 3 , so that each battery cluster 3 can be well cooled respectively.

Each battery cluster 3 may include a plurality of stacked battery boxes 31, the battery box 31 accommodates batteries inside, the battery box 31 includes a battery box air inlet, and the plurality of batteries included in the battery cluster 3 located under the same cold air duct The battery box air inlets of the box 31 are oriented in the same direction, and the cold air duct 2 is arranged close to the side where the battery box air inlet is located. Specifically, each battery cluster 3 may further include a battery rack 32, and the battery rack 32 is used for stacking a plurality of battery boxes 31 in a vertical direction. The battery box 31 generally includes a battery box air inlet and a battery box air outlet. The cold air flowing out from the vent 22 flows into the battery box air inlet to cool the cells in the battery box 31, and the hot air heated by heat exchange flows out of the battery box. The air outlet flows out. Therefore, in order to facilitate the flow of cold air into the above-mentioned air inlet of the battery box, the location of the cold air duct 2 may be close to the side where the air inlet of the battery box is located. Of course, in order to make the cooling effect better, the vent 22 can also be set close to the side where the air inlet of the battery box is located on the cold air duct 2. Specifically, as shown in FIG. 3, the vent 22 can be set close to the battery box. The side where the air intake is located.

In addition, optionally, a separator 5 is further provided between the battery clusters 3 adjacent to each other in the same row, the top of the separator 5 extends to the lower surface of the cold air duct 2, and the bottom end of the separator 5 is The height direction of the box body extends downward. As shown in FIGS. 1 and 2 , the separator 5 can further guide the cold air branched out from the vent 22 , so that the cold air can flow from top to bottom along the battery cluster 3 better. Of course, it is preferable to extend the separator 5 to the bottom wall of the container, so that the cold air can more easily reach the battery boxes 31 located at the bottom of the battery cluster 3, so that the battery boxes 31 at all heights can be better cooled. In addition, it is preferable that the width of the separators 5 in the row direction in which the battery clusters 3 are arrayed is larger than the width of each battery cluster 3 in the row direction.

In addition, optionally, a corner portion 24 is provided at the position of the cold air duct 2 close to the air inlet 11 of the cold air duct, and a turning partition 25 is provided on the inner wall of the corner portion 24. There is an included angle between the directions of the airflows, and the included angle can be any angle greater than zero.

FIG. 4 is a schematic structural diagram of an energy storage container provided by an embodiment of the present invention. As shown in FIG. 4 , since the refrigeration equipment 1 is arranged on the side of the battery cluster 3 , the air outlet 11 of the refrigeration equipment generally faces upwards. 2. The corner portion 24 is generally provided at the position close to the air inlet 11 of the cold air duct, and when the cold air enters the air inlet 21 of the cold air duct from the air outlet 11 of the refrigeration equipment, energy loss will occur at the corner portion 24, so that the energy loss occurs at the corner portion 24. The flow velocity is reduced. In order to avoid this situation, a turning baffle 25 having a certain angle with the flow direction of the cold air is generally arranged at the corner portion 24 to buffer and guide the cold air flow. The turning baffle 25 here can be as shown in FIG. 4 , and the included angle with the gas flow direction in the cold air duct 2 is 45°.

Of course, a diverting baffle 25 may also be provided at the rear of the cold air duct 2 , so that the airflow flowing to the rear of the cold air duct passes through the diverting baffle and is more easily branched out from the vent 22 .

The working process of the energy storage container of this embodiment will be described below with reference to FIG. 1 and FIG. 2 . First, the cold air generated by the refrigeration equipment 1 enters the cold air duct 2 through the air inlet 21 of the cold air duct. When it flows through the corner portion 24, it enters the level of the cold air duct 2 with less loss through the diversion effect of the turning baffle 25. Part of it flows horizontally. When passing through the first wind baffle 231 , the flow direction of the cold air is deflected downward along the plate surface of the first wind baffle 231 , and a part of the cold air is split through the ventilation openings 22 corresponding to the first wind baffle 231 . To the corresponding battery cluster 3, another part of the cold air continues to flow along the inside of the cold air duct 2 until it encounters the next first wind baffle 231. Based on the same principle, a part of the cold air passes through the next first wind baffle 231. The corresponding two vents 22 are branched to the corresponding battery clusters 3, and the other part of the cold air continues to flow along the interior of the cold air duct 2, so that when the cold air reaches the rear of the cold air duct 2, the horizontally flowing cold air turns to the baffle at the rear. Under the guidance of 25, the flow is shunted to the corresponding battery cluster 3 through the corresponding ventilation openings 22 of the turning separator. The cold air shunted to the top of the battery cluster 3 flows from top to bottom under the diversion effect of the separator 5 , so that the battery boxes 31 at various heights can be better cooled. The cold air flowing near the battery box 31 flows into the battery box from the battery box air inlet to cool the cells in the battery box 31, and the hot air heated by heat exchange flows out from the battery box air outlet.

In this embodiment, the cooling device 1 can also be selected to have an air inlet of the cooling device, and the hot air flowing out from the air outlet of the battery box can enter the cooling device from the air inlet of the cooling device, so as to realize the cooling cycle in the battery compartment 42 , Of course, the air inlet of the refrigeration equipment may be located on the side of the air outlet of the battery box of the battery cluster 3 .

Corresponding to the two columns of battery clusters 3 shown in FIG. 1 , for each column of battery clusters 3 , the air inlets of each battery box can be directed to the outside of the row direction of battery clusters 3 , and the air outlets of each battery box can be directed to the row of battery clusters 3 . In this way, the air outlet of the battery box can be arranged toward the aisle between the two rows of battery clusters 3 . As long as the air inlet of the refrigeration equipment is arranged in the aisle, the recovery of hot air can be facilitated.

The energy storage container of this embodiment includes refrigeration equipment and cold air pipes. The refrigeration equipment and cold air pipes are arranged inside the box of the energy storage container. The air outlet of the refrigeration equipment is connected with the air inlet of the cold air pipes. The cold air pipes are located along the cold air pipes. There are a plurality of ventilation openings spaced apart in the length direction of the cold air duct, and an air baffle is arranged on the inner wall of the cold air duct. At least one of the air vents corresponds to a vent located on the upstream side or the midstream side of the cold air flow in the cold air duct. The inner wall of the cold air duct is provided with an air baffle having an included angle with the cold air duct, and the air baffle corresponds to at least one of the plurality of vents located on the upstream side or the midstream side of the cold air duct, so when When the cold air from the refrigeration equipment flows along the length direction in the cold air duct, when it flows through the upstream or midstream, it can change its direction locally under the shielding effect of the windshield. The angle between the flow direction of the cold air and the air outlet direction at the vent Compared with the situation where the windshield is not provided in the prior art, it is easier to divert the flow to the vents located in the upstream or midstream, which improves the situation that a large amount of cold air is accumulated in the downstream of the cold air duct in the prior art. The battery cluster corresponding to the upstream or midstream of the cold air duct can also be effectively cooled, so the energy storage container of this embodiment is cooled evenly and has a good cooling effect.
