Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The heat dissipation air duct provided by the embodiment of the invention is arranged between two adjacent rows of battery racks 20 of the energy storage container, and comprises: an air supply duct case 10; the air supply duct shell 10 encloses an air supply duct, and the structure of the air supply duct shell can be shown in the figures 1-3;
the air supply duct shell 10 is provided with an air duct inlet 11, and the air duct inlet 11 is arranged opposite to an air outlet of the air conditioner 30;
a plurality of air duct air outlets 12 are respectively formed in two sides of the air supply duct shell 10, the air duct air outlets 12 are distributed at intervals along the air flowing direction of the air supply duct shell 10, and the air duct air outlets 12 are arranged opposite to the battery rack 20.
The working principle is as follows: cold air of the air conditioner 30 enters the air supply duct shell 10 from the air supply duct shell 10, and the air duct is filled with the cold air to reach a stable state along with the passage of time; cold air flows to the air inlet of the battery rack 20 from the air outlets 12 of the air ducts respectively and then enters the battery pack from the side surface of the battery pack; and constant amount of cold air flows through the battery pack and then returns to the air return port of the air conditioner 30, so that the heat exchange between the battery core and the air conditioner refrigerant is realized.
According to the technical scheme, the heat dissipation air duct provided by the embodiment of the invention uniformly collects the air outlet of the air conditioner into the air supply duct, so that disordered leakage of cold air is prevented; the collected cold air of the air conditioner is redistributed by arranging a plurality of air outlets matched with the battery rack on the air duct, so that the quantity of the cold air entering the battery pack is ensured to be constant; the temperature equalization of each battery pack is easy to realize, and the temperature equalization of the battery core is further realized. The air duct of the scheme has the air guide effect, so that the existing air supply turbulent fan can be simplified.
There is the gap between battery package and the battery frame, can lead to having partly cold wind not to pass through the battery package, directly flows out from the gap between battery package and the battery frame, leads to leaking outward of cold wind. In view of this, the air outlets 12 of the air ducts are vertically long holes, and the central lines of the air outlets coincide with the vertical central line of the battery rack air inlet 21 of the battery rack 20. Namely, the air duct air outlet 12 and the battery rack air inlet 21 are arranged in an aligned manner and matched in shape, so that cold air of the air conditioner 30 directly enters the battery rack 20, the cold air entering the battery pack is ensured to be constant, the heat dissipation effect is good, and the utilization rate of the cold air is high. The width of the air duct air outlet 12 is smaller than the width of the battery rack air inlet 21 of the battery rack 20, and the air outlet volume of the air duct is the air inlet volume of the battery, so that the air volume of each battery rack is effectively controlled through the design of the air supply duct shell 10, the cold air volume entering the battery pack is ensured to be constant, the temperature equalization of each battery pack is easily realized, and the temperature equalization of the battery cells is further realized.
As shown in fig. 5, the conventional battery rack 20 is generally a square, and the air inlets are formed at the edges, so that the air inlets of two adjacent battery racks 20 on the same side are attached together when they are closely arranged, and for this purpose, the same larger air outlet 12 of the air duct can be used to simplify the structure. In the scheme, the air duct air outlets 12 are vertical strip holes, the central line of each air duct air outlet coincides with the vertical central line between the battery rack air inlets 21 of two adjacent battery racks 20 in the same row, and the width of the air duct air outlet 12 is larger than the width of a single battery rack air inlet 21 and smaller than the sum of the widths of the two battery rack air inlets 21. As shown in fig. 1, the battery racks 20 are divided into two rows of three groups each, each group having six; the six battery racks 20 closely arranged as a group generate five air inlets for attachment, and as shown in fig. 4, the six battery racks correspond to five common air outlets 125 (the width corresponds to two battery rack air inlets 21), and the edge of each group of battery racks 20 corresponds to an independent air outlet 124 (the width corresponds to a single battery rack air inlet 21).
Furthermore, the height of the air outlet 12 of the air duct is matched with the height of the air inlet 21 of the battery rack, so that the heat dissipation requirement of each layer of battery pack is met.
Since the air inlet area of the back plate can be adjusted to be larger, the air inlet amount of the battery pack can be relatively increased.
The air outlet 12 of the air duct is mainly set up in relation to the air speed of the air conditioner and the length of the container, so there are four cases: 1. the wind speed is high and the length is long;
2. the wind speed is high and the length is short;
3. the wind speed is low and the length is long;
4. low wind speed and short length.
For this, three schemes need to be designed:
1. the area of the air outlet 12 of the air duct is changed: large, small, large (suitable for low wind speed and/or long container length scenarios);
2. the area of the air outlet 12 of the air duct is changed: from large to small (suitable for situations with high wind speeds and/or short container lengths);
3. the areas of the air outlets 12 of the air duct are equal, and a baffle is added at the air inlet with small air volume (see the third embodiment of the scheme).
According to foretell first scheme, through the difference of the size of wind channel trompil, the fine control gets into the cold wind volume of every battery package, wherein the general trend law of trompil: the air duct opening close to the most near end of the air conditioner is the largest, the openings of the adjacent air ducts are gradually reduced, then the opening in the middle is constant, and then the opening at the far end is gradually increased so as to ensure the cold quantity at the two ends.
Specifically, along the wind flowing direction of the air duct housing 10, the plurality of air duct outlets 12 at least include: a first outlet 121, a second outlet 122 and a third outlet 123; the structure of which can be seen in fig. 3 and 4;
the area of the first outlet 121 is larger than that of the second outlet 122, and the area of the second outlet 122 is smaller than that of the third outlet 123.
According to the second solution, the area of the plurality of duct outlets 12 gradually decreases along the air flowing direction of the air duct housing 10.
According to the third scheme, the areas of the air outlets 12 of the air ducts are equal;
the heat dissipation wind channel still includes: a baffle 17 disposed in the air duct housing 10, wherein the baffle 17 is perpendicular to the wind flowing direction, and the structure thereof can be seen in fig. 12; by adding the baffle with a certain aperture ratio at the position close to the air outlet of the air conditioner in the air duct, after the cold air at the air outlet of the air conditioner meets the baffle with the aperture, the cold air is gathered between the air conditioner and the aperture baffle due to the resistance effect, and then the local pressure is increased, so that the battery pack close to the air conditioner side obtains more cold air, and further the Bernoulli phenomenon is weakened;
the baffle 17 is provided with a through hole, and the porosity of the upper part is greater than that of the lower part; because the resistance effect, the cold wind volume of bottom in air conditioner and the baffle can partly be extruded to the top, has guaranteed the uniformity of wind speed about the air outlet of air conditioner to increase the cold wind volume of the battery package absorption at top, make the temperature uniformity about the battery cluster better.
The scheme can solve the temperature uniformity of the battery pack in theory, but two problems can exist in the practical process: 1. the cold air flowing out of the air outlet of the air conditioner is not equal in upper and lower speed, so that the sizes of the upper opening and the lower opening of the sealing plate are not consistent, and troubles are brought to production and processing; 2. because the air speed of the air outlet of the air conditioner is high and the eddy phenomenon exists, a large air inlet needs to be formed in the upright post of the battery rack close to the air conditioner, but when the area of the air inlet on the upright post reaches a certain value, the strength of the battery rack cannot be guaranteed.
In view of this, the baffle plate 19 preferably includes: the upper baffle 171, the middle baffle 172 and the lower baffle 173 which are connected in sequence adopt an up-down split structure, and the size change of the opening is realized after the assembly;
specifically, the porosity of the upper baffle 171 is 70%, and the porosities of the middle baffle 172 and the lower baffle 173 are 50%.

Through the installation of the adapter rack 18, the size error is favorably eliminated, and the baffle 19 is accurately assembled; at the same time, stress concentration is avoided when the two side edges of the baffle plate 19 are connected.
Preferably, the air inlet 11 is opened at one end of the air duct housing 10, and the other end of the air duct housing 10 is closed. With the arrangement, all the cold air of the air supply duct shell 10 flows out to the battery rack 20 through the air duct air outlets 12 on the two sides, so that the heat dissipation effect is good, and the utilization rate of the cold air is high; the cold air is filled in the air duct to achieve a stable state, and better temperature uniformity can be achieved.
