Description

Technical Field

[0001] The utility model relates to the technical field of energy storage devices, in particular to a liquid condensation drainage plate for energy storage, a battery pack, a drainage module and a battery cluster. Background Art

[0002] The integrated liquid cooling box is a very widely used liquid cooling device in the current energy storage industry. When the temperature difference between the temperature generated in the cabin and the surface temperature of the liquid cooling plate is too large during the operation of the battery pack, condensation water droplets will be formed. And because the space inside the battery pack is relatively sealed and the temperature is relatively constant, the temperature difference between the liquid cooling plate and the cabin is more likely to cause the generation of condensation water. The condensation water will mainly concentrate at the bottom of the liquid cooling plate. If the condensation water is not drained in time, the flow of the condensation water is likely to cause faults inside the cabin. Summary of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a liquid condensation drainage plate for energy storage, a battery pack, a drainage module and a battery cluster, which has the advantage of being able to drain the condensation water in time.

And the bottom of any one of the support plates or a group of two relatively arranged support plates is inclined, so that when the drainage plate is installed at the bottom of the liquid cooling plate, the plate body inclines towards one side, and a liquid outlet for discharging the condensation water is arranged on the support plate at the inclined bottom side of the plate body.

[0006] Implementing the above technical scheme, in use, the drainage plate is installed at the bottom of the liquid cooling plate through the connecting ear plates. When condensation water is generated at the bottom of the liquid cooling plate, it will drip onto the plate body and be collected. And because the plate body inclines towards one side, the condensation water will converge towards the liquid outlet and finally be discharged from the liquid outlet, thus avoiding the condensation water flowing into the inside of the battery pack and causing unnecessary faults; the drainage plate of the utility model is simply installed, has a low processing cost, and can effectively drain the condensation water in time.

[0007] In some exemplary embodiments, the bottoms of a group of two relatively arranged support plates are inclined, and a reinforcing step is formed between the support plates and the plate body.

[0010] To implement the above technical solution, it is convenient to connect and fix the drainage plate with the liquid cooling plate.

[0011] In some exemplary embodiments, the connection ear plates are located on both sides of the strengthening step, and the connection holes are located above the strengthening step.

[0012] To implement the above technical solution, the connection ear plates can seal both ends of the strengthening step, further improving the overall structural strength and stability.

[0015] The liquid condensation drainage plate for energy storage as described in the first aspect, the drainage plate is assembled with the liquid cooling plate, and a liquid flow channel is formed between the drainage plate and the liquid cooling plate.

[0016] To implement the above technical solution, by installing the drainage plate at the bottom of the liquid cooling plate, the dripping condensed water can be received and discharged in time through the liquid flow channel, thereby effectively preventing the condensed water from entering the battery pack and causing unnecessary failures.

[0017] In some exemplary embodiments, the liquid cooling plate is placed on the strengthening step, and a strengthening connection area matching the connection ear plate is provided on the side of the liquid cooling plate.

[0018] To implement the above technical solution, it is convenient to connect and fix with the connection ear piece through the strengthening connection area.

[0023] In some exemplary embodiments, the drain branch pipes are arranged obliquely downward.

[0024] Implementing the above technical solution enables the condensed water to flow into the main drain pipe from the drain branch pipes more quickly, improving the drainage speed.

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0038] AsFigure 1 and Figure 2 As shown in Figure 2 , in the first aspect of the embodiment of the present utility model, a liquid-cooled condensation drainage plate for energy storage is provided, including: a plate body 11, support plates 12 are provided around the plate body 11, and connecting ear plates 13 are provided at the corners of the support plates 12. The connecting ear plates 13 are used to be fixedly connected to the liquid-cooled plate 21 provided at the bottom of the battery pack. And the bottom of any one of the support plates 12 or a set of two relatively arranged support plates 12 is inclined, so that when the drainage plate 10 is installed at the bottom of the liquid-cooled plate 21, the plate body 11 is inclined to one side, and a liquid outlet 15 for discharging condensed water is provided on the support plate 12 located at the inclined bottom side of the plate body 11.

[0039] Specifically, in this embodiment, the bottoms of a set of two relatively arranged support plates 12 are inclined, and a reinforcing step 16 is formed between the support plates 12 and the plate body 11. The part of the reinforcing step 16 connected to the support plate 12 is horizontal, and the part of the reinforcing step 16 connected to the plate body 11 is triangular, and its hypotenuse part is connected to the plate body 11; on the one hand, the overall structural strength of the drainage plate 10 can be improved through the reinforcing step 16, and on the other hand, the bottom of the battery pack can be supported by contacting and installing the bottom of the liquid-cooled plate 21 through the reinforcing step 16, and the bottom of the reinforcing step 16 can be placed on the mounting bracket of the battery pack to facilitate the stable placement of the battery pack.

[0040] A connection hole 14 is provided on the connecting ear plate 13. The connection hole 14 is used to pass through a connecting piece to be fixedly connected to the liquid-cooled plate 21, so as to facilitate the connection and fixation of the drainage plate 10 and the liquid-cooled plate 21. The connection hole 14 is a through hole, and the connecting piece usually adopts a screw.

[0041] And in this embodiment, the connecting ear plates 13 are located on both sides of the reinforcing step 16, and the connection holes 14 are located above the reinforcing step 16, so that the connecting ear plates 13 can close both ends of the reinforcing step 16, further improving the overall structural strength and stability.

[0042] During use, the drainage plate 10 is mounted at the bottom of the liquid-cooled plate 21 through the connecting ear plate 13. When condensed water is generated at the bottom of the liquid-cooled plate 21, it will drop on the plate body 11 and be collected. Since the plate body 11 is inclined to one side, the condensed water will converge towards the liquid outlet 15 and finally be discharged from the liquid outlet 15, thus avoiding the condensed water from flowing into the battery pack and causing unnecessary failures; the drainage plate 10 of the present utility model is simple to install, has a low processing cost, and can effectively discharge the condensed water in time.

[0043] such as Figure 3As shown in the figure, the second aspect of the embodiment of the present utility model provides a battery pack, including: a battery pack body 20, a liquid cooling plate 21 is provided at the bottom of the battery pack body 20, and the liquid cooling plate 21 is closely attached to the battery pack body 20 for heat exchange; and, a liquid condensation drainage plate 10 for energy storage as in the first aspect, the drainage plate 10 is assembled with the liquid cooling plate 21, and a liquid flow channel is formed between the drainage plate 10 and the liquid cooling plate 21.

[0044] Among them, the liquid cooling plate 21 is fixed to the bottom of the battery pack by screws. For example, a connecting edge is provided on the outer periphery of the bottom of the battery pack body 20, and a plurality of through holes are evenly opened on the connecting member. The screws pass through the through holes and are threadedly connected with the liquid cooling plate 21, so that the liquid cooling plate 21 is fixed to the bottom of the battery pack body 20, and a water inlet and a water outlet are provided on the liquid cooling plate 21 for connecting with other adjacent liquid cooling plates 21 or circulating equipment for liquid flow cooling medium circulation.

[0045] The liquid cooling plate 21 is placed on the reinforcing step 16, and a reinforcing connection area 22 matching the connecting ear plate 13 is provided on the side of the liquid cooling plate 21. Specifically, threaded holes are opened on the reinforcing connection area 22 for threaded connection with screws. The reinforcing connection area 22 is a solid part on the liquid cooling plate 21, and the opened threaded holes are not communicated with the inside of the liquid cooling plate 21. It is convenient to connect and fix with the connecting ear piece through the reinforcing connection area 22. When the drainage plate 10 is connected to the liquid cooling plate 21, the reinforcing step 16 is attached to the bottom of the liquid cooling plate 21. During installation, the drainage plate 10 can be directly nested outside the liquid cooling plate 21, and the drainage plate 10 is pressed until the reinforcing step 16 is attached to the bottom of the liquid cooling plate 21. At this time, the connection holes 14 on the connecting ear piece are aligned with the threaded holes on the reinforcing connection area 22, and then they can be connected and fixed by screws.

[0046] By installing the drainage plate 10 at the bottom of the liquid cooling plate 21, the dripping condensed water can be received and discharged in time through the liquid flow channel, thereby effectively preventing the condensed water from entering the battery pack and causing unnecessary failures.

[0047] As Figure 4 As shown in the figure, the third aspect of the embodiment of the present utility model provides a drainage module, including: a plurality of liquid condensation drainage plates 10 for energy storage as in the first aspect, and the plurality of drainage plates 10 are evenly arranged in the vertical direction; and, a drain pipe group 30, the drain pipe group 30 includes: a drain main pipe 31, and a plurality of drain branch pipes 32 communicated with the drain main pipe 31. Each drain branch pipe 32 corresponds to each drainage plate 10 one by one and is communicated with the liquid outlet 15. The bottom of the drain main pipe 31 is used for connecting with a waste liquid collection box.

[0048] The number of the drainage plates 10 is consistent with the battery pack to which they are applied, and they are in one-to-one correspondence with the battery pack body 20. Preferably, the drain branch pipes 32 are arranged obliquely downward, so that the condensed water can flow into the drain main pipe 31 from the drain branch pipes 32 more quickly, improving the drainage speed. Of course, in some embodiments, the bottom of the drain main pipe 31 can also be connected to the liquid cooling circulation device, so that the condensed water can be recycled for cooling the battery pack.

[0049] Each drainage plate 10 can receive the condensed water dripping from the bottom of the corresponding battery pack, and then the condensed water can be discharged in time through the liquid outlet 15. After the condensed water converges from the drain branch pipes 32 to the drain main pipe 31, it is collected in the waste liquid collection box for subsequent centralized treatment.

[0050] The third aspect of the embodiment of the present invention provides a battery cluster, including: a drainage module as described in the third aspect; and a plurality of battery pack bodies 20, a liquid cooling plate 21 is provided at the bottom of each battery pack body 20, and each battery pack body 20 is connected to each drainage plate 10 in one-to-one correspondence.

[0051] The connection manner between the battery pack body 20 and the liquid cooling plate 21 is the same as that described in the second aspect, which will not be elaborated here. By adding a drainage module to the battery cluster, the condensed water formed by the liquid cooling plates 21 at the bottoms of the battery pack bodies 20 in the battery cluster can be discharged in time, ensuring the stable operation of the battery cluster.

[0052] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made. These are all equivalent modifications and evolutions made to the above embodiments based on the substantial technology of the present invention, and these all belong to the protection scope of the present invention.
