[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fitting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] In addition, it should be noted that in the description of this utility model, the terms and nouns in each embodiment, such as "upper," "lower," "front," and "rear," which indicate the location, are only used to simplify the description of the positional relationship based on the accompanying drawings. They do not mean that the components and devices referred to must be operated in accordance with the specific location and limited operation, method, and structure in the specification. Such directional terms do not constitute a limitation on this utility model.

[0031] This paper establishes an XYZ coordinate system, where the X-axis represents the front-back direction, with the positive direction of the X-axis representing the front and the negative direction representing the rear; the Y-axis represents the left-right direction, with the positive direction of the Y-axis representing the left and the negative direction representing the right; and the Z-axis represents the up-down direction, with the positive direction of the Z-axis representing the up and the negative direction representing the down. It should be noted that the aforementioned X, Y, and Z-axis representations are for ease of description and simplification of this invention, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] like Figures 1-4As shown in the figure, a battery cooling device according to an embodiment of the present invention includes a housing 1 and a heat dissipation and dust blocking assembly 2. The side wall of the housing 1 is provided with a ventilation hole area. The heat dissipation and dust blocking assembly 2 includes a mounting frame 21, a fan 22 and a filter screen 23. The mounting frame 21 is disposed outside the housing 1, located at the ventilation hole area and connected to the housing 1. The fan 22 is installed inside the mounting frame 21. The filter screen 23 is disposed on the side of the mounting frame 21 away from the housing 1 and is detachably connected to the mounting frame 21.

[0033] Specifically, the housing 1 can be a square housing with a hollow interior for storing batteries. Ventilation hole areas are provided on one or more side walls of the housing 1. Each ventilation hole area has multiple ventilation holes, which can be elongated or circular in shape. Heat dissipation and dust protection components 2 are provided corresponding to the ventilation hole areas. The mounting frame 21 of the heat dissipation and dust protection components 2 can be a quadrilateral frame surrounding the corresponding ventilation hole area. It can be fixedly connected to or detachably connected to the side wall of the housing 1. The mounting frame 21 supports the installation of fans 22. One fan 22 can be provided, or two or more can be provided side-by-side, facing the ventilation hole areas. When the fans 22 are powered on and rotate, they accelerate airflow to enter and exit the housing 1 through the ventilation holes.

[0034] The mesh size of filter screen 23 is unlimited and can be flexibly selected according to the filtration level requirements. Filter screen 23 and mounting frame 21 can be detachably connected by bolts, clips, or other means.

[0035] In this embodiment, the battery can be placed inside the housing 1. A ventilation hole area is provided on the housing 1, and a heat dissipation and dustproof assembly 2 is provided on the outside of the housing 1. The mounting frame 21 of the heat dissipation and dustproof assembly 2 is connected to a part of the housing 1 around the ventilation hole area. A fan 22 is installed inside the mounting frame 21 and is opposite to the ventilation hole area. When the fan 22 is started, air outside the housing 1 can be drawn into the housing 1 through the ventilation hole or air inside the housing 1 can be drawn out of the housing 1 through the ventilation hole. During the air flow, the heat around the battery is carried away, thereby achieving heat dissipation and cooling of the battery. Meanwhile, a filter screen 23 is provided on the side of the mounting frame 21 away from the housing 1. The filter screen 23 can effectively block dust in the outside air from entering the housing 1 through the ventilation holes, preventing the battery, fan 22 and other components from being covered by dust and affecting the heat dissipation and cooling effect of the battery. Moreover, the heat dissipation and dust blocking component 2 integrates filtration and heat dissipation, which simplifies the structure compared to the solution where the filter screen and heat dissipation fan are set separately. Since the heat dissipation and dust blocking component 2 is located outside the housing 1, the filter screen 23 of the heat dissipation and dust blocking component 2 is detachably connected to the mounting frame 21, which can facilitate cleaning and replacement of the fan 22 and filter screen 23, further ensuring the heat dissipation and cooling effect of the battery, so that the battery can be kept within a suitable temperature range and extend the battery's service life.

[0036] like Figure 1 and Figure 3 As shown, optionally, the housing 1 includes a first cylindrical body 11, a second cylindrical body 12, and a connecting plate 13. Both the first cylindrical body 11 and the second cylindrical body 12 have open ends. The second cylindrical body 12 is sleeved outside the first cylindrical body 11. The open ends of the second cylindrical body 12 and the open ends of the first cylindrical body 11 are connected through the connecting plate 13. The ventilation hole area includes a first ventilation hole area 111 disposed on the first cylindrical body 11 and a second ventilation hole area 121 disposed on the second cylindrical body 12. The positions of the first ventilation hole area 111 and the second ventilation hole area 121 correspond.

[0037] Specifically, taking the vertical arrangement of the housing 1 as an example, the open end of the first cylinder 11 faces upward, and the open end of the second cylinder 12 faces upward. The first cylinder 11 passes through the open end of the second cylinder 12 to be inserted into the interior of the second cylinder 12. The open ends of the first cylinder 11 and the second cylinder 12 are connected by a connecting plate 13. The first cylinder 11, the second cylinder 12, and the connecting plate 13 form a relatively enclosed receiving space 5 for placing related components, such as the cooling circulation pipe 33 described below, to prevent components from being exposed. The side walls of the first cylinder 11 and the second cylinder 12 together form the side wall of the housing 1. The ventilation hole area on the side wall of the housing 1 is composed of the first ventilation hole area 111 on the first cylinder 11 and the second ventilation hole area 121 on the second cylinder 12. The first ventilation hole area 111 and the second ventilation hole area 121 are corresponding in position, meaning that their ventilation hole areas are at least partially opposite each other.

[0038] The interior of the first cylinder 11 can be used to house batteries. When the fan 22 is working, outside air is blown toward the batteries through the first ventilation hole area 111 and the second ventilation hole area 121. The first ventilation hole area 111 and the second ventilation hole area 121 can be aligned to improve ventilation.

[0039] like Figure 4 As shown, optionally, the mounting frame 21 includes side plates 211 and mounting plates 212. Multiple side plates 211 are connected in sequence to form a frame structure. One end of the frame structure is connected to the housing 1, and the other end of the frame structure is connected to the mounting plate 212. The mounting plate 212 is provided with mounting holes 2121, and the fan 22 is installed in the mounting holes 2121.

[0040] Specifically, the mounting frame 21 may include four side plates 211 and a mounting plate 212. The four side plates 211 are arranged around each other and connected to form a frame structure. One end of the frame structure is connected to the mounting plate 212, and the end of the frame structure away from the mounting plate 212 is connected to a portion of the housing 1 surrounding the ventilation hole area. A suitable number of mounting holes 2121 may be provided on the mounting plate 212. The fan 22 is provided one-to-one with the mounting holes 2121. The mounting holes 2121 may be circular holes that match the outer contour of the fan 22 to facilitate the installation of the fan 22 on the mounting frame 21. The fan 22 does not extend beyond the side surface of the mounting plate 212 away from the frame structure to avoid interference with the filter screen 23.

[0041] Optionally, the orthographic projection of the mounting frame 21 on the side wall of the housing 1 covers the second ventilation hole area 121. That is, the second ventilation hole area 121 is set within the orthographic projection area of ​​the mounting frame 21 on the housing 1, ensuring that the heat dissipation and dust blocking assembly 2 can completely block the second ventilation hole area 121. Outside air can only enter the interior of the second cylinder 12 through the filter screen 23, the mounting hole 2121, and the second ventilation hole area 121, without any other flow path, ensuring that the air entering the housing 1 is filtered and preventing dust from entering.

[0042] Optionally, the filter screen 23 is disposed on the side of the mounting plate 212 away from the frame structure, and the orthographic projection of the filter screen 23 on the mounting plate 212 covers the mounting hole 2121. That is, the mounting hole 2121 is disposed within the orthographic projection area of ​​the filter screen 23 on the mounting plate 212, ensuring that the filter screen 23 can completely block the mounting hole 2121, and dust will not enter the mounting hole 2121.

[0043] like Figure 4 As shown, optionally, the fan 22 includes a fan body 221 and a fan frame 222. The fan frame 222 is installed in the mounting hole 2121. The fan frame 222 is arranged in a ring shape. The fan frame 222 has a through hole 2221 in its circumference. The fan body 221 is installed inside the fan frame 222.

[0044] Specifically, the rotation of the fan body 221 accelerates the flow of surrounding air. The fan frame 222 supports the fan body 221, and the fan frame 222 has multiple through holes 2221 arranged around its circumference. When the fan body 221 is started, air entering from one end of the fan frame 222 can be blown out from the other end of the fan frame 222 and through the through holes 2221, and enter the ventilation hole area. The through holes 2221 arranged around the circumference of the annular fan frame 222 are beneficial to accelerating airflow.

[0045] like Figure 2 and Figure 6 As shown, optionally, the battery cooling device further includes a cooling circulation assembly 3, which includes a coolant storage tank 31, a pump 32, and a cooling circulation pipe 33. The coolant storage tank 31 and the pump 32 are both located outside the housing 1. The pump 32 is connected to the coolant storage tank 31 and the cooling circulation pipe 33 respectively. A receiving space 5 is formed between the outer wall of the first cylinder 11 and the inner wall of the second cylinder 12. The cooling circulation pipe 33 is arranged in the receiving space 5.

[0046] Specifically, the coolant storage tank 31 can store cooling media such as water, and the pump 32 draws the coolant in the coolant storage tank 31 into the cooling circulation pipe 33. The coolant circulates in the cooling circulation pipe 33, which is located in the accommodating space 5 between the first cylinder 11 and the second cylinder 12, thereby achieving heat dissipation and cooling of the battery in the first cylinder 11.

[0047] Optionally, the cooling circulation pipe 33 is arranged inside the side wall of the housing 1 where the ventilation hole area is located. In this way, when air enters and exits the housing 1 through the ventilation hole area, it can better remove the heat in the cooling circulation pipe 33, realize the heat exchange between the cooling circulation pipe 33 and the battery inside the housing 1, and improve the heat dissipation and cooling effect of the battery.

[0048] For example, such as Figure 1 As shown, the housing 1 has ventilation hole areas on two side walls along the Y-axis, and the cooling circulation pipe 33 is arranged in the two side walls of the housing 1.

[0049] Optionally, the longitudinal section of the accommodating space 5 can be U-shaped, and the cooling circulation pipe 33 can include multiple U-shaped pipes 331 arranged in parallel and connected end to end in sequence. The shape of the U-shaped pipe 331 matches the U-shaped longitudinal section shape of the accommodating space 5. That is, the two parallel vertical pipe sections in the U-shaped pipe 331 are located between the side wall of the first cylinder 11 and the side wall of the second cylinder 12, and the bottom section of the U-shaped pipe 331 is located between the bottom wall of the first cylinder 11 and the bottom wall of the second cylinder 12, so that the cooling circulation pipe 33 surrounds the battery in the first cylinder 11, and the battery is cooled more evenly and the cooling effect is better.

[0050] Specifically, as described in the previous embodiment, in order to improve heat exchange efficiency, the two parallel vertical tube sections in the U-shaped tube 331 can be located in the two side walls of the box 1 where the ventilation holes are located.

[0051] like Figure 1 , Figure 2 and Figure 6 As shown, optionally, the cooling circulation assembly 3 further includes an outlet pipe 34, a return pipe 35, and a mounting box 36. The mounting box 36 is installed outside the housing 1. At least one of the outlet pipe 34, the return pipe 35, the coolant storage tank 31, and the pump 32 is located inside the mounting box 36. One end of the cooling circulation pipe 33 is connected to the pump 32 through the outlet pipe 34, and the other end of the cooling circulation pipe 33 is connected to the coolant storage tank 31 through the return pipe 35.

[0052] Specifically, the shapes of the outlet pipe 34 and the return pipe 35 are not limited. A coolant storage tank 31 is located on the front side of the housing 1, that is, on the side of the housing 1 along the positive X-axis. A pump 32 is connected to the top of the coolant storage tank 31; that is, both the coolant storage tank 31 and the pump 32 are located on the front side of the housing 1. Multiple U-shaped tubes 331 of the cooling circulation pipe 33 are arranged side-by-side along the front-back direction of the housing 1, that is, along the X-axis. Specifically, two parallel vertical sections of the U-shaped tubes 331 are located on the left and right sides of the housing 1, respectively. Alternatively, the two ends of the cooling circulation pipe 33, formed by connecting multiple U-shaped tubes 331 end-to-end, are located at the front right and left sides of the housing 1, respectively. To allow the two ends of the cooling circulation pipe 33 to connect with the coolant storage tank 31 and the pump 32 at the front of the housing 1, an outlet pipe 34 is installed between one end of the cooling circulation pipe 33 and the pump 32, and a return pipe 35 is installed between the other end of the cooling circulation pipe 33 and the coolant storage tank 31. For example, the outlet pipe 34 is positioned above the coolant storage tank 31 and can be approximately L-shaped. The return pipe 35 can pass under the housing 1 from the rear, bypassing the bottom of the housing 1 and connecting with the front coolant storage tank 31, thus avoiding interference with the heat dissipation and dust baffle components 2 on the left and right sides of the housing 1. Furthermore, support legs can be installed at the four corners of the bottom of the housing 1 to support the housing 1, leaving a gap at the bottom of the housing 1 to allow the return pipe 35 to pass under the housing 1. Additionally, the outlet pipe 34 and the return pipe 35 are located outside the housing 1 and will not interfere with the cooling circulation pipe 33 inside the housing 1.

[0053] The pump 32 is started to draw the coolant in the coolant storage tank 31 to the outlet pipe 34, and then back to the coolant storage tank 31 through the cooling circulation pipe 33 and the return pipe 35 connected in sequence, so as to realize the cooling cycle of the whole process, so as to continuously and effectively absorb the heat generated by the battery, keep the battery in a suitable temperature range, and extend the battery's service life.

[0054] By setting up the mounting box 36 and placing the external structures such as the outlet pipe 34, return pipe 35, coolant storage tank 31, and pump 32 inside the mounting box 36, the outlet pipe 34, return pipe 35, coolant storage tank 31, and pump 32 can be protected, preventing dust from adhering to them and ensuring cooling effect.

[0055] like Figure 1 As shown, optionally, the housing 1 further includes a cover plate 14, and the connecting plate 13 has an opening 131 at a position corresponding to the cooling circulation pipe 33. The cover plate 14 is closable and covers the opening of the first cylinder 11 and the opening 131.

[0056] In this embodiment, the connecting plate 13 has an opening 131 at a position corresponding to the cooling circulation pipe 33. This opening facilitates the disassembly, repositioning, and maintenance of the cooling circulation pipe 33. For example, when the vehicle is bumpy and the U-shaped tubes 331 of the cooling circulation pipe 33 shake and shift in position, the cooling circulation pipe 33 can be moved through the opening 131 so that the U-shaped tubes 331 can be evenly arranged to dissipate heat evenly from the battery.

[0057] The cover plate 14 matches the shape of the upper surface of the box 1. One end of the cover plate 14 can be hinged to the box 1. After the battery is placed into the first cylinder 11, the cover plate 14 is rotated to cover the open end of the first cylinder 11 and the opening 131, ensuring the cooling effect of the battery and preventing dust from entering the box 1.

[0058] like Figure 1 and Figure 5 As shown, optionally, the battery cooling device further includes a clamping assembly 4, which is located inside the housing 1. The clamping assembly 4 includes a clamping plate 41 and an elastic element 42. The ventilation hole area is provided on one of the opposite side walls of the housing 1, and the other opposite side wall of the housing 1 is connected to the corresponding clamping plate 41 through the elastic element 42. The two clamping plates 41 are arranged opposite each other to clamp the battery.

[0059] In this embodiment, the box 1 has a square structure. One of the opposite side walls of the box 1 is provided with a ventilation hole area, which can form convection and accelerate air flow. Specifically, one of the opposite side walls of the first cylinder 11 is provided with a first ventilation hole area 111, and the other opposite side wall of the first cylinder 11 is provided with a clamping component 4.

[0060] Two clamping plates 41 are provided, and each clamping plate 41 can be connected to the side wall of the first cylindrical body 11 through one or more elastic elements 42. The elastic elements 42 can be compression springs. When the battery is placed between the two clamping plates 41 of the first cylindrical body 11, the clamping plates 41 will compress the elastic elements 42, causing the elastic elements 42 to undergo elastic deformation. The elastic elements 42 have a tendency to restore their deformation, so that the battery can be stably clamped between the two clamping plates 41, avoiding the battery from shaking during vehicle operation and reducing vibration damage to the battery.

[0061] like Figure 5 As shown, optionally, the clamping assembly 4 further includes a damping rod 43, the two ends of which are connected to the clamping plate 41 and the corresponding side wall of the housing 1, respectively, and the elastic element 42 is sleeved on the outside of the damping rod 43.

[0062] In this embodiment, the damping rod 43 is elastic, capable of deforming under load and recovering its deformation after the load is removed. An elastic element 42 is sleeved around the damping rod 43. Both ends of the damping rod 43 are connected to the clamping plate 41 and the housing 1, respectively. When the battery is placed between the two clamping plates 41, the battery presses against the clamping plates 41 to both sides. The elastic element 42 and the damping rod 43 together apply an elastic force to the clamping plates 41, allowing the battery to be stably clamped between the two clamping plates 41, improving the shock absorption effect. Simultaneously, the elastic element 42, sleeved around the damping rod 43, provides compression guidance to the elastic element 42, preventing it from wobbling during deformation and improving the stability of the battery fixation.

[0063] Another embodiment of this utility model provides a power supply device, including a battery and the aforementioned battery cooling device, wherein the battery is placed inside the housing 1 of the battery cooling device. The advantages of this power supply device compared to the prior art are the same as those of the aforementioned battery cooling device, and will not be repeated here.

[0064] Another embodiment of this utility model provides a vehicle including the aforementioned power supply equipment. The advantages of this vehicle compared to the prior art are the same as those of the aforementioned power supply equipment, and will not be repeated here.

[0065] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
