Description

Technical Field

[0001] The utility model belongs to the technical field of battery pack heat dissipation, and particularly relates to an aluminum heat dissipation device. Background Art

[0002] With the rapid development of science and technology, the performance of electronic devices continues to improve, but this is also accompanied by a significant increase in heat generation. Heat dissipation has become one of the key factors restricting the performance improvement of electronic devices. In particular, heat dissipation is a prominent issue in high-power, highly integrated electronic devices such as servers, computers, communications equipment, and battery management systems for new energy vehicles. Aluminum, as a lightweight metal material with excellent thermal conductivity, has been widely used in the field of heat dissipation devices. Aluminum heat sinks not only have excellent heat dissipation performance, but are also relatively low in cost, lightweight, and easy to process and form. In addition, aluminum has good corrosion resistance and can adapt to various complex working environments.

[0003] Currently, traditional battery pack cooling methods mostly rely on natural convection or simple fan cooling, but these methods often have low cooling efficiency and cannot meet the cooling needs of high-power density battery packs. In addition, during the cooling process, the bottom and sides of the battery pack cannot achieve significant heat dissipation effect in the air-cooled cooling mode, which will cause the temperature of local locations of the battery pack to rise, which is not conducive to the long-term use of the battery pack. Utility Model Content

[0004] The purpose of the utility model is to provide an aluminum heat dissipation device to solve the problems of the prior art in that the quilt has heat preservation and positioning functions and is convenient for medical staff to perform transfusion.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An aluminum heat dissipation device includes a base plate, a battery pack placed on the surface of the base plate, a water-cooling heat dissipation group installed on the base plate for cooling the bottom and sides of the battery pack; the water-cooling heat dissipation group includes a water-cooling channel and a cooling plate, the water-cooling channel is installed at the bottom of the base plate, and the cooling plate is vertically installed on the base plate. A liquid inlet and a liquid outlet are respectively provided at both ends of the water-cooling channel; a side plate is provided on one side above the base plate.

[0007] Furthermore, the water cooling channel is laid out in a serpentine pattern beneath the baseplate, divided by a central axis. This serpentine design increases the coolant's flow path within the battery pack, thereby increasing the heat dissipation area and enabling the coolant to more effectively absorb and remove heat generated by the batteries. This design helps improve heat dissipation efficiency, ensuring the battery pack maintains a low temperature during operation, thereby enhancing battery performance and lifespan.

[0008] Furthermore, the battery pack is centered on the central axis of the water cooling channel. This allows the water cooling channel to directly contact the bottom of the battery pack to the greatest extent possible, significantly improving heat transfer from the bottom plate to the battery pack and further enhancing the heat dissipation effect.

[0009] Furthermore, two conducting grooves are provided at the corners of the water cooling channel, and the interior of the cooling plate is connected to the water cooling channel through the conducting grooves. The coolant in the water cooling channel flows into the interior of the cooling plate through the conducting grooves, thereby achieving a heat transfer effect.

[0010] Furthermore, a positioning post is connected between each pair of cooling plates, and a gap is formed between the cooling plates under the support of the positioning post. The gap formed between the cooling plates can help the battery pack dissipate heat better, preventing heat accumulation and battery overheating, thereby protecting battery performance and extending its life.

[0011] Furthermore, the side panels are provided with multiple sets of heat dissipation nets, each set corresponding to the gaps between the cooling plates. A cooling fan is mounted on one side of the side panels. The alignment of the heat dissipation nets with the gaps allows hot air inside the gaps to be expelled through the heat dissipation nets. In conjunction with the cooling fan, the fan can quickly draw the hot air from the gaps to the outside of the device, thereby improving the device's internal heat dissipation.

[0012] The technical solution of this utility model has the following beneficial effects:

[0013] 1. The water-cooling channel is used to dissipate heat from the bottom of the battery pack, effectively absorbing the heat from the bottom of the battery pack. The cooling plate attached to the side wall of the battery pack can effectively absorb the heat from the side wall of the battery pack. The combination of the water-cooling channel and the cooling plate can significantly reduce the operating temperature of the battery pack, effectively improving battery efficiency, ensuring battery safety and extending battery life.

[0014] 2. The correspondence between the heat dissipation net and the gap can help the hot air inside the gap to be discharged from the heat dissipation net. In combination with the heat dissipation fan, the heat dissipation fan can quickly extract the hot air inside the gap to the outside of the device, thereby improving the internal heat dissipation effect of the device. In summary, the simultaneous effects of water cooling and air cooling can greatly accelerate the heat dissipation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1:

[0025] refer to Figure 1 , an aluminum heat dissipation device includes a base plate 10, a battery pack 14 placed on the surface of the base plate 10, and a water-cooling heat dissipation group installed on the base plate 10 for cooling the bottom and sides of the battery pack 14; the water-cooling heat dissipation group includes a water-cooling channel 11 and a cooling plate 15. The water-cooling channel 11 is installed at the bottom of the base plate 10. The water-cooling channel 11 is used to dissipate heat from the bottom of the battery pack 14 and effectively absorb the heat from the bottom of the battery pack 14. A plurality of cooling plates 15 are vertically installed on the base plate 10. The cooling plates 15 are attached to the side walls of the battery pack 14 and can effectively absorb the heat from the side walls of the battery pack 14. In summary, the combination of the water-cooling channel 11 and the cooling plate 15 can significantly reduce the operating temperature of the battery pack 14, effectively improve battery efficiency, ensure battery safety and extend battery life;

[0026] The water-cooling channel 11 has a liquid inlet 12 and a liquid outlet 13 at each end. It is worth noting that the liquid inlet 12 and the liquid outlet 13 are connected to a cooling system that includes a circulating pump. Coolant is pushed by the circulating pump and flows into the battery pack from the liquid inlet 12, flows through the water-cooling channel 11 and the cooling plate 15, absorbs and removes the heat generated by the battery pack 14, and then flows out from the liquid outlet 13, forming a closed loop. After heat dissipation, the coolant temperature drops and returns to the circulating pump, ready to begin the next cycle, thereby ensuring that the battery pack always operates within an appropriate temperature range. The coolant medium is water or other liquid with good thermal conductivity.

[0027] Further references Figure 1 The water-cooling channel 11 is laid in a serpentine shape under the base plate 10. The serpentine flow channel design can increase the flow path length of the coolant in the battery pack, thereby increasing the heat dissipation area, allowing the coolant to more effectively absorb and remove the heat generated by the battery. This design helps to improve heat dissipation efficiency, ensure that the battery pack can maintain a low temperature during operation, and improve the performance and life of the battery. The water-cooling channel 11 is divided by a central axis 21, in which the battery pack 14 is centered on the central axis 21 on the water-cooling channel 11. The battery pack 14 is centered on the central axis 21, which can maximize the direct contact between the water-cooling channel 11 and the bottom of the battery pack 14, greatly improving the heat transfer from the base plate 10 to the battery pack 14, and further improving the heat dissipation effect.

[0028] Further references Figure 3 and Figure 4 Two conducting grooves 16 are provided at the corners of the water-cooling channel 11. The interior of the cooling plate 15 is connected to the water-cooling channel 11 through the conducting grooves 16. The coolant inside the water-cooling channel 11 will enter the interior of the cooling plate 15 from the conducting grooves 16, thereby achieving the effect of heat transfer. The provision of two conducting grooves 16 can be used to simultaneously set up two cooling plates 15. The two cooling plates 15 can simultaneously dissipate heat for the battery packs 14 on both sides. This structural setting avoids a single cooling plate 15 from contacting both sides of the two battery packs 14 at the same time, thereby improving the heat dissipation efficiency. While dissipating heat through the cooling plate 15, the cooling plate 15 can also serve as a positioning function for the installation of the battery pack 14. It is only necessary to align the battery pack 14 with the side of the cooling plate 15, which can facilitate the assembly of the equipment by the staff.

[0029] Embodiment 2;

[0030] refer to Figure 3-Figure 5A positioning column 17 is connected between each two cooling plates 15, and a gap is formed between the cooling plates 15 under the support of the positioning column 17; the positioning column 17 is used to limit the distance between the cooling plates 15, so that the two cooling plates 15 correspond to each other above the two conducting grooves 16, which is conducive to the coolant entering the cooling plates 15, and the gap formed between the cooling plates 15 can help the battery pack 14 to dissipate heat better, preventing heat accumulation from causing overheating of the battery, thereby protecting the performance of the battery and extending its life; the gap can reduce the physical contact between the battery packs 14, reducing the risk of short circuit or adverse interaction between batteries. In the event of an abnormality or failure, this design can reduce the risk of chain reaction inside the battery pack and improve overall safety.

[0031] Further references Figure 2 and Figure 6 A side panel 18 is provided on one side above the base plate 10. Multiple groups of heat dissipation nets 19 are provided on the surface of the side panel 18. Each group of heat dissipation nets 19 corresponds to a gap between the cooling plates 15. A heat dissipation fan 20 is mounted on one side of the side panel 18. The correspondence between the heat dissipation nets 19 and the gaps facilitates the discharge of hot air from within the gaps through the heat dissipation nets 19. Combined with the heat dissipation fan 20, the heat dissipation fan 20 can quickly draw the hot air from the gaps to the outside of the device, thereby improving the device's internal heat dissipation. In summary, the combined effects of water cooling and air cooling can significantly accelerate heat dissipation.

[0032] In Examples 1 and 2, the water-cooled heat dissipation group and the side panels 18 are made of aluminum alloy. Aluminum alloy has good thermal conductivity and can quickly conduct the heat generated by the battery to the external environment, effectively reducing the battery temperature, thereby improving the battery life and safety. The density of aluminum is relatively low, which makes the aluminum heat dissipation shell lighter, helping to reduce the weight of the entire battery pack 14, thereby reducing the vehicle's energy consumption and improving the cruising range of new energy vehicles. At the same time, the aluminum shell also has sufficient strength and rigidity to ensure the safety and stability of the battery pack 14. Aluminum alloy has excellent corrosion resistance and can be used for a long time under various environmental conditions without being easily damaged by oxidation, corrosion, etc., thereby extending the service life of the internal battery pack 14. Aluminum alloy material has good processability and formability, and can meet the complex shape and design requirements of the heat dissipation shell of the battery pack 14, thereby improving production efficiency and reducing costs.

[0033] The specific implementation process of this embodiment is as follows:

[0034] When in use, the water cooling channel 11 is installed at the bottom of the base plate 10. The water cooling channel 11 is used to dissipate heat from the bottom of the battery pack 14 and effectively absorb the heat from the bottom of the battery pack 14. A plurality of cooling plates 15 are vertically installed on the base plate 10. The cooling plates 15 are attached to the side walls of the battery pack 14 and can effectively absorb the heat from the side walls of the battery pack 14. In summary, the combination of the water cooling channel 11 and the cooling plates 15 can significantly reduce the operating temperature of the battery pack 14, effectively improving battery efficiency, ensuring battery safety, and extending battery life.

[0035] Each set of heat dissipation nets 19 corresponds to the gaps between the cooling plates 15, and a heat dissipation fan 20 is installed on one side of the side plate 18. The alignment of the heat dissipation nets 19 with the gaps helps to discharge the hot air inside the gaps through the heat dissipation nets 19. In combination with the heat dissipation fan 20, the heat dissipation fan 20 can quickly draw the hot air inside the gaps out of the device, thereby improving the internal heat dissipation of the device. In summary, the combined effects of water cooling and air cooling can significantly accelerate the heat dissipation effect.
