Description

Technical Field

[0001] This utility model belongs to the field of electric energy storage module technology, specifically relating to a supercapacitor module air-cooled heat dissipation structure. Background Technology

[0002] The supercapacitor modules in data center power supplies are typically long and narrow, such as... Figure 1 As shown. Its cooling method is usually to install a fan at one end of the module to blow air into the module and exhaust air from the other end of the module, so that the heat generated by the power supply can be dissipated through air convection.

[0003] This cooling method has a significant drawback: uneven temperature distribution within the module, with a maximum temperature difference of 15℃-20℃ between the air inlet and outlet. Long-term effects of this temperature difference on the individual capacitors within the power module lead to uneven aging, significant differences in internal resistance, capacitance, and other performance parameters, ultimately shortening the lifespan of the power module.

[0004] In view of this, the present invention provides a supercapacitor module air-cooled heat dissipation structure to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a supercapacitor module air-cooled heat dissipation structure, including an outer shell and a plurality of supercapacitor cells clamped within the shell by a support assembly disposed within the outer shell. A first air duct and a second air duct connecting the supercapacitor cells are formed between the support assembly and the outer shell. An exhaust hole connecting the second air duct is opened on the surface of the outer shell. An air supply device for supplying air into the shell is also provided at both ends of the outer shell. A partition for sealing both ends of the second air duct is provided on the surface of the support assembly, so that external air, driven by the air supply device, passes sequentially through the first air duct, the periphery of the supercapacitor cells, and the second air duct before being discharged from the exhaust hole.

[0006] As a preferred embodiment of the air-cooled heat dissipation structure for a supercapacitor module according to this utility model, the outer shell is a hollow structure with both ends connected.

[0007] As a preferred embodiment of the supercapacitor module air-cooled heat dissipation structure of this utility model, the outer shell includes a top wall and a bottom wall disposed opposite to each other, and opposite side walls connected between the top wall and the bottom wall.

[0008] As a preferred embodiment of the air-cooled heat dissipation structure for a supercapacitor module according to this utility model, the support assembly includes an upper frame connected to the top wall and a lower frame connected to the bottom wall and disposed opposite to the upper frame, with the supercapacitor cell sandwiched between the upper frame and the lower frame.

[0009] As a preferred embodiment of the supercapacitor module air-cooled heat dissipation structure of this utility model, at least a portion of the upper frame and the lower frame are respectively spaced apart from the top wall and the bottom wall to form the first air duct and the second air duct respectively.

[0010] As a preferred embodiment of the air-cooled heat dissipation structure for a supercapacitor module according to this utility model, both the upper frame and the lower frame have through holes on their surfaces for connecting the first air duct, the second air duct, and the supercapacitor cells.

[0011] In a preferred embodiment of the air-cooled heat dissipation structure for a supercapacitor module according to this utility model, the exhaust vent is located on the bottom wall.

[0012] In a preferred embodiment of the supercapacitor module air-cooled heat dissipation structure of this utility model, the partition is disposed at both ends of the lower frame.

[0013] As a preferred embodiment of the supercapacitor module air-cooled heat dissipation structure of this utility model, the upper frame includes a supporting part connected to the top wall, and a mounting part connected between the supporting parts. The mounting part is spaced apart from the top wall, and the through hole is opened on the mounting part.

[0014] The upper frame and the lower frame have the same structure.

[0015] In a preferred embodiment of the air-cooled heat dissipation structure for a supercapacitor module according to this utility model, the air supply device is a cooling fan.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention, through the arrangement of partitions, forces the air supplied into the module via the air supply device to pass through the first air duct, the supercapacitor cells, and the second air duct before being discharged to the outside through the exhaust vent. This allows each supercapacitor cell inside the module to obtain more uniform air convection for heat exchange and cooling, thereby significantly reducing the temperature difference between the supercapacitor cells. Furthermore, because each supercapacitor cell receives better cooling, the overall temperature rise of the module is also significantly reduced. The reduction in module temperature rise and the decrease in temperature difference between cells will improve the performance of the power module and extend its service life.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model relates to a supercapacitor module air-cooled heat dissipation structure, such as Figures 2-4 As shown, it includes an outer casing 1 and several supercapacitor cells clamped inside the casing by a support assembly 3 disposed inside the outer casing 1.

[0027] Among them, such as Figure 3 As shown, the outer casing 1 is a hollow structure with both ends connected. The supercapacitor cells are mounted inside the hollow structure. Air supply devices 2 for supplying air into the casing are located at both ends of the outer casing 1, and exhaust holes 5 are formed on the surface of the outer casing 1. In this embodiment, the air supply device 2 is preferably a cooling fan. When the air supply device 2 is running, it drives external air to enter the interior of the outer casing 1 from both ends, then passes through the gap between the support assembly 3 and the supercapacitor cells, and is discharged through the exhaust holes 5.

[0028] Specifically, such as Figure 4As shown, the outer casing 1 includes a top wall 11 and a bottom wall 12 disposed opposite to each other, and a side wall 13 connecting the top wall 11 and the bottom wall 12. The support assembly 3 includes an upper frame 31 connected to the top wall 11, and a lower frame 32 connected to the bottom wall 12 and disposed opposite to the upper frame 31. The supercapacitor cell is sandwiched between the upper frame 31 and the lower frame 32. Specifically, a protrusion (not marked in the figure) is provided on the inner wall of the clamping point of the supercapacitor cell by the upper frame 31 and the lower frame 32. When the upper frame 31 and the lower frame 32 clamp the supercapacitor cell, the protrusion abuts against the periphery of the supercapacitor cell to clamp and support the supercapacitor cell, so that a certain gap is formed between the periphery of the supercapacitor cell and the upper frame 31 and the lower frame 32. The surfaces of the upper frame 31 and the lower frame 32 are both provided with through holes 6 communicating with the supercapacitor cell.

[0029] In this embodiment, combined with Figure 5 As shown, the exhaust vent 5 is opened on the bottom wall 12, and the upper frame 31 and the lower frame 32 have the same structure. The upper frame 31 includes a supporting part 311 connected to the top wall 11, and a mounting part 312 connected between the supporting parts 311. The mounting part 312 is spaced apart from the top wall 11 to form a first air duct 7 and a second air duct 8, respectively. The through hole 6 is opened on the mounting part 312 and connects to the corresponding first air duct 7. The through hole 6 on the lower frame 32 connects to the corresponding second air duct 8.

[0030] When the air supply device 2 supplies air into the housing, the air will flow through the first air duct 7, the second air duct 8 and the gap between the supercapacitor cell and the upper and lower frames, and finally be discharged from the exhaust hole 5 to carry away the heat and achieve the cooling of the supercapacitor cell.

[0031] Because the second air duct 8 is closer to the exhaust port 5, the airflow will preferentially enter the second air duct 8 and then be discharged from the exhaust port 5 due to the resistance. Only a small portion of the airflow will flow in the gap between the first air duct 7 and the supercapacitor unit and the upper and lower frames, which will affect the heat dissipation of the supercapacitor unit.

[0032] To this end, a partition 4 is further installed at both ends of the lower frame 32 to seal the two ends of the second air duct 8, so that the airflow cannot directly enter the second air duct 8. Instead, the airflow is blocked by the partition 4 and must first enter the first air duct 7, then enter the gap between the supercapacitor cell and the upper and lower frames through the through hole 6, and then enter the second air duct 8, and finally be discharged from the exhaust hole 5.

[0033] By setting up the above, the airflow path is changed, allowing the airflow to pass through the periphery of the supercapacitor cells from top to bottom and then be discharged. This results in each supercapacitor cell inside the module receiving more uniform air convection for heat exchange and cooling, thereby significantly reducing the temperature difference between the supercapacitor cells.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
