Description

Technical Field

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

[0002] Data center power modules are typically long and narrow, with supercapacitors inside arranged in a straight line parallel to their length, forming rectangular air ducts on the top and bottom sides of the supercapacitors. The cooling method usually involves installing a fan at one end of the module to blow air into the module and exhausting the air through an exhaust window at the other end of the module, where the heat generated by the power supply is dissipated through air convection.

[0003] However, the above cooling method has a significant drawback: the air supplied to the module flows through the rectangular air ducts formed on the top and bottom of the supercapacitor, while very little cool air is blown directly onto the surface of the supercapacitor. In addition, the air temperature at the blowing end is also high, which means that the supercapacitor at the end cannot be cooled well. This results in uneven temperature distribution inside the module, with the maximum temperature difference between the air inlet and outlet reaching 15℃-20℃. The long-term effects of this temperature difference on the individual capacitors inside the power module will lead to uneven aging, significant differences in the internal resistance, capacitance and other performance parameters of the individual capacitors, and ultimately a shortened lifespan of the power module.

[0004] In view of this, the present invention provides a slanted air-cooled heat dissipation structure for a supercapacitor module 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 inclined air-cooled heat dissipation structure, comprising: an outer shell, an air supply device and an exhaust device respectively connected to both ends of the outer shell, and a supercapacitor assembly disposed within the outer shell. The supercapacitor assembly extends obliquely along its length within the outer shell to form opposing convection air ducts that gradually recede from the ends of the outer shell towards the interior on the upper and lower sides of the supercapacitor assembly.

[0006] Preferably, the supercapacitor assembly includes a PCB board extending along the length direction of the outer casing, and at least two sets of supercapacitor cells connected to the same surface of the PCB board and spaced apart, wherein the supercapacitor cells are arranged in a straight line forming an angle with the length direction of the outer casing.

[0007] Preferably, the supercapacitor cells are spaced at equal intervals, and the minimum distance between the supercapacitor cells at both ends and the outer casing is equal to the spacing between the supercapacitor cells.

[0008] Preferably, the supercapacitor assembly further includes a bracket disposed opposite to the PCB board for supporting the free end of the supercapacitor cell, and the surface of the bracket is provided with clearance holes adapted to the free end of the supercapacitor cell.

[0009] Preferably, the radial dimension of the clearance hole is larger than the radial dimension of the free end of the supercapacitor cell, and the inner wall of the clearance hole is provided with a protrusion that abuts against the periphery of the free end of the supercapacitor cell.

[0010] Preferably, the clearance holes are interconnected.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes convection air ducts formed on the upper and lower sides of the supercapacitor assembly, which gradually narrow from the end of the outer casing towards the interior. This forces the air blown into the module by the air supply device to be evenly distributed between the individual cells. At the same time, this inclined straight slope design ensures that some cool air can reach the surface of the capacitor cell located at the end of the blowing process, thereby effectively reducing the temperature difference between the beginning and end of the power module and extending the service life of the power module.

[0020] 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.

[0021] Example 1:

[0022] This utility model relates to a slanted air-cooled heat dissipation structure for a supercapacitor module, such as... Figures 1-5 As shown, it includes: an outer shell 1, an air supply device 2 and an exhaust device 3 respectively connected to both ends of the outer shell 1, and a supercapacitor assembly disposed inside the outer shell 1.

[0023] The outer shell 1 includes a top wall 11 and a bottom wall 12 arranged opposite to each other, and a side wall 13 connecting the top wall 11 and the bottom wall 12 to form a hollow structure with both ends connected. In this embodiment, the air supply device 2 is preferably a cooling fan. When the air supply device 2 is running, it can drive the external air to be supplied to the interior of the outer shell 1. The exhaust component 3 is a common exhaust window with evenly distributed exhaust vents on its surface to exhaust the hot air inside the outer shell 1.

[0024] Among them, such as Figure 3 , Figure 5 As shown, the supercapacitor assembly extends in a straight, inclined manner along its length within the housing 1.

[0025] Specifically, such as Figure 3 As shown, the supercapacitor assembly includes a PCB board 14 extending along the length of the outer casing 1, and at least two sets of supercapacitor cells connected to the same surface of the PCB board 14 and spaced apart. The PCB board 14 can be installed on any inner wall surface of the outer casing 1, and the supercapacitor cells are arranged in a straight line forming an angle with the length of the outer casing 1, so that the plane formed by the central axes of all the supercapacitor cells forms a certain angle with the plane containing the top wall 11 or the bottom wall 12 of the outer casing 1. The angle is 0.5°-45°, and the specific angle can be adaptively adjusted according to the actual height of the outer casing 1.

[0026] Combination Figure 5As shown, in this embodiment, the cross-section of the air duct is approximately triangular, with the end facing away from the end of the outer casing 1 forming the apex of the triangle. This creates opposing convection air ducts that gradually narrow from the end of the outer casing 1 towards the interior on the upper and lower sides of the plane formed by the central axes of all the supercapacitor cells. This air duct design forces the air blown into the module by the air supply device 2 to be evenly distributed across the gaps between the capacitor cells. Simultaneously, this inclined straight slope design ensures that some cool air reaches the surface of the capacitor cell at the end of the blowing process, effectively reducing the temperature difference between the beginning and end of the power module and extending its service life.

[0027] Furthermore, to better ensure that the air blown into the module is evenly distributed between the supercapacitor cells, the supercapacitor cells are spaced at equal intervals. The minimum distance between the supercapacitor cells at both ends and the outer casing 1 is equal to the spacing between the supercapacitor cells. In this embodiment, the spacing between the supercapacitor cells is 2mm. This equal spacing forces the air blown into the module to circulate evenly through this spacing, thus achieving better flow uniformity.

[0028] Example 2:

[0029] Based on the above embodiment one, this embodiment also provides a bracket 15 for supporting the free end of a supercapacitor cell, to solve the problem of misalignment between the free end of the supercapacitor cell and the PCB board 14 due to gravity. Figure 4 As shown.

[0030] Specifically, the bracket 15 is positioned opposite to the PCB board 14, and its surface is provided with a clearance hole 16 that is adapted to the free end of the supercapacitor cell, so that after the free end of the supercapacitor cell is inserted into the clearance hole 16, it provides effective support to the periphery of the free end of the supercapacitor cell.

[0031] Furthermore, to prevent the free end of the supercapacitor cell from being unable to effectively contact the cooling air after the clearance hole 16 supports it, the radial dimension of the clearance hole 16 is set larger than the radial dimension of the free end of the supercapacitor cell. This creates a gap between the inner wall of the clearance hole 16 and the free end of the supercapacitor cell. Simultaneously, a protrusion 17 is provided on the inner wall of the clearance hole 16 to abut against the free end of the supercapacitor cell. In this embodiment, the protrusion 17 has a semi-circular cross-section and abuts against the upper and lower circumferences of the free end of the supercapacitor cell. The protrusion 17 and its semi-circular cross-section allow for point contact with the free end of the supercapacitor cell, reducing the support area. Simultaneously, the gap between the inner wall of the clearance hole 16 and the periphery of the supercapacitor cell allows for the flow of cooling air, enabling the cooling air to better act on the surface of the supercapacitor cell and achieve effective cooling and heat dissipation.

[0032] Furthermore, the clearance holes 16 can be connected together, which can further reduce the obstruction of the clearance holes 16 on the periphery of the supercapacitor cell, so as to further allow the cooling air to act on the surface of the supercapacitor cell.

[0033] 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.
