Description

Technical Field

[0001] The present application relates to the technical field of capacitors, and in particular to an aluminum electrolytic capacitor with a heat dissipation structure. Background Art

[0002] Aluminum electrolytic capacitors, also known as capacitors, are energy storage components. Their structures can be divided into three types: fixed capacitors, semi-variable capacitors, and variable capacitors. They are characterized by large capacity, but large leakage, large errors, and poor stability. Aluminum electrolytic capacitors can be divided into four categories: lead-type aluminum electrolytic capacitors; horn-type aluminum electrolytic capacitors; bolt-type aluminum electrolytic capacitors; and solid-state aluminum electrolytic capacitors.

[0003] The existing solid aluminum electrolytic capacitors do not use electrolyte as the dielectric material inside, but use conductive polymer materials as the dielectric material. When the electronic components are in use, it is inevitable that a high amount of heat will be generated. In order to ensure the normal use of the capacitors, the heat must be dissipated. When the existing capacitors dissipate heat, they only exchange heat between the inner core and the outside air through their outer shell. When in use, the heat dissipation effect is slow and poor.

[0004] Therefore, the present invention proposes an aluminum electrolytic capacitor with a heat dissipation structure to improve the problem. Summary of the invention

[0015] Furthermore, an L-shaped plate is installed on the extension plate, and an inner cavity is opened on the L-shaped plate. A limited rotation plate is slidably installed in the inner cavity through a connecting spring. The limited rotation plate is used to be inserted in the lower outlet.

[0020] The beneficial effects of this application are as follows:

[0021] 1. In the present application, the inner core is installed on a mounting plate, and a mounting shell is installed on the mounting plate. A top hole, an upper air duct and a lower air duct are provided on the mounting shell, so that the inside of the mounting shell is connected with the outside, so that the mounting shell can directly transfer heat while indirectly transferring heat. Moreover, according to the influence of air density, the inner outlet position of the upper air duct located inside the mounting shell is lower than the outer outlet, which is convenient for the discharge of hot air. The upper outlet of the lower air duct is opened in the mounting shell, and the lower outlet is opened outside the mounting shell, which is convenient for external cold air to enter the mounting shell, further facilitating air exchange inside and outside the mounting shell, thereby increasing the heat dissipation effect of the device.

When the mounting shell protects the inner core, this end of the connecting tube is located inside the mounting shell. When the temperature inside the device is too high, the internal temperature is transmitted to the inside of the connecting tube through the graphite sheet, causing the expanding gas to expand, causing the gas to push the push rod, and then driving the movable plate to slide through the push rod, so that the movable plate drives the copper column away from the pin, disconnecting the entire path, and the device automatically breaks the circuit when the temperature is too high, reducing the possibility of the entire circuit failing when the device fails at high temperature, thereby increasing the safety of the device.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0036] Embodiment 1

[0037] like Figure 1 - Fig. 9 As shown, an aluminum electrolytic capacitor with a heat dissipation structure proposed in the first embodiment of the present application includes:

[0038] A mounting board 1 is provided with an inner core 101, and a pin 102 is provided on the inner core 101. The inner core 101 is the inner core of an existing capacitor, and is made of a semiconductor material, such as a conductive material such as capacitor paper, and the pin 102 is a conductor. When in use, the pin 102 is used to connect the capacitor to a circuit board;

[0039] The mounting shell 2 is mounted on the mounting plate 1. The mounting shell 2 is used to accommodate the inner core 101. The mounting shell 2 is provided with a lower air duct 3 and an upper air duct 4. The lower air duct 3 includes a lower outlet 301, a connecting channel 302 and an upper outlet 303 which are interconnected. The connecting channel 302 is obliquely opened on the mounting shell 2. The lower outlet 301 is connected to the outside, and the upper outlet 303 is connected to the inside of the mounting shell 2. The lower air duct 3 is located below the upper air duct 4, and the upper outlet 303 is located above the lower outlet 301. Since the density of air is affected by the temperature, the density of cold air is relatively large and is located below. When the cold air flows, it enters the interior of the mounting shell 2 from the lower outlet 301. When the cold air enters the mounting shell 2 from the upper outlet 303 through the guidance of the connecting channel 302, it is located near the middle of the inner core 101, which is convenient for heat dissipation of the inner core 101.

[0040] The upper air duct 4 includes an inner outlet 401, an air guide duct 402 and an outer outlet 403 which are interconnected. The air guide duct 402 is obliquely opened on the mounting shell 2. The position of the inner outlet 401 is lower than the outer outlet 403. The inner outlet 401 is connected to the inside of the mounting shell 2, and the outer outlet 403 is connected to the outside. Since the density of hot air is low, the hot air inside the mounting shell 2 moves to the outside from the inner outlet 401. The hot air is guided by the air guide duct 402 so that the hot air is discharged from the outer outlet 403 and is blown by the air flow blown out of the lower air duct 3, so that the hot air can be better discharged from the upper air duct 4, thereby improving the air exchange efficiency between the inside and outside of the mounting shell 2, thereby increasing the heat dissipation effect of the capacitor;

[0041] The top hole 5 is opened on the mounting shell 2, a connecting rod 6 is installed on the mounting shell 2, and a shielding cover 7 is installed on the connecting rod 6, so that there is a distance between the shielding cover 7 and the outside of the mounting shell 2, and the projection of the shielding cover 7 on the mounting shell 2 coincides with the top hole 5, and the hot air located at the top of the inner wall of the mounting shell 2 can also be directly discharged through the top hole 5, further increasing the heat dissipation effect of the capacitor, and the shielding cover 7 is installed through the connecting rod 6 when in use, and the top hole 5 is protected by the shielding cover 7, which reduces the influence of the shielding cover 7 on ventilation, and also reduces the possibility of damage to the internal core 101;

[0042] Compared with the prior art, the inner core 101 is installed on the mounting plate 1, and the mounting shell 2 is installed on the mounting plate 1. The mounting shell 2 is provided with a top hole 5, an upper air duct 4 and a lower air duct 3, so that the inside of the mounting shell 2 is connected with the outside, so that the mounting shell 2 can directly transfer heat while indirectly transferring heat, and according to the influence of air density, the inner outlet 401 of the upper air duct 4 located inside the mounting shell 2 is lower than the outer outlet 403, which is convenient for the discharge of hot air, and the upper outlet 303 of the lower air duct 3 is opened in the mounting shell 2, and the lower outlet 301 is opened outside the mounting shell 2, which is convenient for external cold air to enter the mounting shell 2, further facilitating air exchange inside and outside the mounting shell 2, thereby increasing the heat dissipation effect of the device.

[0043] Embodiment 2

[0044] like Figure 7 As shown, the second embodiment further discloses the mounting plate 1 and the mounting shell 2 on the basis of the first embodiment. In the second embodiment, a horizontal plate 201 is provided on the mounting shell 2, and an inclined plate 202 is installed on the horizontal plate 201. The highest end of the inclined plate 202 is connected to the horizontal plate 201, and the lowest end of the inclined plate 202 is spaced apart from the outside of the mounting shell 2. The projection of the inclined plate 202 on the surface of the mounting shell 2 coincides with the external outlet 403. When in use, the distance between the inclined plate 202 and the mounting shell 2 is pulled apart by the horizontal plate 201, and the air discharged from the external outlet 403 is guided by the inclined plate 202.

[0045] The inclined plate 202 has the following advantages when in use. First, when in use, the air discharged from the external outlet 403 is guided so that the hot air is discharged downward and mixed with the cold air outside, thereby reducing the temperature difference between the air around the device and the temperature of the device itself, and reducing the possibility of damage to the device. Second, the external outlet 403 is blocked obliquely above by the inclined plate 202, thereby reducing the possibility of external hot air located above entering the installation shell 2 from the external outlet 403, thereby increasing the practicality of the device.

[0046] like Figure 2 and Figure 8 As shown, in the second embodiment, an extension plate 8 is rotatably mounted on the mounting plate 1, an insert plate 9 is mounted on the extension plate 8, a ring block 10 is mounted on the side wall of the mounting shell 2, an arc groove 11 for accommodating the insert plate 9 is opened on the ring block 10, the groove width of the arc groove 11 is greater than the thickness of the insert plate 9, a protrusion 12 is mounted in the arc groove 11, and a protruding plate 13 is mounted on the insert plate 9. When the protruding plate 13 contacts the protruding plate 12, the separation tendency between the mounting plate 1 and the mounting shell 2 is restricted. The protruding plate 13 is mounted on the insert plate 9 to form an L-shaped structure;

[0047] When in use, the mounting shell 2 is inserted into the mounting plate 1. At this time, the plug-in plate 9 is inserted into the side of the arc groove 11 where the protrusion 12 is not installed. After the insertion is completed, the extension plate 8 is rotated to make the plug-in plate 9 slide in the arc groove 11 and slide to the protrusion 12. At this time, the protruding plate 13 covers the protrusion 12, and the protruding plate 13 is blocked by the protrusion 12, so that the tendency of the mounting shell 2 and the mounting plate 1 to move away from each other is restricted. The mounting shell 2 and the mounting plate 1 are set to be detachably connected, which is convenient for separate production and assembly of the device when leaving the factory, thereby increasing the feasibility of the device.

[0048] like Figure 4 and Figure 5 As shown, in the second embodiment, the mounting plate 1 includes a base plate 103, a movable plate 104 and a connecting plate 105, the extension plate 8 is rotatably mounted on the connecting plate 105, the movable plate 104 is slidably matched with the base plate 103, a plate body is mounted on the extension plate 8, the plate body is L-shaped, and a ring-shaped groove body is provided on the base plate 103, the plate body and the groove body are slidably matched, so that the distance between the connecting plate 105 and the base plate 103 can remain unchanged, and the movable plate 104 is slidably matched with the base plate 103, and the relative distance between the two can still be changed;

[0049] An extension leg 107 is installed on the connecting plate 105, and a copper pillar 106 is installed on the movable plate 104. A sliding hole 109 is provided on the extension leg 107 to slide with the copper pillar 106. A hole 108 is provided on the base plate 103 for the pin 102 to pass through, so that the copper pillar 106 contacts the pin 102. The extension leg 107 is used to connect with the circuit board. When the device is in use, the pin 102, the copper pillar 106 and the extension leg 107 can form a passage connecting the inner core 101 with the circuit board, so that the device can be used normally. The side wall of the copper pillar 106 fits with the inner wall of the sliding hole 109, so that the passage between the extension leg 107 and the copper pillar 106 can still be connected. The copper pillar 106 and the sliding hole 109 are tightly matched, so that the movable plate 104 cannot slide relative to the base plate 103 by gravity alone. When the movable plate 104 slides in a direction away from the base plate 103, the copper pillar 106 is accommodated by the sliding hole 109.

[0050] A connecting tube 1010 is installed on the substrate 103. The connecting tube 1010 is filled with expansion gas, which is carbon dioxide or other gas with a high thermal expansion coefficient. A push rod 1011 is slidably installed in the connecting tube 1010. The push rod 1011 contacts the movable plate 104. The push rod 1011 penetrates the substrate 103 and is connected to the movable plate 104. One end of the connecting tube 1010 is used for sliding connection with the push rod 1011, and the other end is in a sealed state, and a graphite sheet is installed at the end. When the shell 2 is installed to protect the inner core 101, the connecting tube 1010 is This end of 10 is located inside the mounting shell 2. When the temperature inside the device is too high, the internal temperature is transmitted to the inside of the connecting tube 1010 through the graphite sheet, causing the expanding gas to expand, causing the gas to push the push rod 1011, and then the push rod 1011 drives the movable plate 104 to slide, so that the movable plate 104 drives the copper column 106 away from the pin 102, so that the entire path is disconnected, and the device automatically breaks the circuit when the temperature is too high, reducing the possibility of the entire circuit failing when the device fails at high temperature, thereby increasing the safety of the device.

[0051] like Figure 6 As shown, in the second embodiment, a contact plate 20 is installed on the plug board 9, and the inner wall of the contact plate 20 contacts the outer wall of the mounting shell 2. A plurality of annular grooves 21 are provided on the contact plate 20. When in use, the plug board 9 contacts the mounting shell 2 through the contact plate 20, so that the contact plate 20 can transfer heat with the mounting shell 2, and the surface area of ​​the contact plate 20 is increased by the annular grooves 21, thereby increasing the surface area of ​​the mounting shell 2 in contact with the outside air in disguised form, thereby improving the heat dissipation efficiency of the device, and then increasing the heat dissipation effect of the mounting shell 2 when in use.

[0052] like Figure 6 and Fig. 9 As shown, in the second embodiment, an L-shaped plate 22 is installed on the extension plate 8, and an inner cavity 23 is opened on the L-shaped plate 22. A limited rotation plate 15 is slidably installed in the inner cavity 23 through a connecting spring 14. The side wall of the limited rotation plate 15 contacts the inner wall of the inner cavity 23. When in use, the limited rotation plate 15 can only slide along a straight path in the inner cavity 23, which increases the stability of the limited rotation plate 15 when sliding, and also limits the deformation direction of the connecting spring 14, thereby increasing the stability of the connecting spring 14 when deforming;

[0053] When the locking cam 15 is in the locked state, the locking cam 15 is in the locked state, and the locking cam 15 is in the locked state.

[0054] Embodiment 3

[0055] like Figure 1 - Fig. 9 As shown, the third embodiment further discloses the present application on the basis of the second embodiment. In the third embodiment, a plurality of surface extension grooves 16 are provided in the mounting shell 2, and the surface extension grooves 16 are connected with the upper outlet 303 and the inner outlet 401. When in use, the surface extension grooves 16 increase the contact area between the air inside the mounting shell 2 and the mounting shell 2, thereby improving the efficiency of heat exchange of the mounting shell 2, and the opening size of the upper outlet 303 and the inner outlet 401 is also increased through the surface extension grooves 16, thereby further increasing the contact area between the two and the air, thereby further increasing the heat dissipation effect of the device.

[0056] In the third embodiment, a contact block 17 is installed on the plug board 9, and the plug board 9, the contact block 17 and the contact plate 20 are all hollow structures. When in use, the actual thickness of the contact block 17, the plug board 9 and the contact plate 20 is reduced by making the three of them hollow structures, so that the heat on the three can be dissipated faster, thereby increasing the practicality of the device.

[0057] In the third embodiment, a protective shell 18 is installed on the ring block 10, and the length of the protective shell 18 is greater than or equal to the distance between the ring block 10 and the connecting plate 105. When in use, the structure between the ring block 10 and the connecting plate 105 is protected by the protective shell 18, thereby increasing the service life of the device. In addition, the outer wall of the protective shell 18 is used to shield the corners of the outside of the device caused by various components from the user, making the device easy to pick up when in use.

[0058] In embodiment three, a plurality of long grooves 19 are provided on the surface of the protective shell 18. When in use, the long grooves 19 increase the contact area between the protective shell 18 and the outside air, thereby improving the heat dissipation effect of the protective shell 18. The inner diameter of the protective shell 18 is larger than the outer diameter of the mounting shell 2, and there is also a distance between the protective shell 18 and the connecting plate 105, so that the interior of the protective shell 18 can be connected with the outside through various gaps. When in use, the influence on the heat dissipation inside the protective shell 18 is reduced.
