Description

Technical Field

[0001] The utility model relates to the technical field of capacitors, in particular to a high-efficiency heat dissipation capacitor. Background Art

[0002] A capacitor is two conductors placed close to each other with a non-conductive insulating medium in between. When a voltage is applied between the two plates of a capacitor, the capacitor will store charge. The capacitance of a capacitor is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates. The basic unit of capacitance of a capacitor is farad.

[0016] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0017] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0018] like Figure 1 to Figure 2As shown, a specific embodiment of the utility model provides a high-efficiency heat dissipation capacitor, which has a good heat dissipation effect, thereby improving the safety of the capacitor; it includes a capacitor core module 100 and a capacitor shell 200 arranged inside and outside, and the upper end of the capacitor shell 200 is provided with an assembly port 210 for assembling the capacitor core module 100, and the upper end of the capacitor core module 100 is electrically connected to a capacitor busbar 300, and the opening position of the assembly port 210 is arranged in parallel with a plurality of metal heat dissipation plates 400 in surface contact with the capacitor busbar 300, and the surface of the metal heat dissipation plate 400 in surface contact with the capacitor busbar 300 is provided with an insulating layer 500.

[0019] like Figure 1 to Figure 2 As shown, through the above arrangement, the capacitor core module 100 in this embodiment is assembled through the capacitor housing 200. During assembly, the capacitor core module 100 is inserted into the assembly port 210 from top to bottom. Since the connection area between the upper end of the capacitor core module 100 and the capacitor busbar 300 will generate a large amount of heat during the use of the capacitor, the connection end of the capacitor core module 100 and the capacitor busbar 300 in this embodiment is used to dissipate the heat of the heating area of ​​the capacitor by arranging a metal heat sink 400 to prevent heat accumulation at a certain point on the capacitor busbar end, which can effectively improve the heat dissipation effect of the capacitor. At the same time, the insulating layer 500 between the metal heat sink 400 and the capacitor busbar 300 plays an insulating role in the heat dissipation structure, thereby ensuring the safety of the capacitor and improving the overall service life.

[0020] As mentioned above, the metal heat sink 400 needs to be installed at the assembly port 210. In this embodiment, a positioning groove 211 is provided on the side wall of the assembly port 210 corresponding to the end of the metal heat sink 400, and the end of the metal heat sink 400 is inserted into the positioning groove 211. The end of the metal heat sink 400 can be inserted into the positioning groove 211 to stably install the metal heat sink 400. The metal heat sink 400 can also fix the internal capacitor core module 100 to ensure the stability of the entire capacitor structure. In actual applications, the metal heat sink 400 is made of aluminum plate, and the insulating layer 500 is made of insulating paper material. The use of an aluminum heat sink ensures the heat dissipation effect, and the use of insulating paper material has a thinner thickness, which ensures that the heat is dissipated, which is conducive to heat dissipation.

[0021] like Figure 1 to Figure 2 As shown, since the terminals of the capacitor busbar 300 need to be led out from the upper end of the capacitor housing 200, this embodiment provides a terminal block 220 for leading out the capacitor busbar 300 at the upper end of the capacitor housing 200, thereby facilitating the assembly and connection of the capacitor with other equipment.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
