Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] [Example 1]

[0041] In a specific embodiment, the D1 direction is the first direction, that is, the height direction of the capacitor 2 and the annular radiator 1. The bottom plate 10 is sleeved on the outside of the capacitor 2, which increases the heat dissipation area compared with various previous radiators. A plurality of extremely thin heat sinks 20 are directly connected to the annular bottom plate 10, and the heat sink 20 is arranged on the side of the bottom plate 10 away from the capacitor 2, and extends in the direction away from the capacitor 2 to transfer heat to the outside. The provision of a plurality of heat sinks 20 can further increase the heat dissipation area compared with various previous radiators, thereby improving the heat dissipation efficiency. At the same time, the bottom plate 10 has a good heat conduction effect. The heat dissipation effect of the annular radiator 1 is improved by the bottom plate 10 and the plurality of heat sinks 20, so that the annular radiator 1 can quickly dissipate heat for the capacitor 2. The bottom plate 10 is unfolded into a rectangle, and the bottom plate 10 is provided with two ends, namely a first end and a second end. The bottom plate 10 is bent into a ring by snapping the first end and the second end, so as to facilitate the disassembly and assembly and fixation of the annular radiator 1; and the annular bottom plate 10 is sleeved on the outside of the capacitor 2 to dissipate the heat for the capacitor 2 sleeved in the bottom plate 10.

[0042] Preferably, the annular heat sink 1 is not limited to a circular ring shape, but may also be a rectangular ring shape, so as to adapt to capacitors 2 of different shapes.

[0043] For further information, see Figure 1-Figure 3 The annular heat sink 1 further comprises: a first connecting member 11 and a second connecting member 21, wherein the first connecting member 11 extends from the first end in a direction away from the capacitor 2, and a locking head 110 is provided on the first connecting member 11; the second connecting member 21 extends from the second end in a direction away from the capacitor 2, and a through hole 210 is provided on the second connecting member 21 for cooperating with the locking head 110; wherein, the fixing state of the annular heat sink 1 is changed by adjusting the matching state of the locking head 110 and the through hole 210; when the locking head 110 and the through hole 210 are in a clamping state, the annular heat sink 1 is in a first fixed state.

[0044] Specifically, the heat sink 20 and the first connector 11 and the second connector 21 are arranged in the same manner, and are arranged on the side of the bottom plate 10 away from the capacitor 2, and extend in the direction away from the capacitor 2; the connection state of the first connector 11 and the second connector 21 is changed by the matching state of the lock head 110 and the through hole 210, so that the fixing state of the annular heat sink 1 can be changed; the lock head 110 and the through hole 210 form a snap structure, and when the lock head 110 and the through hole 210 are in the snap-fit ​​state, the first connector 11 and the second connector 21 are connected by the snap-fit ​​structure, and the annular heat sink 1 is in the first fixed state at this time, and the first end and the second end of the annular heat sink 1 are snap-fitted to achieve the fixation of the annular heat sink 1, which is simple and easy to operate; when the annular heat sink 1 is in the first fixed state, a force is applied to release the snap-fit ​​state of the lock head 110 and the through hole 210, release the connection relationship between the first connector 11 and the second connector 21, and thereby release the connection relationship between the first end and the second end.

[0045] Furthermore, the lock head 110 includes: a plurality of snap-fit ​​components 120, the snap-fit ​​components 120 are connected to the first connecting member 11, a deformation groove 123 is formed between the inner walls of the plurality of snap-fit ​​components 120, and the snap-fit ​​components 120 include: a plug-in portion 121 and a limiting portion 122, the plug-in portion 121 is connected to the first connecting member 11; the limiting portion 122 is connected to one end of the plug-in portion 121 away from the first connecting member 11, and the limiting portion 122 is arranged on the outer wall of the plug-in portion 121; wherein, the deformation of the snap-fit ​​component 120 is achieved by applying a force to the snap-fit ​​component 120; when the end of the limiting portion 122 close to the first connecting member 11 abuts against the second connecting member 21, the lock head 110 and the through hole 210 are in a snap-fit ​​state.

[0046] Specifically, the lock head 110 includes a plurality of buckle assemblies 120, and a deformation groove 123 is formed between the inner walls of the plurality of buckle assemblies 120 that are close to each other. The lock head 110 is elastically arranged, and the shape and size of the deformation groove 123 can be changed by applying a force to the buckle assembly 120, thereby changing the shape of the lock head 110 and realizing the deformation of the lock head 110; the plug-in portion 121 and the limiting portion 122 constitute the buckle assembly 120, and the plug-in portion 121 connects the first connecting member 11 and the limiting portion 122, and the limiting portion 122 is inserted into the first connecting member 11. The connecting portion 121 is connected to the first connecting member 11, and the limiting portion 122 is protruding from the outer wall of the plug-in portion 121, and the end of the limiting portion 122 close to the first connecting member 11 is the first abutting portion 1221, and the end of the limiting portion 122 away from the plug-in portion 121 is the second abutting portion 1222. When the first abutting portion 1221 abuts against the through hole 210 on the second connecting member 21, the lock head 110 and the through hole 210 are in a clamping state (can also be expressed as a locking state), and the annular heat sink 1 is in a first fixed state. Preferably, the limiting portion 122 is in the shape of a triangular prism, and the through hole 210 is in the shape of a square.

[0047] Preferably, see Figure 2 The number of the buckle assemblies 120 is two, and the two buckle assemblies 120 are arranged opposite to each other, and the two limiting portions 122 are both protrudingly arranged on the side of the plug-in portion 121 away from the other plug-in portion 121; see Figure 5 This is a partial enlarged view of region B when the annular radiator 1 is not in the first fixed state, see Figure 6 It is a partial enlarged view of region B when the annular radiator 1 is in the first fixed state.

[0048] For further information, see Figure 4-Figure 6 , a first spacing L1 is provided between the outer walls of the limiting portion 122, a second spacing L2 is provided between the outer walls of the plug-in portion 121, the aperture of the through hole 210 is d, L1>L2; wherein, when a first force is applied to the buckle assembly 120, the first spacing and the second spacing gradually decrease; when L1>L2≥d, the lock head 110 is in the first deformation state; when d≥L1>L2, the lock head 110 is in the second deformation state.

[0049] Specifically, since the limiting portion 122 is protruding from the outer wall of the plug-in portion 121, the first spacing is always greater than the second spacing; the direction of the first force is from the outer wall to the inner wall of the buckle assembly 120, and when the first force is applied to the buckle assembly 120, L1 and L2 gradually decrease; when L1>L2≥d, the lock head 110 is in the first deformation state; when the buckle assembly 120 is in a natural state where no force is applied, the buckle assembly 120 is squeezed inward to deform the buckle assembly 120 so that the first spacing L1 is less than or equal to the aperture d of the through hole 210. When L1≤d, that is, when d≥L1>L2, the lock head 110 is in the second deformation state, and the user can adjust the matching state of the lock head 110 and the through hole 210 by changing the deformation state of the lock head 110 according to needs.

[0050] Preferably, in this embodiment, when no force is applied to the buckle assembly 120, L1>L2 and L2=d, at which time the lock head 110 is in the first deformation state; when the first force is applied to the buckle assembly 120 (that is, the buckle assembly 120 is squeezed to the middle to produce deformation), L1>L2 and L1 and L2 gradually decrease until L1<d, at which time the lock head 110 is in the second deformation state, and at the same time, because the through hole 210 is larger than the first spacing, the lock head 110 can move in the through hole 210, and the lock head 110 can pass through the right through hole 210. When the first force disappears, the deformation disappears, and the first abutting portion 1221 abuts against the through hole 210 on the second connecting member 21, thereby achieving snap-on locking. The user can change the fixing state of the annular radiator 1 according to actual needs.

[0051] Furthermore, there are multiple lock heads 110 ; there are multiple through holes 210 , and the multiple through holes 210 are arranged in a one-to-one correspondence with the multiple lock heads 110 .

[0052] Specifically, setting a plurality of locking heads 110 and through holes 210 can improve the connection ability and connection stability of the first connecting member 11 and the second connecting member 21; and the plurality of locking heads 110 correspond one-to-one to the plurality of through holes 210, and the one-to-one setting can also avoid waste of resources. Through the cooperation of the locking heads 110 and the through holes 210, the installation and disassembly of the annular radiator 1 is facilitated.

[0053] Furthermore, the plug-in portion 121 and the limiting portion 122 are integrally formed.

[0054] Specifically, the plug-in portion 121 and the limiting portion 122 are integrally formed, which enhances the firmness of the connection between the plug-in portion 121 and the limiting portion 122 and improves the overall strength of the buckle assembly 120 .

[0055] For further information, see Figure 3 , a plurality of heat sinks 20 are evenly arranged on a side of the bottom plate 10 away from the capacitor 2 .

[0056] For example, evenly disposing the heat sink 20 can improve the uniformity of heat dissipation and avoid overheating of the capacitor 2 due to uneven heat dissipation.

[0057] For further information, see Figure 4 The capacitor 2 has a first height H1 in the first direction, and the bottom plate 10 has a second height H2 in the first direction; wherein H1>H2.

[0058] Specifically, H1 represents the first height, H2 represents the second height, and the height of the annular heat sink 1 in the first direction is smaller than the height of the capacitor 2. When the annular heat sink 1 is sleeved on the outer wall of the capacitor 2, there is room on both the upper and lower sides of the capacitor 2, which facilitates the installation and disassembly of the annular heat sink 1.

[0059] Furthermore, the base plate 10 and the plurality of heat sinks 20 are integrally formed.

[0060] For example, the bottom plate 10 and the plurality of heat sinks 20 are formed by integrated stamping technology, which has a simple manufacturing process and improves the overall strength and firmness of the annular heat sink 1 , making the structure of the annular heat sink 1 more compact.
