Description

Technical Field

[0001] The utility model relates to the technical field of inverters, in particular to an inverter and a heat dissipation structure of its protective shell. Background Art

[0002] An inverter is a converter that converts direct current electrical energy into fixed-frequency and fixed-voltage or frequency-modulated and voltage-regulated alternating current. Inverters are often used in various scenarios, especially in scenarios with a demand for high-power inverters, such as solar power generation, wind power generation, etc. Moreover, for some applications in harsh environments, the heat dissipation requirements for inverters are also very strict. In the existing inverter heat dissipation structure, an active heat dissipation system and a passive heat dissipation system are included; the active heat dissipation system is, for example, a water cooling system or an air cooling system, and these systems all require electrical energy to drive; the passive heat dissipation system usually sets a heat dissipation structure on the inverter housing, such as heat dissipation fins.

[0003] The technical problem that appears in the current design of the inverter housing is that the heat dissipation fins need to cover the surface of the inverter housing to achieve the highest passive heat dissipation efficiency, but in this case, it is impossible to arrange eye-catching logo patterns on the surface of the inverter housing. Summary of the Utility Model

[0004] In view of this, the utility model provides an inverter and a heat dissipation structure of its protective shell, which realizes the setting of eye-catching logo patterns on the surface of the inverter housing while the surface of the inverter housing is covered with heat dissipation fins.

[0005] The utility model provides a heat dissipation structure of a protective shell, including multiple heat dissipation fins arranged on the outer surface of the protective shell housing, and notches are provided on some or all of the heat dissipation fins, and all the notches form a dot matrix pattern of a logo.

[0006] Optionally, the notch penetrates through the opposite two side surfaces of the heat dissipation fin.

[0007] Optionally, the notch includes a flat portion and an arc portion, the flat portion is located at the bottom of the notch, the arc portion is located on both sides of the flat portion along the length direction of the heat dissipation fin, and the arc portion is a transition surface for the top surface of the heat dissipation fin to transition to the flat portion below.

[0008] Optionally, the arc portion is an upwardly convex arc surface.

[0009] Optionally, one end of the arc portion is tangent to the top surface of the heat dissipation fin, and a transition fillet is provided between the other end of the arc portion and the flat portion.

[0011] Optionally, the heat dissipation fins include first heat dissipation fins and second heat dissipation fins. The first heat dissipation fins extend along the length direction of the protective shell housing, and the second heat dissipation fins are arranged on both sides in the width direction of the array formed by the first heat dissipation fins. The second heat dissipation fins are located between the outermost first heat dissipation fins and the edge of the protective shell housing.

[0012] Optionally, the notch is only provided on the first heat dissipation fins.

The included angle between the first inclined plate and the side surface of the first heat dissipation fin is an acute angle, and the included angle between the second inclined plate and the side surface of the first heat dissipation fin is an obtuse angle.

[0014] The present utility model further provides an inverter, including the above-mentioned protective shell heat dissipation structure.

[0015] The inverter and its protective shell heat dissipation structure provided by the embodiments of the present utility model, compared with the prior art, have the following advantages:

[0016] 1. Notches are provided on multiple heat dissipation fins on the protective shell, and each notch forms a dot matrix pattern as a point, so as to display a logo. This design does not affect the distribution range of the heat dissipation fins on the protective shell housing;

[0028] First embodiment

[0029] Please refer to Figure 1, in the embodiment of the present utility model, a heat dissipation structure for a protective case is provided. Exemplarily, the protective case can be a protective case for various devices with heat dissipation requirements. The heat dissipation structure of the protective case includes multiple heat dissipation fins 2, and all the heat dissipation fins 2 are vertically arranged on the outer surface of the protective case housing 1, and the two are integrally formed; the protective case housing 1 is made of a metal material with high heat dissipation efficiency, and the heat dissipation fins 2 are formed by casting or die-casting while manufacturing the protective case housing 1, and then the sharp edges of the heat dissipation fins 2 are removed by machining and processed into rounded chamfers.

[0030] Please refer to Figure 1 , there are two types of heat dissipation fins 2: the first heat dissipation fins 21 and the second heat dissipation fins 22. Multiple first heat dissipation fins 21 are arranged on the outer surface of the protective case housing 1 parallel to each other and at equal distances, and the length of the first heat dissipation fins 21 extends along the length direction of the protective case housing 1. The array formed by all the first heat dissipation fins 21 is at the same distance from the two edges in the width direction of the protective case housing 1, and the second heat dissipation fins 22 are arranged between the outermost first heat dissipation fins 21 in the array and the edges in the width direction of the protective case housing 1.

[0031] Please refer to Figure 1 , there are also two types of the second heat dissipation fins 22: the first inclined plate 221 and the second inclined plate 222. Half of the number of the first inclined plates 221 and half of the number of the second inclined plates 222 are arranged on each side of the first heat dissipation fin array in the width direction of the protective case housing 1, and the first inclined plate 221 and the second inclined plate 222 are symmetric about the axis in the width direction of the protective case housing 1. All the first inclined plates 221 on one side of the first heat dissipation fin array are parallel to each other and at equal distances, and all the second inclined plates 222 are parallel to each other and at equal distances.

[0032] Please refer to Figure 2 , the included angle a between the first inclined plate 221 and the side surface of the first heat dissipation fin 21 is an acute angle, and the included angle b between the second inclined plate 222 and the side surface of the first heat dissipation fin 21 is an obtuse angle.

[0033] Please refer to Figure 1 , in the above first heat dissipation fin array, notches 211 are provided on some or all of the first heat dissipation fins 21. Exemplarily, the notches 211 can penetrate the opposite side surfaces of the first heat dissipation fins 21, or can not penetrate; in the first embodiment, the notches 211 penetrate the opposite side surfaces of the first heat dissipation fins 21. Exemplarily, the bottom of the notches 211 can be as deep as flush with the surface of the protective case housing 1, and the depth of the notches 211 can also not completely cut off the first heat dissipation fins 21; in the first embodiment, the depth of the notches 211 is 1 / 4 - 1 / 2 of the height of the first heat dissipation fins 21.

[0034] Please refer to Figure 1, the above-mentioned notch 211 is only provided on the first heat dissipation fin 21, which means that the notch 211 is not provided on the second heat dissipation fin 22. The notch 211 is provided on the first heat dissipation fin 21, which can break the higher part of the longer heat dissipation fin 2 into multiple segments. During the transportation, installation or use of the product, the first heat dissipation fin 21 will not be deformed as a whole after being impacted, avoiding the situation that the first heat dissipation fin 21 is tilted and leaned against the side surface of the adjacent first heat dissipation fin 21 after being deformed as a whole, and enclosing a longer cavity with the adjacent first heat dissipation fin 21 to reduce the heat dissipation efficiency. The length of the second heat dissipation fin 22 is shorter, and its length is much shorter than that of the first heat dissipation fin 21. Therefore, the second heat dissipation fin 22 itself has stronger anti-deformation ability than the first heat dissipation fin 21, so there is no need to provide a notch 211 on the second heat dissipation fin 22.

[0035] Please refer to Figure 1 , notches 211 are provided on multiple first heat dissipation fins 21. Some first heat dissipation fins 21 have only one notch 211, and some first heat dissipation fins 21 have multiple notches 211. Each notch 211 is equivalent to a pixel point, and all notches 211 form a pixel dot matrix, thus forming a dot matrix pattern of the logo. Exemplarily, the pattern of the logo can be a graphic, a Chinese character or a letter. In the first embodiment, the pattern of the logo is the letter V.

[0036] Please refer to Figure 1 , since the notch 211 penetrates the opposite side surfaces of the first heat dissipation fin 21, the pixel point corresponding to the notch 211 will become clearer and more distinguishable because some of the ridges of the first heat dissipation fin 21 are missing.

[0037] Please refer to Figure 3 , the notch 211 includes a flat portion 2111 and two arc portions 2112. The flat portion 2111 is located at the bottom of the notch 211, and the arc portions 2112 are located on both sides of the flat portion 2111 along the length direction of the first heat dissipation fin 21. The arc portions 2112 are transition surfaces for the top surface of the first heat dissipation fin 21 to transition to the flat portion 2111 below. The arc portions 2112 are upwardly convex arcs, and one end of each arc portion 2112 is tangent to the top surface of the first heat dissipation fin 21, and the other end is connected to the flat portion 2111 through a transition fillet 2113.

[0038] Please refer to Figure 3 , the connecting lines of the corresponding parts of the adjacent notches 211 on the adjacent first heat dissipation fins 21 are parallel to each other. Exemplarily, points A1 and B1 are selected in any one notch 211, then point A2 corresponding to the position of A1 and point B2 corresponding to the position of B1 are selected from the adjacent notches 211 on the adjacent first heat dissipation fins 21, and then the connecting line A1A2 is parallel to the connecting line B1B2.

[0039] The heat dissipation structure of the protective case provided in this embodiment forms a dot matrix pattern with each notch 211 as a point by arranging notches 211 on multiple first heat dissipation fins 21 on the protective case housing 1, so as to display a logo. This design does not affect the distribution range of the heat dissipation fins 2 on the protective case housing 1, thus realizing the setting of a prominent logo pattern while the surface of the protective case housing 1 is covered with heat dissipation fins 2.

[0040] Second Embodiment

[0041] This embodiment provides an inverter, including the heat dissipation structure of the protective case provided in the foregoing embodiment, and this heat dissipation structure of the protective case is arranged on the protective case of the inverter.

[0042] The inverter provided in this embodiment forms a dot matrix pattern with each notch 211 as a point by arranging notches 211 on multiple first heat dissipation fins 21 on the inverter protective case, so as to display a logo. This design does not affect the distribution range of the heat dissipation fins 2 on the inverter protective case, thus realizing the setting of a prominent logo pattern while the surface of the inverter protective case is covered with heat dissipation fins 2.

[0043] As described above, the above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
