Description

Technical Field

[0001] The utility model belongs to the technical field of power equipment, and particularly relates to an inverter. Background Art

[0002] An inverter is an electronic device that converts direct current (DC) into alternating current (AC). It is widely used in various electronic devices, electrical appliances and daily tools, as well as in occasions where battery charging is required. The main part of the inverter is the inverter circuit, and it also includes control, protection and filtering circuits. Inverters are mainly divided into two categories, one is classified according to the nature of the wave string, and the other is classified according to the nature of the source current. Inverters have the characteristics of high conversion efficiency, fast startup, good safety performance, good physical performance, and strong load adaptability and stability. Common inverters include half-bridge inverters and full-bridge inverters.

[0003] The components of the inverter that need to dissipate heat generally include reactance (also known as inductance) and power components such as IGBT (Insulated Gate Bipolar Transistor) power modules. Specifically, heat dissipation fins are provided on the outer shell of the inverter, and the heat dissipation fins are used to enable heat exchange between the internal space of the inverter and the external environment for heat dissipation. However, the heat dissipation efficiency of the heat dissipation fins is low, and the heat dissipation effect is not good. Heat is easily accumulated inside the inverter, which in turn causes the internal temperature of the inverter to rise. If the internal temperature of the inverter is too high, it will lead to poor working conditions of the inverter. If the internal temperature of the inverter remains too high for a long time, there will be a risk of burning out the machine. Summary of the Utility Model

For those of ordinary skill in the art, without creative efforts, other drawings can be obtained according to these drawings, and other implementation manners can also be obtained. Additionally, the terms related to directions only represent the relative positional relationships between components, rather than absolute positional relationships.

[0032] The embodiments of the present invention provide an inverter. Please refer to Figures 1-10 , which mainly includes an inverter body 1, a heat dissipation housing 2, a flow guiding component 3, a refrigeration component 4, heat dissipation holes 5, and a cooling channel 6.

[0033] It should be noted that, taking Figure 2 the perspective as a reference benchmark, Figure 2 the left - right direction in Figure 2 is the left - right direction in the following text, that is, the width direction; Figure 3 the up - down direction in

[0034] is the up - down direction in the following text, that is, the height direction;

[0035] the left - right direction in

[0034] is the front - back direction in the following text, that is, the length direction.

[0035] In the embodiments of the present application, the inverter includes an inverter body 1. The inverter body 1 is the hardware part for realizing the inverter function and the housing arranged on the outer periphery of the hardware part. The hardware can be, for example, a Field - Programmable Gate Array (FPGA), an Integrated Circuit (IC), etc. A heat dissipation housing 2 is arranged behind the inverter body 1, a flow guiding component 3 and a refrigeration component 4 are arranged in the heat dissipation housing 2, heat dissipation holes 5 are arranged on the upper surface of the heat dissipation housing 2, the flow guiding component 3 forms a cooling channel 6 between the heat dissipation holes 5 and the heat dissipation housing 2. The heat generated by the inverter body 1 will cause the temperature of the cooling channel 6 to rise. The refrigeration component 4 forms cold air in the cooling channel 6 to reduce the temperature of the cooling channel 6. The cooling channel 6 exchanges heat with the inverter body 1 to further reduce the temperature of the inverter body 1.

[0035] Compared with the prior art, heat dissipation fins are provided on the inverter housing, and heat exchange between the internal space of the inverter and the external environment is carried out through the heat dissipation fins for heat dissipation. However, the heat dissipation efficiency of the heat dissipation fins is low, the heat dissipation effect is not good, and heat accumulation is likely to occur inside the inverter. In this application, a cold wind is formed in the cooling channel 6 by the refrigeration component 4 to perform heat exchange with the inverter body 1, so as to accelerate the heat dissipation of the inverter body 1, thereby avoiding heat accumulation inside the inverter and improving the heat dissipation effect of the inverter.

[0036] Specifically, the diversion component 3 includes a plurality of vertical plates arranged in the heat dissipation housing 2. The plurality of vertical plates are arranged in parallel in the heat dissipation housing, and a cooling channel 6 is formed between two adjacent vertical plates. Preferably, the vertical plates can be made of aluminum or copper. The heat dissipation holes 5 are hexagonal holes.

[0037] Specifically, the refrigeration component 4 includes a heat dissipation fan 41 arranged on the lower surface of the heat dissipation housing 2. The heat dissipation fan 41 blows air towards the heat dissipation holes 5 to form a cold wind in the cooling channel 6 for heat exchange with the inverter body 1.

[0038] Furthermore, the heat dissipation housing 2 includes a lower end plate, an upper end plate, a rear end plate, a left end plate and a right end plate. The upper end plate, the rear end plate, the left end plate and the right end plate are fixedly connected to each other. One end of the left end plate close to the lower end plate is provided with a first connecting plate 16 perpendicular to the left end plate. One end of the lower end plate close to the left end plate is provided with a second connecting plate 17 (as Figure 5 , Figure 10 shown). When installing the heat dissipation housing 2, the first connecting plate 16 is embedded between the second connecting plate 17 and the lower end plate. Preferably, one end of the second connecting plate 17 close to the left end plate is an arc-shaped plate.

[0039] In an implementable manner, a first mounting plate 7, a second mounting plate 8 and a third mounting plate 9 are arranged behind the heat dissipation housing 2. The second mounting plate 8 and the third mounting plate 9 are fixedly connected. The first mounting plate 7 is fixedly connected to the heat dissipation housing 2. The third mounting plate 9 can abut against one side of the first mounting plate 7 close to the heat dissipation housing 2. The second mounting plate 8 is fixedly connected to the inverter fixing device. The inverter fixing device can be a wall panel, a bracket or other devices that can fix the inverter. When installing the inverter, first fixedly connect the second mounting plate 8 to the inverter fixing device, and then move the inverter from top to bottom, so that the third mounting plate 9 is inserted between the first mounting plate 7 and the heat dissipation housing 2. Specifically, the third mounting plate 9 can abut against one side of the first mounting plate 7 close to the heat dissipation housing 2, thereby completing the installation steps of the inverter.

[0040] Furthermore, connection blocks 10 integrally connected to the second mounting plate 8 are provided on both sides of the second mounting plate 8. The connection blocks 10 are fixedly connected to the left and right sides of the heat dissipation housing 2. As can be seen from the above, the inverter body 1, the first mounting plate 7, and the heat dissipation housing 2 are fixedly connected, and the second mounting plate 8, the third mounting plate 9, and the inverter fixing device are fixedly connected. These two parts are connected by inserting the third mounting plate 9 between the first mounting plate 7 and the heat dissipation housing 2 and fixedly connecting the connection blocks 10 provided on both sides of the second mounting plate 8 to the heat dissipation housing 2. The three connection points are arranged in a triangle, and the triangle has stability, thus ensuring that the inverter will not fall off the inverter fixing device and improving the fixing strength of the inverter.

[0041] Preferably, as can be seen from the above installation steps, it is necessary to move the inverter from top to bottom so that the third mounting plate 9 is inserted between the first mounting plate 7 and the heat dissipation housing 2. At this time, connection blocks 10 are also provided on both sides of the second mounting plate 8, and the connection blocks 10 will abut against the lower surface of the inverter during the downward movement of the inverter, thus affecting the installation and fixing of the inverter. In order to prevent the inverter from being blocked by the connection blocks 10 during the movement, a chamfer is provided at one end of the connection block 10 close to the heat dissipation hole 5.

[0042] In an implementable manner, a hand-held plate 11 and a fixing plate 12 are provided on the left and right sides of the heat dissipation housing 2. One end of the fixing plate 12 is fixedly connected to the heat dissipation housing 2, and the other end is fixedly connected to the inverter body 1. One end of the hand-held plate 11 is connected to the end of the fixing plate 12 away from the heat dissipation housing 2, and the other end is provided with a rounded corner. The other end of the hand-held plate 11 is provided with a rounded corner, enabling the operator to safely pick up the inverter and then install and fix the inverter.

[0043] Furthermore, in order to make the entire inverter more beautiful, the sum of the widths of the hand-held plate 11, the fixing plate 12, and the heat dissipation housing 2 is equal to the width of the inverter body 1.

[0044] Furthermore, the fixing plate 12 is an L-shaped plate, and limiting grooves 15 are also provided on the upper and lower sides of the fixing plate 12. The inverter further includes a limiting block 13, and the limiting block 13 is embedded in the limiting grooves 15.

[0045] Furthermore, a grasping hole 14 is provided on the hand-held plate 11. On the one hand, the grasping hole 14 is used to reduce the weight of the entire inverter, and on the other hand, it enables the operator to hold the inverter more firmly.
