[0033] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

Therefore, the example term "below..." can include both upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.
[0037] The existing reactor has poor heat dissipation performance because the heat dissipation area of the reactor core group is small and adjacent core sheets need to fit together, so there is not enough heat dissipation space and heat can only be dissipated through the outer surface.
[0038] The poor heat dissipation performance of the reactor will not only reduce the reliability of the air-conditioning side outlet outdoor unit, but also increase the production cost of the outdoor unit in order to achieve the required heat dissipation effect. The reason is that the outdoor unit is limited by its own structure. Generally, the reactor is installed on one side of the air duct. The location of the reactor is not enough to set up a sufficient ventilation duct for the heat dissipation of the reactor. Therefore, the size of the whole machine can only be increased to set up the heat dissipation duct structure. At the same time, the production material of the reactor needs to be changed from aluminum wire to copper wire with better heat dissipation, which greatly increases the production cost of the whole machine.
[0039] In view of this, the present embodiment provides a reactor, which makes structural improvements to the core group of the reactor, and designs the core group to include a first iron core sheet and a second iron core sheet of unequal sizes in the second direction, so that two adjacent first iron core sheets form a heat dissipation gap on at least one side of the second iron core sheet, which can effectively improve the heat dissipation performance of the reactor and the reliability of the external machine, and at the same time reduce the heat dissipation cost of the reactor, thereby reducing the production cost of the external machine.
[0040] The following is combined with Figure 1-5 The structure of the reactor provided in this embodiment is described.
[0041] Figure 1 The schematic diagram of the structure of the reactor according to the embodiment of the utility model is schematically shown. Figure 2 The structure diagram of the reactor according to the embodiment of the utility model from another perspective is schematically shown. Figure 3The schematic diagram schematically shows the structure of the reactor according to the embodiment of the utility model from another perspective.
[0042] Combined with Figure 1 , Attachment Figure 2 And attached Figure 3 As described in, the first aspect of this embodiment provides an inductor 100, which includes a working winding 10 and a core group 20, the working winding 10 is wound on the core group 20, the first core sheet 21 and the second core sheet 22 of this embodiment can both be silicon steel sheets, and multiple first core sheets 21 and multiple second core sheets 22 are stacked. The stacking form can be multiple first core sheets 21 stacked and connected, multiple second core sheets 22 stacked and connected, only one first core sheet 21 is adjacent to a second core sheet 22, or, at least one side of each first core sheet 21 can be adjacent to a second core sheet 22.
[0043] Specifically, a plurality of first core sheets 21 and a plurality of second core sheets 22 may be alternately arranged on the working winding 10 along the first direction X, so that there is a second core sheet 22 between two adjacent first core sheets 21, a first core sheet 21 is provided between two adjacent second core sheets 22, and adjacent first core sheets 21 and second core sheets 22 are superimposed on each other to form a core group 20 structure. This form can not only form a plurality of heat dissipation fins using the first core sheets, but also form the heat dissipation intervals 23 described below.
[0044] The working winding 10 of the present embodiment is formed by enameled wire, which can generally be composed of aluminum wire plus an outer layer of insulating varnish, or copper wire plus an outer layer of insulating varnish. However, the cost of copper wire is relatively high. When the core group 20 of the structure of the present embodiment is adopted, the enameled wire is preferably made of aluminum wire to save costs.
[0045] In this embodiment, the first direction X may be understood as the thickness direction of the core assembly 20 itself, or may be understood as the length direction of the working winding 10 .
[0046] In order to improve the heat dissipation performance of the reactor 100, this embodiment makes structural improvements to the iron core group 20 that accounts for the largest volume in the reactor 100, and at least part of the edge of the first iron core sheet 21 is protruded from the edge of the second iron core sheet 22, so that the protruding part of the first iron core sheet 21 forms a structure in the form of heat dissipation fins, thereby improving the heat dissipation performance of the reactor 100. While improving the reliability of the external machine, there is no need to design the size of the whole machine too large to add a heat dissipation duct, which can reduce the heat dissipation cost of the reactor 100, and relatively low-cost aluminum can be used as the material of the working winding 10 of the reactor 100, thereby reducing the production cost of the reactor 100 and the entire external machine.
[0047] It should be noted that the above-mentioned setting of at least part of the edge of the first iron core sheet 21 protruding from the edge of the second iron core sheet 22 can be understood as one end or the circumferential edge of the first iron core sheet 21 protruding from the edge of the second iron core sheet 22, or part of the edge of one end of the first iron core sheet 21 protruding from the edge of the second iron core sheet 22, etc., as long as part of the edge of the first iron core sheet 21 protrudes from the edge of the second iron core sheet 22, it will be sufficient.
[0048] Further, along the second direction Y perpendicular to the first direction X, one end or one end of the first core sheet 21 protrudes from the edge of the second core sheet 22, so that two adjacent first core sheets 21 form a heat dissipation gap 23 at at least one end of the second core sheet 22. At this time, the size of the first core sheet 21 in the second direction Y is greater than the size of the second core sheet 22 in the second direction Y.
[0049] It can be seen that, unlike the traditional structure in which multiple iron core sheets overlap each other and are equal in size, the inductor 100 provided in this embodiment has a first iron core sheet 21 and a second iron core sheet 22 of two different sizes. Since at least one end of the second iron core sheet 22 is shorter than the first iron core sheet 21, two adjacent first iron core sheets 21 form a heat dissipation gap 23 at at least one end of the second iron core sheet 22. The heat dissipation gap 23 can increase the heat dissipation area of the inductor 100, thereby effectively improving the heat dissipation performance of the inductor 100.
[0050] Combined with Figure 2 As described in some examples, optionally, along the second direction Y, the second core piece 22 of the present embodiment has opposite first ends 221 and second ends 222 , and two adjacent first core pieces 21 have heat dissipation gaps 23 at the first ends 221 and the second ends 222 .
[0051] Among them, the above-mentioned "first end 221 and the second end 222" can be understood as the areas relative to the two ends of the second iron core sheet 22 and their vicinities. The side edges of the second iron core sheet 22 at the first end 221 and the side edges of the second end 222 can be parallel or approximately parallel to each other. As can be seen from the figure, since the sizes of the second iron core sheet 22 at the first end 221 and the second end 222 are smaller than those of the first iron core sheet 21, the two adjacent first iron core sheets 21 both have the heat dissipation gap 23 at the first end 221 and the second end 222, and can have good heat dissipation efficiency.
[0052] In some examples, optionally, the heat dissipation gap 23 at the first end 221 and the heat dissipation gap 23 at the second end 222 are equal in size.
[0053] Specifically, it can be understood that in the second direction Y, the distance between one end of the second core sheet 22 and one end of the first core sheet 21 adjacent thereto is equal to the distance between the other end of the second core sheet 22 and the other end of the first core sheet 21 adjacent thereto. In this way, the heat dissipation efficiencies of the opposite ends of the core group 20 in the second direction Y of this embodiment can be the same or substantially the same, thereby ensuring the uniformity of heat dissipation of the core group 20.
[0054] In some examples, optionally, along the second direction Y, the size of the first core sheet 21 is a, the size of the second core sheet 22 is b, and the difference between a and b is 10-50 mm. This can achieve better heat dissipation while ensuring the working effect and structural strength of the core.
[0055] Further, the difference between a and b can be 20-40 mm. When the heat dissipation intervals 23 on both sides have the same size in the second direction, the size of each heat dissipation interval 23 is 10-20 mm, or it can be understood that the size of the protruding portion on one side of the first core sheet 21 is 10-20 mm. Of course, the difference in the specific size of the first core sheet 21 and the second core sheet 22 in the second direction Y of this embodiment is not limited thereto, and can be determined according to the requirements of the heat generation and the peripheral size of the reactor 100, which are not listed one by one in this embodiment.
[0056] Combined with Figure 3 As shown in, in some examples, optionally, in the third direction Z, at least one end edge of the first iron core sheet 21 of the present embodiment is arranged to protrude from the edge of one end of the second iron core sheet 22, so that two adjacent first iron core sheets 21 form a heat dissipation gap 23 at at least one end of the second iron core sheet 22, and the third direction Z is perpendicular to the first direction X and the second direction Y.
[0057] At this time, the size of the first iron core piece 21 in the second direction Y is larger than that of the second iron core piece 22, and the size of the first iron core piece 21 in the third direction Z is also larger than that of the second iron core piece 22, so that the sizes of multiple ends of the first iron core piece 21 of this embodiment are larger than the sizes of the second iron core piece 22 of this embodiment, forming heat dissipation gaps 23 at multiple ends, which can improve the heat dissipation effect.
[0058] In some examples, optionally, along the third direction, the second core sheet 22 of the present embodiment has a third end 223 and a fourth end 224 opposite to each other, and two adjacent first core sheets 21 have a heat dissipation gap 23 at the third end 223 and / or the fourth end 224 .
[0059] Two adjacent first core sheets 21 may be Figure 3 As shown in FIG. 2 , the heat dissipation gap 23 is formed only at the third end 223 , so as to facilitate the second core sheet 22 to be connected to the mounting assembly 30 described below, thereby improving the connection stability between the core assembly 20 and the mounting assembly 30 .
[0060] Of course, it is also possible that two adjacent first iron core sheets 21 of the present embodiment have the heat dissipation gap 23 at the first end 221, the second end 222, the third end 223 and the fourth end 224 (this embodiment is not shown in the figure), so that the first iron core sheet 21 and the second iron core sheet 22 can utilize the heat dissipation gap 23 on all sides for heat dissipation, further improving the heat dissipation performance of the reactor 100.
[0061] Figure 5 The schematic diagram of the structure of the core group 20 of the reactor 100 according to the embodiment of the present utility model is schematically shown.
[0062] Combined with Figure 5 As shown in, in some examples, optionally, the first iron core sheet 21 of the present embodiment includes a first sheet 211 and a second sheet 212 connected to each other, and at least one of the first sheet 211 and the second sheet 212 is provided with a mounting groove 24 for installing the working winding 10; and / or, the second iron core sheet 22 includes a third sheet 225 and a fourth sheet 226 connected to each other, and at least one of the third sheet 225 and the fourth sheet 226 is provided with a mounting groove 24 for installing the working winding 10.
[0063] The shape of the mounting groove 24 of this embodiment is determined according to the shape of the working winding 10. For example, when the cross section of the working winding 10 shown in the figure is two spaced-apart rectangles, two rectangular grooves can be opened on the first sheet 211 of this embodiment, so that the first sheet 211 is approximately E-shaped, and the second sheet 212 is formed into an I-shape. Similarly, two rectangular grooves can be opened on the third sheet 225 of this embodiment, so that the third sheet 225 is approximately E-shaped, and the fourth sheet 226 is formed into an I-shape.
[0064] During assembly, the working winding 10 can be first installed on the first sheet 211 and the third sheet 225, and then the second sheet 212 can be integrally connected to the first sheet 211 by welding or the like, and the fourth sheet 226 can be integrally connected to the third sheet 225 by welding or the like, to facilitate the assembly of the working winding 10 of this embodiment.
[0065] Of course, the shapes of the first sheet 211 and the second sheet 212 of this embodiment are not limited thereto, as long as the first sheet 211 and the second sheet 212 can form a hole matching the working winding 10 after being connected, the same applies to the third sheet 225 and the fourth sheet 226 .
[0066] Combined with the attachment again Figure 1As shown in , in some examples, optionally, the reactor 100 of this embodiment further includes a mounting assembly 30, which is connected to the core group 20 and is used to connect to the body of the air conditioner outdoor unit. When assembling the outdoor unit, the mounting assembly 30 is connected to the body of the outdoor unit to complete the installation and fixation of the reactor 100.
[0067] In some examples, optionally, the mounting assembly 30 of this embodiment includes a mounting plate 31 and a connector (not shown in the figure), the mounting plate 31 is provided with a connecting hole 311, the connector is passed through the connecting hole 311, and is used to connect to the body of the air conditioner outdoor unit.
[0068] The mounting plate 31 of this embodiment is connected to one side of the two opposite sides of the core group 20 in the second direction Y, and the first direction X is parallel to the plate surface of the mounting plate 31. The mounting plate 31 is connected to the first core sheet 21 and the second core sheet 22 as a whole by welding or the like, and a connecting hole 311 is provided on the mounting plate 31. The connecting hole 311 is a through-hole structure so that a connecting member can be installed in the connecting hole 311. The connecting member of this embodiment can be a screw or a bolt, which is connected to the screw hole on the body through the screw or the bolt.

[0070] Combined with Figure 1 and attached Figure 4 As shown in , in some examples, optionally, the reactor 100 of this embodiment further includes a wiring terminal 40, which is connected to the working winding 10, and the wiring terminal 40 is conductively connected to the working winding 10 and is used to connect other electrical components on the outdoor unit body.
