[0046] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0047] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings.

Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0048] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0049] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0050] As Figures 1 to 3 shown, it is a preferred embodiment of the quick-insert heat dissipation structure of the present utility model. This quick-insert heat dissipation structure includes: a radiator 1, an air duct plate 2, and a fan 3. The radiator 1 includes two side plates 11 arranged at intervals, and sliding grooves 12 are provided on the side plates 11. A plurality of heat dissipation fins 13 are arranged at intervals between the two side plates 11. Insertion strips 21 are provided on both sides of the air duct plate 2, and the two insertion strips 21 are respectively inserted into the two sliding grooves 12. The fan 3 is arranged on the air duct plate 2, and the fan 3 blows cold air to the heat dissipation fins 13 to cool and dissipate heat from the heat dissipation fins 13. The air duct plate 2 is inserted into the sliding grooves 12 of the radiator 1 through the insertion strips 21, thereby realizing the quick installation and disassembly of the air duct plate 2. During installation, the insertion strips 21 are aligned with the sliding grooves 12 and inserted, and during disassembly, the air duct plate 2 is pulled out from the sliding grooves 12. Compared with the method of connecting the radiator 1 and the air duct plate 2 with screws, this insertion method makes the disassembly and assembly of the air duct plate 2 more convenient and fast. Moreover, when the fan fails, the air duct plate 2 can be removed and then the fan can be repaired and replaced, and the repair and replacement are also more convenient.

[0051] As Figure 5As shown, the sliding groove 12 is a through groove provided on the side plate 11, that is, the length of the sliding groove 12 is equal to the length of the side plate 11. Moreover, the end faces at both ends of the sliding groove 12 are chamfered, making it more convenient for the inserting strip 21 to be inserted into the sliding groove 12. The notch of the sliding groove 12 is opened on the side wall of the side plate 11 facing the other side plate 11. The cross-sectional shape of the sliding groove 12 is composed of a section of superior arc and straight lines extending from both ends of the superior arc to the notch position, that is, the sliding groove 12 is in a converging shape near the notch position, and after the inserting strip 21 is inserted into the sliding groove 12, it will have a certain limiting effect on the inserting strip 21.

[0052] In other embodiments, the position of the notch of the sliding groove 12 can also be on other side walls of the side plate 11. For example, it can be opened on the top surface of the side plate 11, but the two sides of the corresponding air duct plate 2 need to be bent so that the inserting strip 21 can match the sliding groove 12.

[0053] In other embodiments, the shape of the sliding groove 12 can also be square, triangular or other shapes.

[0054] As Figure 6 shown, a ventilation opening is provided in the middle of the air duct plate 2, and the fan 3 is arranged at the ventilation opening, and the blown cold air will enter the heat sink 13 through the ventilation opening. Inserting strips 21 are provided on both sides of the air duct plate 2. As Figure 7 、 Figure 8 shown, the outer shape of the inserting strip 21 matches the shape of the sliding groove 12, and a cavity is also provided in the middle of the inserting strip 21. And one end of the inserting strip 21 is flush with the first end face of the air duct plate 2, and the length of the inserting strip 21 is less than the length of the air duct plate 2.

[0055] In other embodiments, the inserting strip 21 can also be arranged between the two ends of the air duct plate 2.

[0056] In other embodiments, the length of the inserting strip 21 can also be equal to the length of the air duct plate 2.

[0057] A limiting plate 5 is provided on one side of the second end face of the air duct plate 2, that is, the limiting plate 5 is provided on the side of the air duct plate 2 away from the inserting strip 21. The limiting plate 5 is perpendicular to the air duct plate 2 and is located outside the heat sink 13. When the air duct plate 2 is inserted into the sliding groove 12, it can slide in the sliding groove 12. After the limiting plate 5 is provided, the sliding stroke of the air duct plate 2 can be restricted.

[0058] A pulling hole 6 is also provided near the second end face of the air duct plate 2. After the pulling hole is provided, it is convenient to pull out the air duct plate 2 from the sliding groove 12.

[0059] As Figure 4 、 Figure 9As shown in the figure, a connector 4 is further provided on one side of the first end face of the air duct plate 2. The connector 4 includes a plug-in portion 41 and a connecting portion 42. One end of the plug-in portion 41 is connected to the connecting portion 42, and the other end is inserted into the cavity of the insertion bar 21. Specifically, the plug-in portion 41 is a plastic boss, and the size of the plug-in portion 41 gradually increases from the end away from the connecting portion 42 to the end close to the connecting portion 42. After the plastic boss is inserted into the cavity of the insertion bar 21, the vibration caused by the operation of the fan is absorbed through the deformation of the plastic boss, so that the noise reduction effect can be achieved. The outer wall of the connecting portion 42 has an external thread, and the inner wall of the sliding groove 12 has an internal thread, and the connecting portion 42 is threadedly connected to the sliding groove 12.

[0060] Further, the connector 4 further includes an operating portion 43. The operating portion 43 is connected to the end of the connecting portion 42 away from the plug-in portion 41, and the operating portion 43 can be rotated by means of a tool. Specifically, the end face of the operating portion 43 is provided with a special-shaped groove, and the special-shaped groove includes but is not limited to a cross-shaped groove, a straight-shaped groove, and a star-shaped groove. By providing the special-shaped groove, it is convenient to install and disassemble the connector 4 by means of a screwdriver and other tools with corresponding shapes.

[0061] In other embodiments, the side surface of the operating portion 43 may also have raised or sunken patterns, and the operating portion 43 can also be rotated by means of tools such as pliers to install and disassemble the connector 4.

[0062] This embodiment also provides an inverter, which includes a quick-insert heat dissipation structure and a casing 7. The quick-insert heat dissipation structure has the same structure as the quick-insert heat dissipation structure in the above embodiment, so it will not be described in detail. The radiator 1 in the quick-insert heat dissipation structure is arranged on the casing 7, and the top of the casing 7 has hanging corners for hanging the casing 7 on the wall.

[0063] The installation and disassembly process of the inverter provided in this embodiment is described as follows:

[0064] The installation process is as follows: Install the radiator 1 on the casing 7, and then slide the air duct plate 2 into the sliding groove 12 of the radiator 1. After sliding in place, set the connector 4 so that the plug-in portion 41 of the connector 4 is inserted into the cavity of the insertion bar 21, and the connecting portion 42 is threadedly connected to the sliding groove 12. Then install the fan 3 at the ventilation opening of the air duct plate 2. Finally, hang the casing 7 on the wall. The disassembly process is opposite to the steps of the installation process.

[0065] During the operation of the inverter, if the fan 3 fails, first remove the connector 4, and then pull out the air duct plate 2 from the sliding groove 12 of the radiator 1 through the pull hole 6. Then remove the fan 3 for repair or replacement.

[0066] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to exhaustively list all implementation manners here. And the obvious changes or alterations derived therefrom still fall within the protection scope of this invention.
