[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides the following technical solutions: A micro-encapsulated inverter module that is easy to install, including: an inverter module body 1. In the present technical solution, the inverter module body 1 is provided with connection pins on its side wall. This mechanism is a conventional technology in the art and has no relevance to the technical problems in the present technical solution. Therefore, no more description will be made in the present technical solution. In specific use, the micro-encapsulated inverter module body 1 is installed at a specified position according to the design requirements to ensure that the pins or interfaces of the inverter module body 1 are correctly connected to other parts of the system. According to the design and working principle of the inverter module body 1, a suitable local oscillator signal is set.

[0021] The bottom of the inverter module body 1 is sleeved on the installation base plate 2. The top of the installation base plate 2 is fitted with a rubber sleeve 3. The inner wall of the rubber sleeve 3 is sleeved with the bottom of the longitudinal end of the support frame 4. The intersection of the support frame 4 and the installation base plate 2 is connected with a first bolt 5. The upper section of the longitudinal end of the support frame 4 is connected with a heat sink 7 by a second bolt 6. The bottom of the heat sink 7 abuts against the inverter module body 1. A ventilation slot 8 is opened at the top of the support frame 4, and a cooling fan 9 is fitted in the ventilation slot 8. A clamping block 10 is provided on the side wall of the cooling fan 9 and is snap-connected to the support frame 4. The bottom of the cooling fan 9 abuts against the heat sink 7.

[0022] Preferably: The installation base plate 2, the rubber sleeve 3, the support frame 4 and the first bolt 5 form a threaded connection structure.

[0023] During specific use, the rubber sleeve 3 sleeved at the bottom of the support frame 4 is fitted into the installation slot at the top of the installation base plate 2 and fixed by the first bolt 5.

[0024] Preferably: The support frame 4, the second bolt 6 and the heat sink 7 form a threaded connection structure. Four card slots are provided on the outside of the ventilation slot 8 at the top of the support frame 4, and the shape and size of the card slots are consistent with those of the clamping block 10.

[0025] During specific use, the heat sink 7 installed on the support frame 4 through the second bolt 6 abuts against the top surface of the variable frequency module body 1, thereby conducting the heat generated by it. At the same time, the clamping block 10 is clamped in the card slot at the top of the support frame 4 to fix the connection of the radiator fan 9 on the support frame 4.

[0026] Preferably: A slider 11 is slidably connected to the bottom of the mounting base plate 2. The bottom of the slider 11 is connected to a rubber plate 12. A limiting block 13 is provided at the top of one side of the rubber plate 12 and is snap-fitted to the mounting base plate 2.

[0027] During specific use, by pulling the limiting block 13 clamped on the mounting base plate 2 outward, the rubber plate 12 can be replaced by sliding the slider 11 at the bottom of the mounting base plate 2.

[0028] Preferably: The slider 11 is of a "T" shape and its shape and size match the bottom chute of the mounting base plate 2. Four sliders 11 are evenly distributed on the top of the rubber plate 12.

[0029] During specific use, the slider 11 evenly distributed on the top of the rubber plate 12 enables it to stably support the mounting base plate 2 slidably connected above.

[0030] Preferably: A circular groove is provided at the chute of the mounting base plate 2, and its shape and size match the rubber convex block at the top of the limiting block 13.

[0031] During specific use, the groove provided on the bottom chute of the mounting base plate 2 facilitates the fixing of the connection between the rubber plate 12 at its bottom and it by using the limiting block 13.

[0032] Working principle: When the variable frequency module body 1 needs to be installed, the rubber plate 12 slidably connected to its bottom is adhered to the surface of the installation part, thereby facilitating the installation of the variable frequency module body 1. At the same time, when the installation position needs to be changed, only by pulling the limiting block 13 clamped on the mounting base plate 2 outward, the rubber plate 12 can be replaced by sliding the slider 11 at the bottom of the mounting base plate 2. After the variable frequency module body 1 is installed, the heat generated during its operation is conducted by the heat sink 7 installed on the support frame 4 through the second bolt 6 and abutting against the top surface of the variable frequency module body 1. While increasing the heat dissipation area, the heat on the heat sink 7 is ventilated and dissipated by the radiator fan 9 abutting above it, so as to improve the heat dissipation efficiency of the variable frequency module body 1. At the same time, the rubber sleeve 3 sleeved at the bottom of the support frame 4 is fitted into the installation groove at the top of the mounting base plate 2 and fixed by the first bolt 5, so that the support frame 4 can be stably fixed on the top of the mounting base plate 2, preventing it from shaking in the installation groove at the top of the mounting base plate 2 under the influence of the operation of the radiator fan 9. At the same time, after long-term use, the connecting ear on the outside of the radiator fan 9 can be pulled upward regularly, so as to separate the clamping block 10 clamped and fixed on the top of the support frame 4, facilitating the disassembly of the radiator fan 9 for cleaning and maintenance.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
