Description

Technical Field

[0001] This utility model relates to the field of spinning equipment technology, specifically to a heat dissipation structure for a frequency converter used in a rotor spinning machine. Background Technology

[0002] Rotor spinning machines generate a lot of heat during operation because they use a large number of frequency converters. At the same time, the working environment contains a lot of dust, lint, and other debris. These lint and debris can drift into the inside of the frequency converter through door gaps and holes in the door panel. The presence of a large amount of these lint and debris will reduce the heat dissipation efficiency of the frequency converter, thus causing malfunctions and reducing its service life.

[0003] Existing technologies exist to address these issues, such as using axial fans for air extraction and adding sealing strips to door seams, and installing filters at door air inlets. However, these methods cannot prevent short fibers from accumulating on the inverter's heat sink and protruding electrical components, resulting in poor heat dissipation or requiring frequent cleaning. This can lead to frequent malfunctions or significant manpower waste. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation structure for a frequency converter used in a rotor spinning machine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation structure for a frequency converter used in a rotor spinning machine, comprising: a heat dissipation hole at the upper end of the frequency converter body and an operation hole at the rear end, an axial fan at the outer end of the operation hole, the axial fan being fixedly installed on the rear side wall of the frequency converter body by a fan bracket, and the axial fan blowing air onto the frequency converter heat sink and frequency converter capacitor located at the inner end of the frequency converter body.

[0006] Preferably, the inner end of the inverter body is provided with a mounting cavity, and the operation hole and heat dissipation hole are both connected to the mounting cavity.

[0007] Preferably, the inverter heat sink and inverter capacitor are fixed inside the mounting cavity, with the inverter heat sink and inverter capacitor facing the operation hole and located directly below the heat dissipation hole.

[0008] Preferably, a number of mounting plates are fixedly installed on the outer side of the fan bracket by bolts, and each mounting plate has a round hole on its side wall.

[0009] Preferably, the axial fan is fixed to the outside of the mounting plate by bolts and is located at the outer end of the circular hole.

[0010] Preferably, a second dustproof net is fixedly installed on the outer side of the fan bracket by bolts, and the second dustproof net is located on the outer side of the axial flow fan.

[0011] Preferably, a dustproof mesh is fixedly installed inside the heat dissipation hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention fixes the fan bracket to the outside of the operating hole, and then installs a dustproof net on the outside of the fan bracket. When the axial fan starts, it blows air onto the inverter heat sink, inverter capacitors and other electronic components, so that short fibers cannot accumulate on the heat sink and capacitors. This eliminates the need for frequent cleaning of the inverter heat sink and protruding electrical components, and provides good heat dissipation, saving a lot of manpower and resources.

[0018] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please see Figures 1-3This utility model provides a technical solution: a heat dissipation structure for a frequency converter used in a rotor spinning machine, comprising: a heat dissipation hole 3 at the upper end of the frequency converter body 1 and an operation hole 2 at the rear end; an installation cavity is provided at the inner end of the frequency converter body 1; the operation hole 2 and the heat dissipation hole 3 are both connected to the installation cavity; a frequency converter heat sink 4 and a frequency converter capacitor 5 are fixed in the installation cavity; the frequency converter heat sink 4 and the frequency converter capacitor 5 are directly opposite the operation hole 2 and located directly below the heat dissipation hole 3 (frequency converters for rotor spinning machines are existing technology, therefore, the frequency converter heat sink 4 and the frequency converter capacitor 5...). The installation method inside the inverter is also existing technology, so it will not be elaborated here. An axial fan 8 is provided at the outer end of the operation hole 2. The axial fan 8 is fixedly installed on the rear side wall of the inverter body 1 by the fan bracket 6. The axial fan 8 blows air on the inverter heat sink 4 and inverter capacitor 5 located at the inner end of the inverter body 1. Due to the air blowing by the fan, short fibers cannot accumulate on the protruding parts such as the heat sink and capacitor. There is no need to frequently clean the inverter heat sink and protruding electrical components. The heat dissipation effect is good, saving a lot of manpower and material resources.

[0020] Several mounting plates 7 are fixedly installed on the outside of the fan bracket 6 by bolts. Each mounting plate 7 has a round hole on its side wall. The axial fan 8 is fixed to the outside of the mounting plate 7 by bolts and is located at the outer end of the round hole. The axial fan 8 is fixedly installed on one side of the inverter body 1. Several axial fans 8 blow air onto the inverter heat sink 4, inverter capacitor 5 and other electronic components.

[0021] Specifically, by fixing the mounting plate 7 to the outer end of the fan bracket 6, fixing the axial fan 8 to the outer end of the mounting plate 7, and then fixing the fan bracket 6 to the rear end of the inverter body 1 and to the outer end of the operation hole 2, when the axial fan 8 starts, it blows air onto the inverter heat sink 4, inverter capacitor 5 and other electronic components, so that short fibers cannot accumulate on the heat sink and capacitors and other protruding parts, eliminating the need for frequent cleaning of the inverter heat sink and protruding electrical components, and providing good heat dissipation, saving a lot of manpower and resources.

[0022] like Figure 1 and Figure 3 As shown, in some embodiments, a second dustproof net 10 is fixedly installed on the outside of the fan bracket 6 by bolts. The second dustproof net 10 is located on the outside of the axial fan 8. A first dustproof net 9 is fixedly installed inside the heat dissipation hole 3. More specifically, the second dustproof net 10 does not contact the fan blades of the axial fan 8. The second dustproof net 10 filters the air blown towards the inverter heat sink and protruding electrical components. The first dustproof net 9 blocks and filters the heat dissipation hole 3 to prevent foreign objects from entering the inverter body 1 and damaging the inverter.

[0023] In actual use, the fan bracket 6 is fixedly installed on the outer end of the operating hole 2 by the fan bracket 6, and then the dustproof net 10 is installed on the outside of the fan bracket 6. When the axial fan 8 is started, it blows air onto the inverter heat sink 4, inverter capacitor 5 and other electronic components, so that short fibers cannot accumulate on the heat sink and capacitors and other protruding parts. There is no need to clean the inverter heat sink and protruding electrical components frequently, and the heat dissipation effect is good, saving a lot of manpower and material resources.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
