DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a structure for preventing condensation in a motor controller, including a housing main body 1, and a first cover plate 2 and a second cover plate 5 are respectively installed on both sides of the housing main body 1;
[0023] A cooling fan 4 is installed on the first cover plate 2, a storage case 6 is installed on the second cover plate 5, a plurality of valve bodies 7 are evenly installed on the outer side of the storage case 6, a frame 10 is installed inside the storage case 6, filter nets 13 are symmetrically installed on both sides of the frame 10, and a desiccant is filled inside the frame 10.
[0024] As shown in Figure 2 and Figure 4 : A plurality of air holes 8 are evenly opened on the storage case 6, and the positions of the plurality of air holes 8 correspond to the positions of the valve bodies 7; Through the above settings, the valve bodies 7 can be opened when the cooling fan 4 is running, so that the outside air can enter the inside.
[0025] As shown in Figure 4 : Two threaded cylinders 12 are symmetrically installed on the upper surface of the frame 10; Through the above settings, the threaded cylinders 12 can fix the frame 10 and the storage case 6 together.
[0026] As shown Figure 4 : Two through holes 9 are symmetrically formed on the upper surface of the storage shell 6, and the through holes 9 are connected to the threaded cylinders 12 by bolts; with the above arrangement, the two through holes 9 can make it more convenient for the bolts to be connected to the threaded cylinders 12.
[0027] As shown Figure 4 : A feed inlet 11 is formed in the middle of the upper surface of the frame 10; with the above arrangement, it is convenient to carry out the replacement work of the desiccant.
[0028] As shown Figure 4 : A cover body 14 is installed on the feed inlet 11; with the above arrangement, the desiccant inside is sealed, avoiding the situation that the desiccant spills out.
[0029] As shown Figure 1 and Figure 3 : A wire outlet hole 3 for the wire to extend out is formed on the first cover plate 2; with the above arrangement, it is convenient to carry out the installation work of the wire.
[0030] Working principle: When the cooling fan 4 operates, the valve body 7 is opened, so that the outside air enters the inside of the storage shell 6 through the valve body 7 and the air holes 8. The air passes through the desiccant inside the frame 10 to absorb the moisture inside the air, and then enters the inside of the housing main body 1 to cool the internal components, and then is drawn away by the cooling fan 4. The internal components are cooled by the dry air, thus avoiding the situation of condensation inside the equipment.
[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
