[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0024] The ABB frequency converter is an electrical device used to control the speed of an electric motor. By adjusting the output frequency and voltage, it can change the speed and torque of the motor so that it can work according to actual needs1. The frequency converter converts alternating current with a fixed frequency into an alternating current power supply with a variable frequency and variable voltage.
[0025] Embodiment 1:
[0026] Based on the technical defect of poor heat dissipation caused by the lack of a wind guiding mechanism in the prior art, please refer to Figures 1 - 6 , a kind of ABB frequency converter with a heat dissipation function provided by the present utility model. Under the action of the guide plate 61, the wind blown by the cooling fan 3 can be quickly directed to the heat dissipation fins 62 under the guiding action of the hump at the bottom of the guide plate 61, and the heat conducting block 64 and the heat pipe 63 gather the heat on the heat dissipation fins 62, and then the heat can be quickly blown out from the heat dissipation holes 7 on both sides to achieve the purpose of rapid heat dissipation. It includes a housing 1, a wind cavity is provided at the bottom of the housing 1, two slots 2 are opened in the wind cavity, and a cooling fan 3 and a filter screen 4 are inserted through the two slots 2. The cooling fan 3 is above the filter screen 4. A cover assembly 5 is also provided on the side wall at the bottom of the housing 1, and a heat dissipation assembly 6 is installed above the cooling fan 3 in the wind cavity; when the ABB frequency converter works, the cooling fan 3 starts, and the external air is filtered by the filter screen 4 and blown into the wind cavity. Under the action of the heat dissipation assembly 6, the heat can be quickly blown out from the heat dissipation holes 7 to achieve rapid heat dissipation.
[0027] To smoothly conduct the heat out, please refer to Figure 4 , the heat dissipation assembly 6 includes a guide plate 61 fixed in the wind cavity. Heat dissipation fins 62 are fixedly provided at both ends of the guide plate 61, and both ends of the guide plate 61 are embedded and fixedly connected to both ends of the heat pipe 63. The heat pipe 63 extends to the position of the heating element and is fixedly provided with a heat conducting block 64 in contact with the heating element; since the heat conducting block 64 is in contact with the heating element, the heat generated when the heating element operates is transferred to the heat pipe 63 through the heat conducting block 64 and then transferred to the heat dissipation fins 62 on the guide plate 61.
[0028] To achieve the guidance of the blowing air, the middle part of the deflector 61 is in the shape of a downwardly convex hump, and both sides of the hump are curved arcs; under the action of the hump, the air blown out by the radiator fan 3 is guided by the hump at the bottom of the deflector 61, and the blown air can quickly flow to the heat dissipation fins 62, so as to achieve the purpose of rapid heat dissipation.
[0029] To facilitate the blowing out of heat, heat dissipation holes 7 are provided on both side walls of the housing 1, and each single hole of the heat dissipation holes 7 is located between the gaps of the heat dissipation fins 62; in this way, the air blown out from the gaps of the heat dissipation fins 62 can just blow out along the heat dissipation holes 7, reducing the blockage.
[0030] To facilitate the operation of the ABB frequency converter, control buttons 8 are provided on the front surface of the housing 1.
[0031] To avoid accidental touch of the control buttons 8, a cover plate 10 is rotatably connected to the front surface of the housing 1 through a damping rotating shaft 9, and the cover plate 10 covers the outside of the control buttons 8; when operating, open the cover plate 10, and when not operating, close the cover plate 10, and use the cover plate 10 to avoid accidental touch of the control buttons 8.
[0032] Embodiment 2:
[0033] When the ABB frequency converter has been used for a long time, a large amount of dust will adhere to the filter net 4, thus affecting the air intake and needing to be cleaned. At the same time, the radiator fan 3 also needs to be cleaned. Please refer to Figure 2 , on the basis of Embodiment 1, the baffle component 5 includes a baffle 51 slidably arranged at the bottom of the housing 1. Both ends of the baffle 51 are provided with strip-shaped holes, and positioning pins 52 fixedly connected to the housing 1 are arranged in the strip-shaped holes. Magnetic blocks 53 connected by magnetic attraction are embedded on both the baffle 51 and the housing 1, and a pull block 54 is fixedly arranged at the bottom of the baffle 51; after pulling down the baffle 51 through the pull block 54, the radiator fan 3 and the filter net 4 can be exposed, and then the radiator fan 3 and the filter net 4 can be horizontally pulled out for cleaning or replacement.
[0034] As can be seen from the above embodiments: when the ABB frequency converter is working, the radiator fan 3 starts, and the external air is filtered by the filter net 4 and then blown into the internal wind cavity. Since the heat conduction block 64 is in contact with the heating element, the heat generated when the heating element operates is transferred to the heat pipe 63 through the heat conduction block 64, and then transferred to the heat dissipation fins 62 on the deflector 61 through the heat pipe 63. Under the action of the deflector 61, the air blown out by the radiator fan 3 is guided by the hump at the bottom of the deflector 61, and the blown air can quickly flow to the heat dissipation fins 62 and gather on the heat dissipation fins 62, and then the heat can be quickly blown out from the heat dissipation holes 7 on both sides to achieve the purpose of rapid heat dissipation. When it is necessary to clean or replace the radiator fan 3 or the filter net 4, after pulling down the baffle 51 through the pull block 54, the radiator fan 3 and the filter net 4 can be exposed, and then the radiator fan 3 and the filter net 4 can be horizontally pulled out.
[0035] It should be noted that the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or apparatus including a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or apparatus.
[0036] 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 principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
