Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1 to 3, the utility model provides an air-cooled frequency conversion all-in-one machine, which comprises a frequency converter 1 and a motor 2.
The housing 11 of the frequency converter 1 is connected to the housing 21 of the electric motor 2 via a connecting arm 3, the connecting arm 3 separates the frequency converter 1 from the electric motor 2, and the space formed between the two serves as a heat dissipation channel 4.
A radiating fin 5 is arranged on the frequency converter 1, and the radiating fin 5 is positioned at the rear end of the shell 11.
The first fan 71 is mounted at the rear end of the main shaft of the motor 2, the hood 6 is mounted at the rear end of the housing 21 of the motor 2, and the first fan 71 is positioned in the hood 6.
The front end of the hood 6 is sleeved on the shell 21, and the rear end is provided with an air inlet 61.
The first fan 71 rotates along with the main shaft of the motor 2, sucks external air into the housing 6 through the air inlet 61, and blows the air after being concentrated in the housing 6 toward the motor 2 to dissipate heat of the motor 2.
The heat sink 5 is located above the hood 6, and includes two panels 51 arranged in parallel and at an interval, a partition plate 52 is arranged between the two panels 51, two ends of the partition plate 52 are respectively connected with the corresponding panels 51, and the partition plate 52 is arranged at intervals.
The two panels 51 and the two adjacent partitions 52 form a space through which air can flow, so that the air can pass through the inside of the heat sink 5, thereby taking away heat from the heat sink 5 and improving heat dissipation effect.
A panel 51 of the heat sink 5 is fixed on the side plate 12 at the rear side of the housing 11, so as to contact with the housing 11, thereby increasing the contact area, increasing the heat transfer speed, and rapidly transferring the heat on the frequency converter to the heat sink 5, thereby increasing the heat dissipation speed. In addition, the air flowing space is vertically arranged, so that high-temperature gas can easily rise and leave the air flowing space, and the heat dissipation in the radiating fins 5 is accelerated.
In order to accelerate the heat dissipation, the second fan 72 is installed on the heat sink 5 to send air to the heat sink 5, thereby accelerating the heat dissipation from the heat sink 5.
To further increase the heat dissipation speed, a second fan 72 is installed at the bottom end of the heat sink 5 to align with the opening of the air flowing space in the heat sink 5, and sends air into the heat sink 5 to increase the heat removal. In addition, the second fan 72 can suck air in the heat dissipation channel 4, thereby taking away heat in the heat dissipation channel 4 and improving the heat dissipation effect.
The first fan 71 sucks air at the rear side of the equipment to axially flow, one part of the air enters the hood 6 and blows towards the motor 2, the other part of the air flows along the outer wall of the hood 6 and flows into the heat dissipation channel 4, and heat dissipated to the heat dissipation channel 4 by the frequency converter 1 and the motor 2 is taken away, so that the inside of the equipment has high air circulation and the heat dissipation effect is enhanced.
The heat dissipation channel 4 separates the frequency converter 1 from the motor 2, weakens heat transfer between the frequency converter and the motor, and avoids the over-high temperature of the whole equipment.
The air sucked into the hood 6 by the first fan 71 flows out through the hook grooves provided in the housing 21 and flows along the outer wall of the motor 2, taking heat of the motor 2 away. Meanwhile, a part of air flowing along the outer wall of the motor 2 enters the heat dissipation channel 4 and takes away high-temperature air in the heat dissipation channel 4.
The height position of second fan 72 is higher than the bottom surface of casing 11, and the bottom surface of second fan 72 is higher than the casing 11 bottom surface promptly, prevents that second fan 72 from protruding downwards for the casing 11 bottom surface, and the air that flows out to heat dissipation channel 4 forms and blocks, makes the high temperature air in heat dissipation channel 4 can be more quick and smooth outflow, improves the radiating efficiency.
The top surface of the hood 6 is flush with the top surface of the housing 21, so that air flowing against the outer wall of the hood 6 can smoothly flow into the heat dissipation channel 4 and take away high-temperature air in the heat dissipation channel 4.
The IGBT module that converter 1 set up calorific capacity is great, and the IGBT module is installed on the curb plate 12 of casing 11 rear side, and the heat of production can directly transmit for fin 5 through curb plate 12, shortens the route of heat transfer for the radiating rate.
