Description

Technical Field

[0001] This application relates to the field of frequency converters, and more particularly to a partitioned enclosure for frequency converters. Background Technology

[0002] The inverters of large air conditioners contain a variety of high-current and high-heat-generating circuit components. If the arrangement of these circuit components is not reasonable, it will cause serious mutual interference, which will greatly reduce the reliability of the inverter. Utility Model Content

[0003] In order to reduce interference between the internal circuit components of the frequency converter, this application provides a partitioned enclosure for the frequency converter.

[0004] The partitioned enclosure for a frequency converter provided in this application adopts the following technical solution: A partitioned housing for a frequency converter includes a housing with two vertical partitions inside, which sequentially divide the interior of the housing into an air inlet zone, a working zone, and an air outlet zone. The working zone has multiple horizontal baffles that divide it into multiple chambers. The air inlet zone and the air outlet zone are both connected to the working zone. The housing has an air inlet that connects to the air inlet zone and an air outlet that connects to the air outlet zone.

[0005] By adopting the above technical solution, the outside air enters the air intake area through the air inlet, and then enters each chamber of the working area, carrying the heat in it into the air outlet area and exhausting it from the air outlet. The baffle can block the heat diffusion, and the circuit components in each chamber can be relatively independent, reducing the interference between the circuit components in different chambers and improving the stability of the frequency converter.

[0006] Optionally, the partition has multiple waist-shaped holes, and the working area is connected to the air inlet area or air outlet area through the waist-shaped holes. The baffle is provided with a connecting block that slides along the length of the waist-shaped holes, and a locking component is provided between the connecting block and the partition.

[0007] By adopting the above technical solution, the locking assembly is opened, the baffle can be moved, and the connecting block slides along the oblong hole, thereby adjusting the position of the baffle and controlling the size of each cavity. After the position of the baffle is determined, the locking assembly fixes the position of the baffle again.

[0008] Optionally, the baffle has a groove on its side wall facing the partition, and a connecting plate is slidably connected to the groove. One end of the connecting block is located in the groove and is slidably connected to the connecting plate along the length of the connecting plate.

[0009] Optionally, the locking assembly includes a rotating rod that is rotatably connected to the baffle, the end of the rotating rod passing through the connecting plate and threadedly connected to the connecting plate, and the locking assembly further includes a driving member for driving the rotating rod to rotate.

[0010] By adopting the above technical solution, the driving component drives the rotating rod to rotate, the rotating rod drives the connecting plate to slide, and the connecting plate drives the connecting block to move, thereby increasing the normal pressure between the connecting block and the partition and improving the friction between the connecting block and the partition, thereby fixing the position of the connecting block and the position of the baffle.

[0011] Optionally, the driving component includes a worm gear mounted on a rotating rod, and a worm gear meshing with all the worm gears is rotatably connected to the baffle plate. One end of the worm gear extends out of the baffle plate and is equipped with a knob.

[0012] By adopting the above technical solution, rotating the knob drives the worm gear to rotate, which in turn drives the worm wheel to rotate, thereby driving the rotating rod to rotate. The self-locking property of the worm wheel and worm gear prevents the baffle from moving when the worm gear stops.

[0013] Optionally, the waist-shaped hole is inclined on the partition.

[0014] By adopting the above technical solution, the inclined setting of the waist-shaped hole can reach a larger area within the cavity. During the ventilation and heat dissipation process, the heat can be quickly diffused into the entire cavity through the waist-shaped hole, thereby improving the heat dissipation efficiency.

[0015] Optionally, a baffle plate is provided in the air inlet area, the baffle plate is inclined and opposite to the air inlet.

[0016] By adopting the above technical solution, the wind deflector can block impurities in the airflow and reduce the amount of impurities entering the work area.

[0017] Optionally, a drying plate is provided on the wind deflector, and an insertion interface is provided on the housing, through which the wind deflector enters the housing.

[0018] By adopting the above technical solution, the drying sheet absorbs moisture in the airflow, thereby drying the airflow entering the working area and reducing the possibility of condensation in the working area.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. External air enters the air intake area through the air inlet, and then enters each chamber of the working area, carrying the heat into the air outlet area and exhausting it from the air outlet. The baffle can block the heat diffusion, and the circuit components in each chamber can be relatively independent, reducing the interference between the circuit components in different chambers and improving the stability of the frequency converter. 2. The inclined design of the waist-shaped holes can reach a larger area within the cavity. During ventilation and heat dissipation, the heat can be quickly diffused throughout the entire cavity through the waist-shaped holes, improving the efficiency of heat dissipation.

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] This application discloses a partitioned enclosure for a frequency converter.

[0026] Reference Figure 1 and Figure 2 A partitioned housing for a frequency converter includes a housing 1. Two vertical partitions 2 are fixedly connected inside the housing 1, dividing the interior of the housing 1 into three areas, namely an air inlet area 11, a working area 12, and an air outlet area 13. Two horizontal baffles 3 are provided between the two partitions 2, dividing the working area 12 into three chambers. The baffles 3 are movable relative to the partitions 2. The partitions 2 have multiple evenly distributed oblong holes 21, which are inclined in the vertical plane. The air inlet area 11 and the air outlet area 13 are both connected to the working area 12 through the oblong holes 21. The housing 1 has an air inlet that connects to the air inlet area 11 and an air outlet that connects to the air outlet area 13.

[0027] Outside air enters the air intake area 11 through the air inlet, and then enters each chamber of the working area 12 through the waist-shaped holes 21. The waist-shaped holes 21 are inclined so that they can reach a larger area within the cavity. During the ventilation and heat dissipation process, the air can quickly diffuse into the entire cavity through the waist-shaped holes 21, and carry the heat into the air outlet area 13 and out of the air outlet. The baffle 3 can block the heat diffusion. The circuit components in each chamber can be relatively independent, reducing the interference between the circuit components in different chambers.

[0028] Reference Figure 2 and Figure 3 A connecting block 4 is provided on the baffle 3 and slides along the length of the waist-shaped hole 21. A T-shaped groove is provided on the inner wall of the waist-shaped hole 21. The connecting block 4 is inserted into the groove and slides along the groove. A locking assembly 6 is provided between the connecting block 4 and the partition 2. A groove is provided on the side wall of the baffle 3 facing the partition 2. A connecting plate 5 is slidably connected to the groove. One end of the connecting block 4 is located in the groove and is slidably connected to the connecting plate 5 along the length of the connecting plate 5. The locking assembly 6 includes a rotating rod 61 that is rotatably connected to the baffle 3. The end of the rotating rod 61 passes through the connecting plate 5 and is threadedly connected to the connecting plate 5. The locking assembly 6 also includes a driving member that drives the rotating rod 61 to rotate.

[0029] The driving component drives the rotating rod 61 to rotate, which in turn drives the connecting plate 5 to slide. The connecting plate 5 then drives the connecting block 4 to move, thereby increasing the normal pressure between the connecting block 4 and the slide groove and increasing the friction between the connecting block 4 and the partition 2. This fixes the position of the connecting block 4 and the baffle 3. In the opposite direction, the rotating rod 61 is driven to rotate, reducing the friction of the connecting block 4 and allowing the locking assembly 6 to be opened. The baffle 3 can then be moved, and the connecting block 4 slides along the oblong hole 21. This allows the position of the baffle 3 to be adjusted, thereby controlling the size of each cavity. After the position of the baffle 3 is determined, the locking assembly 6 fixes the position of the baffle 3 again.

[0030] The driving component includes a worm gear 62 mounted on the rotating rod 61, and a worm 63 rotatably connected to the baffle 3, which meshes with all the worm gears 62. One end of the worm 63 extends out of the baffle 3 and is equipped with a knob. Rotating the knob causes the worm 63 to rotate, which in turn causes the worm gears 62 to rotate, thereby driving the rotating rod 61 to rotate. The self-locking property of the worm gears 62 and worm 63 prevents the baffle 3 from moving when the worm 63 stops.

[0031] Two parallel baffles 7 are installed in the air inlet area 11. The baffles 7 are inclined, with one baffle 7 facing the air inlet and the other located on the other side of the air inlet area 11. The two baffles 7 are staggered. Drying plates are installed on the baffles 7. An insertion interface is provided on the housing 1, through which the baffles 7 enter the housing 1. The baffles 7 can block impurities in the airflow, and the drying plates absorb moisture in the airflow, thus drying the airflow entering the working area 12 and reducing the possibility of condensation in the working area 12.

[0032] The implementation principle of a partitioned housing for a frequency converter in this embodiment is as follows: rotating the knob drives the worm gear 63 to rotate, which in turn drives the worm wheel 62 and the rotating rod 61 to rotate, thereby controlling the friction between the connecting block 4 and the partition 2, thereby controlling whether the baffle 3 is locked. When the baffle 3 is not locked, the position of the baffle 3 is adjusted. After the position of the baffle 3 is determined, the locking assembly 6 locks the baffle 3 again. The external airflow enters the air inlet area 11 through the air inlet, passes through the gap between the two baffles 7, and then enters the cavity through the waist-shaped hole 21, and enters the air outlet area 13 through the waist-shaped hole 21 on the other side, until it is discharged.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
