Technical Field

[0001] This utility model relates to the field of compressors, and in particular to a compressor frequency conversion control device. Background Technology

[0002] A compressor is a mechanical device that compresses gas to increase its pressure. Its working principle is to mechanically reduce the volume of gas, thereby increasing its pressure. During compressor operation, a frequency converter is typically used to regulate the operating frequency of the compressor motor.

[0003] As shown in the patent document with publication number CN220822878U, the rectifier module and inverter module can effectively dissipate heat to the outside through the heat dissipation substrate, eliminating the need to install a cooling fan inside the housing, thereby further reducing the size of the housing.

[0004] During compressor operation, heat dissipation can improve the compressor's operating efficiency and safety performance. While heat dissipation through heat sinks reduces the size of the casing, if the air inside the casing is not circulating or the airflow is slow, local overheating may occur, thus affecting the heat dissipation effect.

[0005] Therefore, it is necessary to provide a compressor frequency converter control device to solve the above-mentioned technical problems. Utility Model Content

[0008] Preferably, the heat dissipation substrate includes a rectangular plate, the mounting port is opened on the upper surface of the rectangular plate, the interior of the rectangular plate is provided with a storage groove communicating with the mounting port, the upper surface of the rectangular plate is provided with an air inlet and an air outlet communicating with the storage groove, the mounting port is located between the air inlet and the air outlet, the interior of the air inlet is provided with an inspection cover, and the upper surface of the heat dissipation fan is fixedly connected to the lower surface of the inspection cover.

[0009] Preferably, the inspection cover includes a rectangular mounting frame located inside the air inlet, the upper surface of the cooling fan is fixedly connected to the lower surface of the rectangular mounting frame, and a filter screen is fixedly connected to the inner wall of the rectangular mounting frame.

[0013] Compared with related technologies, the compressor frequency converter control device provided by this utility model has the following beneficial effects:

[0014] 1. The compressor frequency converter control device has a heat dissipation base plate that restricts the installation position of the compressor frequency converter. The installation port restricts the installation position of the heat conduction plate on the heat dissipation base plate. The heat conduction plate restricts the installation position of several heat dissipation fins. The heat conduction plate can conduct the heat dissipated by the compressor frequency converter to several heat dissipation fins. Several heat dissipation fins can increase the heat dissipation area. Starting the cooling fan can remove the hot air around several heat dissipation fins, thereby improving the overall heat dissipation efficiency and keeping the compressor frequency converter operating within a safe temperature range. This can minimize the occurrence of local overheating of the compressor frequency converter due to poor air circulation or slow air circulation inside the mounting housing of the compressor frequency converter control device.

[0015] 2. The compressor frequency converter control device, through the opening of the storage slot, can restrict the installation position of the heat dissipation fins and the heat dissipation fan. When the heat dissipation fan starts, air can enter into the storage slot through the air inlet, and the air outlet can exhaust the hot air inside the storage slot to the outside, so that the air can circulate and dissipate heat from the heat dissipation fins. The maintenance cover can restrict the installation position of the heat dissipation fan, and the maintenance cover can be opened and closed as needed, so as to facilitate personnel to maintain the heat dissipation fan. The rectangular mounting frame can restrict the installation position of the heat dissipation fan and the filter screen, and the filter screen can perform a certain degree of filtration on the circulating air.

[0016] 3. The compressor frequency converter control device is equipped with an L-shaped air guide plate to guide the air discharged through the exhaust port to prevent hot air from flowing back to the air inlet. Multiple support columns can support the drive plate on top of the rectangular plate. The drive plate is used to install the power supply, compressor wiring terminals and other structures. The wing bolts can restrict the connection position between the drive plate and the support columns, thereby reinforcing the installation position of the drive plate. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 5 A compressor frequency converter control device includes: a heat dissipation base plate 1, a compressor frequency converter 2 fixedly connected to the upper surface of the heat dissipation base plate 1, an installation port 3 on the heat dissipation base plate 1, a heat conduction plate 4 disposed inside the installation port 3, the heat conduction plate 4 being located on the lower surface of the compressor frequency converter 2, a plurality of heat dissipation fins 5 being disposed, the plurality of heat dissipation fins 5 being evenly fixedly disposed on the lower surface of the heat conduction plate 4, and a heat dissipation fan 6 being disposed on the top of the inner wall of the heat dissipation base plate 1, the heat dissipation fan 6 being located on one side of the plurality of heat dissipation fins 5.

[0025] In practical implementation, the heat dissipation base plate 1 in the compressor frequency converter control device restricts the installation position of the compressor frequency converter 2. The compressor frequency converter 2 mainly consists of a rectification, filtering, inversion, braking unit, drive unit, detection unit, and microprocessor unit. The compressor frequency converter 2 can adjust the frequency and voltage of the motor input power supply, thereby achieving precise control of the compressor speed. This allows for flexible adjustment of the compressor's operating state according to load requirements, improving energy efficiency, reducing noise, and extending equipment life. The installation port 3 restricts the installation position of the heat conduction plate 4 on the heat dissipation base plate 1. The heat conduction plate 4 can be made of pure aluminum or copper and is located on the lower surface of the compressor frequency converter 2. Thus, the heat conduction plate 4 can dissipate the heat from the compressor frequency converter 2. The dissipated heat is conducted to several heat dissipation fins 5. These fins 5 can be designed in a wave shape. By setting several heat dissipation fins 5, the heat dissipation area can be increased, and the heat exchange efficiency between hot air and heat dissipation fins 5 can be improved. Furthermore, a cooling fan 6 is set on the top of the inner wall of the heat dissipation base plate 1 and is located on one side of several heat dissipation fins 5. Specifically, by starting the cooling fan 6, the hot air around several heat dissipation fins 5 can be removed, thereby improving the overall heat dissipation efficiency and keeping the compressor inverter 2 operating within a safe temperature range. This can minimize the occurrence of local overheating of the compressor inverter 2 due to poor air circulation or slow air circulation inside the mounting housing of the compressor inverter control device, thereby improving the heat dissipation effect of this compressor inverter control device.

[0026] refer to Figure 2 , Figure 3 and Figure 4 As shown, the heat dissipation substrate 1 includes a rectangular plate 101, with a mounting port 3 on the upper surface of the rectangular plate 101. The rectangular plate 101 has a storage slot 102 connected to the mounting port 3 inside. The upper surface of the rectangular plate 101 has an air inlet 103 and an air outlet 104 connected to the storage slot 102. The mounting port 3 is located between the air inlet 103 and the air outlet 104. An inspection cover 105 is provided inside the air inlet 103. The upper surface of the heat dissipation fan 6 is fixedly connected to the lower surface of the inspection cover 105.

[0027] In the specific implementation process, the storage slot 102 can restrict the installation position of the heat dissipation fins 5 and the heat dissipation fan 6. When the heat dissipation fan 6 is started, air can enter the interior of the storage slot 102 through the air inlet 103, and the hot air inside the storage slot 102 can be discharged to the outside through the air outlet 104, so that the air can circulate to dissipate heat from the heat dissipation fins 5. The maintenance cover 105 can restrict the installation position of the heat dissipation fan 6, and the maintenance cover 105 can be opened and closed as needed, so as to facilitate personnel to maintain the heat dissipation fan 6.

[0028] refer to Figure 2 , Figure 3 and Figure 4 As shown, the inspection cover 105 includes a rectangular mounting frame 1051 located inside the air inlet 103. The upper surface of the cooling fan 6 is fixedly connected to the lower surface of the rectangular mounting frame 1051, and a filter screen 1052 is fixedly connected to the inner wall of the rectangular mounting frame 1051.

[0029] In the specific implementation process, the rectangular mounting frame 1051 can restrict the installation position of the cooling fan 6 and the filter screen 1052. When the cooling fan 6 is started, the filter screen 1052 can perform certain filtration treatment on the circulating air.

[0030] refer to Figure 2 and Figure 5 As shown, an L-shaped air guide plate 7 is fixedly connected to the upper surface of the rectangular plate 101, and the L-shaped air guide plate 7 is located above the exhaust port 104.

[0031] In the specific implementation process, the L-shaped air guide plate 7 can guide the air discharged through the exhaust port 104 to prevent hot air from flowing back to the air inlet 103.

[0032] refer to Figure 1 and Figure 2 As shown, a plurality of support columns 8 are uniformly fixedly connected to the upper surface of the rectangular plate 101, and a drive plate 9 located on the upper end face of the plurality of support columns 8 is provided above the rectangular plate 101.

[0033] In the specific implementation process, the drive plate 9 can be supported and installed on the rectangular plate 101 by multiple support columns 8. The drive plate 9 is used to install power supply, compressor wiring terminals and other structures.

[0034] refer to Figure 1 and Figure 2 As shown, multiple wing bolts 10 are evenly rotatably connected to the drive plate 9, and the outer wall of the bottom end of each wing bolt 10 is threadedly connected to the inner wall of each support column 8.

[0035] In the specific implementation process, the connection position between the drive plate 9 and the support column 8 can be restricted by the wing bolt 10, thereby reinforcing the installation position of the drive plate 9. The connection method of installation by the wing bolt 10 also makes it easy for personnel to disassemble the drive plate 9.

[0036] The working principle of the compressor frequency conversion control device provided by this utility model is as follows:

[0037] In use, the compressor inverter 2 is mounted on the heat dissipation base plate 1, and several heat dissipation fins 5 are mounted inside the heat dissipation base plate 1 through a heat conduction plate 4, with the heat conduction plate 4 located on the lower surface of the compressor inverter 2. The heat dissipation plate 4 conducts the heat emitted by the compressor inverter 2 to the heat dissipation fins 5, thereby increasing the heat dissipation area and improving the heat exchange efficiency between the hot air and the heat dissipation fins 5. The cooling fan 6 is set at the top of the inner wall of the heat dissipation base plate 1 and located on one side of the heat dissipation fins 5. Activating the cooling fan 6 can remove the hot air around the heat dissipation fins 5, thereby improving the overall heat dissipation efficiency and keeping the compressor inverter 2 operating within a safe temperature range. This can minimize the occurrence of localized overheating of the compressor inverter 2 due to poor or slow air circulation inside the mounting housing of the compressor inverter control device, thus improving the heat dissipation effect of the compressor inverter control device.
