Description

Technical Field

[0001] This utility model relates to the field of air conditioner compressor technology, specifically to an air conditioner DC inverter compressor. Background Technology

[0002] A DC inverter compressor is a compression device installed in a DC inverter air conditioner. The DC inverter compressor generates a rotating magnetic field through the stator, which directly interacts with the permanent magnet magnetic field of the rotor to drive the operation. It adopts a voltage regulation and speed regulation method, which adjusts the speed by controlling the commutation frequency of the DC current in the three-phase winding of the motor. It belongs to a closed-loop control system and requires the detection of the rotor position for synchronous operation. Compared with AC inverter compressors, DC inverter compressors omit the inverter stage and directly output a DC power supply with variable voltage, resulting in higher efficiency.

[0003] Existing DC inverter compressors for air conditioners, such as the DC energy-saving inverter air conditioner electric compressor disclosed in publication number CN205370897U, have the advantages of high efficiency and low noise. However, during the lower compression operation of this compressor, the heat generated inside is not easily transferred and dissipated to the outside, resulting in poor heat dissipation. Therefore, we propose a DC inverter compressor for air conditioners. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] The following describes some embodiments of an air conditioning DC inverter compressor provided by the present invention with reference to the accompanying drawings.

[0025] Example 1:

[0026] Combination Figure 1-5 As shown, the present invention provides an air conditioner DC inverter compressor, comprising: a compressor housing 100 and a heat dissipation assembly 200; the compressor housing 100 includes a bottom fixing base 101 fixedly installed at its bottom, fixing ears 102 fixedly installed outside the bottom fixing base 101, and mounting holes 103 opened in each fixing ear 102; the heat dissipation assembly 200 includes movable seats 201 movably installed on the upper part of each fixing ear 102, heat conduction plates 202 fixedly installed on the upper end of each movable seat 201, multiple sets of heat dissipation fins 203 fixedly installed on the outer end of each heat conduction plate 202, and locking parts 204 reserved on the upper part of each heat conduction plate 202. The fastening part 204 has a movably installed locking clamp 205 and a movably installed locking bolt 206 on one side of the locking clamp 205. The movable seat 201 is also provided with a mounting groove 207, and the size of the mounting groove 207 is the same as the size of the mounting hole 103. The bottom of the movable seat 201 is also fixedly installed with a positioning block 208. The fixed ear 102 is also provided with a positioning groove 209, and the positioning groove 209 matches the positioning block 208. The outer end of the heat conduction plate 202 at the locking part 204 is fixedly installed with a protrusion 210. The locking clamp 205 is also provided with a bayonet 211, and the bayonet 211 matches the protrusion 210.

[0027] Specifically, the DC inverter compressor is a compression device installed inside a DC inverter air conditioner. After installation, the upper end of the fixed lug 102 of the DC inverter compressor in this air conditioner is attached to the fixed movable seat 201. The heat generated inside the compressor housing 100 during operation can be transferred through the heat-conducting plate 202 attached to the upper part of the lug 102 and the heat dissipation fins 203 arranged on the outer end of the heat-conducting plate 202. This transfers the heat to the multiple sets of heat dissipation fins 203 for rapid external heat dissipation, thereby effectively reducing the internal heat of the compressor during operation. To improve its service life, the locking clamp 205 installed at the upper locking part 204 of the heat-conducting plate 202 can also ensure a tight fit between the inner wall of the heat-conducting plate 202 and the compressor housing 100 by locking multiple sets of heat-conducting plates 202, thereby ensuring heat transfer efficiency. The fixing ear 102 at the bottom of the compressor housing 100 is mainly used to fix the compressor as a whole in the air conditioner body. The movable seat 201 can be installed on the upper part of the fixing ear 102 through the mounting groove 207 at the inner end, following the locking of the fixing ear 102. The movable seat 201 is also easily disassembled and reassembled, allowing for convenient installation, cleaning, and replacement. A locking bolt 206, movably mounted on one side of the locking clamp 205, is used to adjust the tightness of the clamp. A positioning block 208 is fixedly mounted at the bottom of the movable seat 201, and a positioning groove 209 is located inside the fixing ear 102. This facilitates the positioning and installation of the movable seat 201 on the upper end of the fixing ear 102, and also ensures the fixation of the movable seat 201 on the upper end of the fixing ear 102. Ensure that the upper heat-conducting plate 202 is tightly attached to the inside of the compressor housing 100. The heat-conducting plate 202 is positioned at the lower part of the compressor housing 100, so that it can be tightly attached to the compression working part at the lower part of the compressor housing 100, thereby concentrating the heat dissipation of the compression working part inside the compressor housing 100 and improving the heat dissipation effect. The protrusion 210 provided at the locking part 204 can match the bayonet 211 at its inner end after the locking clamp 205 is installed, thereby fixing the installation position of the locking clamp 205 at the locking part 204 and preventing it from falling off or tilting.

[0028] Working principle and usage process of this utility model:

[0029] When the compressor is installed inside the air conditioner unit, three sets of movable seats 201 are placed on the upper end of the fixed ears 102 in sequence, ensuring that the positioning blocks 208 at the bottom are matched and installed in the positioning grooves 209 inside the fixed ears 102. Then, they are locked and fixed inside the air conditioner unit with nuts, so that the heat conduction plate 202 on the upper part of the movable seat 201 is in contact with the outer wall of the compressor housing 100. At the same time, the locking clamp 205 installed on the upper part of the heat conduction plate 202 of the movable seat 201 can also ensure that multiple sets of heat conduction plates 202 are in close contact with the outer wall of the inner end of the compressor housing 100 after locking, so as to ensure the heat conduction effect during heat dissipation. When the compressor is working, the heat generated by the compressor in the lower part of the unit will be evenly transferred through the compressor housing 100 to the upper end of the heat conduction plate 202 and the heat dissipation fins 203 on the outer end, and heat dissipation will be carried out through the heat conduction plate 202 and the heat dissipation fins 203 to reduce the heat inside the compressor during operation, thereby improving its service life.
