Technical Field

[0002] An air conditioner is a device used to regulate indoor temperature, humidity, and air cleanliness. A three-phase electrolytic capacitor-free air conditioner refers to an air conditioning system that uses a three-phase power supply and eliminates traditional electrolytic capacitors in its circuit design. Electrolytic capacitors in traditional air conditioners are mainly used to smooth DC voltage fluctuations, but they have disadvantages such as short lifespan and susceptibility to temperature changes. Removing electrolytic capacitors can improve system reliability and extend service life, while reducing maintenance requirements.
[0003] Based on the above, the inventors have discovered the following problems: Current frequency converters are prone to generating heat during use. If the heat is not dissipated in time, it can lead to a decline in performance. Furthermore, high-temperature environments can accelerate the aging process and shorten their service life. Traditional heat dissipation ducts are ineffective and inconvenient to use.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a three-phase electrolysis-free air conditioning inverter module heat dissipation duct structure in order to achieve a more practical purpose. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figures 1-5This utility model provides a technical solution: a heat dissipation air duct structure for a three-phase electrolysis-free air conditioning inverter module, including an air supply component 101, with a heat dissipation component 102 on one side of the air supply component 101. The presence of the heat dissipation component 102 on one side of the air supply component 101 facilitates the airflow generated by the air supply component 101 entering the heat dissipation component 102, allowing the air to accelerate through the heat dissipation component 102 and carry away heat. The heat dissipation component 102 includes an air inlet section 10201, one end of which is connected to the air supply component. The output end of 101 is fixedly connected, and the other end of the air inlet section 10201 is connected to the heat dissipation section 10202. The width of the air inlet section 10201 gradually increases as it approaches the heat dissipation section 10202. This gradual increase in width facilitates the acceleration of the airflow generated by the air supply component 101 within the air inlet section 10201, allowing the airflow to flow at high speed through the heat dissipation section 10202. A mounting hole 10205 is provided on one side of the heat dissipation section 10202. The design facilitates the fixed installation of the heat absorber plate 10206. The heat absorber plate 10206 is fixedly installed inside the mounting hole 10205, and a heat sink 10207 is fixedly installed on one side of the heat absorber plate 10206. The heat sink 10207 is located inside the heat dissipation section 10202. The fixed installation of the heat sink 10207 on one side of the heat absorber plate 10206 and its placement inside the heat dissipation section 10202 facilitates the absorption of heat by the heat absorber plate 10206 and its transfer to the heat sink 10207. The heat sink 10207 increases the heat dissipation area and improves the heat dissipation effect, allowing high-speed airflow to blow across the surface of the heat sink 10207 and carry away heat, thereby achieving the function of heat dissipation and cooling. A thermally conductive silicone pad 10208 is fixedly installed on the other side of the heat sink 10207. The thermally conductive silicone pad 10208 fills the gap between the frequency converter module and the heat sink 10207, achieving efficient heat transfer and also playing a role in electrical insulation.

With the phase change fluid and the capillary layer 10209, the phase change fluid can absorb heat and vaporize inside the heat absorber plate 10206 and flow into the heat sink 10207. The vaporized phase change fluid inside the heat sink 10207 dissipates heat and liquefies. The liquefied phase change fluid is drawn into the heat absorber plate 10206 by the capillary layer 10209, thereby improving the heat conduction efficiency of the heat absorber plate 10206 to the heat sink 10207.

[0036] The volute 10101 has an air inlet 10102 on one side, and a filter 10109 is installed inside the air inlet 10102. The filter 10109 inside the air inlet 10102 facilitates the intake of external air into the volute 10101, and the filter 10109 filters the air to prevent dust from entering the device and affecting the heat dissipation effect.
[0037] The volute 10101 has an air outlet 10103 on the other side, which is connected to one end of the air inlet section 10201. The air outlet 10103 is connected to one end of the air inlet section 10201, so that the airflow generated inside the volute 10101 can enter the heat dissipation component 102 from the air outlet 10103.

The fixed connection between the output end of the drive motor 10105 and the impeller 10104 facilitates the operation of the drive motor 10105 to drive the impeller 10104 to rotate.
[0039] The air outlet 10103 has an installation groove 10107 on its inner side. The inner side of the installation groove 10107 is slidably connected to the filter 10109. The slidable connection between the inner side of the installation groove 10107 and the filter 10109 facilitates the provision of an installation position for the filter 10109 inside the air outlet 10103.
[0040] The mounting groove 10107 has a fixed slot 10108 at the top, and the filter element 10109 has an mounting strip 10110 fixedly installed on the top. The mounting strip 10110 is engaged with the fixed slot 10108. The engagement of the mounting strip 10110 with the fixed slot 10108 facilitates the fixed installation of the filter element 10109 and allows for easy disassembly and replacement of the filter element 10109.
[0041] Specifically, the working principle of this three-phase electrolysis-free air conditioning inverter module heat dissipation duct structure is as follows: During use, the filter 10109 is slidably connected to the inner side of the mounting groove 10107, facilitating the provision of an installation position for the filter 10109 inside the air outlet 10103.
