Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioner controller technology, specifically to an air-cooled inverter energy-saving controller for air conditioners. Background Technology
[0002] In existing technologies, an air-cooled inverter energy-saving controller is an electronic device specifically designed to control and optimize air-cooled air conditioning systems. It is commonly found in household, commercial, and some industrial air conditioning systems. Its core function is to adjust the operating speed of the air conditioning compressor through inverter technology, thereby achieving more efficient and energy-saving temperature control.
[0003] In the existing technology, during the operation of the device, the controller continuously generates heat and the temperature rises continuously. It mainly relies on the heat sink installed on the surface of the device for passive heat dissipation. However, under long-term high-load working conditions, the heat dissipation efficiency of the traditional heat dissipation method drops significantly, making it difficult to effectively dissipate the accumulated heat. This can easily lead to the controller overheating. To prevent damage to components, the system will trigger a thermal protection mechanism, which will force a reduction in output power, thereby affecting the frequency conversion regulation performance. Utility Model Content
[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides an air-cooled inverter energy-saving controller for air conditioning. Through a serpentine channel, it guides the coolant to flow evenly and fully through areas of concentrated heat generation, significantly reducing the operating temperature of key components and preventing localized overheating. This effectively solves the problem of passive heat dissipation, which in existing technologies mainly relies on heat sinks installed on the surface of the device.
[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides an air-cooled inverter energy-saving controller for air conditioning, including a control panel. The control panel is provided with a circulating heat dissipation mechanism, which includes a serpentine groove, a liquid inlet, and a liquid outlet. The serpentine groove is opened inside the control panel, and the two liquid inlets and liquid outlets are respectively fixedly connected to the two side walls of the control panel. The liquid inlet, the serpentine groove, and the liquid outlet are connected in sequence.
[0006] Furthermore, two flanges are fixedly connected to the circumferential surfaces of both liquid inlets and outlets.
[0007] Furthermore, two first heat sinks are fixedly connected to the upper end of the control panel, and a second heat sink is fixedly connected to the upper end of the control panel.
[0008] Furthermore, multiple controllers are fixedly connected to the upper part of each control panel.
[0009] Furthermore, the upper end of the control panel is fixedly connected to multiple first interfaces, multiple second interfaces, and a third interface.
[0010] Furthermore, the diameter and width of the serpentine groove are set to 25–40 mm.
[0011] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. Coolant enters through the inlet and flows into a serpentine channel inside the control panel. Following the winding path of the serpentine channel, it flows past the area near the heat-generating elements within the control panel. Through heat conduction with the control panel material, it carries away internal heat. After heat exchange, the coolant continues to flow to the outlet and is discharged, achieving a continuous liquid circulation and heat dissipation process. This structure extends the flow path and residence time of the coolant within the control panel through the serpentine channel, increasing the heat dissipation contact area and efficiency. The inlet and outlet are located at the same end of the control panel, facilitating centralized connection of external pipelines and system integration, reducing installation space and leakage risks, while ensuring directional flow of the coolant and maintaining circulation stability.
[0012] 2. By bolting the flanges to the corresponding flanges at the ends of the external pipelines, a detachable sealed connection is achieved between the liquid inlet and the external liquid supply pipeline, and between the liquid outlet and the external liquid return pipeline. This allows the cooling medium to flow into the serpentine channel through the liquid inlet and out through the liquid outlet, forming a circulation channel. The two flanges are respectively set at the connection ends of the liquid inlet and the liquid outlet to ensure the alignment and structural stability of the connection interface, prevent the pipeline from loosening or leaking due to vibration or thermal expansion and contraction, and facilitate installation, disassembly and subsequent maintenance.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0017] The present invention will be further described below with reference to the embodiments.
[0018] See attached document Figure 1 - Figure 4 An air-cooled inverter energy-saving controller for air conditioning includes a control panel 1. The control panel 1 is provided with a circulating heat dissipation mechanism, which includes a serpentine groove 2, a liquid inlet 3, and a liquid outlet 4. The serpentine groove 2 is opened in the control panel 1. The two liquid inlets 3 and the liquid outlet 4 are respectively fixedly connected to the two side walls of the control panel 1. The liquid inlet 3, the serpentine groove 2, and the liquid outlet 4 are connected in sequence.
[0019] In a specific embodiment of this utility model, the coolant enters from the inlet 3 and flows into the serpentine channel 2 inside the control panel 1. It extends along the curved channel of the serpentine channel 2 through the area near the heating element inside the control panel 1, and carries away the internal heat through thermal conduction with the material of the control panel 1. After completing the heat exchange, the coolant continues to flow to the outlet 4 and is discharged, realizing a continuous liquid circulation heat dissipation process. This structure extends the flow path and residence time of the coolant in the control panel 1 through the serpentine channel 2, thereby improving the heat dissipation contact area and efficiency. The arrangement of the inlet 3 and the outlet 4 at the same end of the control panel 1 facilitates centralized connection of external pipelines and system integration, reduces installation space and leakage risk, and ensures directional flow of coolant to maintain circulation stability.
[0020] For details, please refer to the attached document. Figure 1 - Figure 4 Two flanges 5 are fixedly connected to the circumferential surfaces of the two liquid inlets 3 and the liquid outlet 4.
[0021] In this embodiment: the flange 5 is bolted to the corresponding flange at the end of the external pipeline to achieve a detachable sealed connection between the liquid inlet 3 and the external liquid supply pipeline and the liquid outlet 4 and the external liquid return pipeline. This allows the cooling medium to flow into the serpentine channel 2 through the liquid inlet 3 and out through the liquid outlet 4, forming a circulation channel. The two flanges 5 are respectively set at the connection ends of the liquid inlet 3 and the liquid outlet 4 to ensure the alignment and structural stability of the connection interface, prevent the pipeline from loosening or leaking due to vibration or thermal expansion and contraction, and facilitate installation, disassembly and subsequent maintenance.
[0022] For details, please refer to the attached document. Figure 1 - Figure 4 Two first heat sinks 6 are fixedly connected to the upper end of the control panel 1, and a second heat sink 7 is fixedly connected to the upper end of the control panel 1.
[0023] In this embodiment: through the direct contact between the two first heat sinks 6 and the second heat sink 7 and the surface of the control panel 1, the heat generated by the internal electronic components of the control panel 1 during operation is conducted to the fin structure of the first heat sink 6 and the second heat sink 7. Natural air convection or forced airflow from an external fan passes over the surface of the first heat sink 6 and the second heat sink 7, increasing the heat dissipation area to accelerate the dissipation of heat to the surrounding environment.
[0024] For details, please refer to the attached document. Figure 1 - Figure 4 Multiple controllers 8 are fixedly connected to the upper part of the control panel 1.
[0025] In this embodiment: through the electrical and mechanical connection between multiple controllers 8 and control panel 1, signal processing, frequency adjustment and power control of the air conditioner's variable frequency operation are realized. The heat generated by the controller 8 during operation is conducted through its contact surface with control panel 1 to the serpentine groove 2 inside control panel 1 and the first heat sink 6 and the second heat sink 7. Control panel 1, as the structural base, provides installation positioning and heat conduction path for multiple controllers 8, so that the controllers 8 are centrally arranged at the top of control panel 1, which facilitates their coordinated work with the heat dissipation structure. At the same time, through the internal circuit of control panel 1, multiple controllers 8 are electrically connected to realize the unified transmission of signals and power.
[0026] For details, please refer to the attached document. Figure 1 - Figure 4 The upper part of the control panel 1 is fixedly connected to multiple first interfaces 9, the upper part of the control panel 1 is fixedly connected to multiple second interfaces 10, and the upper part of the control panel 1 is fixedly connected to a third interface 11.
[0027] In this embodiment: multiple first interfaces 9 are used to achieve electrical connection with sensors or external control signal lines in the air conditioning system; multiple second interfaces 10 are used to connect the signal transmission lines of actuators or frequency converter drive modules; and a third interface 11 is used to connect to the power supply line or communication bus. The first interfaces 9, second interfaces 10 and third interfaces 11 are respectively plugged into and fixed to the connection terminals of the corresponding external devices, so that the control panel 1 establishes electrical connection with various functional components of the air conditioning system through multiple first interfaces 9, second interfaces 10 and third interfaces 11, and completes the input and output transmission of control signals, feedback signals and power.
[0028] For details, please refer to the attached document. Figure 1 - Figure 4 The diameter and width of the serpentine groove 2 are set to 25-40 mm.
[0029] In this embodiment, the diameter and width of the serpentine channel 2 are set to 25-40 mm. The cooling medium enters through the liquid inlet 3 and flows along a curved path in the serpentine channel 2 opened inside the control panel 1. This width range allows the serpentine channel 2 to maintain a sufficient flow cross-sectional area in a limited space, ensuring stable cooling medium flow and reducing flow resistance.
[0030] The working principle and usage process of this utility model are as follows: The external coolant supply pipeline is connected to the inlet 3 via flange 5, and the return pipeline is connected to the outlet 4 via flange 5. The coolant enters the serpentine channel 2 inside the control panel 1 from the inlet 3. It flows along the curved channel in the serpentine channel 2, which is 25-40mm wide, absorbing the heat generated by the operation of multiple controllers 8 inside the control panel 1. After heat exchange, the coolant is discharged from the outlet 4, forming a circulating heat dissipation. The multiple controllers 8 are connected to the sensors, actuators and power supply of the air conditioning system through the first interface 9, the second interface 10 and the third interface 11, respectively. The control panel 1 processes signals and adjusts the frequency converter output through the controllers 8. The heat is simultaneously conducted through the control panel 1 to the two first heat sinks 6 and the second heat sink 7, and further dissipated by air convection. This utility model can guide the coolant to flow evenly and fully through the heat concentration area through the serpentine channel, significantly reducing the working temperature of key components, avoiding local overheating, achieving effective heat dissipation, reducing thermal stress, preventing program disorder, signal drift or malfunction caused by high temperature, and improving the overall stability of the controller.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
