Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. To better illustrate the present invention, numerous specific details are provided in the following detailed description. Those skilled in the art should understand that the present invention can be implemented even without certain specific details.

[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Please see Figures 1 to 3 This utility model provides an electronic control device for an air conditioner, which includes a radiator 100, a sealing bracket 200, and a circuit board 300.

[0033] Among them, the circuit board 300, as the main structure of the electronic control device, carries various electronic components 310 that control the operation of the air conditioner control system, such as integrated circuits, capacitors, resistors, relays, etc.

[0034] The heat sink 100 is positioned above the circuit board 300 and connected to the circuit board 300 via a sealing bracket 200. This design facilitates the natural upward transfer of heat emitted from the circuit board 300 to the heat sink 100, thereby improving heat dissipation efficiency. Simultaneously, placing the heat sink 100 above the circuit board 300 provides some protection for the circuit board 300 below, reducing direct interference from external factors.

[0035] The sealing bracket 200 has a side circumference 230, and the side circumference 230 has a first edge and a second edge disposed opposite to each other in the vertical direction. The first edge is sealed to the surface of the heat sink 100, and the second edge is sealed to the surface of the circuit board 300, thereby enclosing an internal space with the side circumference 230.

[0036] like Figure 1 As shown, the arrow Y points in the vertical direction, and the arrow X points in the horizontal direction perpendicular to the vertical direction. That is, the side panel 230 is hollow in the vertical direction. The first edge is the top edge of the side panel 230, and the second edge is the bottom edge of the side panel 230. The top edge of the side panel 230 is sealed to the lower surface of the heat sink 100, and the bottom edge of the side panel 230 is sealed to the upper surface of the circuit board 300. Therefore, the heat sink 100 located above, the circuit board 300 located below, and the sealing bracket 200 connecting the two can together enclose a cavity-shaped internal space.

[0037] Based on the above structure, the side enclosure 230 is provided with a first ventilation opening 210 connecting the internal space and the external space. The main function of the first ventilation opening 210 is to allow air circulation between the internal space and the external space, and to remove heat from the inside of the sealed bracket 200 through natural convection. This helps the electronic components 310 located in the internal space to operate within a safe temperature range, preventing overheating that could lead to performance degradation or malfunction of the electronic components 310.

[0038] Furthermore, in some applications, the interior of the sealing bracket 200 may experience a pressure difference due to temperature changes, gas generation, or external pressure variations. The first vent 210 can serve as a pressure relief channel, helping to balance the internal and external pressures and preventing damage to the sealing bracket 200 due to excessive pressure.

[0039] Furthermore, in this embodiment, the height of the first vent 210 is less than the length of the first vent 210, that is, the outline shape of the first vent 210 in the vertical direction is elongated.

[0040] Although the height of the first vent 210 is relatively small, its length is relatively long. This helps to ensure the surface area of ​​the first vent 210 in contact with the outside air, thereby ensuring its heat dissipation effect. Moreover, because the height of the first vent 210 is small, insects cannot pass through directly, forming a natural physical barrier and reducing the possibility of insects entering the sealed support 200.

[0041] Specifically, such as Figure 1 As shown, the dimension H of the first ventilation opening 210 along the vertical direction (i.e., the Y direction) is the height of the first ventilation opening 210, and the dimension L of the first ventilation opening 210 along the horizontal direction (i.e., the X direction) is the length of the first ventilation opening 210. The value of the height H is much smaller than the value of the length L.

[0042] The height of the first ventilation opening 210 is 0.9mm to 1.1mm, and for example, the height of the first ventilation opening 210 is 1mm. The length of the first ventilation opening 210 is 9.9mm to 10.1mm, and for example, the length of the first ventilation opening 210 is 10mm.

[0043] The first vent 210 with the above-mentioned dimensions ensures sufficient heat dissipation area while effectively preventing insects by reducing the height of the first vent 210. This design not only meets the heat dissipation requirements of the sealing bracket 200 but also improves the protective performance of the sealing bracket 200.

[0044] like Figure 1 and Figure 3 As shown, there are multiple first ventilation openings 210, and a reinforcing member 240 is provided between two adjacent first ventilation openings 210. By providing the reinforcing member 240, the structural strength between two adjacent first ventilation openings 210 can be increased, preventing local weakening of the sealing bracket 200 caused by cutting the first ventilation opening 210. It can effectively resist external loads and vibrations, and ensure the overall stability and safety of the sealing bracket 200.

[0045] In this embodiment, the reinforcing member 240 and the sealing bracket 200 are integrally formed. The integrally formed design means that there are no seams or connection points between the reinforcing member 240 and the sealing bracket 200, thereby reducing structural weaknesses caused by poor connections. This design makes the entire structure more robust and stable, better able to resist external loads and vibrations, and ensures the integrity and reliability of the sealing bracket 200.

[0046] Please see Figure 3The cross-sectional dimension of the reinforcing member 240 is greater than the thickness of the side circumference 230, meaning that at least the thickness of the cross-section of the reinforcing member 240 is greater than the thickness of the side circumference 230. The larger cross-sectional dimension means that the reinforcing member 240 has a larger cross-sectional area, thereby providing stronger bending and shear resistance, which helps to resist external loads and vibrations and ensures the stability and safety of the sealing bracket 200 and its internal components.

[0047] Based on the design of integrally molding the reinforcing member 240 and the sealing bracket 200, the reinforcing member 240 can be configured to extend into the side wall 230 or protrude outward from the side wall 230, or simultaneously extend into the side wall 230 and protrude outward from the side wall 230. This design allows the thickness of the reinforcing member 240 to exceed the thickness of the side wall 230, thereby achieving the purpose of enhancing the structural strength.

[0048] In this embodiment, when the circuit board 300 is connected to the sealing bracket 200, the electronic components 310 on the circuit board 300 are located within the internal space. Based on this, as... Figure 1 As shown, the side enclosure 230 is also provided with a second ventilation opening 220 that connects the internal space and the external space and is used to avoid electronic components 310.

[0049] Since the first vent 210 has already provided a heat dissipation channel for the interior of the sealed bracket 200, the electronic components 310 located inside the internal space require additional heat dissipation channels due to their higher heat dissipation requirements. The second vent 220 is designed to supplement the heat dissipation requirements of the electronic components 310, ensuring that all electronic components 310 can receive sufficient heat dissipation.

[0050] Furthermore, by setting a second vent 220 at a position corresponding to the electronic component 310, air can be guided more effectively to flow more directly through the high-heat electronic component 310, thereby improving heat dissipation efficiency. This helps to reduce the heat island effect, ensures a relatively uniform temperature distribution inside the sealed bracket 200, and helps to improve the reliability and service life of the circuit board 300 and its electronic components 310, reduce the failure rate, and thus enhance the user experience.

[0051] Furthermore, in this embodiment, the height of the second vent 220 is less than the length of the second vent 220, that is, the outline shape of the second vent 220 in the vertical direction is elongated.

[0052] Although the second vent 220 is relatively short in height, it is relatively long in length. This helps to ensure the surface area of ​​the second vent 220 in contact with the outside air, thereby ensuring the heat dissipation effect of the electronic component 310. Moreover, because the second vent 220 is relatively short in height, insects cannot pass through directly, forming a natural physical barrier. This reduces the possibility of insects entering the sealed bracket 200 and damaging the electronic component 310. It also prevents debris from entering the air conditioner control system and causing short circuits or overheating that could lead to system failure.

[0053] Specifically, the vertical dimension (Y-direction) of the second vent 220 is its height, which is 0.9mm to 1.2mm. For example, the length of the second vent 220 is 1mm. The horizontal dimension (X-direction) of the second vent 220 is its length, which is greater than or equal to 10mm, and is at least 1.5 times the length of the electronic component 310.

[0054] The second vent 220, designed with the above dimensions, not only properly meets the external heat dissipation requirements of the electronic component 310, but also effectively performs insect prevention function while ensuring sufficient heat dissipation area by reducing the height of the second vent 220 and extending its length. Thus, it achieves a good balance between fully meeting the external heat dissipation requirements of the electronic component 310 and significantly improving the protective performance of the sealing bracket 200.

[0055] like Figure 1 As shown, the sealing bracket 200 is provided with a reinforcing support column 250, with the two ends of the reinforcing support column 250 connected to the heat sink 100 and the circuit board 300, respectively. By providing the reinforcing support column 250 on the sealing bracket 200, the overall mechanical strength of the sealing bracket 200 can be increased, preventing deformation or damage to the sealing bracket 200 due to vibration, impact, or long-term load. This helps ensure the stability of the connection between the heat sink 100 and the circuit board 300. Moreover, the reinforcing support column 250 can enhance the structural integrity and stability of the sealing bracket 200, helping to extend the service life of the sealing bracket 200 and reduce material fatigue and aging problems caused by environmental factors (such as temperature fluctuations and humidity changes).

[0056] During installation, a first mounting hole can be provided at the top of the reinforcing support 250, and a second mounting hole corresponding to the first mounting hole can be provided on the radiator 100. Similarly, a third mounting hole can be provided at the bottom of the reinforcing support 250, and a fourth mounting hole corresponding to the third mounting hole can be provided on the circuit board 300. The above assembly method ensures that the radiator 100 and the circuit board 300 can be precisely aligned after assembly. This is crucial for maintaining good electrical connection and heat dissipation contact, and helps maintain the overall performance and reliability of the electronic control device.

[0057] Furthermore, the cross-sectional dimension of the reinforcing strut 250 is greater than the thickness of the side circumference 230, meaning that at least the length of the cross-section of the reinforcing strut 250 is greater than the thickness of the side circumference 230. The larger cross-sectional dimension means that the reinforcing strut 250 has a larger cross-sectional area, thus providing stronger bending and shear resistance, which helps resist external loads and vibrations, ensuring the stability and safety of the sealed support 200 and its internal components.

[0058] In one embodiment, please refer to Figure 2 and Figure 3 The reinforcing strut 250 and the sealing bracket 200 are integrally molded. The integral molding design means that there are no seams or connection points between the reinforcing strut 250 and the sealing bracket 200, thereby reducing structural weaknesses caused by poor connections. This design makes the entire structure more robust and stable, better able to resist external loads and vibrations, and ensures the integrity and reliability of the sealing bracket 200.

[0059] In other embodiments, the reinforcing strut 250 can be connected to the sealing bracket 200 by welding or detachment. In particular, the reinforcing strut 250 can be made of a material that is stronger than the sealing bracket 200 to suit different application scenarios.

[0060] like Figure 2 As shown, the cross-section of the reinforcing pillar 250 can be circular, that is, the reinforcing pillar 250 is cylindrical. The diameter of the reinforcing pillar 250 is greater than the thickness of the side circumference 230. The two ends of the reinforcing pillar 250 are respectively connected to the heat sink 100 and the circuit board 300.

[0061] The reinforcing support column 250 structure in the above embodiments is merely exemplary, and the structure of the reinforcing support column 250 is not limited thereto. Those skilled in the art can adjust the external structure of the reinforcing support column 250 as needed, as long as it has the above functions.

[0062] It should be noted that you should refer to [link / reference]. Figures 1 to 3When multiple reinforcing supports 250 and multiple first vents 210 are simultaneously configured on the sealing bracket 200, the design layout becomes particularly critical. Specifically, one or more first vents 210 are distributed between two adjacent reinforcing supports 250. These first vents 210 can be distributed vertically or horizontally to ensure good airflow. To further enhance structural stability, reinforcement members 240 can be provided not only between two adjacent first vents 210, but also in the adjacent areas between the reinforcing supports 250 and the first vents 210. This not only improves the overall structural strength of the sealing bracket 200, but also ensures its reliability and durability in complex environments.

[0063] This utility model also provides an air conditioner, which includes the electronic control device in any of the foregoing technical solutions.

[0064] This invention provides a small first ventilation opening 210 on the sealing bracket 200 as a heat dissipation opening. This not only ensures the heat dissipation effect of the sealing bracket 200 to the outside, but also prevents insects or debris from entering the air conditioner control system and causing short circuits or overheating that could lead to system failure. This balances the requirements of heat dissipation effect and protection performance of the radiator 100 bracket, achieving an effective balance between the two.

[0065] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
