[0045] The utility model provides an electric control component.

[0046] See also Figures 1 to 4 In one embodiment of the present utility model, the electric control component includes:

[0047] The circuit board 100 comprises a first area 101 and a second area 102 distributed along the board surface, wherein the control module and the power device on the circuit board 100 are distributed in the first area 101; and

[0048] The first heat dissipation module 200 disposed corresponding to the first area 101 and the second heat dissipation module 300 disposed corresponding to the second area 102 , the heat exchange efficiency of the first heat dissipation module 200 is higher than the heat exchange efficiency of the second heat dissipation module 300 .

[0049] In the technical solution of the present utility model, the control modules and power devices with large heat generation are concentrated in the first area 101 of the circuit board 100. For this area, a first heat dissipation module 200 with higher heat exchange efficiency is used to dissipate heat for the control modules and power devices, so as to meet the requirements of the control modules and power devices for heat dissipation efficiency, which is conducive to reducing the requirements of the air conditioner for the ambient temperature, thereby facilitating the improvement of the operating capacity of the air conditioner; the heat generation of the devices distributed in the second area 102 will be lower than that of the control modules and power devices in the first area 101, and a second heat exchange module with lower heat exchange efficiency is used to dissipate heat for the devices in the second area 102, and the heat exchange efficiency of the second heat exchange module only needs to meet the heat dissipation requirements of these devices, so that the heat dissipation capacity of the heat dissipation module will not be wasted. Therefore, in the technical solution of the present utility model, the devices on the circuit board 100 can be planned by region based on the heat generation, and heat dissipation modules with different heat exchange efficiencies are respectively set for different areas of the circuit board 100, so as to optimize the electronic control heat dissipation of the air conditioner, and ensure the operating performance of the air conditioner without wasting the heat dissipation capacity of the heat dissipation module.

[0050] In one embodiment, the electric control component is configured on the outdoor unit, and the control module includes a main control circuit, a fan control module and a compressor control module.

[0051] The main control circuit is the brain of the air conditioning control system, responsible for receiving the instructions input by the user through the remote control or panel, and coordinating the work of various components according to these instructions. It usually contains a microprocessor or a single-chip microcomputer for processing control logic, and related interface circuits for communicating with external sensors (such as temperature sensors), actuators (such as compressor and fan drive circuits) and other control modules. In addition, it also includes monitoring system status, such as detecting faults, managing safety protection measures (such as overheating protection, current overload protection), and realizing the switching of various operating modes (such as cooling, heating, dehumidification, automatic).

[0052] The compressor control module is responsible for the start-up, operation and speed control of the compressor. It receives instructions from the main control circuit and uses IPM (intelligent power module) or other drive circuits to adjust the power frequency and voltage of the compressor to achieve the required output. In addition, the compressor control module may include a feedback circuit to monitor the actual operating status of the compressor (such as speed, current) to ensure its stable and safe operation.

[0053] The fan control module is responsible for controlling the fan of the outdoor unit and adjusting the speed and direction of air flow. According to the instructions of the main control circuit, the fan control module can change the power supply frequency of the fan, thereby adjusting the fan speed and realizing stepless or multi-speed adjustment of the air volume. In addition, the fan control module also includes necessary protection mechanisms to prevent the fan from overloading or abnormal operation.

[0054] In one embodiment, the circuit board 100 is further provided with passive devices, EMC (Electromagnetic Compatibility) circuits and relays, and the passive devices, the EMC circuits and the relays are arranged in the second area 102. Specifically, the power devices include one or more of an intelligent power module, an IGBT, a rectifier bridge, and a fast recovery diode, and the passive devices include one or more of a common mode inductor, a PFC inductor, an electrolytic capacitor, an X capacitor and a PTC thermistor. In this way, different types of devices on the circuit board 100 can cooperate and work together to achieve multiple functions of the air conditioner.

[0055] In one embodiment, the first heat dissipation module 200 is configured as a liquid cooling module, and the second heat dissipation module 300 is configured as an air cooling module. It can be understood that the liquid cooling module has a higher cooling efficiency. Compared with air, liquid can absorb and transfer heat more effectively, reduce temperature fluctuations and hot spots, and liquid can distribute heat more evenly to ensure the temperature consistency of each part inside the system, so that the first heat dissipation module 200 can effectively dissipate heat for the devices in the first area 101; and the air cooling module has fewer components, and is relatively easy to install and maintain, so that the second heat dissipation module 300 can conveniently and effectively dissipate heat for the second area 102. In this way, the heat exchange efficiency of the first scattering module can be higher than the heat exchange efficiency of the second heat dissipation module 300, so that the first heat dissipation module 200 and the second heat dissipation module 300 can respectively meet the heat dissipation requirements of the devices in the first area 101 and the second area 102. Of course, in other embodiments, it is also possible that the first heat dissipation module 200 and the second scattering module are configured as heat dissipation modules with different heat exchange efficiencies and the same heat exchange method.

[0056] In one embodiment, the first heat dissipation module 200 is a refrigerant heat dissipation module. That is, the coolant of the first heat dissipation module 200 is a refrigerant, and the heat exchange efficiency of the refrigerant is high. Compared with the water cooling method, the refrigerant will not produce scale, which is conducive to ensuring the heat dissipation stability of the first heat dissipation module 200. Without loss of generality, the refrigerant flow path of the first heat dissipation module 200 is connected to the compressor, and the compressor is used to complete the circulation of the refrigerant in the first heat dissipation module 200 to ensure the heat dissipation effect of the first heat dissipation module 200. Of course, in other embodiments, the first heat dissipation module 200 can also use water or other media as the coolant.

[0057] In one embodiment, if Figure 3 and Figures 5 to 9 As shown, the first heat dissipation module 200 includes a heat exchange plate 210, and the heat exchange plate 210 is formed with a refrigerant flow channel, and the refrigerant flow channel is connected to the compressor of the air conditioner. In this way, the refrigerant in the refrigerant flow channel can directly exchange heat with the heat exchange plate 210 without passing through other components such as pipes, which is conducive to reducing heat loss, thereby ensuring that the first heat dissipation module 200 has sufficient heat dissipation efficiency. Among them, the heat exchange plate 210 can be processed and formed in an integrated molding manner to ensure the production efficiency of the first heat dissipation module 200. Specifically, the internal structure of the heat exchange plate 210 directly forms a refrigerant flow channel, and the two ends of the refrigerant flow channel penetrate the outer surface of the heat exchange plate 210 as the inlet and outlet of the refrigerant flow channel. The refrigerant flow channel is connected to the pipeline on the compressor via the inlet and outlet, thereby forming a closed cooling circuit. Of course, in other embodiments, the first heat dissipation module 200 can also be that the refrigerant pipe directly extends to the position corresponding to the first area 101 to form a corresponding cooling circuit, and a plate can also be set outside the refrigerant pipe to improve the heat exchange efficiency.

[0058] In one embodiment, please refer to Figure 6 , the heat exchange plate 210 is configured to be made of aluminum alloy, and the inlet and outlet of the refrigerant flow channel are both connected to the joint pipe 211 made of aluminum alloy. It can be understood that the thermal conductivity of aluminum alloy is high, and it can quickly absorb and transfer heat, realize efficient heat energy conversion, and dissipate heat quickly and efficiently. In addition, the density of aluminum alloy is small and the weight is light. Under the same heat dissipation capacity, the aluminum alloy product is smaller in volume and lighter in weight, which helps to reduce energy consumption and use cost. In addition, a dense oxide layer is easily formed on the surface of aluminum alloy, which can effectively resist corrosion in the atmosphere and water and prolong the service life. Aluminum alloy is soft and easy to process, and can be easily processed into a heat exchange plate 210 with a refrigerant flow channel formed inside. Moreover, the cost of aluminum alloy is also lower than that of copper.

[0059] Since the material of the pipes on the compressor is copper, it is easy to have poor welding when welding with the plane of the aluminum alloy product. In order to improve the connection stability between the refrigerant flow channel of the heat exchange tube and the compressor. In this embodiment, the joint pipe 211 made of aluminum alloy is used to weld with the heat exchange plate 210. Since the joint pipe 211 and the heat exchange plate 210 are both made of aluminum alloy, they can be stably welded together, and the joint pipe 211 and the copper pipe on the compressor have high structural consistency and can also be well welded together. In this way, the heat exchange plate 210 can be stably connected to the copper pipe on the compressor through the joint pipe 211 to ensure stable heat dissipation of the first heat dissipation module 200. Of course, in other embodiments, the heat exchange plate 210 can also be configured as copper material to facilitate welding of the copper pipe on the compressor to it.

[0060] In one embodiment, please refer to Figure 1 and Figure 2 The electric control component further includes a protective shell 400, the circuit board 100 is mounted on the protective shell 400, one side of the protective shell 400 is open, and the components of the circuit board 100 are exposed on the open side of the protective shell 400, and the first heat dissipation module 200 and the second heat dissipation module 300 are both arranged corresponding to the open side of the protective shell 400. In this way, the circuit board 100 will be located between the heat dissipation module and the protective shell 400, and will not be exposed, which can well protect the circuit board 100, and the first heat dissipation module 200 and the second heat dissipation module 300 are both located on the same side of the circuit board 100, which is conducive to optimizing the layout structure of the electric control component, and can control the structure of the electric control component to be relatively regular, which is convenient for the installation of the electric control component in the whole machine, and the opening set on the protective shell 400 allows the components on the circuit board 100 to be exposed, and the first heat dissipation module 200 and the second heat dissipation module 300 can more directly dissipate heat for the components on the circuit board 100, which is conducive to improving the heat dissipation effect of the heat dissipation module on the components. Of course, in other embodiments, the circuit board 100 may be inserted through the first heat dissipation module 200 and the second heat dissipation module 300, and the heat dissipation modules can dissipate heat for the components on the circuit board 100 on both sides.

[0061] In one embodiment, please refer to Figure 4 and Figure 5, the second heat dissipation module 300 includes an air duct component 310, and the air duct component 310 is provided with a avoidance opening 314 on the side facing the protective shell 400, so that the corresponding device on the circuit board 100 can be inserted, and the protective shell 400 is covered and engaged with the avoidance opening 314. In this way, the circuit board 100 can be stably clamped therein through the cooperation of the protective shell 400 and the air duct component 310, which is conducive to ensuring the installation stability of each structure of the electronic control component. Furthermore, the protective shell 400 and the air duct component 310 can also be indirectly or directly connected through other structures to improve the connection stability of the two. For example, the two can also be connected by screw locking. In addition, the device of the second area 102 on the circuit board 100 extends into the internal air duct of the air duct component 310 through the avoidance opening 314, which can greatly increase the heat exchange area between the device and the air, which is conducive to sufficient heat exchange between the air and the device, thereby improving the heat dissipation effect of the air on the device in the second area 102 to ensure the working performance of the device in the second area 102.

[0062] In one embodiment, please refer to Figures 1 to 3 The outdoor unit includes a middle partition 20, and a compressor cavity 31 and a fan cavity 32 are formed on both sides of the middle partition 20, respectively. The electric control component is arranged corresponding to the compressor cavity 31, and the compressor cavity 31 is formed with an air inlet area 11 connected to the outdoor environment and an air outlet area 503 connected to the fan cavity 32. The second heat dissipation module 300 includes an air duct component 310, and a heat dissipation air duct is formed in the air duct component 310, and the two ports of the heat dissipation air duct are respectively connected to the air inlet area 11 and the air outlet area 503. Therefore, when the fan is running, the air of the outdoor environment will enter the air duct component 310 from the air inlet area 11, and then flow into the fan cavity 32 through the air outlet area 503, and finally flow out through the air outlet mesh cover of the outdoor unit. In this way, the second heat dissipation module 300 can use the fan in the fan cavity 32 to form forced convection heat dissipation for the devices in the second area 102 in the air duct component 310 to ensure the heat dissipation efficiency of the second heat dissipation module 300. Furthermore, the second heat dissipation module 300 can introduce air from the outdoor environment through the air inlet area 11 to exchange heat with the components in the second area 102. Compared with the air in the internal environment of the outdoor unit, the temperature difference between the air in the outdoor environment and the components in the second area 102 is greater, so the heat dissipation effect on the components in the second area 102 is better. Of course, in other embodiments, an additional fan may be provided in the air duct component 310, and the outlet of the air duct component 310 is also directly connected to the outdoor environment.

[0063] In one embodiment, please refer to Figures 1 to 3The electric control assembly further comprises a support box 500, a notch is provided at the upper end of the middle partition 20, the support box 500 is clamped in the notch, a first opening 501 is provided above the support box 500, the protective shell 400 covers the first opening 501, a second opening 502 is provided on the side of the support box 500, and the first heat dissipation module 200 and the second heat dissipation module 300 extend between the protective shell 400 and the support box 500 through the second opening 502. In this way, the support box 500 can provide support for the first heat dissipation module 200, the second heat dissipation module 300, the circuit board 100, the protective shell 400 and other components, and the support box 500 can also provide a connection structure for each component in a targeted manner, so that the components can be installed more conveniently. Specifically, at the notch, the middle partition 20 is provided with a flange, which abuts against the side of the support box body 500. Furthermore, the flange can also be connected to the support box body 500 by welding or screw locking to ensure the connection stability between the support box body 500 and the middle partition 20, thereby ensuring the installation stability of the electric control component. In particular, the support box body 500 also has a portion protruding to the fan cavity 32, so that the electric control component can use part of the space in the fan cavity 32, that is, it can make full use of the space in the outdoor unit to install the electric control component by rationally planning the spatial layout, which is conducive to the miniaturization design of the outdoor unit. At the same time, it can also extend the length of the air duct component 310 to a certain extent, which is conducive to promoting sufficient heat exchange between the air and the devices in the second area 102, so as to ensure the heat dissipation effect of the devices in this area.

[0064] In one embodiment, please refer to Figures 7 to 9 The electric control assembly further includes a first support member 600, which is located between the heat exchange plate 210 and the bottom wall of the support box body 500. In this way, the first support member 600 can support the heat exchange plate 210, so that the heat exchange plate 210 can be close to the circuit board 100 located on the top of the support box body 500, thereby ensuring the heat dissipation effect of the circuit board 100 on the first area 101.

[0065] It can be understood that the air duct component 310 also extends into the support box body 500, and is distributed in the horizontal direction with the heat exchange plate 210. Specifically, the outdoor unit includes a side plate 10 corresponding to the compressor chamber 31, the second opening 502 is opened toward the side plate 10, the air inlet area 11 is provided on the side plate 10, and the air outlet area 503 is provided on the support box body 500 or the middle partition plate 20. The air duct component 310 extends in the left and right direction when the outdoor unit is installed, and the air duct component 310 and the heat exchange plate 210 are distributed in the front and back direction. The support box body 500 provides sufficient space in the height direction of the outdoor unit for the installation of the air duct component 310 to ensure that a sufficient air duct can be formed in the air duct component 310 for sufficient air circulation to exchange heat with the devices in the second area 102, and due to the arrangement of the first support member 600, the heat exchange plate 210 can be lifted to a position close to the first area 101 to ensure the heat exchange effect of the heat exchange plate 210 on the area.

[0066] Further, in this embodiment, please refer to Figure 5 , Figure 8 and Fig. 9 , a plurality of limiting protrusions 610 are spaced apart around the circumference of the first support member 600, and the heat exchange plate 210 is engaged in the space enclosed by the plurality of limiting protrusions 610. In this way, the heat exchange plate 210 can be protected, and the heat exchange plate 210 is not easily displaced, and can be stably arranged relative to the first area 101 to ensure the heat dissipation effect of the heat exchange plate 210 on the first area 101. At the same time, the heat exchange plate 210 is detachably mounted on the first support member 600. When the structure of either of the two is damaged, the corresponding structure can be replaced separately, which is beneficial to saving the maintenance cost of the electronic control components. Of course, in other embodiments, the first support member 600 can also fix the heat exchange plate 210 in other ways, such as screw locking or snap connection.

[0067] Furthermore, in this embodiment, if Fig.10 As shown, the bottom of the first support member 600 is convexly provided with a plurality of mounting buckles 620, and the support box body 500 is correspondingly provided with a plurality of buckle holes 504, and the mounting buckles 620 are buckled in the corresponding buckle holes 504. In this way, the fixed connection between the first support member 600 and the support box body 500 can be achieved, and the connection stability between the two can be guaranteed. At the same time, the first support member 600 is fixed to the support box body 500 in a detachable manner. When the structure of either of the two is damaged, the corresponding structure can be replaced separately, which is conducive to saving the maintenance cost of the electric control component. Of course, in other embodiments, the first support member 600 can also be fixed to the support box body 500 in other ways, such as screw locking or plug-in matching of a convex buckle and a slot.

[0068] Further, in this embodiment, please refer to Figure 8 and Fig. 9 , the electric control assembly further includes a second support member 700, and the second support member 700 is located between the heat exchange plate 210 and the circuit board 100. In this way, the structures of the top and bottom sides of the second support member 700 can be specifically designed so that the two opposite sides of the second support member 700 can be well attached to the circuit board 100 and the heat exchange plate 210, respectively, so as to ensure that the heat exchange plate 210 is located in the first area 101 of the circuit board 100, and the heat exchange plate 210 can also be indirectly attached to the first area 101 of the circuit board 100 through the second support member 700, so that the heat exchange plate 210 and the first area 101 of the circuit board 100 can be better exchanged, which is conducive to ensuring the heat dissipation effect of the first heat dissipation module 200 on the first area 101 of the circuit board 100. Specifically, a plurality of spaced support protrusions 710 are protruded from the top of the second support member 700, and the second support member 700 abuts against the circuit board 100 through the support protrusions 710 to support the circuit board 100. In addition, ribs may also be provided on the periphery of the second support member 700 to support the circuit board 100 together with the support protrusions 710.

[0069] In one embodiment, please refer to Figure 2 , Figure 3 , Figure 8 and Fig. 9 , the electric control component also includes a third support member 800, the two sides of which are respectively connected to the side plate 10 and the support box body 500, and at least partially extend obliquely in the up and down direction. In this way, the support box body 500 can be supported by the third support member 800 and the middle partition plate 20 to ensure the installation stability of the electric control component. Specifically, one side of the third support member 800 is connected to the large handle on the side plate 10, and the other side is connected to the bottom of the support box body 500, wherein, as Fig.10 As shown, the bottom of the support box body 500 is provided with a plug hole 505, and the third support member 800 is correspondingly provided with a plug-in protrusion 810, and the plug-in protrusion 810 of the third support member 800 is inserted into the plug hole 505 from the bottom side of the support box body 500. In addition, the third support member 800 and the support box body 500 are also connected by fasteners. For further information, please refer to Figure 8 A boss structure protruding upward is formed on one side of the third support member 800 close to the support box body 500, and then extends downwardly toward the side plate 10. In this way, the structural strength of the third support member 800 is greater, and the supporting effect on the support box body 500 is stronger, which can further improve the installation stability of the electronic control component.

[0070] In one embodiment, please refer to Figure 3In the first direction, the width of the air inlet area 11 is smaller than the width of the air outlet area 503, and in the second direction, the width of the air inlet area 11 is larger than the width of the air outlet area 503, and the air inlet port and the air outlet port of the heat dissipation duct are respectively adapted to the air inlet area 11 and the air outlet area 503. That is, compared with the air outlet port, the width of the air inlet port in the first direction is smaller and the width in the second direction is larger, so that the air inlet port can be adapted to the air inlet area 11, and the air outlet port can be adapted to the air outlet area 503. It can be understood that the air duct component 310 has a variable diameter section to change the width of the air duct in the first direction and the second direction. In this way, when the airflow flows in the air duct component 310, there will be a process of gathering and diffusion, and the flow of the airflow will be more irregular, which is conducive to promoting sufficient heat exchange between the airflow and the devices in the second area 102.

[0071] Furthermore, in this embodiment, if Figure 4 and Figure 7 As shown, the heat dissipation air duct includes a first air guide section 311 and a second air guide section 312 extending sequentially from the air inlet port. In the direction of the air flow path, the vertical width of the first air guide section 311 gradually decreases, the horizontal width of the first air guide section 311 gradually increases, and the horizontal width of the second air guide section 312 gradually increases, so that the vertical width of the air inlet port is greater than the vertical width of the air outlet port, and the horizontal width of the air outlet port is greater than the horizontal width of the air inlet port. It can be understood that the vertical width is the width in the vertical direction, and the horizontal width is the width in the horizontal direction. In this way, compared with the air outlet area 503, the air inlet area 11 has a larger width in the vertical direction and a smaller width in the horizontal direction. In this embodiment, the air inlet area 11 is located on the side plate 10, and the air outlet area 503 is located on the wall of the supporting box body 500 opposite to the side plate 10. Without loss of generality, the air inlet area 11 and the air outlet area 503 are both formed by a plurality of horizontal grille structures arranged in the vertical direction. In this way, the internal space of the indoor unit can be fully utilized to construct an air duct with a large enough volume, so as to ensure that enough air can enter the air duct component 310 to exchange heat with the components in the second area 102 .

[0072] Furthermore, the circuit board 100 is arranged at the edge of the second area 102 corresponding to the connection between the first air guide section 311 and the second air guide section 312, and the air duct component 310 also includes a third air guide section 313 extending from the second air guide section 312 to the air outlet port, and the third air guide section 313 is a section with uniform width. The main part of the second area 102 is arranged corresponding to the third air guide section 313. In this way, the heat exchange area between the air and the second area 102 can be guaranteed, which is beneficial to further ensure the cooling effect of the second area 102.
