Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more particularly to a main control board, controller, outdoor unit, and air conditioner for an air conditioning system. Background Technology

[0002] In related technologies, the power devices of the controller used for air conditioner outdoor units are arranged in several ways: The first is that all power devices are arranged in a straight line, with the bus capacitor located on one side of the power devices, either outside or inside. However, in this arrangement, the controller length limit may not meet the space requirements for a straight-line arrangement of all power devices, and the power supply cable for the outermost fan IPM module is too long. The second arrangement is that the fan IPM module is located in a corner of the controller, arranged at right angles to the other power devices, with the bus capacitor located outside the other power devices. However, in this arrangement, if the fan IPM module and compressor IPM module use a topology with all-high-voltage power supply, the power supply cable for the fan IPM module is also too long.

[0003] In both of these forms, excessively long traces can lead to electromagnetic interference (EMI) problems, and safety requirements between traces can also result in traces occupying a large area of ​​the printed circuit board (PCB). Summary of the Invention

[0040] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0041] In the description of this invention, "several" means one or more, "multiple" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the number itself, while "above," "below," "within," etc. are understood to include the number itself. "Any one" refers to one or more, and "at least one of the following" and similar expressions refer to any combination of these items, including any combination of single or multiple items. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0042] It should be noted that the terms "setting," "installing," and "connecting" in the embodiments of this invention should be interpreted broadly. Those skilled in the art can reasonably determine the specific meaning of the above terms in the embodiments of this invention in conjunction with the specific content of the technical solution. For example, the term "connection" can be a mechanical connection, an electrical connection, or a connection that allows for mutual communication; it can be a direct connection or an indirect connection through an intermediate medium.

[0043] It should be noted that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0044] In some cases, the power devices of the controller used for air conditioner outdoor units are arranged in the following ways: The first is that all power devices are arranged in a straight line, with the bus capacitor located on one side of the power devices, either outside or inside. However, in this arrangement, the controller length limit may not meet the space requirements for a straight-line arrangement of all power devices, and the power supply cable for the outermost fan IPM module is too long. The second arrangement is that the fan IPM module is located in a corner of the controller, arranged at right angles to the other power devices, with the bus capacitor located outside the other power devices. However, in this arrangement, if the fan IPM module and compressor IPM module use a topology with all-high-voltage power supply, the power supply cable for the fan IPM module is also too long.

[0045] In both of these forms, excessively long traces can lead to electromagnetic interference (EMI) problems, and safety requirements between traces can also result in traces occupying a large area of ​​the printed circuit board (PCB).

[0046] Based on this, embodiments of the present invention provide a main control board, controller, outdoor unit and air conditioner for an air conditioning system, which improves the rationality of wiring between modules and thus improves the EMI problem between modules.

[0047] The various embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0048] Reference Figure 1-2 , Figure 1 This is a circuit diagram of the main control board of an air conditioning system provided in one embodiment of the present invention. Figure 2 This is a schematic diagram of the main control board of an air conditioning system provided in an embodiment of the present invention. The main control board of the air conditioning system includes a bus capacitor module 110, a compressor IPM module 120, and a fan IPM module 130. The main control board is divided into a first region 100, a second region 200, and a third region 300 along a first direction. Among them, the compressor IPM module 120 is arranged in the first region 100; the bus capacitor module 110 is arranged in the second region 200; and the fan IPM module 130 is arranged in the third region 300. The compressor IPM module 120 and the fan IPM module 130 are respectively connected to the bus capacitor module 110 through a power bus laid on the main control board.

[0049] Reference Figure 1-2 In this embodiment of the invention, a main control board for an air conditioning system is provided, which further includes a rectifier module / PFC module 140.

[0050] In the main control board of the air conditioning system provided in this embodiment of the invention, the compressor IPM module 120 and the fan IPM module 130 are respectively connected to the bus capacitor module 110 via the power bus laid on the main control board. The compressor IPM module 120 is on one side, the fan IPM module 130 is on the other side, and the bus capacitor module 110 is located between the compressor IPM module 120 and the fan IPM module 130. The fan IPM module 130 can draw power from the corresponding bus capacitor module 110 nearby, which can shorten the length of the wiring between the compressor IPM module 120 and the bus capacitor module 110, as well as the length of the wiring between the fan IPM module 130 and the bus capacitor module 110. This can improve the rationality of the wiring between the modules, thereby improving the EMI problem between the modules. In this embodiment of the invention, the bus capacitor module 110, compressor IPM module 120, and fan IPM module 130 of the air conditioning system are arranged by placing the bus capacitor module 110 in the middle position between the compressor IPM module 120 and the fan IPM module 130. The fan IPM module 130 can draw power from the corresponding bus capacitor module 110 nearby. At the same time, the wires of the fan IPM module 1230 and the bus capacitor module 110 do not cross, which can improve the rationality of the wiring between the modules and thus improve the EMI problem between the modules.

[0051] Reference Figures 3 to 7 , Figure 3 This is a circuit diagram of the main control board of an air conditioning system provided in another embodiment of the present invention; Figure 4 This is a schematic diagram of the main control board of an air conditioning system provided in another embodiment of the present invention; Figure 5 This is a schematic diagram of the main control board of an air conditioning system provided in another embodiment of the present invention; Figure 6 This is a schematic diagram of the main control board of an air conditioning system provided in one embodiment of the present invention; Figure 7 This is a schematic diagram of the main control board of an air conditioning system provided in one embodiment of the present invention.

[0052] In the main control board of the air conditioning system provided in this embodiment of the invention, the bus capacitor module 110 includes a first bus capacitor sub-module 111 and a second bus capacitor sub-module 112 that are connected to each other; the fan IPM module 130 includes a first fan IPM sub-module 131 and a second fan IPM sub-module 132 that are connected to each other; wherein, the first fan IPM sub-module 131 is connected to the first bus capacitor sub-module 111, and the second fan IPM sub-module 132 is connected to the second bus capacitor module 112.

[0053] In this embodiment, the first bus capacitor submodule 111 and the second bus capacitor submodule 112 are interconnected, and the first fan IPM submodule 131 and the second fan IPM submodule 132 are interconnected. The first fan IPM submodule 131 is connected to the nearest first bus capacitor submodule 111. This connection method can shorten the length of the wiring between the first fan IPM submodule 131 and the first bus capacitor submodule 111. Similarly, the second fan IPM submodule 132 is connected to the nearest second bus capacitor submodule 112. This connection method can shorten the length of the wiring between the second fan IPM submodule 132 and the second bus capacitor submodule 112.

The first bus capacitor submodule 111 and the first fan IPM submodule 131 are respectively connected to the first bus, and the second bus capacitor submodule 112 and the second fan IPM submodule 132 are respectively connected to the second bus. The connection between the first bus capacitor submodule 111 and the second bus capacitor submodule 112, and the connection between the first fan IPM submodule 131 and the second fan IPM submodule 132, are connected by copper foil arranged on the main control board.

[0055] Reference Figures 4 to 7 In this embodiment, the first busbar is located on the first side, and the second busbar is located on the second side. The first busbar capacitor submodule 111 and the first fan IPM submodule 131 are both connected to the nearest first busbar, so that the first fan IPM submodule 131 can draw power from the corresponding first busbar nearby. Similarly, the second busbar capacitor submodule 112 and the second fan IPM submodule 132 are both connected to the nearest second busbar, so that the second fan IPM submodule 132 can draw power from the corresponding second busbar nearby. This connection method eliminates the need for the wiring between the busbar capacitor module 110 and the fan IPM module 130 to cross, thereby improving the rationality of the wiring between the modules.

[0056] Understandably, the connections between the bus capacitor submodules and between the fan IPM submodule 130 are made of copper foil, which helps dissipate the heat generated during circuit operation.

[0057] Reference Figures 4 to 7In the main control board of the air conditioning system provided in the embodiment of the present invention, the first bus capacitor submodule 111 and the second bus capacitor submodule 112 are arranged along the second direction in the second region 200, and the second direction is the same as or different from the first direction; the first fan IPM submodule 131 and the second fan IPM submodule 132 are arranged along the third direction in the third region 300, and the third direction is the same as or different from the first direction, and the third direction is the same as or different from the second direction.

[0058] In this embodiment, the bus capacitor submodule and the fan IPM submodule can be arranged in different directions in the second region 200 and the third region 300, which increases the design flexibility. The arrangement direction of the first bus capacitor submodule 111 and the second bus capacitor submodule 112 can be the same as or different from the first direction, which helps to optimize space utilization and heat dissipation performance.
