Description

Technical Field

[0001] This application belongs to the field of air conditioning technology, and in particular relates to an electrical control box and an air conditioner. Background Technology

[0002] Currently, the main control board of an air conditioner is generally installed directly exposed to the environment. In most cases, this installation method does not pose a safety hazard. However, in air conditioning units that use refrigerants with "flammable and explosive" properties, the components on the main control board may spark, and the air conditioning unit may leak refrigerant. When these two situations occur simultaneously, there is a safety hazard of combustion and explosion.

[0003] To address this safety hazard, a solution has emerged that uses a sealed box and potting process to completely seal the main control board. While this method of completely sealing the main control board with potting can effectively reduce the safety hazard, it also significantly impacts the heat dissipation performance of the main control board and increases the difficulty of wiring and after-sales maintenance. Utility Model Content

The bracket includes a heat dissipation part and a mounting part with a mounting opening. The main control board is disposed on the mounting part, and the heat dissipation part is disposed on the side of the mounting part away from the main control board and forms a heat dissipation channel with the mounting part. The heat sink is embedded in the mounting opening and partially located within the heat dissipation channel, and the side of the heat sink facing the main control board is in contact with the main control board. The box body and the box cover are detachably connected and form a sealed space. The box body has a clearance opening, and the mounting part closes the clearance opening.

The lower end of the third side plate is detachably connected to the upper end of the first side plate, and the lower end of the fourth side plate is detachably connected to the upper end of the second side plate. The side of the third side plate away from the fourth side plate is detachably connected to the first connecting plate, and the side of the fourth side plate away from the third side plate is detachably connected to the second connecting plate.

[0010] Optionally, the lower end of the third side plate is provided with a positioning member, and the positioning member and the third side plate form a positioning groove with the slot facing downward, and the upper end of the second side plate is inserted into the positioning groove.

[0011] Optionally, a sealing element is provided at the contact point between the base and the partition, a sealing element is provided at the contact point between the base and the box lid, and a sealing element is provided at the contact point between the partition and the box lid.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0039] This application provides an electronic control box 100, such as... Figures 1 to 15 As shown, the electrical control box 100 includes a box body 110, a box cover 120, a heat sink 130, a main control board 140, and a bracket 150. The bracket 150 includes a heat dissipation part 151 and a mounting part 152 with a mounting opening. The main control board 140 is disposed on the mounting part 152. The heat dissipation part 151 is disposed on the side of the mounting part 152 away from the main control board 140 and forms a heat dissipation channel 153 with the mounting part 152. The heat sink 130 is embedded in the mounting opening and partially located within the heat dissipation channel 153. The side of the heat sink 130 facing the main control board 140 is in contact with the main control board 140. The box body 110 and the box cover 120 are detachably connected and form a sealed space 101 (e.g., Figure 2(The dotted area in the text) The box body 110 is provided with a clearance opening 102, the mounting part 152 closes the clearance opening 102, the main control board 140 is located inside the sealed space 101, and the heat dissipation channel 153 is located outside the sealed space 101; the box cover 120 forms an air intake channel 103 isolated from the sealed space 101, and the two ends of the heat dissipation channel 153 are respectively provided with an air inlet 154 and an air outlet 155, and the air inlet 154 is connected to the air intake channel 103.

[0040] The electrical control box 100 and air conditioner provided in this application embodiment are formed by detachably connecting the box body 110 and the box cover 120 to form a sealed space 101. The box cover 120 has an air intake channel 103 isolated from the sealed space 101. The air intake channel 103 is connected to the heat dissipation channel 153. The radiator 130 is partially located in the heat dissipation channel 153. The mounting part 152 of the bracket 150 closes the clearance opening 102 on the box body 110. The main control board 140 and the heat dissipation channel 153 are located inside the sealed space 101 and the sealed space 101, respectively. Externally, this isolates the air in the air intake channel 103 and the heat dissipation channel 153 from the main control board 140, reducing the risk of combustion and explosion when both sparks from electronic components 141 on the main control board 140 and refrigerant leakage occur simultaneously, thus improving safety. Moreover, since the box body 110 and the box cover 120 are detachably connected, when engineering wiring or maintenance is required, only the box cover 120 needs to be removed for operation, which improves the convenience of engineering wiring and maintenance operations and reduces the difficulty of engineering wiring and after-sales maintenance.

[0041] It is understood that by placing the heat dissipation channel 153 outside the enclosed space 101 and the main control board 140 inside the enclosed space 101, this application ensures that the electronic components 141 on the main control board 140 operate in an independent, enclosed environment. This eliminates the risk of leaked flammable refrigerant coming into contact with the electronic components 141 and causing an explosion, thus ensuring the safety of air conditioners using flammable refrigerant and reducing the safety hazards associated with using flammable refrigerant. Simultaneously, since the side of the radiator 130 facing the main control board 140 is in contact with it, the heat generated on the main control board 140 can be transferred to the radiator 130 through thermal conduction, thereby achieving heat dissipation from the radiator 130 to the main control board 140. Figure 2 As shown ( Figure 2 (The thick black arrow in the image indicates the direction of airflow). When air enters the heat dissipation channel 153 from the air inlet channel 103, the air will flow through the radiator 130 and then out from the air outlet 155, thereby carrying away the heat on the radiator 130 and achieving the heat dissipation effect.

[0042] In some embodiments of this application, combined with Figure 6 , Figure 7 , Figure 10 , Figure 11 and Figure 15 As shown, the mounting part 152 has a hook 156 on the side opposite to the main control board 140, and the housing 110 has a hanging hole 104, with the hook 156 engaging with the hanging hole 104. This arrangement allows the bracket 150 to be detachably connected to the housing 110. It is understood that, to improve the stability of the connection between the mounting part 152 and the housing 110, the mounting part 152 and the housing 110 can also be connected by screws.

[0043] Optionally, there can be multiple hanging holes 104. At least one hanging hole 104 can be provided on each of the left and right sides of the clearance opening 102, and at least one hanging hole 104 can also be provided on the lower side of the clearance opening 102. The number of hooks 156 is the same as the number of hanging holes 104, and multiple hooks 156 are hooked one-to-one with multiple hanging holes 104.

[0044] For example, such as Figure 7 and Figure 11 As shown, there are six hanging holes 104. Two hanging holes 104 are provided on each of the left and right sides of the clearance opening 102, and two hanging holes 104 are also provided on the lower side of the clearance opening 102; as shown... Figure 7 and Figure 15 As shown, the mounting part 152 has six hooks 156 on the side opposite to the main control board 140, and the six hooks 156 are hooked one-to-one with the six hanging holes 104.

[0045] In some embodiments of this application, such as Figures 1 to 7 As shown, the box body 110 includes a base 111 and a partition 112. Figure 10 and Figure 11 As shown, a first connecting plate 1121 and a second connecting plate 1122 are provided on both opposite sides of the partition 112, and a clearance opening 102 and a hanging hole 104 are provided on the partition 112; Figure 8 and Figure 9 As shown, the base 111 includes a base plate 1111, a first side plate 1112, and a second side plate 1113. The base plate 1111 is detachably connected to the lower end of the partition plate 112. The first side plate 1112 is connected to the second side plate 1113, and the lower ends of both are detachably connected to the base plate 1111. The side of the first side plate 1112 away from the second side plate 1113 is detachably connected to the first connecting plate 1121, and the side of the second side plate 1113 away from the first side plate 1112 is detachably connected to the second connecting plate 1122. This facilitates the installation of the bracket 150 onto the housing 110, so that the mounting portion 152 closes the clearance opening 102.

[0046] Optional, such as Figure 2 and Figure 8As shown, the lower end of the second side plate 1113 is inclined toward the side closer to the partition 112. It can be understood that since the electronic components 141 at the lower end of the main control board 140 are relatively small, the lower end of the second side plate 1113 is inclined toward the side closer to the partition 112, thereby reducing the space occupied by the electronic control box 100 and achieving the effect of saving space.

[0047] Optionally, the second side plate 1113 is provided with a waterproof cable connector 113 for wiring. The waterproof cable connector 113 isolates the wiring point from the outside air, which can effectively prevent leaked flammable refrigerant gas from coming into contact with the wiring point, further improving safety.

[0048] In some embodiments of this application, such as Figure 12 and Figure 13 As shown, the lid 120 includes a top plate 121, a third side plate 122, and a fourth side plate 123. The top plate 121 is detachably connected to the upper end of the partition 112. The third side plate 122 and the fourth side plate 123 are detachably connected, and the upper ends of both are detachably connected to the top plate 121. The lower end of the third side plate 122 is detachably connected to the upper end of the first side plate 1112, and the lower end of the fourth side plate 123 is detachably connected to the upper end of the second side plate 1113. The side of the third side plate 122 away from the fourth side plate 123 is detachably connected to the first connecting plate 1121, and the side of the fourth side plate 123 away from the third side plate 122 is detachably connected to the second connecting plate 1122. This configuration allows the lid 120 to be detachably mounted on the box body 110.

[0049] Optional, such as Figures 1-5 and Figure 12 As shown, the lower end of the third side plate 122 is provided with a positioning member 124, and the positioning member 124 and the third side plate 122 form a positioning groove 125 with the groove facing downward (e.g. Figure 3 As shown, the upper end of the second side plate 1113 is inserted into the positioning groove 125. This arrangement allows the third side plate 122 to be quickly positioned on the second side plate 1113 during the assembly of the cover 120 and the base 111, improving assembly efficiency.

[0050] In some embodiments of this application, the box body 110 and the box cover 120 can be detachably connected by screws. Specifically, the bottom plate 1111 and the lower end of the partition plate 112 are connected by screws, the first side plate 1112 and the second side plate 1113 are connected by screws, and the lower ends of both the first side plate 1112 and the second side plate 1113 are connected to the bottom plate 1111 by screws; the side of the first side plate 1112 away from the second side plate 1113 is connected to the first connecting plate 1121 by screws, and the side of the second side plate 1113 away from the first side plate 1112 is connected to the second connecting plate 1122 by screws; the third side plate 122 of the box cover 120 is connected to the first connecting plate 1121 by screws. The four side plates 123 are connected by screws, and the upper ends of the third side plate 122 and the fourth side plate 123 are both connected to the top plate 121 by screws; the lower end of the third side plate 122 is connected to the upper end of the first side plate 1112 by screws, and the lower end of the fourth side plate 123 is connected to the upper end of the second side plate 1113 by screws; the side of the third side plate 122 away from the fourth side plate 123 is connected to the first connecting plate 1121 by screws, and the side of the fourth side plate 123 away from the third side plate 122 is connected to the second connecting plate 1122 by screws.

[0051] In some embodiments of this application, a sealing element is provided at the contact point between the base 111 and the partition 112, at the contact point between the base 111 and the lid 120, and at the contact point between the partition 112 and the lid 120. By attaching sealing elements to the contact points of the base 111, the partition 112, and the lid 120, the sealing effect of the enclosed space 101 can be improved. Optionally, the sealing element is a sponge, a rubber gasket, or a silicone gasket.

[0052] In some embodiments of this application, such as Figure 2 , Figure 6 and Figure 15 As shown, a baffle plate 160 is provided on the mounting part 152. The baffle plate 160 is arranged opposite to the air outlet 155 and there is a gap between them. By providing the baffle plate 160, water can be prevented from splashing into the heat dissipation channel 153 when the outdoor fan 200 of the air conditioner rotates.

[0053] This application also provides an air conditioner, such as... Figures 16-17 As shown, the air conditioner includes an electrical control box 100, the specific structure of which is described in the above embodiments. Since this air conditioner employs all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.

[0054] Optionally, the air conditioner can be a single-unit air conditioner (such as a window air conditioner) or a split-type air conditioner. When the air conditioner is a single-unit air conditioner, the interior of the casing is divided into an indoor side and an outdoor side, and the electrical control box 100 is located on the outdoor side. When the air conditioner is a split-type air conditioner, it includes an indoor unit and an outdoor unit, and the electrical control box 100 is located inside the casing of the outdoor unit.

[0055] For example, when the air conditioner is a split-type air conditioner, such as Figure 16 and Figure 17 As shown, the outdoor unit of the air conditioner includes components such as a casing, an outdoor fan 200, an outdoor heat exchanger 300, and a compressor. The internal space of the casing is divided into a fan chamber and a compressor chamber by a partition 400. The outdoor fan 200 and the outdoor heat exchanger 300 are both located in the fan chamber, and the compressor is located in the compressor chamber. The electrical control box 100 is located at the upper end of the partition 400, and the heat dissipation channel 153 is located in the fan chamber. The air inlet channel 103 is connected to the compressor chamber. When the outdoor fan 200 starts, a pressure difference is generated between the air inlet 154 and the air outlet 155 of the heat dissipation channel 153. This draws air from the compressor chamber side into the heat dissipation channel 153 through the air inlet channel 103, flows through the radiator 130, and finally flows out from the air outlet 155. The air flowing out from the air outlet 155 merges with the air in the fan chamber and is blown towards the outside of the air conditioner casing, achieving a heat dissipation effect.

[0056] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0057] The electrical control box and air conditioner provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
