[0051] DETAILED DESCRIPTION

[0052] In the prior art, an electrical control box typically houses the electrical control system for equipment such as an air conditioner outdoor unit. For example, electrical components such as circuit boards, compressor capacitors, outdoor fan capacitors, and wiring terminals are assembled within the box. The box typically includes a housing and various components housed within it. However, the numerous components within the box and the complex assembly methods between components and between the components and the box can lead to low levels of automated assembly and poor production efficiency.

[0053] In view of this, in an embodiment of the present invention, the mounting plate and the heat exchanger are connected by a first fastener and a corresponding connecting hole threaded together, and the mounting plate and the shell are connected by a second fastener and a corresponding connecting hole threaded together. In this way, during actual assembly, the mounting plate and the heat exchanger are placed in the shell, and the heat exchanger is located between the mounting plate and the inner bottom surface of the shell. The mounting plate and the heat exchanger are threadedly connected, and then the mounting plate and the shell are threadedly connected, so that the assembly of the electric control box can be realized. Therefore, the present invention simplifies the assembly method of the electric control box, improves the degree of automated assembly of the electric control box, and thus improves production efficiency to a certain extent.

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

Figure 9 This is a structural diagram of the assembly of the box cover and the box body in the electric control box provided in an embodiment of the present application.

[0056] like Figure 1 and Figure 2 As shown, the electric control box 100 provided in this embodiment may include: a housing 110, a mounting plate 120 and a heat exchanger 130, wherein the mounting plate 120 and the heat exchanger 130 can be connected by a first fastener 121 (see Figure 6 shown) and corresponding connection holes (eg Figure 5 The first connecting hole 1321 and the second connecting hole 122 in the body are threadedly connected.

[0057] Combine Figure 2 and Figure 3 As shown, the mounting plate 120 and the heat exchanger 130 are located in the housing 110, and the heat exchanger 130 is located between the mounting plate 120 and the inner bottom surface of the housing 110. The mounting plate 120 and the housing 110 can be fastened together by a second fastener 125 (see FIG. Figure 7 shown) and corresponding connection holes (eg Figure 6 The third connecting hole 123 and the threaded hole 1141a) are threadedly connected.

[0058] In this embodiment, if Figure 3 As shown, the housing 110 may include a box cover 111 and a box body 112, wherein the box cover 111 is connected to the box body 112. Figure 4 As shown, a accommodating cavity 115 with an opening 115a can be provided in the box body 112, and the box cover 111 covers the opening 115a, the mounting plate 120 is arranged opposite to the box cover 111, the heat exchanger 130 is arranged opposite to the bottom of the box body 112, and the mounting plate 120 is threadedly connected to the bottom of the box body 112.

[0059] In this way, the mounting plate 120 and the heat exchanger 130 are located in the accommodating cavity 115 of the box body 112, the heat exchanger 130 is arranged opposite to the bottom of the box body 112, the mounting plate 120 is threadedly connected to the bottom of the box body 112, the mounting plate 120 is arranged opposite to the box cover 111, the box cover 111 is covered on the opening 115a of the box body 112 and is connected to the box body 112, and the overall assembly of the electric control box 100 can be realized.

[0060] The electric control box 100 of the embodiment of the present application can be, for example, a sealed electric control box, which can prevent water droplets, dust and other foreign matter from entering the electric control box and damaging the electronic components inside the electric control box, thereby achieving waterproof, dustproof and corrosion-resistant effects.

[0061] The heat exchanger 130 in the present application can be a microchannel heat exchanger. The microchannel heat exchanger includes at least two groups of microchannels. The at least two groups of microchannels include a plurality of first microchannels for a first refrigerant flow and a plurality of second microchannels for a second refrigerant flow. The second refrigerant flow absorbs heat from the first refrigerant flow to supercool the first refrigerant flow, or the first refrigerant flow absorbs heat from the second refrigerant flow to supercool the second refrigerant flow.

[0062] The microchannel heat exchanger of the present embodiment can also serve as an economizer for an air conditioner. This allows the microchannel heat exchanger to cool the electronic components within the electrical control box while also serving as an economizer. This eliminates the need for an economizer outside the electrical control box, streamlines the air conditioner's structure, saves space, and reduces costs.

[0063] In this embodiment, if Figure 4 As shown, a threaded column 1141 may be provided at the bottom of the box body 112, and a threaded hole 1141a coaxial with the threaded column 1141 may be provided on the threaded column 1141, and a third connecting hole 123 may be provided on the mounting plate 120, and the third connecting hole 123 may be provided corresponding to the threaded hole 1141a, and the mounting plate 120 and the box body 112 may be threadedly connected by threaded cooperation with the third connecting hole 123 and the threaded hole 1141a through a second fastener 125.

[0064] The threaded hole 1141a on the threaded column 1141 located at the bottom of the box body 112 corresponds to the third connecting hole 123 on the mounting plate 120. The threaded hole 1141a and the third connecting hole 123 can be threadedly matched through the second fastener 125, thereby realizing a threaded matching connection between the bottom of the box body 112 and the mounting plate 120, which helps to improve the assembly efficiency between the mounting plate 120 and the bottom of the box body 112.

[0065] In this embodiment, the number of threaded studs 1141 and the number of third connection holes 123 can be multiple, and the multiple threaded studs 1141 can be spaced apart on the bottom of the box body 112 along the length direction of the electric control box 100. By providing multiple threaded studs 1141 on the bottom of the box body 112 and multiple third connection holes 123 on the mounting plate 120, and by spaced apart on the bottom of the box body 112 along the length direction of the electric control box 100, the reliability of the connection between the mounting plate 120 and the bottom of the box body 112 can be improved in this embodiment, thereby preventing failure of the connection between the mounting plate 120 and the bottom of the box body 112.

[0066] In addition, the heat exchanger 130 may also have an escape space (not shown) for the threaded column 1141 to pass through. Providing the escape space on the heat exchanger 130 for the threaded column 1141 to pass through ensures that the threaded column 1141 at the bottom of the box body 112 passes through the escape space on the heat exchanger 130 and is threadedly connected to the mounting plate 120. This ensures a reliable connection between the mounting plate 120 and the bottom of the box body 112 in this embodiment.

[0067] It is understood that, in this embodiment, a mounting seat 1143 may be provided between the threaded column 1141 and the bottom of the box body 112 (see FIG. Figure 4 Specifically, mounting seat 1143 is disposed on the inner bottom wall of housing 112, and threaded post 1141 is disposed on a side of mounting seat 1143 facing away from mounting seat 1143. Furthermore, as an optional embodiment, a gap may be formed between the side of the inner bottom wall of housing 112 facing mounting seat 1143 and the inner bottom wall of housing 112. This gap prevents direct contact between heat exchanger 130 and the inner bottom wall of housing 112 when threaded post 1141 passes through heat exchanger 130 and engages with mounting plate 120, thereby preventing unnecessary heat transfer between the heat exchanger 130 and housing 112.

[0068] See also Figure 4 As shown, in this embodiment, the box body 112 may include a box body and a packaging plate 113. Specifically, the box body may include a bottom plate 114 and a side plate. The side plate may be arranged around a portion of the outer peripheral edge of the bottom plate 114 so that the side of the box body can have a side opening 115a. In addition, the packaging plate 113 may be arranged at the side opening 115a, and the packaging plate 113 and the side plate are located on the same side of the bottom plate 114.

[0069] In this way, the bottom plate 114 and the side plates are arranged to form a box body with a side opening 115a, and the packaging plate 113 is arranged at the side opening 115a of the box body, and can be assembled to form a box body 112 with an opening 115a, so that the box cover 111 can be covered on the opening 115a of the box body 112, thereby assembling to form a sealed shell 110.

[0070] Specifically, see Figure 4 As shown, the side panel may include a right side panel 112a, a left side panel 112b and a rear side panel 112c, wherein the right side panel 112a and the left side panel 112b are arranged opposite to each other, and the rear side panel 112c and the packaging panel 113 are arranged opposite to each other, and the right side panel 112a, the left side panel 112b, the rear side panel 112c and the packaging panel 113 are jointly arranged to form the side panel.

[0071] Also, see Figure 4As shown, in this embodiment, the side plate (right side plate 112a or left side plate b) may be provided with a first bent portion 1121 at the edge position facing the packaging plate 113, and the first bent portion 1121 may be provided with a fourth connection hole 1122, and the packaging plate 113 may also be provided with a fifth connection hole 1133, and the side plate and the packaging plate 113 are connected by a third fastener 1123 (see Figure 8 As shown) is threadedly matched with the fourth connecting hole 1122 and the fifth connecting hole 1133 to achieve connection between the two.

[0072] By setting a first bending portion 1121 on the edge of the side panel, and the fourth connection hole 1122 on the first bending portion 1121 corresponds to the fifth connection hole 1133 on the packaging plate 113, the fourth connection hole 1122 and the fifth connection hole 1133 are threadedly matched through the third fastener 1123, thereby realizing a threaded matching connection between the first bending portion 1121 on the edge of the side panel and the packaging plate 113, so as to improve the connection reliability between the side panel and the packaging plate 113, thereby improving the connection reliability between the box body of the box body 112 and the packaging plate 113 in this embodiment.

[0073] In one possible implementation, continue to refer to Figure 4 As shown, the bottom plate 114 may further be provided with a second bent portion 1142 at the edge position corresponding to the packaging plate 113. In addition, the second bent portion 1142 may further be provided with a sixth connection hole 1144, and the packaging plate 113 may further be provided with a seventh connection hole 1134. The side plate and the packaging plate 113 may be fastened together by a fourth fastener 1145 (see Figure 8 As shown) is threadedly matched with the sixth connecting hole 1144 and the seventh connecting hole 1134 to achieve connection between the two.

[0074] By setting a second bending portion 1142 on the edge of the bottom plate 114, and the sixth connection hole 1144 on the second bending portion 1142 corresponds to the seventh connection hole 1134 on the packaging plate 113, the sixth connection hole 1144 and the seventh connection hole 1134 are threadedly matched through the fourth fastener 1145, thereby realizing a threaded matching connection between the second bending portion 1142 on the edge of the bottom plate 114 and the packaging plate 113, so as to improve the connection reliability between the bottom plate 114 and the packaging plate 113, thereby improving the connection reliability between the box body of the box body 112 and the packaging plate 113 in this embodiment.

[0075] In addition, refer to Figure 5As shown, in this embodiment, the heat exchanger 130 may include a heat exchange portion 131, wherein at least one first connection hole 1321 may be respectively provided at both ends of the heat exchange portion 131, and the mounting plate 120 may include a main body, and at both ends of the main body may be respectively provided with at least one second connection hole 122 opposite to the first connection hole 1321, and the two ends of the mounting plate 120 and the heat exchanger 130 may be threadedly matched with the first connection hole 1321 and the second connection hole 122 through the first fastener 121 to achieve a threaded connection between the two.

[0076] In this way, the first connecting holes 1321 at both ends of the heat exchange part 131 of the heat exchanger 130 correspond to the second connecting holes 122 at both ends of the main body of the mounting plate 120. The first connecting holes 1321 and the second connecting holes 122 are threadedly matched through the first fastener 121 to realize the threaded matching connection between the heat exchanger 130 and the mounting plate 120, thereby improving the assembly efficiency between the heat exchanger 130 and the mounting plate 120.

A threaded assembly part 124 may be provided between the mounting plate 120 and the heat exchanger 130 to cooperate with the second assembly hole and the first assembly hole threads to achieve a threaded connection between the two.

[0079] In this way, the first assembly hole on the assembly plate 133 of the heat exchanger 130 corresponds to the second assembly hole on the mounting plate 120, and the first assembly hole and the second assembly hole are threadedly matched through the threaded assembly part 124, so that the threaded matching connection between the heat exchanger 130 and the mounting plate 120 in this embodiment can be realized, thereby improving the assembly reliability between the heat exchanger 130 and the mounting plate 120.

[0080] See also Figure 5 As shown, in this embodiment, the heat exchanger 130 may further include an input pipe 134 and an output pipe 135, wherein the first end of the input pipe 134 may be connected to the inlet on the heat exchange part 131, and the first end of the output pipe 135 may be connected to the outlet on the heat exchange part 131.

[0081] By arranging an input pipe 134 and an output pipe 135 on the heat exchange element, the input pipe 134 is connected to the inlet of the heat exchange part 131, and the output pipe 135 is connected to the outlet of the heat exchange part 131, so that the heat exchange part 131 of the heat exchanger 130 can be connected to the outside through the input pipe 134 and the output pipe 135. For example, external cold liquid can enter the interior of the heat exchange part 131 through the input pipe 134, and then the hot liquid generated after the cold liquid undergoes heat exchange can flow out from the output pipe 135 through the output pipe 135, thereby realizing the heat exchange function of the heat exchange element.

[0082] In addition, a first avoidance portion 1131 and a second avoidance portion 1132 may be provided on the packaging plate 113, wherein the input tube 134 may be passed through the first avoidance portion 1131, and the output tube 135 may be passed through the second avoidance portion 1132, and one end of the input tube 134 may be located inside the shell 110, and the other end of the input tube 134 may be located outside the shell 110, and one end of the output tube 135 may be located inside the shell 110, and the other end of the output tube 135 may be located outside the shell 110.

[0083] See also Figure 8 As shown, the number of the input tubes 134 on the left side can be two, and the number of the output tubes 135 on the right side can also be two. It can be understood that in a possible implementation, Figure 8 One of the two input pipes 134 on the left side can be used as an input pipe, and the other can be used as an output pipe. Figure 8 One of the two output pipes 135 on the right side can also be an input pipe, and the other can be an output pipe. In this way, two heat dissipation channels with opposite flow directions can be formed on the heat exchanger, ensuring effective heat exchange in the heat exchanger. In this application, the installation position and vertical number of input pipes 134 and 135 are not limited.

[0084] In addition, it should be noted that, in actual use, the assembly diagram of the box cover 111 and the box body 112 is as shown in FIG. Figure 9 As shown, the box cover 111 can be arranged above the box body 112.

[0085] In addition, it is understood that the box cover 111 and the box body 112 can be detachably connected. For example, the box cover 111 and the box body 112 can be connected by a threaded connection, a pin connection, or a snap connection, wherein this embodiment does not limit the specific structure of the detachable connection.

[0086] Of course, in some other embodiments, the box cover 111 and the box body 112 can be further connected in a non-detachable manner. For example, the connecting ends of the box cover 111 and the box body 112 are both made of metal, and the two can be connected by welding.

[0087] In addition, an embodiment of the present invention further provides an air conditioner, which may include the electric control box 100 described in the above embodiment. The specific structure and related effects of the electric control box 100 can refer to the above embodiment.

[0088] The air conditioner may be a central air conditioner or a wall-mounted air conditioner. For the convenience of description, the following embodiments are described as central air conditioners.

[0089] An air conditioner may include an indoor air conditioner unit and an outdoor air conditioner unit. For example, a central air conditioner may include an indoor air conditioner unit and an outdoor air conditioner unit. The indoor air conditioner unit and the outdoor air conditioner unit may be connected by a pipeline for the flow of heat exchange medium. The indoor air conditioner unit is usually installed indoors, and the outdoor air conditioner unit is usually installed outdoors. The indoor air conditioner unit and the outdoor air conditioner unit cool down the higher temperature heat exchange medium through the outdoor air conditioner to form a low-temperature heat exchange medium. The low-temperature heat exchange medium enters the indoor air conditioner unit through the pipeline to exchange heat with the indoor air, thereby reducing the temperature of the indoor air. The heat exchange medium after heat exchange returns to the outdoor air conditioner unit, and the cycle is repeated to achieve the purpose of cooling.

[0090] In this embodiment, the number of outdoor air conditioner units is usually one, while the number of indoor air conditioner units can be multiple. When there are multiple indoor air conditioner units, the outdoor air conditioner unit can be connected to all of the indoor air conditioner units via pipelines, and each indoor air conditioner unit is provided with one or more air outlets to discharge the cooled, heated, dehumidified, or purified air into the room through the air outlets.

[0091] During the cooling process of the central air conditioner, the heat exchanger of the indoor unit of the air conditioner is the evaporator, and the refrigerant in the evaporator absorbs heat from liquid to gas. In the process of refrigerant evaporation and heat absorption, the evaporator exchanges heat with the air flowing through the evaporator, taking away the heat in the air in the indoor unit of the air conditioner, so that the air discharged from the indoor unit of the air conditioner is the air that has released heat and cooled down, and the indoor unit of the air conditioner blows cold air. At the same time, the heat exchanger of the outdoor unit of the air conditioner is the condenser, and the refrigerant in the condenser changes from gas to liquid. In the process of refrigerant condensation and heat release, the condenser exchanges heat with the air in the outdoor unit of the air conditioner flowing through the condenser, so that the air in the outdoor unit of the air conditioner brings the heat of the condenser to the outside of the outdoor unit of the air conditioner, thus realizing the cooling process.

[0092] During the heating process of the air conditioner, the outdoor heat exchanger is the evaporator, and the refrigerant in the evaporator absorbs heat from liquid to gas. In the process of refrigerant evaporation and heat absorption, the evaporator exchanges heat with the air flowing through the evaporator, and replaces the heat carried by the air in the outdoor unit of the air conditioner with the refrigerant in the evaporator. At the same time, the indoor heat exchanger is the condenser, and the refrigerant in the condenser changes from gas to liquid. In the process of refrigerant condensation and heat release, the condenser exchanges heat with the air in the indoor unit of the air conditioner flowing through the condenser, so that the air in the indoor unit of the air conditioner takes away the heat carried by the condenser and discharges it from the indoor unit of the air conditioner to the room outside the indoor unit of the air conditioner, so that the indoor unit of the air conditioner blows hot air, thus realizing the heating process.

[0093] The air conditioner outdoor unit in an embodiment of the present invention may include the electronic control box and housing described in the above embodiment. The electronic control box is installed in the housing and is used to maintain the outdoor unit in operation. There are various ways to secure the electronic control box within the housing, including, for example, securing the electronic control box within the housing with screws, securing the electronic control box within the housing with snaps, or hanging the electronic control box within the housing with a hook.

[0094] Since the present air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described one by one here.

[0095] Figure 10 A schematic flow chart of a method for assembling an electric control box according to an embodiment of the present application.

[0096] Based on the above embodiments, Figure 10 As shown, the embodiment of the present invention further provides an assembly method of the electric control box 100. In this embodiment, the assembly method of the electric control box 100 may include the following steps:

[0097] S101 , providing a box body 112 , a box cover 111 , a mounting plate 120 , and a heat exchanger 130 , wherein the top end of the box body 112 has an opening 115 a .

[0098] See also Figure 1 As shown, a housing 110 consisting of a box cover 111 and a box body 112 is provided. After the housing 110 is assembled, the housing 110 can be a sealed housing. For example, the interior of the housing 110 is isolated from the exterior, and liquid and dust cannot enter the interior of the housing 110. With this arrangement, the electric control box 100 can achieve waterproof and dustproof properties, so that the electric control box 100 can operate normally even in harsh outdoor environments, thereby improving the reliability of the electric control box 100 and extending the service life of the electric control box 100.

[0099] Among them, see Figure 2As shown, the top of the box body 112 provided in the embodiment of the present application has an opening 115a. For example, the top of the box body 112 is open, and the box cover 111 is arranged on the opening 115a at the top of the box body 112. The box body 112 can be a square box body 112, a round box body 112, or other shapes. In the embodiment of the present application, the shape of the box body 112 includes but is not limited to a square, round, or oval shape. In the embodiment of the present application, the box body 112 can be specifically described as a square box.

[0100] It is understood that the box body 112 and the box cover 111 can be detachably connected. Before assembly, see Figure 3 As shown, the box cover 111 is detached from the box body 112, so that the top end opening 115a of the box body 112 is open.

[0101] Among them, see Figure 2 As shown, a mounting plate 120 is also provided, wherein the mounting plate 120 is specifically an electrical mounting plate, on which electrical components such as terminal blocks, reactors, and filters can be provided. In order to dissipate heat for the electronic components in the electrical control box 100, a heat exchanger 130 is also provided. The heat exchanger 130 can be a heat exchange tube, one end of the heat exchange tube being a refrigerant medium input tube, and the other end of the heat exchange tube being a refrigerant medium output tube, so that heat dissipation is achieved through the refrigerant medium.

[0102] S102 , fixing the mounting plate 120 and the heat exchanger 130 by screw connection.

[0103] See also Figure 5 As shown, the mounting plate 120 and the heat exchanger 130 can be two independent components. Figure 6 As shown, the mounting plate 120 and the heat exchanger 130 are fixed. For example, the mounting plate 120 and the heat exchanger 130 can be connected by a threaded connection. For example, a connecting piece 132 can be provided at both ends of the heat exchanger 130, and a first connecting hole 1321 is provided on the connecting piece 132. In addition, a second connecting hole 122 is provided at a position corresponding to the first connecting hole 1321 on the mounting plate 120. The first fastener 121 passes through the second connecting hole 122 and is screwed into the first connecting hole 1321. In this way, under the threaded cooperation between the first fastener 121 and the first connecting hole 1321 and the second connecting hole 122, the mounting plate 120 and the heat exchanger 130 can be fixed as an integral structure.

[0104] In order to fix the middle position of the mounting plate 120 and the heat exchanger 130, an assembly plate 133 may be further provided on the heat exchanger 130, wherein the assembly plate 133 may be provided with a first assembly hole, and in addition, the mounting plate 120 may be provided with a second assembly hole. In this way, when the first assembly hole and the second assembly hole are relative to each other, the threaded assembly part 124 is threadedly connected with the second assembly hole and the first assembly hole to fix the middle position of the mounting plate 120 and the heat exchanger 130. In this way, both ends and the middle position of the mounting plate 120 and the heat exchanger 130 are fixed, so that a more reliable connection is achieved between the heat exchanger 130 and the mounting plate 120, thereby avoiding looseness between the heat exchanger 130 and the mounting plate 120, which may cause the position of components in the electrical control box 100 to be offset or damaged by collision during transportation.

[0105] S103 , placing the fixed mounting plate 120 and the heat exchanger 130 in the box body 112 .

[0106] See also Figure 7 As shown, the fixed heat exchanger 130 and the mounting plate 120 as a whole are placed into the box body 112 through the top opening 115 a of the box body 112 .

[0107] It can be understood that since the input pipe 134 and the output pipe 135 are provided at both ends of the heat exchanger 130, when the fixed heat exchanger 130 and the mounting plate 120 are installed downward from the top opening 115a of the box body 112, the input pipe 134 and the output pipe 135 will block the assembly. Therefore, in the embodiment of the present application, as shown in Figure 4, one side of the box body 112 has a side opening 115a, so that the side opening 115a can play a role in avoiding the assembly of the input pipe 134 and the output pipe 135.

[0108] In the above step S101, when providing the box body 112, the following steps may be included:

[0109] Step a: providing side panels (which may be the right panel 112a, the left panel 112b, and the rear panel 112c), the bottom panel 114, and the packaging panel 113, and forming a first avoidance portion 1131 and a second avoidance portion 1132 on the assembly panel 133;

[0110] Step b: The side panels are arranged around a portion of the edge of the bottom panel 114 to form a side opening 115 a on the side of the box body 112 .

[0111] Step c: The packaging plate 113 is assembled at the side opening 115 a . The packaging plate 113 , the side plate and the bottom plate 114 form a receiving cavity 115 with an open top.

[0112] In this way, the provided box body 112 may have a side opening 115 a . It is understood that, before assembly, the packaging plate 113 may be moved away from the side opening 115 a to open the side opening 115 a .

[0113] Thus, when executing step S103, the fixed mounting plate 120 and the heat exchanger 130 are placed in the box body 112 through the opening 115a of the box body 112, and the side opening 115a avoids the input pipe 134 and the output pipe 135 of the heat exchanger 130, see Figure 7 As shown, the input pipe 134 of the heat exchanger 130 and the output pipe 135 of the heat exchanger 130 extend outward from the side opening 115a.

[0114] S104 , fixing the mounting plate 120 and the box body 112 by screw connection.

[0115] See also Figure 7 As shown, after the mounting plate 120 and the heat exchanger 130 are placed in the box body 112, in order to fix the entire structure to the box body 112, a second fastener 125 is used to connect with the threaded hole on the bottom plate 114 of the box body 112 (see Figure 4 ) cooperate to fix the mounting plate 120, the heat sink and the box body 112, so that the overall structure of the mounting plate 120 and the heat sink is fixed in position inside the box body 112. During transportation or use, the overall structure of the mounting plate 120 and the heat sink is not prone to positional displacement inside the box body 112, causing poor circuit contact.

[0116] S105 , placing the box cover 111 on the box body 112 , and connecting the box cover 111 to the box body 112 .

[0117] It is understandable that in the above step S103, the packaging plate 113 is assembled after being removed from the side opening 115a. Therefore, in the embodiment of the present application, before the box cover 111 is covered on the box body 112, see Figure 8 As shown, it also includes: setting the packaging plate 113 at the side opening 115a position, and connecting the packaging plate 113 to the side plate, and the input pipe 134 of the heat exchanger 130 and the output pipe 135 of the heat exchanger 130 can be respectively passed through the first avoidance portion 1131 and the second avoidance portion 1132.

[0118] See also Figure 9 As shown, the box cover 111 can be placed on the top of the side plate and the packaging plate 113, and the box cover 111 is fastened to the top of the packaging plate 113 and the side plate by screws. This completes the assembly of the electric control box 100.

[0119] It should be noted that, in the embodiment of the present application, the box cover 111 and the packaging plate 113 are independent structures. In a possible implementation, the box cover 111 and the packaging plate 113 can also be used as an integral structure. For example, the box cover 111 and the packaging plate 113 are an integrally molded part. In this way, after step S104, the integral structure formed by the box cover 111 and the packaging plate 113 can be installed on the box body 112 at one time, thereby reducing the one-time assembly process.

[0120] Alternatively, in another possible implementation, the three side panels (left panel 112b, right panel 112a and rear panel 112c) of the box body 112 can also be formed into an integral structure with the box cover 111, so that the box cover 111 and the box body 112 form a shell 110 with a side opening 115a, and the packaging plate 113 is detachably connected at the side opening 115a. In this way, when step S103 is executed, the fixed mounting plate 120 and the heat exchanger 130 can be horizontally assembled into the shell 110 from the side opening 115a, and finally, the packaging plate 113 is assembled to the side opening 115a to complete the assembly of the electrical control box 100. It should be noted that when the heat exchanger and the mounting plate 120 are fixed as an integral structure and assembled from the side opening 115a, since there is no opening 115a at the top of the shell 110, the mounting plate 120 and the box body 112 often cannot be fixed in the vertical direction, but the mounting plate 120 and the heat exchanger 130 can be fixed in the horizontal direction to the packaging plate 113 or the side plate respectively.

[0121] It should be noted that, Figure 8 In the embodiment, when the input pipe 134 and the output pipe 135 of the heat exchanger 130 are passed through the first avoidance portion 1131 and the second avoidance portion 1132, in order to ensure the sealing of the electric control box 100, the input pipe 134 and the output pipe 135 are sealed between the first avoidance portion 1131 and the second avoidance portion 1132 respectively. For example, sealing members (such as sealant) are provided between the input pipe 134 and the output pipe 135 and the first avoidance portion 1131 and the second avoidance portion 1132 respectively.

[0122] The assembly method of the electrical control box 100 provided in the embodiment of the present application is to fix the mounting plate 120 and the heat exchanger 130. Specifically, the mounting plate 120 and the heat exchanger 130 are fixed by means of a threaded connection. In this way, during assembly, the corresponding positions of the connecting holes between the mounting plate 120 and the heat exchanger 130 are fixed, so that the mounting plate 120 and the heat exchanger 130 can be assembled automatically, thereby improving the assembly efficiency of the mounting plate 120 and the heat exchanger 130. In addition, the mounting plate 120 and the box body 112 are fixed. Specifically, the mounting plate 120 and the box body 112 are fixed by means of a threaded connection. Since the threaded holes and the corresponding positions of the threaded holes between the mounting plate 120 and the box body 112 are fixed, automated assembly can be achieved, and finally the automated assembly of the electrical control box 100 is achieved, thereby improving the assembly efficiency of the electrical control box 100.

[0123] Figure 11 Another flow chart of the assembly method of the electric control box 100 provided in the embodiment of the present application. Figure 11 As shown, the embodiment of the present invention further provides an assembly method of the electric control box 100. In this embodiment, the assembly method of the electric control box 100 may include the following steps:

[0124] S201 , providing a box body 112 , a box cover 111 , a mounting plate 120 and a heat exchanger 130 , wherein the top end of the box body 112 has an opening 115 a .

[0125] This step can refer to step S101 in the above embodiment and will not be described in detail in the embodiment of the present application.

[0126] S202 , installing the heat exchanger 130 in the box body 112 .

[0127] It is understood that the difference from the above-mentioned step S102 is that in S202, the heat exchanger 130 is first installed in the box body 112. The heat exchanger 130 can be placed in the box body 112 through the top opening 115a of the box body 112. During assembly, it is understood that since the heat exchanger 130 is provided with an input pipe 134 and an output pipe 135 at both ends, when the fixed heat exchanger 130 and the mounting plate 120 are installed downward from the top opening 115a of the box body 112, the input pipe 134 and the output pipe 135 will block the assembly. Therefore, in the embodiment of the present application, as shown in Figure 4, a side opening 115a is provided on one side of the box body 112. In this way, the side opening 115a can play a role in avoiding the assembly of the input pipe 134 and the output pipe 135.

[0128] In the above step S101, when providing the box body 112, the following steps may be included:

[0129] Step a: providing side panels, a bottom panel 114 , and a packaging panel 113 , and forming a first avoidance portion 1131 and a second avoidance portion 1132 on an assembly panel 133 ;

[0130] Step b: The side panels are arranged around a portion of the edge of the bottom panel 114 to form a side opening 115 a on the side of the box body 112 .

[0131] Step c: The packaging plate 113 is assembled at the side opening 115 a . The packaging plate 113 , the side plate and the bottom plate 114 form a receiving cavity with an open top.

[0132] In this way, the provided box body 112 may have a side opening 115 a . It is understood that, before assembly, the packaging plate 113 is moved away from the position of the side opening 115 a so that the side opening 115 a is opened.

[0133] Thus, when executing step S102, the heat exchanger 130 can be placed downward from the top opening 115a and the side opening 115a of the box body 112 so as to be placed inside the box body 112, and the side opening 115a can avoid the input pipe 134 and the output pipe 135, so that the input pipe 134 and the output pipe 135 on the heat exchanger 130 can extend outward from the side opening 115a (see Figure 7 ).

[0134] S203 , installing the mounting plate 120 in the box body 112 and locating it above the heat exchanger 130 .

[0135] It is understandable that the mounting plate 120 is placed into the box body 112 from the top opening 115a of the box body 112. Since the heat exchanger 130 is first assembled in the box body 112, after the mounting plate 120 is placed in the box body 112, the mounting plate 120 is located on the heat exchanger 130.

[0136] S204 , fixing the mounting plate 120 and the heat exchanger 130 by screw connection.

[0137] In the above step S102, the heat exchanger 130 and the mounting plate 120 are fixed before being placed in the box body 112, and in step S204, the mounting plate 120 and the heat exchanger 130 placed in the box body 112 are fixed. The mounting plate 120 and the heat exchanger 130 can be fixed in the same manner as in the above step S102, which will not be repeated in the embodiment of the present application.

[0138] The mounting plate 120 and the heat exchanger 130 are fixed by being screwed together, so that automated assembly can be achieved and assembly efficiency is improved.

[0139] S205 , fixing the mounting plate 120 and the box body 112 by screw connection.

[0140] In step S205, the specific method for securing the mounting plate 120 and the housing 112 can be found in step S104. Thus, the mounting plate 120, the heat exchanger 130, and the housing 112 are secured, completing the assembly of the mounting plate 120 and the heat exchanger 130. The threaded connection between the mounting plate 120 and the housing 112 allows for automated assembly, improving assembly efficiency.

[0141] S206 , placing the box cover 111 on the box body 112 , and connecting the box cover 111 to the box body 112 .

[0142] In step S206 , the box cover 111 is placed on the box body 112 , and the box cover 111 and the box body 112 are connected. Please refer to the above step S105 .

[0143] It should be noted that, in this embodiment, when executing the above steps S204 and S205, step S205 may be executed first and then step S204, or, in one implementation, step S204 and step S205 may be executed simultaneously, which improves assembly efficiency.

[0144] It can be understood that in the embodiment of the present application, the method of assembling horizontally from the side opening 115a into the box body 112 can also be adopted. For example, the heat exchanger 130 can be first assembled horizontally from the side opening 115a into the box body 112, and then the mounting plate 120 can also be assembled horizontally from the side opening 115a into the box body 112, and finally the packaging plate 113 can be assembled to the side opening 115a, and the box cover 111 can be assembled to the box body 112.

[0145] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0146] In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention.
