Detailed Description
The electrical control box generally includes a box body, and a mounting plate and a plurality of electrical components disposed in the box body, the plurality of electrical components being disposed on a mounting surface of the mounting plate. In the related art, there is often a technical problem that the volume of the electric control box is large. The reason is that the types of the electric components in the electric control box are different, the space in the box body is also different, and the outer contour size of the electric components can be changed according to the different specifications and models of the selected components. Therefore, when the electrical components are arranged on the mounting plate, the problem that the electrical components occupy a large space due to unreasonable arrangement, so that the volume of the electrical control box is overlarge, can occur.
In view of this, in the embodiment of the present invention, with attention paid to the actual space occupied by each electrical component in the electrical control box, the circuit board assemblies with larger occupied space are arranged side by side, and then the circuit board assemblies with smaller occupied space are arranged on the side of the circuit board assemblies to cooperate with the arrangement of the circuit board assemblies, so that the occupied space of all the electrical components in the box body is effectively reduced, and the volume of the electrical control box body is smaller.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic view of an internal structure of an electronic control box 100 according to an embodiment of the present invention, and fig. 2 is a schematic view illustrating a relative positional relationship between electrical components in the electronic control box 100 according to the embodiment of the present invention. In fig. 2, the block-shaped electrical component module of each electrical component shown in fig. 1 is illustrated for clarity of the relative positional relationship of each electrical component, and it is understood that the specific shape of the electrical component module does not limit the specific shape of each electrical component in the present invention, and the distance between the electrical component modules does not limit the specific pitch of each electrical component in the present invention.
Referring to fig. 1 and 2, the electrical control box 100 provided by the present invention includes a box body 110. The box body 110 has an inner cavity, in other words, an accommodating cavity is formed inside the box body 110.
The electronic control box 100 of the embodiment of the present application may be, for example, a sealed electronic control box. Therefore, other foreign matters such as water drops and dust can be prevented from entering the electric control box 100 to damage electronic elements in the electric control box 100, and the waterproof, dustproof and anticorrosion effects are achieved.
In the embodiment of the present invention, for convenience of description, the directions in the electronic control box 100 are defined as follows:
the first direction F and the second direction S of the box 110 are perpendicular to each other, for example, the first direction F may be a maximum dimension direction of the box 110, the maximum dimension direction of the box 110 is generally a maximum dimension direction of the mounting plate 150, and may be a length direction of the box 110, the second direction S may be a width direction of the box 110, and a plane formed by the first direction F and the second direction S may be parallel to a plate surface of the mounting plate. The thickness direction H is a direction perpendicular to both the first direction and the second direction of the box body 110, and is also a height direction of the box body 110, and the thickness direction H of the box body 110 is perpendicular to a plate surface of the mounting board for mounting the electrical component.
The box body 110 may include a bottom wall 111 and a side wall 112 surrounding and connected to the periphery of the bottom wall 111, in detail, the bottom end of the side wall 112 is connected to the circumferential edge of the bottom wall 111, and the top end of the side wall 112 extends away from the bottom wall 111, and in fact, the side wall 112 and the bottom wall 111 may together form a hood-shaped member. The box body 110 may further include a box cover (not shown) that covers the top opening of the cover-shaped member, so that the box cover, the bottom wall 111 and the side wall 112 together define the accommodating cavity. Of course, the accommodating cavity is a closed cavity.
In an embodiment of the present invention, referring to fig. 1 and 2, the electrical control box 100 further includes a mounting plate 150 and a plurality of electrical components, which may be disposed on the mounting plate 150, for example, a plurality of electrical components may be disposed on a top end surface of the mounting plate 150, or some electrical components may be disposed on a bottom end surface of the mounting plate 150. Thus, the mounting board 150 provided with a plurality of electrical components can be accommodated in the accommodating chamber described above.
For example, a plurality of mounting brackets (not shown) may be provided on an inner side surface of the bottom wall 111 facing the receiving cavity, and the mounting plate 150 may be fixed to top ends of the mounting brackets by fasteners or the like. Of course, in the case where the electrical components are also provided on the bottom end face of the mounting board 150, it is necessary to make the mounting bracket have a certain height in the thickness direction H so as to ensure that there is a sufficient space between the mounting board 150 and the bottom wall 111 to accommodate the electrical components.
It is to be noted that, when the mounting board 150 provided with the electrical components is fixed to the bottom wall 111, the side wall 112 at least partially surrounds the plurality of electrical components in the thickness direction H.
Each of the plurality of electrical components may include at least one electrical element that, in combination, may perform a predetermined function.
In an embodiment of the present invention, the plurality of electrical components may include a non-circuit board assembly 130 and at least two circuit board assemblies 120.
Here, each circuit board assembly 120 may include at least one circuit board, that is, electrical components implementing a predetermined function may be disposed on the circuit board, and the circuit board assembly 120 may include one or more circuit boards according to the implemented function. While the electrical components not included in circuit board assembly 130 are not disposed on the circuit board, they may be disposed directly on mounting board 150, for example.
In the embodiment of the utility model, the circuit board assemblies 120 are arranged side by side in the box body 110, and at least a part of the non-circuit board assemblies 130 are arranged on the side of the circuit board assemblies 120.
Here, the side-by-side arrangement means that at least two circuit board assemblies 120 are arranged in a row in a predetermined direction of the case 110, for example, in the first direction, and the circuit board assemblies 120 are not limited to be completely aligned in the thickness direction H, and there may be a slight difference in height between the circuit board assemblies 120 in the thickness direction H. In addition, the arrangement in one row means that the circuit board assemblies 120 are substantially aligned in one row, and the circuit board assemblies 120 are not necessarily perfectly aligned in a direction perpendicular to the predetermined direction. Also, the fact that at least a part of the non-circuit board assemblies 130 are disposed to the side of the circuit board assemblies 120 means that at least a part of the non-circuit board assemblies 130 are located to the circumferential side of the circuit board assemblies 120 in a plane (which is parallel to the plate surface direction of the mounting board) constructed by the first direction F and the second direction S, which includes a case where the non-circuit board assemblies 130 are located at the circumferential edges of all the circuit board assemblies 120 or the non-circuit board assemblies 130 are located in the gaps between the adjacent circuit board assemblies 120.
Generally, the circuit board assembly 120 includes a plurality of circuit boards, where the circuit boards have a larger area in the horizontal direction due to the layout of the electrical components, which occupies a larger space in the box body 110 of the electrical control box 100, especially occupies a larger area on the mounting surface of the mounting plate 150.
On the contrary, the occupied space of the non-circuit board assembly 130 is relatively small, but the circuit board assemblies 120 are arranged in the box body 110 side by side, and the non-circuit board assembly 130 is arranged on the side of the circuit board assembly 120, so that the arrangement problem of the circuit board assemblies 120 with large occupied space is solved firstly, and then the positions of the non-circuit board assemblies 130 are flexibly arranged according to the relative positions of the circuit board assemblies 120 and the actual occupied conditions of the accommodating cavities in the box body 110, therefore, the gaps among the circuit board assemblies 120 can be fully utilized, the arrangement of a plurality of electric assemblies can be compact and reasonable as much as possible, and the space utilization rate in the box body 110 is improved.
Referring to fig. 2, in order to further improve the reasonableness of the layout, at least two circuit board assemblies 120 each have circuit boards that may be arranged side by side in sequence in the direction of the maximum size of the case 110.
Here, the maximum dimension direction may be, for example, a length direction of the case 110, that is, the first direction F, and generally, the length direction of the case 110 is the maximum dimension direction of the case 110, and the plurality of circuit boards are arranged along the length direction of the case 110, so that the space in the case 110 can be fully utilized.
The side-by-side arrangement of the circuit boards is similar to the side-by-side arrangement of the circuit board assemblies 120, and the side-by-side arrangement of the circuit boards means that at least two circuit boards are arranged in a row in the predetermined direction of the mounting board 150, and of course, the row in the row means that the circuit boards are substantially arranged in a row, and the circuit boards are not necessarily completely aligned in the direction perpendicular to the predetermined direction.
The detailed layout of the electrical components in the box 110 is described below.
Referring to fig. 1 and 2, the at least two circuit board assemblies 120 may include a main control circuit board assembly 121, a fan control circuit board assembly 122, and a compressor control circuit board assembly 123. The main control circuit board assembly 121, the fan control circuit board assembly 122, and the compressor control circuit board assembly 123 may each include one circuit board, or may also include two or three circuit boards, or other number of circuit boards, according to the actual arrangement requirement. In the present invention, the number of circuit boards included in the three electrical components is not limited. The main control circuit board assembly 121 is used for performing coordinated control on various electrical components in the electrical control box 100, the fan control circuit board assembly 122 is used for controlling a fan in the air conditioner, and the compressor control circuit board assembly 123 is used for controlling a compressor in the air conditioner.
Alternatively, in another possible approach, the at least two circuit board assemblies 120 further include a filter circuit board assembly 124.
The filter circuit board assembly 124 includes at least two circuit boards, and the number of the circuit boards included in the filter circuit board assembly 124 may be selected according to actual needs, and may be three, four or more. The filter circuit board assembly 124 is used to filter a strong electric input from an external power source.
For the arrangement of the main control circuit board assembly 121, the fan control circuit board assembly 122 and the compressor control circuit board assembly 123, the following manners may be adopted:
that is, the circuit boards included in the main control circuit board assembly, for example, the main control circuit board 1211 and the circuit boards included in the blower control circuit board assembly 122 have different heights in the thickness direction of the case 110, and the main control circuit board and the circuit boards included in the compressor control circuit board assembly 123 have different heights in the thickness direction. Here, the circuit board included in the main control circuit board assembly is not limited to the main control circuit board 1211, and may also be another type of circuit board, and similarly, in the case of another type of circuit board, it is not described herein again.
In detail, the height of the main control circuit board 1211 in the thickness direction may be greater than the height of the circuit board included in the fan control circuit board assembly 122 in the thickness direction. The height of the main control circuit board 1211 in the thickness direction may be greater than the height of the circuit board included in the compressor control circuit board assembly 123 in the thickness direction. Of course, the board surface directions of the circuit boards included in the plurality of electrical components are all parallel, and the setting height of the circuit board included in the fan control circuit board component 122 in the thickness direction is the same as the setting height of the circuit board included in the compressor control circuit board component 123 in the thickness direction.
As such, in practice, the distance between the main control circuit board assembly 121 and the mounting plate 150 is greater than the distance between the fan control circuit board assembly 122 and the compressor control circuit board assembly 123. In an actual operating scenario, the main control circuit board assembly 121 is set higher.
For example, referring to fig. 2 and 3, the main control circuit board assembly 121 includes a main control board bracket 1212, and the main control circuit board 1211 may be supported at a top end of the main control board bracket 1212, so that the main control circuit board bracket 1212 supports the main control circuit board 1211 on the mounting plate 150, and thus the mounting plate 150 and the circuit board included in the main control circuit board assembly 121 may have an accommodation gap in a thickness direction. The receiving gap may be used to receive a portion of the electrical component.
For example, the at least two circuit board assemblies 120 of the present invention further include a fuse circuit board assembly 125, and the fuse circuit board assembly 125 can be received in the receiving gap.
It should be noted that the fuse circuit board assembly 125 is generally connected to an external power source, so that the fuse circuit board assembly 125 as a strong electric component needs to be separated from the main control circuit board assembly 121 as a weak electric component to avoid interference with each other. In the above scheme, the fuse circuit board assembly 125 is disposed on the mounting plate 150, and the main control circuit board assembly 121 is disposed on the top of the fuse circuit board assembly 125 in a suspended manner, so that strong current and weak current can be distinguished from each other, thereby preventing the strong current from interfering with the weak current, and controlling the main control circuit board assembly 121 more accurately.
On the basis of the above scheme, the non-circuit board assembly 130 includes the wire holder 132, and the wire holder 132 is located on a side of the main control circuit board assembly 121 facing away from the first fan 141. The fuse circuit board assembly 125 may be electrically connected to an external power source through a wire holder 132. The wire holder 132 may have a partial structure that is also located in the receiving space.
In addition, the main control circuit board assembly 121, the filter circuit board assembly 124, the fan control circuit board assembly 122, and the compressor control circuit board assembly 123 may be sequentially arranged side by side in the first direction.
As previously described, filter circuit board assembly 124 includes at least two circuit boards, and filter circuit board assembly 124 illustratively includes a filter circuit board 1241 and a relay circuit board 1242. Here, the filter circuit board 1241 and the relay circuit board 1242 may be arranged side by side in the second direction S. It should be noted that, regarding the mutual positional relationship between the filter circuit board 1241 and the relay circuit board 1242 in the second direction S, fig. 2 illustrates that the filter circuit board 1241 is located on the rear side of the relay circuit board 1242 (corresponding to the upper right direction in the drawing of fig. 2), and of course, the filter circuit board 1241 may be located on the front side of the relay circuit board 1242 (corresponding to the lower left direction in the drawing of fig. 2), which is not limited in this respect.
In the above solution, the relay circuit board 1242 has a larger margin besides the plurality of relays provided thereon, so that the control electrical elements are added to the electrical control box 100 according to the requirement during the actual use process. The control electric elements may include sensors, chips, various terminals, etc., so that the relay circuit board 1242 has a function of an expansion board. In the embodiment of the present invention, the relay circuit board 1242 is disposed at the side of the main control circuit board assembly 121, so that when other control functions need to be added, corresponding control electrical elements are disposed on the relay circuit board 1242.
In the embodiment of the present invention, the non-circuit board assembly 130 may further include a reactor 131, and the reactor 131 may be disposed on the same side of the fan control circuit board assembly 122 and the compressor control circuit board assembly 123.
Among them, the reactor 131 functions to filter and current-limit the output from the filter circuit board assembly 124.
Illustratively, the reactor 131 is provided on the upper side (with reference to the direction in the drawing plane of fig. 1) of the fan control circuit board assembly 122 and the compressor control circuit board assembly 123. Of course, the present invention is not limited thereto, and the reactor 131 may be provided on the lower side (with reference to the direction in the drawing of fig. 1) of the fan control circuit board assembly 122 and the compressor control circuit board assembly 123
In addition, the non-circuit board assembly 130 may further include a heat dissipation unit, and since the sealed box body 110 is a sealed space, each electrical component generates heat during operation, and the heat dissipation unit is required to be disposed to dissipate heat in the sealed accommodating cavity.
The heat dissipation unit may include a first fan 141, and the first fan 141 may be located at one side of the main control circuit board assembly 121, for example, such that the first fan 141 and the reactor 131 are located at the same side of the mounting plate 150, and it is ensured that the filter circuit board 1241 and the reactor 131 are sequentially disposed on an air outlet path of the first fan 141.
This is because the filter circuit board 1241 and the reactor 131 are both electrical components that generate heat more seriously, and as described above, the filter circuit board 1241 and the reactor 131 are sequentially disposed on the air outlet path of the first fan 141, and even the filter circuit board 1241 and the reactor 131 are disposed in close proximity to the air outlet of the first fan 141, so that the filter circuit board 1241 and the reactor 131 can be cooled by the cooling air blown by the first fan 141 at the first time, and the cooling effect is good.
It can be understood that, in order to make the cooling effect of the heat dissipating unit better, on the basis of the above solution, the inner cavity of the box body 110 may include the first side wall 1121, and the first side wall 1121 may be disposed at a position opposite to the first fan 141.
The first fan 141 is configured to blow cooling airflow toward the first side wall 1121, and for example, the air outlet side of the first fan 141 may be directed toward the first side wall 1121.
Also, the filter circuit board 1241 and the reactor 131 are located between the air outlet side of the first fan 141 and the first side wall 1121, and referring to a dotted arrow shown in fig. 2, the first side wall 1121 is provided to guide the cooling air flow passing through the filter circuit board 1241 and the reactor 131 to the compressor control circuit board assembly 123 and the fan control circuit board assembly 122. The compressor control circuit board assembly 123 and the fan control circuit board assembly 122 belong to electrical components with less heat generation, and when the cooling airflow with increased temperature flowing through the filter circuit board 1241 and the reactor 131 is guided by the first side wall 1121 to flow to the electrical components with less heat generation, the cooling airflow is appropriately cooled by the electrical components with less heat generation, is sucked by the first fan 141, and is blown to the electrical components with more heat generation, such as the filter circuit board 1241 and the reactor 131, by the first fan 141 again, so that a reciprocating heat dissipation cycle is performed.
Of course, more fans may be included in the heat dissipation unit, for example, the heat dissipation unit may further include a second fan 142, the second fan 142 is located between the first sidewall 1121 and the compressor pcb assembly 123, and an air outlet side of the second fan 142 faces the compressor pcb assembly 123. In this way, when the cooling airflow having an increased temperature flowing through the filter circuit board 1241 and the reactor 131 flows to the first side wall 1121, the cooling airflow can be accelerated by the second fan 142 to flow toward the compressor control circuit board assembly 123 and the fan control circuit board assembly 122, so that the heat dissipation effect is improved.
In addition, the non-circuit board assembly 130 may further include a transformer 133 and a power supply assembly 134, wherein the transformer 133 is disposed between the fan control circuit board assembly 122 and the relay circuit board 1242, and the transformer 133 may be used to control opening and closing of a windshield of an outdoor unit of an air conditioner included in the air conditioner. The power supply assembly 134 is located at a side of the main control circuit board assembly 121, and may provide control power for the main control circuit board assembly 121, or the fan control circuit board assembly 122, the compressor control circuit board assembly 123, and the like.
In an embodiment of the present invention, an air conditioner is further provided, where the air conditioner may include an indoor unit and an outdoor unit connected to each other, the outdoor unit is communicated with the indoor unit through a pipeline for flowing a heat exchange medium, and the electric control box 100 is located in the outdoor unit to control operation of a host in the outdoor unit.
Wherein the air conditioner can be a central air conditioner, the indoor unit of the air conditioner is arranged indoors, the outdoor unit of the air conditioner is arranged outdoors,
in the refrigeration process, the air conditioner outdoor unit is used for cooling the heat exchange medium with higher temperature to form a low-temperature heat exchange medium, the low-temperature heat exchange medium enters the air conditioner indoor unit through a pipeline to exchange heat with indoor air, the temperature of the indoor air is reduced, the heat exchange medium after heat exchange returns to the air conditioner outdoor unit again, and the purpose of cooling is achieved through circulation.
Specifically, the outdoor unit of an air conditioner may include a main unit and the electronic control box 100 in the technical solution of the foregoing embodiment, and the electronic control box 100 may be disposed inside the main unit to control the operation of the main unit.
