[0034] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0035] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0036] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] The present application provides an outdoor unit 1 and HVAC equipment of an embodiment, the HVAC equipment including but not limited to air conditioners, multi-split units, heat pumps, water heaters, swimming pool units, etc. Taking the HVAC equipment with the heating medium as refrigerant and the heating object as water as an example, the HVAC equipment includes an outdoor unit 1 and an indoor unit forming a refrigerant circulation flow path with the outdoor unit 1.

[0039] Specifically, the indoor unit may include components such as a heat exchanger, a water pump, an electric heating device, and an energy storage water tank, which are connected by water pipes to form a water circulation flow path. The heat exchanger has two inlets and two outlets, one set of interconnected inlets and outlets for the refrigerant to pass through, and the other set of interconnected inlets and outlets for the water medium to pass through. When the water medium flows through the heat exchanger, the refrigerant in the heat exchanger contacts the water, thereby heating and raising the temperature of the water. The water pump provides power for the circulation of water. The electric heating device can reheat the water heated by the heat exchanger and transport it to the energy storage water tank through a water pipe, thereby meeting the heating needs of the user.

[0040] The outdoor unit 1 may include components such as an evaporator, a compressor, a heat exchanger, and an expansion valve, which are connected in a circular manner through a refrigerant pipe. When the HVAC equipment is working, the refrigerant in the evaporator absorbs heat from the air and becomes a high-temperature, low-pressure gas; then the high-temperature gas is compressed by the compressor, so that the refrigerant forms a high-temperature, high-pressure liquid; the high-temperature, high-pressure liquid exchanges heat with the water in the water circulation flow path through the heat exchanger, so that the water temperature in the water circulation flow path increases, and the refrigerant becomes a low-temperature, high-pressure liquid; the low-temperature, high-pressure liquid is converted into a low-temperature, low-pressure gas through the expansion valve, and then circulates to the evaporator again, thus completing the refrigerant circulation process.

[0041] by Figure 1 For example, in the following description, Figure 1 The coordinate system in , defines the up-down direction ZZ, the front-back direction YY and the left-right direction XX, and the up-down direction ZZ, the front-back direction YY and the left-right direction XX are arranged perpendicular to each other in pairs.

[0042] See also Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic structural diagram of the outdoor unit 1 of the present application from a first perspective; Figure 2 This is a structural schematic diagram of the outdoor unit 1 of the present application from a second viewing angle; Figure 3 This is a schematic diagram of the internal structure of the outdoor unit 1 of the present application from a first perspective; the outdoor unit 1 includes a housing assembly 100, a wind wheel (not shown), a compressor (not shown), a heat exchanger 700, a mounting frame 200, and an electric control board assembly 300. During operation, the compressor is used to provide power to drive the refrigerant circulation, the refrigerant exchanges heat with the external air through the heat exchanger 700, the wind wheel accelerates the airflow into the heat exchanger 700, and the electric control board assembly 300 is used to control the operation of the compressor and the wind wheel.

[0043] Among them, a wind wheel cavity 130 and a compressor cavity 140 are arranged inside the shell assembly 100. The shell assembly 100 includes an outer shell 110 and a middle partition 120, and the outer contour of the outer shell 110 can be roughly rectangular. The outer shell 110 includes a chassis 112 and an upper shell 111. The lower end of the chassis 112 is fixedly connected with a support foot 113, and the support foot 113 is used to support the outdoor unit 1 on the ground, or to support it on a wall or the ground through a bracket (not shown in the figure), so as to achieve stable installation of the outdoor unit 1. The upper shell 111 includes a top cover 1111, a front panel 1112 and two side panels 1113, etc. The two side panels 1113 are arranged at intervals in the left-right direction XX, defining the outline of the upper shell 111 in the length direction; the front panel 1112 is arranged at the front end of the two side panels 1113 along the front-back direction YY, the top cover 1111 is generally arranged above the two side panels 1113 and the front panel 1112, and extends along the front-back direction YY, and the top cover 1111 is connected to the two side panels 1113 on both sides along the left-right direction XX; in this way, the top cover 1111, the two side panels 1113 and the front panel 1112 are spliced ​​to form the upper shell 111. It can be understood that in order to improve the air intake efficiency of the outdoor unit 1, thereby improving the heat exchange efficiency, the side panels 1113 can be designed as a grille form, so that air circulation can be facilitated. The upper shell 111 is installed on the chassis 112 and wrapped along the periphery of the chassis 112, so that the upper shell 111 and the chassis 112 are surrounded to form a receiving cavity (not shown in the figure).

[0044] The middle partition 120 is installed on the chassis 112. The middle partition 120 is located in the accommodating cavity and divides the accommodating cavity into a wind wheel cavity 130 and a compressor cavity 140 in the left and right directions. Figure 3 As shown in the example, the wind wheel cavity 130 is located on the left side of the middle partition 120, and the compressor cavity 140 is located on the right side of the middle partition 120. The heat exchanger 700 is mounted on the chassis 112 and arranged opposite to the air inlet of the outdoor unit 1, and the wind wheel is arranged opposite to the air outlet mask of the front panel 1112. It can be understood that the wind wheel and the heat exchanger 700 are arranged in the wind wheel cavity 130, the compressor is mounted on the chassis 112 and located in the compressor cavity 140, and the compressor includes a compressor body and its piping, and may also include a liquid reservoir, an accumulator, etc.

[0045] The heat exchanger 700 is substantially in an "L" shape, so that it has a large heat exchange area. Figure 5 In some structural forms, in order to facilitate the connection between the middle partition 120 and the shell assembly 100 and ensure the volume of the compressor cavity 140, the middle partition 120 is roughly set in an "L" shape, that is, the middle partition 120 includes a first side plate 121 and a second side plate 122, and the first side plate 121 and the second side plate 122 are set at an angle. The first side plate 121 extends in the front-to-back direction YY, and is mainly used to separate the wind wheel cavity 130 and the compressor cavity 140 in the left-right direction. One end of the first side plate 121 extending in the front-to-back direction YY is connected to the front panel 1112, and the other end is connected to the second side plate 122. The second side plate 122 generally extends in the left-right direction XX and is connected to the side panel 1113. The middle partition 120 can be made of sheet metal, and the first side plate 121 and the second side plate 122 are formed by stamping or hot pressing, so that the structural strength of the middle partition 120 is stable and the integrity is good.

[0046] The electric control panel assembly 300 includes a main control panel 310, a filter panel 320, and a drive panel 330, and the outdoor unit 1 also includes a wiring terminal 400 electrically connected to the electric control panel assembly 300. The filter panel 320 and the drive panel 330 are electrically connected to the main control panel 310. The wiring terminal 400 provides a safe and reliable connection point, which facilitates the electrical connection between the filter panel 320, the drive panel 330 and the main control panel 310, and also facilitates the electrical connection between them and external devices. Among them, the filter panel 320, the drive panel 330 and the wiring terminal 400 are installed on the mounting frame 200, and the drive panel 330 is installed on the middle partition 120.

[0047] It should be noted that the main control board 310 is the core component of the electric control board assembly 300, and is mainly responsible for monitoring, controlling and managing the entire electric control system. For example, the main control board 310 can monitor various parameters in the system, such as temperature, humidity, pressure, speed, etc., through external sensors, detectors and other devices to obtain real-time data. Based on the monitored data, the main control board 310 will control and adjust various components of the system, such as starting or stopping the motor, adjusting the valve opening, controlling the temperature, etc., to achieve automatic operation and stability control of the system.

[0048] The filter board 320 is mainly used to ensure the stability and reliability of the electric control system. For example, the filter board 320 can filter the power signal in the electric control system through the filter circuit to remove high-frequency noise and interference to ensure the stability and purity of the power supply signal. It can also effectively suppress the impact of electromagnetic interference and power fluctuations on the electric control system, provide a stable power environment, and reduce interference to other electronic components.

[0049] The drive board 330 receives the control signal from the main control board 310 and converts it into a drive signal that can be understood and executed by the external device to achieve normal operation and precise control of the air conditioning system. For example, the drive board 330 can accurately control the current required by the motor according to the requirements of the control signal. By controlling the current, operations such as starting, running and stopping the motor can be achieved. The drive board 330 can also adjust the voltage to ensure that the motor obtains a suitable voltage supply under different working conditions. The drive board 330 can also control the speed of the motor as needed to adapt to different working modes and requirements.

[0050] When the main control board 310 and the filter board 320 are too close, the electromagnetic fields they generate may interfere with each other, thereby affecting the normal operation of each other. This interference may cause signal distortion, data errors or system performance degradation. In addition, the main control board 310 and the filter board 320 will generate a certain amount of heat when working. If they are too close, thermal coupling problems may occur, that is, the heat of one board is transferred to another board, resulting in an increase in the overall temperature. High temperature may have an adverse effect on the working stability and life of electronic components. Therefore, in order to avoid the above problems, the prior art generally provides an electric control box, and the installation positions of the main control board 310 and the filter board 320 are planned in the electric control box, so as to maintain the installation distance between them, but this installation form is troublesome to assemble, and the overall volume of the electric control box is large, and it is necessary to occupy most of the space inside the outdoor unit 1, and the cost is relatively high. In this application, the main control board 310 and the filter board 320 are installed on the mounting frame 200, and the mounting frame 200 is designed so that the installation of the main control board 310 and the filter board 320 meets the distance requirement, and the structure of the entire outdoor unit 1 is compact. For specific implementation forms, please continue reading the following content.

[0051] Specifically, see Figure 3 , the mounting frame 200 is located in the compressor cavity 140 and is connected to the middle partition 120. Among them, the compressor is located at a position relatively to the lower end of the compressor cavity 140, the mounting frame 200 is located at the upper part of the compressor cavity 140, and the mounting frame 200 is located above the compressor. In this way, the space above the compressor is effectively utilized, and the space is reasonably utilized, making the structure more compact. In some other connection methods, the mounting frame 200 can also be connected to the upper shell 111, for example, one end of the mounting frame 200 is connected to the front panel 1112, and the other end is connected to the side panel 1113, but the present application is not limited to this.

[0052] Please refer to Figure 4 and Figure 5 , in order to maintain a safe distance between the main control board 310 and the filter board 320 while meeting the needs of simplifying the installation work and reducing the assembly space. The present application installs the main control board 310 and the filter board 320 through the mounting frame 200, thereby omitting the electrical control box as in the conventional installation scheme. In this way, the number of parts is relatively reduced, the structure of the outdoor unit 1 is simplified, and because there is no need to specially design an electrical control box, the cost can be reduced. On this basis, in order to ensure that there is a sufficient distance between the main control board 310 and the filter board 320, a boss 223 is formed on the mounting frame 200. The main control board 310 and the filter board 320 are installed on the mounting frame 200 in a back-to-back arrangement, one of the main control board 310 and the filter board 320 is connected to the boss 223, and the other is connected to the side of the mounting portion 220 away from the boss 223. Figure 4 and Figure 5As shown in the example, the main control board 310 is installed on the boss 223, and the filter board 320 is installed on the side of the mounting frame 200 facing away from the boss 223. It can be understood that the height of the boss 223 meets the basic size requirements of the main control board 310 and the filter board 320 to avoid electromagnetic interference.

[0053] By setting the boss 223, the present application can ensure the installation distance between the main control board 310 and the filter board 320, effectively avoiding the electromagnetic fields between them from interfering with each other, thereby affecting their normal operation. In the case where the main control board 310 and the filter board 320 are installed back to back through the mounting frame 200, the space occupied by the overall structure of the three will be smaller, so that in the structure of the outdoor unit 1, other structures in the outdoor unit 1 are easier to arrange and assemble, which can also improve the assembly efficiency.

[0054] In some connection methods, the main control board 310 and the filter board 320 can be fixed to the mounting portion 220 by a snap fastener, that is, one end of the snap fastener is snap-connected to the main control board 310 or the filter board 320, and the other end is snap-connected to the mounting portion 220. The main control board 310 and the filter board 320 can also be fixed to the mounting portion 220 by fasteners such as screws or bolts. The present application does not specifically limit the connection method between the main control board 310 and the filter board 320 and the mounting portion 220.

[0055] See also Figure 3 and Figure 4 In order to facilitate the installation of the terminal block 400 on the mounting frame 200, the mounting frame 200 is further provided with an inner recess 224, wherein the inner recess 224 is recessed toward the inside of the compressor chamber 140 and is spaced apart from the boss 223, and the terminal block 400 is installed on the inner recess 224. The inner recess 224 and the boss 223 can be spaced apart in the up-down direction ZZ, that is, the inner recess 224 is located above the boss 223, or the inner recess 224 is located below the boss 223. Of course, the inner recess 224 and the boss 223 can also be spaced apart in the front-to-back direction YY or the left-to-right direction XX, that is, the inner recess 224 and the boss 223 are spaced apart side by side. In this way, the main control board 310, the filter board 320 and the terminal block 400 can be installed on the mounting frame 200 at the same time, and mutual interference can be avoided. In addition, the embodiment of the present application arranges the connecting terminal 400 in the inner recess 224, which can effectively utilize the internal space of the compressor cavity 140, and can also reduce the collision between the connecting terminal 400 and other objects, thereby preventing the connecting terminal 400 from being damaged or broken.

[0056] It should be noted that the mounting frame 200 can be a plate-like structure and can be made of different materials. For example, the mounting frame 200 can be made of metal materials such as aluminum alloy, iron, stainless steel, etc., and a boss 223 and a recess 224 are formed on the mounting frame 200 by hot pressing, stamping or die-casting. In addition, the mounting frame 200 can also be made of plastic material. For example, plastic materials such as polycarbonate (PC), polypropylene (PP), polystyrene (PS), polyamide (nylon) or polystyrene (PS) can be used to form a boss 223 and a recess 224 on the mounting frame 200 by integral injection molding. The processing method provided by the present application is simple and has good integrity. At the same time, the overall strength is high, which can ensure that the mounting frame 200 can stably install and fix the main control board 310, the filter board 320 and the terminal 400. Here, the present application does not make specific restrictions on the material and processing form of the mounting frame 200.

[0057] To facilitate the transportation of outdoor unit 1, please refer to Figure 6 and Figure 7 , a handle 500 is also connected to the wall of the upper shell 111, and the handle 500 has a handle portion 510. The handle portion 510 of the embodiment of the present application can provide a gripping point, so that the user can carry the outdoor unit 1 through the handle portion 510. Among them, the handle portion 510 is provided on at least one side of the upper shell 111, that is, the upper shell 111 can be provided with the handle portion 510 on one side or both sides in the left and right direction XX direction, that is, the handle portion 510 is provided on the side panels 1113. It can be understood that in order to improve the air intake efficiency of the outdoor unit 1, in some embodiments, the side panels 1113 close to the wind wheel cavity 130 are replaced with grilles, so the handle portion 510 can be set on the side panels 1113 close to the compressor cavity 140. It is further explained that the handle portion 510 is arranged corresponding to the inner recess 224 and is recessed toward the inner recess 224. In this way, the space corresponding to the position of the inner recess 224 in the compressor chamber 140 can be effectively utilized without forming an additional boss structure on the surface of the outdoor unit 1 to form the handle portion 510. This makes the outdoor unit 1 more compact and smaller in overall size.

[0058] In order to further rationally utilize the internal space of the outdoor unit 1, please refer to Figure 4 and Figure 5 The mounting frame 200 includes a mounting portion 220 and a connecting portion 210 connected to the mounting portion 220. The connecting portion 210 is connected to the middle partition plate 120, so as to fix the mounting frame 200 in the compressor chamber 140. The mounting portion 220 includes a first mounting plate 221 and a second mounting plate 222 connected to each other, and the connecting portion 210 is connected to the first mounting plate 221 or the second mounting plate 222. The first mounting plate 221 and the second mounting plate 222 are arranged at an angle. Figure 4As exemplarily shown in FIG. 5 , the connecting portion 210 is connected to the first mounting plate 221 , the first mounting plate 221 is formed with a boss 223 , and the second mounting plate 222 is arranged facing the buckle portion 510 and is formed with an inner recess 224 .

[0059] The angle between the first mounting plate 221 and the second mounting plate 222 can be approximately 90°. It can be understood that the outdoor unit 1 generally has a rectangular outer profile, and the first mounting plate 221 and the second mounting plate 222 are arranged at an angle of approximately 90°, so that the corner space inside the outdoor unit 1 can be used to install the mounting frame 200, without increasing the overall volume of the outdoor unit 1, so as to avoid the boss 223 and the inner recess 224 in the front-to-back direction YY or the left-to-right direction XX of the mounting frame 200.

[0060] Please also refer to 5 and Figure 8 , the first mounting plate 221 extends in the front-to-back direction YY and is spaced apart from the second side plate 122.
