[0038] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] The inventors found that in the structural design of HVAC equipment, the functional components are installed naked on the electric control panel. During the installation and maintenance process, the functional components are easily contacted with other structures to cause collisions. During use, other components inside the HVAC equipment are easily damaged due to improper installation or expansion and squeezing of the functional components. Among them, by setting a protective cover around the functional components, although the functional components can be protected, the protective cover is bulky due to the indiscriminate covering scheme for the functional components, which is not convenient for the maintenance of the functional components and the heat dissipation of the functional components.

[0040] The inventors also discovered that among the multiple functional devices installed on the electrical control panel, some of them are relatively sensitive and easily damaged by bumps, and functional devices that are close to other devices of the HVAC equipment are prone to bumps. Based on the above content, in an embodiment of the present application, protective parts are provided to protect some of the functional devices installed on the electrical control panel that are relatively sensitive and adjacent to other devices of the HVAC equipment, thereby improving the use stability of the HVAC equipment and facilitating maintenance.

[0041] like Figure 1 and Figure 2 FIG. 1 is a schematic diagram of the structure of an electric control assembly 10 according to an embodiment of the present application. The electric control assembly 10 is used for HVAC equipment. The electric control assembly 10 includes a main mounting plate 100 , an electric control board 200 , a plurality of functional components 300 and a protective member 400 .

[0042] The main mounting plate 100 is used to be detachably mounted on the housing of the HVAC equipment. During installation and maintenance, the main mounting plate 100 and the structure mounted on the main mounting plate 100 can be installed on the housing of the HVAC equipment or removed from the housing of the HVAC equipment.

[0043] The electric control board 200 is mounted on the main mounting board 100, wherein, for the convenience of installation and maintenance, a plurality of functional devices 300 are mounted on the same surface of the electric control board 200, specifically, the electric control board 200 has two surfaces arranged opposite to each other along its thickness direction, one of which is a device mounting surface 210, and a plurality of functional devices 300 are mounted on the device mounting surface 210 of the electric control board 200. The functional devices 300 include inductors, relays, reactors, capacitors, line interfaces, display light boards, etc.

[0044] The device mounting surface 210 includes a first mounting area 211, and the functional device 300 includes a protected device 310 mounted in the first mounting area 211. The protected device 310 includes at least one device that needs to be protected, such as a device that is more sensitive and easily damaged by bumps and is closer to other devices of the HVAC equipment. For example, the protected device 310 may include at least part of an inductor, a relay, a reactor, a capacitor, a line interface, and a display light board. The device mounting surface 210 also includes a second mounting area. The other areas of the device mounting surface 210 except the first mounting area 211 form the second mounting area. The devices of the functional device 300 except the protected device 310 are mounted in the second mounting area. Among them, the number of the first mounting area 211 is at least one. When the number of the first mounting area 211 is one, part of the edge area of ​​the device mounting surface 210 or the central area of ​​the device mounting surface 210 forms the first mounting area 211; when the number of the first mounting area 211 is multiple, each first mounting area 211 is provided with at least one protected device 310, and multiple first mounting areas 211 are arranged at intervals, wherein a part of the first mounting area 211 is located at the edge area of ​​the device mounting surface 210, and another part of the first mounting area 211 is located at the central area of ​​the device mounting surface 210. The above is only an exemplary introduction. In the embodiment of the present application, the position of the protected device 310 on the device mounting surface 210 is not limited, and can be selected according to actual application requirements.

[0045] The protective member 400 is disposed corresponding to the first installation area 211 to provide protection for the protected device 310. When there are multiple first installation areas 211, there are also multiple protective members 400 and they are disposed one-to-one corresponding to the multiple first installation areas 211, so that the protective members 400 provide protection for the corresponding protected devices 310. Specifically, Figure 1 As shown, the protective member 400 is spaced apart from the protected device 310, and the protective member 400 is fixed relative to the protected device 310, wherein the protective member 400 includes a protective body 410, as shown in FIG. Figure 3As shown, in the direction perpendicular to the device mounting surface 210, the positive projection of the protective body 410 at least partially covers the positive projection of the protected device 310, and the protective member 400 has a certain structural strength. When the protective member 400 is impacted by an external force, the protective member 400 can withstand the impact of the external force, or the protective member 400 can be slightly deformed to buffer the impact of the external force, thereby protecting the protected device 310 from damage. In this way, during the installation or transportation process, when the electric control component 10 is skewed or other abnormal conditions occur, the protective member 400 contacts the external structure, and after the electric control component 10 is installed in the HVAC equipment, when other components of the HVAC equipment are not installed in place or expand, the protective member 400 contacts other components of the HVAC equipment, thereby preventing the protected device 310 from colliding with other structures by the protective body 410 being located outside the protected device 310, thereby providing effective protection for the protected device 310.

[0046] The protective member 400 is arranged at a distance from the protected device 310, and the coverage area of ​​the protective body 410 is set based on the installation position of the protected device 310. The protective body 410 can provide targeted protection for the protected device 310, and other functional devices 300 installed on the electric control board 200 are exposed, which is beneficial to the heat dissipation of the functional devices 300 installed on the electric control board 200, thereby effectively improving the working stability of the electric control component 10 and facilitating installation and maintenance. In addition, the protective body 410 provides targeted protection for the protected device 310, so that the protective member 400 occupies a small space, which is convenient for designing the installation position of the functional device 300 installed on the electric control board 200, is not easily restricted by the volume of the functional device 300, and is more flexible to install. The protective member 400 is also simpler in structure and lighter in weight, which is beneficial to cost saving.

[0047] The position of the protective member 400 relative to the protected device 310 is fixed. Optionally, the protective member 400 can be installed on the housing of the HVAC equipment to fix the position of the protective member 400 relative to the protected device 310; or, the protective member 400 is installed on the main mounting plate 100 to fix the position of the protective member 400 relative to the protected device 310. Preferably, the protective member 400 is installed on the main mounting plate 100 so that the protective member 400 moves with the main mounting plate 100 and the structure installed on the main mounting plate 100, which is convenient for installation and maintenance.

[0048] like Figure 2As shown, the protective member 400 includes a protective side plate 420, which is detachably mounted on the main mounting plate 100, so as to facilitate the design of the structure of the protective side plate 420 and the protective body 410, so that the protective side plate 420 can be stably mounted on the main mounting plate 100, and the protective body 410 has better anti-impact stability, so as to more fully play the respective roles of the protective side plate 420 and the protective body 410. Among them, the protective side plate 420 and the protective body 410 are integrally arranged, which helps to improve the structural strength of the connection between the protective side plate 420 and the protective body 410, so that the protective body 410 is not easy to move relative to the protected device 310.

[0049] Combination Figure 1 and Figure 2 The main mounting plate 100 includes a first plate body 110 and a second plate body 120 connected at an angle, the electric control board 200 is mounted on the first plate body 110, and the second plate body 120 is located on one side of the electric control board 200 in a direction parallel to the device mounting surface 210, and the protective side plate 420 is detachably mounted on the second plate body 120. By designing the position where the protective side plate 420 is installed on the second plate body 120, the position of the protective body 410 relative to the device mounting surface 210 in a direction perpendicular to the device mounting surface 210 can be adjusted, so that the space between the protective body 410 and the device mounting surface 210 is of appropriate size for installing the protected device 310.

[0050] It can be understood that the protective member 400 is arranged corresponding to the protected device 310, and the protective member 400 is smaller in size than the electrical control board 200. If the extended length of the protective side panel 420 is set to be larger in order to meet the spacing requirement between the protective body 410 and the device mounting surface 210, the force arm of the protective side panel 420 installed on the main mounting plate 100 is longer, resulting in the protective side panel 420 being easily deformed when subjected to impact force, thereby increasing the risk of contact between the protective body 410 and the protected device 310. In an embodiment of the present application, the main mounting plate 100 is provided to include a first plate body 110 and a second plate body 120 at an angle, and the protective member 400 is provided to include a protective body 410 and a mounting side panel. The main mounting plate 100 and the protective member 400 cooperate with each other, which is convenient for meeting the installation space requirement of the protected device 310 and the supporting strength requirement of the protective member 400.

[0051] like Figure 4As shown, the protective side plate 420 has a first mounting surface 4201 perpendicular to the device mounting surface 210, and the first mounting surface 4201 is in contact with the surface of the second plate body 120, thereby improving the installation stability of the protective layer plate installed on the second plate body 120. In addition, the first mounting surface 4201 is perpendicular to the device mounting surface 210, which is convenient for utilizing the space gap between the protective body 410 and the device mounting surface 210 for installing the protected device 310, and can increase the size of the first mounting surface 4201 in the plane where the first mounting surface 4201 is located, thereby increasing the contact area between the protective side plate 420 and the second plate body 120, and further increasing the installation stability of the protective side plate 420 installed on the second plate body 120.

[0052] Optionally, the surface where the second plate body 120 contacts the protective side plate 420 is the second mounting surface 121, and the first mounting surface 4201 and the second mounting surface 121 are both flat and fit each other. Further, the protective side plate 420 is in the shape of a flat plate or a nearly flat plate, so that the protective side plate 420 has a regular appearance, and prevents the mounting side plate from occupying the space between the protective body 410 and the device mounting surface 210 and affecting the installation of the protected device 310.

[0053] The protective side panel 420 extends from the protective body 410 toward the side where the electric control board 200 is located, and is fixedly installed on the second plate body 120, so as to prevent the protective side panel 420 from protruding from the side of the protective body 410 away from the device mounting surface 210 and affecting the installation of other devices of the HVAC equipment. It is also convenient to set the protective side panel 420 and the protective body 410 as one piece. For example, a bending processing method is adopted to bend a substrate into the protective side panel 420 and the protective body 410, or the protective side panel 420 and the protective body 410 are injection molded as one piece, which is convenient for processing.

[0054] Optionally, the protective side plate 420 and the main mounting plate 100 are respectively provided with a plurality of threaded holes, and the protective side plate 420 can be fixedly mounted on the main body by screw locking. Alternatively, in some other embodiments, the protective side plate 420 can also be fixedly mounted on the main body by welding.

[0055] Optionally, during the assembly process, the protective side plate 420 may be pre-installed on the main mounting plate 100, and after the protective member 400 is initially positioned, the protective side plate 420 may be fixedly installed on the main mounting plate 100. Figure 1 and Figure 2As shown, the protective member 400 has a first matching portion 510 connected to the protective side plate 420, and the second plate body 120 has a second matching portion 520. The first matching portion 510 and the second matching portion 520 form a group of matching units 500. The number of matching units 500 is multiple groups. The first matching portion 510 and the second matching portion 520 of each group of matching units 500 cooperate to position the protective member 400 relative to the main installation plate 100, preliminarily position the protective member 400, adjust the position of the protective member 400 relative to the protected device 310, and then fix the position of the protective member 400 relative to the main installation plate 100, so as to improve the installation efficiency and installation stability of the protective member 400 installed on the main installation plate 100.

[0056] Optionally, one of the first matching portion 510 and the second matching portion 520 has a hook 511 and the other has a slot 521 , and the hook 511 is engaged with the slot 521 to preliminarily locate the protective element 400 relative to the main mounting plate 100 .

[0057] The hooks 511 of at least two sets of matching units 500 are bent in directions forming an angle with each other, for example, Figure 4 As shown, the hooks 511 of the two groups of mating units 500 are bent in directions that form an angle with each other; in some other embodiments, the number of mating units 500 may also be four, five or six groups or other groups, and the hooks 511 of one group of mating units 500 are set at an angle with the hooks 511 of the remaining mating units 500, or the hooks 511 of two or more groups of mating units 500 are set at an angle with the hooks 511 of the remaining mating units 500.

[0058] The hooks 511 of at least two sets of matching units 500 are bent in the same direction, for example, Figure 5 As shown, the hooks 511 of the two groups of matching units 500 are bent in the same direction; in some other embodiments, the number of matching units 500 can also be three, five or six groups, and the hooks 511 of all matching units 500 are bent in the same direction.

[0059] In some other embodiments, one of the first matching portion 510 and the second matching portion 520 may be a slider (not shown in the figure) and the other may be a slide groove (not shown in the figure), the slider is arranged in the slide groove, and the slider and the slide groove are interference fit to preliminarily locate the position of the protective member 400 relative to the main installation plate 100. The above is only an exemplary introduction, and the structure of the first matching portion 510 and the second matching portion 520 is not limited in this application. Any combination structure of the first matching portion 510 and the second matching portion 520 that can be used to preliminarily locate the position of the protective member 400 relative to the main installation plate 100 is applicable to this application, and can be selected according to actual needs.

[0060] When the first matching portion 510 of the protective member 400 is a hook 511, the second plate body 120 of the main mounting plate 100 is correspondingly provided with a bayonet 521, wherein the middle area of ​​the second mounting surface 121 of the second plate body 120 is provided with a bayonet 521, or the edge of the second mounting surface 121 is provided with a bayonet 521, and the hook 511 is engaged with the corresponding bayonet 521. In some other embodiments, the hook 511 may also be directly provided at the edge of the second mounting surface 121, for example, Figure 1 As shown, when the protective side plate 420 is provided with two hooks 511, and the two hooks 511 are bent in directions that are angled with each other, one of the hooks 511 is engaged in a slot 521 opened in the middle area of ​​the second mounting surface 121, and the other hook 511 is clamped on the edge of the second mounting surface 121 of the second plate body 120, so as to achieve the initial positioning of the protective member 400.

[0061] like Figure 4 and Figure 5 As shown, the protective side plate 420 includes a first mounting section 421, a second mounting section 422 and a transition mounting section 423 connected between the first mounting section 421 and the second mounting section 422. The first mounting section 421, the second mounting section 422 and the transition mounting section 423 are all integrally arranged on the protective body 410. The surfaces of the first mounting section 421, the second mounting section 422 and the transition mounting section 423 facing the second plate body 120 together form a first mounting surface 4201. In the direction perpendicular to the device mounting surface 210, the widths of the first mounting section 421 and the second mounting section 422 are both greater than the width of the transition mounting section 423. On the one hand, the strength of the connection structure between the first mounting section 421 and the second mounting section 422 is increased by the transition mounting section 423. On the other hand, the transition mounting section 423 is prevented from being too large in size and increasing the overall weight of the protective member 400. Among them, the first mounting section 421 and the second mounting section 422 are respectively provided with threaded holes. When fixing the position of the protective member 400 relative to the main mounting plate 100, screws are set in the threaded holes of the first mounting section 421 and the second mounting section 422 to fix the protective member 400 to the second plate body 120. In addition, when selecting the installation position of the hook 511, it is also preferred to install the hook 511 on the first mounting section 421 and the second mounting section 422 so as to flexibly set the bending direction of the hook 511.

[0062] It can be understood that the protective body 410 is set corresponding to the protected device 310. In the embodiment of the present application, the protective body 410 is only installed on the main installation board 100 through the protective side plate 420, and the other positions of the protective body 410 are suspended. In the process of installing the protective member 400 on the main installation board 100, the protective member 400 needs to be positioned to prevent the protective member 400 from being misplaced during the installation process. In addition, since the protective body 410 has a larger coverage area perpendicular to the device installation surface 210, and the thickness of the protective body 410 in the direction perpendicular to the device installation surface 210 is relatively thin, it is not convenient to act on the protective body 410 to move the protective member 400, and it is easy to cause unstable positioning. Based on this, the protective member 400 is provided to include at least one auxiliary flange 430, the auxiliary flange 430 is protruded from the surface of the protective body 410 facing the electric control board 200, and the auxiliary flange 430 is integrally provided with the protective body 410. In the process of installing the protective member 400 on the main mounting plate 100, tooling can be used to act on the auxiliary flange 430 to move or fix the position of the protective member 400, which is convenient to operate.

[0063] In addition, the presence of the auxiliary flange 430 can also increase the structural strength of the protective body 410, effectively improve the impact resistance of the protective body 410, and make the protective body 410 less likely to deform. When the number of the auxiliary flanges 430 is multiple, the multiple auxiliary flanges 430 can be divided into two groups and arranged relatively. Specifically, the protective body 410 has a first edge and a second edge arranged relatively along a first direction, and a third edge and a fourth edge arranged relatively along a second direction. The first direction is perpendicular to the second direction and both are parallel to the device mounting surface 210, wherein a part of the auxiliary flange 430 is connected to the first edge, another part of the auxiliary flange 430 is connected to the second edge, and the protective side plate 420 is connected to the third edge. Optionally, when the electric control component 10 is applied to HVAC equipment, the first direction is a vertical direction and the second direction is a horizontal direction.

[0064] The auxiliary flange 430 is spaced apart from the protective side plate 420 , for example, the auxiliary flange 430 is spaced apart from at least one of the first mounting section 421 and the second mounting section 422 of the protective side plate 420 , so as to facilitate processing of the auxiliary flange 430 and the protective side plate 420 on the protective body 410 .

[0065] Optionally, the protective body 410, the first mounting section 421, the second mounting section 422, the transition mounting section 423, the hook 511 and the auxiliary flange 430 of the protective part 400 can all be made of the same material. For example, they can be made of a plastic material with good supporting strength, heat resistance, corrosion resistance, and insulation. Alternatively, a metal protective body can be used, and the protective part 400 can be made of an insulating material coated on the surface of the metal protective body, so that the protective part 400 still has good stability in an environment with frequent temperature changes.

[0066] Taking into account that the protective member 400 has a certain weight, the protective body 410 has at least one weight-reducing opening 411. The present application does not limit the design method of the weight-reducing opening 411, and the specific design method can be selected according to actual needs. However, it should be noted that after the protective member 400 is installed on the HVAC equipment, the size of the weight-reducing opening 411 must meet the requirement that when the external structural parts contact the protective body 410, they will not pass through the weight-reducing opening 411 and contact the functional components 300 on the electrical control board 200.

[0067] Some of the protected devices 310 corresponding to the protective member 400 need to be connected to other devices through connecting wires, or functional devices other than the protected devices 310 on the electrical control board 200 also need to be connected to other devices through connecting wires. The protective body 410 is provided with at least one wire hole 412, and the above-mentioned connecting wire can be routed through the wire hole 412 of the protective body 410. The protective member 400 provides support for the connecting wire, thereby improving the orderliness of the routing of the connecting wire and preventing the connecting wire from being bent at a large angle during routing, thereby preventing the connection from being unstable.

The radiator 600 includes a heat dissipation body 610 and a plurality of heat dissipation fins 620 arranged on the same side of the heat dissipation body 610. The heat dissipation fins 620 penetrate the heat dissipation opening 111. The heat dissipation body 610 is located on the side of the electric control board 200 away from the device mounting surface 210, and the heat dissipation body 610 and the electric control board 200 are stacked and installed on the main mounting board 100 in a direction perpendicular to the device mounting surface 210. The functional device 300 and the radiator 600 are arranged on two opposite sides of the electric control board 200, so as to facilitate the heat dissipation of the functional device 300.

[0069] Optionally, the surface of the electric control board 200 away from the device mounting surface 210 is in contact with or spaced apart from the heat dissipation body 610. When the surface of the electric control board 200 away from the device mounting surface 210 is spaced apart from the heat dissipation body 610, a heat conductive layer (not shown in the figure) may be further provided between the electric control board 200 and the heat dissipation body 610. The surface of the heat conductive layer is respectively in contact with the electric control board 200 and the heat dissipation body 610 to improve the heat dissipation efficiency.

[0070] The embodiment of the present application further provides a HVAC device, which includes a housing and the electric control component 10 as described above, wherein a main mounting plate 100 of the electric control component 10 is mounted on the housing.

[0071] The housing includes an outer shell and a middle partition 22, and the middle partition 22 is arranged in the inner space of the outer shell.

The HVAC equipment also includes a fan (not shown in the figure) and a pipeline assembly 23, the fan is arranged in the wind cavity 22b, and the pipeline assembly 23 is arranged in the installation cavity 22c. Figure 7 As shown, the middle partition 22 has a partition opening 22a connecting the air cavity 22b and the installation cavity 22c, the main installation plate 100 is arranged at the partition opening 22a, the electronic control board 200, the functional device 300 and the protective member 400 are all accommodated in the installation cavity 22c, wherein, when the heat sink 620 of the radiator 600 passes through the heat dissipation opening 111, the heat sink 620 extends into the air cavity 22b, and the airflow generated by the operation of the fan can take away the heat on the radiator 600 in time, and the heat dissipation efficiency is high.

[0072] In addition to the fan and the pipe assembly 23, the HVAC equipment may also include a variety of devices such as a heat exchanger, an expansion tank, a water tank, a compressor, and a subcooler arranged in the installation cavity 22c. The pipe assembly 23 includes a plurality of connecting pipes and valve bodies connecting these devices. The refrigerant is transmitted and heat exchanged in these devices through the connecting pipes and valve bodies. Among them, the connecting pipes and valve bodies are easily expanded due to the heat of the refrigerant. By providing the protective member 400, it is possible to effectively prevent the connecting pipes and valve bodies from squeezing the functional device 300 arranged on the electric control board 200, thereby improving the use stability of the HVAC equipment.
