[0044] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood, and so that the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0045] It is to be understood that the terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises", "comprising", "includes", "including" and "has" are inclusive and therefore specify the presence of stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order in which they are described, unless specifically identified as an order dependent step. It is also to be understood that additional or alternative steps can be employed.

[0046] Although the terms first, second, third, etc. can be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as "first", "second", and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.

[0047] Spatially relative terms, such as "inner", "outer", "beneath", "below", "lower", "above", "upper", and the like, can be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures.

[0048] The electric control board of the outdoor unit of an air conditioner is provided with a plurality of electronic components, including many heat-generating components with large heat generation, such as frequency conversion modules, etc. If these heat-generating components cannot be cooled, the failure rate of the heat-generating components themselves and the surrounding electronic components will greatly increase.

[0049] The commonly used heat dissipation technologies include natural heat dissipation and refrigerant heat dissipation. The natural heat dissipation has the disadvantage of poor effect, and the high temperature rise of the heating device leads to the device damage and short service life. The refrigerant heat dissipation is usually performed through the refrigerant pipe, and the effect of the refrigerant heat dissipation is better than that of the natural heat dissipation, which can effectively reduce the temperature of the heating device and prolong the service life of the heating device. However, the existing refrigerant pipe is inconvenient to install, and is prone to move during the installation process, thereby affecting the heat dissipation effect and the assembly efficiency.

[0050] Therefore, the utility model provides an electric control heat dissipation assembly 70, which aims to solve the problem of inconvenient installation of the existing refrigerant pipe 73.

[0051] As Figures 1-7 Indicated, electric control heat dissipation assembly 70 is used for outdoor unit 1, and it specifically includes heat dissipation piece 71, apron 72 and refrigerant pipe 73. Wherein, heat dissipation piece 71 has installation side 711 and heat conduction side 712 opposite along first direction a, and heat conduction side 712 is used to heat conduction with electric control element. Apron 72 is detachably arranged at installation side 711, and apron 72 is equipped with first accommodating groove 721 and at least two clamping pieces 722. Refrigerant pipe 73, refrigerant pipe 73 is installed in first accommodating groove 721 through clamping piece 722, and is clamped between heat dissipation piece 71 and apron 72, to be used to heat exchange with heat dissipation piece 71.

[0052] Specifically, by setting apron 72, refrigerant pipe 73 can be kept in contact with heat dissipation piece 71 to prevent refrigerant pipe 73 from separating from heat dissipation piece 71 and affecting the heat dissipation effect of heat dissipation piece 71. At the same time, clamping piece 722 is arranged on apron 72 to enable refrigerant pipe 73 to be pre-installed on apron 72 and clamped between heat dissipation piece 71 and apron 72 with the installation of apron 72, which helps to improve the convenience of refrigerant pipe 73 installation and the assembly efficiency of electric control heat dissipation assembly 70.

[0053] It should be understood that the outdoor unit 1 provided by the utility model can be an outdoor unit 1 of an air conditioner or an outdoor unit 1 of other heating and ventilation equipment. The outdoor unit 1 has a cabinet 10, which forms an accommodating cavity inside. The interior of the cabinet 10 is provided with a partition plate (not shown in the figure), which divides the accommodating cavity into a first cavity 1001 and a second cavity (not shown in the figure). The interior of the first cavity 1001 is provided with a compressor, a four-way valve assembly, and an electric control device 30. The second cavity is provided with a fan and a heat exchanger. The electric control device 30 is arranged on the partition plate, and the electric control heat dissipation assembly 70 is arranged on the electric control device 30.

[0054] Still as Figure 1 AndFigure 2 As shown, the electric control device 30 comprises an electric control support 31 and a main plate 32, wherein the electric control support 31 is mounted on the partition plate, the main plate 32 is mounted on the electric control support 31, and the electric control heat dissipation assembly 70 is mounted on the main plate 32 and abuts against the electric control elements of the main plate 32 to be able to conduct the heat generated by the electric control elements out. In the embodiment, the mounting of the electric control support 31 on the partition plate and the mounting of the main plate 32 on the electric control support 31 are both achieved by screwing and fixedly connected. Meanwhile, the main plate 32 is provided with a support frame 74 surrounding the periphery of the electric control elements to protect the electric control elements, and the electric control heat dissipation assembly 70 is mounted on the main plate 32 through the support frame 74. Optionally, the support frame 74 and the main plate 32 are fixed together by screwing or bonding.

[0055] The electric control heat dissipation assembly 70 comprises a heat dissipation piece 71, a cover plate 72 and a refrigerant pipe 73. The heat dissipation piece 71 is provided with a first mounting hole (not shown in the figure), the support frame 74 is provided with a second mounting hole (not shown in the figure), and a screwing piece is arranged in the first mounting hole and the second mounting hole to fix the heat dissipation piece 71 on the support frame 74. The heat dissipation piece 71 has an installation side 711 and a heat conduction side 712 oppositely arranged along a first direction a, and the heat conduction side 712 is used to be in thermal conduction with the electric control elements. In the embodiment, the first direction a is the length direction of the outdoor unit 1. The cover plate 72 is arranged on the installation side 711, and the refrigerant pipe 73 is arranged between the cover plate 72 and the heat dissipation piece 71 and abuts against the heat conduction side 712.

[0056] It can be understood that the heat conduction form between the heat conduction side 712 and the electric control elements is various, which can be direct contact or indirect contact through a heat conduction medium, such as heat conduction through heat paste, and the present application does not limit this. In addition, the refrigerant pipe 73 has flowing refrigerant, and the electric control heat dissipation assembly 70 absorbs and carries away the heat transferred by the heat dissipation piece 71 through the flow of the refrigerant in the refrigerant pipe 73, so as to achieve the purpose of cooling. In the embodiment, the refrigerant in the refrigerant pipe 73 can be water or cooling liquid.

[0057] In order to facilitate the heat transfer of the electric control elements to the heat dissipation piece 71, in the embodiment, the heat conduction side 712 is formed with a heat conduction protruding rib 715 extending away from the installation side 711, which is used for thermal conduction with the electric control elements. The heat dissipation piece 71 is provided with the heat conduction protruding rib 715, so that the heat dissipation piece 71 can be inserted into the electric control elements, which helps to strengthen the contact between the heat dissipation piece 71 and the electric control elements, so as to directly conduct the heat of the electric control elements to the heat dissipation piece 71 and improve the heat dissipation efficiency of the heat dissipation piece 71. It can be understood that the heat conduction form between the heat conduction protruding rib 715 and the electric control elements is various, which can be direct contact or indirect contact through a heat conduction medium, such as heat conduction through heat paste or other heat conduction medium.

[0058] It should be noted that the number of heat-conducting ribs 715 is not limited, and multiple heat-conducting ribs 715 can be arranged along the extension direction of the heat-conducting side 712, or one heat-conducting rib 715 can be arranged along the extension direction of the heat-conducting side 712.

[0059] It should be noted that the connection form of the cover body and the heat-dissipating piece 71 is various, the cover body can be welded together with the heat-dissipating piece 71, or can be buckled, or can be other forms, the utility model does not make limitation to this, further, for the maintenance and repair of the refrigerant pipe 73 and the electric control heat-dissipating structure, the cover body is detachably connected to the base, specifically, the cover body is provided with a first fixing hole 728, the heat-dissipating piece 71 is provided with a second fixing hole 714 corresponding to the first fixing hole 728, and the electric control heat-dissipating assembly 70 further comprises a fixing bolt, the fixing bolt is arranged in the first fixing hole 728 and the second fixing hole 714, so that the cover body is convenient to assemble and disassemble and firm.

[0060] As shown in FIG. 1, Figures 2-6 As shown in FIG. 1,

[0061] At this time, the refrigerant pipe 73 comprises a straight segment 732 and a U-shaped segment 731, the number of the straight segments 732 is two, and the two straight segments 732 are respectively connected to the two ends of the U-shaped segment 731, the straight segment 732 is matched with the first accommodating groove 721, and at least part of the straight segment 732 can be accommodated in the first accommodating groove 721, meanwhile, the straight segment is in abutment with the clamping piece 722 and is limited in the first accommodating groove 721 by the clamping piece 722, so as to realize the installation of the refrigerant pipe 73 on the cover plate 72. Wherein, the specific structure of the clamping piece 722 is not limited here, as long as it can realize the fixation of the refrigerant pipe 73.

[0062] Further, the heat dissipation member 71 has a first end 7101 and a second end 7102 oppositely arranged between the mounting side 711 and the heat conduction side 712 and along the second direction b, the second direction b is perpendicular to the first direction a, the mounting side 711 is provided with a second accommodating groove 713, the second accommodating groove 713 penetrates the first end 7101 and the second end 7102, and cooperates with the first accommodating groove 721 to form a mounting hole, at the same time, at least part of the refrigerant pipe 73 is accommodated in the mounting hole, and along the second direction b, the at least two clamping members 722 are respectively located on opposite sides of the mounting hole.

[0063] Specifically, by arranging the second accommodating groove 713 to form the mounting hole cooperated with the first accommodating groove 721, and the mounting hole is adapted to the refrigerant pipe 73, the refrigerant pipe 73 can be limited to be fixed between the heat dissipation member 71 and the cover plate 72, and the refrigerant pipe 73 is kept in contact with the heat dissipation member 71. By limiting the clamping members 722 to be respectively located on opposite sides of the mounting hole, it helps to ensure the pre-installation of the refrigerant pipe 73 on the cover plate 72, and the installation of the cover plate 72 and the heat dissipation member 71 can be effectively implemented, avoiding structural conflicts, and effectively ensuring the contact area of the refrigerant pipe 73 and the heat dissipation member 71.

[0064] It should be understood that, as shown in Figures 2-4 the second direction b, the heat dissipation member 71 has the first end 7101 and the second end 7102 oppositely arranged, i.e. the top end and the bottom end, the first end 7101 and the second end 7102 are between the mounting side 711 and the heat conduction side 712. The mounting side 711 is provided with the second accommodating groove 713, the second accommodating groove 713 can penetrate and communicate the first end 7101 and the second end 7102, and when the cover plate 72 is connected with the heat dissipation member 71, the second accommodating groove 713 cooperates with the first accommodating groove 721 to form a mounting hole. At this time, the straight line segment 732 of the refrigerant pipe 73 can be wholly or partially accommodated in the mounting hole, and the cover plate 72 can keep the refrigerant pipe 73 in contact with the heat dissipation member 71. In this way, the refrigerant pipe 73 can be effectively prevented from being separated from the heat dissipation member 71, and the heat dissipation effect of the heat dissipation member 71 can be avoided. At the same time, along the second direction b, the two clamping members 722 of the same group are respectively arranged at opposite ends of one mounting hole, so as to avoid the clamping members 722 affecting the connection of the cover plate 72 and the heat dissipation member 71, and to ensure the contact area of the refrigerant pipe 73 and the second accommodating groove 713.

[0065] It should be pointed out that, in the present embodiment, when the cover plate 72 is installed on the heat dissipation member 71, the heat dissipation member 71 abuts against the cover plate 72, and part of the heat of the heat dissipation member 71 is transferred to the cover plate 72. In order to improve the heat dissipation performance of the electric control heat dissipation structure, the materials of the heat dissipation member 71, the refrigerant pipe 73 and the cover plate 72 are all metal materials. Since metal has high heat conduction performance, using metal material can help to provide the heat dissipation performance of the electric control heat dissipation structure, and preferably, the metal material is copper or aluminum.

[0066] Further, the clamping member 722 includes two elastic pieces arranged on the cover plate 72 and extending along the first direction a, and a limiting portion 72211 is arranged on each elastic piece. The two elastic pieces are arranged on the two sides of the first accommodating groove 721 along the third direction c which is perpendicular to the first direction a, and a clamping channel is formed. The two limiting portions 72211 are both located inside the clamping channel, and the distance between the two limiting portions 72211 is less than the outer diameter of the refrigerant pipe 73.

[0067] Specifically, by arranging the clamping member 722 as an elastic piece, the manufacturing difficulty of the clamping member 722 is reduced due to the simple structure of the elastic piece and the deformation characteristics, and the operation is convenient, which facilitates the installation efficiency of the refrigerant pipe 73. At the same time, by arranging the limiting portion 72211, the limiting effect on the refrigerant pipe 73 is further improved.

[0068] It should be understood that each clamping member 722 includes two elastic pieces, which are referred to as a first elastic piece 7221 and a second elastic piece 7222 for convenience of description. The first elastic piece 7221 and the second elastic piece 7222 are the same in structure and are symmetrically arranged on opposite sides of the first accommodating groove 721 along the third direction c which is the width direction of the outdoor unit 1. In the present embodiment, the first elastic piece 7221 is arranged at one end of the cover plate 72, and the other end of the first elastic piece 7221 is arranged to extend along the first direction a. At this time, the first elastic piece 7221 and the second elastic piece 7222 form a clamping channel due to the spacing arrangement, so that the refrigerant pipe 73 can enter and be clamped. The arrangement of the clamping channel facilitates the difficulty of the refrigerant pipe 73 to separate from the cover plate 72. At the same time, the limiting portion 72211 is arranged on the first elastic piece 7221. The limiting portions 72211 of the two elastic pieces are both located inside the clamping channel, and the distance between the two limiting portions 72211 is less than the outer diameter of the refrigerant pipe 73, which further prevents the refrigerant pipe 73 from separating from the cover plate 72.

[0069] It should be pointed out that the elastic piece structures of the two clamping members 722 in the same group can be the same or different, so as to achieve the clamping and fixing of the refrigerant pipe 73. At the same time, the two clamping members 722 in the same group can also be arranged as different structures, so as to achieve the pre-installation of the refrigerant pipe 73 on the cover plate 72.

[0070] In addition, in the present embodiment, a reinforcing portion 72212 is arranged at the connection between the first elastic piece 7221 and the cover plate 72, which is arranged as a reinforcing rib structure to improve the connection effect between the first elastic piece 7221 and the cover plate 72, thereby improving the structural strength of the clamping member 722.

[0071] It needs to be further understood that the first accommodating groove 721 has an opening larger than the outer diameter of the refrigerant pipe 73. By making the opening of the first accommodating groove 721 larger than the outer diameter of the refrigerant pipe 73, on the one hand, it is convenient to install the refrigerant pipe 73 in the first accommodating groove 721, and at the same time, when the cover plate 72 is connected with the heat dissipation piece 71, since the second accommodating groove 713 is matched with the refrigerant pipe 73, the refrigerant pipe 73 can be adjusted in the first accommodating groove 721 to guarantee the abutting effect of the second accommodating groove 713 and the refrigerant pipe 73; on the other hand, as shown in the figure, the opening is larger than the outer diameter of the refrigerant pipe 73, and a water guide groove can be formed on the mounting hole, so that the condensed water generated on the refrigerant pipe 73 and the heat dissipation piece 71 can flow away from the bottom of the electric control heat dissipation assembly 70 along the water guide groove. Figure 6

[0072] Further, the refrigerant pipe 73 comprises a U-shaped section 731 and a straight section 732 communicated with the U-shaped section 731, and at least part of the straight section 732 is installed in the first accommodating groove 721.

[0073] In the second direction b, one end of the cover plate 72 is provided with a protection part 723, and a limiting piece 724 is arranged on the protection part 723, which is clamped with the U-shaped section 731 of the refrigerant pipe 73.

[0074] Specifically, by arranging the protection part 723, the limiting piece 724 can be provided with an installation base, and then the limiting piece 724 can be clamped with the U-shaped section 731 of the refrigerant pipe 73 to realize the positioning installation of the refrigerant pipe 73 on the cover plate 72. At the same time, the arrangement of the protection part 723 can also avoid the contact or damage of the external structure to the U-shaped section 731, so as to guarantee the service life of the refrigerant pipe 73.

[0075] It can be understood that the protection part 723 is arranged at the top end of the cover plate 72, wherein the limiting piece 724 is arranged on the side surface of the protection part 723 facing the refrigerant pipe 73, which can be clamped with the U-shaped section 731 of the refrigerant pipe 73 to realize the positioning installation of the refrigerant pipe 73 on the cover plate 72, which helps to improve the installation efficiency of the electric control heat dissipation assembly 70, and then guarantees the assembly efficiency of the outdoor unit 1. Optionally, the structure of the limiting piece 724 is the same as or similar to that of the clamping piece 722, which helps to reduce the manufacturing difficulty of the cover plate 72 and guarantees the convenience and accuracy of the installation of the refrigerant pipe 73. Of course, the structure of the limiting piece 724 and the structure of the clamping piece 722 can also be different, as long as they can realize the positioning installation of the U-shaped section 731, which is not limited here.
