[0003] Specifically, because the electrical control box in the related technical solution is fixed to the windbreak, it is necessary to extend the refrigerant circulation pipeline to a certain length to ensure that the refrigerant pipe in the refrigerant circulation pipeline can extend to the windbreak and achieve contact with the heat sink. However, considering the operation of the compressor, the refrigerant circulation pipeline will vibrate when the compressor is running. Combined with the characteristics of the installation position of the above-mentioned electrical control box, the instability caused by vibration of the refrigerant circulation pipeline is increased. Utility Model Content

[0004] The technical problem solved by the present invention is that, because the electrical control box in the related technical solution is fixed to the windbreak plate, it is necessary to extend the refrigerant circulation pipeline to a certain length to ensure that the refrigerant pipe in the refrigerant circulation pipeline can extend to the windbreak plate to achieve contact with the heat sink. However, considering the operation of the compressor, the refrigerant circulation pipeline will vibrate when the compressor is running, and the characteristics of the installation position of the above-mentioned electrical control box increase the instability of the refrigerant circulation pipeline caused by vibration.

[0005] In order to solve the above problems, the utility model provides an outdoor unit, including: a condenser, wherein the installation side of the condenser is provided with a side plate structure for fixing the refrigerant pipe group; an electrical control box, which is arranged on the installation side and connected to the side plate structure; wherein the heat dissipation component of the electrical control box cooperates with the refrigerant pipe group.

[0006] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting the electric control box on the side plate structure, compared with fixing the electric control box to other positions, for example, comparing this technical solution with the implementation method of installing the electric control box on the wind-proof vertical plate, on the one hand, the extended length of the refrigerant pipe group that can be smoothly matched to the heat sink is shortened, and by shortening the extended length, the adverse effects caused by the extended length of the refrigerant pipe group on the heat exchange function of the air conditioner are reduced as much as possible; on the other hand, the assembly method of setting the electric control box on the side plate structure ensures consistency with the assembly environment of the refrigerant pipe group as much as possible, reducing the risk of aggravated vibration due to the inconsistency between the assembly environment of the electric control box and the assembly environment of the refrigerant pipe group. In addition, it can be understood that by shortening the above-mentioned extended length, the waste of resources caused by thermal interaction between the refrigerant pipe group and the surrounding environment is reduced.

[0010] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: for example, in the solution where the heat sink is matched with the elbow structure, since the elbow structure has a curved portion, the elbow structure has a larger heat dissipation surface area compared to the straight refrigerant pipe. By matching the heat sink with the elbow structure, the thermal interaction efficiency between the heat sink and the elbow structure is improved, ensuring the heat dissipation effect of the main control chip in the electronic control box and the electronic control components connected to the main control chip.

[0012] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting the yield structure to cooperate with the second refrigerant elbow, it effectively avoids the collision between the electric control box and the second refrigerant elbow, while realizing the cooperation between the heat sink and the first refrigerant elbow, and ensuring the tight fit between the electric control box and the refrigerant pipe group.

[0013] In an embodiment of the present invention, the side plate structure and the electric control box are coupled by either a snap connection or a screw connection, or a combination of the two.

[0014] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: for example, in order to improve the stability of the electric control box installed on the side plate structure, the electric control box and the side plate structure can be screwed.

Combined with the connection holes provided on the surrounding edge, when the pre-positioning is completed, the difficulty of matching the screw holes and the connection holes provided on the electric control box is reduced, thereby improving the assembly efficiency of installing the electric control box to the side plate structure.

[0017] In one example of the present invention, the electrical control box includes a connecting body and a fixing member that cooperate with each other; the first end of the connecting body is connected to the side plate structure, and the second end is provided with a mounting position for assembling the heat sink; the fixing member cooperates with the connecting body to form an assembly space for encapsulating the heat sink and the refrigerant pipe group.

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] Specifically, the refrigerant pipe group is connected to the compressor of the outdoor unit, and the operation of the compressor realizes the function of transporting the refrigerant in the refrigerant pipe group between the indoor unit and the outdoor unit.

[0041] In the related art, heat dissipation for the main control chip of the electric control box and the multiple electronic control components connected to it is often achieved by installing a heat sink. Specifically, a heat sink is installed on one side of the main control chip, utilizing the thermal interaction between the heat sink and the surrounding environment to dissipate heat from the main control chip and the multiple electronic control components. To ensure this heat dissipation effect, the heat sink is often set to a large size, which further squeezes the internal installation space of the outdoor unit. This further reduction in internal installation space also affects the heat dissipation effect of the heat sink.

[0042] Therefore, in order to address the above-mentioned problems, the relevant technology has been improved. Specifically, by utilizing the above-mentioned combination of the refrigerant tube group and the heat sink, the refrigerant in the refrigerant tube group absorbs the heat on the surface of the heat sink, thereby achieving the effect of dissipating heat from the heat sink. Furthermore, in order to stably fix the electric control box, it is often installed on the windbreak plate of the outdoor unit. The windbreak plate is used to separate the installation chamber of the outdoor unit into a compressor chamber for installing the compressor and a fan chamber for installing the fan. The electric control box is set on one side of the windbreak plate located in the compressor chamber. In order to adapt to the setting position of the electric control box, the length of the refrigerant tube group needs to be extended. However, considering the operation of the compressor, since the compressor will drive the refrigerant tube group to vibrate when it is running, and the large distance between the windbreak plate and the condenser further reduces the difficulty of stably fixing the refrigerant tube group, which also increases the instability of the refrigerant tube group caused by vibration, thereby affecting the efficiency of the air conditioner.

[0043] To solve the above problems, see Figure 1 , which is a structural diagram of an outdoor unit 100 provided by an embodiment of the present utility model. Figure 2-Figure 8 The outdoor unit 100, for example, includes a condenser 10 and an electrical control box 20. The installation side 101 of the condenser 10 is provided with a side plate structure 11 for fixing the refrigerant pipe group 12; the electrical control box 20 is arranged on the installation side 101 and connected to the side plate structure 11; wherein, the heat dissipation component 21 of the electrical control box 20 cooperates with the refrigerant pipe group 12.

[0044] Specifically, by setting the electric control box 20 on the side plate structure 11, compared with fixing the electric control box 20 to other positions, for example, comparing this technical solution with the implementation of installing the electric control box 20 on the windproof vertical plate, on the one hand, the extended length of the refrigerant tube group 12 that can smoothly fit into the heat sink 21 is shortened, and by shortening the extended length, the adverse effects caused by the extended length of the refrigerant tube group 12 on the heat exchange function of the air conditioner are reduced as much as possible; on the other hand, the assembly method of setting the electric control box 20 on the side plate structure 11 ensures consistency with the assembly environment of the refrigerant tube group 12 as much as possible, reducing the risk of increased vibration due to the inconsistency between the assembly environment of the electric control box 20 and the assembly environment of the refrigerant tube group 12. In addition, it can be understood that by shortening the above-mentioned extended length, the waste of resources caused by thermal interaction between the refrigerant tube group 12 and the surrounding environment is reduced.

[0045] Preferably, the refrigerant pipe group 12 is provided with a plurality of elbow structures 124 mounted on the side plate structure 11; the electric control box 20 is provided with a clearance structure 22 for making way for the elbow structures 124. By providing the clearance structure 22, the electric control box 20 and the elbow structures 124 are prevented from being squeezed against each other.

[0046] Combine Figure 4 and Figure 8 Preferably, the heat sink 21 cooperates with at least one liquid outlet branch pipe 121 in the refrigerant pipe assembly 12; or, the heat sink 21 cooperates with at least one of the multiple elbow structures 124. For example, in the scheme where the heat sink 21 cooperates with the elbow structure 124, because the elbow structure 124 has a curved portion, the elbow structure 124 has a larger heat dissipation surface area compared to a straight refrigerant pipe. By cooperating with the heat sink 21 and the elbow structure 124, the thermal interaction efficiency between the heat sink 21 and the elbow structure 124 is improved, ensuring the heat dissipation effect for the main control chip in the electronic control box 20 and the electronic control components connected to the main control chip.

[0047] In contrast, in the solution where the heat sink 21 is matched with the liquid outlet branch 121 , since the refrigerant temperature in the liquid outlet branch 121 is lower than the refrigerant temperature in the elbow structure 124 , heat absorption of the heat sink 21 is effectively achieved.

[0048] Combine Figure 5-Figure 8 Preferably, the plurality of elbow structures 124 include a first refrigerant elbow 122 and a second refrigerant elbow 123 disposed adjacent to each other; the length of the first refrigerant elbow 122 extending from the end surface of the side plate structure 11 is greater than the length of the second refrigerant elbow 123 extending from the end surface; wherein the heat sink 21 cooperates with the first refrigerant elbow 122, and the relief structure 22 cooperates with the second refrigerant elbow 123. By providing the relief structure 22 to cooperate with the second refrigerant elbow 123, the electric control box 20 is effectively prevented from colliding with the second refrigerant elbow 123, while ensuring the cooperation between the heat sink 21 and the first refrigerant elbow 122 and the tight fit between the electric control box 20 and the refrigerant pipe assembly 12.

[0049] Preferably, the side plate structure 11 and the electric control box 20 are connected by either a snap connection or a screw connection, or a combination of the two. For example, to improve the stability of the electric control box 20 when mounted to the side plate structure 11, the electric control box 20 and the side plate structure 11 can be screwed.

[0050] Preferably, a side plate structure 11 is provided with a retaining slot 111 for retaining the electric control box 20; and / or, the side plate structure 11 includes a side plate body 112 and a peripheral edge portion 113 disposed around the edge of the side plate body 112. The side plate body 112 is used to mount the refrigerant tube assembly 12, and the peripheral edge portion 113 is provided with a connection hole 114 for threaded connection with the electric control box 20. For example, the cooperation between the electric control box 20 and the retaining slot 111 achieves a pre-positioning effect. Combined with the connection hole 114 provided on the peripheral edge portion 113, when pre-positioning is achieved, the difficulty of matching the screw hole provided on the electric control box 20 with the connection hole 114 is reduced, thereby improving the efficiency of installing the electric control box 20 to the side plate structure 11.

[0051] Specifically, the limiting slot 111 is formed by bending a portion of the surrounding edge portion 113 , and the connecting hole 114 is formed on the portion.

[0052] Preferably, the electrical control box 20 includes a connecting body 23 and a fixing part 24 that cooperate with each other; the first end 231 of the connecting body 23 is connected to the side plate structure 11, and the second end 232 is provided with an installation position for assembling the heat sink 21; the fixing part 24 cooperates with the connecting body 23 to form an assembly space for encapsulating the heat sink 21 and the refrigerant pipe group 12.

[0053] Preferably, the connecting body 23 is provided with a snap-fitting groove 233 and a first matching hole arranged opposite to each other; one end of the fixing member 24 is provided with an elastic buckle 241 matching with the snap-fitting groove 233, and the other end is provided with a second matching hole connected to the first matching hole through the connecting member 30.

[0054] Preferably, the heat sink 21 is arranged on the first mating side 235 of the connecting body 23; the electronic control components of the electronic control box 20 are arranged on the second mating side 236 opposite to the first mating side 235; wherein the refrigerant tube group 12 and the second mating side 236 are staggered; and / or the side shape of the heat sink 21 used to cooperate with the refrigerant tube group 12 is adapted to the surface shape of the refrigerant tube group 12.

[0055] By staggering the second mating side 236 and the refrigerant tube assembly 12, interference of the electronic control components mounted on the second mating side 236 with the refrigerant tube assembly 12 is effectively avoided. Furthermore, by matching the side profile and surface profile of the heat sink 21, the surface area for thermal exchange between the heat sink 21 and the refrigerant tube assembly 12 is increased, thereby enhancing the cooling effect of the refrigerant tube assembly 12 on the heat sink 21, thereby ensuring stable operation of the electronic control box 20. For example, the heat sink 21 is a plate-shaped member with an arc-shaped side profile that matches the refrigerant tube assembly 12.

[0056] On the other hand, the present invention also provides an embodiment of an air conditioner. Specifically, the air conditioner includes the outdoor unit 100 in the above embodiment. Correspondingly, this embodiment can achieve the technical effects corresponding to any technical solution in the above embodiment, which will not be repeated here.

[0057] Although the present invention is disclosed as above, it is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope defined by the claims.
