[0003] In specific related technologies, the air-conditioning outdoor unit is divided into a fan cavity and a compressor cavity by a partition, and the electronic control box is installed on the partition. Although the heat dissipation effect of various electronic control components inside the electronic control box is achieved by cooperating with the heat sink and the refrigerant pipe, the coordination between the partition, the heat sink and the refrigerant pipe is not reasonably arranged in the related technology, resulting in reduced heat dissipation efficiency. Utility Model Content

[0004] The technical problem solved by the present invention is that in a specific related technology, the air-conditioning outdoor unit is divided into a fan cavity and a compressor cavity by a partition, and the electronic control box is installed on the partition. Although the heat dissipation effect of various electronic control components inside the electronic control box is achieved by the cooperation between the heat dissipation plate and the refrigerant pipe, the cooperation between the partition, the heat dissipation plate and the refrigerant pipe is not reasonably arranged in the related technology, resulting in reduced heat dissipation efficiency.

[0005] In order to solve the above problems, the utility model provides an outdoor unit, comprising: a shell, a partition plate is provided in the shell to divide the internal space of the shell into a fan chamber and a compressor chamber; a heat sink and an electric control box that cooperate with each other, and the electric control box is arranged on one side of the partition plate; a refrigerant pipe group, the refrigerant pipe group is used to connect the heat exchanger and the compressor of the outdoor unit, and the refrigerant is transported between the heat exchanger and the compressor by the refrigerant pipe group; wherein, at least one refrigerant pipe constituting the refrigerant pipe group is clamped between the heat sink and the partition plate.

[0006] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: Specifically, by sandwiching the refrigerant tube between the heat sink and the partition plate, on the one hand, the refrigerant flowing in the refrigerant tube dissipates heat from the heat sink, thereby dissipating heat from the various electronic control components in the electronic control box; on the other hand, since the refrigerant tube is in direct contact with the partition plate, the heat dissipation surface area for thermal interaction between the refrigerant tube and the external environment is increased to a certain extent, thereby further improving the heat dissipation efficiency of the refrigerant tube; in addition, since the heat sink is externally arranged on the outside of the electronic control box, it is prevented from being housed inside the electronic control box, resulting in difficulty in heat dissipation. Therefore, by rationally arranging the matching positions between the partition plate, the heat sink and the refrigerant tube, the heat dissipation efficiency of the various electronic control components in the electronic control box is reasonably improved.

[0007] In one embodiment of the present invention, the refrigerant pipe sandwiched between the heat sink and the partition plate is defined as a first refrigerant pipe; the first refrigerant pipe is fixed to one side of the partition plate.

[0008] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: compared with the assembly method of fixing the first refrigerant tube in the electrical control box, combined with the specific dimensions of the partition plate and the electrical control box, since the size of the partition plate is larger than that of the electrical control box, by fixing the first refrigerant tube to the partition plate, the stability of the installation of the first refrigerant tube can be improved to a certain extent. In addition, since the electrical control box is also installed on the partition plate, if the first condenser tube is installed on the electrical control box, the stability of the combination of the two is also limited by the stability of the combination of the electrical control box and the partition plate. Therefore, by fixing the first refrigerant tube to the partition plate, the stability of the installation of the first refrigerant tube is effectively improved.

[0009] In one embodiment of the present invention, a first receiving groove for limiting the first refrigerant tube is provided on one side of the partition plate; and / or a second receiving groove adapted to the first refrigerant tube is provided on one side of the heat sink close to the partition plate.

[0018] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: specifically, combined with the characteristic that the air flow channel can change the flow direction of the air flow, that is, it can be understood that there is at least one bending part in the air flow channel, which is blocked by the bending part, thereby effectively reducing the possibility of water droplets in the outdoor environment directly entering the compressor cavity; in addition, by setting up the air flow channel, the hot air flow in the compressor cavity can be effectively guided into the fan cavity, thereby improving the heat dissipation efficiency in the compressor cavity.

[0045] Specifically, by sandwiching the refrigerant tube between the heat sink 21 and the partition plate 11, on the one hand, the refrigerant flowing in the refrigerant tube dissipates heat from the heat sink 21, thereby dissipating heat from the various electronic control components within the electrical control box 22. On the other hand, since the refrigerant tube is in direct contact with the partition plate 11, the heat dissipation surface area for thermal interaction between the refrigerant tube and the external environment is increased to a certain extent, thereby further improving the heat dissipation efficiency of the refrigerant tube. In addition, since the heat sink 21 is externally arranged on the outside of the electrical control box 22, it is prevented from being housed inside the electrical control box 22, which would make it difficult to dissipate heat. Therefore, by rationally arranging the matching positions between the partition plate 11, the heat sink 21, and the refrigerant tube, the heat dissipation efficiency of the various electronic control components within the electrical control box 22 is reasonably improved.

In addition, since the electrical control box 22 is also installed on the partition plate 11, if the first condenser tube is installed on the electrical control box 22, the stability of the combination of the two is also limited by the stability of the combination of the electrical control box 22 and the partition plate 11. Therefore, by fixing the first refrigerant tube 31 to the partition plate 11, the stability of the installation of the first refrigerant tube 31 is effectively improved.

[0053] Specifically, combined with the characteristic that the airflow channel 231 can change the flow direction of the airflow, it can be understood that there is at least one bending portion in the airflow channel 231, which is blocked by the bending portion, thereby effectively reducing the possibility of water droplets in the outdoor environment directly entering the compressor cavity 13; in addition, by setting up the airflow channel 231, the hot air flow in the compressor cavity 13 can be effectively guided into the fan cavity 12, thereby improving the heat dissipation efficiency in the compressor cavity 13.
