[0033] Example 1

[0034] A wall-mounted condensing unit comprises a chassis 1, a refrigeration component and a heat dissipation component. The refrigeration component and the heat dissipation component are both arranged in a containing space in the chassis 1.

[0035] The refrigeration component is used to deliver the refrigerant medium to the refrigeration equipment, and will heat the air in the chassis 1 during operation. The heat dissipation component is used to achieve the exchange of hot and cold air inside and outside the chassis 1;

[0036] The heat dissipation component includes a fan 2, which can drive air flow to form an airflow, discharge hot air in the chassis 1 and allow air outside the chassis 1 to enter;

[0037] The chassis 1 is composed of a front side plate 11, a bottom plate 12, a side cover plate 13, a top cover plate 14 and a rear cover plate 15. Figure 1 , Figure 2 as well as Figure 4 As shown;

[0038] The front side plate 11 is composed of an air inlet plate 111 and a fan plate 112. The fan plate 112 is located above the air inlet plate 111. Figure 1 As shown;

[0039] An air inlet is provided on the surface of the air inlet plate 111;

[0040] The air inlet plate 111 is provided with a dustproof air inlet mesh plate 13 corresponding to the air inlet, which can effectively prevent dust, insects, etc. in the air from entering the chassis 1 during the air intake process. Figure 1 As shown;

[0041] In this embodiment, the dustproof air inlet mesh plate 13 is composed of a number of prismatic holes;

[0042] The fan plate 112 has an air outlet 114 on its surface. Figure 1 , Figure 3 As shown;

[0043] The fan 2 is installed in the chassis 1 and corresponds to the air outlet 114. Figure 1 , Figure 3 As shown;

[0044] The installation of the fan 2 inside the chassis 1 is a prior art and will not be described in detail here;

[0045] The refrigeration assembly includes a condenser 4, which is installed in the chassis 1 and corresponds to the air inlet plate 111 and the fan plate 112. Figure 2 , Figure 3 As shown;

[0046] When the condensing unit is running, the high-temperature and high-pressure refrigerant gas is cooled by the condenser 4, and the condenser 4 exchanges heat with the air in the surrounding chassis 1, thereby turning the air in the chassis 1 into hot air; the operation of the fan 2 can drive the air to form an airflow, and the flow direction of the airflow is as follows: Figure 2 As shown by the arrows in the figure, the hot air in the chassis 1 will be discharged from the air outlet 114 located at the top, and the air outside the chassis 1 will enter the chassis 1 from the air inlet located at the bottom. After entering the chassis 1, the air flows upward around the condenser 4 to exchange heat with it to form hot air, and then the hot air is discharged from the air outlet 114 to form an air cooling cycle.

[0047] The air inlet and the air outlet 114 are both arranged on the front side plate 11, so that the rear side or the left and right sides of the chassis 1 can be in contact with the wall 9. Figure 2As shown, the rear cover 15 of the chassis 1 is placed in close contact with the wall 9, thus avoiding the problem of the condensing unit being installed at a certain distance from the wall, thereby meeting the installation needs of some cold storages with small spaces.

[0048] In this embodiment, a fan cover 115 is installed on the outer side of the fan plate 112 corresponding to the fan 2. Figure 1 to Figure 3 As shown;

[0049] The fan cover 115 can prevent the fan 2 from being damaged by contact with external objects or human bodies when the fan 2 rotates at high speed, and can also prevent dust or debris from entering the chassis 1 from the air outlet 114 to affect the normal operation of the fan 2.

[0050] The refrigeration assembly includes a compressor 3, which is used to compress low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas;

[0051] The outlet end of the compressor 3 is connected to an oil separator 5 through a pipeline. The oil separator 5 is used to separate the lubricating oil in the gas discharged from the compressor 3 to ensure that the lubricating oil does not enter the condenser 4 and other equipment;

[0052] The refrigeration assembly includes a condenser 4, the inlet end of which is connected to an oil separator 5 through a pipeline. The condenser 4 can cool the received high-temperature and high-pressure gas. During the cooling process, the condenser 4 will exchange heat with the air in the chassis 1, so that the air in the chassis 1 becomes hot air.

[0053] The refrigeration assembly includes a liquid reservoir 6, one end of which is connected to the condenser 4 through a pipeline. The liquid reservoir 6 is used to store the condensed refrigerant liquid and plays a role in stabilizing the refrigerant cycle;

[0054] The refrigeration assembly includes a filter 7, which is installed on a pipe at one end of the liquid storage device 6. The filter 7 is used to remove impurities and moisture in the refrigerant and protect other components in the refrigeration assembly from contamination;

[0055] The refrigeration component includes a gas-liquid separator 8, which is connected to the outlet end of the liquid storage device 6 through a pipeline. The gas-liquid separator 8 is used to separate the gas and liquid in the refrigerant to ensure that the refrigerant enters the evaporator in the refrigeration equipment in a stable state;

[0056] The positions of the devices in the refrigeration assembly in the chassis 1 are as follows: Figure 3 As shown;

[0057] In this embodiment, the oil separator 5, the liquid reservoir 6, the filter 7, the compressor 3 and the gas-liquid separator 7 are all mounted and fixed on the inner side wall of the bottom plate 12. Figure 3 As shown;

[0058] In this embodiment, a chassis column 16 is provided in the chassis 1, and the chassis column 16 is fixed inside the chassis 1. Figure 3 As shown;

[0059] The chassis columns 16 are used to support and fix the components in the chassis 1 to ensure the stability of the components and prevent them from moving or vibrating inside the chassis 1;

[0060] Furthermore, the condenser 4 is horizontally mounted on the chassis column 16 .

[0061] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to achieve basically the same technical effects are all included in the protection scope of the present invention.
