[0001] The utility model relates to the technical field of HVAC equipment, in particular to an outdoor unit of HVAC equipment. Background Art

[0002] With the continuous improvement of people's living standards and the rapid development of the construction industry, HVAC equipment plays an increasingly important role in people's daily life and work. As an important part of the HVAC system, the performance and function of the outdoor unit of HVAC equipment directly affect the operation effect of the entire HVAC system and the user experience.

[0003] In traditional outdoor units of HVAC equipment, there are generally problems such as inconvenient installation, poor flexibility, low heat dissipation efficiency, and insufficient protection performance. For example, during the installation process, due to the fixed installation position and height of the outdoor unit, it is difficult to flexibly adjust according to the actual installation environment, which brings great difficulties to the installation work. At the same time, traditional outdoor units usually adopt natural convection or simple fan heat dissipation methods in terms of heat dissipation, with low heat dissipation efficiency, which easily causes the outdoor unit to malfunction in high-temperature environments, affecting the service life and performance of the equipment. In addition, traditional outdoor units lack effective protection measures and are easily eroded by external dust, debris, rainwater, etc., affecting the normal operation of the equipment. Therefore, we propose an outdoor unit of HVAC equipment. Content of the Utility Model

[0025] In an embodiment of the present utility model: a first threaded hole 13 is opened at the top of the connecting plate 12, the threaded rod 8 passes through the first threaded hole 13 and is threadedly connected.

[0026] In an embodiment of the present utility model: A rotary motor 18 is fixed to the rear end of the outdoor unit body 1.

[0027] In an embodiment of the present utility model: The front end of the transmission shaft of the rotary motor 18 is connected to a rotating rod 20. Wind blades 21 are evenly arranged on the surface of the rotating rod 20.

[0028] In an embodiment of the present utility model: Ventilation openings 4 are evenly opened at the front end of the shielding plate 3.

[0029] In an embodiment of the present utility model: A control switch box 10 is fixed to the right side of the outdoor unit body 1. A display screen and buttons are sequentially embedded and installed on the right side of the control switch box 10 from top to bottom.

[0030] Example 1. Please refer to the attached Figure 1 - attached Figure 4 In an air conditioner installation project in a residential community, this kind of outdoor unit of the heating and ventilation equipment was adopted. First, the shielding plate 3 was inserted into the slot 2 at the front end of the outdoor unit body 1. The ventilation openings 4 can not only ensure air circulation but also block dust and sundries. Through the bolts 15 and nuts 16 on the connecting frame 5, the outdoor unit body 1 was initially fixed at a suitable position on the exterior wall of the building. Then, the long slot 9 of the adjusting frame 7 was connected to the connecting plate 12 at the rear end of the outdoor unit body 1. The lifting motor 6 at the top of the adjusting frame 7 was started to drive the threaded rod 8 to rotate. Since the threaded rod 8 is threadedly connected to the first threaded hole 13 at the top of the connecting plate 12, the outdoor unit body 1 can be adjusted in height according to the installation space and heat dissipation requirements. Finally, the rotary motor 18 was turned on through the button on the control switch box 10, and the rotating rod 20 drove the wind blades 21 to rotate, accelerating the air flow around the outdoor unit and improving the heat dissipation efficiency.

[0031] Example 2. Please refer to the attached Figure 1 - attached Figure 4 In a heating and ventilation system renovation project of a large commercial office building, this new type of outdoor unit of the heating and ventilation equipment was applied. The installer first inserted the shielding plate 3 into the slot 2 to provide preliminary protection for the outdoor unit. Then, the connecting frame 5 was fixed to the pre-set installation bracket using bolts 15 and nuts 16. After inserting the connecting plate 12 into the long slot 9 of the adjusting frame 7, the lifting motor 6 was used to precisely adjust the outdoor unit to the ideal height position to adapt to the complex building layout and pipeline connection requirements. During the operation of the equipment, the staff can monitor the operation status and parameters of the outdoor unit in real time through the display screen of the control switch box 10. When the external environmental temperature is relatively high, the rotary motor 18 is turned on, and the rotation of the wind blades 21 strengthens the air convection, ensuring the stable and efficient operation of the outdoor unit, providing continuous and stable heating and cooling supply for the office building, and effectively improving the performance and reliability of the entire heating and ventilation system.

[0032] Specifically, the design of the baffle plate 3 can effectively prevent external dust, debris and rainwater from entering the interior of the external unit. The slot 2 is convenient for installation and disassembly, easy for cleaning and maintenance, and protects internal components to extend the service life of the equipment. Secondly, the adjustment frame 7 is matched with the lifting motor 6 and the threaded rod 8, and the height of the external unit can be flexibly adjusted to adapt to different installation environments and needs. For example, the external unit can be raised in areas with limited space to avoid interference. The cooperation of the connecting frame 5 with the nut 16 and the bolt 15 makes the installation and disassembly of the external unit more convenient, facilitates the subsequent maintenance and replacement work, and reduces maintenance costs.

[0033] Specifically, by rotating the motor 18 to drive the rotating rod 20 and the fan blades 21 to rotate, the air flow around the external unit can be accelerated, the heat dissipation efficiency of the external unit can be improved, the stable operation of the equipment in a high temperature environment can be ensured, and performance degradation or failure caused by overheating can be effectively prevented. The service life of the equipment is extended, and the cooperation between the long groove 9 and the connecting plate 12 and the connection between the threaded rod 8 and the first threaded hole 13 realizes the flexible adjustment of the height and angle of the external unit, facilitates installation and subsequent maintenance, and improves the applicability of the equipment.

[0034] Working principle:

[0035] First, when the height of the machine is adjusted, the lifting motor 6 at the top of the adjustment frame 7 is started. The transmission shaft of the lifting motor 6 rotates in the first circular hole 11, driving the threaded rod 8 fixed at its bottom end to rotate. Since the threaded rod 8 passes through the first threaded hole 13 at the top of the connecting plate 12 and the two are threadedly connected, when the threaded rod 8 rotates, the connecting plate 12 will move up and down along the long groove 9, thereby driving the height adjustment of the external machine body 1 to achieve the best installation and heat dissipation position. In addition, during the operation of the external machine, when the external machine body 1 needs to strengthen the heat dissipation, the rotating motor 18 is started. The transmission shaft of the rotating motor 18 passes through the second circular hole 19 at the rear end of the external machine body 1, driving the rotating rod 20 connected to the front end to rotate, and the fan blades 21 evenly arranged on the rotating rod 20 rotate accordingly, accelerating the air flow around the external machine body 1 and improving the heat dissipation efficiency. The control switch box 10 is used to control the operation of the lifting motor 6 and the rotating motor 18, and monitor the working status of the external machine. The display screen can display the relevant operating parameters of the external machine. The user can operate and regulate the operation of the motor and other functions of the device through buttons. At this point, the entire workflow ends.
