Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, specifically to an intelligent control cabinet for HVAC equipment. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) equipment is a core component of heating, ventilation, and air conditioning systems, designed to regulate the indoor environment and meet human comfort or industrial production needs. Its core equipment falls into three main categories: the first is heating equipment such as boilers, heat pumps, and radiators, which generate heat by burning fuel or using electricity to provide warmth to the room; the second is ventilation equipment such as fresh air units, supply and exhaust fans, responsible for removing stale indoor air, introducing fresh air, and controlling humidity, odors, and harmful gas concentrations to ensure air quality; and the last is air conditioning equipment, including central air conditioning systems and terminal units, which regulate indoor temperature and humidity through refrigerant or water circulation to create a comfortable environment.

[0003] Patent CN222670299U discloses a control cabinet and HVAC equipment for HVAC systems, including a cabinet, a power supply module, and a control module. The power supply module supplies power to the HVAC equipment, and the control module controls or displays the operating status of the HVAC equipment. The power supply module and control module are electrically connected and integrated into the cabinet. This control cabinet and HVAC equipment, by integrating the power supply module and control module into the control cabinet, can reduce the number of parts and connecting wires while achieving power supply and control of the HVAC equipment, making assembly more convenient, debugging and maintenance time shorter, and effectively reducing production and maintenance costs. It can also optimize the layout of the equipment, making the space occupied more compact and improving the overall aesthetics.

[0004] While the above-mentioned device can effectively reduce production and maintenance costs, it still has the following shortcomings: The aforementioned device integrates the power supply module and control module into the cabinet, achieving internal integration optimization of a single cabinet. However, the cabinet is a fixed-size integrated structure. When the HVAC system needs to be expanded or reduced, it cannot be adapted by adjusting the number of cabinets. It can only be achieved by replacing the cabinets with larger or smaller ones, which has the limitations of weak on-demand adjustment capability and high repeated investment costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an intelligent control cabinet for HVAC equipment, which solves the problems of integrated cabinets being unable to be flexibly expanded and having poor adaptability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent control cabinet for HVAC equipment, including a mounting base, on which stackable equipment control cabinets are mounted. A T-shaped slide bar is symmetrically arranged on the top surface of the mounting base. The bottom surface of the equipment control cabinet is slidably mounted on the mounting base via the T-shaped slide bar. A second T-shaped slide bar, identical in shape to the first T-shaped slide bar, is arranged on the top surface of the equipment control cabinet. The uppermost equipment control cabinet has a mounting top seat connected to the second T-shaped slide bar on its top surface. Ventilation holes are provided on the left and right sides of the equipment control cabinet, and movable sealing components are installed inside the ventilation holes. The mounting base and the left and right sides of the equipment control cabinet are on the same vertical plane. An L-shaped limiting plate is provided on the right side of the mounting base, and an L-shaped limiting groove that mates with the L-shaped limiting plate is opened on the left side of the mounting base.

[0007] Furthermore, the movable enclosure component includes an enclosure plate disposed inside the ventilation hole, the enclosure plate having ventilation holes corresponding to the positions of the ventilation holes, a fixing plate extending from the front end of the bottom of the enclosure plate, the top surface of the fixing plate extending to the outside of the equipment control cabinet, the fixing plate being fixedly connected to the equipment control cabinet by mounting bolts, the equipment control cabinet having an enclosure groove for the enclosure plate to move back and forth, and the equipment control cabinet having a fixing port for the fixing plate to move back and forth.

[0008] Furthermore, the top surface of the fixing plate is flush with the outside of the equipment control cabinet. When the left and right sides of the equipment control cabinet are aligned, the two fixing plates on the inside can be fixed by the same mounting bolt, and the two equipment control cabinets are fixedly connected together by the mounting bolt.

[0009] Furthermore, a ventilation plate running vertically through the middle of the bottom surface of the equipment control cabinet is provided, and a ventilation fan is provided on the ventilation plate. A drain port running vertically through the middle of the top surface of the equipment control cabinet is provided. A base ventilation slot for use with the ventilation fan is provided in the middle of the top surface of the mounting base. A top mounting ventilation slot for use with the drain port is provided in the middle of the bottom surface of the mounting top seat. Base air inlets are provided on the front and rear sides of the base ventilation slot. Top mounting air outlets are provided on the front and rear sides of the top mounting ventilation slot.

[0010] Furthermore, dustproof nets are installed on the outer sides of the air inlet of the base and the air outlet of the top seat.

[0011] Furthermore, the top surface of the base air inlet and the top surface of the top seat air outlet are respectively provided with a base mounting port and a top seat mounting port. The dustproof net is installed by sliding up and down through the base mounting port and the top seat mounting port, and magnetic patches are provided on the inner side of the left and right ends of the dustproof net.

[0012] Furthermore, waterproof pads are installed above the base mounting port and the top mounting port.

[0013] Compared with the prior art, the present invention has the following beneficial effects: By setting T-shaped slide rail one and T-shaped slide rail two, the control cabinets can be stacked in layers and installed in a sliding manner. With the finishing design of the mounting bracket, the number of cabinets can be flexibly increased or decreased according to the control requirements of HVAC equipment. With the cooperation of L-shaped limit plates and L-shaped limit grooves, the positioning accuracy when multiple cabinets are spliced ​​left and right can be ensured. By setting a movable enclosure component, the alignment area of ​​the vent and ventilation holes can be adjusted by moving the enclosure plate back and forth, so as to achieve precise control of ventilation volume. When the left and right cabinets are attached, the two inner fixing plates can share the same mounting bolt for fixing, which not only enhances the connection strength between the cabinets, but also reduces the number of bolts used and lowers costs. By incorporating ventilation panels, fans, air inlets, base ventilation slots, and top ventilation slots, multiple stacked control cabinets form a unified heat dissipation channel, avoiding the isolated heat dissipation effect of individual cabinets. Dust filters prevent airborne dust and debris from entering the cabinet. These filters slide up and down through the base and top mounting ports and are quickly secured with magnetic fasteners at both ends, allowing maintenance personnel to easily install and remove them by hand, significantly reducing cleaning or replacement time. Waterproof pads prevent condensation and splashes from entering the cabinet through the mounting gaps, protecting internal electrical components from moisture. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] like Figures 1 to 4 As shown, an intelligent control cabinet for HVAC equipment includes a mounting base 1, on which stackable equipment control cabinets 2 are mounted. A T-shaped slide bar 101 is symmetrically arranged on the top surface of the mounting base 1. The bottom surface of the equipment control cabinet 2 is slidably mounted on the mounting base 1 via the T-shaped slide bar 101. A T-shaped slide bar 201 with the same shape as the T-shaped slide bar 101 is arranged on the top surface of the equipment control cabinet 2. The uppermost equipment control cabinet 2 has a mounting top seat 3 connected via the T-shaped slide bar 201 on its top surface. Ventilation holes 202 are provided on the left and right sides of the equipment control cabinet 2, and movable sealing components 4 are arranged inside the ventilation holes 202. The mounting base 1 and the left and right sides of the equipment control cabinet 2 are on the same vertical plane. An L-shaped limiting plate 102 is provided on the right side of the mounting base 1, and an L-shaped limiting groove 103 that cooperates with the L-shaped limiting plate 102 is opened on the left side of the mounting base 1.

[0018] like Figure 1 As shown, the control cabinet in this utility model is similar in structure to existing control cabinets. For example, patent CN222670299U discloses a control cabinet and HVAC equipment for HVAC systems. The main improvement of this utility model is that it solves the problems of integrated cabinets being unable to be flexibly expanded and having poor adaptability. Figures 1 to 4 As shown, this utility model discloses an intelligent control cabinet for HVAC equipment. Before use, the appropriate number of control cabinets 2 and mounting bases 1 can be selected according to requirements. When there is more than one mounting base 1, they can be spliced ​​together with the cooperation of L-shaped limiting plate 102 and L-shaped limiting groove 103 to ensure structural stability. Then, with the cooperation of T-shaped slide bar 101 and T-shaped slide bar 201, the stacked control cabinets 2 are installed on the mounting base 1. After stacking, the mounting top 3 is installed to complete the stacking of the control cabinets 2. Then, the operator can adjust the position of the sealing plate 401 as needed to ensure smooth ventilation inside the control cabinet 2. During the use of the equipment control cabinet 2, external airflow can enter the base ventilation slot 104 through the base air inlet 105, and enter the equipment control cabinet 2 under the push of the ventilation fan 206 on the bottom surface of the equipment control cabinet 2. Then, part of this airflow escapes through the ventilation hole 202, and the other part enters the equipment control cabinet 2 above through the air outlet 207 set in the middle of the top surface of the equipment control cabinet 2. Finally, it is dispersed from the mounting top base 3 through the top base ventilation slot 301 and the top base air outlet 302, so that the stacked multiple equipment control cabinets 2 form a unified heat dissipation channel, which can meet the heat dissipation requirements of the components in the equipment control cabinet 2 when operating under high load.

[0019] like Figure 2 and Figure 4 As shown, the movable enclosure assembly 4 includes an enclosure plate 401 disposed inside the ventilation hole 202. The enclosure plate 401 has a ventilation hole 402 corresponding to the position of the ventilation hole 202. A fixing plate 403 is provided extending from the front end of the bottom of the enclosure plate 401. The top surface of the fixing plate 403 extends to the outside of the equipment control cabinet 2. The fixing plate 403 is fixedly connected to the equipment control cabinet 2 by mounting bolts 404. The inside of the equipment control cabinet 2 is provided with an enclosure groove 203 for the enclosure plate 401 to move back and forth. The outside of the equipment control cabinet 2 is provided with a fixing opening 204 for the fixing plate 403 to move back and forth.

[0020] Specifically, when the left and right equipment control cabinets 2 are fitted together, if it is necessary to adjust the ventilation volume, the overlapping area of ​​the vent 402 and the ventilation hole 202 can be flexibly adjusted by moving the sealing plate 401 back and forth, so as to achieve step-by-step control of the ventilation volume. When the vent 402 and the ventilation hole 202 are completely aligned, the heat dissipation efficiency when the two cabinets are fitted together can be greatly improved, avoiding the problem of internal heat dissipation obstruction caused by the fitting together. In addition, in the face of humid and dusty environments or low ambient temperatures, the vent 402 and the ventilation hole 202 can be completely staggered, and the ventilation hole 202 can be completely blocked by the sealing plate 401, which can prevent the entry of external foreign objects and maintain the appropriate operating temperature of the internal components.

[0021] like Figure 1 and Figure 2 As shown, the top surface of the fixing plate 403 is flush with the outer side of the equipment control cabinet 2. When the equipment control cabinet 2 is attached to the left and right, the two fixing plates 403 on the inner side can be fixed by the same mounting bolt 404, and the two equipment control cabinets 2 are fixedly connected together by the mounting bolt 404.

[0022] Specifically, by making the top surface of the fixing plate 403 flush with the outside of the equipment control cabinet 2, the equipment control cabinet 2 can still fit together from left to right. When the equipment control cabinet 2 is fitted together from left to right, the two fixing plates 403 on the inside can be fixed by the same mounting bolt 404, which not only enhances the connection strength between the cabinets, but also reduces the amount of bolts used and lowers the cost.

[0023] like Figures 2 to 4 As shown, the bottom surface of the equipment control cabinet 2 has a vertically connected ventilation plate 205 in the middle, and a ventilation fan 206 is installed on the ventilation plate 205. The top surface of the equipment control cabinet 2 has a vertically connected air intake 207 in the middle. The top surface of the mounting base 1 has a base ventilation slot 104 for use with the ventilation fan 206 in the middle. The bottom surface of the mounting top 3 has a top mounting ventilation slot 301 for use with the air intake 207 in the middle. The base ventilation slot 104 has base air inlets 105 on the front and rear sides, and the top mounting ventilation slot 301 has top mounting air outlets 302 on the front and rear sides.

[0024] Specifically, during the ventilation and heat dissipation process of the equipment control cabinet 2, external airflow can enter the base ventilation slot 104 through the base air inlet 105, and enter the equipment control cabinet 2 under the push of the ventilation fan 206 on the bottom surface of the equipment control cabinet 2. Subsequently, part of this airflow escapes through the ventilation hole 202, and the other part enters the equipment control cabinet 2 above through the air outlet 207 set in the middle of the top surface of the equipment control cabinet 2. Finally, it is dispersed from the mounting top base 3 through the top base ventilation slot 301 and the top base air outlet 302, so that the stacked multiple equipment control cabinets 2 form a unified heat dissipation channel, avoid the heat dissipation island effect of a single cabinet, and can meet the heat dissipation requirements of the components in the equipment control cabinet 2 when operating under high load.

[0025] like Figure 2 and Figure 3 As shown, dustproof nets 5 are installed on the outer sides of the air inlet 105 on the base and the air outlet 302 on the top base.

[0026] Specifically, by installing dust filters 5 on the outside of the base air inlet 105 and the top air outlet 302, dust and debris in the air can be filtered to prevent them from entering the cabinet, thereby intercepting pollutants in advance, reducing the number of times the internal components of the cabinet need to be cleaned, and reducing operation and maintenance costs.

[0027] like Figure 1 As shown, the top surface of the base air inlet 105 and the top surface of the top seat air outlet 302 are respectively provided with a base mounting port 106 and a top seat mounting port 303. The dustproof net 5 is installed by sliding up and down through the base mounting port 106 and the top seat mounting port 303. Magnetic adhesive patches 501 are provided on the inner side of the left and right ends of the dustproof net 5.

[0028] Specifically, by opening the base mounting port 106 and the top mounting port 303, the dustproof net 5 can be installed by sliding up and down through the base mounting port 106 and the top mounting port 303. With the magnetic adhesive pads 501 at both ends, it can be quickly fixed. Maintenance personnel can complete the disassembly and assembly by hand, which greatly shortens the time for cleaning or replacing the dustproof net 5.

[0029] like Figures 1 to 3 As shown, a waterproof pad 6 is installed above the base mounting port 106 and the top mounting port 303.

[0030] Specifically, by installing waterproof pads 6 above the base mounting port 106 and the top mounting port 303, condensation and splashes in the environment can be prevented from entering the cabinet through the gaps in the mounting ports, thus protecting the internal electrical components from moisture.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
