Description

Technical Field

[0001] This application relates to the technical field of heat pumps, and more particularly to a heat pump unit with a multifunctional support and fixing structure. Background Technology

[0002] With the advancement of urbanization, the problem of limited installation space for heat pump units has become increasingly prominent. Traditional units generally have the following technical defects: (1) The frame structure adopts a rough layout, and the space utilization rate of each functional component is low, resulting in a large overall size of the unit, which is difficult to adapt to the installation requirements of small spaces; (2) The support frame and functional components adopt an integrated welded structure. When it is necessary to repair core components such as compressors and heat exchangers, the related structural components must be removed, which presents a maintenance problem of "affecting the whole body with a single move"; (3) During transportation, the conventional frame structure lacks compact design, which not only occupies too much loading space, but also the unreasonable distribution of rigid support points can easily lead to transportation vibration damage. Although there are solutions using split frames in the existing technology, they generally have problems such as insufficient modularity and too many connection nodes leading to a decrease in structural strength. Utility Model Content

[0003] The purpose of this application is to provide a heat pump unit with a multifunctional support and fixing structure. By integrating multiple fixing positions on the frame, it replaces the scattered fixing structure, freeing up more operable space for the unit and improving installation efficiency.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] On one hand, a heat pump unit with a multifunctional support and fixing structure is provided, including: a chassis, an electrical box, and a support structure. The electrical box is located above the chassis. The support structure includes a frame, a first folded edge, and a second folded edge. The frame extends upward from the chassis to the bottom of the electrical box to form a support. The first folded edge and the second folded edge are both disposed on the frame. The first folded edge is used to install a high-pressure shut-off valve and a low-pressure shut-off valve, and the second folded edge is used to install a heat exchanger.

[0006] Furthermore, the first folded edge is provided with a first positioning groove for positioning the high-pressure shut-off valve and a second positioning groove for positioning the low-pressure shut-off valve. The upper and lower ends of the first positioning groove and the second positioning groove are provided with first locking holes, which are used to cooperate with the high-pressure shut-off valve and the low-pressure shut-off valve for locking.

[0007] Furthermore, the frame is also provided with a first fixing part and a second fixing part at intervals, the first fixing part being used to install the water inlet pipe and the second fixing part being used to install the water outlet pipe.

[0008] Furthermore, both the first fixing part and the second fixing part are installed on the side of the frame by fasteners, and both the first fixing part and the second fixing part are provided with pipe holes, the walls of the pipe holes are provided with anti-slip structures.

[0009] Furthermore, the center distance between the first fixing part and the second fixing part is set as L, the outer diameter of the water inlet pipe is set as R1, and the outer diameter of the water outlet pipe is set as R2, wherein L=R1+R2+C, and 600mm≤C≤900mm.

[0010] Furthermore, the first folded edge is L-shaped and integrally formed on the skeleton; and / or the second folded edge is integrally formed on the skeleton.

[0011] Furthermore, it also includes a panel assembly, which is assembled with the chassis to form a housing, and a partition is provided inside the housing to divide the interior of the housing into a fan chamber and a compressor chamber, and the support structure is disposed in the compressor chamber.

[0012] Furthermore, the panel assembly includes a front panel, a side panel, and a rear panel. The front panel, the side panel, the rear panel, and the central partition are sequentially arranged to form the press cavity. The distance between the first folded edge and the side panel is d1, and the distance between the second folded edge and the rear panel is d2, wherein 60mm≤d1≤120mm and 30mm≤d2≤80mm.

[0013] Furthermore, the front panel, the side panel, the rear panel, and the central partition are detachably connected.

[0014] Furthermore, the second folded edge is provided with a second locking hole for locking in conjunction with the heat exchanger.

[0015] The beneficial effects of this application are as follows: By integrating the first folded edge (for installing high and low pressure shut-off valves) and the second folded edge (for installing heat exchangers) into the frame, the traditional scattered fixed structure is replaced, reducing component redundancy, significantly improving space utilization, and freeing up more operating space inside the unit. At the same time, the frame extends from the chassis to the bottom of the electrical box to form a continuous support frame, enhancing the overall mechanical strength, reducing the risk of component loosening due to vibration, optimizing load distribution, and extending the service life of the unit.

[0016] Furthermore, the modular frame design supports rapid positioning and installation of key components (such as shut-off valves and heat exchangers), simplifying the assembly process and reducing labor costs. During maintenance, targeted maintenance can be achieved through partial disassembly, avoiding the impact of overall disassembly on unit stability. Moreover, the compact design reduces unit size, improves transportation efficiency, and adapts to diverse transport vehicles, reducing logistics costs. Attached Figure Description

[0024] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] like Figures 1-5 As shown, this application embodiment aims to provide a heat pump unit with a multi-functional support and fixing structure. Through the innovative frame 301 design, the space utilization, mechanical strength, assembly efficiency, and maintenance convenience of the unit are significantly improved. The heat pump unit mainly consists of a chassis 1, an electrical box 2, and a support structure 3. The electrical box 2 is located above the chassis 1, while the support structure 3 includes a frame 301 extending upwards from the chassis 1 to the bottom of the electrical box 2, and a first flange 302 and a second flange 303 disposed on the frame 301. The first flange 302 is specifically used to install a high-pressure shut-off valve and a low-pressure shut-off valve, while the second flange 303 is used to install a heat exchanger.

[0028] This design integrates the first folded edge 302 and the second folded edge 303 through the frame 301, replacing the traditional scattered fixed structure, reducing component redundancy, and thus significantly improving space utilization, freeing up more operating space inside the unit. Simultaneously, the frame 301 extends from the chassis 1 to the bottom of the electrical box 2, forming a continuous support frame, effectively enhancing the overall mechanical strength of the unit. This not only reduces the risk of component loosening due to vibration but also optimizes load distribution and extends the unit's service life.

[0029] Furthermore, the modular frame 301 design supports rapid positioning and installation of key components, such as shut-off valves and heat exchangers, greatly simplifying the assembly process and reducing labor costs. During maintenance, targeted maintenance can be achieved through partial disassembly, avoiding the impact of overall disassembly on unit stability and improving maintenance efficiency. The compact design also reduces the unit's size, improves transportation efficiency, and is compatible with various transport vehicles, reducing logistics costs. In summary, the heat pump unit of this application, through its multi-functional support and fixing structure, achieves multiple advantages, including efficient space utilization, enhanced mechanical strength, improved assembly and maintenance convenience, and reduced transportation costs.

[0030] It is worth noting that the heat pump unit in this embodiment fully considers the installation requirements and stability of the high-pressure and low-pressure shut-off valves when designing the first folded edge 302. To accurately position and securely install these two key components, the first folded edge 302 is specially equipped with a first positioning groove 306 for positioning the high-pressure shut-off valve and a second positioning groove 307 for positioning the low-pressure shut-off valve. This design not only ensures the accuracy of the shut-off valves during installation but also greatly improves the ease of installation.

[0031] To further enhance the connection stability between the shut-off valve and the first flange 302, first locking holes 308 are cleverly provided at both the upper and lower ends of the first positioning groove 306 and the second positioning groove 307. These first locking holes 308 cooperate with the corresponding structures on the high-pressure shut-off valve and the low-pressure shut-off valve to achieve a stable lock through a locking mechanism, effectively preventing the shut-off valve from loosening or shifting during operation, thereby ensuring the safe and stable operation of the heat pump unit.

[0032] Furthermore, the frame 301 is also provided with a first fixing part 304 for installing the water inlet pipe, and a second fixing part 305 for installing the water outlet pipe, with the first fixing part 304 and the second fixing part 305 spaced apart. In this design, the addition of a first fixing part 304 for installing the water inlet pipe and a second fixing part 305 for installing the water outlet pipe to the frame 301, with these two fixing parts spaced apart, allows the water inlet and outlet pipes to be directly fixed to the frame 301, forming a stable integrated structure. This not only reduces the use of additional pipe support components and further optimizes the internal space layout of the unit, improving space utilization, but also enhances the structural stability of the entire unit, effectively reducing the risk of pipe loosening or displacement due to vibration or external forces, and improving the reliability and safety of the unit; simultaneously, the first fixing part... The spacing between 304 and the second fixing part 305 avoids mutual interference between the inlet and outlet pipes, ensuring the rationality and orderliness of the pipeline layout, facilitating installation and maintenance. During installation, workers can quickly fix the inlet and outlet pipes in their respective positions without the need for complex support structures 3, simplifying the assembly process and reducing labor costs. When maintaining or replacing pipes, it is also possible to quickly locate and operate, reducing downtime and improving the availability and maintenance efficiency of the unit. In addition, the neatly fixed inlet and outlet pipes also enhance the cleanliness and aesthetics of the unit's interior, further optimizing the overall design of the unit.

[0033] Furthermore, both the first fixing part 304 and the second fixing part 305 are installed on the side of the frame 301 using fasteners, and both the first fixing part 304 and the second fixing part 305 have pipe holes 310, the walls of which are provided with anti-slip structures. The first fixing part 304 and the second fixing part 305 are specifically designed for installing inlet and outlet pipes, and are installed on the side of the frame 301 using fasteners. This installation method not only ensures the stability of the fixing parts but also greatly facilitates the installation and disassembly of the pipes. Moreover, the pipe holes 310 on both the first fixing part 304 and the second fixing part 305 are carefully designed to ensure the accuracy and stability of the pipe installation. In particular, the walls of the pipe holes 310 are also provided with anti-slip structures, which effectively prevents the pipes from slipping or loosening during installation, thereby ensuring the stability and safety of the water system. The anti-slip structure not only improves the tightness of the connection between the pipe and the fixed part, but also further enhances the overall reliability and durability of the heat pump unit's water system. During long-term use, this design effectively reduces problems such as leaks and seepage caused by loose or slipping pipes, thereby extending the unit's service life and reducing maintenance costs.

[0034] The first fixing part 304 and the second fixing part 305 have identical structures, both having a square cross-section. The first fixing part 304 and the second fixing part 305 are located on the same side, with the first fixing part 304 positioned above the first folded edge 302, and the second fixing part 305 positioned close to the chassis 1 and below the vertical height of the second folded edge 303. The positions of the first fixing part 304 and the second fixing part 305 can be adjusted according to different installation schemes and are not fixed.

[0035] Furthermore, the center distance between the first fixing part 304 and the second fixing part 305 is set as L, the outer diameter of the inlet pipe is set as R1, and the outer diameter of the outlet pipe is set as R2, where L = R1 + R2 + C, and 600mm ≤ C ≤ 900mm. This additional distance C is carefully set between 600mm and 900mm to ensure sufficient space between the two pipes to avoid mutual interference or collision during installation, operation, or maintenance. This design not only optimizes the internal spatial layout of the heat pump unit, making the water system clearer and more efficient, but also fully considers the convenience of later maintenance and repair. Sufficient distance C provides operators with ample operating space, allowing them to more easily inspect, replace, or repair the inlet and outlet pipes, thereby reducing maintenance difficulty and time costs.

[0036] As an optional specific implementation, the first fixing part 304 and the second fixing part 305 are integrally formed into the frame 301. This design makes the fixing of the inlet and outlet pipes more stable and reliable. Since the first fixing part 304 and the second fixing part 305 are integrated with the frame 301, they form a structural whole, thereby enhancing the structural strength and stability of the entire unit. This integrated molding method not only reduces the number of connection points between components, lowering the risk of failure due to loose connections, but also simplifies the production process and improves production efficiency. Furthermore, the integrated molding design reduces material usage, lowers production costs, and makes the unit's appearance cleaner and more aesthetically pleasing. In practical applications, this design can effectively improve the performance and service life of the heat pump unit, bringing users a more stable and efficient user experience.

[0037] Meanwhile, the first folded edge 302 is L-shaped and integrally formed with the frame 301, and the second folded edge 303 is integrally formed with the frame 301. This design further enhances the structural stability and overall performance of the heat pump unit. By integrally forming the first folded edge 302 and the second folded edge 303 with the frame 301, not only are the connection points between components reduced, lowering the risk of failure due to loose connections, but production efficiency is also improved and production costs are reduced. The integrally formed folded edge design makes the installation of the high-pressure shut-off valve, low-pressure shut-off valve, and heat exchanger more secure, ensuring the reliability and safety of the unit during operation. At the same time, this design also optimizes the internal space layout of the unit, making the layout between components more compact and orderly, further improving space utilization. In addition, the integrally formed folded edge design also makes the appearance of the unit cleaner and more aesthetically pleasing, improving the overall quality of the product.

[0038] Furthermore, the one-piece molding design significantly improves production efficiency and reduces production costs. During manufacturing, the folded edge and frame 301 are integrally molded using processes such as stamping or casting, greatly reducing assembly steps and time, thereby improving the overall efficiency of the production line. Simultaneously, the one-piece molding design also reduces assembly errors between components, improving the overall quality of the product. For the first folded edge 302, its L-shaped design not only provides sufficient installation space but also ensures the stability of the high-pressure and low-pressure shut-off valves during installation. By precisely controlling the stamping and bending angle at 90°±2° or 90°±5° (adjusted according to actual needs), the fitting accuracy between the first folded edge 302 and the high-pressure and low-pressure shut-off valves is further improved, ensuring the reliability and safety of the unit during operation. This one-piece molding folded edge design also optimizes the internal space layout of the unit. The layout between components is more compact and orderly, not only improving space utilization but also facilitating later maintenance and repair work. At the same time, the clean and aesthetically pleasing appearance design enhances the overall quality and market competitiveness of the product.

[0039] In some embodiments, the system further includes a panel assembly 4, which is assembled with the chassis 1 to form a housing. A partition 5 is provided inside the housing, dividing the interior into a fan chamber and a compressor chamber. The support structure 3 is located in the compressor chamber. This design, through the assembly of the panel assembly 4 and the chassis 1, forms a complete housing structure, which not only protects the various components inside the unit but also improves the overall aesthetics and safety of the unit. The partition 5 effectively divides the internal space of the housing, making the fan chamber and compressor chamber independent, avoiding mutual interference between the fan and compressor, and optimizing the airflow organization and heat exchange efficiency inside the unit. The support structure 3, located inside the compressor chamber, provides stable support for key components such as the compressor, ensuring the stability and reliability of the unit during operation, and further improving the overall performance and service life of the heat pump unit.

[0040] Specifically, the panel assembly 4 includes a front panel 401, a side panel 402, and a rear panel 403, which, together with the central partition 5, enclose the compressor chamber. The front panel 401 is located at the front of the unit, while the side panels 402 and rear panel 403 are located on the sides and rear of the unit, respectively. The central partition 5 divides the internal space of the housing into a fan chamber and a compressor chamber, ensuring the functional independence of the two chambers. The support structure 3 is positioned at the corner of the compressor chamber, away from the front panel 401 and the central partition 5. This positioning allows the support structure 3 to effectively provide stable support for the electrical box 2 and the structure at the right rear of the unit. The corner position can be understood as the distance d1 between the first folded edge 302 and the side panel 402, and the distance d2 between the second folded edge 303 and the rear panel 403, where 60mm ≤ d1 ≤ 120mm and 30mm ≤ d2 ≤ 80mm. Based on this distance constraint, the entire support structure 3 is positioned at the corner.

[0041] This design effectively distributes the load, which was originally concentrated on the side panels 402, rear panel 403, and top, thereby comprehensively improving the overall structural strength of the unit. During transportation, this structural design makes the unit more stable, reducing the risk of damage caused by vibration or external forces. Simultaneously, during unit operation, the support structure 3 significantly enhances its stability, ensuring smooth operation of the unit.

[0042] During maintenance, after removing the right-side panel 402, the frame 301 is located at the right edge of the side panel 402, freeing up ample space for easy maintenance of components such as pipes, water pumps, electronic expansion valves, and exhaust valves. Furthermore, the shut-off valve and inlet / outlet water pipes, fixed to the frame 301 and facing right, are also more conveniently accessible for use or disassembly. If a major overhaul is required, all panels around the compressor chamber can be removed. In this case, the frame 301 provides support for the electrical box 2, stably holding it in place and preventing deformation due to gravity. This design significantly improves the operational space for maintenance, making the maintenance process more efficient and convenient.

[0043] Preferably, the front panel 401, side panel 402, rear panel 403, and central partition 5 are detachably connected. This design makes the assembly and disassembly of the heat pump unit more convenient. During transportation and installation, the detachable connection allows the unit to be disassembled into smaller parts, facilitating transport and handling, and reducing transportation costs and damage risks. At the installation site, workers can quickly assemble the various components according to actual needs to form a complete unit structure. Furthermore, the detachable connection facilitates the maintenance and repair of the unit. When a component inside the unit needs repair or replacement, only the corresponding panel needs to be removed, eliminating the need for large-scale disassembly of the entire unit, greatly improving maintenance efficiency and reducing downtime. Simultaneously, this design also makes cleaning and maintenance of the unit more convenient. Workers can easily remove the panels to thoroughly clean the inside of the unit, ensuring normal operation and extending its service life.

[0044] It is worth mentioning that the second flange 303 is provided with a second locking hole 309 that engages with the heat exchanger for locking. This design plays an important role in the assembly and use of the heat pump unit. The heat exchanger can be stably locked onto the second flange 303 through the second locking hole 309, which not only enhances the installation stability of the heat exchanger but also improves heat exchange efficiency. The design of the second locking hole 309 makes the installation and disassembly of components more convenient, simplifies the assembly process, and improves assembly efficiency. When maintenance or repair is required, the locking hole 306 also facilitates the quick disassembly and replacement of components, reducing downtime and improving the availability and maintenance efficiency of the unit.

[0045] Furthermore, the frame 301 is detachably mounted to the chassis 1 using fasteners. This design ensures both a secure connection between the frame 301 and the chassis 1 and facilitates disassembly. The use of fasteners ensures that the frame 301 is firmly fixed to the chassis 1 during normal operation, providing stable support for the entire support structure 3. Simultaneously, the detachable connection allows for easy removal of the frame 301 from the chassis 1 during maintenance or repair, eliminating the need for extensive disassembly of the entire unit. This design not only improves the efficiency of maintenance and repair but also reduces the risk of damage to the unit during disassembly and installation, further enhancing the reliability and service life of the unit.
