Description

Technical Field

[0001] This application relates to the field of refrigeration equipment, and in particular to a compressor assembly and a freezer. Background Technology

[0002] In related technologies, when a variable frequency compressor is installed on a freezer, the environmental conditions of some freezers are relatively harsh, requiring enhanced structural strength at the connection between the inverter box and the compressor. In typical freezers, multiple bolts are used to ensure connection strength, but these bolt connections are prone to tearing. Some solutions use multiple reinforcing ribs at the bolt connection, but these ribs occupy excessive space, making it difficult to mold the inverter box at this point and resulting in a high failure rate. Therefore, there is a need to improve the connection structure between the inverter box and the compressor. Utility Model Content

[0020] The following is for reference. Figures 1-8 A compressor assembly 1000 according to an embodiment of the present invention is described.

[0021] According to the first aspect of the present invention, the compressor assembly 1000, such as Figures 1-3 As shown, it includes: compressor body 200, mounting base 500 and inverter box 100.

[0022] The compressor body 200 is provided with a wiring terminal 201, and the mounting base 500 is connected to the compressor body 200. The mounting base 500 is provided with a clearance opening 501 facing the wiring terminal 201. The mounting base 500 includes a support plate 510 and a first hook 520 located above the support plate 510.

[0023] The inverter box 100 includes a box body 10 and a boss box 60 disposed on the side of the box body 10 facing the compressor body 200. The boss box 60 is disposed on the support plate 510 and has a connection port 601. The wiring terminal 201 is located at the connection port 601 to connect to the inside of the box body 10. The first hook 520 is engaged with the boss box 60 via the connection port 601.

[0024] The compressor assembly 1000 also includes a mounting fastener 71 that passes through the mounting base 500 and connects to the boss box 60.

[0025] In a refrigeration system, the inverter box 100 (commonly referred to as an inverter module or inverter) is one of the core components. Its main function is to achieve precise control of cooling / heating capacity by adjusting the operating frequency of the compressor, thereby achieving energy saving and rapid temperature regulation. The inverter box 100 includes an inverter board (circuit board) located inside the box body 10. The wiring terminals 201 of the compressor body 200 are located at the connection port 601 of the boss box 60 and are connected to the inverter board inside the box body 10, realizing the inverter control of the compressor body 200 by the inverter box 100.

[0026] In this application, the inverter box 100 is installed on the compressor body 200, and the bottom of the inverter box 100 is suspended. Therefore, the structural strength requirement at the connection between the inverter box 100 and the compressor body 200 is high.

[0027] By providing a mounting base 500 on the compressor body 200 and a boss box 60 on the inverter box 100, with the boss box 60 protruding from the box body 10 instead of being directly connected to the compressor body 200 via the box body 10, it is ensured that the boss box 60 and the mounting base 500 are not interfered with by the box body 10 during assembly. This allows for a larger contact area between the two, resulting in high connection reliability and reducing excessive shaking caused by airflow. Furthermore, the connection point is formed by a terminal 201 on the compressor body 200 passing through the mounting base 500 and inserting into the connection port 601 of the boss box 60. The terminal 201 is protected by the mounting base 500 and the boss box 60, improving the safety and stability of signal communication.

[0028] In this application, a support plate 510 and a first hook 520 are provided on the mounting base 500. During assembly, the boss box 60 can be directly placed on the support plate 510. Since the boss box 60 has a connection port 601 for inserting the terminal block 201, the first hook 520 can simultaneously hook the boss box 60 through the connection port 601, thus positioning the inverter box 100 on the mounting base 500. After that, the mounting fasteners 71 are installed, and the inverter box 100 is completely fixed. This arrangement not only ensures that the inverter box 100 is firmly installed on the compressor body 200, but also reduces the number of mounting fasteners 71 required, thereby reducing the labor intensity of installing the inverter box 100 and shortening the assembly time. In addition, the boss box 60 is not only supported by the support plate 510, but also hooked by the first hook 520, which disperses the connection stress at the boss box 60, making it less prone to deformation and disengagement after long-term connection.

[0029] Here, the first hook 520 can be fixed in any position; it can be fixed on the top of the boss box 60 or on the side of the boss box 60.

[0030] The terminal block 201 is used to connect an external AC power source (commonly 220V or 380V) to the motor windings (such as the starting winding and running winding) inside the compressor body 200, providing electrical energy for motor operation. Some types of compressor bodies 200 have 3 terminal blocks 201, while others may have 6 terminal blocks 201. The terminal blocks 201 are assembled inside the frequency converter box 100, and their connection status is controlled by the circuit board of the frequency converter box 100.

[0031] In some embodiments, such as Figure 2 and Figure 4 As shown, the boss box 60 includes: a boss bottom wall 61, a first boss connecting wall 62, a second boss connecting wall 63, a boss top wall 64, and a boss side wall 65.

[0032] like Figure 4 As shown, the first boss connecting wall 62 is vertically disposed on one side of the boss bottom wall 61, and the second boss connecting wall 63 is vertically disposed on the other side of the boss bottom wall 61. The boss top wall 64 is located above the boss bottom wall 61, and its two ends are connected to the first boss connecting wall 62 and the second boss connecting wall 63. The boss side wall 65 is located on the side of the boss box 60 facing the compressor body 200, and the boss side wall 65 connects the boss bottom wall 61, the boss top wall 64, the first boss connecting wall 62, and the second boss connecting wall 63. The connection port 601 is provided on the boss side wall 65.

[0033] Thus, the boss box 60 is rectangular in shape and open on the side facing the main body of the inverter box 100 (i.e., the box body 10), which facilitates the forming of the boss box 60 and the connection between the boss box 60 and the box body 10.

[0034] The bottom wall 61 of the boss is located on the support plate 510. The inverter box 100 mainly presses its weight onto the mounting base 500 through the bottom wall 61 of the boss. The mounting base 500 provides relatively stable support for the boss box 60. When the bottom wall 61 of the boss is under load, it is supported by the first boss connecting wall 62, the second boss connecting wall 63, the top wall of the boss 64, and the side wall of the boss, making it less prone to deformation.

[0035] Specifically, such as Figures 4-6 As shown, the mounting base 500 also includes a mounting motherboard 530 and an upper folding plate 540.

[0036] like Figure 6 As shown, the motherboard 530 is connected to the compressor body 200, as follows. Figure 5 As shown, the mounting motherboard 530 has a clearance opening 501, and the support plate 510 is connected to the bottom of the mounting motherboard 530.

[0037] The upper folding plate 540 is connected to the upper end of the mounting motherboard 530 and is inclined upward in the direction towards the box body 10. The upper end of the upper folding plate 540 extends into the connection port 601, and the first hook 520 is connected to the upper folding plate 540.

[0038] Here, the mounting base 500 connects the upper folding plate 540 and the support plate 510 into a whole through the mounting motherboard 530, and the upper folding plate 540 and the support plate 510 support the boss box 60.

[0039] By setting the upper folding plate 540 to be tilted upward in the direction toward the box body 10, when supporting the boss side wall 65, the boss side wall 65 is guided toward the mounting motherboard 530, so that the boss box 60 is closer to the mounting motherboard 530, reducing the chance of the boss box 60 falling off the mounting base 500 after long-term operation.

[0040] Furthermore, such as Figure 6 As shown, the boss box 60 also includes a reinforcing top wall 66, which is connected to the boss side wall 65 along the upper edge of the connection port 601. The reinforcing top wall 66 is inclined downward in the direction towards the compressor body 200, and is in contact with the upper folding plate 540. In this way, the contact area between the reinforcing top wall 66 and the upper folding plate 540 is large, and when the upper folding plate 540 supports the boss box 60, the contact stress on the upper folding plate 540 and the reinforcing top wall 66 is relatively low, reducing the possibility of deformation or tearing of the upper folding plate 540 and the reinforcing top wall 66 after long-term operation.

[0041] Optionally, the upper folding plate 540 and the reinforcing top wall 66 can both be straight inclined plates for easy processing. Of course, in some designs, the upper folding plate 540 and the reinforcing top wall 66 can both be curved plates to facilitate more even stress distribution.

[0042] In some alternative embodiments, such as Figure 4 As shown, the boss box 60 also includes two reinforcing sidewalls 67, which are respectively connected to the boss sidewalls 65 along the two side edges of the connection port 601. The mounting motherboard 530 is sandwiched between the two reinforcing sidewalls 67. This improves the structural strength of the edge of the connection port 601, reduces stress concentration, and lowers the risk of deformation and tearing. It also improves the sealing of the connection port 601, preventing external insects from entering the inverter box 100 through the connection port 601. Moreover, since the connection port 601 needs to be aligned with the mounting base 500 during assembly, the direction of the docking operation is the same as the direction of the operation of inserting the mounting motherboard 530 between the two reinforcing sidewalls 67. Therefore, one action can accomplish two purposes simultaneously, making the operation simple and the assembly effect high.

[0043] Furthermore, the upper ends of both reinforcing sidewalls 67 are connected to the reinforcing top wall 66, which makes it easier to form a sealed assembly.

[0044] Specifically, such as Figure 4 and Figure 8 As shown, the first boss connecting wall 62 includes an upper connecting wall 621, a folded wall 622, and a lower connecting wall 623. The upper end of the upper connecting wall 621 is connected to the top wall 64 of the boss, and a reinforcing side wall 67 is connected to the upper connecting wall 621 on the side facing the compressor body 200. The folded wall 622 is connected to the lower end of the upper connecting wall 621 and is bent towards the second boss connecting wall 63. The lower connecting wall 623 is located below the upper connecting wall 621, and the lower end of the lower connecting wall 623 is connected to the folded wall 622.

[0045] The folded wall 622 and the lower connecting wall 623 abut against the mounting motherboard 530. The mounting fastener 71 is assembled on the first boss connecting wall 62, specifically, the mounting fastener 71 is connected to the lower connecting wall 623.

[0046] The first boss connecting wall 62 is bent, and the bent plate forms a "corner support," which significantly improves the overall rigidity and increases the resistance to deformation. The fastener 71 is located close to the bend, avoiding stress concentration at the connection or load-bearing point and reducing the risk of fracture. While achieving the same structural strength, the bent plate can reduce material thickness or overall size by optimizing the cross-sectional shape. Compared to traditional solutions that require numerous ribs inside the boss box to achieve the same structural strength, this application simplifies the rib placement and reduces the difficulty of processing and forming.

[0047] Specifically, after the lower connecting wall 623 bends toward the second protrusion connecting wall 63, as... Figure 4 As shown, the lower connecting wall 623 forms an assembly groove 624 on the side away from the second boss connecting wall 63. The mounting base 500 is connected to the assembly groove 624, and the fastener 71 is installed, making it easy to hide in appearance and improving the overall aesthetics.

[0048] In some embodiments, such as Figure 8 As shown, the first boss connecting wall 62 is provided with a first connecting hole 603 for connecting with the mounting fastener 71. The mounting fastener 71 can be a threaded connector such as a bolt or a rivet.

[0049] Specifically, the boss box 60 also includes a ring rib 681, which surrounds the first connecting hole 603. It is understood that the first connecting hole 603 is a weak point in the structure. When bolts, rivets, or other connecting parts transmit loads, the edge of the hole will experience high stress due to localized force concentration (especially under tensile and shear forces). In this application, the ring rib 681 increases the material thickness and stiffness around the hole, diffusing stress from the hole edge to a wider area, reducing localized stress peaks, and extending the structural lifespan. This improves the load-bearing capacity of the connection, optimizes stress distribution, and protects the mounting fastener 71 and the first boss connecting wall 62.

[0050] Optionally, circumferential reinforcement 681 can be provided on one or both sides of the lower connecting wall 623.

[0051] Specifically, the boss box 60 also includes a strip rib 682. Part of the strip rib 682 is located on the first boss connecting wall 62 and connected to the ring rib 681, while the other part extends to the box wall of the box body 10. In other words, the strip rib 682 extends outward from the ring rib 681 (for example, radially along the first connecting hole 603), further transferring the stress dispersed by the ring rib 681 to a more distant area of ​​the structure, essentially forming a "stress transfer channel" that allows the entire structure to share the load, preventing stress concentration at the ring rib 681. By extending the strip rib 682 to the box wall of the box body 10, the strip rib 682 transfers stress from the boss box 60 to the box body 10, utilizing the more robust box body 10 to disperse concentrated stress. This reduces the structural stress borne by the boss box 60 and simplifies its structure.

[0052] Optionally, strip ribs 682 can be provided on one or both sides of the lower connecting wall 623.

[0053] Furthermore, such as Figure 5 As shown, the mounting base 500 also includes a side plate 560 that connects to the side of the mounting motherboard 530, such as... Figure 8 As shown, the side retaining plate 560 is positioned corresponding to the lower connecting wall 623, i.e., located in the mounting groove 624. The side retaining plate 560 has holes for mounting fasteners 71. Here, there can be one or two side retaining plates 560. Using two side retaining plates 560 allows for adaptation to different types of inverter boxes 100. When the box is heavy, it has two first connecting holes 603, requiring the two side retaining plates 560 to be connected.

[0054] In some embodiments, such as Figure 5 As shown, the mounting base 500 also includes a second hook 550 and a side plate 560. The second hook 550 and the side plate 560 are connected to the horizontal sides of the mounting motherboard 530. The second hook 550 and the side plate 560 place a part of the boss box 60 between them, which serves as a lateral limiting function.

[0055] Specifically, the side latch 560 abuts against the boss box 60, such as against the first boss connecting wall 62. The second latch 550 abuts against a reinforcing side wall 67.

[0056] The side plate 560 is connected to the boss box 60 by a fastener 71. The end of the second hook 550 is hooked onto the boss box 60, which not only limits its position in the lateral direction but also prevents it from rotating.

[0057] Specifically, such as Figure 3 and Figure 4As shown, the boss box 60 is provided with a locking hole 602, which is spaced apart from the connection port 601 and located on the side of the connection port 601 away from the side locking plate 560. The second hook 550 is engaged in the locking hole 602. This can reduce the stress on the boss box 60 at the edge of the connection port 601 and avoid deformation caused by the second hook 550 pressing on the boss box 60 during vibration and impact. Moreover, the second hook 550 can hold the boss box 60, which is equivalent to an elastic arm, making assembly easier and providing a certain degree of elastic buffering function.

[0058] Specifically, such as Figure 3 As shown, the locking hole 602 is partially located on the bottom wall 61 of the boss and partially on the side wall 65 of the boss, and the locking hole 602 is L-shaped. During assembly, the boss box 60 is moved closer to the mounting base 500 while being installed from top to bottom. This allows the locking hole 602 to be inserted directly into the second hook 550, so that the hook head of the second hook 550 extends into the boss box 60 and hooks onto the side wall 65 of the boss. Thus, the assembly process is very simple and quick.

[0059] Furthermore, in order to improve the structural strength of the boss box 60 at the snap hole 602, the boss box 60 also includes a reinforcing rib 683. The reinforcing rib 683 connects to the boss side wall 65 on one side and the boss bottom wall 61 on the other side, so that when the boss side wall 65 is subjected to tensile stress, the stress can be transferred to the boss bottom wall 61.

[0060] Furthermore, such as Figure 8 As shown, there are two reinforcing ribs 683 located on both sides of the locking hole 602. One of the reinforcing ribs 683 connects to a reinforcing sidewall 67. The double reinforcement allows for a smoother stress transmission path and is beneficial for stress dispersion.

[0061] Specifically, the locking hole 602 on the bottom wall 61 of the boss not only facilitates assembly but also drainage. A second hook 550 is provided at the locking hole 602 to effectively prevent insects from entering.

[0062] In this application, optionally, the first hook 520, the second hook 550, the mounting fastener 71, and the support plate 510 are located on different sides of the connection port 601, and the first hook 520 and the second hook 550 face different directions. This arrangement prevents the inverter box 100 from moving and rotating relative to the compressor body 200 in any direction when the inverter box 100 shakes relative to the compressor body 200 due to vibration or external impact, achieving six degrees of freedom constraint. This effectively ensures the reliability of the connection between the inverter box 100 and the terminal block 201, and improves the reliability of power supply and control of the compressor body 200.

[0063] Furthermore, by positioning the first hook 520, the second hook 550, the mounting fastener 71, and the support plate 510 on different sides of the connection port 601, the stress on each side of the edge of the connection port 601 is relatively reduced, lowering the stress peak and reducing the risk of tearing of the boss box 60 at the connection port 601. This eliminates the need for an overly complex shape for the boss box 60, reducing the need for excessive ribs, simplifying manufacturing, and decreasing the volume it occupies.

[0064] Optionally, such as Figure 7 As shown, the bottom wall 61 of the boss has a bottom opening 611, which is connected to the connection port 601. This opening increases the elastic deformation capacity, making it easier to squeeze the wiring terminal 201 and other components into the connection port 601 during assembly. The support plate 510 is sealed above the bottom opening 611 to prevent insects from entering.

[0065] In some embodiments, the inverter box 100 includes: a box body 10, a circuit board and a heat sink. The box body 10 has an opening on one side and sockets on opposite sides of the opening. The circuit board is installed inside the box body 10 and has electrical components. The heat sink includes a main heat sink and auxiliary heat sinks connected to both ends of the main heat sink. The main heat sink is located at the opening to enclose the box body 10, and the auxiliary heat sinks at both ends are respectively inserted into the sockets on both sides.

[0066] The inverter box 100 can be used in the compressor assembly 1000 of the refrigeration equipment. The box body 10 of the inverter box 100 is equipped with a circuit board. The electrical components on the circuit board generate a lot of heat when they are working and have a heat dissipation requirement. If the heat dissipation of the electrical components is not timely, it may lead to a decrease in the working stability of the circuit board or even damage to the circuit board.

[0067] Therefore, the inverter box 100 in this embodiment of the application is provided with a heat sink, which includes a main heat sink plate located at the opening to enclose the box body 10. On the one hand, the box body 10 has an opening on the side facing the heat sink, allowing the heat sink to contact the interior of the box body 10 for heat exchange, which reduces the heat transfer path and facilitates the transfer of heat to the heat sink for heat dissipation, thereby improving heat dissipation efficiency. On the other hand, the main heat sink plate covers the opening, providing a larger area for heat exchange, which further improves the heat dissipation efficiency of the heat sink plate.

[0068] Furthermore, the radiator also includes auxiliary heat dissipation plates connected to both ends of the main heat dissipation plate. The radiator is formed into a U-shaped structure, with the main heat dissipation plate located at the opening and the auxiliary heat dissipation plates inserted into the slots on opposite sides of the opening.

[0069] By configuring the heat sink with auxiliary heat sinks at both ends of the main heat sink, not only can the heat exchange area of ​​the heat sink be increased and the heat dissipation efficiency of the heat sink be improved, but the auxiliary heat sink inserted into the socket can also improve the installation stability of the heat sink and the housing 10, improve the stability of the main heat sink encapsulating the housing 10, and help improve the working reliability of the circuit board inside the housing 10.

[0070] In addition, by encapsulating the main heat sink 10 with the secondary heat sink and inserting it into the housing 10, the structure for installing the heat sink can be reduced, thus simplifying the structure, saving materials for the housing 10 and reducing manufacturing costs.

[0071] Optionally, the housing 10, circuit board, and heat sink are all vertically arranged, with the main heat sink facing the circuit board. This design helps to make the housing 10 flat, occupying less space, and allows the heat sink to utilize a large heat dissipation area, which is beneficial to improving the heat dissipation efficiency of the heat sink; when water comes into contact with the inverter box 100, the water will flow downward under the action of gravity, making it easy to drain and preventing it from accumulating on the surface of the inverter box 100.

[0072] According to an embodiment of this utility model, the inverter box 100 features a U-shaped heat sink, with the main heat sink sealing the opening and the secondary heat sink plugging into the box body 10. Both the main and secondary heat sinks can exchange heat, increasing the heat exchange area of ​​the heat sink and reducing the heat transfer path between the circuit board and the heat sink, thereby improving the heat dissipation effect of the inverter box 100. Furthermore, it also improves the installation stability of the heat sink and the box body 10, simplifies the structure, and reduces manufacturing costs.
