Description

Technical Field

[0001] This utility model relates to the field of refrigeration electrical technology, and mainly to a refrigeration device. Background Technology

[0002] Refrigeration equipment is a device that maintains a constant low temperature to store goods, and it is widely used in modern life and industrial production. For example, a freezer has a refrigeration compartment inside, which creates a refrigerated environment for storing goods.

[0003] The bottom of the freezer has a compressor chamber, which houses the compressor. Currently, due to the small space in the compressor chamber of the freezer, the condenser in the refrigeration system is usually not installed in the compressor chamber, but rather in the foam layer between the cabinet and the liner.

[0004] However, installing the condenser in the foam layer will occupy the product volume of the freezer, thereby reducing the space utilization of the freezer. If the condenser is installed in the compressor chamber, the ventilation performance of the condenser in the narrow compressor chamber is low, resulting in low heat dissipation efficiency, which can easily affect the cooling efficiency of the freezer. Summary of the Invention The purpose of this invention is to provide a refrigeration device that can improve ventilation performance within a compact compressor chamber.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: One aspect of this application provides a refrigeration device, including a housing forming an outer shell of the refrigeration device; a compressor chamber is provided at the bottom of the housing; a condensing assembly including a condenser disposed in the compressor chamber; a fan disposed in the compressor chamber, with the fan and the condenser arranged opposite to each other; a fan bracket disposed in the compressor chamber, with the fan and the condenser respectively disposed on opposite sides of the fan bracket; wherein the housing has a first sidewall, the outer sidewall of the first sidewall being recessed to form a support groove, and the side of the first sidewall facing the compressor chamber corresponding to the position of the support groove is formed A boss abuts against the fan bracket to divide the compressor chamber into a first compartment and a second compartment. The first compartment and the second compartment are located on opposite sides of the fan bracket and are connected internally through the fan bracket. A first air inlet is provided on the side wall of the support groove near the first compartment, and the first air inlet connects the first compartment to the outside of the housing. When the fan is running, air outside the housing can enter the first compartment through the support groove and the first air inlet, and then flow to the second compartment through the condenser and the inside of the fan bracket.

[0006] The above technical solution has the following advantages or beneficial effects: By placing the fan bracket in the compressor chamber, and arranging the fan and condenser on opposite sides of the fan bracket, the fan bracket, fan, and condenser can be integrated to form a compact structure, enabling efficient installation of the entire condensing assembly within a limited space and further improving the space utilization of the compressor chamber. Furthermore, a support groove is recessed in the first sidewall to form a boss, which abuts against the fan bracket, dividing the compressor chamber into a first compartment and a second compartment. The first and second compartments are connected internally through the fan bracket, forming an orderly airflow channel. Without the need for an additional condenser cooling duct structure, orderly airflow can occur along the first and second compartments within the compressor chamber, reducing disordered air diffusion and optimizing the ventilation structure, resulting in a more compact and rational layout of the entire refrigeration unit. Moreover, by placing the first air inlet on the sidewall of the support groove, not only can the air inlet area be expanded, thereby increasing the amount of air entering the first compartment, but also the amount of air entering the first compartment can be further increased. Furthermore, by providing a first air inlet on the side wall of the support groove, the first air inlet can make full use of the three-dimensional space of the support groove, which is conducive to expanding the air intake area without increasing the overall appearance size of the box, thereby increasing the amount of air entering the first compartment. In addition, the first air inlet is located in the support groove, which can prevent the first air inlet from being blocked by other obstacles on the first side wall, thus reducing the air intake of the compressor chamber. The setting of the first air inlet can provide more cold air for heat exchange for the condenser, improving the ventilation and heat dissipation performance of the condenser in the compact compressor chamber.

[0007] In some embodiments of this application, a refrigeration device is provided, the refrigeration device further comprising a compressor chamber cover, the compressor chamber cover being disposed on the first side wall, the outer side wall of the compressor chamber cover being recessed to form the support groove, and the inner side wall of the compressor chamber cover facing the compressor chamber forming the boss.

[0008] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by forming a support groove in the outer wall of the compressor chamber cover, and forming a protrusion on the inner wall of the compressor chamber cover corresponding to the support groove, the compressor chamber cover can abut against the fan bracket, dividing the internal space of the compressor chamber into a first chamber and a second chamber. Without adding additional air duct components to the compressor chamber, the compressor chamber cover, together with the fan bracket, defines the first chamber as an air inlet channel. As the air flows from the first chamber to the second chamber, it can pass more concentratedly through the condenser and the fan bracket, forming an effective heat exchange cycle. Moreover, it makes full use of the small space inside the compressor chamber, making the layout of each component more compact and reasonable, and improving the space utilization rate of the compressor chamber.

[0009] In some embodiments of this application, a refrigeration device is provided, wherein the compressor chamber cover is provided with a second air inlet on one side of the first chamber body, the second air inlet connects the first chamber body with the outside of the box body, and the second air inlet is located at the peripheral edge of the support groove.

[0010] Another technical solution described above has the following advantages or beneficial effects: A second air inlet is provided on one side of the compressor compartment hood located within the first compartment, providing an additional air inlet for external air to enter the first compartment, thereby increasing the airflow into the compressor chamber. Furthermore, since the second air inlet is located within a support groove, the support groove can increase the gap between itself and the mounting surface. Even when the space between the freezer and the mounting surface is limited, the combined arrangement of the first and second air inlets allows external air to enter the compressor chamber more smoothly, thus maintaining ventilation within the compressor chamber and preventing localized poor heat dissipation.

[0011] In some embodiments of this application, a refrigeration device is provided, wherein the compressor chamber cover is provided with an air outlet on one side of the second chamber body, the air outlet connects the second chamber body and the outside of the box body, and the air outlet is located on the side of the support groove away from the first air inlet.

[0012] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: When the fan starts, the air outside the box can enter the first chamber through the first air inlet, then flow through the condenser and take away the heat on the surface of the condenser before entering the second chamber, and finally be discharged from the air outlet. In this process, the fan can form an airflow in the compressor chamber to efficiently dissipate heat from the condenser and promptly discharge the heat in the compressor chamber to the outside of the box.

[0013] In some embodiments of this application, a refrigeration device is provided, wherein the housing has a second sidewall located on the other side of the first compartment, the second sidewall being adjacent to the first sidewall, and one side of the second sidewall being connected to the first sidewall; the second sidewall is provided with a third air inlet, the third air inlet connecting the first compartment to the outside of the housing.

[0014] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by providing a third air inlet on the second side wall, the second side wall is located on the other side of the first chamber and adjacent to the first side wall, and the third air inlet and the first air inlet are on different sides, it is beneficial for airflow to enter the first chamber from different directions. This not only helps to increase the total amount of air entering the first chamber, but also allows air to enter the first chamber from multiple angles. Setting air inlets on different sides can improve the heat dissipation effect in the compressor chamber, avoid the situation of poor local heat dissipation of the condenser, and improve the overall heat dissipation effect.

[0015] In some embodiments of this application, a refrigeration device is provided, the refrigeration device including a ventilation component disposed on a second side wall; the ventilation component is recessed toward the first compartment to form a ventilation groove, and the groove wall of the ventilation groove is provided with the third air inlet.

[0016] Another technical solution described above has the following advantages or beneficial effects: By providing a third air inlet on the side wall of the ventilation slot, the third air inlet can fully utilize the three-dimensional space of the ventilation slot, which is beneficial to increasing the air intake area without increasing the overall size of the housing, thereby increasing the amount of air entering the first chamber. Furthermore, the third air inlet is located within the support slot, which can prevent the air intake of the compressor chamber from being reduced due to the second side wall being blocked by the mounting surface. The third air inlet provides more sufficient cold air for heat exchange with the condenser, improving the ventilation and heat dissipation performance of the condenser within the compact compressor chamber.

[0017] In some embodiments of this application, a refrigeration device is provided, the refrigeration device further comprising a sealing element disposed around the periphery of the fan bracket, the sealing element comprising a first sealing portion, a second sealing portion and a third sealing portion connected in sequence, the first sealing portion being clamped between the fan bracket and the boss, the second sealing portion being clamped between the top wall of the compressor chamber and the top of the fan bracket, and the third sealing portion being clamped between the side of the fan bracket away from the boss and the side wall of the compressor chamber.

[0018] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by setting the first sealing part, the second sealing part and the third sealing part respectively to seal against different positions of the fan bracket, the airflow can flow more efficiently and orderly along the first and second chambers defined between the fan bracket and the boss, which improves the airflow circulation efficiency in the compressor chamber. At the same time, it reduces the problem of turbulence and eddies caused by the gas flowing through the gap between the fan bracket and the side wall of the compressor chamber, and makes the gas flow in the compressor chamber according to the predetermined channel, reducing the noise in the heat dissipation process.

[0019] In some embodiments of this application, a refrigeration device is provided, the refrigeration device further comprising a compressor disposed in a second chamber, the compressor being disposed opposite to the fan and located on the side of the fan away from the condenser; the refrigeration device includes a first delivery pipe, the inlet end of the condenser being located at the top of the condenser, the first delivery pipe being connected between the liquid outlet end of the compressor and the inlet end of the condenser, the first delivery pipe being passed through the fan support along the top wall of the compressor chamber, and the first delivery pipe being clamped between the second sealing part and the fan support.

[0020] Another technical solution described above has the following advantages or beneficial effects: the inlet end of the condenser is located at the top of the condenser, and the refrigerant flowing to the condenser from the compressor can be transported downwards from the top of the condenser. Due to gravity, the refrigerant can naturally fill the pipes of the condenser, improving the refrigerant transport efficiency and helping to reduce the energy consumption of the refrigeration system. Moreover, by clamping the first delivery pipe between the second sealing part and the fan bracket, the second sealing part can seal the gap between the fan bracket and the top wall of the compressor chamber, while also sealing the outside of the first delivery pipe located at the top of the fan bracket, preventing the installation of the first delivery pipe from affecting the sealing effect between the two sides of the fan bracket and the compressor chamber.

[0021] In some embodiments of this application, a refrigeration device is provided, the refrigeration device including a filter connected to the outlet end of the condenser, the filter being located in a second chamber; the refrigeration device including a second delivery pipe connected between the outlet end of the condenser and the filter, the second delivery pipe passing through the top wall of the compressor chamber and onto the fan support, the second delivery pipe being clamped between the second sealing part and the fan support.

[0022] Another technical solution described above has the following advantages or beneficial effects: by placing the filter in the second compartment, the impact of heat generated by the condenser on the filter can be reduced. When the fan starts, the airflow in the first compartment can flow into the second compartment, and the airflow in the second compartment can dissipate heat and cool the filter, reducing the temperature of the refrigerant flowing to the evaporator, which is beneficial to improving the heat absorption effect of the evaporator, thereby improving the overall cooling efficiency of the refrigeration system.

[0023] In some embodiments of this application, a refrigeration device is provided, wherein the fan bracket is provided with an air outlet, the air inlet of the fan is arranged facing the air outlet, and the condenser is located at the air outlet; the first chamber and the second chamber are connected through the air outlet.

[0024] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: When the condenser is installed at the air outlet of the fan bracket, when the fan is started, the airflow formed in the first compartment can flow to the second compartment through the gap of the condenser or the gap between the condenser and the side wall of the air outlet. In this way, during the process of the airflow in the first compartment flowing to the second compartment, the airflow can effectively carry away the heat on the surface of the condenser, thereby reducing the temperature of the condenser and improving the heat dissipation and ventilation effect in the compressor chamber, which is conducive to improving the refrigeration performance of the refrigeration system.

The following uses a freezer as an example to describe in detail the improved technical solution of the refrigeration device in the embodiments of the invention.

[0031] Figure 1 This is a perspective view of a refrigeration device according to an embodiment of this application.

[0032] like Figure 1 As shown, the refrigeration device provided in this embodiment of the present invention includes a housing 1. The housing 1 can adopt a hollow structure such as a cuboid. The housing 1 forms the outer shell of the refrigeration device. It should be noted that the housing 1 can also adopt a hollow shell structure of other shapes.

[0033] Figure 2 for Figure 1 A cross-sectional view.

[0034] like Figure 2 As shown, in some embodiments, the interior of the housing 1 may form a refrigeration chamber 100 with a top opening. Multiple refrigeration chambers 100 may be provided.

[0035] In some embodiments, the refrigeration device may include a liner (not shown in the figure). The liner may be disposed inside the housing 1. A refrigeration chamber 100 may be provided inside the liner. A foaming space is formed between the liner and the housing 1. When foaming material is filled into the foaming space, it can effectively insulate the refrigeration chamber 100.

[0036] like Figure 2 As shown, in some embodiments, the refrigeration device may include a door 11. The door 11 is disposed on the top front side of the housing 1 and covers the top opening of the refrigeration compartment 100 for opening and closing the refrigeration compartment 100.

[0037] It should be noted that multiple doors 11 can be installed. Each door 11 can be installed in a one-to-one correspondence with a refrigeration room 100. Multiple doors 11 can open and close a single refrigeration room 100 simultaneously. A single door 11 can also open and close multiple refrigeration rooms 100 simultaneously.

[0038] In some embodiments, the refrigeration device may include a refrigeration system. The refrigeration system may be located inside the cabinet 1. The refrigeration system is used to provide cold air to the interior of the refrigerator to maintain a low-temperature environment in each refrigeration compartment 100.

[0039] Figure 3 for Figure 1 An exploded image.

[0040] like Figure 3 As shown, in some embodiments, the bottom of the housing 1 may be provided with a compressor chamber 101, and some components of the refrigeration system may be installed in the compressor chamber 101.

[0041] like Figure 3 As shown, in some embodiments, the refrigeration system includes a compressor 4. The compressor 4 serves as the power source for the refrigeration cycle, drawing in low-temperature, low-pressure refrigerant gas and compressing it into a high-temperature, high-pressure gas. The compressor 4 can then supply the high-temperature, high-pressure refrigerant to the condenser 21.

[0042] Figure 4 for Figure 2 Cross-sectional view of the intermediate pressure chamber.

[0043] like Figure 4 As shown, in some embodiments, the refrigeration system includes a condenser assembly 2. The condenser assembly 2 may include a condenser 21, which may be located within the compressor chamber 101. The condenser 21 receives the refrigerant flowing out from the compressor 4, cooling the high-temperature, high-pressure refrigerant gas from the compressor 4 and converting it into a liquid state. The condenser 21 can transfer heat from the refrigerant to the surrounding air, thus lowering the temperature of the refrigerant.

[0044] In some embodiments, the refrigeration system includes a throttling device (not shown). The condenser 21 can deliver condensed refrigerant to the throttling device. The throttling device may be a capillary tube. The throttling device can be used to reduce the pressure of the refrigerant.

[0045] In some embodiments, the refrigeration system includes an evaporator (not shown). A throttling device can deliver a throttled and depressurized refrigerant into the evaporator. The evaporator can be used for the refrigerant vapor to evaporate and boil, thereby absorbing heat from the surrounding medium.

[0046] In some embodiments, the compressor 4, condenser 21, throttling device, and evaporator can be connected in sequence to form a refrigeration circuit. The refrigerant can circulate within the refrigeration circuit to achieve refrigeration of the refrigeration chamber 100.

[0047] like Figure 4 As shown, in some embodiments, the condenser assembly 2 may include a fan 22, which is located inside the compressor chamber 101 and is arranged opposite to the condenser 21. The inlet or outlet of the fan 22 may be directed towards the condenser 21. When the fan 22 is running, it creates an airflow within the compressor chamber 101, accelerating the airflow around the condenser 21. Furthermore, the airflow passing through the condenser 21 provides excellent heat dissipation for the condenser 21.

[0048] like Figure 4 As shown, in some embodiments, the condenser assembly 2 may include a fan bracket 23, which is located within the compressor chamber 101. A fan 22 and a condenser 21 are respectively located on opposite sides of the fan bracket 23. Both the fan 22 and the condenser 21 are mounted on the fan bracket 23, which provides stable support for them. Furthermore, by integrating the fan 22 and the condenser 21 onto the fan bracket 23, the fan 22, condenser 21, and fan bracket 23 can be compactly installed together, avoiding space waste caused by dispersed arrangement of components. This not only improves space utilization within the compressor chamber 101 but also allows the airflow generated by the fan 22 to directly and effectively blow onto the condenser 21, improving its heat dissipation efficiency.

[0049] Figure 5 for Figure 1 Another schematic diagram.

[0050] like Figure 4 and Figure 5As shown, in some embodiments, the housing 1 has a first sidewall 12, the outer sidewall of the first sidewall 12 is recessed to form a support groove 102, and a boss 13 is formed on the side of the first sidewall 12 facing the press chamber 101 corresponding to the support groove 102. The boss 13 is located inside the press chamber 101. Specifically, the outer sidewall of the first sidewall 12, i.e., the sidewall away from the press chamber 101, is recessed, and the inner sidewall of the first sidewall 12, i.e., the sidewall inside the press chamber 101, forms a boss corresponding to the support groove 102.

[0051] The boss 13 abuts against the fan bracket 23 to divide the compressor chamber 101 into a first chamber 1011 and a second chamber 1012. The first chamber 1011 and the second chamber 1012 are respectively located on opposite sides of the fan bracket 23 and are connected internally through the fan bracket 23. Specifically, the first chamber 1011 and the second chamber 1012 can be connected through the gap between the fan bracket 23 and the condenser 21 or through the gap within the condenser 21, so that the airflow between the first chamber 1011 and the second chamber 1012 can be correspondingly connected.

[0052] The support groove 102 has a first air inlet 103 on its side wall near the first chamber 1011, which connects the first chamber 1011 to the outside of the housing 1. When the fan 22 is running, air from outside the housing 1 can enter the first chamber 1011 through the support groove 102 and the first air inlet 103, and then flow to the second chamber 1012 through the condenser 21 and the fan bracket 23.

[0053] Specifically, the support groove 102 recessed on the first sidewall 12 forms a boss 13 on one side of the compressor chamber 101, which abuts against the fan bracket 23, thereby dividing the compressor chamber 101 into a first chamber 1011 and a second chamber 1012. The first chamber 1011 and the second chamber 1012 are respectively located on opposite sides of the fan bracket 23. The boss 13 and the fan bracket 23 cooperate to achieve spatial separation of the compressor chamber 101, thereby defining the air duct structure. The first chamber 1011 and the second chamber 1012 can be connected through the inside of the fan bracket 23, thereby forming an airflow channel between the first chamber 1011 and the second chamber 1012. When the fan 22 is started, the air outside the housing 1 can enter the first chamber 1011 through the first air inlet 103 to form an airflow, and after passing through the condenser 21, it is drawn into the second chamber 1012 by the fan 22, and finally discharged outside the compressor chamber 101. During the heat dissipation process of condenser 21, the fan bracket 23 and boss 13 physically separate the internal space of compressor chamber 101, allowing the airflow entering compressor chamber 101 to flow along the defined first chamber 1011 through condenser 21 to the second chamber 1012, forming an orderly airflow circulation. This effectively avoids occupying the space of compressor chamber 101 by setting up a specific condenser 21 heat dissipation duct structure in compressor chamber 101, and also effectively avoids disorderly air diffusion in compressor chamber 101, enhancing the heat exchange effect of condenser 21 surface.

[0054] Furthermore, by providing a first air inlet 103 on the side wall of the support groove 102, the first air inlet 103 can make full use of the three-dimensional space of the support groove 102, which is beneficial to increase the air intake area without increasing the overall appearance size of the housing 1, thereby increasing the amount of air entering the first chamber 1011. In addition, the first air inlet 103 is located in the support groove 102, which can prevent the first air inlet 103 from being blocked by other obstacles on the first side wall 12, thereby reducing the air intake of the compressor chamber 101. The first air inlet 103 can provide more cold air for heat exchange to the condenser 21, thereby improving the ventilation and heat dissipation performance of the condenser 21 in the compact compressor chamber 101.

[0055] In current freezer products, due to the small space in the compressor chamber 101, the condenser 21 in the refrigeration system is usually installed in the foam layer between the cabinet 1 and the liner. This occupies the product volume of the freezer, thus reducing the space utilization rate. However, if the condenser 21 is installed inside the compressor chamber 101, the ventilation performance of the condenser 21 in the narrow compressor chamber 101 is low, resulting in low heat dissipation efficiency and easily affecting the refrigeration efficiency of the freezer.

[0056] In this application, by setting the fan bracket 23 inside the compressor chamber 101, and arranging the fan 22 and condenser 21 on opposite sides of the fan bracket 23, the fan bracket 23, the fan 22 and the condenser 21 can be integrated together to form a compact structure. Compared with the dispersed installation method, the redundant space for component installation can be effectively reduced, the space inside the compressor chamber 101 can be fully utilized, the entire condensing assembly 2 can be installed efficiently in a limited space, and the space utilization rate of the compressor chamber 101 can be further improved. This avoids the condenser 21 occupying the foaming space of the cabinet 1, and increases the effective space inside the freezer that can be used to store items.

[0057] Furthermore, the first sidewall 12 has a recessed support groove 102 forming a boss 13. The boss 13 abuts against the fan bracket 23, dividing the compressor chamber 101 into a first compartment 1011 and a second compartment 1012. The first compartment 1011 and the second compartment 1012 are connected internally through the fan bracket 23, forming an orderly airflow channel. With a heat dissipation duct structure that eliminates the need for an additional condenser 21, orderly airflow is achieved within the compressor chamber 101 along the first compartment 1011 and the second compartment 1012, reducing disordered air diffusion within the compressor chamber 101 and optimizing the ventilation structure of the compressor chamber 101. This makes the layout of the entire refrigeration unit more compact and rational. Moreover, by placing the first air inlet 103 on the sidewall of the support groove 102, not only can the air inlet area be expanded, thereby increasing the amount of air entering the first compartment 1011, but also further increasing the amount of air entering the first compartment 1011. Furthermore, by providing a first air inlet 103 on the side wall of the support groove 102, the first air inlet 103 can make full use of the three-dimensional space of the support groove 102, which is beneficial to increase the air intake area without increasing the overall appearance size of the housing 1, thereby increasing the amount of air entering the first chamber 1011. In addition, the first air inlet 103 is located in the support groove 102, which can prevent the first air inlet 103 from being blocked by other obstacles on the first side wall 12, thereby reducing the air intake of the compressor chamber 101. The first air inlet 103 can provide more cold air for heat exchange to the condenser 21, thereby improving the ventilation and heat dissipation performance of the condenser 21 in the compact compressor chamber 101.

[0058] In some embodiments, multiple first air inlets 103 may be provided, and the multiple first air inlets 103 are distributed at intervals on the sidewall of the support groove 102.

[0059] like Figure 4 As shown, in some embodiments, the fan bracket 23 may be provided with an air outlet 201. The air outlet 201 may extend through the opposite sides between the fans 22, with the air inlet end of the fan 22 facing the air outlet 201, and the condenser 21 located at the air outlet 201; the first chamber 1011 and the second chamber 1012 are connected through the air outlet 201.

[0060] When the condenser 21 is installed at the air outlet 201 of the fan bracket 23 and the fan 22 is started, the airflow formed in the first compartment 1011 can flow to the second compartment 1012 through the gap of the condenser 21 or the gap between the condenser 21 and the side wall of the air outlet 201. In this way, during the process of the airflow in the first compartment 1011 flowing to the second compartment 1012, the airflow can effectively carry away the heat on the surface of the condenser 21, thereby reducing the temperature of the condenser 21 and improving the heat dissipation and ventilation effect in the compressor chamber 101, which is beneficial to improving the refrigeration performance of the refrigeration system.

[0061] Figure 6 for Figure 4 A schematic diagram of the compressor compartment cover; Figure 7 for Figure 6 A diagram of the back side.

[0062] like Figure 4 , Figure 6 and Figure 7 As shown, in some embodiments, the refrigeration device may include a compressor compartment cover 14. A mounting port may be provided on the first side wall 12, and the compressor compartment cover 14 is disposed on the first side wall 12 and covers the mounting port 108, thereby covering the mounting port 108.

[0063] The outer side wall of the press chamber cover 14 is recessed to form a support groove 102, and the inner side wall of the press chamber cover 14 facing the press chamber 101 forms a boss 13.

[0064] Specifically, a support groove 102 is recessed into the outer wall of the compressor compartment cover 14, and a protrusion 13 is formed on the inner wall of the compressor compartment cover 14 corresponding to the support groove 102. This allows the compressor compartment cover 14 to abut against the fan bracket 23, dividing the internal space of the compressor chamber 101 into a first chamber 1011 and a second chamber 1012. Without adding additional air duct components within the compressor chamber 101, the compressor compartment cover 14, in conjunction with the fan bracket 23, defines the first chamber 1011 as an air intake channel. As air flows from the first chamber 1011 to the second chamber 1012, it passes more concentratedly through the condenser 21 and the fan bracket 23, forming an effective heat exchange cycle. Furthermore, it fully utilizes the limited space within the compressor chamber 101, making the layout of each component more compact and rational, thus improving the space utilization rate of the compressor chamber 101. In this way, even when the compressor 4 and the condenser 21 are simultaneously arranged within the narrow compressor chamber 101 of the freezer, good heat dissipation can still be achieved.

[0065] like Figure 3 and Figure 6As shown, in some embodiments, the compressor chamber cover 14 located on one side of the first chamber body 1011 may be provided with a second air inlet 104. The second air inlet 104 connects the first chamber body 1011 with the outside of the box body 1, and the second air inlet 104 is located at the peripheral edge of the support groove 102.

[0066] Specifically, a second air inlet 104 is provided on one side of the compressor chamber 14 located in the first chamber 1011, providing an additional air inlet 201 for air from outside the chamber 1 to enter the first chamber 1011, thereby increasing the air intake of the compressor chamber 101 and further improving the heat dissipation effect inside the compressor chamber 101.

[0067] Specifically, the support groove 102 is provided with a first air inlet 103 on the side near the first compartment 1011, and a second air inlet 104 is provided at the periphery of the support groove 102. When the freezer is installed against the wall with one side of the first side wall 12, the second air inlet 104 is located in the support groove 102, which can increase the gap between the support groove 102 and the mounting surface. Even when the space between the freezer and the wall is small, the combination of the first air inlet 103 and the second air inlet 104 can make the space outside the cabinet 1 enter the compressor chamber 101 more smoothly, thereby maintaining the ventilation in the compressor chamber 101 and avoiding local heat dissipation problems in the compressor chamber 101.

[0068] like Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments, the compressor chamber cover 14 may be provided with an air outlet 105 on one side of the second chamber 1012. The air outlet 105 connects the second chamber 1012 with the outside of the box 1, and the air outlet 105 is located on the side of the support groove 102 away from the first air inlet 103.

[0069] When the fan 22 is started, the air outside the housing 1 can enter the first chamber 1011 through the first air inlet 103, then flow through the condenser 21 and carry away the heat on the surface of the condenser 21 before entering the second chamber 1012, and finally being discharged from the air outlet 105. During this process, the fan 22 can form an airflow in the compressor chamber 101 to efficiently dissipate heat from the condenser 21 and promptly discharge the heat in the compressor chamber 101 to the outside of the housing 1.

[0070] The protrusion 13 formed by the compressor chamber cover 14 cooperates with the fan bracket 23 to define the first chamber 1011 and the second chamber 1012 within the compact compressor chamber 101. This allows the airflow entering the compressor chamber 101 to flow orderly along the first chamber 1011 to the second chamber 1012 and leave the compressor chamber 101 through the air outlet 105. This enables a compact arrangement of the compressor 4 condenser 21 and the fan 22 within the compressor chamber 101, while also improving the heat dissipation effect of the compressor chamber 101 and timely cooling of the condenser 21. This effectively improves the space utilization of the refrigeration unit and increases the usable volume of the product.

[0071] like Figure 4 As shown, in some embodiments, the compressor 4 is located inside the second chamber 1012, and the air outlet 105 can be located on the side of the compressor chamber cover 14 close to the compressor 4. When the fan 22 is started, the airflow in the second chamber 1012 can flow through the compressor 4 and then be discharged through the air outlet 105, thereby improving the heat dissipation effect on the compressor 4.

[0072] like Figure 6 and Figure 7 As shown, in some embodiments, multiple air outlets 105 can be provided, and the multiple air outlets 105 are arranged at intervals on the side of the compressor chamber cover 14 located in the second chamber 1012. The air outlets 105 can be arranged at intervals on the side away from the support groove 102, so that the air outlets 105 are located on the side of the second chamber 1012 away from the first chamber 1011. This helps to extend the airflow path within the second chamber 1012 and further improve the heat dissipation effect within the compressor chamber 101.

[0073] like Figure 4 As shown, in some implementations, the air outlet 105 may be located on the first side wall 12, and the air outlet 105 is located on the side away from the first compartment 1011.

[0074] Figure 8 for Figure 1 Another schematic diagram.

[0075] like Figure 8 As shown, in some embodiments, the housing 1 may have a second sidewall 15, which is located on the other side of the first compartment 1011. The second sidewall 15 is adjacent to the first sidewall 12, and one side of the second sidewall 15 is connected to the first sidewall 12. The second sidewall 15 may be provided with a third air inlet 106, which connects the first compartment 1011 to the outside of the housing 1.

[0076] Because the condenser 21 generates a large amount of heat during operation, and the compressor chamber 101 inside the freezer is relatively small, overheating can easily occur in this confined space. By providing a third air inlet 106 on the second side wall 15, which is located on the other side of the first compartment 1011 and adjacent to the first side wall 12, and placing the third air inlet 106 on a different side from the first air inlet 103 or the second air inlet 104, airflow can enter the first compartment 1011 from different directions. This not only increases the total amount of air entering the first compartment 1011 but also allows air to enter from multiple angles. Providing air inlets 201 on different sides improves the heat dissipation effect within the compressor chamber 101, preventing localized poor heat dissipation in the condenser 21 and improving the overall heat dissipation effect.

[0077] Furthermore, the first air inlet 103, the second air inlet 104, and the third air inlet 106 are respectively connected to the first chamber 1011, which is conducive to the airflow entering the compressor chamber 101 along the first chamber 1011 defined by the fan bracket 23 and the boss 13, thereby increasing the air supply volume and improving the airflow circulation efficiency.

[0078] like Figure 1 and Figure 8 As shown, in some embodiments, the second sidewall 15 can serve as the rear sidewall of the cabinet 1, and the first sidewall 12 can be connected between the rear sidewall and the front sidewall of the cabinet 1. The first compartment 1011 and the second compartment 1012, separated by the fans 22 and the boss 13, can be arranged along the front-rear direction of the freezer, wherein the first compartment 1011 is located behind the second compartment 1012.

[0079] Since the back of the freezer is usually set against the wall, the third air inlet 106 is easily blocked, which affects the heat dissipation effect in the compressor chamber 101. By setting the first air inlet 103 and the second air inlet 104 on the first side wall 12, the air inlets 201 are distributed on different sides of the cabinet 1. In this way, air can enter the compressor chamber 101 from different directions. Even if the second side wall 15 of the freezer is set against the wall, air can still enter the first compartment 1011 through the first air inlet 103 and the second air inlet 104 on the first side wall 12, thereby ensuring the air volume entering the compressor chamber 101.

[0080] like Figure 3 As shown, in some embodiments, the refrigeration device may include a ventilation element 16, which is disposed on the second side wall 15. The ventilation element 16 is recessed towards the first compartment 1011 to form a ventilation groove 107, and the groove wall of the ventilation groove 107 is provided with a third air inlet 106.

[0081] The ventilation component 16 is recessed into the outer wall of the first chamber 1011 to form a ventilation groove 107. The groove wall of the ventilation groove 107 is provided with a third air inlet 106. Compared with directly opening the third air inlet 106 on the second side wall 15, the ventilation groove 107 can form a three-dimensional air channel on the second side wall 15. When the fan 22 is working, the airflow on one side of the second side wall 15 can be orderly gathered and enter the first chamber 101 through the ventilation groove 107, which is conducive to the air entering the compressor chamber 101 more concentratedly and smoothly, thereby efficiently dissipating heat from the condenser 21.

[0082] On the other hand, by providing a third air inlet 106 on the side wall of the ventilation slot 107, the third air inlet 106 can make full use of the three-dimensional space of the ventilation slot 107, which is beneficial to expand the air intake area without increasing the overall size of the housing 1, thereby increasing the amount of air entering the first chamber 1011; furthermore, the third air inlet 106 is set in the support slot 102, which can prevent the air intake of the compressor chamber 101 from being reduced due to the second side wall 15 being blocked by the mounting surface. The setting of the third air inlet 106 can provide more cold air for heat exchange for the condenser 21, and improve the ventilation and heat dissipation performance of the condenser 21 in the compact compressor chamber 101.

[0083] like Figure 3 As shown, in some embodiments, the ventilation component 16 may be provided with a plurality of third air inlets 106, some of which may be provided along the peripheral sidewall of the ventilation component 16, and some of which may be provided along the sidewall of the ventilation component 16 near the condenser 21.

[0084] In some embodiments, the ventilation component 16 may be provided with a corresponding insertion hole, which allows the portion of the power cord extending outside the housing 1 inside the refrigeration device to be stored in the corresponding location, thereby improving the compactness of the overall structure.

[0085] Figure 9 for Figure 4 Installation diagram of the interior of the medium-pressure compressor chamber; Figure 10 for Figure 9 A schematic diagram from another perspective.

[0086] like Figure 4 , Figure 9 and Figure 10 As shown, in some embodiments, the refrigeration device may include a seal 3, which is disposed around the periphery of the fan bracket 23. The seal 3 is used to seal the gap between the fan bracket 23 and the side wall of the compressor chamber 101, which can reduce the airflow directly flowing through the gap between the fan bracket 23 and the side wall of the compressor chamber 101 to the second chamber 1012, so that more airflow passes through the condenser 21.

[0087] In some embodiments, the seal 3 may include a first sealing portion 31, a second sealing portion 32, and a third sealing portion 33 connected in sequence, wherein the first sealing portion 31, the second sealing portion 32, and the third sealing portion 33 may clamp and seal at different positions. The first sealing portion 31, the second sealing portion 32, and the third sealing portion 33 may be separately provided or integrally provided.

[0088] The first sealing part 31 can be clamped between the fan bracket 23 and the boss 13. The first sealing part 31 can seal the gap between the fan bracket 23 and the boss 13, thereby preventing gas from flowing from the connection gap between the fan bracket 23 and the boss 13 to the second chamber 1012.

[0089] The second sealing part 32 is sandwiched between the top wall of the compressor chamber 101 and the top of the fan bracket 23. The second sealing part 32 can seal the gap between the top of the fan bracket 23 and the top wall of the compressor chamber 101, thereby preventing gas from flowing from the connection gap between the top of the fan bracket 23 and the top wall of the compressor chamber 101 to the second chamber 1012.

[0090] The third sealing part 33 is clamped between the side of the fan bracket 23 away from the boss 13 and the side wall of the compressor chamber 101. The third sealing part 33 can seal the gap between the side of the fan bracket 23 away from the boss 13 and the side wall of the compressor chamber 101, thereby preventing gas from flowing from the connection gap between the side of the fan bracket 23 away from the boss 13 and the side wall of the compressor chamber 101 to the second chamber 1012.

[0091] In this embodiment, by respectively setting the first sealing part 31, the second sealing part 32 and the third sealing part 33 to seal against different positions of the fan bracket 23, the airflow can flow more efficiently and orderly along the first chamber 1011 and the second chamber 1012 defined between the fan bracket 23 and the boss 13, which improves the airflow circulation efficiency in the compressor chamber 101. At the same time, it reduces the problem of turbulence and eddies caused by the gas flowing through the gap between the fan bracket 23 and the side wall of the compressor chamber 101, and makes the gas flow in the compressor chamber 101 according to the predetermined channel, reducing the noise during the heat dissipation process.

[0092] like Figure 2 As shown, in some embodiments, the bottom of the fan bracket 23 can directly abut against the bottom wall of the compressor chamber 101, which can improve the connection reliability between the fan bracket 23 and the compressor chamber 101.

[0093] It should be noted that in some other embodiments, the bottom of the fan bracket 23 may also be provided with a fourth sealing part, which can seal against the bottom wall of the compressor chamber 101 and the bottom of the fan bracket 23.

[0094] In some embodiments, the seal 3 may be made of a material with a certain degree of elasticity, such as rubber or silicone. During the operation of the refrigeration unit, components such as the fan 22 and compressor 4 will vibrate, and these vibrations will be transmitted to the fan bracket 23. By using a seal 3 with a certain degree of elasticity wrapped around the periphery of the fan bracket 23, the elasticity of the seal 3 can buffer and absorb vibration energy, prevent vibration from being transmitted to the side wall of the compressor chamber 101, and thus reduce the noise caused by vibration.

[0095] In some embodiments, condenser 21 may be configured as a microchannel condenser 21.

[0096] like Figure 4 , Figure 9 and Figure 10 As shown, in some embodiments, the compressor 4 may be disposed opposite to the fan 22 and located on the side of the fan 22 away from the condenser 21. The refrigeration device may include a first delivery pipe 24, with the inlet end of the condenser 21 located at the top of the condenser 21. The first delivery pipe 24 connects the liquid outlet end of the compressor 4 and the inlet end of the condenser 21, and is used to supply refrigerant from the compressor 4 to the condenser 21.

[0097] The first delivery pipe 24 passes through the top wall of the compressor chamber 101 and onto the fan bracket 23. The first delivery pipe 24 can be located on the outside of the fan bracket 23. The first delivery pipe 24 is distributed at the top of the compressor chamber 101 and connects to the top of the condenser 21 via the outer top of the fan bracket 23. The first delivery pipe 24 is sandwiched between the second sealing part 32 and the fan bracket 23.

[0098] Specifically, the inlet end of the condenser 21 is located at the top of the condenser 21. The refrigerant flowing to the condenser 21 via the compressor 4 can be transported downwards from the top of the condenser 21. Due to gravity, the refrigerant can naturally fill the pipes of the condenser 21, improving the refrigerant transport efficiency and helping to reduce the energy consumption of the refrigeration system. Moreover, by clamping the first delivery pipe 24 between the second sealing part 32 and the fan bracket 23, the second sealing part 32 can seal the gap between the fan bracket 23 and the top wall of the compressor chamber 101, while also sealing the outside of the first delivery pipe 24 located at the top of the fan bracket 23, preventing the installation of the first delivery pipe 24 from affecting the sealing effect between the two sides of the fan bracket 23 and the compressor chamber 101.

[0099] In some embodiments, a first liquid collecting pipe 26 may be provided on the first delivery pipe 24. The first liquid collecting pipe 26 is located at the inlet end of the condenser 21. The first liquid collecting pipe 26 may be sandwiched between the second sealing part 32 and the fan bracket 23, or the first liquid collecting pipe 26 may be located on the inner side of the fan bracket 23.

[0100] In some embodiments, the first delivery pipe 24 may include a bend 241, which is connected to the end of the first liquid collecting pipe 26 away from the condenser 21. The bend 241 is arranged in a curved manner, which can buffer the flow of refrigerant. When the refrigerant flows from the compressor 4 to the condenser 21, its flow rate will be slowed down to a certain extent through the bend 241, which helps to reduce the turbulence and pulsation generated by the refrigerant during the flow. When the refrigeration system is working, the refrigerant can flow stably in the compressor 4 and the condenser 21, thereby improving the operational stability of the refrigeration system.

[0101] like Figure 4 and Figure 9 As shown, in some embodiments, the refrigeration device may include a filter 5 connected to the outlet end of the condenser 21, and the filter 5 is located inside the second compartment 1012. The filter 5 is connected between the outlet end of the condenser 21 and the evaporator, and can filter out moisture or other impurities in the refrigerant flowing out of the condenser 21.

[0102] Since the condenser 21 is installed in the first compartment 1011, the condenser 21 generates a lot of heat during operation. By setting the filter 5 in the second compartment 1012, the impact of the heat generated by the condenser 21 on the filter 5 can be reduced, and the space in the second compartment 1012 can be fully utilized.

[0103] When the fan 22 starts, the airflow in the first compartment 1011 can flow into the second compartment 1012. The airflow in the second compartment 1012 can dissipate heat and cool down the filter 5, which can reduce the temperature of the refrigerant flowing to the evaporator through the filter 5, which is beneficial to improving the heat absorption effect of the evaporator, thereby improving the overall cooling efficiency of the refrigeration system.

[0104] like Figure 9 and Figure 10 As shown, in some embodiments, the refrigeration device may include a second delivery pipe 25, which is connected between the outlet end of the condenser 21 and the filter 5. The second delivery pipe 25 passes through the top wall of the compressor chamber 101 and onto the fan bracket 23. The second delivery pipe 25 is used to supply refrigerant to leave the condenser 21.

[0105] The second conveying pipe 25 can be located on the outside of the fan support 23 and on the side of the fan support 23 away from the first conveying pipe 24. The first conveying pipe 24 and the second conveying pipe 25 can be respectively located on both sides of the top of the compressor chamber 101 and extend into the second chamber 1012 through the top outside of the fan support 23. The second conveying pipe 25 is sandwiched between the second sealing part 32 and the fan support 23.

[0106] Specifically, the outlet end of the condenser 21 is located at the bottom of the condenser 21, and the second delivery pipe 25 can extend upward from the bottom of the condenser 21 and then extend into the second chamber 1012 through the top of the fan bracket 23. By clamping the second delivery pipe 25 between the second sealing part 32 and the fan bracket 23, the second sealing part 32 can seal the gap between the fan bracket 23 and the top wall of the compressor chamber 101, and at the same time, seal the outside of the second delivery pipe 25 located at the top of the fan bracket 23, preventing the installation of the second delivery pipe 25 from affecting the sealing effect between the two sides of the fan bracket 23 and the compressor chamber 101.

[0107] like Figure 9 and Figure 10 As shown, furthermore, both the first conveying pipe 24 and the second conveying pipe 25 are disposed on the top of the fan support 23, which facilitates the formation of a good sealing structure between the two sides of the fan support 23 and the side walls of the compressor chamber 101, making the component distribution within the compressor chamber 101 more compact and reasonable. The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of this application is limited only by the appended claims.
