Description

Technical Field

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

[0002] Refrigeration equipment can be classified into three categories based on its temperature range: general refrigeration equipment, cryogenic refrigeration equipment, and ultra-low temperature refrigeration equipment. General refrigeration equipment is mainly used for common refrigeration needs such as freezing and refrigeration of food, such as freezers or refrigerators. Cryogenic and ultra-low temperature refrigeration equipment are mainly used for the preservation of biological samples, bacterial strains, and pharmaceuticals, such as ultra-low temperature report refrigerators, which have wide applications in the fields of medicine, biological products, and electronic materials.

[0003] Refrigeration equipment includes a cabinet and a refrigeration system housed within it. The cabinet defines a storage compartment, and the refrigeration system provides cooling to this compartment, creating a lower temperature environment for freezing or refrigerating items and extending their shelf life. Existing refrigeration systems generate a significant amount of heat during operation. Typically, heat dissipation inlets and outlets are provided in the equipment cavity, and forced cooling is achieved using a fan to ensure stable operation of the refrigeration system.

[0004] When the condenser module is working for a long time, its windward side is covered with a lot of dust and debris, which blocks the air duct, greatly reduces the heat dissipation efficiency of the condenser module, and increases energy consumption accordingly.

[0005] To address this technical issue, related technologies typically involve vertically installing a filter screen inside the heat dissipation air inlet to prevent dust and debris from entering the equipment cavity and directly contacting the condenser module. However, this vertically installed filter screen allows filtered dust to easily accumulate, causing mesh blockage and affecting the ventilation and heat dissipation of the refrigeration system. Furthermore, the frequent accumulation of dust and clogging of the mesh requires users of ultra-low temperature freezers to frequently clean and replace the filter screen, impacting the user experience.

[0006] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore,

[0007] According to embodiments of this disclosure, a refrigeration device is provided, comprising:

[0008] The container has a defined storage compartment for placing items.

[0009] The equipment cavity is formed inside the box, and the box is provided with a heat dissipation air inlet and a heat dissipation air outlet that communicate with the equipment cavity;

[0010] A refrigeration system for providing cooling to the storage compartment, the refrigeration system including a condenser module located inside the equipment cavity;

[0011] An air intake channel connects the heat dissipation air intake port to the air intake side of the condenser module;

[0012] A filter structure is installed in the air inlet channel, and the filter structure includes:

[0013] Two guide rails are respectively set on the two side walls of the air inlet channel, which are opposite to each other. The guide rails are inclined from top to bottom in the direction away from the heat dissipation air inlet.

[0014] The filter screen has its two opposite ends inserted into the two guide rails so that the filter screen is inclined inside the heat dissipation air inlet, wherein the windward end of the filter screen is higher than the leeward end of the filter screen.

[0015] In this technical solution, the inclined guide rail allows the filter to be installed tilted and detachably inside the heat dissipation air inlet, changing the traditional method of vertically installing the filter. This allows dust to fall below the filter due to the reaction force of the filter and the gravity of the dust itself, reducing dust accumulation on the filter, lowering the frequency of filter clogging and cleaning, and enabling it to better perform its ventilation, heat dissipation, and dust prevention functions. This improves the stability of the refrigeration system and enhances the user experience.

[0020] According to embodiments of this disclosure, the filter structure may include two baffles, and two guide rails are respectively formed on the sides of the two baffles facing each other. The two guide rails are respectively mounted on the opposite side walls of the air inlet channel through the two baffles.

[0021] In this technical solution, the baffle allows air to enter the refrigeration system more concentratedly, reducing the waste of air volume and improving the ventilation and heat dissipation efficiency of the refrigeration system.

[0022] According to an embodiment of this disclosure, the baffle is in the shape of a right triangle, and the guide rail is disposed near the hypotenuse of the baffle.

[0023] In this technical solution, the structural design of the baffle makes the tilt angle of the filter screen more reasonable, which can better guide the airflow and provide a smoother channel for dust to fall, further reducing the accumulation of dust on the filter screen.

[0024] According to an embodiment of this disclosure, the inclined side of the baffle forms a flange that bends toward the opposite side of the baffle, and a limiting portion is provided on the mutually facing sides of the two baffles, with the limiting portion and the flange forming the guide rail.

[0025] In this technical solution, the guide rail is formed by the combined use of the flange and the limiting part, which not only increases the strength and stability of the baffle, but also makes the structure of the guide rail more robust and reliable, and can better support and limit the filter screen, ensuring the stable installation and use of the filter screen.

[0026] According to embodiments of this disclosure, the limiting portion is welded or screwed onto the baffle.

[0027] In this technical solution, the welding or screw connection method is firm and reliable, which can ensure the stability and reliability of the guide rail and improve the service life and stability of the entire filter structure.

[0028] According to an embodiment of this disclosure, the top end of the filter screen is located at the heat dissipation air inlet, and the bottom end of the filter screen abuts against the bottom wall of the device cavity.

[0029] According to an embodiment of this disclosure, the refrigeration equipment further includes an air inlet shroud, which is connected to the housing to cover the heat dissipation air inlet, and the air inlet shroud is provided with a plurality of through holes.

[0030] In this technical solution, by setting up an air inlet hood to perform preliminary filtration of the airflow entering the equipment cavity, the aesthetics of the enclosure can be improved.

[0031] According to an embodiment of this disclosure, the air inlet shroud protrudes in a direction away from the device cavity relative to the heat dissipation air inlet, and the top of the air inlet shroud has an installation port for installing the filter screen;

[0032] The filter screen has a handle at its top, which covers the mounting port.

[0033] In this technical solution, the installation port and handheld part facilitate the installation of the filter screen. At the same time, the handheld part covers the installation port, which not only ensures the air filtration effect but also improves the appearance.

[0034] According to embodiments of this disclosure, the condenser module includes:

[0035] A housing is installed inside the equipment cavity. The housing has an air inlet side and an air outlet side, and the air inlet side is connected to the air inlet channel.

[0036] The condenser body is installed inside the housing;

[0037] A condenser fan is located on the air outlet side.

[0038] In this technical solution, by placing the filter structure on the air inlet side of the condenser module, the filter screen can better protect key components such as the condenser module, prevent dust and other impurities from entering, and improve the stability and service life of the refrigeration system.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0062] This utility model proposes a refrigeration device, which relates to the field of refrigeration equipment technology, and improves the ventilation and heat dissipation effect of the refrigeration system.

[0063] The following is for reference. Figures 1-15 Describe the refrigeration equipment.

[0064] Please refer to Figure 1 In one illustrative embodiment of the refrigeration equipment of this utility model, the refrigeration equipment may include a housing and a refrigeration system disposed inside the housing.

[0065] The refrigeration equipment can include freezers, refrigerators, and ultra-low temperature freezers.

[0066] The interior of the cabinet 20 is defined by a storage compartment, which is used to store items that require low-temperature refrigeration or freezing. When the refrigeration equipment is an ultra-low temperature freezer, the items in the storage compartment can be biological samples, bacterial strains, drugs, etc.

[0067] The refrigeration system provides cooling for the storage room. In other words, it cools the interior environment of the storage room. This provides a stable low-temperature environment for the stored items, meeting the user's storage needs for different items.

[0068] The cabinet has an equipment cavity 30 inside, which is located below the storage room and provides installation and heat dissipation space.

[0069] refer to Figure 1 , Figure 7 as well as Figure 15The housing 20 is provided with a heat dissipation air inlet 40 and a heat dissipation air outlet 50 that communicate with the equipment cavity 30. The design of the heat dissipation air inlet 40 and the heat dissipation air outlet 50 ensures that air can flow smoothly through the equipment cavity 30, thereby effectively removing the heat generated during the operation of the refrigeration system.

[0070] In some embodiments, reference Figure 7 The heat dissipation air inlet 40 and the heat dissipation air outlet 50 can be located on the same side wall of the enclosure.

[0071] Of course, in some other embodiments, references Figure 15 The heat dissipation air inlet 40 and the heat dissipation air outlet 50 can be set on the opposite side walls of the enclosure.

[0072] This application does not restrict the relative positions of the heat dissipation air inlet 40 and the heat dissipation air outlet 50.

[0073] In this embodiment, at least part of the refrigeration system is located inside the equipment cavity 30, so that the refrigeration system can directly contact the air inside the equipment cavity 30, thereby more effectively dissipating the heat generated during operation.

[0074] Specifically, the refrigeration system may include a condenser module 60 located inside the equipment cavity. The refrigeration principle of the refrigeration system is well known to those skilled in the art and will not be described in detail here.

[0075] Further reference Figure 3 , Figure 7 The refrigeration equipment may include an air inlet channel 70, which connects the heat dissipation air inlet to the air inlet side of the condenser module 60.

[0076] In other words, the air inlet side of the condenser module 60 is connected to the heat dissipation air inlet 40, ensuring that air can smoothly enter the condenser module 60 from the heat dissipation air inlet 40.

[0077] The air intake channel 70 can effectively guide the airflow, so that the airflow at the heat dissipation air intake 40 flows more concentratedly to the cooling system through the air intake channel 70.

[0078] In this embodiment, by setting the air inlet channel 70 to limit the airflow path, the loss and resistance of airflow before entering the refrigeration system are reduced, the waste of air volume is reduced, and the ventilation and heat dissipation efficiency of the refrigeration system is improved.

[0079] The refrigeration equipment may include a filter structure 10, which is installed in the air inlet channel 70 inside the heat dissipation air inlet 40.

[0080] In other words, the filter structure 10 is located between the heat dissipation air inlet 40 and the condenser module 60, which can filter the air entering the equipment cavity 30, effectively remove dust, impurities and other contaminants from the air, and protect the refrigeration system from dust contamination.

[0081] In some embodiments of this application, the filter structure 10 may include two guide rails 3 and a filter 2 mounted on the two guide rails 3.

[0082] Two guide rails 3 are respectively set on the opposite side walls of the air inlet channel 70. The guide rails 3 provide the mounting base for the filter screen 2, and are used to install and limit the filter screen 2, ensuring that the filter screen 2 can be firmly installed and fixed inside the heat dissipation air inlet 40.

[0083] The guide rail 3 is tilted from top to bottom in a direction away from the heat dissipation air inlet, which allows the filter screen 2 to be installed at an angle inside the heat dissipation air inlet 40.

[0084] refer to Figure 9 The two ends of the filter screen 2 are inserted into two guide rails 3 so that the filter screen 2 is tilted inside the heat dissipation air inlet 40.

[0085] By inserting both ends of the filter screen 2 into the guide rail 3, the filter screen 2 can be quickly installed and removed. This plug-in design allows users to easily clean and replace the filter screen 2, improving maintenance convenience, reducing maintenance time and labor intensity, and thus enhancing the user experience.

[0086] In this embodiment, the filter screen 2 can be installed at an angle inside the heat dissipation air inlet 40 via the guide rail 3, which changes the traditional method of vertically installing the filter screen, ensuring that the filtration function of the filter screen 2 can be performed stably and reliably, and providing continuous ventilation and dust protection for the refrigeration system.

[0087] refer to Figure 3 , Figure 4 , Figure 6 The windward end of filter 2 is higher than the leeward end of filter 2, and the plane where filter 2 and the heat dissipation air inlet 40 are located forms an acute angle with the opening facing downward. This arrangement allows filter 2 to better perform its functions of ventilation, heat dissipation, and dust prevention, while providing a smoother channel for dust to fall, further reducing dust accumulation on the filter and improving the stability and service life of the refrigeration system.

[0088] Specifically, when dust comes into contact with filter 2, it can naturally fall to the bottom of filter 2 due to the reaction force of filter 2 and the gravity of the dust itself. This reduces the accumulation of dust on filter 2, reduces the clogging of filter 2 and the frequency of cleaning. This not only improves the service life and ventilation effect of filter 2, but also improves the ventilation and heat dissipation performance of the refrigeration system, thus enhancing the user experience.

[0089] In some embodiments of this application, the filter 2 includes a filter frame 21 and a filter body 22.

[0090] refer to Figure 10 The filter frame 21 is grid-shaped and has through holes, and the filter body 22 is connected to the filter frame 21 and covers the through holes.

[0091] In this embodiment, the above-mentioned structure of the filter screen 2 not only ensures ventilation, allowing air to pass smoothly through the filter screen 2 and be blown into the refrigeration system, but also the filter screen body can effectively filter dust, impurities, etc. in the air, preventing these impurities from adhering to various components of the refrigeration system, thereby protecting the normal operation of the refrigeration system and extending its service life.

[0092] In some embodiments of this application, reference is made to Figure 10 A handle 4 is provided at the top of the filter screen 2.

[0093] The handle 4 provides a convenient operating point for users, making it easy for them to take, clean and replace the filter screen 2.

[0094] The handle 4 is located at the top of the filter screen 2, making it easier for users to grasp the filter screen 2 during operation, reducing the difficulty and inconvenience of operation, and further improving the user experience.

[0095] refer to Figure 7 , Figure 8 The top of the filter screen 2 is located at the heat dissipation air inlet 40, and the bottom of the filter screen 2 abuts against the bottom wall of the equipment cavity 30.

[0096] In some embodiments of this application, reference is made to Figure 11 The filter structure 10 may include two baffles 1 and two guide rails 3 formed on the sides of the two baffles 1 facing each other.

[0097] Two guide rails 3 are respectively installed on the opposite side walls of the air inlet channel 70 via two baffles 1. The two baffles 1 are symmetrically arranged in the vertical direction.

[0098] refer to Figure 12 , Figure 13 In some embodiments, the baffle 1 is a right triangle, and the guide rail 3 is positioned near the hypotenuse of the baffle 1.

[0099] The right-angled triangular baffle 1 has a simple and stable structure and can make full use of space.

[0100] The guide rail 3 can be set parallel to the inclined side of the baffle 1.

[0101] In this embodiment, the guide rail 3 is positioned close to the inclined side of the baffle 1, and the guide rail 3 is parallel to the inclined side of the baffle 1. This not only better supports the filter screen 2, but also allows the filtered airflow to enter the refrigeration system more smoothly and in a concentrated manner, preventing dust in the airflow before filtration from adhering to the baffle 1.

[0102] Of course, in some other embodiments, the baffle 1 can be rectangular or other shapes, as long as the guide rail 3 can make the filter screen 2 tilted relative to the heat dissipation air inlet 40.

[0103] Continue to refer to Figure 13 The inclined side of the baffle 1 forms a flange 31 that bends toward the opposite side of the baffle 1. A limiting part 32 is provided on the mutually facing sides of the two baffles 1, and a guide rail 3 is formed between the limiting part 32 and the flange 31.

[0104] In this embodiment, the flange 31 further enhances the structural strength and stability of the baffle 1. By setting the guide rail 3, which is jointly defined by the limiting part 32 and the flange 31, it can more firmly support the filter screen 2, ensuring the stability and reliability of the filter screen 2 during use.

[0105] The limiting part 32 can be welded or screwed onto the baffle 1.

[0106] The welding or screw connection method makes the connection between the limiting part 32 and the baffle 1 firm and reliable, ensuring the stability and reliability of the guide rail 3, effectively preventing problems such as unstable installation or falling off of the filter screen 2 due to loose connection, thereby ensuring the normal operation of the refrigeration system and the ventilation and heat dissipation effect.

[0107] In some embodiments, the refrigeration equipment may include an air inlet shroud 90, which is connected to the housing to cover the heat dissipation air inlet 40, and the air inlet shroud 90 is provided with a plurality of through holes.

[0108] refer to Figure 1 , Figure 5 An air inlet shroud 90 is installed at the heat dissipation air inlet 40, which can guide external air into the equipment cavity 30. By setting the air inlet shroud 90 to perform preliminary filtration of the airflow entering the equipment cavity, the aesthetics of the enclosure can also be improved.

[0109] It is understandable that the air inlet shroud 90 is located outside the heat dissipation air inlet 40 or at the end away from the equipment cavity 30.

[0110] In this embodiment, the filter screen 2 is inclined, which creates a buffer space between the air inlet hood 90 and the filter structure 10. This allows the air entering through the through holes on the air inlet hood 90 to have a buffer zone before passing through the filter screen 2 and entering the refrigeration system for ventilation and heat dissipation. This allows the filter screen 2 to better perform its functions of ventilation, heat dissipation, and dust prevention.

[0111] refer to Figure 6 In some embodiments of this application, the air inlet shroud 90 protrudes relative to the heat dissipation air inlet 40 in a direction away from the equipment cavity 30, and the top of the air inlet shroud 90 is provided with an installation port 901 for installing the filter screen 2.

[0112] In this embodiment, the filter screen 2 can be inserted into the guide rail 3 through the mounting port 901, or the filter screen 2 can be removed through the mounting port 901 to complete the installation and removal of the filter screen 2, which facilitates the replacement and cleaning of the filter screen 2.

[0113] Further reference Figure 6 The filter screen has a handle 5 at the top, which makes it easy for users to pick up and place the filter screen 2, making the cleaning and replacement of the filter screen 2 more convenient and quick, and effectively improving the user experience.

[0114] Furthermore, after the filter 2 is installed, the handheld part 5 covers the installation port 901, which not only ensures the air filtration effect but also improves the appearance.

[0115] In some embodiments of this application, reference is made to Figure 8 The condenser module 60 may include a housing 61, a condenser fan 63, and a condenser body 62 installed in the housing 61.

[0116] The condenser body 62 includes fins and several condenser tubes, which will not be described in detail here.

[0117] The housing 61 has an air inlet side and an air outlet side. In some embodiments, reference... Figure 8 The air intake side can be directly opposite the heat dissipation air intake 40. The heat dissipation air intake 40 can also be located on one side of the air intake side. The air intake side is connected to the air intake channel 70, and the air outlet side is equipped with a condenser fan 63.

[0118] The air inlet side of the housing 61 is connected to the air inlet channel 70, ensuring that air can smoothly enter the condenser module 60. The air outlet side of the housing is equipped with a condenser fan 63, which can quickly dissipate the heat emitted by the condenser module 60, ensuring the stability and reliability of the condenser module 60 during long-term operation and extending the service life of the condenser module 60.

[0119] The refrigeration system may include a compressor 80. The compressor 80 is located on the side of the condenser fan 63 away from the condenser module 60. The condenser fan 63 is located on the air outlet side of the condenser module 60. The airflow formed by the condenser fan 63 flows between the equipment cavity 30 and the external environment, thereby carrying away the heat generated by the condenser module 60 and the compressor 80.

[0120] In some embodiments, when the refrigeration equipment is an ultra-low temperature freezer, the compressor 80 may include a primary compressor 80 and a secondary compressor 80.

[0121] refer to Figures 1-4 Taking an ultra-low temperature freezer as an example, the cabinet can be configured in two parts, including an insulation shell 201 and a base 202, with the base 202 connected to the bottom of the insulation shell 201. The insulation shell 201 defines a storage compartment, and the base 202 defines an equipment cavity 30. A heat dissipation air inlet 40 and a heat dissipation air outlet 50 are formed on the side wall of the base 202.

[0122] refer to Figure 14 , Figure 15 The base 202 may include a support frame 2021, which forms the main body of the base 202. The condenser module 6 may be mounted on the support frame 2021.

[0123] The support frame 2021 includes two connecting ribs 2025 located on the windward side of the condenser module 60, and two baffles 1 are respectively connected to the two connecting ribs 2025.

[0124] For details, please refer to Figure 15 The base 202 may include a base plate 2022 disposed at the bottom of the support frame 2021, and the base 202 provides an installation position for part of the refrigeration system.

[0125] The base 202 may include side plates 2023 disposed on the left and right sides of the support frame 2021 and a front cover 2024 disposed on the front side of the support frame 2021. The heat dissipation air inlet 40 is opened on the front cover 2024, and the air inlet shroud is connected to the front cover 2024.

[0126] The base plate 2022 and the side walls on the left and right sides form a heat dissipation vent 50 located on the rear side of the base 202.

[0127] In this embodiment, the two baffles 1 are respectively connected to the connecting ribs 2025, which not only ensures the installation stability of the condenser module 60 and the baffles 1, but also optimizes the spatial layout within the equipment cavity 30, improving the structural compactness and stability of the entire refrigeration system. The support frame 2021 provides a stable support structure for the baffles 1.

[0128] Of course, in some other embodiments, such as when the refrigeration equipment is a horizontal refrigerator or freezer, the cabinet can be set up as one piece.

[0129] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0130] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
