Description

Technical Field

[0001] This utility model relates to the technical field of refrigerators, and in particular to a novel bottom heat dissipation structure for refrigerators. Background Technology

[0002] A refrigerator is a household appliance that uses a refrigeration system to lower the internal temperature to preserve food, medicine and other items for a long time. It is widely used in homes, businesses and medical settings. Its core function is to use a compressor to drive the refrigerant to transfer heat in thermodynamic cycles such as condensation and evaporation, thereby maintaining a low-temperature environment inside the refrigerator.

[0003] During refrigerator operation, the bottom is the main area for heat generation and dissipation. Core refrigeration components such as the compressor and condenser are usually integrated in the bottom space. When the compressor is working, it generates a lot of heat due to mechanical operation and refrigerant compression. The condenser releases the heat in the refrigerant through heat exchange. If the heat at the bottom cannot be dissipated in time, it will cause the components to operate at excessively high temperatures, reduce refrigeration efficiency, increase energy consumption, and even shorten the service life of the equipment.

[0004] However, some traditional refrigerators use a left-right air intake and exhaust design for bottom cooling, requiring deflectors to control the airflow direction. However, the combination of axial fans and fins requires a large placement space and is mostly suitable for refrigerators with wide platforms. In addition, the compressor mounting plate is not compatible with the side cooling solution, which increases manufacturing costs. Furthermore, traditional axial fans have low air pressure and occupy a lot of space, making them difficult to place in the narrow compressor compartment and unsuitable for refrigerators with narrow platforms. Moreover, because the bottom is close to the ground and the ventilation structure is exposed, it is easy for dust to accumulate and insects to be attracted, which not only affects the heat dissipation efficiency but also increases the risk of component contamination and damage. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems existing in the current novel bottom heat dissipation structure of refrigerator, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a novel bottom heat dissipation structure for refrigerators. This structure aims to solve the problems that "most traditional refrigerators use a left and right air intake and exhaust design for bottom heat dissipation in the compressor compartment, which requires a baffle to control the airflow direction. However, the combination of axial flow fans and fins requires a large placement space and is mostly suitable for refrigerators with a wide platform. At the same time, the compressor mounting plate is not compatible with the side cooling solution, which increases manufacturing costs. In addition, the traditional axial flow fans have low air pressure and occupy a lot of space, making it difficult to place them in a small compressor compartment. They are not suitable for refrigerators with a small platform. Furthermore, because the bottom is close to the ground and the ventilation structure is exposed, it is easy to accumulate dust and attract insects, which affects heat dissipation efficiency and increases the risk of component contamination and damage."

[0037] Example 1

[0038] Reference Figures 1 to 5 This is the first embodiment of the present utility model, which provides the following achievable effects:

[0039] Partitioning unit 200, partitioning unit 200 is disposed on refrigerator body 100, partitioning unit 200 is used for component distribution, heat dissipation assembly 300, heat dissipation assembly 300 is disposed on partitioning unit 200, heat dissipation assembly 300 is used for heat dissipation of components.

[0040] Ventilation component 400 and positioning component 500 are both installed on the refrigerator body 100. Ventilation component 400 and positioning component 500 are used for ventilation protection of partition unit 200 and for disassembly and assembly of ventilation component 400, respectively.

[0041] In use, the partition unit 200 rationally distributes the components and, together with the front and rear direct air intake and exhaust settings of the heat dissipation component 300, can adapt to the heat dissipation needs of small platform widths and the bottom of air-cooled refrigerators. This avoids the accumulation of heat at the bottom of the refrigerator due to the large space occupied by the components and their close spacing, which would affect the use of the refrigerator. It also eliminates the need for additional air deflectors. The ventilation component 400 provides ventilation and protection for the components inside the partition unit 200, reducing the risk of dust, foreign objects intrusion, and external damage. At the same time, the positioning component 500 enables quick positioning of the ventilation component 400, reducing the difficulty of disassembly and assembly for daily maintenance and repair, and effectively extending the service life of the components.

[0042] Example 2

[0043] Reference Figures 1 to 5 This is the second embodiment of the present invention, which differs from the previous embodiment in that:

[0044] The partition unit 200 includes a compression chamber 201, which is fixedly connected to the bottom surface of the refrigerator body 100. A water collection box 202 is fixedly connected to the compression chamber 201, which is located in the rightmost area of ​​the compression chamber 201. A condenser 203 and a centrifugal fan 204 are fixedly connected to the water collection box 202, and the condenser 203 and the centrifugal fan 204 are arranged in a front-to-back parallel arrangement. A compressor 205 is fixedly connected to the compression chamber 201, which is located in the leftmost area of ​​the compression chamber 201.

[0045] An independent working space is formed at the bottom of the refrigerator body 100 through the compression chamber 201. The condenser 203 and the centrifugal fan 204 are arranged side by side in the water collection box 202 area on the right, creating an efficient air duct to improve heat dissipation efficiency. The compressor 205 is placed independently in the left area, realizing the physical separation of heat dissipation components and power components, avoiding mutual heat interference. The partition setting optimizes space utilization, ensures orderly operation of each component, and reduces the risk of failure. The centrifugal fan 204 is used for the whole, and its air pressure is high. It is placed on the far right of the water collection box 202 with the condenser 203, arranged in front and behind. The fixed structure of the centrifugal fan 204 is equipped with air guides to realize direct air intake and exhaust for heat dissipation, so that there is no need for air deflectors to guide the airflow. The refrigerator body 100 is specifically the bottom area structure of the refrigerator, which is existing technology and will not be described in detail in this article.

[0046] Specifically, the heat dissipation component 300 includes an air outlet duct 301, which is fixedly connected to the centrifugal fan 204 and the compression chamber 201. The air outlet duct 301 is obliquely arranged.

[0047] The exhaust duct 301 is directly connected to the centrifugal fan 204 to ensure efficient exhaust of heat dissipation airflow. The angled duct structure avoids direct contact with the ground, reducing the interference of ground dust on the exhaust airflow. At the same time, it optimizes the airflow exhaust direction, reducing the risk of hot air accumulating at the bottom. Furthermore, the fixed connection between the exhaust duct 301 and the compression chamber 201 enhances stability. Together with the centrifugal fan 204, it forms a directional airflow channel, significantly improving heat dissipation efficiency.

[0048] Specifically, the ventilation assembly 400 includes two support blocks 401, both of which are fixedly connected to one side surface of the refrigerator body 100. A back plate 402 is movably disposed in both support blocks 401, and multiple air inlets 403 are provided on the back plate 402.

[0049] The backplate 402 is stably supported by two support blocks 401. The movable connection structure facilitates the quick disassembly and assembly of the backplate 402, improving maintenance convenience. The backplate 402 can effectively shield the internal components of the compression chamber 201, reducing the intrusion of dust and foreign objects. Multiple air inlets 403 ensure the smooth flow of air required for heat dissipation, forming a reasonable air intake path to facilitate protection and ventilation needs.

[0050] Specifically, the positioning component 500 includes a bracket 501, which is fixedly connected to one side surface of the refrigerator body 100. A top rod 502 is slidably connected to the bracket 501. One end of the top rod 502 is fixedly connected to an insertion rod 503. An insertion hole 504 is provided on the back plate 402, which is inserted into the insertion rod 503. A round block 505 is fixedly connected to the other end of the top rod 502. A spring 506 is sleeved on the arm of the top rod 502.

[0051] In use, the back panel 402 is fixed to one side of the refrigerator body 100 by the bracket 501. The top rod 502 and the plug rod 503 are connected and engaged. The spring force of the spring 506 is used to achieve a stable positioning of the back panel 402, preventing the back panel 402 from loosening or shifting during protection. When it is necessary to remove the back panel 402, the plug rod 503 can be driven to disengage from the plug hole 504 by pulling the round block 505 to one side, which can quickly release the fixation of the back panel 402. The operation is convenient and labor-saving.

[0052] Example 3

[0053] Reference Figures 1 to 5 This is the third embodiment of the present invention, which differs from the previous embodiment in that:

[0054] A shield 2011 is fixedly connected to the compression chamber 201, and the shield 2011 is fixedly connected to the inner wall of the refrigerator body 100.

[0055] The shield 2011 is fixed to the compression chamber 201 and connected to the inner wall of the refrigerator body 100. It can effectively shield the internal components of the compression chamber 201, reduce the amount of condensation or debris falling into the refrigerator body 100, guide the airflow, optimize the integrity of the heat dissipation duct, and enhance the stability of the internal structure.

[0056] Specifically, the back panel 402 is matched with the refrigerator body 100, and an insect repellent box 4021 is fixedly connected to the back panel 402, and an insect repellent drug is placed inside the insect repellent box 4021.

[0057] The insect repellent box 4021 fixed on the back panel 402 contains insect repellent, which can form an insect-proof barrier in the air intake area to prevent insects from entering the compression chamber 201 through the air intake 403. This does not affect the protective function of the back panel 402, and achieves long-term insect prevention through natural evaporation, thereby improving the safety of equipment operation.

[0058] Specifically, the condenser 203 and the centrifugal fan 204 are arranged parallel to the depth direction of the refrigerator body 100, forming a front-to-back air duct.

[0059] The condenser 203 and the centrifugal fan 204 are arranged along the depth of the refrigerator body 100 to form a front and rear through air duct. This optimizes the airflow path length and direction, allowing for full heat exchange when air flows through the condenser 203. The centrifugal fan 204 efficiently discharges hot air, reducing airflow resistance. The improved air duct connectivity enhances heat dissipation efficiency and ensures uniform heat dissipation of components.

[0060] Specifically, the two ends of the spring 506 are fixedly connected to the bracket 501 and the insertion rod 503, respectively.

[0061] The spring 506 fixes the bracket 501 and the insertion rod 503 at both ends respectively. It continuously applies a pushing force with the help of elastic potential energy to ensure that the insertion rod 503 is stably inserted into the insertion hole 504 and prevent the back plate 402 from loosening. After pulling to unlock, the spring 506 automatically resets and drives the insertion rod 503 to return to its position, realizing quick fixation. The elastic connection structure simplifies the disassembly and assembly operation, eliminates the need for manual alignment, ensures the long-term reliable operation of the positioning component 500, and improves the convenience of use.

[0062] Example 4

[0063] Reference Figures 1 to 5 This is the fourth embodiment of the present invention, which differs from the previous embodiment in that:

[0064] During operation, the compressor 205 in the left area generates heat, while the condenser 203 on the water collection box 202 in the right area simultaneously starts to dissipate heat. The two are physically separated by the partitioned layout within the compression chamber 201 to prevent heat accumulation. At this time, the centrifugal fan 204, running parallel to the condenser 203, starts, forming a directional airflow circulation through the front and rear ventilation ducts parallel to the depth of the refrigerator body 100. This allows outside air to enter the compression chamber 201 through the air inlet 403 on the back panel 402, first flowing through the condenser 203 to complete heat exchange, and then being driven by the centrifugal fan 204 to the outlet duct 301. The obliquely positioned outlet duct 301 adopts a tapered cross-section structure, enhancing airflow speed through the narrowing channel, efficiently expelling the dissipated hot air outside the refrigerator body 100, preventing heat accumulation at the bottom. Simultaneously, the back panel 402 is stably supported by the side supports 401. On the side of the refrigerator body 100, the insect repellent box 4021 fixed on one side uses the volatile components of the built-in insect repellent to diffuse through the ventilation structure to the air intake path and the periphery of the compression chamber 201, forming an insect barrier to prevent insects from entering through the air intake 403 or the gaps between components. The shield 2011 on the compression chamber 201 is fixed to the inner wall of the refrigerator body 100, further guiding the airflow and shielding the internal components. When internal maintenance is required, the round block 505 is pulled to one side, causing the top rod 502 to drive the insertion rod 503 to compress the spring 506, disengaging the insertion rod 503 from the insertion hole 504 on the back plate 402. The back plate 402 can then be slid off along the support block 401 for easy replacement of insect repellent and maintenance of components such as the condenser 203 and centrifugal fan 204. During installation, only the reverse operation is required. The elastic force of the spring 506 pushes the insertion rod 503 back into the insertion hole 504, achieving quick positioning and fixation of the back plate 402.

[0065] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
