[0002] Refrigerators operate relatively smoothly under normal low power consumption conditions. However, in real-world scenarios, it is common to store a large amount of food in the refrigerator within a short period of time. This causes the compressor to run continuously, raising the condenser temperature and requiring further improvement in heat dissipation.

[0003] The heat dissipation problem of condensers has also become an urgent issue that needs to be addressed in the industry. Utility Model Content

[0004] The purpose of this invention is to provide a refrigerator condenser heat dissipation structure and a refrigerator, so as to solve the problem that the heat dissipation effect of the condenser in the prior art needs to be improved.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This utility model first provides a refrigerator condenser heat dissipation structure, which is installed in the compressor compartment of the refrigerator and arranged close to the condenser, including:

[0007] A water storage tray is used to fix the condenser and store the defrost water in the refrigerator.

[0008] A water spray cooling device is fixed on the water storage pan and is used to spray the defrosting water in the water storage pan onto the condenser.

[0009] Furthermore, it also includes: a partition plate, fixed inside the water storage pan, for dividing the water storage pan into an upper water storage section and a lower water storage section that are interconnected; the water inlet end of the water spray cooling device is placed inside the lower water storage section.

[0010] Furthermore, the water spray cooling device includes a water pipe and a water pump, the water pump is installed on the water pipe, the water inlet of the water pipe faces the bottom wall of the water storage pan, and the water outlet of the water pipe faces the condenser.

[0011] Furthermore, a rotatable spray head is installed at the outlet end of the water pipe.

[0012] Furthermore, the water spray cooling device is configured as a plurality of devices, which are fixed at intervals in the water storage pan and located around the condenser.

[0013] Furthermore, a valve for adjusting the water flow is installed at the outlet end of the water pipe.

[0014] Furthermore, the partition plate is fixedly connected to one end of the condenser placed inside the water storage pan, and a gap is left between the partition plate and the side wall of the water storage pan so that the upper water storage part and the lower water storage part can communicate with each other.

[0015] Furthermore, a fan is fixed on the water storage pan, and the fan and the water spray cooling device are located on opposite sides of the condenser.

[0041] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0042] Refrigerators operate relatively smoothly under normal low power consumption conditions. However, in real-world scenarios, it is common to store a large amount of food in the refrigerator within a short period of time. This causes the compressor to run continuously, raising the condenser temperature and requiring further improvement in heat dissipation.

[0043] The heat dissipation problem of condensers has also become an urgent issue that needs to be addressed in the industry.

[0044] In the existing technology, the heat dissipation of the built-in condenser of the refrigerator is generally achieved by the condenser pipe arranged in the foam layer of the refrigerator and dissipating heat through the back panel of the refrigerator, while the heat dissipation of the external condenser of the refrigerator is generally achieved by the condenser arranged next to the compressor and dissipating heat through forced convection by the fan.

[0045] Based on this, the present invention makes full use of defrosting water to cool the condenser, thereby improving the heat dissipation effect of the external condenser of the refrigerator and increasing the refrigeration efficiency.

[0046] Please refer to the following: Figure 1 This utility model proposes a refrigerator condenser heat dissipation structure, which is installed in the compressor compartment of the refrigerator and arranged close to the condenser 3.

[0047] Specifically, the condenser heat dissipation structure of this refrigerator includes:

[0048] Water storage tray 5 is used to fix the condenser 3 and store defrost water in the refrigerator;

[0049] The water spray cooling device 7 is fixed on the water storage pan 5 and is used to spray the defrosting water in the water storage pan 5 onto the condenser 3.

[0050] The advantage of this design is that it includes a water storage tray 5 and a water spray cooling device 7. The water storage tray 5 stores defrost water, and the condenser 3 is fixed inside the tray, allowing the defrost water in the tray to submerge part of the pipes in the condenser 3, thus achieving cooling to a certain extent. The water spray cooling device 7 sprays the defrost water from the tray 5 onto the condenser 3, further enhancing its cooling effect. The portion of the defrost water that evaporates directly carries away more heat through evaporation, while the portion that doesn't evaporate drips back into the tray 5, creating a circulation and effectively reducing water loss. Therefore, this invention fully utilizes defrost water, improving the heat dissipation of the condenser 3 inside the refrigerator and increasing cooling efficiency.

[0051] It should be noted that the water reservoir 5 is fixedly connected to the drain pipe 8, through which the defrost water inside the refrigerator is drained into the water reservoir 5. The defrost water in the refrigerator comes from the frost layer that melts during the defrosting process of the evaporator. Usually, a drip tray is installed below the evaporator to collect the defrost water. The water reservoir 5 and the drip tray are connected to each other through the drain pipe 8, so that the water reservoir 5 can be used to store excess defrost water.

[0052] like Figure 2 As shown, the condenser heat dissipation structure of this refrigerator also includes: a partition plate 6, fixed inside the water storage pan 5, used to divide the water storage pan 5 into an upper water storage section 51 and a lower water storage section 52 that are interconnected; the water inlet of the water spray cooling device 7 is placed inside the lower water storage section 52.

[0053] The advantage of this design is that the present invention can also be equipped with a partition plate 6, which divides the entire water storage space of the water storage pan 5 into upper and lower parts, namely the upper water storage part 51 and the lower water storage part 52. It should be noted that the lower water storage part 52 is not a closed space, and the lower water storage part 52 is connected to the upper water storage part 51, ensuring that defrosting water can flow between the upper water storage part 51 and the lower water storage part 52. Since the defrosting water in the water storage pan 5 can evaporate by absorbing heat from the compressor compartment, the partition plate 6 can reduce the contact area between the defrosting water below it and the outside air, thereby reducing the evaporation of the defrosting water in the lower water storage part 52 and preventing the defrosting water in the water storage pan 5 from completely evaporating. This ensures that the water spray cooling device 7 can spray relatively low-temperature defrosting water onto the condenser 3 when the temperature of the condenser 3 is too high, making full use of the defrosting water to cool the condenser 3.

[0054] like Figure 1 As shown, the water spray cooling device 7 includes a water pipe 71 and a water pump 72. The water pump 72 is installed on the water pipe 71. The water inlet end of the water pipe 71 faces the bottom wall of the water storage pan 5, and the water outlet end of the water pipe 71 faces the condenser 3.

[0055] The advantage of this design is that the present invention can be configured with a water spray cooling device 7 consisting of at least a water pipe 71 and a water pump 72. The water pump 72 is directly installed on the water pipe 71, which shortens the water flow path, reduces energy loss, and simplifies the pipeline structure. The water inlet end of the water pipe 71 faces the bottom wall of the water storage pan 5 to ensure effective water intake even at low water levels. The water outlet end of the water pipe 71 faces the condenser 3 and can be used to spray the condenser 3 in a directional manner, which is beneficial for achieving rapid cooling of local high-temperature areas of the condenser 3.

[0056] Alternatively, a rotatable spray head may be installed at the outlet end of the water pipe 71.

[0057] The advantage of this design is that the main function of the spray head is to disperse water into fine droplets, forming a water mist, thereby increasing the contact area with the surface of the condenser 3 and improving evaporation and cooling efficiency. Compared to large-volume spraying, the spray head can more evenly cover the target area, reducing water waste and potentially reducing the energy consumption of the water pump 72. Simultaneously, the periodic or random rotation of the spray head ensures that the water mist coverage area is a dynamically sweeping region. Furthermore, the sweeping path of the spray head can be designed to match the shape of the water storage pan 5 and the condenser 3, ensuring that while cooling the condenser 3, unevaporated water mist after spraying accurately falls back into the water storage pan 5, reducing scattering losses. In addition, this design allows the condenser 3's heat dissipation requirements to be met using only one or two water spray cooling devices 7, simplifying the structure and reducing costs.

[0058] Alternatively, multiple water spray cooling devices 7 may be provided, with the multiple water spray cooling devices 7 fixed at intervals in the water storage pan 5 and located around the condenser 3.

[0059] The present invention does not limit the number of water spray cooling devices 7. Optionally, the water spray cooling devices 7 can be set to three, four or other values. In addition, multiple water spray cooling devices 7 can be fixed at intervals in the water storage pan 5 and located on the same side of the condenser 3 to meet the cooling requirements of one side of the condenser 3.

[0060] The advantage of this design is that by utilizing the coordinated spraying of multiple water spray cooling devices 7 in different zones, uniform cooling can be achieved across the entire surface of the condenser 3, making it particularly suitable for large and irregularly shaped condensers 3. Simultaneously, through the superposition effect of water flow, adjacent water spray cooling devices 7 can form a continuous wet film on the surface of the condenser 3, extending the evaporation time, increasing the heat exchange efficiency per unit volume of water, better utilizing defrosting water, and improving the heat dissipation effect of the condenser 3 inside the refrigerator.

[0061] Alternatively, the outlet end of the water pipe 71 is equipped with a valve for adjusting the water flow.

[0062] In practical applications, the valve opening degree can be set to be positively correlated with the surface temperature of the condenser 3, or the valve opening degree can be set to be positively correlated with the water level in the water storage pan 5.

[0063] The advantage of this design is that by adjusting the water flow in real time through the valve, it can match the heat load difference of condenser 3 at different times (such as increasing the water flow when the temperature of condenser 3 is too high, and decreasing the water flow when the temperature of condenser 3 is moderate), thereby achieving precise cooling and avoiding the waste of defrosting water in the "constant flow" mode.

[0064] Alternatively, the partition plate 6 is fixedly connected to one end of the condenser 3 placed inside the water storage pan 5, and a gap is left between the partition plate 6 and the side wall of the water storage pan 5 so that the upper water storage part 51 and the lower water storage part 52 can communicate with each other.

[0065] The advantage of this design is that the partition plate 6 is fixedly connected to the condenser 3, eliminating the need for an independent support, and the stability of the partition plate 6 is enhanced by the weight of the condenser 3 itself. At the same time, by leaving a gap between the partition plate 6 and the side wall of the water storage pan 5, the upper water storage section 51 and the lower water storage section 52 can be interconnected without the need for additional connecting pipes, etc., which reduces costs.

[0066] Further optional, such as Figure 3 , Figure 4 As shown, the condenser heat dissipation structure of this refrigerator also includes: a fan 4, which is fixed on the water storage pan 5, and the fan 4 and the water spray cooling device 7 are located on both sides of the condenser 3.

[0067] The advantage of this design is that by arranging the fan 4 and the water spray cooling device 7 on both sides of the condenser 3, a bidirectional heat dissipation path of "spray-air cooling" is formed. Water spray cooling relies on evaporation to absorb heat, while the fan 4 accelerates airflow, carrying away residual heat and promoting water droplet diffusion. Together, they ensure that heat is dissipated simultaneously on both sides of the condenser, improving heat dissipation efficiency. In addition, by introducing forced convection through the fan 4, even when the spray efficiency is limited, air cooling can still be used to assist heat dissipation, ensuring stable cooling of the condenser 3 under different environments.

[0068] Alternatively, a water level detector may be installed inside the water storage pan 5. The number of water level detectors may be multiple, including a water level detector for detecting low water levels inside the water storage pan 5 and a water level detector for detecting high water levels inside the water storage pan 5.

[0069] The advantage of this design is that it enables the water level detector and the water spray cooling device 7 to be linked. When the water level in the water storage pan 5 is low, the water spray cooling device 7 will not be turned on, thus protecting the water spray cooling device 7 and extending its service life.

[0070] This utility model also provides a refrigerator, which has a compressor compartment, and the compressor compartment has a compressor 2, a condenser 3 and a refrigerator condenser heat dissipation structure as described above.

[0071] The advantage of this design is that, because this utility model is equipped with a superior refrigerator condenser heat dissipation structure for the external condenser 3, this refrigerator condenser heat dissipation structure is equipped with a water storage tray 5 and a water spray cooling device 7. The water storage tray 5 can be used to store defrost water and fix the condenser 3 in the water storage tray 5, so that the defrost water in the water storage tray 5 submerges part of the pipes of the condenser 3, thereby achieving a certain degree of cooling by utilizing the defrost water. The water spray cooling device 7 can spray the defrost water in the water storage tray 5 onto the condenser 3, making better use of the defrost water to cool the condenser 3. This utility model not only makes full use of defrost water to improve the heat dissipation effect of the condenser 3 inside the refrigerator and improves the refrigeration efficiency, but also solves the reliability problem caused by the high temperature of the condenser 3 and other components due to the inability to dissipate heat in the compressor compartment.

[0072] To better understand, the following description uses a preferred embodiment of the present invention as an example to fully illustrate the refrigerator condenser heat dissipation structure and the refrigerator proposed in the present invention.

[0073] Please see Figures 5 to 7 The refrigerator proposed in this utility model is a refrigerator in which the condenser 3 is designed inside the compressor compartment. The compressor compartment is equipped with a supporting base plate 1, a compressor 2, a condenser 3, and a refrigerator condenser heat dissipation structure. The refrigerator condenser heat dissipation structure includes a water storage tray 5, a partition plate 6, and a water spray cooling device 7.

[0074] The water storage pan 5 includes a bottom wall and side walls that together enclose the water storage space. The condenser 3 and fan 4 are vertically mounted on the water storage pan 5, with only their bottom ends inside the pan, the rest exposed. The condenser 3 and fan 4 have fixing protrusions for fixed connection to a partition plate 6. The partition plate 6 divides the water storage space of the water storage pan 5 into an upper water storage section 51 and a lower water storage section 52. A gap is left between the partition plate 6 and the side walls of the water storage pan 5 to allow communication between the upper water storage section 51 and the lower water storage section 52. The water storage pan 5 also has a drain pipe 8. The inlet of the drain pipe 8 is connected to a water receiving pan (located above the condenser 3 or below the evaporator), and the outlet of the drain pipe 8 is connected to the lower water storage section 52 of the water storage pan 5. The water spray cooling device 7 includes a water pump 72 fixed on the partition plate 6 and a water pipe 71 fixed on the water pump 72. The inlet end of the water pipe 71 faces the bottom wall of the water storage pan 5, and the outlet end of the water pipe 71 faces the condenser 3. A spray nozzle is installed at the outlet end of the water pipe 71. Meanwhile, the water spray cooling device 7 and the fan 4 are located on both sides of the condenser 3.

[0075] In addition, a temperature sensor is installed on the condenser 3 of the refrigerator, and a water level sensor is installed in the water reservoir 5. The opening and closing of the water pump 72 is determined by the condenser temperature, the ambient temperature, and the water level in the water reservoir. When the water level in the water reservoir 5 is high enough and the condenser temperature is too high, water is sprayed onto the condenser 3 to improve the refrigerator's cooling efficiency and reliability.

[0076] like Figure 8 As shown, the method for controlling the heat dissipation of the condenser inside the refrigerator is as follows:

[0077] When the refrigerator is powered on, the water level Hn in the water tank is checked every 5 minutes.

[0078] If Hn≤H0 (H0 is the water level in the storage pan reaching the warning value), then the next water spraying command will not be issued;

[0079] If Hn≥H0, proceed to the next step of the judgment;

[0080] Detect the ambient temperature Th and the condenser temperature Tn;

[0081] When Tn≤T0 (T0 is the set reliable temperature of the condenser, which varies depending on the design of the refrigerator; the threshold of T0 is Th+30℃), the water pump will not be turned on, and the process will return to step one. After waiting for 5 minutes, the water level will be checked again for a new judgment.

[0082] If Tn≥T0, spray water continuously for 1 minute, and then check the water level again 5 minutes after the last water level check to make a judgment.

[0083] The refrigerator condenser heat dissipation structure and refrigerator proposed in this utility model are equipped with a water storage tray 5 and a water spray cooling device 7. Defrost water is stored in the water storage tray 5. When the condenser 3 temperature is too high, the water spray cooling device 7 draws out the defrost water from the water storage tray 5 and sprays it onto the condenser 3, thereby cooling the condenser 3 and improving the refrigerator's cooling efficiency and reliability. Furthermore, a partition plate 6 divides the water storage tray 5 into upper and lower parts. The partition plate 6 reduces the contact area between the water below the partition plate and the outside air, thus reducing the evaporation of the lower water layer and preventing the defrost water in the water storage tray 5 from completely evaporating. When the condenser 3 temperature is too high, the water pump 72 is activated to spray water. The water sprayed onto the condenser 3 is relatively low in temperature and can directly cool the condenser 3. Some water also carries away more heat through evaporation. Water droplets that do not evaporate fall into the water storage tray 5 to complete the circulation, reducing water consumption.
