Description

Technical Field

[0001] This invention relates to the field of refrigerator technology, and more particularly to a condenser heat dissipation device, its control method, and a refrigerator. Background Technology

[0002] As people's living standards improve, their demands for refrigerator performance are increasing. Currently, integrated home refrigeration is the mainstream application scenario, and built-in refrigerators, which save space and blend seamlessly with cabinetry, are more favored by consumers. The heat dissipation efficiency of a refrigerator's refrigeration system directly affects its cooling efficiency, and built-in refrigerators have even higher requirements for heat dissipation. There are two common methods for refrigerator heat dissipation: one uses a side panel condenser, and the other combines a microchannel condenser or a rotary fin condenser in the compressor compartment with a fan. Using a microchannel condenser combined with a fan provides better heat dissipation, but it is very expensive, and there is insufficient space in the compressor compartment of small-capacity refrigerators to accommodate microchannel or rotary fin condensers. On the other hand, heat dissipated by a side panel condenser cannot be effectively transferred outwards, resulting in poor condenser heat dissipation and affecting refrigerator performance.

[0003] In some existing technologies, the compressor and condenser are both located in the compressor compartment, and a water pump is used to periodically draw condensate from the water storage box to the evaporator box. This has problems such as complex structure and logic, high cost, and insufficient space in the compressor compartment.

[0004] In other existing technologies, a single fan is placed above the condenser, and a water collection tray and a fan are installed at the bottom of the housing. This requires a lot of space at the bottom of the housing, and there is also a waste of space in the compressor chamber. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a condensation heat dissipation device and its control method, as well as a refrigerator.

[0006] The present invention adopts the following technical solution:

[0007] The first aspect of this invention provides a condensation and heat dissipation device, comprising: a compressor chamber, a base plate assembly, and a condensation and heat dissipation plate; the bottom of the compressor chamber is connected to the condensation and heat dissipation plate via the base plate assembly, and a condenser is disposed within the condensation and heat dissipation plate; a first fan assembly, a compressor, and a second fan assembly are sequentially disposed on the inner bottom of the compressor chamber, the first fan assembly and the second fan assembly having the same orientation; a drain pipe is disposed on one side of the compressor, one end of the drain pipe being connected to the evaporator drain port of the housing, and the other end being fixed to the base plate assembly through a through hole, for introducing defrosting water from the drain port into the condensation and heat dissipation plate to dissipate heat from the condenser; rectangular openings are also symmetrically disposed at two corners of the base plate assembly, the rectangular openings forming an air inlet and an air outlet with the side wall of the compressor chamber; the compressor chamber is connected to the condensation and heat dissipation plate via the air inlet and the air outlet.

[0008] According to the aforementioned condensation and heat dissipation device, a compressor rear cover is provided at the back of the compressor chamber, and ventilation holes are provided on the compressor rear cover for heat dissipation of the compressor chamber.

[0009] According to the condensation and heat dissipation device, the base plate assembly includes a base plate, and a windproof structure is provided on one side of the base plate to realize that the compressor chamber and the condensation and heat dissipation plate exchange heat only through the air inlet and the air outlet.

[0010] According to the condensation and heat dissipation device, the first fan assembly includes: a fan base, a fan, a fan bracket, and a temperature sensor; the fan bracket is provided on the top of the fan base, the fan is provided on the fan bracket, and the temperature sensor is also provided on one side of the fan bracket; the second fan assembly has the same structure as the first fan assembly.

[0011] According to the condensation and heat dissipation device, the inner sidewall of the condensation and heat dissipation plate is provided with a first shock-absorbing block structure, the bottom center of the inner side of the condensation and heat dissipation plate is provided with a second shock-absorbing block structure, and the second shock-absorbing block structure is provided with a third shock-absorbing block structure on both sides. The condenser is coiled around the shock-absorbing block structure. The sidewall of the condensation and heat dissipation plate is provided with heat dissipation holes for heat dissipation of the condenser.

[0012] According to the condensation heat dissipation device, the bottom of the condensation heat dissipation plate is provided with a drain pipe structure for draining excess defrosting water.

[0013] A second aspect of the present invention provides a control method for a condensation and heat dissipation device, comprising the following steps:

[0014] During the defrosting process and for a preset period after defrosting, the first fan assembly operates at a higher speed than the second fan assembly.

[0015] After defrosting is complete and the preset time has been reached, if the temperature of the first fan assembly is lower than that of the second fan assembly, the speed of the first fan assembly will be higher than that of the second fan assembly; otherwise, the speed of the first fan assembly will be lower than that of the second fan assembly.

[0016] A third aspect of the present invention provides a refrigerator, including the above-described condensation and heat dissipation device.

[0017] A fourth aspect of the present invention provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the computer program, when loaded onto the processor, implements the control method described above.

[0018] The fifth aspect of the present invention provides a storage medium comprising a stored program, wherein the program, when running, controls the device where the storage medium is located to execute the control method described above.

[0019] Compared with the prior art, the beneficial effects of the present invention include at least the following:

[0020] 1. This invention, by placing the condenser inside the condenser cooling plate, not only allows for extra volume within the compressor compartment to accommodate fan assemblies and other devices, thus meeting the needs of refrigerator compressor compartments of any size, but also reduces the total amount of heat generated within the compressor compartment. Furthermore, low-temperature defrosting water is introduced into the condenser cooling plate through a drain pipe, further dissipating heat from the condenser. A first fan assembly draws air from the condenser cooling plate through an air inlet and blows it towards the compressor, while a second fan assembly blows the air from the first fan assembly into the condenser cooling plate through an air outlet, circulating heat between the compressor compartment and the condenser cooling plate to achieve rapid heat dissipation. In short, it employs both water cooling and air cooling to solve the heat dissipation problem of the compressor and condenser, and improves heat dissipation efficiency.

[0021] 2. This invention designs a control method that enables the compressor to be cooled primarily by the air inside the condenser when the air temperature inside the condenser is low, and to be cooled primarily by the low-temperature air from the external environment when the temperature inside the condenser is high, thereby improving heat dissipation efficiency.

[0032] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0034] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0035] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0036] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0038] During refrigerator operation, compressor 9 compresses the refrigerant into a high-temperature, high-pressure gaseous refrigerant; compressor 9 generates a large amount of heat during operation; and even more heat is generated during the condensation of the high-temperature refrigerant. Typically, both compressor 9 and condenser 12 are located within the compressor compartment 1, resulting in excessive heat concentration that is difficult to dissipate.

[0039] like Figure 1-8 As shown, Embodiment 1 of the present invention provides a condensation and heat dissipation device, including: a compressor chamber 1, a base plate assembly 2, and a condensation and heat dissipation plate 11.

[0040] The bottom of the compressor chamber 1 is connected to the condenser heat sink 11 via the base plate assembly 2, and the condenser heat sink 11 is equipped with a condenser 12.

[0041] The compressor chamber 1 is provided with a first fan assembly 31, a compressor 9 and a second fan assembly 32 in sequence at the bottom of the inner side. The first fan assembly 31 and the second fan assembly 32 have the same orientation.

[0042] Preferred, but not limiting, such as Figure 2 As shown, in this embodiment, the first fan assembly 31 faces the compressor 9, and the second fan assembly 32 faces away from the compressor 9; in other embodiments, the second fan assembly 32 faces the compressor 9, and the first fan assembly 31 faces away from the compressor 9.

[0043] The compressor 9 is also provided with a compressor exhaust port 91.

[0044] The compressor 9 is provided with a drain pipe 5 on one side. One end of the drain pipe 5 is connected to the evaporator drain port of the housing 10, and the other end is fixed to the base plate assembly 2 through the through hole 212. It is used to introduce the defrosting water from the drain port into the condenser heat dissipation plate 11 to dissipate heat from the condenser 12.

[0045] The base plate assembly 2 is also provided with rectangular openings at its two corners, which together with the side wall of the compressor chamber 1 form an air inlet 81 and an air outlet 82.

[0046] The air inlet 81 is located on the back side of the first fan assembly 31, and the air outlet 82 is located on the front side of the second fan assembly 32.

[0047] The compressor chamber 1 is connected to the condenser cooling plate 11 through the air inlet 81 and the air outlet 82.

[0048] The present invention reduces the total amount of heat generated in the compressor chamber 1 by placing the condenser 12 inside the condenser heat dissipation plate 11, and introduces low-temperature defrosting water into the condenser heat dissipation plate 11 through the drain pipe 5 to further dissipate heat from the condenser 12.

[0049] The present invention places the condenser 12 inside the condenser heat dissipation plate 11, thereby providing extra volume in the compressor chamber 1 for installing other devices such as fan assemblies.

[0050] The first fan assembly 31 of the present invention draws out the air in the condenser heat sink 11 through the air inlet 81 and blows it toward the compressor 9. The second fan assembly 32 blows the air blown out by the first fan assembly 31 into the condenser heat sink 11 through the air outlet 82, forming a circulating heat exchange to achieve a rapid heat dissipation effect.

[0051] The press chamber 1 is provided with a press rear cover 7 at the back, and the press rear cover 7 is provided with ventilation holes for heat dissipation of the press chamber 1.

[0052] Preferably, but not limitingly, the press rear cover 7 is provided with a first ventilation hole 71, a second ventilation hole 72 and a third ventilation hole 73 in sequence.

[0053] Preferably, but not limitingly, the first fan assembly 31 is located on one side of the first vent 71 and on the other side of the second vent 72.

[0054] The first fan assembly 31 includes: a fan base 311, a fan 312, a fan bracket 313, and a temperature sensor 314;

[0055] The top of the fan base 311 is provided with a fan bracket 313, the fan bracket 313 is provided with a fan 312, and a temperature sensor 314 is also provided on one side of the fan bracket 313.

[0056] The second fan assembly 32 has the same structure as the first fan assembly 31.

[0057] The first fan assembly 31 of the present invention can also draw in air from the external environment through the first ventilation hole 71 and blow it toward the compressor 9. The second fan assembly 32 can also draw in air from the external environment through the second ventilation hole 72. The drawn-in air flows through the compressor 9 to dissipate heat from the compressor 9. The second fan assembly 32 discharges the air blown out by the first fan assembly 31 and the air drawn in from the external environment through the second ventilation hole 72 into the external space through the third ventilation hole 73, forming a circulating heat exchange to achieve a rapid heat dissipation effect.

[0058] The inner wall of the condenser cooling plate 11 is provided with a first shock-absorbing block structure 113, the bottom center of the inner side of the condenser cooling plate 11 is provided with a second shock-absorbing block structure 114, and the second shock-absorbing block structure 114 is provided with a third shock-absorbing block structure 115 on both sides. The condenser 12 is coiled around the shock-absorbing block structure. The side wall of the condenser cooling plate 11 is provided with heat dissipation holes 111 for heat dissipation of the condenser 12.

[0059] The present invention fixes the condenser 12 with a shock-absorbing block structure, which can effectively reduce the risk of pipe collision, wear and fatigue fracture caused by vibration, extend the service life of the equipment, enhance the stability of the pipeline, reduce leakage at the connection or loosening of equipment parts caused by vibration, and ensure the efficient operation of the condenser.

[0060] like Figure 4 As shown in the figure, this embodiment provides a schematic diagram of a single-layer condenser 12; in other embodiments, the condenser may also have multiple layers.

[0061] The bottom of the condenser heat sink 11 is provided with a drain pipe structure 112 for draining excess defrosting water.

[0062] Preferably, but not limitingly, the area of ​​the condenser heat sink 11 is 2 to 3 times that of a conventional heat sink, thus increasing the length of a single-layer condenser. By increasing the length of the single-layer condenser, the number of condenser layers can be reduced, thereby reducing the height of the condenser heat sink 11, which facilitates installation. At the same time, the reduced height of the condenser heat sink 11 can reduce the depth of the defrosting water, increase the effective contact area between the condenser and the defrosting water, and improve the heat dissipation effect.

[0063] The height of the defrosting water is lower than that of the heat dissipation hole 111.

[0064] The base plate assembly 2 includes a base plate 21, and a windproof structure 211 is provided on one side of the base plate 21 so that the compressor chamber 1 and the condenser heat sink 11 can exchange heat only through the air inlet 81 and the air outlet 82.

[0065] The windproof structure 211 is fitted to the press rear cover 7.

[0066] The present invention uses a vertically arranged windbreak structure 211 to fit the rear cover 7 of the press, so that the heat exchange between the press chamber 1 and the condenser heat sink 11 is only through the air inlet 81 and the air outlet 82, which further improves the working efficiency of the fan assembly and thus further improves the heat dissipation efficiency.

[0067] The base plate 21 is provided with bolts 23 for fixing the compressor 9.

[0068] The base plate 21 is also provided with a fixing connector for fixing the first fan assembly 31 and the second fan assembly 32.

[0069] The base plate 21 is also provided with a first shock-absorbing rubber ring 221 for fixing the condenser inlet 121 and a second shock-absorbing rubber ring 222 for fixing the condenser outlet 122.

[0070] The top of the base plate assembly 2 is also provided with a first fan assembly 31 and a second fan assembly 32 located on both sides of the compressor 9.

[0071] The bottom of the base plate assembly 2 is equipped with casters 6.

[0072] Working principle:

[0073] The condenser cooling plate 11 dissipates heat through the heat dissipation holes 111. At the same time, the defrost water after the refrigerator defrosts flows into the condenser cooling plate 11 through the drain pipe 5. The low temperature defrost water exchanges heat with the high temperature condenser 12. The condenser 12 dissipates heat, and the defrost water absorbs heat and evaporates.

[0074] When the fan assembly malfunctions or other conditions prevent it from working properly, the compressor chamber 1 can dissipate heat naturally through the ventilation holes, air inlet 81, and air outlet 82 provided on the compressor rear cover 7.

[0075] When the fan assemblies are working normally, the first fan assembly 31 draws in air from the condenser heat sink 11 through the air inlet 81 and absorbs cold air below the temperature of the compressor compartment 1 from the first ventilation hole 71 and blows it toward the compressor 9; the second fan assembly 32 draws in air blown from the first fan assembly 31 and absorbs cold air below the temperature of the compressor compartment from the second ventilation hole 72. Part of the air is blown out of the compressor compartment through the third ventilation hole 73, and the other part is returned to the condenser heat sink 11 through the air outlet 82. The second fan assembly 32 absorbs cold air below the temperature of the compressor compartment from the second ventilation hole 72 and flows through the compressor 9 to dissipate heat for the compressor 9. When the first fan assembly 31 and the second fan assembly 32 are working, the heat generated by the condenser 12 and the compressor 9 achieves a rapid heat dissipation effect through defrosting water heat exchange and air circulation.

[0076] This invention provides a dual cooling system for the compressor and condenser using a condensation heat dissipation device and dual fans, which greatly improves heat dissipation efficiency.

[0077] Embodiment 2 of the present invention provides a control method for a condensation heat dissipation device, comprising the following steps:

[0078] Step S1: During the defrosting process of the evaporator and within a preset time T1 after the defrosting is completed, the speed of the first fan assembly 31 is higher than that of the second fan assembly 32.

[0079] Step S2: After the evaporator defrosts and a preset time T1 is reached, if the temperature detected by the temperature sensor of the first fan assembly 31 is lower than the temperature detected by the temperature sensor of the second fan assembly 32, then the speed of the first fan assembly 31 is higher than the speed of the second fan assembly 32; otherwise, the speed of the first fan assembly 31 is lower than the speed of the second fan assembly 32.

[0080] The present invention achieves the following through the above control method: when the air inside the condenser 11 is low, the compressor 9 is mainly cooled by the air inside the condenser 11; when the temperature of the condenser 11 is high, the compressor 9 is mainly cooled by the low-temperature air in the external environment, thereby improving the cooling efficiency of the compressor.

[0081] Embodiment 3 of the present invention provides a refrigerator, including the above-described condensation and heat dissipation device.

[0082] Embodiment 4 of the present invention provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the computer program is loaded onto the processor, it implements the control method described above.

[0083] Embodiment 5 of the present invention provides a storage medium, the storage medium including a stored program, wherein the program controls the device where the storage medium is located to execute the above-described control method during runtime.
