[0030] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application 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 only used to explain the present application and are not used to limit the present application.

[0031] For each of the specific technical features described in the specific embodiments, they can be combined in any appropriate manner without conflict. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, various possible combination methods of each specific technical feature in the present application will not be described separately.

[0032] In the following description, the terms "first / second / ..." only distinguish different objects and do not indicate that there is any same or related relationship between the objects. It should be understood that the orientation descriptions involved, such as "above", "below", "outside", "inside", are all in the normal use orientation. The "left" and "right" directions represent the left and right directions shown in the specific corresponding schematic diagram, which may or may not be the left and right directions in the normal use state.

[0033] It should be noted that the term "comprising", "including" or any other variation thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or apparatus comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of another identical element in the process, method, article or apparatus comprising the element. "Plurality" means greater than or equal to two.

[0034] In the related art, the first radiator is disposed in the first air duct, and the second radiator is disposed in the second air duct. The first air duct and the second air duct are isolated from each other. The first fan is used to dissipate heat from the first radiator, and the second fan is used to dissipate heat from the second radiator. When the refrigerator operates for refrigeration, one of the first radiator and the second radiator needs to operate at a high power to meet the heat dissipation requirements of the refrigerator refrigeration, and the other of the first radiator and the second radiator needs to operate at a low power to avoid condensation and cold leakage of the first radiator or the second radiator. When only the first fan blows air into the first air duct, the first fan makes the heat dissipation efficiency of the first radiator high, and the second radiator relies on natural heat dissipation, and it is difficult for the second radiator to meet the heat dissipation requirements; when only the second fan blows air into the second air duct, the second fan makes the heat dissipation efficiency of the second radiator high, and the first radiator relies on natural heat dissipation, and it is difficult to meet the heat dissipation requirements of the first radiator; when the first fan operates to blow air into the first air duct and the second fan operates to blow air into the second air duct, the heat dissipation requirements of the first radiator and the second radiator are met, but the operation power of the whole refrigerator is large when both the first fan and the second fan are operating. It is difficult to make the whole refrigerator operate at a low power to meet the heat dissipation requirements of the first radiator and the second radiator.

[0035] A refrigerator provided by an embodiment of the present application is shown in Figures 1 to 4 , the refrigerator includes a box body 1, an air duct cover 2, a baffle 3, a first radiator 4, a second radiator 5, a first fan 61 and a second fan 62. The box body 1 has a refrigeration cavity 11 for storing materials. The air duct cover 2 covers the box body 1. An air outlet 21 and an air inlet 22 are provided on the air duct cover 2. The baffle 3 is disposed on the air duct cover 2. The box body 1, the air duct cover 2 and the baffle 3 enclose a first air duct 31 and a second air duct 32 outside the refrigeration cavity 11. The first air duct 31 and the second air duct 32 are communicated with each other. The first radiator 4 is disposed in the first air duct 31, and the second radiator 5 is disposed in the second air duct 32. The first fan 61 is installed on the air duct cover 2 to dissipate heat from the first radiator 4, and the second fan 62 is installed on the air duct cover 2 to dissipate heat from the second radiator 5.

[0036] In the embodiment of the present application, the box body 1, the air duct cover 2 and the baffle 3 enclose a first air duct 31 and a second air duct 32 outside the refrigeration cavity 11. The first fan 61 is used to blow the air flow at the air inlet 22 into the first air duct 31, and the second fan 62 is used to blow the air flow at the air inlet 22 into the second air duct 32. The air flow exchanges heat with the relatively hot first radiator 4 and / or second radiator 5 in the first air duct 31 and / or the second air duct 32, and the air flow with increased temperature after heat exchange flows out from the air outlet 21. The baffle 3 is provided to gather the air flow in the first air duct 31 or the second air duct 32, further improving the heat dissipation efficiency of the first radiator 4 or the second radiator 5. When the refrigeration structure corresponding to the first radiator 4 operates at high power to realize the refrigeration function of the refrigeration cavity, and the refrigeration structure corresponding to the second radiator 5 operates at low power to prevent the second radiator 5 from condensing and leaking cold, the heat dissipation requirement of the first radiator 4 is large, and the heat dissipation requirement of the second radiator 5 is small. The first fan 61 blows air into the first air duct 31 to enable the first radiator 4 to dissipate heat quickly. The first air duct 31 and the second air duct 32 are connected. The air flow velocity in the first air duct 31 is high, and a negative pressure area is formed at the connection of the first air duct 31 and the second air duct 32, causing the low-speed air flow in the second air duct 32 to flow towards the lower pressure area, forming a heat dissipation air flow in the second air duct 32 to dissipate heat from the second radiator 5. When the refrigeration structure corresponding to the second radiator 5 operates at high power to realize the refrigeration function of the refrigeration cavity, and the refrigeration structure corresponding to the first radiator 4 operates at low power to prevent the first radiator 4 from condensing and leaking cold, the heat dissipation requirement of the second radiator 5 is large, and the heat dissipation requirement of the first radiator 4 is small. The second fan 62 blows air into the second air duct 32 to enable the second radiator 5 to dissipate heat quickly. The first air duct 31 and the second air duct 32 are connected. The air flow velocity in the second air duct 32 is high, and a negative pressure area is formed at the connection of the first air duct 31 and the second air duct 32, causing the low-speed air flow in the first air duct 31 to flow towards the lower pressure area, forming a heat dissipation air flow in the first air duct 31 to dissipate heat from the first radiator 4. The first air duct 31 and the second air duct 32 are connected, and the air flow in the first air duct 31 and the air flow in the second air duct 32 affect each other. Only by operating the first fan 61 or the second fan 62 can the heat dissipation of the first radiator 4 and the second radiator 5 be realized, without the need to turn on both the first fan 61 and the second fan 62, and the operating power of the whole refrigerator is small.

[0037] For the convenience of description, the direction indicated by the arrow R1 in the figure is the first direction, and the direction indicated by the arrow R2 is the arrangement direction of the first air duct 31 and the second air duct 32.

[0038] In one embodiment, please refer to Figures 1 to 4 , one end of the baffle 3 is connected to the air duct cover 2, and the other end of the baffle 3 is spaced from the air duct cover 2.

[0039] In the embodiment of the present application, one end of the baffle 3 is connected to the air duct cover 2, and the other end of the baffle 3 is spaced apart from the air duct cover 2. The first air duct 31 and the second air duct 32 are connected at the space between the baffle 3 and the air duct cover 2. The high-speed airflow in one of the first air duct 31 or the second air duct 32 can form a negative pressure zone at the space between the baffle 3 and the air duct cover 2, so that the other of the first air duct 31 or the second air duct 32 forms a heat dissipation airflow. There is no need to set an opening on the baffle 3, and the structure of the baffle 3 is simple and easy to manufacture.

[0040] It is understandable that the other end of the baffle 3 is not limited to being spaced apart from the air duct cover 2. Exemplarily, both ends of the baffle 3 are connected to the air duct cover 2, and a through hole is provided on the baffle 3, which connects the first air duct 31 and the second air duct 32.

[0041] In one embodiment, please refer to Figures 1 to 4 The air outlet 21 and the air inlet 22 are arranged opposite to each other, and the arrangement direction of the air outlet 21 and the air inlet 22 is a first direction. The end of the baffle 3 facing away from the air outlet 21 along the first direction is connected to the air duct cover 2, and the end of the baffle 3 facing the air outlet 21 along the first direction is spaced from the air duct cover 2.

[0042] In the embodiment of the present application, the air outlet 21 and the air inlet 22 are arranged opposite to each other, so as to increase the ventilation effect in the first air duct 31 and the second air duct 32, and improve the heat dissipation effect of the first radiator 4 and the second radiator 5. The end of the baffle 3 facing away from the air outlet 21 in the first direction is connected to the air duct cover 2. The end of the baffle 3 facing away from the air outlet 21 in the first direction can gather the airflow in the first air duct 31 or the second air duct 32 as much as possible, and prevent the airflow from leaking to the other air duct, which is beneficial to the heat dissipation of the first radiator 4 in the first air duct 31 or the second radiator 5 in the second air duct 32. The end of the baffle 3 facing the air outlet 21 in the first direction is spaced from the air duct cover 2, and the connection between the first air duct 31 and the second air duct 32 is close to the air outlet 21, so as to facilitate the airflow of the first air duct 31 and the second air duct 32 with a lower airflow velocity to be directed to the air outlet 21 for discharge.

[0043] It can be understood that the baffle plate 3 is not limited to being connected to the air duct cover 2 at one end away from the air outlet 21 along the first direction, and the baffle plate 3 is not limited to being spaced from the air duct cover 2 at one end toward the air outlet 21 along the first direction. Exemplarily, the end of the baffle plate 3 away from the air outlet 21 along the first direction is spaced from the air duct cover 2, and the end of the baffle plate 3 toward the air outlet 21 along the first risk is connected to the air duct cover 2.

[0044] In one embodiment, please refer to Figures 1 to 4 The arrangement direction of the first air duct 31 and the second air duct 32 intersects with the first direction, the air inlet 22, the first radiator 4 and the air outlet 21 are arranged in sequence along the first direction, and the air inlet 22, the second radiator 5 and the air outlet 21 are arranged in sequence along the first direction.

[0045] In the embodiments of the present application, the air inlet 22, the first radiator 4, and the air outlet 21 are arranged in sequence along the first direction. The air inlet 22, the second radiator 5, and the air outlet 21 are arranged in sequence along the first direction. The first radiator 4 is disposed on the flow path of the air flow in the first air duct 31, and the second radiator 5 is disposed on the air flow path of the second air duct 32, improving the heat dissipation effect of the first radiator 4 and the second radiator 5.

[0046] It can be understood that the arrangement directions of the first air duct 31 and the second air duct 32 are not limited to intersecting with the first direction. Exemplarily, the arrangement directions of the first air duct 31 and the second air duct 32 are parallel to the first direction.

[0047] In one embodiment, please refer to Figures 1 to 4 , when projected along the first direction, the projection area of the first air duct 31 and the projection area of the air outlet 21 at least partially overlap, and the projection area of the second air duct 32 and the projection area of the air outlet 21 at least partially overlap.

[0048] In the embodiments of the present application, when projected along the first direction, the projection area of the first air duct 31 and the projection area of the air outlet 21 at least partially overlap, and the projection area of the second air duct 32 and the projection area of the air outlet 21 at least partially overlap. The area of the air outlet 21 is large enough, the air flow in the first air duct 31 can directly flow out from the air outlet 21, the air flow in the second air duct 32 can directly flow out from the air outlet 21, the ventilation of the first air duct 31 and the second air duct 32 is relatively smooth, improving the ventilation efficiency of the first air duct 31 and the second air duct 32, and accelerating the heat exchange of the first radiator 4 and the heat dissipation of the second radiator 5.

[0049] It can be understood that when projected along the first direction, the projection area of the first air duct 31 and the projection area of the air outlet 21 are not limited to at least partially overlapping, and the projection area of the second air duct 32 and the projection area of the air outlet 21 are not limited to at least partially overlapping.

[0050] Exemplarily, when projected along the first direction, the projection area of the first air duct 31 and the projection area of the air outlet 21 do not overlap, and the projection area of the second air duct 32 and the projection area of the air outlet 21 overlap.

[0051] Exemplarily, when projected along the first direction, the projection area of the first air duct 31 and the projection area of the air outlet 21 overlap, and the projection area of the second air duct 32 and the projection area of the air outlet 21 do not overlap.

[0052] In one embodiment, please refer to Figures 1 to 4 , when projected along the arrangement direction of the first air duct 31 and the second air duct 32, the projection areas of the first radiator 4 and the second radiator 5 are located within the projection area of the baffle 3.

[0053] In the embodiment of the present application, when projected along the arrangement direction of the first air duct 31 and the second air duct 32, the projected areas of the first radiator 4 and the second radiator 5 are located within the projected area of the baffle 3. The length of the baffle 3 along the first direction exceeds the lengths of the first radiator 4 and the second radiator 5 along the first direction. The high-speed air flow in the first air duct 31 or the second air duct 32 will first exchange heat with the corresponding heat exchanger and then flow through the gap between the baffle 3 and the air duct cover 2, forming a negative pressure area in the first air duct 31 and the second air duct 32, preventing the high-speed air flow in the first air duct 31 or the second air duct 32 from escaping before dissipating heat from the first radiator 4 or the second radiator 5, which is beneficial to the heat dissipation of the first radiator 4 and the second radiator 5.

[0054] It can be understood that when projected along the arrangement direction of the first air duct 31 and the second air duct 32, the projected areas of the first radiator 4 and the second radiator 5 are located within the projected area of the baffle 3. Exemplarily, when projected along the arrangement direction of the first air duct 31 and the second air duct 32, part of the projected areas of the first radiator 4 and the second radiator 5 are located outside the projected area of the baffle 3.

[0055] In one embodiment, please refer to Figures 1 to 4 , when projected along the arrangement direction of the first air duct 31 and the second air duct 32, at least part of the projected areas of the first radiator 4 and the second radiator 5 do not overlap.

[0056] It should be noted that at least part of the projected areas of the first radiator 4 and the second radiator 5 do not overlap, which may mean that part of the projected areas of the first radiator 4 and the second radiator 5 overlap and part do not overlap, or the projected areas of the first radiator 4 and the second radiator 5 are spaced apart. The projected areas of the first radiator 4 and the second radiator 5 being spaced apart may mean that the contour lines of the projected areas are in contact, but the projected areas have no intersection.

[0057] In the embodiment of the present application, when projected along the arrangement direction of the first air duct 31 and the second air duct 32, at least part of the projected areas of the first radiator 4 and the second radiator 5 do not overlap, and the first radiator 4 and the second radiator 5 are arranged staggeredly in the arrangement direction of the first air duct 31 and the second air duct 32, which can reduce the mutual influence of the heat of the first radiator 4 and the second radiator 5 and is beneficial to the heat dissipation of the first radiator 4 and the second radiator 5.

[0058] It can be understood that when projected along the arrangement direction of the first air duct 31 and the second air duct 32, at least part of the projected areas of the first radiator 4 and the second radiator 5 do not overlap. Exemplarily, when projected along the arrangement direction of the first air duct 31 and the second air duct 32, the projected areas of the first radiator 4 and the second radiator 5 overlap.

[0059] In one embodiment, the refrigerator includes a main refrigeration module and a standby refrigeration module. The main refrigeration module is provided with a first thermoelectric cooler, and the standby refrigeration module is provided with a second thermoelectric cooler. A first radiator 4 is disposed on the main refrigeration module to dissipate heat from the first thermoelectric cooler, and a second radiator 5 is disposed on the standby refrigeration module to dissipate heat from the second thermoelectric cooler.

[0060] In the embodiment of the present application, when the main refrigeration module operates, the first thermoelectric cooler operates at high power to refrigerate the refrigeration chamber 11. The first thermoelectric cooler generates a relatively large amount of heat at the hot end. The first radiator 4 operates at high power to dissipate heat from the first thermoelectric cooler. The second thermoelectric cooler of the standby refrigeration module operates at low power to prevent cold leakage and condensation. The second thermoelectric cooler generates a relatively small amount of heat at the hot end. The second radiator 5 operates at low power to dissipate heat from the second thermoelectric cooler. When the standby refrigeration module operates, the second thermoelectric cooler operates at high power to refrigerate the refrigeration chamber 11. The second radiator 5 operates at high power to dissipate heat from the second thermoelectric cooler. The first thermoelectric cooler of the main refrigeration module operates at low power to prevent cold leakage and condensation. The first thermoelectric cooler generates a relatively small amount of heat at the hot end. The first radiator 4 operates at low power to dissipate heat from the first thermoelectric cooler. The refrigerator is provided with a main refrigeration module and a standby refrigeration module. When one refrigeration module fails, the other refrigeration module can operate for refrigeration without affecting the use of the refrigerator, improving the reliability of the refrigerator.

[0061] It can be understood that the refrigerator is not limited to including a main refrigeration module and a standby refrigeration module. Exemplarily, the refrigerator is only provided with a main refrigeration module.

[0062] It can be understood that the main refrigeration module is not limited to being provided with a first thermoelectric cooler, and the standby refrigeration module is not limited to being provided with a second thermoelectric cooler. Exemplarily, the main refrigeration module is provided with a first evaporation cooler, and the standby refrigeration module is provided with a second evaporation cooler.

[0063] In one embodiment, please refer to Figures 1 to 4 , the air inlet 22 includes a first air inlet 221 and a second air inlet 222. A first fan 61 is located at the first air inlet 221, and a second fan 62 is located at the second air inlet 222.

[0064] In the embodiment of the present application, when the main refrigeration module operates, the first fan 61 operates and the second fan 62 is closed. The first fan 61 is used to blow the air flow at the first air outlet 221 into the first air duct 31 to dissipate heat from the first radiator 4. The first air duct 31 and the second air duct 32 are connected. Affected by the air flow in the first air duct 31, a negative pressure area is formed in the second air duct 32, and a heat dissipation air flow is formed in the second air duct 32 to accelerate the heat dissipation of the second radiator 5. When the standby refrigeration module operates, the second fan 62 operates and the first fan 61 is closed. The second fan 62 is used to blow the air flow at the second air outlet 222 into the second air duct 32 to dissipate heat from the second radiator 5. Affected by the air flow in the second air duct 32, a negative pressure area is formed in the first air duct 31, and a heat dissipation air flow is formed in the first air duct 31 to accelerate the heat dissipation of the first radiator 4. The first fan 61 is located at the first air outlet 221, and the second fan 62 is located at the second air outlet 222, which facilitates the first fan 61 to blow a large amount of air flow at the first air outlet 221 into the first air duct 31 and the second fan 62 to blow a large amount of air flow at the second air outlet 222 into the second air duct 32, improving the ventilation efficiency of the first air duct 31 and the second air duct 32.

[0065] It can be understood that the first fan 61 is not limited to being located at the first air outlet 221, and the second fan 62 is not limited to being located at the second air outlet 222. Exemplarily, the first fan 61 is located in the first air duct 31 away from the first air outlet 221, and the second fan 62 is located in the second air duct 32 away from the second air outlet 222.

[0066] In one embodiment, please refer to Figures 1 to 4 , the air duct cover 2 covers the top of the box body 1, and both the first air duct 31 and the second air duct 32 are located at the top of the box body 1.
