Description

Technical Field

[0001] The invention relates to the technical field of refrigerator manufacturing, in particular to a refrigerator and a condenser assembly thereof. Background Art

[0002] As a component of the refrigerator refrigeration system, the condenser is a type of heat exchanger that can convert gas or steam into liquid and quickly transfer the heat in the tube to the air near the tube. The working process of the condenser is a heat release process, so the temperature of the condenser itself is usually relatively high. In order to improve the working efficiency of the condenser, the heat it carries needs to be conducted away in time.

[0003] At present, the air-cooled condensers commonly used in refrigerators on the market mainly include: microchannel condensers and surface condensers. Among them, the microchannel condenser is expensive and limited by the structure of the refrigerator itself. Some refrigerators are only equipped with a bottom cooling system, and the heat dissipation effect cannot meet the requirements. Therefore, an additional surface condenser is required. The surface condenser is divided into an exposed condenser and a built-in condenser. The overall cost of the exposed condenser is lower than that of the microchannel condenser, but it is usually placed outside the refrigerator and is easy to accumulate dust, thereby affecting the heat dissipation effect of the condenser. In addition, due to the appearance, some users do not accept this refrigerator equipped with an exposed condenser; the cost of the built-in condenser is relatively lower, but the condenser tube is attached to the inner side of the U shell and the back panel through aluminum foil tape, and its heat dissipation efficiency is low, the thermal resistance is large, and it is not conducive to heat dissipation.

[0034] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0035] If the invention involves directions (e.g., up, down, left, right, front, back, outside, inside, etc.) when describing, it is necessary to define the directions involved, such as "In order to clearly express the positions and directions described in the invention, the end close to the operator is the proximal end, and the end far from the operator is the distal end." Or define it with the paper as a reference, with the depth direction of the refrigerator as a reference, etc. Of course, if the positional relationship between the two is defined by mutual reference in the subsequent description, it does not need to be defined here.

[0036] In order to solve the problem of poor heat dissipation effect of microchannel condensers and surface condensers in the prior art, the present invention provides a refrigerator and a condenser assembly thereof.

[0037] like Figure 1-6 As shown, one embodiment of the present invention provides a condenser assembly, comprising: a back plate 1, a cover plate 2, a fan 3, a wind shield 4 and a condenser;

[0038] The cover plate 2 is connected to the back plate 1 to form a housing with an accommodating space, and the cover plate 2 is provided with an air inlet hole 211 and an air outlet hole 221;

[0039] The fan 3 is arranged between the back plate 1 and the cover plate 2, the air inlet 211 is arranged on the cover plate 2, and the air inlet 211 is arranged toward the fan 3, so that the fan 3 can easily inhale air from the air inlet 211;

[0040] The wind shield 4 is respectively connected with the back plate 1 and the cover plate 2 to form an air duct, and the fan 3 is arranged near one end of the air duct and supplies air to the air duct. During use, when the condenser assembly is running, the fan 3 first sucks air through the air inlet 211, and then blows the air into the air duct from the end of the air duct near the fan, and the air runs along the air duct and is finally discharged from the exhaust hole 221;

[0041] The condenser includes an inlet 51, a condenser tube 53 and an outlet 52. The refrigerant flows into the condenser tube 53 from the inlet 51, transfers heat to the condenser tube 53 and dissipates heat outward through the condenser tube 53, and is finally discharged from the outlet 52. The condenser tube 53 is at least partially arranged on the trajectory of the wind in the air duct. During use, the fan 3 continuously inhales external air and sends it into the air duct. The wind travels along the air duct and encounters the condenser tube 53. The condenser tube 53 can be partially or completely located on the trajectory of the wind. The traveling wind absorbs the heat emitted by the refrigerant on the condenser tube 53 and is finally discharged from the exhaust hole 221 on the cover plate 2, thereby achieving the purpose of cooling and dissipating the refrigerant in the condenser tube 53.

[0042] Typically, the cover plate 2 can be configured to include a center plate 21 parallel to the back plate 1 and a plurality of folded edges 22 disposed toward the back plate 1, wherein the plurality of folded edges 22 are connected to the back plate 1. Such a configuration can obtain a relatively regular accommodation space. Of course, other configurations that can ensure that an accommodation space is formed between the cover plate 2 and the back plate 1 are also feasible. The air inlet 211 is disposed on the center plate 21, and the air outlet 221 is disposed on the folded edge 22. Furthermore, in order to improve the efficiency of air exhaust, a plurality of the air outlet 221 are evenly arranged on each folded edge 22.

[0043] Furthermore, the air inlet hole 211 is configured to match the fan 3, and the fan 3 can pass through the air inlet hole 211 and be fixedly connected to the back panel 1. Such a configuration is conducive to the fan 3 sucking air from the air inlet hole. At the same time, the fan 3 can be installed on the back panel 1 or removed from the back panel 1 through the air inlet hole 211, which is convenient for later maintenance.

[0044] Furthermore, the condenser assembly also includes a cover net 31 covering the fan 3, and the fixed part of the cover net 31 is fixedly connected to the center plate 21, so as to prevent relatively large foreign objects in the surrounding environment from being sucked into the air duct and blocking the air duct. In addition, the cover net 31 can also effectively protect the fan 3 and prevent hard objects from colliding with the fan 3 and causing damage to the fan 3.

[0045] When removing the heat from the condenser tube 53, in order to reduce the space occupied by the condenser assembly, the wind shield 4 is respectively abutted against the center plate 21 and the cover plate 2 to form a spiral air duct, and the fan 3 is arranged at one end close to the center of the spiral air duct to supply air to the air duct. Then, the condenser tube 53 is inserted into the spiral air duct surrounded by the wind shield.

[0046] Regarding the setting of the wind shield 4, the wind shield 4 in this embodiment includes a first connecting plate 41 and a second connecting plate 42, the first connecting plate 41 and the second connecting plate 42 are respectively abutted against the back plate 1 and the center plate 21 to form a spiral air duct, one end of the first connecting plate 41 is arranged close to the fan 3, the other end of the first connecting plate 41 extends along the volute line to a position away from the fan 3 and is connected to one end of the second connecting plate 42, and the other end of the second connecting plate 42 extends along the U-shaped spiral to a position on the center plate 21 close to the folded edge 22. From the overall point of view, the first The connecting plate 41, the second connecting plate 42, the back plate 1 and the center plate 21 still form a spiral air duct from the inside to the outside: wherein, the volute-shaped air duct formed by the first connecting plate 41, the center plate 21 and the back plate 1 facilitates the air sucked in by the fan 3 to smoothly enter the air duct; and the second connecting plate 42, the center plate 21 and the back plate 1 form a U-shaped spiral air duct portion in the entire spiral air duct. This U-shaped spiral air duct allows the air sucked in from the outside to stay therein for a short time, which is more conducive to heat exchange between this part of the air and the condenser 53, thereby absorbing the heat on the condenser 53.

[0047] Furthermore, in order to make the part of the condenser 53 to be heat exchanged be completely and evenly distributed in the entire air duct, thereby improving the efficiency of heat exchange. Therefore, the inlet 51 and the outlet 52 are arranged at the end of the air duct away from the fan 3; the condenser 53 includes an inlet pipe 531 along the side of the air duct away from the fan and an outlet pipe 532 along the side of the air duct close to the fan, one end of the inlet pipe 531 is connected to the inlet 51, and the other end of the inlet pipe 531 extends along the air duct to the vicinity of the connection 43 between the first connecting plate 41 and the second connecting plate 42 and is connected to one end of the outlet pipe 532, and the other end of the outlet pipe 532 is connected to the outlet 52. With this design, the entire condenser 53 will be located in the air duct, and the inlet pipe 531 and the outlet pipe 532 are evenly distributed in the entire air duct, which fully improves the utilization rate of the air duct and greatly improves the effect of heat exchange.

[0048] In addition, the inlet pipe 531 is abutted against the wind shield 4 and the center plate 21, and the outlet pipe 532 is abutted against the center plate 21. During the air-cooled heat exchange, the inlet pipe 531 can also dissipate heat through the wind shield 4 and the center plate 21, and the outlet pipe 532 can dissipate heat through the center plate 21, thereby further improving the efficiency of the heat exchange.

[0049] The present invention also provides a second embodiment, which differs from the first embodiment in that the wind shield and the condensation tube are arranged. Figure 7 As shown, in the second embodiment, the wind shield portion 4 includes a plurality of wind shield ribs 44 surrounding the fan, and these wind shield ribs 44 are arranged along the radial direction of the fan 3, and the number of the wind shield ribs is at least 3, so that an effective air duct can be formed, and these wind shield ribs 44 are respectively abutted against the back plate 1 and the center plate 21 to form an air duct, and these air ducts are fan-shaped and surround the fan 3, and the fan 3 is configured to supply air to one end of these fan-shaped air ducts close to the fan 3, and the condenser 53 surrounds the wind shield ribs 44 and is fixedly connected to the center plate 21, one end of the condenser 53 is connected to the inlet 51, and the other end is connected to the outlet 52. During the operation of the condenser assembly, the fan 3 absorbs air from the outside and then blows the air into the fan-shaped air duct opening close to the fan, and these fan-shaped air ducts are trumpet-shaped and enlarged from the end close to the fan to the end away from the fan 3. Therefore, the wind in the air duct is blown onto the condenser 53 through the fan-shaped air duct and takes away the heat on the condenser, and is finally discharged from the exhaust hole 221. Since the condenser 53 is fixedly connected to the center plate 21, the heat can of course be dissipated through the center plate 21, thereby achieving a good heat dissipation effect. Since the arrangement of the remaining components is the same as that in the first embodiment, they will not be described in detail here.

[0050] An embodiment of the present invention also provides a refrigerator, including a box body and a door body for opening and closing the box body, wherein the box body includes an inner tank and an outer shell, wherein the refrigerator also includes the condenser assembly described in the first embodiment and the second embodiment, and the outer shell of the box body forms the back panel 1. During the actual processing process, the condenser assembly can select the side wall of the outer shell as the back panel, or can select the side of the outer shell opposite to the refrigerator door as the back panel.

[0051] In summary, the refrigerator and condenser assembly provided in this embodiment bring the following technical effects:

[0052] 1. Solve the problem of poor heat dissipation effect of microchannel condensers and surface condensers in the prior art;

[0053] 2. Setting the air duct into a U-shaped spiral air duct from the inside to the outside helps the circulating air to stay in the air duct, thereby ensuring the effect of heat exchange;

[0054] 3. The inlet pipe is abutted against the wind shield and the center plate, and the outlet pipe is abutted against the center plate. During the air-cooling heat exchange, the inlet pipe can also dissipate heat through the wind shield and the center plate, while the outlet pipe can dissipate heat through the center plate, further improving the efficiency of heat exchange;

[0055] 4. Multiple air ducts are arranged along the radial direction of the fan. The air absorbed by the fan can be blown toward the condenser along these air ducts, thereby effectively cooling the condenser.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
