Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a heat dissipation system and a refrigerator comprising the same. Background Art

[0002] Flow rate is a key performance metric for the bottom cooling system of flush-mounted refrigerators. Simulations and experiments have shown that the overall flow rate is strongly correlated with the shape and size of the transition shroud between the condenser and the fan. Therefore, current state-of-the-art methods often adjust the flow rate of the entire bottom cooling system by adjusting the cross-sectional profile or axial length of the transition shroud behind the condenser and in front of the fan to adjust the total flow area of ​​the transition section. The fan is mounted within the air shroud via multiple shaft brackets, one end of which is connected to the fan shaft and the other to the inner wall of the air shroud.

[0003] To reduce flow resistance, increase flow area, and improve overall flow in the bottom cooling system, it's often necessary to optimize the transition cover between the condenser and the fan. By adjusting the transition cover's profile and dimensions, a solution that meets flow requirements can be achieved. However, when modifying the transition cover, flow is often the primary optimization objective, with no consideration given to factors such as aerodynamic noise and structural strength.

[0004] By increasing the cross-sectional area of ​​the transition cover and lengthening the axial length of the transition cover, the total flow area can be increased, thereby increasing the flow rate. Although the flow rate is increased, the accompanying problems are increased aerodynamic noise and reduced structural strength due to changes in the line shape. Moreover, the optimization design process is relatively cumbersome and is mainly based on experience. Therefore, there will also be problems such as long simulation calculation cycle and increased difficulty in testing and remodeling. Utility Model Content

This allows for timely and reliable adjustment of the fan's installation position within the air scoop based on the air volume distribution, facilitating timely flow adjustment and, in turn, improving the heat dissipation performance of the cooling system. Furthermore, based on the principle that the farther the fan is from the condenser, the greater the air volume, the distance adjustment is implemented accordingly based on the detected air volume position, making adjustment convenient and reliable, and achieving intelligent flow control.

[0054] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0055] like Figures 1 to 6 As shown, this embodiment provides a heat dissipation system, which is used for a refrigerator. The heat dissipation system includes a condenser 10, a fan 30 and an air guide cover 40. The fan 30 is installed in the air guide cover 40 through a plurality of shaft brackets 50. The first end of the shaft bracket 50 is fixed to the fan shaft 301 of the fan 30, and the second end is connected to the inner wall of the air guide cover 40. The second end of the shaft bracket 50 is movable relative to the air guide cover 40 so that the distance between the fan 30 and the condenser along the axial direction of the fan 30 is adjustable.

[0056] In this embodiment, the shaft bracket 50 is movable in the air guide cover 40, so that the fan 30 is movable in the air guide cover 40, and the distance between the fan 30 and the condenser is adjustable. Then, the installation position of the fan 30 in the air guide cover 40 can be adjusted as needed according to the air volume distribution of the cooling system, thereby achieving the improvement of the flow rate of the cooling system without sacrificing performance such as aerodynamic noise.

[0057] like Figures 1 to 3As shown, the heat dissipation system further includes a transition cover 20, which is disposed between the condenser 10 and the fan 30. In this embodiment, the provision of a movable fan 30 allows the flow rate of the heat dissipation system to be increased or adjusted without changing the size and shape of the transition cover 20, and without sacrificing performance such as aerodynamic noise.

[0058] It should be noted that the structure of the condenser 10 and the structure of the transition cover 20 are both known structures in the prior art. Accordingly, the structures in the prior art can be adopted. This is well known to those skilled in the art and will not be described in detail here.

[0059] like Figure 1 、 Figure 5 and Figure 6 As shown, as a preferred setting, the heat dissipation system also includes an air volume sensor 70, which is used to capture the air volume in the air scoop 40. The air volume of the air scoop 40 has at least two gears, and the at least two gears include a first gear and a second gear, and the air volume in the second gear is greater than the air volume in the first gear. When the air volume in the air scoop 40 is in the first gear, the shaft bracket 50 moves to a first position in a direction away from the condenser 10. At the first position, the distance between the shaft bracket 50 and the condenser 10 along the axial direction of the fan 30 is a first distance. When the air volume in the air scoop 40 is in the second gear, the shaft bracket 50 moves to a second position in a direction away from the condenser 10. At the second position, the distance between the shaft bracket 50 and the condenser 10 along the axial direction of the fan 30 is a second distance. The first distance is greater than the second distance.

[0060] The above arrangement allows the air volume sensor 70 to promptly detect the air volume distribution within the air scoop 40. This allows for timely and reliable adjustment of the fan 30's installation position within the air scoop 40 based on the air volume distribution, facilitating timely flow adjustment and, in turn, improving the heat dissipation performance of the cooling system. Furthermore, based on the principle that the farther the fan 30 is from the condenser 10, the greater the air volume, the distance adjustment is implemented accordingly based on the detected air volume position, making adjustment convenient and reliable, thereby achieving intelligent flow control.

[0061] Furthermore, the at least two gears may further include a third gear, wherein the air volume in the third gear is greater than that in the second gear, and the maximum adjustable length of the shaft bracket 50 is L. When the air volume in the air scoop 40 is in the first gear, the first distance is L. When the air volume in the air scoop 40 is in the second gear, the second distance is 2L / 3. When the air volume in the air scoop 40 is in the third gear, the distance between the shaft bracket 50 and the condenser 10 along the axial direction of the fan 30 is a third distance, and the third distance is L / 3.

[0062] The first, second, and third gears correspond to weak, strong, and super strong gears, respectively. As the flow rate of the fan 30 increases, the air volume sensor 70 uses the opposite control logic to drive the fan 30 to the corresponding position. The three gears provide three corresponding positions of the fan 30 relative to the air guide 40, meeting common usage requirements while balancing cost, reliability, and convenience of flow rate regulation.

[0063] It should be noted that the specific setting of the maximum adjustable length L can be set accordingly according to actual needs and is not specifically limited here. The above-mentioned 2L / 3 and L / 3 are merely preferred settings. In fact, the above-mentioned second distance and third distance can also be set to other values, which are also not specifically limited here.

[0064] Of course, in other alternative embodiments, the above-mentioned gear positions may be set to other numbers according to actual needs, and no specific limitation is made here.

[0065] like Figures 1 to 4 As shown, the inner wall of the air guide cover 40 is provided with a plurality of slide rails 60 spaced apart in the circumferential direction, and the second ends of the plurality of shaft supports 50 are provided on the plurality of slide rails 60 in a one-to-one correspondence and are movable relative to the plurality of slide rails 60 , and the slide rails 60 are slide grooves.

[0066] Among them, setting the slide rail 60 as a slide groove is conducive to the cooperation between the shaft bracket 50 and the slide rail 60, and can achieve stability during the movement of the shaft bracket 50 with a relatively simple structure.

[0067] It should be noted that, in this embodiment, four shaft supports 50 are schematically provided, and the four shaft supports 50 are evenly arranged in the circumferential direction.

[0068] Reference Figures 1 to 6 It is understood that the air volume sensor 70 is located in the chute. In addition, the air volume sensor 70 is arranged in the chute, and no other structure is required to realize the installation of the air volume sensor 70, which is beneficial to improving the space utilization rate in the air guide cover 40 and protecting the air volume sensor 70.

[0069] Furthermore, the air volume sensor 70 is located at one end of the chute close to the condenser 10. Optionally or alternatively, the air volume sensor 70 is connected to the chute by a hinge.

[0070] Here, the above arrangement is adopted, where the air volume sensor 70 is disposed at one end of the chute near the condenser 10, which is conducive to improving the reliability of air volume detection in the air guide cover 40. The air volume sensor 70 is arranged to be connected to the chute via a hinge, which is convenient for connection, and the position of the air volume sensor 70 relative to the chute is convenient for adjustment, and the air volume sensor 70 is convenient for maintenance.

[0071] It should be noted that the above-mentioned arrangement, through multiple shaft supports 50 and multiple slide rails 60, is conducive to ensuring the stability of the fan 30 when moving in the air guide cover 40, and is further conducive to achieving the stability when adjusting the installation position of the fan 30 in the air guide cover 40, and is further conducive to ensuring the stability of the flow regulation of the heat dissipation system.

[0072] It should also be noted that, in other alternative embodiments, the air volume sensor 70 may also be disposed outside the chute, as long as the air volume in the air guide cover 40 can be detected in a timely and reliable manner.

[0073] Accordingly, in other alternative embodiments, the air volume sensor 70 and the slide groove may also be configured to be connected by other connections, such as configuring the air volume sensor to be connected by gluing the slide groove.

[0074] As a preferred arrangement, the shape of the chute is configured to match the shape of the second end of the shaft bracket 50. Here, configuring the shape of the chute to match the shape of the second end of the shaft bracket 50 facilitates reliable positioning of the chute on the shaft bracket 50, ensures the stability of the shaft bracket 50 when moving within the chute, and facilitates reliable adjustment of the installation position of the fan 30.

[0075] As another preferred arrangement, multiple shaft supports 50 are located in the same plane. Here, multiple shaft supports 50 are arranged to be located in the same plane so that the movement of multiple shaft supports 50 is synchronized, which is conducive to achieving a larger adjustment range in the limited space in the air scoop 40.

[0076] At least Figures 4 to 6 As shown, a plurality of rollers 80 are provided in each chute, and the plurality of rollers 80 are arranged at intervals along the moving direction of the shaft bracket 50. The provision of the rollers 80 is conducive to achieving the reliability and convenience of the movement of the shaft bracket 50 in the chute, and is conducive to achieving the stability and timeliness of the flow regulation of the heat dissipation system, and is also conducive to reducing the overall noise.

[0077] As another preferred arrangement, the roller 80 is driven by a hinge. This arrangement eliminates the need for a more complex drive structure, thereby simplifying the overall structure of the heat dissipation system.

[0078] It should be noted that, in other alternative embodiments, the movement of the shaft support 50 may adopt any other applicable driving part, such as a motor or a cylinder.

[0079] This embodiment also provides a refrigerator including the aforementioned heat dissipation system. Because the heat dissipation system can adjust or increase the heat dissipation system flow rate as needed without changing the shape and size of the transition cover and without sacrificing performance such as aerodynamic noise, a refrigerator employing the aforementioned heat dissipation system can maintain the heat dissipation system within an optimal flow rate range without sacrificing performance such as aerodynamic noise, thereby achieving improved heat dissipation performance and thereby improving the overall performance of the refrigerator.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of protection of the present invention.
