Description

Technical Field

[0001] This utility model belongs to the field of refrigerator display technology, and relates to a heat dissipation and ventilation structure for an embedded display in a refrigerator. Background Technology

[0002] The core drawbacks of existing refrigerator displays in terms of heat dissipation and ventilation are insufficient heat dissipation efficiency and poor ventilation stability, which can easily lead to device crashes, component damage, and display malfunctions. These shortcomings stem from multiple factors: the thickness of the refrigerator door is limited by cost and aesthetics, resulting in a compact installation space for the display and narrow heat dissipation channels; functional upgrades increase the heat generated by components such as the driver board and CPU, leading to heat accumulation; ventilation hole designs often have structural compromises that result in blockages by dust and food debris, and the large temperature difference between the inside and outside of the refrigerator can cause condensation, further hindering airflow; some displays use temperature-sensitive materials such as OLEDs, and high-temperature environments accelerate their performance degradation. Conventional solutions include three categories: adding an aluminum plate or other heat sink to the back of the display to conduct heat; adding a small cooling fan for forced ventilation; and reserving ventilation holes to rely on natural convection for heat dissipation. However, these methods have significant drawbacks: the thermal conductivity of a single heat sink decreases after long-term use, failing to meet the heat dissipation requirements of high-power components; cooling fans generate noise, affecting user experience, and have a limited lifespan, easily leading to component overheating and damage after failure, requiring professional repair. Therefore, there is an urgent need for a heat dissipation and ventilation structure for refrigerator-embedded displays to solve these problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heat dissipation and ventilation structure for an embedded display in a refrigerator, thereby solving the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a heat dissipation and ventilation structure for a refrigerator embedded display, comprising: a back shell and a display screen assembly, wherein a set of front shells for wrapping the display screen assembly is provided on the front side of the back shell, and a set of display screen assemblies for displaying the refrigerator status is provided inside the front side of the front shell. The display assembly includes an outer frame and a lower heat collection base. The front cross-section of the outer frame is a rectangular ring structure. The upper left side of the outer frame is provided with an inner ventilation plate for dissipating heat from the inside of the display. The inner ventilation plate has three sets of ventilation holes. The left side of the outer frame is provided with two sets of inner heat conduction groups for evenly distributing heat from the display. The two sets of inner heat conduction groups are arranged symmetrically from top to bottom.

[0005] In a preferred embodiment, each set of internal heat-conducting groups is equipped with several sets of internal heat-conducting sheets, which are made of an aluminum alloy material. Each set of internal heat-conducting groups is provided with several sets of heat-conducting core columns for conducting heat.

[0006] In a preferred embodiment, the heat-conducting core column is made of a metallic copper material, and a set of lower heat-collecting bases for uniformly dispersing heat are provided at the lower end of several sets of heat-conducting core columns. The lower heat-collecting bases are made of a metallic copper material and are integrally connected and fixed with several sets of heat-conducting core columns.

[0007] In a preferred embodiment, the lower heat collection base is provided in two sets, and an inner heat exchange seat for collecting and dispersing heat is provided between the two sets of lower heat collection bases. The inner heat exchange seat has a hollow structure inside. In actual use, when the refrigerator embedded display starts to work, its internal drive board will generate heat due to operation. This heat will first be transferred to the associated components. The heat will gradually diffuse and be captured by the inner heat conduction group located on the left side inside the outer frame. The inner heat conduction sheet in the inner heat conduction group, with the good thermal conductivity of aluminum alloy, will quickly absorb the surrounding heat and then conduct the heat to the heat conduction core column in the group. Since the heat conduction core column is made of copper, it has excellent thermal conductivity and can quickly transfer the heat downward to the lower heat collection base that is integrally connected and fixed with it. The two sets of lower heat collection bases will collect the heat they have collected and transport it to the inner heat exchange seat located between them. The hollow structure inside the inner heat exchange seat provides space for temporary storage and further dispersion of heat, so that the heat can be distributed more evenly and avoid excessive local heat concentration.

[0008] In a preferred embodiment, the internal heat-conducting assembly is provided with an internal heat dissipation fan for laterally dispersing heat, the internal heat exchange seat is in contact with the lower heat collection base, and the right side of the internal heat exchange seat is provided with two sets of conduits for conducting heat.

[0009] In a preferred embodiment, the upper right end of the conduit is provided with several sets of internal suction tubes for extracting heat from the display. The cross-section of the internal suction tube is an inverted trapezoidal structure, and the internal suction tube has a structure that is wider at the top and narrower at the bottom.

[0010] In a preferred embodiment, the inner suction cylinder includes a connecting seat and an outlet pipe. The inner suction cylinder is provided with a set of connecting seats for support. The upper end of the connecting seat is provided with a set of inner sealing plates for preventing heat dissipation. The upper end of the inner sealing plates is provided with three sets of guide turbines for drawing out heat.

[0011] In a preferred embodiment, the lower left side of the guide fan is provided with a set of guide pipes for introducing heat, and the lower right side of the guide fan is provided with a set of outlet pipes for discharging heat. Several sets of inner suction cylinders are provided with an inner support frame for positioning and fixing them. The lower right side of the inner support frame is provided with an inner drive plate for driving the display. In actual use, the two sets of conduits on the right side of the inner heat exchange seat begin to conduct heat, transferring the dispersed heat to several sets of inner suction cylinders on the upper right side of the conduits. The inner suction cylinders are positioned and fixed by the inner support frame, and their cross-section is an inverted trapezoidal structure, wider at the top and narrower at the bottom. The internal connecting seat provides support, and the inner sealing plate at the upper end of the connecting seat prevents heat from dissipating randomly. The three sets of guide fans at the upper end of the inner sealing plate start, introducing heat into the inner suction cylinders through the guide pipes, and then discharging the heat outward through the outlet pipes. Simultaneously, the original internal cooling fan continues to run, forming an airflow circulation inside under the fan's action. The heat is also pushed towards the inner ventilation plate located on the upper left side of the outer frame, and discharged into the external environment through the ventilation holes on the inner ventilation plate.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: In actual use, when the refrigerator embedded display starts to work, the internal drive board inside will generate heat due to operation. This heat will first be transferred to the associated components. The heat will gradually diffuse and be captured by the internal heat conduction group set on the left side inside the outer frame. The internal heat conduction sheet in the internal heat conduction group, with the good thermal conductivity of aluminum alloy material, quickly absorbs the surrounding heat and then conducts the heat to the heat conduction core column in the group. Since the heat conduction core column is made of copper metal material, it has excellent heat conduction efficiency and can quickly transfer the heat downward to the lower heat collection base that is integrally connected and fixed with it. The two lower heat collection bases will gather the heat they have collected and transport it to the internal heat exchange seat located between them. The cavity structure inside the internal heat exchange seat provides space for temporary storage and further dispersion of heat, so that the heat can be distributed more evenly and avoid local heat concentration. Two sets of conduits on the right side of the inner heat exchanger begin to conduct heat, transferring the dispersed heat to several sets of inner suction cylinders on the upper right side of the conduits. The outer side of the inner suction cylinders is positioned and fixed by an inner support frame. Its cross-section is an inverted trapezoidal structure, wider at the top and narrower at the bottom. The internal connecting seat provides support, and the inner sealing plate at the upper end of the connecting seat prevents heat from dissipating randomly. The three sets of guide turbine fans at the upper end of the inner sealing plate start, guiding the heat into the inner suction cylinder through the guide pipe, and then dissipating the heat outward through the outlet pipe. At the same time, the original internal cooling fan continues to run, and under the action of the fan, an airflow circulation is formed inside. The heat is also pushed to the inner ventilation plate located on the upper left side of the outer frame, and discharged into the external environment through the ventilation holes on the inner ventilation plate.
