Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a heat dissipation channel assembly structure for a refrigerator. Background Technology

[0002] Currently, high-end air-cooled refrigerators on the market mainly have two heat dissipation methods: bottom heat dissipation and side heat dissipation. Side heat dissipation achieves heat dissipation by naturally exchanging temperature with the outside through the condenser pipe. This method is not only slow in cooling speed but also consumes a lot of electricity. Bottom heat dissipation, on the other hand, uses a turbine fan to blow hot air into the gap at the bottom of the refrigerator door to achieve heat dissipation. Because its heat dissipation part is at the bottom and the heat exchange area is small, this structure is noisy and requires a certain amount of ventilation space at the bottom. In addition, the heat dissipation design of this structure is relatively complex, requiring special air ducts and heat dissipation structures, resulting in relatively high manufacturing costs.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a refrigerator heat dissipation channel component structure that is simple in structure, low in cost, easy to install, has good heat dissipation effect, can reduce power consumption, and is highly practical, so as to overcome the shortcomings of the prior art.

[0005] A refrigerator heat dissipation channel assembly structure designed for this purpose includes a condenser pipe disposed inside the cabinet. The structure is characterized by further including a fan, a heat exchange assembly, and an air outlet assembly. The cabinet is provided with an air duct cavity for accommodating the fan, the heat exchange assembly, and the air outlet assembly. The condenser pipe is connected to the heat exchange assembly. The cabinet is provided with an air inlet and an air outlet respectively connected to the outside. The air inlet, the air duct cavity, the air outlet assembly, and the air outlet are sequentially connected to form a circulating heat dissipation path.

[0006] The heat exchange assembly includes a condenser and an evaporating dish. The fan and condenser are mounted on the evaporating dish and are positioned close to each other. The condensing tube is connected to the condenser.

[0007] The air outlet assembly includes interconnected microchannels and fasteners. The fasteners are fixed to the housing, and the air duct cavity is connected to the air outlet through the microchannels.

[0008] The microchannel is positioned between the fixture and the housing, and a sealant is placed between the microchannel and the housing.

[0009] The condenser is located between the fan and the air outlet assembly, with the fan's outlet facing the condenser.

[0010] The evaporating dish is provided with a first buckle, and the fan is provided with a snap-fit ​​groove. The first buckle and the snap-fit ​​groove are interlocked to fix the fan on the evaporating dish.

[0011] The condenser is provided with a first fixing hole, and the evaporating dish is provided with a second fixing hole. The first fastener passes through the first fixing hole and is then fastened to the second fixing hole to fix the condenser on the evaporating dish.

[0012] The fastener is provided with a T-shaped second buckle, and the micro-channel is provided with a slot. The second buckle and the slot engage with each other to connect the micro-channel and the fastener.

[0013] It also includes a rear cover, which covers the rear side of the air duct cavity, and the air inlet is located on the rear cover.

[0014] The fan is a brushless fan.

[0015] The refrigerator heat dissipation channel assembly structure of this utility model is an improvement on the traditional side heat dissipation method. It adds a heat dissipation channel assembly, which includes a fan, a heat exchange component, and an air outlet component. The heat exchange component includes a condenser and an evaporating dish, and the air outlet component includes interconnected micro-channels and fixing components. When the refrigerator is running, the condenser pipe transfers heat to the condenser, and the fan blows hot air and water vapor above the evaporating dish into the micro-channels to exchange heat with the cold air outside the refrigerator. At the same time, cold air is introduced through the air inlet to form a circulating heat dissipation path. This structure has a large heat exchange area, which can achieve efficient heat dissipation. Combined with forced convection, the heat exchange efficiency is improved. Moreover, the heat dissipation design is simple and does not require special air ducts and heat dissipation structures, thereby reducing manufacturing costs. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See Figures 1-7 The heat dissipation channel assembly structure of this refrigerator includes a condenser pipe (not shown in the figure) installed inside the cabinet 1, as well as a fan 2, a heat exchange component, and an air outlet component. The cabinet 1 is provided with an air duct cavity 3 for accommodating the fan 2, the heat exchange component, and the air outlet component. The air duct cavity 3 is located at the bottom of the cabinet 1. The condenser pipe is connected to the heat exchange component. The cabinet 1 is provided with an air inlet 4 and an air outlet 5 that are respectively connected to the outside. The air inlet 4, the air duct cavity 3, the air outlet component, and the air outlet 5 are connected in sequence to form a circulating heat dissipation path. The heat dissipation channel assembly of this refrigerator is highly versatile and can be adapted to various refrigerator models, simplifying production line adjustments.

[0025] The heat exchange assembly includes a condenser 6 and an evaporating dish 7. The fan 2 and the condenser 6 are mounted on the evaporating dish 7 and are positioned close to each other to form a core heat dissipation module.

[0026] The air outlet assembly includes interconnected microchannels 9 and fasteners 10. The fasteners 10 are fixed to one side of the cabinet 1. The air duct cavity 3 is connected to the air outlet 5 through the microchannels 9. When the refrigerator is running, the condenser tube transfers heat to the condenser 6. The fan 2 blows hot air and water vapor above the evaporating dish 7 into the microchannels 9, and then exhausts them to the outside through the air outlet 5 to exchange heat with the cold air outside the cabinet 1. At the same time, cold air is introduced through the air inlet 4 to form a circulating heat dissipation path, that is, a heat exchange cycle.

[0027] The microchannel 9 is located between the fixing member 10 and the box 1. A sealing element is filled between the microchannel 9 and the box 1. The microchannel 9 and the box 1 are sealed by the sealing element, which is a sealing sponge. This ensures the isolation of hot and cold airflow and prevents the foam material from seeping in during foaming. Moreover, the sealing design of the microchannel 9 and the box 1, combined with forced convection, improves the heat exchange efficiency.

The first buckle 11 and the snap-fit ​​groove 12 are snapped together to fix the fan 2 on the evaporating dish 7. The buckle connection reduces the amount of screws used, thereby reducing the installation complexity and material costs.

[0030] The condenser 6 has a first fixing hole at the bottom and the evaporating dish 7 has a second fixing hole at the top. The first fastener 16 (screw) passes through the first fixing hole and is then fastened to the second fixing hole so that the condenser 6 is fixed on the evaporating dish 7.

[0031] The fastener 10 is bent and has a T-shaped second buckle 13, and the micro channel 9 is provided with a slot 14. The second buckle 13 and the slot 14 are engaged with each other to connect the micro channel 9 and the fastener 10, so as to achieve fast and accurate positioning.

[0032] The fastener 10 is provided with a third fixing hole 17, and the housing 1 is provided with a fourth fixing hole. The second fastener 18 (screw) passes through the third fixing hole 17 and is fastened to the fourth fixing hole so that the fastener 10 is fixed to the housing 1. The fastener 10 is an angle iron.

[0033] The fastener 10 is provided with a through hole 19, and the air duct cavity 3 is connected to the micro channel 9 through the through hole 19.

[0034] It also includes a rear cover 15, which covers the rear side of the air duct cavity 3, and the air inlet 4 is provided on the rear cover 15.

[0035] A compressor 20 is installed inside the air duct cavity 3. The compressor 20 is connected to the condenser 6. The rear cover 15 is the rear cover of the compressor.

[0036] Fan 2 is a brushless fan. The brushless fan and optimized air duct design reduce noise by 4-6 dB and greatly reduce energy consumption, which means reducing power consumption and increasing cooling speed.
