Description

Technical Field

[0001] This utility model relates to the technical field of refrigerator compressors, specifically to a high-efficiency heat dissipation refrigerator compressor housing. Background Technology

[0002] Refrigerators are becoming increasingly widespread, and people's lives are inseparable from them. A refrigerator mainly consists of components such as a compressor, a drying filter, a capillary tube, and an evaporator. It absorbs heat from the cold compartment through a refrigeration cycle and releases it to the outside. Therefore, refrigerators have important requirements for heat dissipation and insulation. Excellent heat dissipation and insulation performance can significantly reduce refrigerator power consumption, improve cooling efficiency, and extend the refrigerator's lifespan. The rational design and optimization of each component of the refrigerator, especially the compressor, plays an extremely important role.

[0003] The compressor is one of the core components of a refrigerator, the heart of the refrigeration system. A compressor is a fluid machine that transforms low-pressure refrigerant into high-pressure refrigerant, releasing a large amount of heat during the compression process. In winter, the average operating temperature of a compressor is 50°C to 60°C, and in summer it can reach as high as 80°C to 90°C. Traditional refrigerator compressors, due to sealing requirements and dust prevention needs, often suffer from poor heat dissipation, relying solely on transferring heat to the condenser for cooling. The refrigerator provides a small, enclosed space for the compressor, resulting in particularly poor heat dissipation and significant uncertainty in its operating conditions. The compressor casing temperature is high, with significant temperature differences between different parts, especially between the compression chamber and the air inlet. Generally, the air inlet area is relatively cooler, while the corresponding part of the compression chamber is relatively hotter, and the upper casing temperature is generally much higher than the lower casing temperature. This not only hinders the normal functioning of the equipment but also negatively impacts routine maintenance such as compressor lubrication. A common problem is high-temperature carbon buildup on the compressor cylinder head, leading to refrigeration cycle failure, refrigerator malfunctions, and a shortened compressor lifespan. Meanwhile, excessively high and uneven compressor temperatures prevent the refrigerant from dissipating heat in a timely manner, increasing compressor resistance, power consumption, and negatively impacting compressor lifespan. The inherent heat dissipation performance of traditional compressors is often overlooked.

[0004] In related technologies, please refer to Chinese Patent No. CN105464948B, which specifically discloses a device for enhancing the heat dissipation performance of a refrigerator compressor casing. When in use, this device dissipates heat from the compressor by providing heat dissipation fins on the upper casing of the compressor and by cooperating with heat pipes installed in the heat dissipation fins and on the outside of the upper casing of the compressor.

[0005] The applicant discovered a deficiency in the use of the aforementioned device for enhancing the heat dissipation performance of a refrigerator compressor casing: although heat dissipation fins are provided on the upper casing of the compressor and heat pipes are installed in the heat dissipation fins and on the outside of the upper casing of the compressor to dissipate heat, the heat dissipation structure is located on the outside of the compressor, which reduces the heat dissipation effect inside the compressor and affects the heat dissipation effect of the compressor.

[0006] In view of this, this technical solution proposes a high-efficiency heat dissipation refrigerator compressor housing, which can better solve the problems mentioned above.

[0007] Utility model content.

[0008] The technical solution adopted by this utility model is as follows: A high-efficiency heat dissipation refrigerator compressor housing, including a lower compressor housing and an upper compressor housing, the lower compressor housing and the upper compressor housing are connected to each other to form a sealed space, and are assembled into the outer housing of the compressor. The refrigerator compressor is installed at the lower end of the condenser. A rectangular heat dissipation fin is provided through the interior of the upper compressor housing for heat dissipation of the interior of the upper compressor housing.

[0009] The compressor housing shown has an annular heat sink on the top for heat dissipation. An mounting ring is fixedly installed inside the annular heat sink. A heat exhaust fan is installed inside the mounting ring for rapid heat dissipation. An integrated outer protective mounting body is connected through the compressor housing and the mounting ring. A second heat-conducting copper core is installed inside the outer protective mounting body for heat conduction inside the compressor housing.

[0010] In a preferred embodiment, a mounting base is provided at the lower end of the compressor lower housing, and the mounting base is provided with mounting holes inside.

[0011] In a preferred embodiment, the rectangular heat sink is linearly arranged inside and a first thermally conductive copper core is disposed through the rectangular heat sink to conduct heat to the inside of the compressor upper housing.

[0012] In a preferred embodiment, the inner side of the annular heat sink is provided with heat dissipation slots for heat dissipation, and the heat dissipation slots are distributed in a ring at equal intervals in the inner wall of the annular heat sink.

[0013] In a preferred embodiment, the outer protective mounting body, which is fixed in the mounting through hole inside the mounting ring, is located below the heat dissipation fan, and the outer protective mounting body is made of heat dissipation material.

[0014] In a preferred embodiment, both the compressor upper housing and the mounting ring have mounting through holes for installing an external protective mounting body, and the external protective mounting body is fixed in the mounting through hole to seal the mounting through hole.

[0015] In a preferred embodiment, the outer protective mounting bodies are arranged in a ring around the compressor housing and the mounting ring, and there are no fewer than eight outer protective mounting bodies.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: it facilitates faster heat dissipation from the lower and upper housings of the compressor, better protects the internal components of the lower and upper housings of the compressor from damage, and increases their service life.

[0017] 1. In this utility model, heat dissipation can be achieved by using a rectangular heat sink that penetrates the inside of the upper housing of the compressor, with a first heat-conducting copper core linearly arranged inside the rectangular heat sink.

[0018] 2. In this utility model, the annular heat sink and heat dissipation slot provided above the compressor upper housing can be used to dissipate heat above the compressor upper housing. An outer protective mounting body is installed through the mounting through hole opened inside the compressor upper housing and the mounting ring. At this time, the outer protective mounting body cooperates with the second heat-conducting copper core to dissipate heat inside the compressor lower housing and the compressor upper housing. At the same time, with the cooperation of the heat exhaust fan, the heat can be quickly discharged, increasing the heat dissipation efficiency inside the compressor lower housing and the compressor upper housing.

The interior of the rectangular heat sink 4 is linearly arranged, and a first heat-conducting copper core 5 is provided through the rectangular heat sink 4 for heat conduction inside the upper compressor housing 2.

[0028] refer to Figure 2-4As shown, the top of the compressor upper housing 2 is provided with an annular heat sink 6 for heat dissipation. The inner side of the annular heat sink 6 has heat dissipation slots 7, which are evenly distributed in a ring on the inner wall of the annular heat sink 6. A mounting ring 8 is fixedly installed above the inside of the annular heat sink 6. A heat exhaust fan 9 is installed above the inside of the mounting ring 8 for rapid heat dissipation. An integrated outer protective mounting body 11 connects the compressor upper housing 2 and the mounting ring 8, and a through hole 10 is fixed inside the mounting ring 8.
