Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of compressor heat dissipation, in particular to a gravity heat dissipation plate with controllable heat dissipation capacity. Background Art
[0002] Due to the wide application of frequency conversion technology in refrigerators and air conditioners, in the field of air conditioning, the application of frequency conversion technology enables air conditioners to adjust their cooling or heating capabilities in real time according to changes in indoor temperature, achieving more accurate temperature control. At the same time, frequency conversion air conditioners can maintain stable power output during operation, avoiding the energy consumption and noise problems caused by the frequent start-up of traditional air conditioners. In addition, frequency conversion air conditioners perform well in energy saving, and can save a lot of electricity and reduce the cost of use compared to traditional air conditioners. The application of frequency conversion technology in household appliances has undoubtedly brought many conveniences to modern life.
[0003] The control of the host refrigeration and heating system by frequency conversion technology is mainly reflected in the control of the compressor, because the compressor is an important component in the refrigerator and air conditioning system. Taking air conditioning as an example, the commonly used working modes are cooling and heating.
[0004] Cooling mode: In summer, when the weather is hot and the temperature is high, the compressor temperature of the air conditioner is usually relatively high when it is turned on. In some high-temperature areas, the compressor startup temperature can be close to 90°. Especially when the compressor is working, a large amount of heat will be generated inside. This heat needs to be released in time. If the heat is not dissipated in time, it will cause the temperature to be too high and the cooling effect to be poor, affecting the normal operation of the machine and even damaging the equipment.
[0005] Heating mode: In winter, when the weather is cold and severe, starting the heating mode will make the compressor difficult and slow to start due to environmental influences, resulting in increased energy consumption; in a low temperature environment, long-term operation will not only increase energy consumption, but also increase the load on the compressor, thereby shortening the service life of the compressor.
[0006] With the advancement of technology, people's demand for the comfort of smart home appliances is getting higher and higher, especially refrigerators and air conditioners are becoming more and more intelligent, which means that the reliability requirements for compressors are also getting higher and higher. Therefore, improving the reliability of compressors is an important direction for future development; how to solve the problems that arise in compressors under the above-mentioned extreme conditions is also imminent and needs to be solved urgently.

The device does not require additional power during operation, meets the requirements of green environmental protection and energy saving, and can effectively solve the problems in the background technology.
[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gravity heat sink with controllable heat dissipation capacity, comprising a heat sink, a heat dissipation blowing plate is provided on one side of the heat sink, a heated evaporation zone and a cooling zone are formed between the heat dissipation blowing plate and the heat sink, the heated evaporation zone is located below the cooling zone, a filling port for filling refrigerant into the heated cooling zone is provided on the upper end of one side between the heat dissipation blowing plate and the heat sink, a gas one-way flow pipeline is provided between the upper end of one side of the evaporation zone and the upper end of one side of the cooling zone, and the lower end of the other side of the evaporation zone is connected to the lower end of the other side of the cooling zone through a liquid flow channel, and a solenoid valve is connected in series on the liquid flow channel.
[0009] Furthermore, the four corners of the heat sink are provided with mounting through holes, and the area of the heat sink corresponding to the heated cooling area is fitted with the external heat sink.

[0011] Furthermore, the gas unidirectional flow pipeline is provided with blocking bumps on the left and right sides, the blocking bumps on the left and right sides are spaced apart, and the blocking bumps are water drop-shaped structures. The blocking bumps with water drop-shaped structures can block the fluid in the heated evaporation zone from flowing to the cooling zone.
[0012] Furthermore, guide baffles are provided on both sides of the heated evaporation zone, the guide baffles are spaced apart on the left and right sides, and the guide baffles are all inclined. The inclined guide baffles can make the gas flow in an S-shaped channel, thereby achieving a better cooling effect of the gas refrigerant.
[0013] Furthermore, heat dissipation fins are evenly arranged on one side of the heat dissipation plate, and the heat dissipation fins correspond to the cooling zone. The heat dissipation effect of the cooling zone is better through the heat dissipation fins, so that the gas refrigerant inside the cooling zone is quickly cooled into liquid.
[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: a gravity heat pipe radiator is formed by welding, sealing and injecting refrigerant into the heat dissipation plate, which can be bent and rolled as needed and installed outside the compressor housing.
