Description

Technical Field

[0001] The utility model relates to the technical field of cooling equipment, in particular to a safety control and protection device for vehicle cooling equipment. Background Art

[0002] The driving cooling device is a device installed inside the vehicle to reduce the temperature inside the vehicle and provide a cool and comfortable environment. It achieves the cooling effect through a series of technologies and components working together. Its core principle is usually to use the physical changes of the refrigerant, that is, the cycle of compression, condensation, expansion and evaporation to absorb the heat inside the vehicle and discharge it outside the vehicle. Specifically, the compressor compresses the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas, and then cools the high-temperature and high-pressure gas into a high-temperature and high-pressure liquid through heat exchange with the outside air in the condenser. Then, the refrigerant is reduced in pressure through the expansion valve and becomes a low-temperature and low-pressure liquid that enters the evaporator. In the evaporator, the low-temperature and low-pressure refrigerant liquid absorbs the heat inside the vehicle and evaporates into a low-temperature and low-pressure gas, thereby achieving cooling inside the vehicle.

[0003] The driving cooling air equipment is a device designed to provide cooling function for the internal environment of the vehicle. It usually consists of the following main parts: Compressor: It is the core component of the refrigeration cycle, responsible for compressing and transporting refrigerant. Condenser: Cools and condenses the high-temperature and high-pressure refrigerant gas into liquid. Evaporator: The low-temperature liquid refrigerant evaporates here to absorb heat and reduce the air temperature in the car. Expansion valve: Controls the flow and pressure of the refrigerant so that it enters the evaporator. The driving cooling air equipment has the following characteristics: Adapt to vehicle working conditions: It can withstand complex conditions such as vibration, bumps and temperature changes during vehicle driving. Rapid cooling: Reduce the temperature in the car in a short time to provide a comfortable environment for drivers and passengers. Energy saving and high efficiency: The design focuses on reducing energy consumption to reduce the consumption of fuel or electricity in the vehicle. Compact size: It can be installed in the limited space in the car without affecting the overall layout and use of the vehicle.

[0004] During the use of existing vehicle cooling equipment, refrigerant needs to be added to ensure the operation of the equipment. However, during the operation of the equipment, changes in environmental temperature can easily cause the refrigerant inside the refrigerant storage tank to damage the refrigerant storage tank due to changes in pressure, causing environmental pollution and affecting the refrigeration performance. In addition, when the pipes in the refrigeration system change in pressure, they can easily be damaged. Utility Model Content

During the process of workers adding refrigerant, when refrigerant is added to the refrigerant storage tank 1, when the stored pressure exceeds the stored pressure, the excess refrigerant overflows into the pressure-maintaining tank 3 through the refrigerant transmission pipe 2, and at the same time, the excess refrigerant pushes the pressure-maintaining piston 5 to move. When a certain amount of refrigerant is used, the excess refrigerant is pushed by the pressure-maintaining spring 4 to push the refrigerant in the pressure-maintaining tank 3 back to the refrigerant storage tank 1 through the pressure-maintaining piston 5.

[0030] Reference Figure 1-Figure 2 A pressure tube 9 is fixedly connected to the middle of the left end of the outer side of the refrigerant storage tank 1, a pressure stabilizing seat 10 is fixedly connected to the left end of the pressure tube 9, a pressure stabilizing tube 11 is fixedly connected to the top of the pressure stabilizing seat 10, a pressure stabilizing tube 11 is arranged at the top of the pressure stabilizing tube 11, and a pressure stabilizing rubber 13 is arranged in the middle between the pressure stabilizing tube 11 and the pressure stabilizing cover 14. When the cold air equipment starts to run, the compressed gas in the pressure tube 9 passes through, in order to ensure the stable operation of the pipeline, when the pipeline pressure increases, the excessive pressure will lift up the pressure stabilizing rubber 13, and when the pressure in the pipeline drops, the pressure stabilizing rubber 13 will stabilize the pressure of the compressed gas and keep the pressure in the pipeline stable.

[0031] Reference Figure 1-Figure 2 The four corners of the bottom of the refrigerant storage tank 1 are fixedly connected to the tank body bracket 22, the left and right sides of the outer ring bottom of the pressure-maintaining tank 3 are fixedly connected to the pressure-maintaining bracket 19, the left and right sides of the bottom of the pressure-maintaining tube 11 are fixedly connected to the pressure-maintaining bracket 20, the outer top of the pressure-maintaining tube 11 is fixedly connected to the pressure-maintaining flange 12, the outer bottom of the pressure-maintaining cover 14 is fixedly connected to the pressure-maintaining flange 12, the outer ring of the top of the pressure-maintaining flange 12 is equidistantly provided with bolt holes 18, the middle of the inner side of the bolt hole 18 is provided with a fixing bolt 16, and the outer bottom of the fixing bolt 16 is fixedly provided with a fixing bolt 16.

When the pressure-stabilizing film 13 is used for a long time, it needs maintenance. At this time, the workers only need to loosen the fixing bolts 16 and the fixing nuts 17, remove the pressure-stabilizing cover 14, replace the pressure-stabilizing film 13, and then tighten the fixing bolts 16 and the fixing nuts 17.

[0032] Working principle: During the process of workers adding refrigerant, when the refrigerant is added to the refrigerant storage tank 1, when the storage pressure exceeds the storage pressure, the excess refrigerant overflows into the pressure maintaining tank 3 through the refrigerant transmission pipe 2. At the same time, the excess refrigerant pushes the pressure maintaining piston 5 to move. After a certain amount of refrigerant is used, the excess refrigerant is pushed by the pressure maintaining spring 4 to push the refrigerant in the pressure maintaining tank 3 back to the refrigerant storage tank 1 through the pressure maintaining piston 5. When the cold air equipment starts to run, the compressed gas in the pressure pipe 9 passes through. In order to ensure the stable operation of the pipeline, when the pipeline pressure increases, the excessive pressure will lift the pressure stabilizing film 13. When the pressure in the pipeline drops, the pressure stabilizing film 13 stabilizes the pressure of the compressed gas and keeps the pressure in the pipeline stable. After the pressure stabilizing film 13 has been used for a long time, maintenance is required. At this time, the worker only needs to loosen the fixing bolts 16 and the fixing nuts 17, remove the pressure stabilizing cover 14, replace the pressure stabilizing film 13, and then tighten the fixing bolts 16 and the fixing nuts 17.
