Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0017] As shown in the attached Figure 1 to the attached Figure 2 figure.
[0018] An energy-saving pipeline assembly for a new energy vehicle air conditioner provided by the utility model comprises an air conditioner low-pressure pipe 1, an air conditioner high-pressure pipe 2, a pipeline parallel connection bracket 3, a low-pressure inspection hole 4, a high-pressure inspection hole 5 and a vehicle body mounting bracket 6, wherein: one end of the air conditioner low-pressure pipe 1 is connected to the outlet of the evaporator, and the other end is connected to the inlet of the expansion valve; one end of one of the air conditioner high-pressure pipes 2 is connected to the outlet of the compressor, and the other end is connected to the inlet of the radiator; one end of the other air conditioner high-pressure pipe 2 is connected to the outlet of the radiator, and the other end is connected to the inlet of the expansion valve, and a dryer is connected in the middle; the pipeline parallel connection bracket 3 is fixedly installed between the air conditioner low-pressure pipe 1 and the air conditioner high-pressure pipe 2, and the low-pressure inspection hole 4 and the high-pressure inspection hole 5 are respectively installed on the air conditioner low-pressure pipe 1 and the air conditioner high-pressure pipe 2; the vehicle body mounting bracket 6 is fixedly installed on the air conditioner low-pressure pipe 1 and the air conditioner high-pressure pipe 2 and is connected and fixed to the vehicle body.
[0019] The air conditioner high-pressure pipe 2 comprises a pipe main body 21, an outer protective shell 22, an internal pressure-resistant structure 23 and a pressure-resistant rib 24, and the outer protective shell 22 is fixedly installed on the outside of the pipe main body 21, and the internal pressure-resistant structure 23 is fixedly installed on the inner wall of the pipe main body 21; both ends of the pressure-resistant rib 24 are fixedly installed on the inner wall of the internal pressure-resistant structure 23.
[0020] The energy-saving pipeline assembly for a new energy vehicle air conditioner is mainly composed of an air conditioner low-pressure pipe 1, an air conditioner high-pressure pipe 2, a pipeline parallel connection bracket 3, a low-pressure inspection hole 4, a high-pressure inspection hole 5 and a vehicle body mounting bracket 6. Its working principle is as follows:
[0021] 1. Refrigerant circulation process
[0022] The refrigerant enters the air conditioner high-pressure pipe 2 in a high-pressure gaseous form from the outlet of the compressor and is transmitted to the radiator through the high-pressure pipe. In the radiator, the refrigerant releases heat and condenses into a high-pressure liquid state. Then, the refrigerant passes through the dryer to further remove impurities and moisture, and then continues to be transmitted to the inlet of the expansion valve through the air conditioner high-pressure pipe 2.
[0023] In the expansion valve, the pressure of the refrigerant drops rapidly and becomes a low-pressure gaseous state. The low-pressure gaseous refrigerant is transmitted back to the evaporator through the air conditioner low-pressure pipe 1, absorbs heat and vaporizes in the evaporator, and becomes a low-pressure gaseous refrigerant again, completing a refrigeration cycle.
[0024] 2. Pressure-resistant design of the high-pressure pipe
[0025] In order to ensure the safety and stability of the high-pressure refrigerant during transmission, the high-pressure pipe 2 is designed with a multi-layer pressure-resistant structure:
[0026] Pipe main body 21: Made of stainless steel, it provides basic pressure resistance and structural strength.
[0027] Outer protective shell 22: An additional protective layer is added to provide heat insulation and further enhance the compressive resistance.
[0028] Internal compressive structure 23: It is arranged on the inner wall of the pipeline main body to further increase the internal supporting force of the pipeline.
[0029] Compressive ribs 24: They are evenly distributed inside the internal compressive structure to enhance the overall compressive performance of the pipeline and ensure that it will not deform or rupture under high-pressure environments.
[0030] 3. Fixing and supporting of the pipeline
[0031] The vehicle body mounting bracket 6 fixes the air-conditioning low-pressure pipe 1 and the air-conditioning high-pressure pipe 2 inside the vehicle body through bolts. The mounting brackets are evenly distributed at various positions of the pipeline, effectively reducing the vibration and stress brought by vehicle driving to the pipeline and preventing the pipeline from loosening or being damaged. The planar design of the mounting bracket allows the installation of extension brackets on its surface, increasing the flexibility and adaptability of pipeline layout.
[0032] 4. Inspection and maintenance
[0033] The air-conditioning low-pressure pipe 1 and the air-conditioning high-pressure pipe 2 are respectively provided with a low-pressure inspection hole 4 and a high-pressure inspection hole 5, which are convenient for inspecting and maintaining the pipeline. Through these inspection holes, it is convenient to supplement the refrigerant, detect leaks and monitor the pressure, ensuring that the system operates in the best state.
[0034] Summary
[0035] The energy-saving pipeline assembly for new energy vehicle air conditioners ensures the safe, stable and efficient operation of the air-conditioning system under high-pressure environments through efficient refrigerant circulation, strict compressive design and reliable fixing and support. Its reasonable structural design and convenient inspection function make the system have significant energy-saving effects and reliability in practical applications.
