Description

Technical Field

[0001] This utility model belongs to the field of automotive air conditioning system component manufacturing technology, and in particular relates to a B-dimensional gauge for the refrigerant circulation pipeline from the refrigerator to the compressor. Background Technology

[0002] The automotive air conditioning system consists of heating, cooling, air purification, and control systems. The cooling system comprises a refrigerant (evaporator), compressor, condenser, expansion valve, receiver-drier, and connected high and low pressure refrigerant circulation lines. Its main function is to regulate and control the temperature and humidity of the air entering the vehicle cabin from either the interior or exterior. The circulating refrigerant within the system exchanges heat through the refrigerant (evaporator) and condenser, absorbing and dissipating heat from the air passing through the cabin, thus providing a comfortable driving and passenger environment.

[0003] The flexible low-pressure pipe assembly for heavy-duty truck air conditioning—from the refrigerant to the compressor B—is a key component of a heavy-duty truck air conditioning refrigeration system. It is the low-pressure pipeline component connecting the refrigerant to the compressor in the refrigeration system. Due to the different installation locations of the refrigerant (evaporator), condenser, expansion valve, and compressor in automotive air conditioning systems, and the space constraints, the refrigerant circulation pipelines connecting them are extremely tortuous and complex. Therefore, the designed pipeline routes are also varied and winding. Using conventional measuring tools to inspect dimensions during the manufacturing process presents many difficulties, making it hard to guarantee product consistency and dimensional accuracy, and is also very time-consuming, affecting the product's production schedule.

It has the advantages of significantly shortening the inspection time for the full size of the product, ensuring measurement accuracy and precision, guaranteeing the measurement consistency and product consistency of batch products, and completing the full size inspection and measurement of the product in one go. It also has the advantages of simple and reliable structure and convenient operation. It solves the problems of long inspection and measurement time, poor detection accuracy, precision and consistency of existing conventional measuring tools, which affect the inspection efficiency and production progress.

[0005] This utility model is implemented as follows: a dimensional gauge for the refrigerant circulation pipeline B from the refrigerator to the compressor, comprising a base plate and a refrigerant circulation pipeline B body.

[0010] As a preferred embodiment of this utility model, the top of the measuring tube on the side of the cooler is fixedly installed with a pressure plate cover by hexagonal bolts.
