Description

Connecting pipeline of intercooler and vehicle

Technical Field

The utility model relates to an intercooler part, in particular to a connecting pipeline of an intercooler and a vehicle.

Background

The intercooler air inlet and outlet pipe is one of important component parts for conducting high-pressure gas into the engine, so that reasonable arrangement of the intercooler pipeline is very important, and safety and performance of the intercooler can be influenced.

Because the length of the air inlet and outlet pipe of the intercooler is long, and can reach about one meter in some cases, the installation and arrangement modes of the intercooler are difficult, and certain sacrifice and yield are needed in cost and convenience in many cases to finish normal assembly. Meanwhile, the working condition of the air inlet and outlet pipeline of the intercooler is often harsh, and high-pressure or high-temperature and high-pressure working conditions exist, so that the air inlet and outlet pipeline of the intercooler is required to have enough structural strength to meet the conventional gas conveying function besides meeting the assembly requirement, and is often difficult to work.

The arrangement scheme of connecting pipelines (charge air cooler air inlet and outlet pipes) of the traditional charge air cooler is characterized in that clamping connection is achieved by adopting clamping clamps at two ends, so that clamping clamp bolt heads are required to be tightened by adopting additional installation tools, operation is difficult to achieve in some small spaces, and the problems of difficult installation and high cost exist. Some schemes adopt a quick connector to quickly complete connection, but the scheme realizes distance contraction through the material flexibility of a rubber tube when the quick connector is installed on an intercooler, and has high cost, poor environmental protection and heavy weight.

For example, chinese patent CN209724542U discloses an air outlet pipe of an intercooler, which comprises a reducing rubber pipe, a vibration isolation rubber pipe and a hard pipe joint for connecting the reducing rubber pipe and the vibration isolation rubber pipe; the reducing rubber tube comprises a first straight tube connected with the hard tube joint and a round platform tube with one end connected with the throttle body, and the inner diameter of the first straight tube is larger than or smaller than that of one end of the round platform tube. The corrugated pipe is used as the vibration isolation rubber pipe in the pipeline proposed in the patent, and the metal ring is arranged, so that the compression resistance is improved, the vibration isolation rubber pipe is ensured not to deform, and the distance shrinkage is realized through the flexibility of the rubber pipe material in the process of assembling the pipeline onto the intercooler, so that the pipeline is high in cost and not friendly to the environment.

Thermoplastic elastomers TPE/TPR, also known as elastomers or synthetic rubbers. The product has the excellent performances of high elasticity, ageing resistance and oil resistance of the traditional crosslinked vulcanized rubber, and has the characteristics of convenience in processing and wide processing modes of common plastics, and can be produced by adopting the processing modes of injection molding, extrusion, blow molding and the like. However, the heat resistance is inferior to that of conventional rubber, and the physical properties are greatly reduced with the increase of temperature, so that the application range is limited. For the connecting pipeline of the intercooler, the thermoplastic elastomer material needs to ensure flexibility and enough rigidity, and the thin-wall corrugation is not broken or failed by the pulse gas with high temperature and high pressure, so that relevant contents are fresh in the prior art.

Therefore, the utility model provides a structure of a connecting pipeline of an intercooler, which aims to solve the problem that a thermoplastic elastomer is difficult to apply in the connecting pipeline of the intercooler.

Example 1

The connecting pipeline of the intercooler, as shown in figures 2 and 3, comprises a connecting pipe 1, wherein a first end of the connecting pipe 1 is connected with an engine interface through a rubber pipe 2, and a second end of the connecting pipe is connected with a male joint of the intercooler;

One of the differences from the conventional intercooler air inlet and outlet pipeline is that the connecting pipe 1 is integrally formed with a section of blow molding corrugated pipe 3 at one end close to the quick connector by blow molding, and the corrugated pipe 3 is made of heat-shrinkable elastomer material by blow molding and can have a certain shrinkage. The heat-shrinkable elastomer material adopted by the corrugated pipe 3 is preferably PA6, PA6+GF15, TPV (PP +EPDM), PP, PPGF15, TPEE (TEEE) and other materials, and has enough pressure bearing and temperature resistance on the basis of ensuring certain shrinkage capacity. Because this connecting pipe 1 adopts blowing integrated into one piece with bellows 3, still saved a plurality of connection interfaces in comparison with traditional connection structure, reduce revealing or the risk of damaging to manufacturing cost has been reduced.

As shown in fig. 3, the distance L from the first fixing seat 4 on the connecting pipe 1 to one end of the intercooler male connector is controlled to be less than 500mm, so that enough allowance space is provided for arrangement of automobile assembly, and unnecessary space occupation is reduced; meanwhile, the shrinkage of the corrugated pipe 3 is about 30+/-10 mm so as to meet the shrinkage required to be met when the quick connector and the intercooler male connector are assembled in a limited space.

In addition, the connecting pipeline is different from the traditional intercooler air inlet and outlet pipe in that the first fixing seat 4 and the second fixing seat 5 on the connecting pipe 1 are fixedly connected with the automobile body, so that the traditional fixing on the engine is replaced, the fixing is ensured to be more firm, and the damage to the engine can be avoided.
