Background
The intercooler is a matched set of the turbine-added engine, and has the functions of reducing the temperature of high-temperature air after the booster is used for boosting, reducing the heat load of the engine, improving the air inflow and increasing the power of the engine. Whether mechanically augmented or turbocharged, an intercooler is required to be installed between the supercharger and the intake manifold. The heat dissipation performance of the intercooler directly influences the power of the engine, so how to improve the heat dissipation performance of the intercooler becomes an important subject to be studied at present. At present, automobile manufacturers have own requirement indexes on the heat radiation performance of the intercooler, the conventional requirement is 60000 times, and even a high host factory is required to ensure that the heat radiation performance of the matched intercooler reaches more than 10 ten thousand times. The current situation of the intercooler is that the general heat radiation performance is low, the use requirement of customers cannot be met more and more, and the situation that whether the heat radiation performance of the intercooler is good or not becomes the bottleneck for improving the power of the turbocharged engine. Therefore, it is necessary to study the structure of the intercooler, and what factors affect the heat dissipation performance of the intercooler.
Structure of intercooler (as in fig. 1): the intercooler is composed of a main plate 2, a side plate 4, a radiating pipe 5, a core body of a radiating belt 6, a left air chamber 1, a right air chamber 1, a sealing gasket 3 and accessories, wherein a turbulent flow belt is arranged on the radiating pipe 5.
Through doing gas-gas intercooler pressure cycle test, products (taking a certain model of intercooler as an example) which are not up to standard in test are mostly undercut leakage, and sealing gasket overflow phenomenon, namely main piece biting teeth and the wall of a gas chamber are separated. Concluding that: the service lives of the main plate and the air chamber are not up to standard, so that the heat dissipation performance of the intercooler is not up to standard.
1) Air chamber: there are two factors that affect the strength of the air chamber: a. the material b of the air chamber, the air chamber reinforcing rib is related to the material c of the air chamber, the material used has good strength, hardness and pressure resistance; regarding the air chamber reinforcing ribs, the product is uniformly distributed with the reinforcing ribs, and the air chamber has better structural strength. So conclude that: the structural design of the air chamber influences the heat dissipation performance of the intercooler to a great extent.
2) Master slice: there are three factors affecting master strength: a. the main sheet material b is the main sheet material thickness c is the main sheet structure, and the heat radiation performance is not obviously improved after the improvement on the main sheet material and the material thickness. So conclude that: the structural design of the main plate influences the heat dissipation performance of the intercooler to a great extent.
Chinese patent CN204128402U discloses a vertical flow radiator for automobile, in which only one side of the end of the water chamber is fixed by the main plate, and the pressure of the air inlet is applied to the engagement teeth continuously to deform, that is, the engagement teeth of the main plate are separated from the air chamber wall, with the increase of the air cooling cycle number of the intercooler, and simultaneously, chinese patent CN205315104U discloses a water cooling radiator with an improved leakage-proof water chamber, in which, although both side surfaces of the end of the water chamber are fixed by the main plate, the inner side is inclined arc, and cannot provide high-strength supporting force, and the disengagement of the engagement teeth of the main plate and the air chamber wall is easy to occur after multiple air cooling cycles.
