Problems solved by technology
[0004] According to the current intercooler development process, the trial production test requires a lot of manpower and material resources, and the cost is high
If the airflow uniformity of the intercooler structure designed for the first time is not good, because the specific parts that need to be optimized are not known, repeated attempts are required, which greatly increases the development cycle of the intercooler

Embodiment Construction
[0027] The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.
[0028] Such as Figure 1 to Figure 3 As shown, the present invention provides a kind of engine intercooler analysis method, comprises,
[0029] Step 1: Input the geometric model, and establish a preliminary three-dimensional data model of the intercooler according to the layout form and boundary conditions of the vehicle to be analyzed. In this application, the three-dimensional data model software uses NX or CATIA software; The data in the parts database should be borrowed from mature parts as far as possible, and under the premise of satisfying the boundary conditions of the whole vehicle, design 3-5 kinds of intercooler geometric mo...

The invention relates to an engine intercooler analyzing method. The method includes the steps of geometric model input and surface mesh and volume mesh division; boundary condition input and solver parameter setting; calculation and result evaluation and optimization design. An intercooler can be analyzed by the aid of computational hydrodynamics software. The intercooler is judged, optimized direction is provided for portions poor in air velocity uniformity and overlarge in pressure drop, and guidance is provided for optimization design of the intercooler. Multiple schemes of the intercooler can be analyzed to have the optimal scheme selected. With the method, manpower and material resources during design and development of the intercooler is greatly reduced, development period is shortened, and development efficiency is improved.
Description
technical field [0001] The invention belongs to the field of preparation methods of engine superchargers, and specifically refers to an analysis method of an engine intercooler. Background technique [0002] The supercharged intercooling system makes an important contribution to the power, economy and environmental protection of the engine. Therefore, it has been widely used in vehicle engines. Since the development of supercharged intercooler technology for vehicle engines started later than that of gasoline engines, a complete set of theories has not been formed for the design of intercoolers, and a unified standard for the evaluation methods of intercooler performance has not yet been formed. Therefore, in the development process of related intercooler products, it is often necessary to carry out a large number of matching tests on the whole machine, resulting in an increase in the development cycle and cost, which cannot meet the needs of supercharged intercooler applic...
