Intake manifold of built-in intercooler

Abstract

The invention discloses an intake manifold of a built-in intercooler. The intake manifold comprises a manifold body and the intercooler. A pressure stabilizing cavity is formed in the manifold body, aflanging which extends outwards is arranged on the edge of the bottom of the intercooler, a circle of step face is arranged at the position, corresponding to the flanging of the intercooler, of the bottom of the pressure stabilizing cavity, a circle of small boss is arranged on the step face, multiple clamping jaws extending out towards the outer side of the intercooler are arranged on the two sides of the intercooler, and are in L shapes, the clamping jaws on each side are in group in pairs, the two sets of clamping jaws are opposite in direction, clamping grooves are formed in the positions, corresponding to the clamping jaws, of the two sides of the inner wall of the pressure stabilizing cavity, the cross sections of the clamping grooves are matched with the s clamping jaws in size, and the clamping grooves extend downwards from the top of the pressure stabilizing cavity. Through the above manner, the side mounting strength of the intercooler can be increased, the structure stability of the intercooler can be effectively kept, the product service life is prolonged, the material cost is reduced, the procedure of mounting the sealing ring is omitted, the total assembling time isshortened, and the production efficiency is indirectly improved.

Description

technical field [0001] The invention relates to the field of intake manifolds, in particular to an intake manifold with a built-in intercooler. Background technique [0002] The turbocharger is driven by the exhaust gas from the engine. The turbocharger is in a high temperature state, and the temperature of the intake air passing through the turbocharger will increase. Therefore, the turbocharged engine needs to use an intercooler to reduce the intake air temperature. , the intercooler is installed inside the intake manifold, since the intake air is in a state of high temperature and high pressure, the sealing performance between the intercooler and the intake manifold directly affects the cooling efficiency of the intake air; see figure 1 , the existing intercooler is equipped with a sealing ring along the lower part, and the intercooler is installed in the intake manifold to achieve a sealing effect, but the process of installing the sealing ring is cumbersome, which virtu...

[0002] The turbocharger is driven by the exhaust gas from the engine. The turbocharger is in a high temperature state, and the temperature of the intake air passing through the turbocharger will increase. Therefore, the turbocharged engine needs to use an intercooler to reduce the intake air temperature. , the intercooler is installed inside the intake manifold, since the intake air is in a state of high temperature and high pressure, the sealing performance between the intercooler and the intake manifold directly affects the cooling efficiency of the intake air; see figure 1 , the existing intercooler is equipped with a sealing ring along the lower part, and the intercooler is installed in the intake manifold to achieve a sealing effect, but the process of installing the sealing ring is cumbersome, which virtually reduces the production efficiency; Moreover, after the existing intercooler is installed in the intake manifold, if there is a gap between the core of the intercooler and the inner wall of the intake manifold, part of the intake air will enter the air passage through the gap and eventually cause the temperature of the horizontal bar to increase. The gap with the inner wall of the intake manifold is small enough. In the prior art, the intercooler is fixed inside the manifold by adding several through bolts, but there are the following disadvantages: the wind resistance of the air flowing through the intercooler is increased , reducing the effective heat dissipation area, reducing the working efficiency of the intercooler, increasing the number of accessories and assembly time, resulting in an increase in product manufacturing costs, additional mounting holes need to be opened on the manifold shell, resulting in increased leakage risk
