Abstract

The utility model discloses an automobile intercooler air chamber. A separation plate is arranged in an upper air chamber of an intercooler and divides the air chamber into an air inlet cavity and an air outlet cavity. Long-battlement-shaped openings are formed in the end portion of the separation plate in the air chamber, guide bars are arranged in the air inlet cavity and the air outlet cavity of the air chamber respectively, the long-battlement-shaped openings in the end portion of the separation plate enable air flow of the air inlet cavity and the air flow of the air outlet cavity to be exchanged mutually, the temperature difference of cooling pipes on the two sides of the separation plate of the upper air chamber is lowered, the cooling pipes on the two sides of the separation plate are prevented from generating hot stress, and the breakage mode of the cooling pipes is effectively reduced. Air flow in the cavities of the air chamber is made to be reasonably distributed through the guide bars, and heat radiation is facilitated. The overall strength of the upper air chamber is enhanced through the guide bars, the amplitude of the reciprocating motion of a core main sheet is reduced, and therefore the main sheet is prevented from being broken off.

Description

A kind of charge air cooler air chamber

Technical field

The utility model belongs to vehicle intercooler technical field, relates to a kind of charge air cooler air chamber, is specially adapted to " U " type flow structure charge air cooler.

Background technology

Existing " U " type flow structure charge air cooler comprises a core body and upper chamber, lower chamber, and upper chamber, lower chamber are connected with core body two ends respectively, and air inlet, gas outlet are positioned at upper chamber, in the middle of upper chamber, has dividing plate that inlet chamber, outlet chamber are separated.

During charge air cooler work, high temperature and high pressure gas enters from upper chamber air inlet core body one side of flowing through, and then enters lower chamber air cavity, then the opposite side of the core body of flowing through, and finally by upper chamber gas outlet, is flowed out.Temperature difference into and out of air cavity surpasses more than 100 ℃, easily causes the cooling tube of close upper chamber dividing plate both sides because existing thermal stress to rupture; And the continuous pulsed of high temperature and high pressure gas is impacted upper chamber, makes the continuous Swelling and contraction of air chamber, drive the main leaf of core body to move reciprocatingly, easily make main leaf produce jackknifing.

Summary of the invention

The utility model discloses a kind of vehicle intercooler air chamber, to solve in prior art near the problem of the main leaf jackknifing of the fracture of the cooling tube of core body and core body upper chamber dividing plate.

A kind of vehicle intercooler air chamber of the utility model, has dividing plate, and air chamber is separated into inlet chamber, outlet chamber; It is characterized in that: the dividing plate end in air chamber has the gap of Great Wall buttress shape, the air-flow of inlet chamber, outlet chamber is exchanged mutually, reduce the cooling tube temperature difference of upper chamber dividing plate both sides, avoid the cooling tube of dividing plate both sides to produce thermal stress, effectively reduce the generation of cooling tube fracture mode.

The disclosed a kind of charge air cooler air chamber of the utility model, be further characterized in that: in air chamber inlet chamber, outlet chamber, respectively have a guiding rib, the size of guiding rib and layout can be according to the position of air chamber inlet, outlet and aerodynamic design, air-flow in air chamber is reasonably distributed, be conducive to heat radiation.Guiding rib has been strengthened the bulk strength of upper chamber, reduces the reciprocating amplitude of core body main piece, thereby avoids the fracture generation of phenomenon of main leaf.

The utility model air chamber is charge air cooler upper chamber.

Good effect of the present utility model is: reduced the generation of cooling tube fracture mode, avoided the fracture generation of phenomenon of main leaf; Be particularly useful for " U " type flow structure charge air cooler.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model front view;

Fig. 3 is the utility model upward view;

Fig. 4 is that the utility model charge air cooler is installed connection diagram;

In figure: 1 upper chamber, 2 core bodys, 3 cooling tubes, 4 main leaves, 5 lower chambers; Wherein: 1a dividing plate, 1b guiding rib, 1c gas outlet, 1d air inlet.

The specific embodiment

The utility model is as shown in Figure 4: vehicle intercooler comprises upper chamber 1, core body 2, cooling tube 3, main leaf 4, lower chamber 5; Core body 2, cooling tube 3, main leaf 4 are arranged between upper chamber 1 and lower chamber 5.

As shown in Figure 1, Figure 2, Figure 3, Figure 4: in upper chamber 1, there is dividing plate 1a, upper chamber 1 is separated into inlet chamber, outlet chamber.In upper chamber inlet chamber, outlet chamber, respectively there is a guiding rib 1b, guiding rib is reasonably distributed air-flow in air chamber, is conducive to heat radiation, and has strengthened the bulk strength of upper chamber 1, reduce the reciprocating amplitude of core body main piece 4, thereby avoid main leaf 4 to fracture.

As shown in Figure 1: in upper chamber, 1 dividing plate 1a end has the gap of Great Wall buttress shape, the air-flow of inlet chamber, outlet chamber is exchanged mutually, reduce cooling tube 3 temperature difference of upper chamber dividing plate both sides, avoid the cooling tube 3 of dividing plate 1a both sides to produce thermal stress, effectively reduce cooling tube 3 fractures and occur.

Claims

1. a charge air cooler air chamber, its inside has dividing plate, and air chamber is separated into inlet chamber, outlet chamber; It is characterized in that: the dividing plate end in air chamber has the gap of Great Wall buttress shape.

2. a kind of charge air cooler air chamber according to claim 1, is characterized in that: in air chamber inlet chamber, outlet chamber, respectively have a guiding rib.
