Description

Water-air intercooler using novel air chamber structure

Technical Field

The utility model belongs to the technical field of car water air cooler technique and specifically relates to an use water air cooler of novel air chamber structure.

Background

In the modern society, the automobile age is rapidly developed, and an intercooler can be seen only in a vehicle provided with a turbo charger. The intercooler is generally made by aluminum alloy material, according to cooling medium's difference, common intercooler can be divided into two kinds: one is that the temperature is reduced by cold air which is collided into the vehicle from the head to the face when the vehicle runs, namely the air cooling is carried out; another approach, just opposite to air cooling, is to place a cooler, whose shape and principle are substantially identical to those of an air-cooled intercooler, into the intake duct, and let the pressurized hot air flow through. The cooler has cooling water flowing continuously to take away the heat of the pressurized air, i.e. water cooling.

The intercooler functions as follows:

(1) the temperature of the exhaust gas from the engine is very high and the temperature of the intake air is increased by heat conduction through the supercharger. Furthermore, the density of the air increases during compression, which necessarily also results in an increase in the temperature of the air, thereby affecting the charging efficiency of the engine. If further improvement in charging efficiency is desired, the intake air temperature is lowered. Data show that under the same air-fuel ratio condition, the engine power can be improved by 3-5% when the temperature of the pressurized air is reduced by 10 ℃.

(2) If uncooled charge air enters the combustion chamber, besides affecting the charging efficiency of the engine, the charge air is easy to cause the combustion temperature of the engine to be too high, causing faults such as knocking and the like, and increasing the content of NOx in the exhaust gas of the engine to cause air pollution. In order to solve the adverse effect that the air intensification after the pressure boost caused, consequently need install the intercooler additional and reduce the intake air temperature. The water-air intercooler uses water as a cooling medium, is mainly used for cooling the pressurized air of engines of vehicles, ships, generator sets and the like, belongs to an energy-saving and environment-friendly product, and is beneficial to increasing power and reducing good emission.

After the air chamber structure is matched with the sealing gasket and pressed with the core body, the sealing performance is very important. And the seal structure design among the prior art is unreasonable, leads to intercooler product quality to descend, in process of production, has the leakage problem. And cannot bear certain pressure when in use, the air chamber is easy to separate from the core body, thereby affecting the performance of the engine, and the following defects exist:

1. the structure of the air chamber is limited to argon arc welding, and professional personnel are required to operate, weld and process. The labor cost is high;

2. the requirement on air chamber parts is high, and the requirement on an air chamber mould is high;

3. in a limited space, the performance of the intercooler cannot be improved;

4. if the repaired piece is almost difficult to repair, the repaired piece is scrapped.
