Description

A new intercooler

technical field

The utility model relates to an intercooler, in particular to a novel intercooler for automobile engines.

Background technique

At present, there are two main types of supercharged intercoolers used in automobile engines: air-cooled intercoolers and water-cooled intercoolers. Due to the complex structure and high cost of the cooling water cooling method, and the cooling effect is not good, the temperature after cooling is still maintained at about 70°C, so the external air cooling method is mainly used at present, that is, the external air is used to cool the turbocharger. High temperature and high pressure gas. The core body of the traditional intercooler is a plate-fin welded structure. A layer of corrugated plates is stacked up and down with aluminum alloy plates, and sealing strips are installed at the front and back to form hot air flow channels. Most of the fins are corrugated fins, but this kind of intercooler has the disadvantages of heavy weight, poor heat dissipation performance and large air resistance.

Utility model content

The technical problem to be solved by the utility model is to provide a new type of intercooler for the problem of poor heat dissipation caused by the prior art, so as to effectively improve the cooling performance during use.

In order to solve the above-mentioned technical problems, the technical proposal of the utility model is that a new intercooler includes an air inlet chamber and an air outlet chamber, a heat dissipation system is arranged between the air inlet chamber and the air outlet chamber, and an upper cover is arranged inside the heat dissipation system plate and the lower cover plate, between the upper and lower cover plates there are multi-layer heat dissipation modules and heat dissipation pipes that can promote the heat exchange between the indoor air and the outside air, and a number of serrated heat dissipation fins protrude from the interior of the heat dissipation module. The radial section of the heat dissipation pipe is elliptical, and the heat dissipation modules and heat dissipation pipes are alternately arranged.

Due to the above-mentioned special structure of the new intercooler, it can effectively improve the cooling performance of the intercooler during long-term use, thereby having obvious benefits in improving engine power and reducing emissions.

Detailed ways

Figure 1 is a structural schematic diagram of a new type of intercooler. The new intercooler includes an air intake chamber 1 and an air outlet chamber 5, wherein a heat dissipation system is provided between the air intake chamber 1 and the air outlet chamber 5, and an upper cover plate 6 and a lower cover plate 7 are arranged inside the heat dissipation system, and the upper cover A heat dissipation module 2 and a heat dissipation pipe 4 that can promote heat exchange between the indoor air and the outside air are arranged between the plate 6 and the lower cover plate 7. There are serrated heat sinks 3 protruding from the inside of the heat dissipation module 2. Due to these serrated Shaped heat sink 3, thereby increasing the heat dissipation area of the gas, improving the heat dissipation effect, and also conducive to the flow of outside air, and at the same time slowing down the eddy current formed between the heat sink 3, so that the flow of air becomes a forced turbulent flow , which in turn improves the cooling performance of the intercooler; the radial section of the cooling pipe 4 is elliptical. When the gas flow rate is the same, the elliptical structure has the largest heat dissipation area, and can also strengthen the overall strength of the intercooler. The heat dissipation module 2 and radiating pipes 4 are alternately arranged. When working, the high-temperature and high-pressure air from the turbocharger first enters the air intake chamber 1, flows through the heat dissipation pipe 4, and enters the air outlet chamber 5 at the other end after sufficient gas exchange, and flows out of the air outlet, thus completing the entire heating process. exchange process.

The structural diagram of the heat dissipation module shown in Figure 2, a number of serrated heat dissipation fins 3 protrude from the interior of the heat dissipation module 2, due to the presence of these serrated heat dissipation fins 3, the heat dissipation area of the gas is increased, the heat dissipation effect is improved, and the heat dissipation effect is also improved. It is beneficial to the flow of outside air, and at the same time, it can slow down the eddy current formed between the cooling fins, so that the flow of air becomes a forced turbulent flow, thereby improving the cooling performance of the intercooler.

From the combination of Figure 1 and Figure 2, because the new intercooler has the above-mentioned special mechanism, it can be seen through analysis that the heat dissipation area of the new intercooler is increased by more than 15% compared with the original intercooler, and the optimized cooling method promotes The improvement of the cooling performance of the intercooler, a large number of sawtooth fins integrated in the heat dissipation module greatly increase the heat dissipation area, improve the cooling performance, and have great significance for improving engine power and reducing emissions; the heat dissipation structure composed of many heat dissipation modules is flexible , Easy assembly and strong interchangeability.

Of course, the shape of the heat sink is not limited to sawtooth, but also other effective shapes, and the shape of the heat pipe is not limited to an elliptical radial section, but can also be other suitable shapes such as circle, square, etc. Such transformations all fall within the protection scope of the present utility model.
