Novel intercooler main board

Abstract

The invention discloses a novel intercooler main board, which comprises a main board body (1), which is provided with a plurality of connecting through holes (2) for connecting the flat tubes of the intercooler. The main board body (1) is characterized in that the long side edge of the connecting through hole (2) of the plane of the main board body (1) has a right angle tipping edge (4) connected with the main board body (1), the opening of the right angle tipping edge (4) faces toward the inner direction of the main board body (1), and the wide edge of the connecting through hole (2) is the side wall plate of the main board body (1). The long-side side wall of the connecting through hole (2) and the flat tube of the intercooler are arranged for interference and squeezing. After the above structure is adopted, the through holes of the flat tubes are mounted to the inside of the main board body, so as to reduce the whole volume and make the main board light.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a novel intercooler main board. Background technique [0002] At present, turbocharged engines are widely used in the automotive industry. This is because the ventilation efficiency of turbocharged engines is higher than the natural intake of general engines, so turbocharged engines will have a larger air intake than ordinary engines. power. However, when the air enters the turbocharger, the temperature of the air will increase significantly, and the air density will decrease accordingly. After this uncooled high-temperature supercharged gas enters the combustion chamber of the engine, it will not only affect the charging efficiency of the engine In addition, it will also cause engine knocking or even damage and flameout due to the high air temperature. Therefore, it is necessary to set up an intercooler in the turbocharged engine system, which is commonly referred to as an ...

Problems solved by technology

[0004] 1) Since the base plate at the strip hole for installing the cooling pipe is provided with circular right-angle flanges, these right-angle flanges are all flanged toward the outside of the main board, therefore, the height of the entire main board is determined by the main board body The sum of the height of the flange and the height of the right-angled flange increases the overall volume of the main board; however, in order to ensure the connection between the cooling pipe and the main board, the height of the flange must reach the design value, therefore, the height of the flange cannot be shortened way to reduce the overall volume of the motherboard;

[0005] 2) Furthermore, due to the increase in the volume of the main board, the material weight of the overall main board is also increased. At present, with the development of lightweight automobiles, there are also requirements for weight reduction, lightening and performance improvement of the component structure. Therefore, the current The technical motherboard structure can no longer meet this lightweight demand
