Intercooler of turbocharger

Abstract

The invention discloses an intercooler of a turbocharger. The intercooler comprises a shell body and heat exchange tubes, two partition plates are arranged in a containing cavity, the partition plates are matched with the shell body in shape and is in sealed connection with the shell body; a liquid inlet and a liquid outlet are formed in the position, corresponding to a heat exchange chamber, of the shell body; the plurality of heat exchange tubes are horizontally arranged in the heat exchange chamber, and the two ends of the heat exchange tubes penetrate through the upper surfaces and the lower surfaces of the two partition plates correspondingly and are fixedly connected with the partition plates; and non-linear fluid channels are defined in the heat exchange tubes. High-temperature gas is forced to change the flowing direction in the fluid channels through the non-linear fluid channels, so that the turbulent flowing of the high-temperature gas and boundary layer separating or damaging are promoted, and the heat exchange efficiency is improved; and the length of the fluid channels is increased on the premise that the total length of the heat exchange tubes is not changed through the non-linear fluid channels, the heat exchange efficiency of the high-temperature gas in the heat exchange tubes is further improved, the emission of nitrogen-oxygen compound is reduced, the contemporary environment-friendly theme is met, and the intercooler has wide application prospect and applicability.

Description

technical field [0001] The invention relates to the technical field of automobile mechanical accessories, and more specifically relates to a turbocharger intercooler. Background technique [0002] In the turbocharger, the intercooler is usually used to reduce the intake air temperature of the engine. In order to improve the ventilation efficiency of the turbocharged engine, it is generally used as a turbocharged accessory. When the air enters the turbocharged, Its temperature will rise sharply, and its density will decrease accordingly. The intercooler is just to cool the air. The high-temperature air is cooled by the intercooler and then enters the engine. If the high-temperature air directly enters the engine, the engine will knock or even stall due to the high air temperature; [0003] The existing intercooler has the following defects: [0004] ①Limited by the size of the intercooler, the length of the heat dissipation pipe is insufficient, resulting in insufficient he...

AI Technical Summary

Problems solved by technology

[0004] ①Limited by the size of the intercooler, the length of the heat dissipation pipe is insufficient, resulting in insufficient heat dissipation efficiency of the high temperature gas in the heat exchange pipe;

[0005] ② There is a turning flow of the heat exchange medium in the heat exchange chamber, which will induce vibration to the heat exchange tubes; there will also be interference between multiple heat exchange tubes
