Intercooler

Abstract

The invention discloses an intercooler. The intercooler comprises a first tube plate, a second tube plate, a heat exchange tube, fins and side plates. The second tube plate and the first tube plate are arranged in parallel at intervals; the heat exchange tube is arranged between the first tube plate and the second tube plate and used for forming a first cooling channel; the fins are arranged on the heat exchange tube in a sleeving mode; a pressurized air channel is formed between the fins and the heat exchange tube; the side plates are arranged on the two sides of the intercooler and connectedwith the first tube plate and the second tube plate; and second cooling channels are formed in the side plates. According to the intercooler, the side plates can be cooled, the temperature change amplitude of the side plates is effectively reduced, then alternating stress generated by the temperature change of the side plates is reduced, fatigue damage of the side plates is relieved, the sealingeffect of the intercooler can be improved, the service life of the intercooler is prolonged, the adaptability of the intercooler to the variable working conditions of a diesel engine is improved, andthe working reliability and safety of a whole pressurization system are improved.

Description

technical field [0001] The invention relates to the field of heat exchanger manufacture, in particular to an intercooler. Background technique [0002] Relevant studies have shown that under the same air-fuel ratio conditions for diesel engines, the density of the supercharged air will increase by about 3% for every 10°C drop in the temperature of the supercharged air, and the output power of the diesel engine can be increased when other conditions remain unchanged. 3% to 5%. The efficiency of the diesel engine also increases as the temperature of the charge air intake decreases, and at the same time reduces pollutant emissions. Therefore, diesel engines usually use intercooling technology to cool the charge air. [0003] Currently commonly used intercoolers, due to structural reasons, are prone to deformation due to alternating stress when cooling the supercharged air, which will not only affect the sealing effect of the intercooler on the cooling medium, but also easily ...

Problems solved by technology

[0003] Currently commonly used intercoolers, due to structural reasons, are prone to deformation due to alternating stress when cooling the supercharged air, which will not only affect the sealing effect of the intercooler on the cooling medium, but also easily lead to leakage of supercharged air. It is conducive to improving the adaptability of the intercooler to the variable working conditions of the diesel engine, as well as the reliability and safety of the entire supercharging system
