In-tube liquid-flow type water-cooling intercooler

Abstract

The invention relates to an in-tube liquid-flow type water-cooling intercooler which comprises a first main piece, a second main piece, a first water chamber, a second water chamber, a first outer sleeve connecting plate, a second outer sleeve connecting plate, a first gas inlet framework and a second gas outlet framework. Through braze-welding connection of the first main piece, the second main piece, the first water chamber, the second water chamber, the first outer sleeve connecting plate, the second outer sleeve connecting plate, the first gas inlet framework and the second gas outlet framework, a simple braze-welding connecting gap is realized, and a sandwich braze-welding connecting gap is avoided, so that gap continuity is strong, and process leakage detection and recognition is easy. The position of each partition plate and width of each heat dissipation tube can define control of two-stage or multi-stage water temperature grades in the same intercooler.

Description

technical field [0001] The invention relates to an automobile cooling system, in particular to an in-pipe liquid flow type water-cooled intercooler. Background technique [0002] In order to ensure the airtightness of the conventional liquid flow type water-cooled intercooler in the pipe, the structure between the external connecting plates is very complicated, there are too many brazing joints, too many sealing welding gaps, and there are double-layer interlayer welding gaps, the process is complicated and waste products The problem of high efficiency; and the liquid side water flow of the conventional liquid flow type water-cooled intercooler in the tube is a single-stage liquid flow, which cannot realize high and low temperature multi-stage heat dissipation on the same intercooler. For example, Chinese patent (CN106917667A) discloses an indirect intercooler, between the water chamber and the main board, between the water chamber and the baffle plate, and between the slots...

[0002] In order to ensure the airtightness of the conventional liquid flow type water-cooled intercooler in the pipe, the structure between the external connecting plates is very complicated, there are too many brazing joints, too many sealing welding gaps, and there are double-layer interlayer welding gaps, the process is complicated and waste products The problem of high efficiency; and the liquid side water flow of the conventional liquid flow type water-cooled intercooler in the tube is a single-stage liquid flow, which cannot realize high and low temperature multi-stage heat dissipation on the same intercooler

For example, Chinese patent (CN106917667A) discloses an indirect intercooler, between the water chamber and the main board, between the water chamber and the baffle plate, and between the slots on the bottom surface of the frame need to be brazed and sealed at the same time, and there is a double-layer interlayer welding gap , the brazing complexity is very high,
