Detailed Description

The invention will be further described with reference to the following drawings and specific embodiments.

As shown in fig. 1 and fig. 2, the in-tube liquid flow type water-cooled intercooler of the present invention can be applied to a cooling system of charge air of a conventional energy vehicle, a hybrid vehicle, and a fuel cell vehicle, and the cooling water can be cooled by two-stage or multi-stage water temperature, but the function is not limited to cooling, and the cooling water can also be heated.

As shown in fig. 2, an in-tube liquid-flow water-cooled intercooler includes a first main fin 4, a second main fin 6, a first water chamber 3, a second water chamber 7, a first outer cover connecting plate 15, a second outer cover connecting plate 12, a first air inlet frame 16, and a second air outlet frame 11.

The connection structure of the first housing connection plate 15 and the first air inlet frame 16 is the same as the connection structure of the second housing connection plate 12 and the second air outlet frame 11, and the connection of the first housing connection plate 15 and the first air inlet frame 16 is used for representation and explanation: referring to fig. 2 and 4, the first outer joint plate 15 is welded after the one-peripheral contact surface 15-1 is in caulking contact with the one-peripheral contact surface 16-1 of the first air intake frame 16.

Connection between the first outer sheath connecting plate 15 and the second outer sheath connecting plate 12, as shown in fig. 2 and 5, the tongue-shaped interface connection between the contact surface 15-4 of the first outer sheath connecting plate 15 and the contact surface 12-1 of the second outer sheath connecting plate 12 is soldered, and the other side connection between the first outer sheath connecting plate 15 and the second outer sheath connecting plate 12 uses the same connection symmetrically.

The connection between the first and second sheath connecting plates 15 and 12 and the first and second main sheets 4 and 6 is the same, and as shown in fig. 2 and 3, the tongue-type connection between the contact surface 15-3 of the first sheath connecting plate 15 and the contact surface 4-2 of the first main sheet 4 is brazed.

The connection between first header 3 and first main strip 4 is the same as the connection between second main strip 6 and second header 7, and the connection between first header 3 and first main strip 4 is described as an example, as shown in fig. 2 and 3: the contact surface 3-1 of the first water chamber 3 and the contact surface 4-1 of the first main leaf 4 are connected by brazing.

The first casing web 15, the second casing web 12, the first main leaf 4 and the second main leaf 6 form a sealed channel on the charge air side. The first water chamber 3, the first main sheet 4, the second water chamber 7 and the second main sheet 6 are connected by brazing to form a sealed channel on the cooling water side; the first main sheet 4 and the first water chamber 3 form a closed cavity at the water inlet side, and the second main sheet 6 and the second water chamber 7 form a closed cavity at the water outlet side. The first outer sleeve connecting plate 15 and the first air inlet frame 16, and the second outer sleeve connecting plate 12 and the second air outlet frame 11 form the main factor of simplifying the welding seam of the pressurized air side channel of the first fluid channel; the connection of the first main strip 4 and the first water chamber 3 and the connection of the second main strip 6 and the second water chamber 7 form a weld seam simplification factor of the cooling water side channel of the second fluid channel.

The multi-stage water temperature control channel means that multi-stage water temperature cooling or heating can be realized by the structure of the invention in the cooling liquid channel of the second fluid channel, the heat dissipation capacity of each stage in the multi-stage channel is variable, and the heat dissipation capacity is adjusted by adjusting the width of the second heat dissipation pipe 13 and the first heat dissipation pipe 14 shown in fig. 2, and correspondingly adjusting the position of the first partition 5 and the second partition 10.

As shown in fig. 2, a first water cooling step in which a second channel coolant channel is formed by connecting water pipe 1, first water chamber 3, first partition 5, first main plate 4, first heat dissipating pipe 14, second main plate 6, second partition 10, second water chamber 7 and water pipe 8 in a closed manner; and the water pipe 2, the first water chamber 3, the first partition 5, the first main sheet 4, the second radiating pipe 13, the second main sheet 6, the second partition 10, the second water chamber 7 and the water pipe 9 are connected in a sealing manner to form a second channel cooling liquid channel.
