Preferably, the connecting pipe comprises a main pipe, the upper end of the main pipe is bent to form a first bent pipe, the lower end of the main pipe is bent to form a second bent pipe, and the upper end and the lower end of the main pipe are respectively bent to form the first bent pipe and the second bent pipe, so that the whole three-way pipe is convenient to install.

Preferably, the side of the connecting pipe is provided with a positioning protrusion, the positioning protrusion is arranged at the opening and communicated with the connecting pipe, one end of the third branch pipe is welded on the positioning protrusion, the positioning protrusion is arranged at the opening, the third branch pipe is welded on the positioning protrusion to realize the welding between the third branch pipe and the connecting pipe, and the welding is convenient.

Preferably, one end of the third branch pipe extends to the positioning protrusion, the outer circumference of the third branch pipe is welded with the end face of the positioning protrusion, the third branch pipe is positioned by the positioning protrusion, the third branch pipe is conveniently welded on the connecting pipe, and particularly the third branch pipe extends to the inside of the positioning protrusion.

Preferably, the depth of the third branch pipe extending into the positioning protrusion is less than or equal to the length of the positioning protrusion, so that the connection pipe is not affected, and the connection strength between the third branch pipe and the positioning protrusion is ensured.

Preferably, the depth of the third branch pipe extending into the positioning protrusion is equal to the length of the positioning protrusion, and the effect is good.

Preferably, the length of the positioning protrusion is 10mm to 20mm, preferably 10mm, 15mm and 20 mm.

A heat exchanger comprises the three-way pipe.

Drawings

FIG. 1 is a perspective view of a prior art tee.

Fig. 2 is a perspective view of the three-way pipe of the present invention.

Fig. 3 is a partial sectional view of the tee of the present invention.

The device comprises a first branch pipe, a second branch pipe, a third branch pipe, a pipe 2, a connecting pipe 3, an opening 4, a main pipe 5, a first bent pipe 6, a second bent pipe 7 and a positioning protrusion.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 2, the utility model provides a three-way pipe, including first branch pipe, second branch pipe and third branch pipe 1, first branch pipe and second branch pipe are a whole, and first branch pipe and second are a combination into a takeover 2, establish opening 3 in takeover 2 sides, to third branch pipe 1 welding on opening 3, realize third branch pipe 1 and takeover 2 be connected and realize the third branch pipe 1 simultaneously and takeover 2 between the intercommunication, reduced the welded number of times. .

As an example, the connecting pipe comprises a main pipe 4, the upper end of the main pipe 4 is bent to form a first bent pipe 5, so that the upper ends of the first bent pipe 5 and the main pipe 4 are first branch pipes; the lower end of the main pipe 4 is bent to form a second bent pipe 6, so that the lower ends of the second bent pipe 6 and the main pipe 4 are second branch pipes.

As an embodiment, as shown in fig. 2 and 3, a positioning protrusion 7 is set at the opening 3, the positioning protrusion 7 is hollow, that is, the positioning protrusion 7 is an annular protrusion, and the third branch pipe 1 is welded on the positioning protrusion 7 to connect the third branch pipe 1 with the main pipe 4, while ensuring that the third branch pipe 1 is communicated with the main pipe 4. In particular, the positioning projection 7 and

as an embodiment, one end of the third branch pipe 1 extends into the positioning bulge 7, so that the outer circumference of the third branch pipe 1 is welded with the end face of the positioning bulge 7.
