[0013] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0014] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0015] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0016] Reference Figure 1 to Figure 2A three-way pipe for refrigeration equipment, comprising a first leg pipe 1, a second leg pipe 2 and a third leg pipe 3 connected at the upper end, the lower end of the first leg pipe 1 is provided with a first bending portion 4 bent toward one side of the second leg pipe 2, the lower end of the first bending portion 4 is provided with a vertical first straight pipe 5, the axis of the first straight pipe 5 is located directly below the connection point of the first leg pipe 1, the second leg pipe 2 and the third leg pipe 3; the second leg pipe 2 is provided with a parallel second bending portion 6 corresponding to the first bending portion 4, and the lower end of the second bending portion 6 is provided with a vertical second straight pipe 7; The third leg tube 3 is provided with a third bending portion 8, and the lower end of the third bending portion 8 is provided with a vertical third straight tube 9. The distance B between the axis center line of the third straight tube 9 and the axis center line of the first straight tube 5 is the same as the distance C between the axis center line of the second straight tube 7 and the axis center line of the first straight tube 5. The three-way pipe is improved from the traditional flat M-type to a three-dimensional structure, thereby reducing the width of the three-way pipe, which is more suitable for the requirements of product miniaturization. At the same time, a structure with multiple bends is adopted, and the internal space is more complex, which can disperse the airflow energy, reduce vibration conduction, and reduce the noise generated by the product operation.

[0017] The front end of the third leg tube 3 is an "L"-shaped structure (i.e., an end close to the connection point between the first leg tube 1, the second leg tube 2 and the third leg tube 3), and the first bending portion 4 and the second bending portion 6 are inclined and bent toward the direction of the third leg tube 3 (such as Figure 2 As shown), while the three-way pipe forms a three-dimensional structure, the first straight pipe 5 is bent just below the connection point between the first leg 1, the second leg 2 and the third leg 3, and the third bent portion 8 extends from one end close to the "L"-shaped structure to the third straight pipe 9, presenting an inclined upward structure, thereby increasing the distance between the axis center line of the third straight pipe 9 and the axis center line of the first straight pipe 5, making this distance the same as the distance between the axis center line of the second straight pipe 7 and the axis center line of the first straight pipe 5. In the three-way hole, the distance between the two inlet pipes and the outlet pipe is consistent (the three-way pipe includes the first leg 1 responsible for introducing or discharging the refrigeration or heating medium into or out of the system, the second leg 2 and the third leg 3 used as the return air pipe and the heating liquid supply pipe), which can make the refrigerant in the three-way pipe more fully mixed, thereby improving the heat transfer efficiency.

[0018] The included angle between the first bending portion 4 and the second bending portion 6 and the vertical line is 38°-42°.

[0019] An angle A between a line connecting the axis center line of the third straight tube 9 and the axis center line of the first straight tube 5 and a line connecting the axis center line of the second straight tube 7 and the axis center line of the first straight tube 5 is 120°.

[0020] A vertical connection portion 10 is provided at the connection point between the first leg tube 1 and the second leg tube 2, and a sleeve portion 11 is provided on the third leg tube 3 corresponding to the connection portion 10. The sleeve portion 11 is sealed and sleeved on the connection portion 10, such as by welding.

[0021] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
