[0016] The present application will be further described in detail below with reference to the drawings.

[0017] REFERENCE Figs. 1-4 The evaporation input pipe assembly with uniform liquid distribution comprises an input pipe 1, a distributor 2 and liquid distribution pipes 3, the liquid distribution pipes 3 are multiple, one end of the input pipe 1 is provided with a pipe joint 4, the distributor 2 is connected with the other end of the input pipe 1, the distributor 2 is provided with multiple distribution holes 21, the liquid distribution pipes 3 are connected with the distribution holes 21 one by one, the distributor 2 comprises a connecting portion 22 and a distribution portion 23, the connecting portion 22 is vertically arranged and in communication with the input pipe 1, the distribution portion 23 is conical, the end face of the distribution portion 23 is provided with a horizontal face 231 and an inclined face 232, the inclined face 232 is arranged at the outer periphery of the horizontal face 231, the outer end of the distribution hole 21 is located on the inclined face 232, and the distribution hole 21 is located on the distribution portion 23.

[0018] In actual use, the distribution pipes 3 are nine, the outer ends of each distribution pipe 3 are flush, which is convenient for connecting with the corresponding interfaces on the air conditioner evaporator, can adapt to high-power air conditioners, and meet the requirements of rapid refrigeration. Since the distribution part 23 is conical, the area of the end face of the distributor 2 can be increased, the opening of multiple distribution holes 21 can be met, and a certain thickness between adjacent distribution holes 21 is ensured, thereby meeting the corresponding strength requirements.

[0019] The inclined surface 232 is inclined downward by 20° relative to the horizontal surface 231, and the distribution holes 21 are uniformly distributed on the inclined surface 232. Therefore, the processing of the inclined surface 232 can be facilitated, and at the same time, the distribution holes 21 can be uniformly distributed on the end face of the distribution part 23, and the connection and cooperation of the distribution holes 21 and the distribution pipes 3 can be facilitated. At the same time, by providing the inclined surface 232, when the distribution pipes 3 are connected with the distribution holes 21, the distribution pipes 3 can be dispersed outward, avoiding mutual interference between the distribution pipes 3.

[0020] The connecting part 22 is sequentially provided with a first communication hole 221, a second communication hole 222 and a third communication hole 223, the first communication hole 221 is connected with the input pipe 1, the hole diameters of the first communication hole 221, the second communication hole 222 and the third communication hole 223 are gradually reduced, and each distribution hole 21 is in communication with the third communication hole 223. Among them, one end of the input pipe 1 is inserted into the first communication hole 221, which facilitates the connection of the input pipe 1 and the distributor 2. Since the hole diameters of the communication holes 221 in the connecting part 22 gradually decrease, the flow rate of the external refrigerant after flowing in can be increased, which facilitates the rapid flow of the refrigerant into each distribution hole 21, avoids the accumulation of the refrigerant, and facilitates the uniform distribution of the refrigerant by the distributor 2.

[0021] The evaporator input pipe assembly with uniform distribution further comprises a heat preservation pipe 5, which is sleeved outside the input pipe 1. Among them, the heat preservation pipe 5 is made of rubber plastic material, thereby playing a heat preservation and insulation role. When the input pipe 1 passes through other heating components during installation, the heat preservation pipe 5 can effectively prevent heat conduction into the input pipe 1, prevent the refrigerant from warming up, and facilitate the installation of the entire input pipe, thereby facilitating the installation of the entire input pipe.

[0022] Each distribution pipe 3 comprises a vertical part 31, a downward bending part 32 and a horizontal part 33, one end of the vertical part 31 is connected with the distribution hole 21, the top end of the downward bending part 32 is in communication with the other end of the vertical part 31, and the horizontal part 33 is connected with the bottom end of the downward bending part 32. Among them, each distribution pipe 3 is an integral molding structure, which is formed by bending processing of a copper pipe, thereby obtaining distribution pipes 3 with different bending degrees.

[0023] Therefore, in use, the refrigerant flows out from the distributor 2, enters the vertical part 31 of each distribution pipe 3, flows upward, then flows downward into the lower bend part 32, and finally flows out through the horizontal part 33. Since the lower bend part 32 is bent downward relative to the vertical part 31, when the refrigerant flows, buffering occurs at the communication between the two, so that the flow rate of the refrigerant can be slowed down, avoiding the refrigerant flowing out too fast and avoiding vibration with the air conditioner evaporator. Through each horizontal part 33, the distribution pipe 3 can be conveniently connected with each corresponding joint on the air conditioner evaporator.

[0024] One end of the heat preservation pipe 5 abuts against the pipe joint 4. Specifically, the outer diameter of the contact end of the pipe joint 4 is greater than the inner diameter of the heat preservation pipe 5, so that the heat preservation pipe 5 can be positioned by the pipe joint 4, and the heat preservation pipe 5 can be effectively prevented from falling off from the input pipe 1, thereby facilitating packaging and transportation of the input pipe.

[0025] The above is only the preferred embodiment of the present application, and it should be pointed out that for those skilled in the art, without departing from the inventive concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
