Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a current collector and splitter. Background Art

[0002] In the pipelines of the air-conditioning system, it is generally necessary to use multiple pipes for diversion or collection. For example, at the inlet of the heat exchanger, it is necessary to install multiple branch pipes on the diverter so that the refrigerant can enter the heat exchanger through the branch pipes. At the outlet of the heat exchanger, it is also necessary to install multiple branch pipes on the collector so that the refrigerant can be collected from the multiple branch pipes to the main pipe.

[0003] However, most of the current diverters only serve to divert the refrigerant on the main pipe to multiple branch pipes, and cannot ensure that the refrigerant can be evenly distributed to each branch pipe, which leads to unsatisfactory refrigerant distribution effect and easily affects the subsequent use of the refrigerant.

[0004] Furthermore, since it is necessary to weld the main pipe and multiple branch pipes on the diverter and the collector, and the existing diverters and collectors are generally made of copper, in order to save costs, the sizes of the diverters and collectors are generally small, which in turn leads to a small spacing between the welded pipes on the diverter and the collector, making the pipe welding relatively difficult and prone to problems such as refrigerant leakage due to poor welding. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a current collector and splitter.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A current collector and splitter comprises a shell and a bottom cover installed and closed on a port of the shell, wherein the shell is provided with a through hole 1, the bottom cover is provided with a cone corresponding to the through hole 1, the cone extends toward one side of the through hole, the bottom cover is provided with a plurality of through holes 2 evenly distributed on the outer periphery of the cone, the shell and the bottom cover form an inner cavity, the inner cavity is provided with an arc inner wall corresponding to the outer wall of the cone, and a cavity is provided inside the cone.

[0008] Preferably, a main pipe is welded and fixed on the first through hole, and a branch pipe is correspondingly welded and fixed on the second through hole.

[0009] Preferably, a gasket is provided in the shell, and a through hole three is opened on the gasket, which corresponds one-to-one with the through hole two. The gasket and the through hole two form an abutment platform for the branch pipe to abut and install.

[0010] Preferably, the size of through hole three is smaller than that of through hole two.

[0011] Preferably, a mounting hole is provided on the gasket, and the cone is fixed in the mounting hole.

[0012] Preferably, a convex ring is extended on the shell, the gasket is arranged in the convex ring, and the bottom cover is welded to the convex ring.

[0013] Preferably, the shell, bottom cover and cone are made of stainless steel.

[0014] Preferably, the gasket, main pipe and branch pipe are made of stainless steel.

[0015] Preferably, a main pipe joint made of copper is provided on one end of the main pipe away from the first through hole, and a branch pipe joint made of copper is provided on one end of the branch pipe away from the second through hole.

[0016] The beneficial effects of the present invention are:

[0017] 1. A cone is provided in the shell to guide the flow of the refrigerant. When diversion is required, the cone guides the diversion of the refrigerant entering the shell from the through hole 1, so that the refrigerant can be more evenly dispersed to the surroundings, diverted to multiple through holes 2 and output outwardly, and the cone cooperates with the arc-shaped inner wall of the shell to guide the diversion of the refrigerant to avoid the recoil of the refrigerant input into the shell, so as to ensure that the refrigerant can be diverted and transported more stably and efficiently; when collection is required, the refrigerant is transported into the shell from multiple through holes 2, so that the refrigerant can be collected in the shell and output outwardly through the through hole 1, and the arc-shaped inner wall of the shell cooperates with the outer periphery of the cone to guide the collected refrigerant, so that the converged refrigerant can flow into the through hole 1 more smoothly and stably, so as to avoid the flow velocity turbulence caused by the convergence of multiple refrigerants, so as to ensure the reliability and efficiency of the refrigerant collection;

[0018] 2. By installing a gasket on the bottom cover, the gasket and the bottom cover are provided with through holes three and two corresponding to each other inside and outside. The branch pipe is inserted into the abutment platform through the through hole two, and the branch pipe is installed and positioned to facilitate subsequent welding and fixing of the branch pipe, thereby reducing the welding difficulty of the branch pipe, reducing problems such as pipeline leakage caused by welding quality problems, and ensuring the quality of production and processing.

[0026] like Figure 1 to Figure 4 As shown, a collector and diverter includes a shell 1 and a bottom cover 2 installed and closed at a port of the shell 1, wherein the bottom cover 2 is welded and fixed to the shell 1, and the shell 1 and the bottom cover 2 form an inner cavity 11, wherein the inner cavity 11 is used to provide a space for diverting or collecting the input refrigerant.

[0027] The shell 1 is provided with a through hole 13 , which is located at the upper end of the shell 1 and is connected to the inner cavity 11 . The main pipe 5 is welded and fixed to the through hole 13 .

[0029] The bottom cover 2 is provided with a plurality of second through holes 21 evenly distributed on the outer circumference of the cone 4 , and branch pipes 6 are correspondingly welded and fixed to the second through holes 21 . The number of the branch pipes 6 is plural and they are installed one-to-one correspondingly to the second through holes 21 .

[0030] When flow diversion is required, the refrigerant is transported to the inner cavity 11 of the shell 1 through the main pipe 5 and diverted to a plurality of branch pipes 6 to be output to the outside.

[0031] Specifically, the cone 4 guides the refrigerant entering the shell 1 from the through hole 13 so that the refrigerant can be more evenly dispersed around and diverted to multiple through holes 21 and branch pipes 6 and output outward. The cone 4 cooperates with the arc-shaped inner wall 12 of the shell 1 to guide the diversion of the refrigerant to avoid the recoil of the refrigerant input into the shell 1, thereby ensuring that the refrigerant can be diverted and transported more stably and efficiently.

[0032] When flow collection is required, the refrigerant is transported to the inner cavity 11 of the shell 1 through a plurality of branch pipes 6 and collected to the main pipe 5 for external output.

[0033] Specifically, refrigerant is transported into the shell 1 through multiple through holes 21 and branch pipes 6, so that the refrigerant can be collected in the shell 1 and output outward through through hole 13 and main pipe 5, and the arc inner wall 12 of the shell 1 cooperates with the outer periphery of the cone 4 to guide the collected refrigerant, so that the converged refrigerant can flow into the through hole 13 and main pipe 5 more smoothly and stably, so as to avoid flow turbulence caused by multiple refrigerants converging together, thereby ensuring the reliability and efficiency of refrigerant collection.

[0034] In order to ensure the quality of welding of multiple branch pipes 6, a gasket 3 is provided in the shell 1, and a through hole three 31 corresponding to the through hole two 21 is opened on the gasket 3. The size of the through hole three 31 is smaller than that of the through hole two 21, and the through hole three 31 is connected to the inner cavity 11 through the through hole two 21 and the through hole three 31. The gasket 3 and the through hole two 21 form an abutment platform 32 for the branch pipe 6 to abut and install.

[0035] A plurality of branch pipes 6 are inserted and abutted onto the abutment platform 32 through corresponding through holes 21, and the branch pipes 6 are installed and positioned to facilitate subsequent welding and fixing of the branch pipes 6, thereby reducing the welding difficulty of the branch pipes 6, reducing problems such as pipeline leakage caused by welding quality problems, and ensuring the production and processing quality of this embodiment.

[0036] In order to ensure the reliability of the installation of the cone 4, the gasket 3 is welded and fixed on the bottom cover 2. A mounting hole 33 is opened on the gasket 3. The cone 4 is fixed in the mounting hole 33 and welded to the gasket 3. The gasket 3 and the cone 4 can also be an integrated structure, and the mounting hole 33 is provided to position the installation of the cone 4, ensuring that the cone 4 can be positioned up and down with the through hole 13.

By adopting stainless steel, the overall material cost of this embodiment is greatly reduced, and a cavity 41 is opened inside the cone 4. The cavity 41 is further provided to reduce the amount of material used and reduce the production cost.

[0039] A main pipe joint 51 made of copper is disposed on one end of the main pipe 5 away from the first through hole 13 , and a branch pipe joint 61 made of copper is disposed on one end of the branch pipe 6 away from the second through hole 21 .
