Description

Technical Field

[0001] This invention relates to the field of air conditioner distributor technology, specifically to a steel-embedded distributor and its manufacturing process. Background Technology

[0002] The air conditioning distributor is a crucial component in the air conditioning refrigeration piping system. Its function is to evenly distribute refrigerant to each branch pipe of the evaporator to achieve optimal cooling performance. Currently, existing air conditioning distributors are typically constructed entirely of copper. Copper has good thermal conductivity and processing properties, but its cost is relatively high, especially in non-critical pressure-bearing and non-critical heat exchange parts such as the flow guide cone, leading to a higher overall material cost. Furthermore, during the manufacturing of integral copper distributors, the flow guide cone often requires cold heading, but cold heading is prone to burrs and has issues with low machining precision. Summary of the Invention

[0003] The main objective of this invention is to provide a steel-embedded distributor and its manufacturing process to overcome the problems existing in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A steel-embedded distributor includes a distributor body, one end of which is provided with a liquid inlet and the other end with multiple liquid outlets. A flow guide cone is installed inside the distributor body. The distributor body is made of copper and the flow guide cone is made of stainless steel.

[0005] Furthermore, the distributor body includes an inlet section and a diversion section. The inlet section includes an inlet section, a necking section, a horizontal flow section and an expansion section connected sequentially from top to bottom. The lower end of the expansion section is connected to the diversion section.

[0006] Furthermore, the outer bottom wall of the guide cone is fixedly connected to the inner bottom wall of the diversion section, and the two outer walls of the guide cone are fixedly connected to the two inner walls of the diversion section.

[0007] Furthermore, the protruding portion of the guide cone is located at the center of the interface between the liquid inlet and the diversion section.

[0008] Furthermore, the liquid inlet is located at the top of the liquid inlet section, the liquid outlet is located at the bottom of the diversion section, the liquid inlet section has an inlet channel communicating with the liquid inlet, and the diversion section has an outlet channel communicating with the liquid outlet.

[0009] Furthermore, the main body of the guide cone is provided with a diversion channel, and a liquid distribution cavity is formed between the inner wall of the expansion section and the protruding part of the guide cone. The upper end of the liquid distribution cavity is connected to the liquid inlet channel, the lower end is connected to the diversion channel, and the lower end of the diversion channel is connected to the liquid outlet channel.

[0010] Furthermore, the axis of the liquid inlet is arranged parallel to the axis of the liquid outlet.

[0011] A manufacturing process for a steel-embedded distributor includes the following steps: S1: Material preparation: Select a copper strip and use a stretching process to obtain the main body blank of the distributor; S2: Preparation of the guide cone: Stainless steel powder is molded by powder injection molding to obtain a guide cone made of stainless steel. S3: The prepared guide cone is pressed into the interior of the distributor body using a stamping process to fix the two together; S4: Spinning, the distributor body blank is spun using a spinning machine to form the necking section, the horizontal flow section and the diameter expansion section.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The main body of the distributor of this invention is made of copper, and the guide cone is made of stainless steel, forming a "steel-embedded" structure. The guide cone uses stainless steel, which has a lower cost, instead of copper. While ensuring the overall performance of the distributor, the amount of copper used is effectively reduced, and the cost of raw materials is greatly reduced. The stainless steel guide cone is formed by powder injection molding. Compared with the cold heading process of traditional copper guide cones, powder injection molding can produce parts with more precise dimensions, effectively avoid the burr defects that are easily generated in the cold heading process, significantly improve the dimensional accuracy and surface quality of the guide cone, and thus improve the working stability and flow distribution uniformity of the distributor.

Detailed Implementation

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Example 1

[0019] Combination Figures 1 to 3 This embodiment provides a steel-embedded distributor, including a distributor body 1. One end of the distributor body 1 is provided with a liquid inlet 11, and the other end is provided with multiple liquid outlets 12. A flow guide cone 2 is installed inside the distributor body 1. The distributor body 1 is made of copper, and the flow guide cone 2 is made of stainless steel.

[0020] In this scheme, the main body 1 of the distributor is made of copper and the guide cone 2 is made of stainless steel, forming a "steel-embedded" structure. The guide cone 2 uses stainless steel, which has a lower cost, instead of copper. While ensuring the overall performance of the distributor, the amount of copper used is effectively reduced, and the cost of raw materials is significantly reduced.

[0021] like Figure 1 As shown, in this embodiment, the distributor body 1 includes an inlet section 3 and a diversion section 4. The inlet section 3 includes an inlet section 31, a necking section 32, a horizontal flow section 33 and an expansion section 34 connected sequentially from top to bottom. The lower end of the expansion section 34 is connected to the diversion section 4.

[0022] like Figure 2-3 As shown, in this embodiment, the inlet 11 is located at the top of the inlet section 3, and the outlet 12 is located at the bottom of the diversion section 4. The inlet section 3 has an inlet channel 5 communicating with the inlet 11, and the diversion section 4 has an outlet channel 6 communicating with the outlet 12. The main body of the guide cone 2 has a diversion channel 7. A liquid distribution cavity 8 is formed between the inner wall of the expansion section 34 and the protrusion of the guide cone 2. The upper end of the liquid distribution cavity 8 communicates with the inlet channel 5, the lower end communicates with the diversion channel 7, and the lower end of the diversion channel 7 communicates with the outlet channel 6.

[0023] This design, through the necking section 32, the horizontal flow section 33, and the diameter expansion section 34 of the liquid inlet, combined with the protruding position of the guide cone 2 and the setting of the diversion channel 7, allows the refrigerant to flow smoothly from the liquid inlet channel 5 through the liquid distribution chamber 8 and the diversion channel 7 to each liquid outlet channel 6. The flow transition is smooth and the flow resistance is small, which is conducive to the uniform distribution of refrigerant among each liquid outlet 12, thereby improving the cooling effect of the air conditioning system.

[0024] like Figure 3 As shown, in this embodiment, the outer bottom wall of the guide cone 2 is fixedly connected to the inner bottom wall of the diversion section 4, and the two outer walls of the guide cone 2 are fixedly connected to the two inner walls of the diversion section 4. The protruding part of the guide cone 2 is located at the center of the interface between the liquid inlet section 3 and the diversion section 4.

[0025] By using this scheme, the refrigerant coming out of the liquid inlet channel 5 is further guided by the flow guide cone 2, causing it to change direction, thereby further improving the atomization effect of the refrigerant and improving the uniformity of the flow distribution.

[0026] In this embodiment, the axis of the liquid inlet 11 is arranged parallel to the axis of the liquid outlet 12.

[0027] Example 2

[0028] This embodiment provides a manufacturing process for a steel-embedded distributor, including the following steps: S1: Blanking: Select a copper strip and use a stretching process to obtain the main body blank of the distributor; S2: Preparation of guide cone 2: Stainless steel powder is molded by powder injection molding process to obtain guide cone 2 made of stainless steel. S3: The prepared guide cone 2 is pressed into the interior of the distributor body 1 by stamping process to fix the two. S4: Spinning, the distributor body 1 blank is spun using a spinning machine to form a necking section 32, a horizontal flow section 33 and an expanding diameter section 34.

[0029] In this embodiment, the stainless steel guide cone is formed using powder injection molding. Compared to the traditional cold heading process for copper guide cones, powder injection molding can produce parts with complex shapes and precise dimensions, effectively avoiding burr defects that are easily generated in the cold heading process. This significantly improves the dimensional accuracy and surface quality of the guide cone, thereby enhancing the working stability and flow distribution uniformity of the distributor. The copper distributor body is formed using a stretching process, which is simple, efficient, and reduces processing difficulty and manufacturing costs.

[0030] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
