Description

Technical Field

[0001] This utility model relates to the field of condenser technology, specifically to the optimization of condenser piping structure. Background Technology

[0002] As a key heat exchange component of the automotive air conditioning system, the automotive condenser uses a complex heat exchange principle to convert the high-temperature, high-pressure gaseous refrigerant discharged from the compressor into a liquid state, thus completing the refrigeration cycle.

[0003] Improving the condenser outlet piping in automobiles is crucial because condenser products of the same model may come in two specifications: dense and standard (different density of heat sinks and flat tubes). However, the piping is not interchangeable during the design process, requiring different piping designs for different models. This necessitates the development of different molds for manufacturing different piping, increasing production costs and reducing production efficiency due to the need to switch between different molds during production. Therefore, an optimized condenser piping structure is urgently needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an optimized condenser piping structure to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The optimized condenser piping structure includes a liquid guide pipe one and a liquid guide pipe two. A liquid inlet assembly is provided on the outer wall of the liquid guide pipe one, and a pipe is inserted into the liquid inlet assembly. The pipe includes a liquid outlet opening, and a clearance groove is formed on the outer wall of the liquid outlet opening. The liquid outlet opening is located inside the liquid guide pipe one. A heat dissipation flat pipe is provided between the liquid guide pipe one and the liquid guide pipe two. Mounting assemblies are welded to the outer walls of both the liquid guide pipe one and the liquid guide pipe two. A liquid outlet connector is provided on the outer surface of the liquid guide pipe two, and the liquid guide pipe two is connected to the liquid outlet connector.

[0007] In a preferred embodiment of this utility model, the outer walls of both the first and second liquid guiding tubes are provided with a plurality of insertion holes, the heat dissipation flat tube is inserted into the insertion holes, and the first and second liquid guiding tubes are connected through the heat dissipation flat tube.

[0008] In a preferred embodiment of this utility model, the installation assembly includes a fixing frame welded to the outer walls of the first and second liquid guiding pipes, and a shock-absorbing rubber sleeve is fitted into the fixing hole on the fixing frame.

[0009] In a preferred embodiment of this utility model, the liquid inlet assembly includes a connecting member disposed on the outer wall of a liquid guiding pipe. The upper surface of the connecting member has a liquid inlet, and the side surface of the connecting member has a liquid outlet. The liquid inlet and the liquid outlet are connected.

[0010] In a preferred embodiment of this utility model, the liquid inlet of the pipeline is connected to the liquid outlet on the liquid inlet assembly, and the clearance groove is located on the periphery of one end of the heat dissipation flat tube.

[0011] In a preferred embodiment of this utility model, both the first and second liquid guiding pipes are equipped with baffles, and the coolant flows in an S-shape within the condenser under the action of the baffles.

[0012] In a preferred embodiment of this utility model, the clearance groove on the pipeline is a spherical groove with a size of 3mm*3mm.

[0013] In the above technical solution, the optimized condenser piping structure provided by this utility model has the following beneficial effects:

[0014] (1) By opening the clearance groove, the liquid outlet pipeline of the same model of condenser can be used for both high-density and ordinary condensers, which reduces the design and production of different pipelines for different specifications of products and improves the versatility and interchangeability of products.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, the optimized condenser piping structure provided in this embodiment of the present invention includes a liquid guiding pipe 1 and a liquid guiding pipe 2. A liquid inlet assembly 4 is provided on the outer wall of the liquid guiding pipe 1, and a pipe 6 is inserted into the liquid inlet assembly 4. The pipe 6 includes a liquid outlet opening 61. A clearance groove 62 is provided on the outer wall of the liquid outlet opening 61 of the pipe 6. The liquid outlet opening 61 is located inside the liquid guiding pipe 1. A heat dissipation flat pipe 7 is provided between the liquid guiding pipe 1 and the liquid guiding pipe 2. An installation assembly 3 is welded to the outer wall of both the liquid guiding pipe 1 and the liquid guiding pipe 2. A liquid outlet connector 5 is provided on the outer surface of the liquid guiding pipe 2, and the liquid guiding pipe 2 is connected to the liquid outlet connector 5.

[0025] In this embodiment, a pipe 6 is inserted into the liquid inlet assembly 4. The pipe 6 is made of brass and includes a liquid outlet 61. A clearance groove 62 is provided on the outer wall of the liquid outlet 61 of the pipe 6. In order to avoid interference during the assembly of the heat dissipation flat tube 7, the liquid outlet 61 is located inside the liquid guiding pipe 1. The liquid inlet of the pipe 6 is connected to the liquid outlet 43 on the liquid inlet assembly 4 to ensure the unobstructed passage of the internal passage of the condenser. The clearance groove 62 is located on the outer periphery of one end of the heat dissipation flat tube 7 to avoid interference between them.

[0026] Specifically, the clearance groove 62 on the pipe 6 is a spherical groove with a size of 3mm*3mm. It can be designed as an eccentric clearance groove 62 according to actual conditions. This allows the pipe 6 of the same type of condenser to be used for both high-density and ordinary condensers, reducing the design and production of different pipe 6 for different specifications of products, and improving the versatility and interchangeability of the products.

[0027] In this embodiment, a heat dissipation flat tube 7 is provided between the liquid guiding tube 1 and the liquid guiding tube 2. The flat tube 7 is made of high-purity aluminum. The outer walls of the liquid guiding tube 1 and the liquid guiding tube 2 are provided with several insertion holes 8. The heat dissipation flat tube 7 is inserted into the insertion holes 8 and forms an interference fit with the insertion holes 8 on the outer walls of the liquid guiding tube 1 and the liquid guiding tube 2. During assembly, silver solder paste is used for welding. The liquid guiding tube 1 and the liquid guiding tube 2 are connected through the heat dissipation flat tube 7. The outer surface of the liquid guiding tube 2 is provided with a liquid outlet connector 5, and the liquid guiding tube 2 is connected to the liquid outlet connector 5.

[0028] In this embodiment, mounting components 3 are welded to the outer walls of both the first liquid guide pipe 1 and the second liquid guide pipe 2. The mounting components 3 include a fixing frame 31 welded to the outer walls of the first liquid guide pipe 1 and the second liquid guide pipe 2. The fixing frame 31 is formed by bending Q235B steel plate. A shock-absorbing rubber sleeve 32 is sleeved in the fixing hole on the fixing frame 31. The shock-absorbing rubber sleeve 32 is made of neoprene rubber and has a steel wire skeleton embedded inside to enhance the support force, which can effectively absorb the vibration generated during the operation of the equipment.

[0029] In this embodiment, a liquid inlet assembly 4 is provided on the outer wall of the liquid guide tube 1. The liquid inlet assembly 4 includes a connecting member 41 provided on the outer wall of the liquid guide tube 1. The connecting member 41 is made of brass H62 material and is CNC machined. A liquid inlet 42 is provided on the upper surface of the connecting member 41. The liquid inlet 42 is equipped with a quick-connect fitting for easy and quick connection to an external pipe. A liquid outlet 43 is provided on the side surface of the connecting member 41. The liquid inlet 42 and the liquid outlet 43 are connected.

[0030] In this embodiment, both the liquid guiding pipe 1 and the liquid guiding pipe 2 are equipped with baffle plates 9. The baffle plates 9 are made of aluminum alloy and are fixed to the inner wall of the pipe by ultrasonic welding. Under the action of the baffle plates 9, the coolant flows in an S-shape in the condenser, which increases the path length and residence time of the coolant and effectively improves the heat dissipation effect of the coolant.

[0031] Working steps: 1. Fix the condenser to the equipment through the installation component 3. The coolant enters the liquid guide pipe 1 through the liquid inlet component 4 and the pipe 6. The baffle plate 9 installed inside the liquid guide pipe 1 and the liquid guide pipe 2 causes the coolant to flow in an S-shape in the condenser. The coolant flows from the liquid guide pipe 1 through the heat dissipation flat pipe 7 to the liquid guide pipe 2. When the coolant flows through the heat dissipation flat pipe 7, it exchanges heat with the outside and achieves the purpose of heat dissipation. After heat dissipation, the coolant is discharged from the liquid guide pipe 2 through the liquid outlet connector 5.

[0032] Second, the clearance groove 62 on the pipe 6 is located on the outer periphery of one end of the heat dissipation flat tube 7, and the clearance groove 62 is a spherical groove, which provides clearance space for the heat dissipation flat tube 7 component when the pipe 6 is installed, ensuring the adaptability and versatility of the pipe 6.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
