Description

Technical Field

[0001] The utility model belongs to the technical field of condensers, and in particular relates to a corrosion-resistant anti-reflux condenser for an air conditioner of a new energy vehicle. Background Art

[0002] The air-conditioning system of new energy vehicles generally adopts an air-cooled condenser design. Its working principle is to use the forced flow of outside air through the heat sink of the condenser to effectively remove the heat in the high-temperature refrigerant vapor, cool it and turn it into liquid refrigerant. In this process, the heat released by the refrigerant vapor is absorbed by the surrounding air and discharged into the atmosphere. The cooling effect of the condenser is crucial to the refrigeration performance of the air-conditioning system. However, poor refrigeration effect is one of the common faults in the air-conditioning system of new energy vehicles, and poor heat dissipation of the condenser and internal gas-liquid reflux are the key factors leading to such problems.

[0003] In order to solve the above problems, condensers with anti-backflow design have appeared on the market. The Chinese utility model patent document with announcement number CN219693604U introduces an anti-backflow corrosion-resistant condenser for refrigerated trucks. The design prevents liquid backflow by combining a liquid storage tank and a one-way check valve. However, this design has exposed significant defects in practical applications. The condensed liquid needs to be discharged into the liquid storage tank for subsequent use. Therefore, the effect of adding an additional liquid storage tank in preventing backflow is not ideal. At the same time, it needs to be used in conjunction with a one-way check valve, which not only increases the complexity of the system, but also makes the overall cost and maintenance cost higher, which is not proportional to the achieved anti-backflow function. In addition, this design is difficult to adapt to changes in demand under different workloads.

[0004] Therefore, it is very necessary to invent a corrosion-resistant anti-reflux condenser for new energy vehicle air conditioning. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a corrosion-resistant anti-reflux condenser for a new energy vehicle air conditioner, comprising a condenser bracket, a modular anti-reflux condensation conduit, a steam inlet pipe port and a heat dissipation fin, wherein the modular anti-reflux condensation conduit and a plurality of the heat dissipation fins are fixedly mounted on the condenser bracket, the heat dissipation fins are connected to the modular anti-reflux condensation conduit, and the modular anti-reflux condensation conduit is connected to the steam inlet pipe port;

[0006] The modular anti-backflow condensation conduit includes a condensation conduit, a connecting elbow, disturbing rifling, a connection nozzle, a pipeline branch, and a flow guide plate. A plurality of condensation conduits are provided, and the disturbing rifling is provided on a part of the inner wall of the condensation conduit. The condensation conduits are inserted and fixed on the condenser bracket and a plurality of the heat dissipation fins. Two of the condensation conduits are connected through the connecting elbow, and two of the condensation conduits are respectively communicated with the steam inlet nozzle and the connection nozzle. Two connection nozzles are provided, and the other connection nozzle is communicated with a liquid storage tank. A plurality of pipeline branches are provided, which are communicated with each other and also with the connection nozzle. A flow guide plate is fixedly installed in each pipeline branch.

[0007] Preferably, the condenser bracket is a rectangular bracket made of four "U"-shaped plates. The condensation conduits inserted and fixed on the condenser bracket are of a "U" structure, and the disturbing rifling is not provided on the inner wall of the bending part of the condensation conduit.

[0008] Preferably, the disturbing rifling and the condensation conduit are integrally provided, and the disturbing rifling is a spiral convex structure. The condensation conduit is fixedly communicated with the connection nozzle through a flange.

[0009] Preferably, the connection nozzle, the pipeline branch, and the flow guide plate are of a modular one-way valve structure, and a plurality of the pipeline branches and the connection nozzle are fixedly connected and communicated through flanges.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] On the basis of the traditional condenser conduit design, the utility model has been ingeniously improved, significantly improving the condensation effect and system performance. By adding spiral disturbing rifling on the inner wall of the conduit, not only the inner wall surface area is effectively increased, strengthening the condensation efficiency and enabling the refrigerant vapor to condense into liquid more quickly. At the same time, this design also ingeniously changes the flow state of the refrigerant, causing beneficial disturbances of the liquid in the conduit, effectively reducing the accumulation and stagnation of the refrigerant in the pipeline, and thus significantly reducing the risk of backflow phenomenon.

[0012] In addition, this design also introduces a modular one-way valve structure, which makes the assembly and maintenance of the condenser simple and efficient. At the same time, the modular design also gives the condenser higher scalability, and users can flexibly add or remove modules according to actual needs to adapt to different workloads, providing a more flexible and efficient solution for the new energy vehicle air conditioning system.

[0020] As attached Figure 1 To Attachment Figure 3 As shown:

[0021] The corrosion-resistant and anti-backflow condenser for new energy vehicle air conditioners provided by the present utility model includes a condenser bracket 1, a modular anti-backflow condensation conduit 2, a steam inlet pipe orifice 3, and heat dissipation fins 4. The modular anti-backflow condensation conduit 2 and several heat dissipation fins 4 are fixedly installed on the condenser bracket 1. The heat dissipation fins 4 are connected to the modular anti-backflow condensation conduit 2, and the modular anti-backflow condensation conduit 2 is connected to the steam inlet pipe orifice 3.

[0022] The modular anti-backflow condensation conduit 2 includes a condensation conduit 21, a connecting elbow 22, disturbing rifling 23, a connecting pipe orifice 24, a pipeline branch 25, and a guide plate 26. A plurality of condensation conduits 21 are provided. The disturbing rifling 23 is provided on a part of the inner wall of the condensation conduit 21. The condensation conduits 21 are inserted and fixed on the condenser bracket 1 and several heat dissipation fins 4. Two condensation conduits 21 are connected through the connecting elbow 22. Two of the condensation conduits 21 are respectively connected to the steam inlet pipe orifice 3 and the connecting pipe orifice 24. Two connecting pipe orifices 24 are provided, and the other connecting pipe orifice 24 is connected to a liquid storage tank. A plurality of pipeline branches 25 are provided. While being interconnected, they are also connected to the connecting pipe orifice 24. A guide plate 26 is fixedly installed in each pipeline branch 25.

[0023] Embodiment 1:

[0024] Specifically, the condenser bracket 1 is a rectangular bracket made of four "U"-shaped plate bodies. This structure not only has high strength and good stability but also can fully meet the requirement of inserting and fixing the condensation conduit 21. The design of the rectangular bracket makes the overall structure of the condenser compact, facilitating installation and maintenance. The condensation conduit 21 inserted and fixed on the condenser bracket 1 is of a "U" shape. The disturbing rifling 23 is not provided on the inner wall of the bending part of the condensation conduit 21 because in the bending part, the flow state of the refrigerant has naturally changed, and there is no need to additionally set disturbing rifling to increase the disturbance and prevent the formation of unbeneficial disturbance. In addition, not setting the disturbing rifling 23 on the inner wall of the bending part can also reduce the processing difficulty and cost, and at the same time avoid unnecessary interference with the refrigerant flow.

[0025] Specifically, the disturbance rifling 23 and the condensation duct 21 are integrally arranged, ensuring a firm connection between the two, while also avoiding the problem of loosening or falling off due to long-term use. The disturbance rifling 23 adopts a spiral protrusion structure, which can effectively increase the surface area of ​​the inner wall of the condensation duct 21, thereby enhancing the contact area with the refrigerant vapor and improving the condensation efficiency. In addition, the spiral protrusion structure can also change the flow state of the refrigerant, causing it to form a certain disturbance. This disturbance helps to reduce the accumulation and stagnation of the refrigerant in the duct, thereby reducing the risk of reflux.

[0026] Specifically, the connecting pipe port 24, the pipeline branch 25 and the guide plate 26 are modular one-way valve structures, which adopt the Tesla valve structure principle. The connecting pipe port 24 and the connecting pipe branch 25 are fixedly connected by flanges. Considering the working environment of the condenser, the material of its internal components should have good corrosion resistance and thermal conductivity. For example, stainless steel or polymer materials can be used to manufacture the connecting pipe port 24, the pipeline branch 25 and the guide plate 26 to ensure their long-term stable operation.

[0027] Embodiment 2:

[0028] How it works

[0029] The utility model of corrosion-resistant anti-reflux condenser for new energy vehicle air conditioner realizes the high efficiency, corrosion resistance and anti-reflux functions of the condenser through modular design. Its working principle is mainly based on the following aspects:

[0030] Modular design: The one-way valve structure adopts a modular design, including a connecting pipe port 24, a pipe branch 25 and a guide plate 26. Modules (pipe branches 25) can be flexibly added or removed according to actual needs to adapt to different workloads, providing a more flexible and efficient solution for the air conditioning system of new energy vehicles.

[0031] Anti-backflow design: The connecting pipe port 24, the pipe branch 25 and the guide plate 26 in the modular anti-backflow condensation conduit 2 adopt a modular one-way valve structure based on the Tesla valve structure principle. This design can ensure the one-way flow of the refrigerant in the condenser and effectively prevent the occurrence of refrigerant backflow.

[0032] Disturbance design: Part of the inner wall of the condensation conduit 21 is provided with a disturbance rifling 23 with a spiral protrusion structure, which can effectively increase the surface area of ​​the inner wall of the condensation conduit and change the flow state of the refrigerant to form a beneficial disturbance. This disturbance helps to reduce the accumulation and stagnation of the refrigerant in the conduit and improve the condensation efficiency.

[0033] Workflow

[0034] Refrigerant entry: Refrigerant vapor enters the modular anti-reflux condensation conduit 2 through the vapor inlet pipe opening 3.

[0035] Condensation process: The refrigerant vapor flows in the condensation conduit 21 and is subjected to the action of the disturbance rifling 23 to form a beneficial disturbance, and exchanges heat with the heat dissipation fins 4, and is gradually condensed into liquid.

[0036] Refrigerant flow direction: The condensed refrigerant liquid flows to the connecting pipe ports 24 through the pipeline branch 25, and one of the connecting pipe ports 24 is connected to the liquid storage tank to store the refrigerant liquid.

[0037] Anti-backflow mechanism: The modular one-way valve structure ensures the one-way flow of refrigerant in the condenser. When the refrigerant liquid flows in the pipeline branch 25, the Tesla valve structure principle allows the refrigerant to flow only in a predetermined direction, preventing the occurrence of backflow.

[0038] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
