Description

Technical Field

[0001] This utility model relates to the field of automotive condenser technology, specifically a lightweight parallel flow automotive condenser. Background Technology

[0002] In automotive air conditioning systems, the condenser, as a core heat dissipation component, directly affects the air conditioning's cooling effect. Heat dissipation fins, as an important part of the condenser, improve heat exchange efficiency by increasing the heat dissipation area. However, existing automotive condenser heat dissipation fins have significant drawbacks in practical applications.

[0003] Existing technology includes a multifunctional parallel-flow automotive condenser disclosed in patent application number CN201821606234.0. In this condenser, the first manifold, oil pipe, fins, harmonica pipe, support plate, and second manifold are assembled and argon-arc welded together to form the condenser core assembly. The right bracket, first inlet / outlet connector, second inlet / outlet connector, oil inlet pipe, oil outlet pipe, and left bracket are brazed to the condenser core assembly to form the condenser. This multifunctional parallel-flow automotive condenser effectively solves the problem of leakage at the internal seals. The entire structure is compact and simple, easy to assemble, and the overall parallel-flow tube-belt automotive condenser mechanism has good strength, long service life, and good heat exchange function. However, in this technical solution, the heat dissipation fins are often fixed to the internal piping of the condenser in a complex manner, making disassembly extremely difficult when the equipment malfunctions and needs maintenance, or when the fins need cleaning or replacement due to dust accumulation or damage. The complex fixed structure not only increases the difficulty and time cost of maintenance personnel, but also makes it easy for improper external force to deform the fins or even damage the internal pipes during disassembly, further affecting the performance of the condenser; moreover, the complex connection method also leads to low production and assembly efficiency, making it difficult to meet the needs of large-scale automobile production.

[0004] In light of this, we propose a lightweight parallel-flow automotive condenser. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a lightweight parallel flow automotive condenser.

[0006] The technical solution of this utility model is:

[0007] A lightweight parallel-flow automotive condenser includes two parallel side pipes, with several parallel flat water pipes between them. Each flat water pipe connects to the interior of one of the two side pipes at both ends. Inlet and outlet pipes are installed on each of the two side pipes. A heat dissipation fin is positioned between each of the two flat water pipes. A side plate is mounted on the top of each side pipe, and the two ends of the heat dissipation fin are fixedly connected to the two side plates. By connecting the parallel side pipes to the flat water pipes, a parallel-flow structure is formed, allowing the coolant to be evenly distributed within the condenser, improving heat dissipation efficiency. The heat dissipation fins increase the heat dissipation area, enhancing heat exchange. Fixing the side plates to both ends of the heat dissipation fins facilitates the overall installation and removal of multiple heat dissipation fins.

[0008] As a preferred technical solution, a fixing block is welded to both ends of each side pipe, and both ends of the side plate are fixedly connected to the fixing blocks by two symmetrically arranged fixing bolts. This connection method has a simple structure and is convenient for installation and disassembly.

[0009] As a preferred technical solution, the heat dissipation fins are wavy, with the ends at the crests and troughs tightly fitted to the outer wall of the flat water pipe. Compared to straight fins, the wavy fin design increases the contact area and turbulence between the air and the fins, effectively improving the heat dissipation capacity on the air side. The tight fit between the fins and the flat water pipe at the crests and troughs allows for rapid dissipation of heat transferred by the flat water pipe, enhancing heat conduction efficiency.

[0010] As a preferred technical solution, a number of parallel support rods are fixedly installed between the two side plates, with each support rod horizontally passing through a number of heat dissipation fins. This provides additional support for the heat dissipation fins, enhances the stability of the overall condenser structure, and prevents the heat dissipation fins from deforming or being damaged due to vibrations or other factors during vehicle operation. Simultaneously, the support rods ensure a more orderly installation of the heat dissipation fins.

[0011] As a preferred technical solution, the inner ring wall of the flat water pipe is integrally formed with several evenly distributed protrusions, and the distance between adjacent protrusions is greater than the thickness of the protrusions. The protrusion design of the inner ring wall of the flat water pipe increases the contact area between the coolant and the pipe wall, promotes the turbulence of the coolant, enhances the heat exchange effect between the coolant and the pipe wall, and improves the heat dissipation performance.

[0012] As a preferred technical solution, the protruding teeth are arranged along the length direction of the flat water supply pipe, and the length of the protruding teeth is equal to the length of the flat water supply pipe. The arrangement of the protruding teeth along the length direction of the flat water supply pipe and being equal to the pipe length ensures that the coolant can fully contact the protruding teeth throughout the entire flow process, continuously enhancing the heat exchange effect and further improving heat dissipation efficiency.

[0013] As a preferred technical solution, the top of the heat dissipation fins is flush with the top of the side plate, and the bottom is flush with the bottom of the flat water pipe. This allows the heat dissipation fins to fit more closely with the flat water pipe in the width direction.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention establishes a parallel flow structure by connecting parallel side pipes to a flat water pipe, allowing the coolant to flow evenly within the condenser and improving heat dissipation efficiency. The addition of heat dissipation fins increases the heat dissipation area and enhances heat exchange. By fixing side plates at both ends of the heat dissipation fins, it is easy to install and disassemble multiple heat dissipation fins as a whole. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A lightweight parallel-flow automotive condenser includes two parallel side pipes 1, with several parallel flat water pipes 4 arranged between them. The two ends of each flat water pipe 4 are connected to the interior of the two side pipes 1. Each side pipe 1 has an inlet pipe 2 and an outlet pipe 3. A heat dissipation fin 5 is located between each of the two flat water pipes 4. A side plate 6 is installed on the top of each side pipe 1, and the two ends of the heat dissipation fin 5 are fixedly connected to the two side plates 6. By arranging the parallel side pipes 1 and the flat water pipes 4 to form a parallel-flow structure, the coolant can be evenly distributed within the condenser, improving heat dissipation efficiency. The heat dissipation fins 5 increase the heat dissipation area and enhance heat exchange. Fixing the side plates 6 to both ends of the heat dissipation fins 5 facilitates the overall installation and removal of multiple heat dissipation fins 5.

[0025] As a preferred embodiment, each side pipe 1 has a fixing block 10 welded to both ends, and both ends of the side plate 6 are fixedly connected to the fixing block 10 by two symmetrically arranged fixing bolts 60. This connection method has a simple structure and is convenient for installation and disassembly.

[0026] In this preferred embodiment, the heat dissipation fins 5 are wavy, and the ends located at the crests and troughs are tightly fitted to the outer wall of the flat water pipe 4. Compared with straight fins, the wavy heat dissipation fin design increases the contact area and turbulence between the air and the fins, effectively improving the heat dissipation capacity on the air side; the tight fit between the fins and the flat water pipe 4 at the crests and troughs allows for rapid dissipation of the heat transferred by the flat water pipe 4, enhancing heat conduction efficiency.

[0027] In a preferred embodiment, a plurality of parallel support rods 7 are fixedly installed between the two side plates 6, and the support rods 7 pass horizontally through the plurality of heat dissipation fins 5. This provides additional support for the heat dissipation fins 5, enhances the stability of the overall condenser structure, and prevents the heat dissipation fins 5 from deforming or being damaged due to vibration or other factors during vehicle operation; at the same time, the arrangement of the support rods 7 makes the installation of the heat dissipation fins 5 more regular.

[0028] In a preferred embodiment, the inner ring wall of the flat water pipe 4 is integrally formed with a plurality of evenly distributed protrusions 40, and the distance between adjacent protrusions 40 is greater than the thickness of the protrusions 40. The protrusions 40 design of the inner ring wall of the flat water pipe 4 increases the contact area between the coolant and the pipe wall, enhances the heat exchange effect between the coolant and the pipe wall, and improves the heat dissipation performance.

[0029] In a preferred embodiment, the protruding teeth 40 are arranged along the length of the flat water pipe 4, and the length of the protruding teeth 40 is equal to the length of the flat water pipe 4. The arrangement of the protruding teeth 40 along the length of the flat water pipe 4 and being equal to the length of the pipe ensures that the coolant can fully contact the protruding teeth 40 throughout the entire flow process, continuously enhancing the heat exchange effect and further improving the heat dissipation efficiency.

[0030] In this preferred embodiment, the top of the heat dissipation fins 5 is flush with the top of the side plate 6, and the bottom is flush with the bottom of the flat water pipe 4. This allows the heat dissipation fins 5 to fit more closely to the flat water pipe 4 in the width direction.

[0031] In use, the lightweight parallel flow automotive condenser of this invention allows coolant to flow in from the inlet pipe 2 of the side pipe 1. Because the two side pipes 1 are connected to several flat water delivery pipes 4 to form a parallel flow structure, the coolant is evenly distributed in each of the flat water delivery pipes 4. The coolant entering the flat water delivery pipes 4 benefits from the integrally formed and longitudinally distributed serrations 40 on the inner ring wall, increasing the contact area with the pipe wall and promoting turbulence, thus enhancing heat exchange with the pipe wall.

[0032] Heat is transferred from the flat water pipe 4 to the closely fitted corrugated heat dissipation fins 5. The corrugated design increases the contact area between the heat dissipation fins 5 and the air, and enhances air turbulence, thereby improving the heat dissipation capacity on the air side. Side plates 6 are fixedly connected to both ends of the heat dissipation fins 5, and support rods 7 between the side plates 6 provide fixation and support, ensuring the stability of the heat dissipation fins 5 and allowing heat to be dissipated more efficiently into the surrounding air. After heat exchange, the coolant finally flows out from the outlet pipe 3 of the side pipe 1, completing one heat dissipation cycle.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
