Description

Technical Field

[0001] This invention relates to the field of radiator technology, and more particularly to high-efficiency radiators. Background Technology

[0002] As the quality of modern life continues to improve, cars have become increasingly common and highly regarded as a means of transportation. During the operation of a car, a large amount of heat is generated in the engine compartment due to the operation of the engine. If this heat is not cooled in time, it will directly affect the operation of other parts in the car. Therefore, in order to avoid this phenomenon, car manufacturers install a radiator in the engine compartment to dissipate heat and prevent the engine from overheating.

[0003] For example, patent application number CN202222954446.0 discloses an automotive radiator, including a main frame. Multiple evenly distributed condenser pipes are fixedly connected to the middle of the main frame. Fixing plates are fixedly connected to the upper and lower sides of the middle of the main frame. Connecting rods are fixedly connected to the left and right sides of the middle of the fan frame. A motor is fixedly connected to one end of two connecting rods facing each other. A rotating shaft is fixedly connected to the drive end of the motor. Multiple evenly distributed fan blades are fixedly connected to the outer periphery of the middle of the rotating shaft. This type of radiator dissipates heat from the condenser pipes through the fan, keeping the coolant inside the condenser pipes within a safe temperature range. However, since the fans are often fixed to the back of the frame using simple brackets, some radiators are equipped with multiple fans to improve airflow coverage. The simple brackets are difficult to guide airflow, resulting in low exhaust efficiency. Furthermore, replacing the entire row of fans requires disassembling each bracket individually, making replacement and maintenance cumbersome. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a high-efficiency heat sink to overcome the shortcomings of existing heat sinks.

[0005] To achieve the purpose of this invention, the invention is achieved through the following technical solution: a high-efficiency heat sink, including a housing, heat dissipation fins on the front and rear sides of the housing, and an inlet and outlet connector on the outer side of the housing. The inlet and outlet connectors are connected to a serpentine coil located inside the heat dissipation fins through a branch pipe structure.

[0006] The back of the shell is provided with a conical wind hood, and the side of the conical wind hood away from the shell is provided with a back plate. Multiple exhaust fans are installed on the back plate. A positioning window is opened on the back plate directly opposite the exhaust fans, and a round window is opened on the positioning plate directly opposite the positioning window.

[0007] The corners of the conical fan shroud are detachably connected to the housing via the first fastener, the corners of the back panel are detachably connected to the conical fan shroud via the second fastener, and the corners of the exhaust fan are detachably connected to the back panel via the third fastener.

[0008] A further improvement is that the branch pipe structure includes a first guide pipe and a second guide pipe, which are fixedly installed inside the shell. The inlet and outlet connectors are respectively connected to the first and second guide pipes. Multiple branch pipes are provided on the first and second guide pipes. The branch pipes on the first guide pipe are connected to the water inlet end of the serpentine coil, and the branch pipes on the second guide pipe are connected to the water outlet end of the serpentine coil.

[0009] A further improvement is that: multiple positioning plates are provided on the inner side of the housing, and the positioning plates are sleeved on the outer side of the serpentine coil and fixedly connected to the housing.

[0010] A further improvement is that the first bolt includes multiple bolt ears located on the outside of the conical wind shield. The bolt ears are fixedly located at the corners of the conical wind shield, and a first fixing bolt is fitted on the bolt ear. The first fixing bolt is threadedly connected to a bolt hole on the back of the housing.

[0011] A further improvement is that the second bolt includes a threaded hole at the corner of the back plate, a second fixing bolt is fitted in the threaded hole, the second fixing bolt passes through the back plate and is threadedly connected to a bolt hole on the outside of the conical wind shield.

[0012] A further improvement is that the third bolt includes a second fixing bolt fitted at the corner of the exhaust fan, the second fixing bolt passing through the exhaust fan and threadedly connected to a bolt hole opened on the back plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The branch pipe structure enables uniform liquid distribution, allowing the fins to effectively carry away heat and conduct heat effectively. The conical shroud with multiple exhaust fans is installed on the back of the housing. The split structure design allows for the removal and replacement of the entire row of exhaust fans at the same time, or for individual exhaust fans to be removed, improving maintenance efficiency.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a high-efficiency heat sink, including a housing 1. Heat dissipation fins 2 are provided on the front and rear sides of the housing 1. An inlet connector 3 and an outlet connector 4 are provided on the outer side of the housing 1. The inlet connector 3 and the outlet connector 4 are connected to a serpentine coil 7 located inside the heat dissipation fins 2 through a branch pipe structure.

[0023] The high-temperature liquid to be cooled enters through the inlet connector 3 and is distributed to each serpentine coil 7 via the branch pipe structure. As the high-temperature liquid flows within the serpentine coil 7, it transfers heat to the outer heat dissipation fins 2. The heat is then diffused into the air through the heat dissipation fins 2, completing the initial heat dissipation. The cooled liquid then collects in the branch pipe structure through the serpentine coil 7 and is finally discharged through the outlet connector 4, forming a heat dissipation cycle. The branch pipe structure achieves uniform liquid distribution. After the water flow is dispersed, the water resistance increases, the flow rate slows down, and the contact time with the heat dissipation fins increases, allowing the fins to effectively carry away heat and achieve effective heat conduction.

[0024] The back of the housing 1 is provided with a conical wind hood 9. The side of the conical wind hood 9 away from the housing 1 is provided with a back plate 12. Multiple exhaust fans 14 are installed on the back plate 12. A positioning window 17 is opened on the back plate 12 facing the exhaust fans 14. A round window 16 is opened on the positioning plate 8 facing the positioning window 17.

[0025] The corners of the conical fan shroud 9 are detachably connected to the housing 1 via the first fastener, the corners of the back plate 12 are detachably connected to the conical fan shroud 9 via the second fastener, and the corners of the exhaust fan 14 are detachably connected to the back plate 12 via the third fastener.

[0026] After the exhaust fan 14 is started, negative pressure is generated through the positioning window 17 of the back plate 12 and the round window 16 of the positioning plate 8, which guides the outside cold air through the gap between the heat dissipation fins 2 and the serpentine coil 7, and takes away the heat on the heat dissipation fins 2. The hot air is gathered by the conical fan shroud 9 and then discharged by the exhaust fan 14. Each component is detachably connected by the first, second and third bolts, and can be disassembled and maintained as needed.

[0027] The conical shroud 9 can gather airflow, prevent cold air from dissipating, and enhance the forced cooling effect. Together with the exhaust fan 14, it further accelerates heat dissipation and significantly improves the heat dissipation efficiency of the radiator. The split structure design allows for the removal and replacement of the entire row of exhaust fans 14 at the same time, or for the exhaust fans 14 to be removed individually, improving maintenance efficiency.

[0028] Regarding the branch pipe structure:

[0029] The branch pipe structure includes a first guide pipe 5 and a second guide pipe 6. The first guide pipe 5 and the second guide pipe 6 are fixedly installed inside the housing 1. The liquid inlet connector 3 and the liquid outlet connector 4 are respectively connected to the first guide pipe 5 and the second guide pipe 6. Multiple branch pipes are provided on the first guide pipe 5 and the second guide pipe 6. The branch pipe on the first guide pipe 5 is connected to the water inlet end of the serpentine coil 7, and the branch pipe on the second guide pipe 6 is connected to the water outlet end of the serpentine coil 7.

[0030] High-temperature liquid enters the first guide pipe 5 through the inlet connector 3, and is evenly distributed to each serpentine coil 7 through multiple branch pipes on the first guide pipe 5. After the liquid completes heat exchange and cooling in the serpentine coil 7, it flows into the corresponding branch pipe of the second guide pipe 6 through the outlet end of the serpentine coil 7, and finally converges into the second guide pipe 6, and is discharged through the outlet connector 4. The first and second guide pipes 56, together with the branch pipes, realize the even distribution and collection of liquid, ensuring that there is sufficient liquid flow in each serpentine coil 7, avoiding uneven heat dissipation caused by local coil idling. The branch pipe design disperses the water flow. After the water flow is dispersed, the water resistance increases, the flow rate slows down, and the contact time with the heat dissipation tube fins is prolonged. The fins can effectively carry away heat and carry out effective heat conduction.

[0031] Specifically, the inner side of the housing 1 is provided with multiple positioning plates 8, which are sleeved on the outside of the serpentine coil 7 and fixedly connected to the housing 1.

[0032] The positioning plate 8 limits and fixes the serpentine coil 7 by sleeve, preventing the serpentine coil 7 from shifting or deforming when liquid flows and impacts or equipment vibrates. At the same time, the positioning plate 8 can transfer some of the heat on the serpentine coil 7 to assist in heat dissipation.

[0033] Regarding the various fasteners:

[0034] The first fastener includes a plurality of bolt ears 10 located on the outside of the conical wind shield 9. The bolt ears 10 are fixedly located at the corners of the conical wind shield 9. A first fixing bolt 11 is mounted on the bolt ear 10. The first fixing bolt 11 is threadedly connected to a bolt hole opened on the back of the housing 1.

[0035] When installing the conical shroud 9, align the bolt lug 10 with the bolt hole on the back of the housing 1, screw the first fixing bolt 11 through the bolt lug 10 into the bolt hole and tighten it to fix the conical shroud 9 to the housing 1; when disassembling, loosen the first fixing bolt 11 in the opposite direction to separate the two.

[0036] The second fastener includes a threaded hole at the corner of the back plate 12, in which a second fixing bolt 13 is fitted. The second fixing bolt 13 passes through the back plate 12 and is threadedly connected to a bolt hole on the outside of the conical wind shield 9.

[0037] When installing the back plate 12, align the threaded holes at the corners of the back plate 12 with the bolt holes on the outside of the conical shroud 9, screw the second fixing bolt 13 through the threaded hole into the bolt hole of the conical shroud 9 and tighten it to complete the fixing of the back plate 12 and the conical shroud 9; when disassembling and maintaining, loosen the second fixing bolt 13 in the opposite direction to remove the back plate 12.

[0038] The third fastener includes a second fixing bolt 15 fitted at the corner of the exhaust fan 14. The second fixing bolt 15 passes through the exhaust fan 14 and is threadedly connected to a bolt hole opened on the back plate 12.

[0039] When installing the exhaust fan 14, align the corners of the exhaust fan 14 with the corresponding bolt holes on the back plate 12, and screw the second fixing bolt 15 through the exhaust fan 14 into the bolt hole on the back plate 12 and tighten it to fix the exhaust fan 14; when disassembling, loosen the second fixing bolt 15 in the opposite direction to remove the exhaust fan 14.
