Description

Technical Field

[0001] This utility model relates to the field of automotive radiator technology, specifically to a multi-channel automotive radiator. Background Technology

[0002] The car radiator is a key component of the automotive cooling system, primarily used to dissipate the heat generated by the engine during operation, ensuring the engine operates within a suitable temperature range. The heat generated by the engine is transferred to the radiator's cooling pipes via coolant. The high-temperature coolant flows through the cooling pipes inside the radiator, transferring heat through the pipe walls to the cooling fins, and finally being dissipated into the air by the cooling fan. However, conventional radiators use circular cooling pipes. When the high-temperature coolant flows through these pipes, the liquid near the pipe walls can transfer heat more directly and quickly, while the liquid in the center of the pipes transfers heat more slowly. This limits the overall heat transfer efficiency of the coolant as it flows through the pipes, hindering heat dissipation. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model proposes a multi-channel automotive radiator to solve the above problems.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] This utility model provides a multi-channel automotive radiator, comprising:

[0006] The shell is open on both the front and back sides, and has an inlet chamber and an outlet chamber on each side.

[0007] The multi-channel structure includes connecting pipes, heat dissipation plates, and arc-shaped connecting pipes. Multiple heat dissipation plates are longitudinally spaced within the housing. Each heat dissipation plate has multiple conveying channels distributed at intervals. The two ends of the conveying channels extend laterally to the two ends of the heat dissipation plates. One end of each heat dissipation plate is connected to one end of its adjacent heat dissipation plate by an arc-shaped connecting pipe, and the end of the arc-shaped connecting pipe is connected to the end of the conveying channel on the corresponding heat dissipation plate. One end of two connecting pipes is connected to the inlet chamber and the outlet chamber, respectively. The other ends of the two connecting pipes are connected to the ends of the uppermost and lowermost heat dissipation plates, respectively, and are connected to the ends of the corresponding conveying channels.

[0008] Heat dissipation fins, multiple heat dissipation fins are spaced apart inside the housing and connected to the outside of the multi-channel structure.

[0009] Furthermore, the heat sink is inclined relative to the front of the housing.

[0010] Furthermore, the highest point of the heat sink is lower than the lowest point of the heat sink above it.

[0011] Furthermore, the heat sink has ventilation slots located between two adjacent conveying channels.

[0012] Furthermore, the connection ends of the connecting pipe and the arc-shaped butt joint pipe to the heat sink are flat and constricted.

[0013] Furthermore, a heat dissipation fin is provided inside the arc-shaped connecting pipe, and the heat dissipation fin bends synchronously with the path of the arc-shaped connecting pipe.

[0014] As can be seen from the above technical solution, this utility model provides a multi-channel automotive radiator:

[0015] The high-temperature coolant from the car engine enters the inlet chamber through pipes and then flows into a multi-channel structure. As the coolant flows from the connecting pipes and various arc-shaped connecting pipes through the radiator fins, it is divided and passes through various delivery channels on the radiator fins. This increases the contact area between the coolant and the radiator fins, while reducing the distance between the center of the coolant and the radiator fins, allowing heat in the coolant to be transferred away more quickly and improving heat dissipation. Furthermore, whenever the coolant flows from one delivery channel on a radiator fin back into the next arc-shaped connecting pipe or connecting pipe, it is remixed, resulting in a more uniform temperature distribution for subsequent heat dissipation.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] like Figure 1-4 As shown, this embodiment provides a multi-channel automotive radiator, including a housing 1, a multi-channel structure 2, and heat dissipation fins 3.

[0027] Both the front and rear sides of the housing 1 are open, and a cooling fan (not shown) is installed on the back of the housing 1. A water inlet chamber 11 and a water outlet chamber 12 are respectively provided on both sides of the housing 1. The water inlet chamber 11 and the water outlet chamber 12 are respectively connected to the water outlet pipe and the water inlet pipe at the engine.

[0028] The multi-channel structure 2 includes a connecting pipe 21, heat sink 22, and an arc-shaped connecting pipe 23. Multiple heat sinks 22 are longitudinally spaced within the housing 1. Each heat sink 22 has multiple conveying channels 221 spaced apart. The conveying channels 221 are narrow channels with a diameter smaller than the diameter of the arc-shaped connecting pipe 23 and the connecting pipe 21. Both ends of the conveying channels 221 extend laterally to both ends of the heat sink 22. One end of each heat sink 22 is connected to one end of its adjacent heat sink 22 by an arc-shaped connecting pipe 23, and the end of the arc-shaped connecting pipe 23 communicates with the end of the conveying channel 221 on the corresponding heat sink 22, thus ensuring that the conveying channels 221 on each heat sink 22 are sequentially connected. Figure 2 As shown, the entire multi-channel structure 2 extends in an S-shaped path. One end of the two connecting pipes 21 is connected to the water inlet chamber 11 and the water outlet chamber 12 respectively. The other end of the two connecting pipes 21 is connected to the ends of the uppermost and lowermost heat dissipation plates 22 respectively, and is connected to the ends of the corresponding conveying channels 221.

[0029] Multiple heat dissipation fins 3 are spaced apart inside the housing 1 and connected to the outside of the multi-channel structure 2.

[0030] When the radiator is working, the high-temperature coolant from the car engine enters the inlet chamber 11 through pipes, and then flows to the multi-channel structure 2. As the coolant flows from the connecting pipe 21 and each arc-shaped connecting pipe 23 through the heat dissipation fins 22, it forms a branch and passes through the various delivery channels 221 on the heat dissipation fins 22. This increases the contact area between the coolant and the heat dissipation fins 22, while reducing the distance between the center of the coolant and the heat dissipation fins 22, allowing the heat in the coolant to be transferred away more quickly and improving the heat dissipation effect. Furthermore, whenever the coolant flows from the delivery channel 221 on one heat dissipation fin 22 back into the next arc-shaped connecting pipe 23 or connecting pipe 21, it can be remixed, making the temperature distribution of the coolant more uniform, so that subsequent heat can be dissipated.

[0031] Preferably, the heat sink 22 is inclined on the front of the housing 1, and the heat sink 22 forms an angle with the front of the housing 1. When the car is in motion and the cooling fan is working, the surface of each conveying channel 221 on the heat sink 22 can meet the airflow and promote heat dissipation.

[0032] Furthermore, the highest point of the heat sink 22 is lower than the lowest point of the heat sink 22 above it, so that each heat sink 22 avoids each other and the front side of each conveying channel 221 is unobstructed, which further promotes heat dissipation.

[0033] Preferably, the heat sink 22 has a ventilation slot 222 between two adjacent conveying channels 221, so that airflow can pass through the ventilation slot 222 to carry away the heat on the surface of the conveying channel 221 and promote heat dissipation.

[0034] Preferred, such as Figure 4 As shown, the connection ends of the connecting pipe 21 and the arc-shaped connecting pipe 23 to the heat sink 22 are flat and constricted, and transition along a smooth curve to fit the channel diameter of the delivery channel 221 and reduce the resistance to the flow of liquid.

[0035] Furthermore, a heat dissipation fin 231 is provided inside the arc-shaped connecting pipe 23. The heat dissipation fin 231 bends synchronously with the path of the arc-shaped connecting pipe 23. When the coolant flows through the arc-shaped connecting pipe 23, the heat dissipation fin 231 can absorb the heat of the liquid at the center of the coolant to assist in heat dissipation.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
