Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive radiator technology, and more specifically, to an automotive radiator assembly with multi-layer heat pipes. Background Technology
[0002] During vehicle operation, components such as the engine generate a large amount of heat. The radiator assembly is crucial for maintaining its normal operating temperature. As the core device that ensures the normal operating temperature of key components such as the car engine, the automotive radiator assembly occupies a pivotal position in the automotive cooling system. With the rapid development of the automotive industry, engine power is constantly increasing and vehicle operating conditions are becoming more complex. This has led to a sharp increase in the heat generated by components such as the engine during operation, placing higher demands on the heat dissipation performance of the radiator assembly.
[0003] Utility model patent CN220288295U discloses an automotive radiator with multi-layer heat dissipation pipes, belonging to the field of automotive radiator technology. Its key technical features include a housing with mesh screens installed on the front and rear sides of the inner side. A double-layer pipe assembly is installed on the inner side of the housing. A fan is located at the bottom right side of the housing, and a duct is connected to the fan's outlet. The housing supports and mounts the internal structure. Compared to single-row pipes, the double-layer pipe assembly provides better heat dissipation. Coolant is injected through the inlet, and the heat dissipation layer pipes and branch pipes, in conjunction with the cooling fan, exchange heat with the surrounding air. The coolant is then discharged through the outlet into the vehicle's cooling system's pump, water tank, and heat exchanger for recycling. When heat accumulates in the heat dissipation layer pipes and is difficult to dissipate, it also operates through the branch pipes to prevent malfunction.
[0004] While this technical solution offers the advantage of multi-layer heat dissipation, most radiator assemblies with multi-layer heat pipes still rely excessively on the vehicle's own cooling system for coolant delivery during actual use. This over-reliance on the vehicle's own coolant supply increases the burden on the vehicle's refrigeration system and raises energy consumption. Therefore, we propose a multi-layer heat pipe automotive radiator assembly. Utility Model Content
[0005] The purpose of this invention is to provide an automotive radiator assembly with multi-layer heat pipes to address the deficiencies mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A multi-layer heat pipe automotive radiator assembly includes a heat insulation cover, the upper and lower ends of which are connected to the outside. Multiple sets of cooling copper pipes containing coolant are fixedly installed on one inner wall of the heat insulation cover. External heat dissipation ends of the cooling copper pipes extend through the other side of the heat insulation cover and are located outside the heat insulation cover. Multiple heat dissipation fins are fixedly installed on the external heat dissipation ends. A cooling component for introducing coolant for cooling is provided inside the top shell of the heat insulation cover. The cooling component includes a serpentine heat exchange tube disposed within the heat insulation cover. An air intake component is provided at the bottom of the heat insulation cover.

[0008] Preferably, the heat insulation cover is provided with an inner cavity, and both the upper and lower ends of the inner cavity are connected to the outside.
[0009] Preferably, the cooling copper pipes are inclined upwards at 30° to 45° for the return of the condensed coolant, and adjacent sets of cooling copper pipes are arranged alternately.

[0012] Preferably, a support frame is fixedly installed on the inner wall of the air inlet shroud, and a fan cover is fixedly installed on the outside of the fan, with the fan cover fixedly installed on the support frame;
[0013] This setting facilitates the fan assembly process.
[0014] Preferably, an inlet pipe and an outlet pipe are fixedly installed at both ends of the serpentine heat exchange tube, and both the inlet pipe and the outlet pipe extend out of the heat insulation cover;
[0015] This setup allows the inlet and outlet pipes to be connected to the vehicle's circulating cooling system, utilizing the vehicle's built-in pump, water tank, and heat exchanger for coolant recycling.
[0016] Preferably, a dust filter assembly is provided at the bottom of the air inlet hood, the dust filter assembly including a filter screen, the filter screen having a serrated cross-section;

[0018] Preferably, a fixing ring is fixedly installed on the bottom housing of the air inlet hood, the dust filter assembly further includes an air inlet duct, the filter screen is fixedly installed on the inner wall of the air inlet duct, and a limiting ring is fixedly installed on the top housing of the air inlet duct, the limiting ring being detachably installed on the bottom surface of the fixing ring;
[0019] This setting facilitates the assembly of the air inlet duct.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] 1. This utility model sets up multiple sets of cooling copper pipes that internally store coolant. The cooling copper pipes are inclined upwards and arranged in an alternating manner. With the ventilation gap between adjacent copper pipes, the coolant can effectively flow back in the pipes. At the same time, it increases the contact area with air, promotes heat exchange, and achieves the purpose of improving the heat exchange effect of the cooling copper pipes and quickly reducing heat. Moreover, this process does not require the vehicle's refrigeration system and will not increase the cooling burden of the vehicle system.
[0022] 2. This utility model, by setting an air intake component at the bottom of the heat insulation cover, uses symmetrical fans inside the air intake cover to send outside air into the heat insulation cover, which flows through the cooling copper pipe, thereby reducing the temperature of the surrounding air, enhancing the heat dissipation capacity of the radiator component, and ensuring that the key components of the car operate at a suitable temperature.
[0023] 3. This utility model achieves the circulation of coolant by setting a serpentine heat exchange tube with a cooling component at the top of the heat insulation cover, which is connected to the vehicle's circulating cooling system in conjunction with the liquid inlet and outlet pipes. This continuously removes heat. At the same time, the dust filter component at the bottom of the air inlet cover increases the filtration area with a serrated filter screen, reducing the amount of dust entering the heat insulation cover. This ensures the cleanliness of the coolant, extends the service life of the radiator components, and stabilizes the heat dissipation performance. Attached Figure Description

[0032] 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.
[0033] Please see Figures 1-3 This utility model provides a technical solution: a multi-layer heat pipe automotive radiator assembly, including a heat insulation cover 1, the upper and lower ends of which are connected to the outside. Specifically, the heat insulation cover 1 is provided with an inner chamber 10, the upper and lower ends of which are connected to the outside, so that air can circulate smoothly and form a good heat dissipation channel.
[0034] like Figure 1 and Figure 2 As shown, multiple sets of cooling copper pipes 11 containing coolant are fixedly installed on one inner wall of the heat insulation cover 1. The external heat dissipation end 111 of the cooling copper pipe 11 extends out of the other side plate of the heat insulation cover 1 and is located outside the heat insulation cover 1. Multiple heat dissipation fins 112 are fixedly installed on the external heat dissipation end 111. The coolant in the cooling copper pipe 11 can absorb the surrounding heat to reduce the temperature inside the heat insulation cover 1. The coolant after absorbing heat will evaporate to the external heat dissipation end 111 and dissipate the heat from the external heat dissipation end 111 with the help of the heat dissipation fins 112. Afterward, the evaporated coolant will continue to condense due to the temperature drop and flow back to the bottom of the cooling copper pipe 11, realizing the cyclic cooling operation.
[0035] like Figure 1 and Figure 2As shown, the cooling copper pipes 11 are inclined upwards at 30°~45° for the return of condensed coolant. The two sets of cooling copper pipes 11 are staggered, and ventilation gaps 113 are provided between each pair of adjacent cooling copper pipes 11. The distance between two sets of cooling copper pipes 11 is between 3cm and 6cm, which allows the condensed coolant to return smoothly, increases the contact area between the cooling copper pipes 11 and the air, promotes heat exchange between the air and the coolant, and allows heat to be dissipated into the air more quickly, which significantly improves the heat dissipation efficiency of the cooling copper pipes 11.
[0036] In this embodiment, a cooling component 4 for introducing coolant for cooling is provided inside the top shell of the heat insulation cover 1. The cooling component 4 includes a serpentine heat exchange tube 40 installed inside the heat insulation cover 1. An inlet pipe 41 and an outlet pipe 42 are fixedly installed at both ends of the serpentine heat exchange tube 40, respectively. Both the inlet pipe 41 and the outlet pipe 42 extend out of the heat insulation cover 1 and can be connected to the vehicle's circulating cooling system. The coolant is circulated using the vehicle's own liquid pump, water tank, and heat exchanger to achieve further heat dissipation when needed. The connection of the inlet pipe 41 and the outlet pipe 42 to the vehicle's circulating cooling system is a conventional technology and will not be described in detail here.
[0037] like Figure 1 As shown, the bottom of the heat insulation cover 1 is provided with an air inlet assembly 2. The air inlet assembly 2 includes an air inlet cover 20 fixedly installed at the bottom of the heat insulation cover 1. Inside the air inlet cover 20 are two symmetrical fans 23, which promote airflow and heat dissipation by using the fans 23.
[0038] like Figure 1 As shown, a support frame 21 is fixedly installed on the inner wall of the air inlet shroud 20, and a fan cover 22 is fixedly installed on the outside of the fan 23. The fan cover 22 is fixedly installed on the support frame 21 by multiple fastening screws, which facilitates the fixed installation operation.
[0039] like Figure 1 As shown, a dust filter assembly 3 is provided at the bottom of the air inlet shroud 20. The dust filter assembly 3 includes a filter screen 32. The cross-section of the filter screen 32 is serrated, which can increase the filtration area of the filter screen 32 and reduce the amount of dust and other impurities blown into the heat insulation shroud 1. This further ensures the cleanliness of the surface of the cooling copper tube 11 and the serpentine heat exchange tube 40, which is beneficial to ensuring the heat exchange effect of the subsequent cooling copper tube 11 and the serpentine heat exchange tube 40.
[0040] like Figure 1As shown, a fixing ring 24 is fixedly installed on the bottom housing of the air inlet hood 20. The dust filter assembly 3 also includes an air inlet duct 30. The filter screen 32 is fixedly installed on the inner wall of the air inlet duct 30. A limiting ring 31 is fixedly installed on the top housing of the air inlet duct 30. The limiting ring 31 is detachably installed on the bottom surface of the fixing ring 24 by multiple fastening screws, which facilitates the assembly operation of the air inlet duct 30.
[0041] When using the multi-layer heat pipe automotive radiator assembly of this utility model, first connect the inlet pipe 41 and the outlet pipe 42 to the vehicle's circulating cooling system to achieve coolant circulation using the vehicle's own equipment. After starting the car, the air intake assembly 2 starts to work, and the symmetrical fans 23 inside the air intake shroud 20 operate. Under the action of the fans 23, the outside air passes through the sawtooth filter screen 32 inside the air intake duct 30 to filter dust and impurities before entering the inner chamber 10 of the heat insulation cover 1.
[0042] At this time, the coolant in the multiple sets of cooling copper pipes 11 on the inner wall of one side of the heat insulation cover 1 absorbs the surrounding heat, thereby reducing the temperature inside the heat insulation cover 1. The coolant that has absorbed heat and evaporated rises to the external heat dissipation end 111 and dissipates the heat to the flowing air through the heat dissipation fins 112. As the heat is dissipated, the temperature of the coolant decreases and it condenses. The condensed coolant flows smoothly back to the bottom of the cooling copper pipes 11, completing the cycle of cooling.
[0043] When a vehicle generates a large amount of heat during operation, and the cooling copper pipe 11 alone is insufficient to dissipate the heat, the coolant in the vehicle's circulating cooling system flows into the serpentine heat exchange pipe 40 through the inlet pipe 41. After further absorbing heat in the heat insulation cover 1, it flows back to the system through the outlet pipe 42, thereby enhancing heat dissipation and ensuring that the key components of the vehicle are at a suitable temperature.
[0044] 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. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
