Description

Technical Field

[0001] This utility model relates to the field of automotive radiator technology, specifically to a cooling device for automobiles. Background Technology

[0002] The car radiator is part of the car cooling system and consists of three parts: the inlet chamber, the outlet chamber, and the radiator core.

[0003] For example, Chinese utility model patent CN211950649U, entitled "A Car Radiator with Good Heat Dissipation Effect," includes an upper water chamber, a lower water chamber, a housing, and cooling pipes. The upper and lower water chambers are located at the top and bottom of the housing, respectively, and the cooling pipes are located inside the housing and extend beyond the top and bottom. This device cools the coolant inside the cooling pipes using the coolant inside the housing. Simultaneously, through the design of auxiliary components, the coolant inside the housing can be agitated. Furthermore, because the coolant flows in different directions within the cooling pipes, the multiple agitator rods can rotate in different directions, ensuring thorough agitation of the coolant inside the housing. This allows for better contact between the coolant inside the housing and the surface of the cooling pipes, thus improving the cooling effect of the engine and ensuring its normal operation.

[0004] In the existing technology, when the coolant flows through the cooling pipe, it exchanges heat with the coolant in the water tank. Due to the influence of the size and specifications of the cooling pipe, the effective heat exchange area that can carry out heat exchange is only the unfolded area of ​​the side wall of the pipe. This results in a small heat exchange area between the high-temperature coolant in the cooling pipe and the coolant in the water tank, and low heat exchange efficiency. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a heat dissipation device for automobiles, which solves the technical problem of low heat exchange efficiency caused by the small area on which high-temperature coolant can exchange heat with the coolant in the water tank when it flows through the cooling pipe.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a heat dissipation device for automobiles, comprising:

[0008] A heat exchanger having at least two first cavity layers and at least two second cavity layers that are spaced apart and staggered; and

[0009] The connecting component includes a first connecting member and a second connecting member. The first connecting member has a first liquid inlet and a first liquid outlet, which are respectively connected to at least two first cavity layers.

[0011] In some embodiments, the number of heat exchange protrusions is multiple, and the multiple heat exchange protrusions are distributed in an array along the inner wall of the first cavity layer.

[0012] In some embodiments, the volume of the first cavity layer is larger than the volume of the second cavity layer.

[0013] In some embodiments, the first connecting member includes a first liquid inlet and a first liquid outlet, the first liquid inlet and the first liquid outlet being connected to the heat exchanger and respectively connected to at least two first cavity layers.

[0014] In some embodiments, the second connecting member includes a second liquid inlet and a second liquid outlet, the second liquid inlet and the second liquid outlet being connected to the heat exchanger and respectively connected to at least two second cavity layers.

[0015] In some embodiments, the heat exchanger contains multiple first cavity layers and multiple second cavity layers, which are arranged alternately along the height direction of the heat exchanger.

[0016] In some embodiments, the interior of the first liquid inlet and the first liquid outlet are respectively formed with a first connecting hole and a plurality of first connecting grooves, the plurality of first connecting grooves being connected to the first connecting hole, the first connecting grooves being correspondingly arranged and connected to the first cavity layer, the interior of the second liquid inlet and the second liquid outlet are respectively formed with a second connecting hole and a plurality of second connecting grooves, the plurality of second connecting grooves being connected to the second connecting hole, the second connecting grooves being correspondingly arranged and connected to the second cavity layer, and the diameter of the second connecting hole being smaller than the diameter of the first connecting hole.

[0017] In some embodiments, the circumferential inner wall of the first connecting hole is formed with a first internal thread, and the first connecting member further includes two first connectors, the circumferential outer wall of the first connectors is provided with a first external thread, and the two first connectors are respectively threaded to the two first connecting holes.

[0018] In some embodiments, the circumferential inner wall of the second connecting hole is formed with a second internal thread, and the second connecting member further includes two second connectors, the circumferential outer wall of the second connectors is provided with a second external thread, and the two second connectors are respectively threaded to the two second connecting holes.

[0019] Compared with the prior art, the beneficial effects of the heat dissipation device for automobiles provided by this utility model include: the heat exchanger has at least two first cavity layers and at least two second cavity layers that are spaced apart and staggered, which are used to temporarily store coolant and high-temperature water, respectively, so that the coolant and high-temperature water can exchange heat when they come into contact with the sidewalls between the first cavity layer and the second cavity layer, the interior of the first connecting member is connected to the interior of the first cavity layer, and the interior of the second circulation member is connected to the interior of the second cavity layer, which are used to realize the entry and exit of coolant and high-temperature water, respectively.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] To address the technical problem of low heat exchange efficiency in existing technologies due to the small area available for heat exchange between the high-temperature coolant flowing through the cooling pipe and the coolant in the water tank, this invention provides a heat dissipation device for automobiles. This device utilizes a heat exchanger 100 with staggered first cavity layers 110 and second cavity layers 120, and employs first connecting members 210 and 220 to allow the inlet and outlet of coolant and high-temperature water, respectively. The effective heat exchange area between the coolant and the high-temperature water is the area of ​​the sidewall between the first cavity layers 110 and 120, which is significantly larger than the heat exchange area of ​​the circumferential sidewall of the cooling pipe, thus improving heat exchange efficiency.

[0028] Please see Figures 1 to 4 , Figure 1 This is a schematic diagram of a heat dissipation device for automobiles according to an embodiment of the present invention. The heat dissipation device for automobiles includes a heat exchanger 100 and a connecting component 200. The heat exchanger 100 has at least two first cavity layers 110 and at least two second cavity layers 120 that are spaced apart from each other and distributed in an alternating manner. The connecting component 200 includes a first connecting member 210 and a second connecting member 220. The first connecting member 210 has a first liquid inlet end and a first liquid outlet end, which are respectively connected to at least two first cavity layers 110. The second connecting member 220 has a second liquid inlet end and a second liquid outlet end, which are respectively connected to at least two second cavity layers 120.

[0029] In this device, the heat exchanger 100 has at least two first cavity layers 110 and at least two second cavity layers 120 that are spaced apart from each other and distributed in an alternating manner. These are used to temporarily store coolant and high-temperature water, respectively, so that the coolant and high-temperature water can exchange heat when they come into contact with the sidewalls between the first cavity layer 110 and the second cavity layer 120. The interior of the first connecting member 210 is connected to the interior of the first cavity layer 110, and the interior of the second circulation member is connected to the interior of the second cavity layer 120, which are used to realize the entry and exit of coolant and high-temperature water, respectively.

[0030] Furthermore, by setting the heat exchanger 100 with staggered first cavity layers 110 and second cavity layers 120, and using the first connecting member 210 and the second connecting member 220 to allow the coolant and high-temperature water to enter and exit respectively, the effective heat exchange area between the coolant and the high-temperature water is the area of ​​the sidewall between the first cavity layer 110 and the second cavity layer 120. Its size is significantly larger than the heat exchange area of ​​the circumferential sidewall of the cooling pipe, which can improve the heat exchange efficiency and solve the technical problem in the prior art that the area where the high-temperature coolant can exchange heat with the coolant in the water tank when flowing through the cooling pipe is small, resulting in low heat exchange efficiency.

[0031] Furthermore, the coolant here is a commercially available and readily procurable device, such as a mixture of ethylene glycol or propylene glycol (approximately 50%) and water, used to cool and reduce the temperature of high-temperature water. The working principle of the radiator here is a conventional setup known to those skilled in the art, and will not be elaborated further here.

[0032] In one embodiment, the heat exchanger 100 is integrally formed from multiple individual heat sinks by stamping, die casting and welding.

[0033] In addition, as one embodiment, the heat exchanger 100 structure is formed by metal 3D printing, which simplifies the process, improves surface accuracy, and reduces production costs, which will not be elaborated further here.

[0034] In this embodiment, the outer wall of the heat exchanger 100 is made of a heat-insulating material, and the partitions inside it used to form at least two first cavity layers 110 and at least two second cavity layers 120 are made of a high thermal conductivity material. The heat-insulating material and the high thermal conductivity material are common and readily available equipment on the market, which are conventional settings known to those skilled in the art, and will not be described in detail here.

[0035] In one embodiment, such as Figures 2 to 4 As shown, the inner wall portion of the first cavity layer 110 protrudes into the second cavity layer 120, forming at least one heat exchange protrusion 130.

[0036] In order to increase the contact area between the coolant and the high-temperature water, at least one heat exchange protrusion 130 is provided on the inner wall of the first cavity layer 110, which can effectively increase the heat exchange area and effectively improve the heat dissipation effect.

[0037] In one embodiment, such as Figure 2 , Figure 3 As shown, there are multiple heat exchange protrusions 130, which are arranged in an array along the inner wall of the first cavity layer 110.

[0038] To further increase the contact area between the coolant and the high-temperature water, multiple heat exchange protrusions 130 are arranged in an array along the inner wall of the first cavity layer 110, which can effectively improve the heat dissipation effect.

[0039] In this embodiment, as Figure 3 , Figure 4 As shown, the volume of the first cavity layer 110 is larger than the volume of the second cavity layer 120.

[0040] The first cavity layer 110 is used to temporarily store coolant, and the second cavity layer 120 is used to temporarily store high-temperature water. By setting the volume of the first cavity layer 110 to be larger than the volume of the second cavity layer 120, the heat exchange efficiency can be further improved by utilizing the effective time.

[0041] In one embodiment, such as Figures 1 to 3 As shown, the first connecting member 210 includes a first liquid inlet 211 and a first liquid outlet 212. The first liquid inlet 211 and the first liquid outlet 212 are respectively connected to the heat exchanger 100 and can be connected to at least two first cavity layers 110 respectively.

[0042] The first inlet section 211 is used to introduce coolant into at least two first cavity layers 110, and the first outlet section 212 is used to discharge coolant from at least two first cavity layers 110.

[0043] In one embodiment, such as Figures 1 to 3 As shown, the second connecting member 220 includes a second liquid inlet 221 and a second liquid outlet 222. The second liquid inlet 221 and the second liquid outlet 222 are respectively connected to the heat exchanger 100 and can be connected to at least two second cavity layers 120 respectively.

[0044] The second liquid inlet 221 is used to introduce high-temperature water into at least two second cavity layers 120, and the second liquid outlet 222 is used to discharge the high-temperature water from at least two second cavity layers 120.

[0045] In one embodiment, such as Figure 3 As shown, the heat exchanger 100 has multiple first cavity layers 110 and multiple second cavity layers 120, which are arranged alternately along the height direction of the heat exchanger 100.

[0046] In order to further increase the contact area between the coolant and the high-temperature water and extend the heat exchange time between the coolant and the high-temperature water, multiple first cavity layers 110 and multiple second cavity layers 120 are arranged alternately along the height direction of the heat exchanger 100.

[0047] Furthermore, the top and bottom of the high-temperature water located in the second cavity layer 120 can contact the coolant located in the two first cavity layers 110, which can effectively increase the contact area between the coolant and the high-temperature water, prolong the heat exchange time between the coolant and the high-temperature water, and improve the heat dissipation efficiency.

[0048] In this embodiment, the interior of the first liquid inlet 211 and the first liquid outlet 212 are respectively formed with a first connecting hole and a plurality of first connecting grooves. The plurality of first connecting grooves are all connected to the first connecting hole. The first connecting grooves are correspondingly arranged and connected to the first cavity layer 110. The interior of the second liquid inlet 221 and the second liquid outlet 222 are respectively formed with a second connecting hole and a plurality of second connecting grooves. The plurality of second connecting grooves are all connected to the second connecting hole. The second connecting grooves are correspondingly arranged and connected to the second cavity layer 120. The diameter of the second connecting hole is smaller than the diameter of the first connecting hole.

[0049] By setting a first connecting hole that is connected to multiple first connecting slots, coolant can enter or exit the first cavity layer 110. By setting a second connecting hole that is connected to multiple second connecting slots, coolant can enter or exit the second cavity layer 120.

[0050] Furthermore, in order to accommodate the fact that the volume of the first cavity layer 110 is larger than that of the second cavity layer 120 and increase the heat exchange efficiency, the diameter of the second connecting hole is smaller than that of the first connecting hole, so that the flow rate of the coolant entering the first cavity layer 110 is greater than the flow rate of the high-temperature water entering the second cavity layer 120, thereby enhancing the heat exchange efficiency.

[0051] In this embodiment, as Figure 2 As shown, the circumferential inner wall of the first connecting hole is formed with a first internal thread, and the first connecting member 210 also includes two first connectors 213. The circumferential outer wall of the first connector 213 is provided with a first external thread, and the two first connectors 213 are respectively threaded to the two first connecting holes.

[0052] The first connector 213 is used to enable communication and circulation between the external coolant and the first cavity layer 110.

[0053] Furthermore, the threaded connection structure makes the connection between the first connector 213 and the heat exchanger 100 detachable, which avoids the inability to remove or deformation of the internal support structure and cavity structure of the heat exchanger 100 due to the processing characteristics of 3D printing.

[0054] In one embodiment, such as Figure 2As shown, the circumferential inner wall of the second connecting hole is formed with a second internal thread, and the second connecting member 220 also includes two second connectors 223. The circumferential outer wall of the second connectors 223 is provided with a second external thread, and the two second connectors 223 are respectively threaded to the two second connecting holes.

[0055] The second connector 223 is used to enable communication and circulation between external high-temperature water and the first cavity layer 110.

[0056] Furthermore, by adopting a threaded structure and combining the process characteristics of 3D printing and CNC machining, the joint strength and roughness can be guaranteed while allowing for supportless printing.

[0057] In addition, in some embodiments, the second connector 223 can be detachably connected to the second liquid inlet 221 and the second liquid outlet 222 by means of elastic snap-fit ​​or abutment, which will not be described in detail here.

[0058] In one embodiment, a positioning hole is also formed in the middle of the heat exchanger 100.

[0059] The positioning hole is used to facilitate the user to install the heat exchanger 100 on the car. The positioning hole penetrates the heat exchanger 100 and is not connected to the first cavity layer 110 and the second cavity layer 120 to avoid leakage of coolant and high-temperature water. Further details are omitted here.

[0060] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below:

[0061] The heat exchanger 100 has at least two first cavity layers 110 and at least two second cavity layers 120 spaced apart and staggered, which are used to temporarily store coolant and high-temperature water, respectively. This allows heat exchange between the coolant and the high-temperature water when they come into contact with the sidewalls between the first cavity layers 110 and 120. The interior of the first connecting member 210 is connected to the interior of the first cavity layer 110, and the interior of the second circulation member is connected to the interior of the second cavity layer 120, respectively, for the entry and exit of coolant and high-temperature water. Compared to the prior art, by setting the heat exchanger 100 with staggered first cavity layers 110 and 120, and using the first connecting member 210 and 220 to allow the entry and exit of coolant and high-temperature water, the effective heat exchange area between the coolant and the high-temperature water is the area of ​​the sidewalls between the first cavity layers 110 and 120, which is significantly larger than the heat exchange area of ​​the circumferential sidewalls of the cooling pipe.

[0062] In the specific working process of this utility model, the first connector 213 is first connected to the first liquid inlet 211 and the first liquid outlet 212 respectively, and the second connector 223 is connected to the second liquid inlet 221 and the second liquid outlet 222 respectively. Then, the coolant enters the first cavity layer 110 through the first connector 213 and the first liquid inlet 211, and the high-temperature water enters the second cavity layer 120 through the second connector 223 and the second liquid inlet 221. Finally, by contacting the inner wall of the heat exchanger 100, heat transfer and heat exchange between the coolant and the high-temperature water can be realized. After the heat exchange is completed, the coolant is discharged from the first cavity layer 110 through the first liquid outlet 212 and the first connector 213, and the high-temperature water is discharged from the second cavity layer 120 through the second liquid outlet 222 and the second connector 223. In this process, not only is the heat exchange area large and the flow rate stable, but there is also sufficient heat exchange time.

[0063] This device, through the aforementioned structure, can improve heat exchange efficiency and solve the technical problem in the prior art where the area for heat exchange between the high-temperature coolant and the coolant in the water tank is small when the coolant flows through the cooling pipe, resulting in low heat exchange efficiency.

[0064] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
