Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts and coolers, specifically to a high-efficiency three-dimensional heat dissipation cooler. Background Technology

[0002] In the automotive parts industry, oil coolers are commonly referred to as engine oil coolers. Their main function is to control the temperature of engine lubricating oil, preventing it from deteriorating due to high temperatures and ensuring stable lubrication performance. Engine oil coolers can be classified into air-cooled and water-cooled types based on the cooling medium. Air-cooled coolers rely on the airflow from the vehicle's direction of travel for cooling; they have a simple structure but depend on ventilation conditions. Water-cooled coolers, on the other hand, exchange heat through the circulation of engine coolant, offering more precise temperature control.

[0003] Regarding water cooling technology, we know that improving heat dissipation efficiency within a limited space is crucial. Existing coolers employ a simple heat dissipation fin structure. Utility Model Content

[0004] In order to solve the technical problems and shortcomings of the prior art, the present invention provides a high-efficiency three-dimensional heat dissipation cooler, which can further improve cooling efficiency and facilitate processing and production.

[0005] To achieve the above and other related objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency three-dimensional heat dissipation cooler includes a mounting plate, a first-layer plate, a stacked unit, and a tail-layer plate that are fixedly connected in sequence. There is at least one stacked unit, which includes fins, a first intermediate plate, and a second intermediate plate. The mounting plate is provided with water inlet and outlet and oil inlet and outlet. The mounting plate is fixed to the first-layer plate. The outer periphery of the first-layer plate, the first intermediate plate, the second intermediate plate, and the tail-layer plate are provided with flanges, and they are stacked in sequence and fixed to each other by welding the flanges to form multiple sandwich spaces. Fins are provided in each sandwich space. Each sandwich space has one water inlet and outlet and the next layer is connected to the oil inlet and outlet.

[0007] The fins are formed into a heat dissipation screen body by bending and stamping the sheet metal. The heat dissipation screen body includes a top plate, an upper folded foot, a bottom plate, and a lower folded foot. The top plate and the bottom plate are provided with slots that are staggered from left to right. The bottom of the slot of the top plate is connected to both sides of the bottom plate through the lower folded foot, and the two sides of the top plate are connected to the bottom of the slot of the bottom plate through the upper folded foot.

[0008] Preferably, the upper folding foot, the top plate, and the lower folding foot form a trapezoidal profile.

[0009] Preferably, the fins are provided with clearance holes.

[0010] Preferably, a connecting structure is provided at the location of the avoidance cut hole. The connecting structure includes a concave ring and an upper convex ring, and the two spaced interlayer spaces are connected by the fixed connection of the concave ring and the upper convex ring.

[0011] Preferably, one side of the fin is provided with a flow-through slit, the flow-through slit is far away from the clearance cut for water passage, and the flow-through slit is spaced from the side wall of the interlayer space.

[0012] Preferably, the tail plate is provided with a plug, and the tail plate is welded and fixed to the stacked unit by the plug and used to close the bottom of the stacked unit. An auxiliary plate is also welded and fixed to the bottom of the tail plate.

[0013] Preferably, the mounting plate is further provided with positioning holes, which are located between the two water inlets and outlets and between the two oil inlets and outlets.

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

[0015] 1. This utility model forms multiple sandwich spaces through a stacking method, with fins installed in each sandwich space. The fin structure is designed three-dimensionally, allowing for more uniform and thorough contact between the fins and water or oil. The sandwich spaces are interconnected by using one oil space and one water space, achieving isolation between water and oil while allowing them to come into close proximity. Through heat conduction of the stacked units, the heat from the oil is evenly and closely transferred to the water. Since both water and oil are circulating, they undergo thorough and uniform heat exchange within this cooler, resulting in highly efficient cooling of the oil. The stacked and welded fixing method makes assembly and production very easy, improving assembly and production efficiency. In particular, the fin structure design, with its upper and lower layers, while increasing resistance to water flow, results in more uniform contact with the water. The heat dissipation screen allows the water to move up and down, further improving heat dissipation efficiency.

[0016] 2. In this utility model, to facilitate the processing of the fins, a trapezoidal outline is designed to facilitate bending and prevent breakage at the crease during bending. The avoidance cut holes provide space for the connecting structure, which in turn enables the isolation of the water and oil interlayer spaces and the connection of multiple water and oil layers.

[0017] 3. Setting up flow-through cut edges and leaving gaps can reduce water flow resistance and increase water flow velocity;

[0018] 4. Positioning holes can improve the positioning accuracy during welding operations.

[0019] Other additional advantages and benefits of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0031] Example:

[0032] This invention discloses a highly efficient three-dimensional heat dissipation cooler, as described in the embodiments below. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the system includes a mounting plate 1, a first-layer plate 2, a stacked unit 3, and a tail-layer plate 4, which are sequentially and fixedly connected to each other. There is at least one stacked unit 3, which includes a fin 31, a first intermediate plate 32, and a second intermediate plate 33. A fin 31 is disposed between the first intermediate plate 32 and the first-layer plate 2, and another fin 31 is disposed between the first intermediate plate 32 and the second intermediate plate 33. Similarly, multiple subsequent stacked units 3 are stacked according to the required amount of oil to be cooled, thus meeting various oil cooling needs.

[0033] The mounting plate 1 is provided with water inlet / outlet 5 and oil inlet / outlet 6. In this design, there are two water inlet / outlet 5, one as the water inlet and the other as the water outlet. Similarly, the oil inlet / outlet 6 is also provided with two water inlet / outlet 6.

[0034] Mounting plate 1 is fixed to the first-layer plate 2. The outer periphery of the first-layer plate 2, intermediate plate 1 32, intermediate plate 2 33, and tail plate 4 are provided with flanges 7, and they are stacked sequentially and welded together through the flanges 7 to form multiple interlayer spaces 8. Each interlayer space 8 is equipped with fins 31, and each interlayer space 8 has one water inlet / outlet 5 connected to it, while the next layer connects to the oil inlet / outlet 6. In this design, the fixing method is welding, specifically ultrasonic welding. The contact points between the first-layer plate 2, intermediate plate 1 32, intermediate plate 2 33, and tail plate 4 in this design can be fixed and sealed using ultrasonic welding.

[0035] In this scheme, combined with Figure 2 and Figure 5 As shown, the fins 31 are formed into a heat dissipation screen body 9 by bending and stamping the sheet metal. The heat dissipation screen body 9 includes a top plate 91, an upper folding foot 92, a bottom plate 93, and a lower folding foot 94; the top plate 91 and the bottom plate 93 are provided with slots 95 that are staggered from left to right, the bottom of the slot 95 of the top plate 91 is connected to both sides of the bottom plate 93 through the lower folding foot 94, and the two sides of the top plate 91 are connected to the bottom of the slot 95 of the bottom plate 93 through the upper folding foot 92.

[0036] The working principle of this scheme is as follows: multiple mezzanine spaces are formed through layering, combined with... Figure 4 and Figure 5 Understanding the design, fins 31 are installed within each interlayer space 8. The three-dimensional design of the fins 31 allows for more uniform and thorough contact with water or oil. The interconnected interlayer spaces 8 utilize a layer of oil space and a layer of water space, achieving both water and oil isolation while allowing them to approach each other closely. Through heat conduction in the stacked unit 3, the heat from the oil is evenly and closely transferred to the water. Since both water and oil are circulating, they undergo thorough and uniform heat exchange within this cooler, resulting in highly efficient cooling of the oil. The stacked welding method facilitates easy assembly and production, improving assembly and production efficiency. In particular, the structural design of the fins 31, with its layered structure, while increasing resistance to water flow, results in more uniform contact with the water. The heat dissipation screen 9 allows the water to move vertically, further enhancing heat dissipation efficiency.

[0037] exist Figure 5 As can be seen, the upper folding foot 92, the top plate 91, and the lower folding foot 94 form a trapezoidal profile 96. To facilitate the processing of the fins 31, the trapezoidal profile 96 is designed to facilitate bending and prevent breakage at the crease during bending. The avoidance hole 311 provides space for the connecting structure 10. The connecting structure 10 is used to achieve the isolation of the water and oil interlayer spaces 8 and the connection of multiple water spaces and multiple oil spaces.

[0038] For ease of installation, the fin 31 is provided with a clearance cut 311. A connecting structure 10 is provided at the location of the clearance cut 311. The connecting structure 10 includes a concave ring 101 and an upper convex ring 102. The two spaced interlayer spaces 8 are connected by the fixed connection of the concave ring 101 and the upper convex ring 102.

[0039] exist Figure 4 In the middle, one side of the fin 31 is provided with a flow-through cut edge 312. The flow-through cut edge 312 is far away from the avoidance cut hole 311 used for water passage, and a distance L is left between the flow-through cut edge 312 and the side wall of the interlayer space 8. The flow-through cut edge 312 and the distance L can reduce water flow resistance and increase water flow velocity.

[0040] To improve structural reliability and bottom structural strength, the tail plate 4 is provided with a plug head 111. The tail plate 4 is welded and fixed to the stacked unit 3 via the plug head 111 and is used to seal the bottom of the stacked unit 3. An auxiliary plate 110 is also welded and fixed to the bottom of the tail plate 4. In this way, the tail plate 4 can resist impact and deformation.

[0041] The mounting plate 1 is also provided with positioning holes 11, which are located between the two water inlets / outlets 5 and the two oil inlets / outlets 6. The positioning holes 11 can improve the positioning accuracy during welding operations.
