Description

Technical Field

[0001] This utility model relates to automotive cooling devices, and more particularly to a cast aluminum crimped intercooler. Background Technology

[0002] The automotive intercooler is a heat exchanger. Traditional all-aluminum intercoolers typically seal the water chamber and core by welding the main plate and water chamber together using methods such as argon arc welding. This requires high precision in the welding process to ensure the sealing and pressure resistance of the joints. Currently, the most widely used structure in China is the aluminum-plastic structure, which consists of an aluminum core and a plastic water chamber. However, intercoolers using plastic water chambers have far inferior anti-aging and corrosion resistance and heat dissipation efficiency compared to all-aluminum intercoolers. Furthermore, during heat exchange, the core and water chamber are subjected to vehicle vibrations over a long period, which can lead to a certain possibility of loosening of the clamping structure between the core and water chamber. Both of these methods carry a high risk of coolant leakage. Moreover, aluminum cores and plastic water chambers are not easily reinforced by welding the clamping structure, making it impossible to improve the stability of the clamping structure. Summary of the Invention

[0003] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a cast aluminum crimped intercooler to solve the problems of low stability and high risk of coolant leakage in the existing automotive intercooler crimped structure.

[0004] A cast aluminum crimped intercooler includes: a main plate and two water chambers, with the main plate located between the two water chambers; The water chamber is equipped with an open mouth chamber, a connecting pipe and a protrusion. The protrusion is located at the end of the water chamber closest to the main plate and protrudes horizontally out of the outside of the water chamber. The main plate is provided with a cooling pipe, a slot and a fastening part. Two slots are recessed vertically on the top and bottom surfaces of the main plate, respectively. The slots are suitable for engaging the protrusion. At least two fastening parts are evenly arranged on the outside of the slots. After the fastening parts are bent and deformed, they abut against the protrusion, so that the two open chambers abut against the top and bottom surfaces of the main plate, respectively. The open chambers, the connecting pipe and the cooling pipe are connected.

[0005] Preferably, the material of at least the protrusion in the water chamber is aluminum, and the material of at least the fastening part of the main piece is aluminum. When the fastening part abuts against the protrusion, there is a gap between the edge of the fastening part and the protrusion that can be welded.

[0006] Preferably, the inner wall of the card slot is made of aluminum, and there is a gap between the inner wall of the card slot and the protrusion for welding.

[0007] Preferably, the cast aluminum crimped intercooler also includes a sealing element, with a sealing element provided between the two protrusions and the bottom surface of the slot, and the protrusions contacting the slot through the sealing element.

[0008] Preferably, the shape of the slot corresponds to the protrusion, so that when the protrusion is located in the slot, the outer side of the protrusion fits against the inner wall of the slot.

[0009] Preferably, the cooling pipe, slot, and fastening part of the main piece are integrally formed.

[0010] Preferably, the cooling pipe, slot, and fastening part of the main piece are all made of aluminum.

[0011] Preferably, the open cavity of the water chamber, the connecting pipe, and the protrusion are integrally formed by a cast aluminum process.

[0012] Preferably, the main plate also includes a heat dissipation strip, the outside of the cooling pipe is in contact with the heat dissipation strip, and the heat dissipation strip is fixedly installed on the outside of the cooling pipe in a wavy shape.

[0013] Preferably, both the protrusion and the slot are rectangular.

[0014] Beneficial effects: 1. After all the fastening parts on the main plate are bent and deformed, they are fastened to the protrusions of the water chamber. Since all the fastening parts on the main plate have a certain degree of plasticity, the fastening parts on the main plate can be kept against the protrusions of the water chamber to keep the water chamber, the seal and the main plate tightly fitted and sealed. Since the material of the protrusion, fastening parts and the slot is aluminum, the fastening parts are bent and deformed and then abut against the protrusions. The protrusions and fastening parts are welded and reinforced by welding equipment to enhance the stability of the connection between the main plate and the water chamber.

[0015] 2. Welding can also be performed along the edges of the fastening part and the slot using welding equipment to completely seal the edge of the connection between the main plate and the water chamber, further enhancing the stability of the connection between the main plate and the water chamber. In case of leakage at the seal, the weld at the connection between the main plate and the water chamber can block the coolant from leaking out, further reducing the risk of coolant leakage.

[0016] 3. To improve the pressure resistance and thermal conductivity of the water chamber, the open cavity, connecting pipe and protrusion of the water chamber are integrally formed. In particular, the open cavity, connecting pipe and protrusion of the water chamber are integrally formed by aluminum casting process. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figures 1-5 As shown, a cast aluminum crimped intercooler includes: a main plate 10 and two water chambers 20, one water chamber 20 being connected to a coolant supply end and the other water chamber 20 being connected to a coolant recovery end, with the main plate 10 located between the two water chambers 20; each water chamber 20 is provided with an open cavity 21, a connecting pipe 22, and a protrusion 23, the protrusion being located at the end of the water chamber 20 closest to the main plate 10, and the protrusion 23 protruding horizontally outward from the outside of the water chamber 20; the main plate 10 is provided with a cooling pipe 11, a heat dissipation strip 12, and a slot 13. The outer side of the cooling pipe 11 contacts the heat dissipation strip 12, which is fixedly installed on the outer side of the cooling pipe 11. Two slots 13 are recessed vertically into the top and bottom surfaces of the main plate 10, respectively. The slots 13 are adapted to engage with the protrusion 23. At least two fastening parts 14 are evenly arranged on the outer side of the slots 13. After the fastening parts 14 are bent and deformed, they abut against the protrusion 23, so that the two open chambers 21 abut against the top and bottom surfaces of the main plate 10, respectively. The open chambers 21, the connecting pipe 22 and the cooling pipe 11 are connected.

[0029] The car's cooling system introduces coolant into one of the water chambers 20. The coolant flows through the main plate 10 and is then discharged through the other water chamber 20. As the coolant flows through the main plate 10, it is transported through the cooling pipes 11 on the main plate 10. The flowing coolant cools the heat sink 12 and the cooling pipes 11. Before the air is sent into the engine, it passes through the main plate 10. The air comes into contact with the heat sink 12 and the cooling pipes 11 on the main plate 10, and the heat sink 12 and the cooling pipes 11 work together to cool the air.

[0030] like Figure 6 As shown, when the water chamber 20 is snapped onto the main plate 10, two lower brackets support the main plate 10 that needs to be snapped onto the water chamber 20. A sealing element 30 is placed in the slot 13 of the main plate 10. The water chamber 20 is then placed into the slot 13 of the main plate 10. The worker then controls the extension rod of the cylinder 41 to extend and press the water chamber 20 through the pressure plate 42, ensuring a tight seal between the water chamber 20 and the main plate 10. While pressing the water chamber 20, the drive component drives the snap-tooth arms 50 on both sides of the main plate 10 according to the stroke adjusted by the snap-tooth spacing of the main plate 10, pressing the snap-fit ​​portion 14 on the main plate 10. When it is necessary to adjust the snap-fit ​​portion 14 on other sides... During bending, adjust the spacing between the two lower brackets, reinsert the initially fastened water chamber 20 and main plate 10, and then press and bend the fastening parts 14 on the other sides. After all the fastening parts 14 on the main plate 10 are bent and deformed, they are fastened to the protrusion 23 of the water chamber 20. Since all the fastening parts 14 on the main plate 10 have a certain degree of plasticity, the fastening parts 14 on the main plate 10 can remain against the protrusion 23 of the water chamber 20 to keep the water chamber 20 and the main plate 10 tightly fitted and sealed. Then, the worker controls the telescopic rod of the cylinder 41 to retract and stop pressing the water chamber 20, and takes out the fastened water chamber 20 and main plate 10.

[0031] More preferably, such as Figure 1 and Figure 5 As shown, at least the protrusion 23 in the water chamber 20 is made of aluminum, and at least the fastening part 14 and the slot 13 of the main piece 10 are made of aluminum. When the fastening part 14 abuts against the protrusion 23, there is a gap between the edge of the fastening part 14 and the protrusion 23 that can be welded.

[0032] Since the protrusion 23, the fastening part 14, and the slot 13 are made of aluminum, the fastening part 14 is bent and deformed and abuts against the protrusion 23. The protrusion 23 and the fastening part 14 are welded and reinforced by welding equipment, thereby strengthening the stability of the connection between the main plate 10 and the water chamber 20. Welding equipment can also be used to weld along the edge of the fastening part 14 and the slot 13 to completely seal the edge of the connection between the main plate 10 and the water chamber 20, further strengthening the stability of the connection between the main plate 10 and the water chamber 20. In the event of leakage between the main plate 10 and the water chamber 20, the weld at the connection between the main plate 10 and the water chamber 20 can block the coolant from leaking out, further reducing the risk of coolant leakage.

[0033] More preferably, such as Figure 1 , Figures 3-5 As shown, the slot 13 includes an inner wall, and the shape of the slot 13 corresponds to the protrusion 23, so that when the protrusion 23 is located in the slot 13, the outer side of the protrusion 23 fits against the inner wall of the slot 13.

[0034] After the fastening or welding is completed, the inner wall of the slot 13 can support the protrusion 23, improving the connection stability between the water chamber 20 and the main plate 10.

[0035] More preferably, both the protrusion 23 and the slot 13 are rectangular.

[0036] The main plate 10 is typically equipped with several horizontally arranged cooling pipes 11. The horizontally arranged cooling pipes 11 are located inside the slot 13, using a rectangular protrusion 23 and slot 13, which makes the intercooler structure more compact and ensures that the coolant in the water chamber 20 flows evenly into the cooling pipes 11. More preferably, the cast aluminum crimped intercooler also includes a sealing element 30. A sealing element 30 is provided between the two protrusions 23 and the bottom surface of the slot 13. The sealing element 30 can be a rubber strip with the same size and shape as the bottom surface of the slot 13. The protrusions 23 contact the slot 13 through the sealing element 30, and the outer side of the protrusions 23 fits against the inner wall of the slot 13.

[0037] When the fastening part 14 on the main plate 10 can be held against the protrusion 23 of the water chamber 20, the protrusion 23 and the groove 13 together squeeze the sealing member 30 to keep the water chamber 20, the sealing member 30 and the main plate 10 tightly fitted and sealed. The sealing member 30 fills the gap between the water chamber 20 and the main plate 10 to enhance the sealing between the water chamber 20 and the main plate 10.

[0038] More preferably, in order to improve the compressive strength of the main sheet 10, the cooling pipe 11, the slot 13 and the fastening part 14 of the main sheet 10 are integrally formed, and the cooling pipe 11, the slot 13 and the fastening part 14 of the main sheet 10 are all made of aluminum.

[0039] More preferably, in order to improve the pressure resistance and thermal conductivity of the water chamber 20, the open cavity 21, the connecting pipe 22 and the protrusion 23 of the water chamber 20 are integrally formed, and in particular, the open cavity 21, the connecting pipe 22 and the protrusion 23 of the water chamber 20 are integrally formed by aluminum casting process.

[0040] More preferably, such as Figure 4 As shown, in order to cool the air that needs to be supplied to the engine more efficiently, the heat dissipation sash 12 is fixedly installed on the outside of the cooling pipe 11 in a wave shape.

[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
