Description

Technical Field

[0001] This invention relates to the field of intercooler technology in commercial vehicle cooling modules, specifically to an intercooler reinforcing block with a limit and anti-loosening feature and its mounting structure. Background Technology

[0002] With the popularization of automotive turbocharging technology and the gradual improvement of national emission standards, the intercooler has gradually become a key component of automobiles. The air after turbocharging is at high temperature and high pressure, and the function of the intercooler is to cool down and depressurize the high temperature and high pressure air before it is input into the engine.

[0003] Because intercoolers operate in a high-temperature and high-pressure environment, their reliability requirements are very high. Currently, the core design of intercoolers involves the heat pipes being directly connected to the main plate. However, as the temperature and pressure inside the intercooler gradually increase, the connection between the heat pipes and the main plate in the existing intercooler core can no longer meet the new reliability requirements. This is mainly reflected in the fact that the connection between the outermost heat pipes and the main plate is prone to cracking, which leads to the failure to meet the reliability requirements.

[0004] In the prior art, a reinforcing block is fitted at the connection position of the heat sink to enhance strength. However, during the brazing process, the impact force of the sprayed flux can drive the reinforcing block into the heat sink, causing it to lose its function of reinforcing the root of the heat sink and easily leading to product scrap. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the above-mentioned technologies by providing a limiting and anti-loosening intercooler reinforcing block and its installation structure, which avoids the sprayed flux from driving the reinforcing block into the heat sink tube, and has good precision and stability, effectively enhancing the strength of the heat sink tube root and its installation structure.

[0006] To achieve the above objectives, the intercooler reinforcing block designed in this invention includes a back plate, which comprises an upper part, a transition part, and a lower part. The width of the lower part of the back plate is smaller than the width of the upper part. The transition part of the back plate is trapezoidal or has arc-shaped sides. Upper liner plates are symmetrically installed on both sides of the upper part of the back plate. The upper edges of the two upper liner plates extend horizontally away from the back plate to form bosses. Lower liner plates are symmetrically installed on both sides of the lower part of the back plate. A transition plate connecting the upper and lower liner plates is installed on the transition part of the back plate.

[0007] Preferably, the maximum width of the reinforcing block located on the two upper liner plates facing the opening direction is greater than the width located at the upper part of the back plate, which facilitates installation.

[0008] Preferably, the width of the reinforcing block located at the lower part of the back plate is smaller than the width located at the upper part of the back plate, which facilitates guidance during assembly.

[0009] Preferably, the first angle formed between the outer edge of the lower liner and the vertical direction is 20° to 30°, which facilitates guidance during assembly.

[0010] Preferably, the second included angle formed by the outer edge of the upper liner and the vertical direction is 5° to 10°, which facilitates guidance during assembly.

[0011] Preferably, the outer surface of the reinforcing block is coated with EN AW-4045 7.5% coating, which facilitates overall brazing.

[0012] Preferably, the back plate is recessed along the longitudinal central axis to form a relief groove, so as to avoid the weld of the heat sink affecting the contact between the back plate and the heat sink.

[0013] Preferably, the back plate has chamfers on both sides for easy assembly.

[0014] An installation structure for a limiting and anti-loosening intercooler reinforcing block is provided, wherein a turbulence plate is installed inside the heat dissipation tube, the reinforcing block is hammered in from the end of the heat dissipation tube along the edge, and the turbulence plate is squeezed until the upper surface of the reinforcing block is flush with the upper surface of the heat dissipation tube, and the boss is hung on the turbulence plate.

[0015] Preferably, the reinforcing block is fitted with the heat dissipation pipe with a clearance.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. To avoid the reinforcing blocks being driven into the heat sink tubes by the sprayed flux during the production process, thus preventing product defects and improving the welding pass rate of the process;

[0018] 2. The boss can also ensure the accuracy and stability of the reinforcement block assembly position. After welding, it enhances the strength of the heat dissipation pipe root, thereby improving product reliability. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a limiting and anti-loosening intercooler reinforcing block includes a back plate 1. The back plate 1 includes an upper part 2, a transition part 3, and a lower part 4. The width of the lower part 4 of the back plate 1 is smaller than the width of the upper part 2. The transition part 3 of the back plate 1 is trapezoidal or has arc-shaped sides. Upper liner plates 5 are symmetrically installed on both sides of the upper part of the back plate 1. The upper edges of the two upper liner plates 5 continue to extend horizontally away from the back plate 1 to form bosses 6. Lower liner plates 7 are symmetrically installed on both sides of the lower part 4 of the back plate 1. A transition plate 8 connecting the upper liner plates 5 and the lower liner plates 7 is installed on the transition part 3 of the back plate 1.

[0028] In this embodiment, the maximum width of the reinforcing block 9 located on the two upper lining plates 5 facing the opening is greater than the width located on the upper part of the back plate 1, which facilitates installation. Figure 3 As shown, the maximum width of the reinforcing block 9 located on the two upper liner plates 5 facing the opening direction is 7.21 mm, and the width of the upper part of the back plate 1 of the reinforcing block 9 is 7.05 mm.

[0029] Furthermore, the width of the reinforcing block 9 at the lower part 4 of the back plate 1 is smaller than the width at the upper part 2 of the back plate 1. In this embodiment, as shown... Figure 2 As shown, the width of the reinforcing block 9 located at position 4 below the back plate 1 is 6.7mm. Figure 1 As shown, the first included angle α formed by the outer edge of the lower liner 7 and the vertical direction is 20° to 30°, and in this embodiment it is 24°. The second included angle b formed by the outer edge of the upper liner 5 and the vertical direction is 5° to 10°, and in this embodiment it is 5°, which facilitates guidance during assembly. Figure 3 As shown, the back plate 1 has chamfers on both sides. In this embodiment, the radius of the chamfers is 0.8mm, which facilitates assembly.

[0030] In this embodiment, as Figure 1 As shown, the dimensions of boss 6 are 2mm in length and 1.5mm in height.

[0031] In this embodiment, the outer surface of the reinforcing block 9 is coated with EN AW-4045 7.5% coating, which facilitates overall brazing.

[0032] Finally, the backplate 1 is recessed along the longitudinal central axis to form a relief groove 10, so as to avoid the weld of the heat sink 11 from affecting the contact between the backplate 1 and the heat sink 11.

[0033] When installing the intercooler reinforcing block that can limit and prevent loosening in this embodiment, such as... Figure 4 and Figure 5 As shown, a turbulence plate 12 is installed inside the heat sink 11. A reinforcing block 9 is hammered into the heat sink 11 from the end along the edge and squeezes the turbulence plate 12 until the upper surface of the reinforcing block 9 is flush with the upper surface of the heat sink 11, and the boss 6 is hung on the turbulence plate 12. The reinforcing block 9 and the heat sink 11 are fitted with a clearance fit.

[0034] This invention provides a limiting and anti-loosening intercooler reinforcing block and its installation structure, which prevents the reinforcing block 9 from being driven into the heat sink 11 by the sprayed welding flux during the production process, thus avoiding product defects and improving the welding qualification rate of the process. The boss 6 can also ensure the accuracy and stability of the assembly position of the reinforcing block 9. After welding, it enhances the strength of the root of the heat sink 11, thereby improving product reliability.
