Description

Technical Field

[0001] This utility model relates to the field of intercooler technology, and in particular to an intercooler for heavy-duty trucks. Background Technology

[0002] Intercoolers are one of the most important components of turbocharged engines. Traditional all-aluminum alloy intercoolers are not only heavy, but also have high welding costs and metal material costs. Therefore, intercoolers with plastic chambers have become the mainstream trend.

[0003] With technological advancements, the original all-aluminum welded structure of the intercooler has been gradually upgraded to a plastic press-fit structure. However, in actual use, because the medium passing through the intercooler is high-temperature, high-pressure gas, the plastic intercooler is prone to deformation under the action of this gas. This can cause the pressure-locked intercooler to detach from the mainboard, resulting in leakage. To address this issue, we propose a heavy-duty truck intercooler. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a heavy-duty truck intercooler that solves the issue of insufficient strength in the press-fit connection between the plastic air chamber and the mainboard, thereby reducing deformation and failure.

[0005] The technical solution of this utility model is:

[0006] A heavy-duty truck intercooler includes: an aluminum core body, which is composed of air pipes and fins;

[0007] There are two plastic air chambers, one at each end of the aluminum core;

[0008] There are two aluminum mainboards, one on each side of the plastic air chamber;

[0009] There are two galvanized sheets, one on each side of the aluminum main board;

[0010] There are two baffles, one at the top and one at the bottom of the aluminum core.

[0011] In a further technical solution, the plastic air chamber is made of high-temperature resistant, high-strength plastic, with mounting holes at both the top and bottom ends. The side connected to the aluminum main board is provided with a raised pressing edge and a horizontal parallel rib, which is pressed and snapped into the aluminum main plate.

[0012] In a further technical solution, the edge of the aluminum main board is provided with first uniform buckles of equal height. The buckles are bent inward and abut against the parallel ribs of the plastic air chamber. The aluminum main board is provided with a groove, and a rubber sealing ring is installed in the groove.

[0013] In a further technical solution, the galvanized plate is provided with a second uniform buckle tooth, which engages with the parallel ribs of the plastic air chamber.

[0014] In a further technical solution, the outer sides of both ends of the motherboard are provided with third latching teeth, and the baffle is engaged with the third latching teeth at the upper and lower ends of the motherboard.

[0015] In a further technical solution, the aluminum core is composed of air pipes and fins, and is connected to the aluminum main board by brazing.

[0016] The beneficial effects of this utility model are:

[0017] Compared to aluminum air chambers, this invention uses plastic air chambers, which greatly reduces the weight of the heavy-duty truck intercooler. Furthermore, the snap-fit ​​connection with the main board significantly reduces the complexity and cost of welding processes. Additionally, the use of galvanized plates further strengthens the snap-fit ​​connection between the main board and the plastic air chamber, making the intercooler more robust and reliable overall, and further enhancing its stability and reliability.

[0025] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0026] Example:

[0027] A heavy-duty truck intercooler, such as Figure 1 As shown, it includes a plastic air chamber 1, a rubber sealing ring 2, an aluminum main board 3, a galvanized sheet 4, a baffle 6, and an aluminum core composed of an air pipe 5 and fins (not shown).

[0028] In another embodiment, the plastic air chamber 1 is made of high-temperature resistant, high-strength plastic, with mounting holes at both the top and bottom. The side connecting to the aluminum main plate 3 has a raised pressing edge and horizontal parallel ribs for pressing and engaging with the main plate 3. Figure 4 .

[0029] In another embodiment, the edge of the aluminum main board 3 is provided with uniformly high buckling teeth, which are bent inward and abut against the parallel ribs of the air chamber. This snapping method is convenient and quick compared to the welding method of the aluminum air chamber. The aluminum main board 3 is provided with a groove to install a rubber sealing ring, which is pressed between the main board and the air chamber during pressing.

[0030] In another embodiment, the aluminum mainboard 3 has two galvanized plates 4 on its outer sides. The galvanized plates 4 and the aluminum mainboard 3 have the same uniform serrations, such as... Figure 3 While the aluminum main board 3 is pressed and snapped into the air chamber, the galvanized plate 4 is also pressed together with the main board 3 and the plastic air chamber 1 to strengthen the snapping between the main board 3 and the plastic air chamber 1.

[0031] In another embodiment, the upper and lower baffles 6 are engaged with the outer teeth at the upper and lower ends of the main board 3, such as... Figure 4 .

[0032] In another embodiment, the aluminum core consists of an air pipe 5 and fins, which are connected to the aluminum mainboard 3 by brazing.

[0033] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
