Description

Technical Field

[0001] The invention relates to the technical field of intercoolers, in particular to an aluminum-plastic brazed tube-fin type water-to-air intercooler structure. Background Art

[0002] Intercoolers are often considered a type of radiator, used to cool the high-temperature air compressed by the engine turbocharger. After the compressed air is compressed and heated by the supercharger, it is input into the intercooler through the intake pipe. After sufficient heat exchange and cooling by the intercooler, it enters the engine combustion chamber through the outlet pipe, which can effectively improve the engine efficiency and performance. According to the different cooling media, commonly used intercoolers can be divided into air-cooled and water-cooled forms. Air-cooled intercoolers are air intercoolers that often form front-end cooling modules with fans, radiators, condensers, etc., while water-cooled intercoolers are similar to conventional radiators, and the compressed air is cooled by flowing coolant through the surface.

[0003] However, there are certain problems in the use of air-cooled intercoolers or water-cooled intercoolers. Air-cooled intercoolers are mainly cooled by fans and ambient ventilation, but high-temperature air needs to pass through pipes from the supercharger to the front of the car, and then pass through pipes to the throttle after cooling, which will aggravate turbo lag. Compared with air-cooled intercoolers, water-cooled intercoolers have a relatively compact structure and are easy to arrange. They can effectively shorten the stroke of the inlet and outlet pipes connecting the engine. At the same time, the coolant circulation volume flowing through the water-cooled intercooler is relatively stable, which can significantly reduce turbo lag. However, the current water-cooled intercooler has a relatively complex structure and the circulating coolant has the risk of leakage.

[0004] Therefore, considering the overall engine compartment layout, the size of the air-cooled intercooler is limited, and a dedicated position needs to be reserved at the front of the vehicle. At this stage, the overall number of vehicles in my country has increased significantly, and the probability of low-speed driving in urban areas is higher. The advantages of traditional air-cooled intercoolers cannot be fully utilized. How to effectively optimize the intercooler structure and improve manufacturability and assemblability has become the key. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an aluminum-plastic brazed tube-fin water-to-air intercooler structure, which has the advantages of effectively reducing the volume, optimizing the overall assembly structure, and reducing the risk of coolant leakage. It solves the problems of optimizing the intercooler structure and improving manufacturability and assemblability.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An aluminum-plastic brazed tube-fin water-to-air intercooler structure comprises a heat dissipation tube assembly and a cooling assembly; the heat dissipation tube assembly comprises a plurality of heat dissipation tube sleeves distributed in an array, each heat dissipation tube sleeve is provided with a heat dissipation coil inside, and the two ends of the heat dissipation tube sleeve are respectively connected to the hole grooves corresponding to the first main plate and the second main plate; the cooling assembly comprises a heat dissipation belt, a water inlet pipe, a water outlet pipe, and two cavities, the two ends of the heat dissipation belt are arranged between the first shell and the second shell, the upper and lower surfaces of the heat dissipation belt are located between the corresponding heat dissipation coils, the heat dissipation belt placed inside can conduct heat to the air inside the heat dissipation coil, the two cavities are opened on the side wall of the first shell and are separately arranged on the left and right sides thereof, and the heat dissipation belt adopts a corrugated shape with front row peaks and rear row peaks staggered.

[0010] Furthermore, the heat dissipation pipe assembly includes a heat dissipation coil and a heat dissipation pipe sleeve, and the heat dissipation coil and the heat dissipation pipe sleeve are both arranged between the upper guard plate and the lower guard plate.

[0011] Furthermore, the heat dissipation coil is located in the heat dissipation pipe sleeve.

[0012] Furthermore, the cooling assembly includes a heat dissipation belt, a water inlet pipe, a water outlet pipe and two cavities. The heat dissipation belt is arranged between the first shell and the second shell. The two cavities are opened on the side wall of the first shell and are separated on the left and right sides thereof.

[0013] Furthermore, the first air chamber, the second air chamber, the upper guard plate, the lower guard plate, the first shell and the second shell form a cavity therein, and the back sides of the two cavities are connected to the cavity.

The water inlet pipe and the water outlet pipe are used to transport the flowing coolant, and the coolant flowing into the cavity enters the interior of the cavity and contacts the heat dissipation belt, thereby exchanging heat with the heat dissipation belt.

The front and rear peaks are staggered to form multiple channels. This design expands the contact area with the air and can speed up the cooling speed more efficiently.
