Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, specifically to a lightweight intercooler based on aluminothermic composite material. Background Technology

[0002] With the rapid development of new energy vehicles, aerospace and other fields, the power system has placed higher demands on the performance of the intercooler.

[0003] Existing intercoolers are mostly designed with flat heat dissipation fins and a single flow channel, which makes it difficult to effectively enhance airflow turbulence, resulting in high boundary layer thermal resistance and difficulty in improving heat exchange efficiency. At the same time, in order to ensure structural strength, it is often necessary to increase the material thickness, which further increases the weight. In addition, the flow field distribution of traditional intercoolers is uneven, which easily forms local high temperature zones, which not only reduces heat dissipation efficiency, but also affects the stability and service life of the equipment.

[0008] Preferably, the outer wall of the corrugated pipe is fixedly connected to the outer wall of the intercooler body, and the outer wall of the corrugated pipe is arranged in a linear array along the outer wall of the intercooler body. The wavy path of the corrugated plate changes the airflow direction, extends the heat exchange path and enhances the boundary layer disturbance, thereby improving the heat exchange efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] Please see Figure 1-3This utility model provides a technical solution: a lightweight intercooler based on aluminothermic composite material, comprising:

[0023] Intercooler body 1, with a lightweight device 2 fixedly connected to the outer wall of the intercooler body 1. The lightweight device 2 dissipates heat by changing the path. An auxiliary device 3 is provided on the inner wall of the intercooler body 1. The intercooler body 1 can reduce its weight by using the lightweight device 2 and accelerate the airflow. The auxiliary device 3 further accelerates the airflow.

[0024] The lightweight device 2 includes a corrugated plate 20. The inner wall of the corrugated plate 20 has weight-reducing holes 21, and the inner wall of the weight-reducing holes 21 is arranged in a linear array along the inner wall of the corrugated pipe. The outer wall of the corrugated pipe is fixedly connected to the outer wall of the intercooler body 1, and the outer wall of the corrugated pipe is arranged in a linear array along the outer wall of the intercooler body 1. The lightweight device 2, which conducts heat to the outer wall of the intercooler body 1, is affected by the wave shape of the corrugated plate 20, which forces the airflow to constantly change direction, lengthens the heat exchange path, enhances boundary layer disturbance, and improves heat exchange efficiency. The weight-reducing holes 21 arranged in a linear array on the corrugated plate 20 reduce weight, and the opening edges of the holes cause the air to form micro vortices, further enhancing turbulence and accelerating the speed at which heat is transferred from the airflow to the surface of the corrugated plate 20.

[0025] The auxiliary device 3 includes a trapezoidal hole 30. The end of the trapezoidal hole 30 with a larger diameter is the air inlet end, and the end with a smaller diameter is the air outlet end. When working, air enters the trapezoidal hole 30. The Venturi effect formed by the gradual narrowing of the hole diameter accelerates the airflow and reduces the flow resistance, optimizes the flow field distribution, and avoids local high temperature accumulation.

[0026] The auxiliary device 3 also includes a honeycomb plate 31. The outer wall of the honeycomb plate 31 is fixedly connected to the inner wall of the intercooler body 1. After the high-temperature pressurized air enters the intercooler body 1, it first contacts the honeycomb plate 31 on the inner wall. With its hexagonal structure, the honeycomb plate 31 provides stable support while reducing weight and enhancing the overall rigidity of the intercooler.

[0027] When in use, the intercooler body 1 reduces weight through the lightweight device 2 while accelerating airflow, and the auxiliary device 3 further accelerates airflow.

[0028] First, during operation, the high-temperature pressurized air enters the intercooler body 1 and comes into contact with the honeycomb plate 31 on the inner wall. The honeycomb plate 31, with its hexagonal structure, provides stable support while reducing weight and enhancing the overall rigidity of the intercooler. Then, the air enters the trapezoidal hole 30 and uses the Venturi effect formed by the gradual narrowing of the hole to accelerate the airflow and reduce the flow resistance, optimize the flow field distribution, and avoid local high temperature accumulation.

[0029] The lightweight device 2 that conducts heat to the outer wall of the intercooler body 1, the corrugated plate 20’s wave shape forces the airflow to constantly change direction, lengthens the heat exchange path, enhances boundary layer disturbance, and improves heat exchange efficiency. Meanwhile, the weight-reducing holes 21 arranged in a linear array on the corrugated plate 20 reduce weight, and the opening edges of the holes cause the air to form micro vortices, further enhancing turbulence and accelerating the speed at which heat is transferred from the airflow to the surface of the corrugated plate 20.

[0030] By utilizing the properties of the intercooler body 1 material, optimizing airflow with the inner wall auxiliary device 3, and enhancing heat exchange with the outer wall lightweight device 2, this intercooler achieves a synergy between lightweight design and efficient heat dissipation, effectively reducing engine load and fuel consumption.
