Abstract
Description
Technical Field
[0001] This utility model relates to the field of intercooler technology, specifically to a cooling module assembly with a spiral water pipe. Background Technology
[0002] Intercoolers are typically installed in turbocharged engines. Turbocharging leads to increased intake air temperature, affecting the engine's charging efficiency. Intercoolers cool the pressurized air, lowering its temperature and thus improving engine power output and fuel economy. Specifically, intercoolers lower the intake air temperature, increasing intake air density and consequently the amount of air entering the cylinders, improving fuel combustion efficiency and thus increasing engine power output. Furthermore, intercoolers also reduce fuel consumption, decrease knocking and nitrogen oxide emissions, and improve the engine's environmental adaptability.
[0003] The pressurized air entering the intercooler contains moisture. In humid regions, the moisture content is higher, causing it to adhere to the intercooler walls and drip down to the bottom of the chamber. A drain valve is installed at the bottom of the chamber to drain this moisture. However, in winter or low-temperature environments, when the vehicle is stationary, idling, or at low speeds, the moisture in the chamber will freeze. Therefore, opening the drain valve will not allow the moisture to drain completely. The frozen moisture will then expand and damage the cooling pipes, causing intercooler leaks and shortening the lifespan of the cooling module. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing a cooling module assembly with a spiral water pipe.
[0005] This utility model is achieved through the following technical solution: a cooling module assembly with a spiral water pipe is provided, including a radiator and an intercooler. The intercooler includes an intercooler core and two air chambers. At least one air chamber is provided with a heating pipe. The heating pipe passes through the air chamber at both ends and is respectively connected to the inlet and outlet of the radiator.
[0006] As an optimization, the heating tubes are arranged in a spiral or serpentine pattern within the gas chamber.
[0007] As an optimization, the air chamber is arranged vertically, and the heating tube is located at the bottom of the air chamber.
[0008] As an optimization, the heating tube is disposed in the air chamber on the air outlet side.
[0009] As an optimization, a drain valve is installed at the lower end of the air chamber.
[0010] As an optimization, an electrically controlled valve is installed on the pipeline between the heating tube and the radiator inlet, and a temperature sensor is installed on the heating tube.
[0011] As an optimization, both ends of the heating tube extend out of the gas chamber from the side of the gas chamber away from the intercooler core.
[0012] The beneficial effects of this utility model are as follows: The cooling module assembly with a spiral water pipe of this utility model allows high-temperature antifreeze to flow out from the radiator and enter the air chamber through the spiral heating pipe inlet. The hot antifreeze releases heat when it encounters the cold, thus raising the temperature inside the air chamber and solving the freezing problem. When the water in the air chamber freezes and encounters the high-temperature antifreeze, the frozen water defreezes and is discharged through the drain valve, ensuring the safety of the engine.

[0022] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0023] like Figures 1-7 As shown, the present invention discloses a cooling module assembly with a spiral water pipe, including a radiator and an intercooler. The intercooler includes an intercooler core 2 and two air chambers 1, which are respectively connected to the two ends of the intercooler core 2. The high-temperature air from the turbocharger enters from the air chamber 1 on the intake side, is cooled by the intercooler core 2, and is discharged from the air chamber 1 on the exhaust side, thereby cooling the air. In order to prevent the condensate from freezing in the low-temperature environment, at least one air chamber 1 is provided with a heating pipe 3. In this embodiment, the heating pipe 3 is located in the air chamber 1 on the exhaust side.
[0024] During installation, the air chamber 1 is set vertically to facilitate the flow of condensate to the lower end. In this embodiment, a drain valve is installed at the lower end of the air chamber 1 to periodically drain the condensate.
[0025] Since the bottom of the air chamber 1 is prone to icing, the heating tube 3 is placed at the bottom of the air chamber 1. The height of the icing-prone area is H, and the height of the heating tube 3 is H1, where H1 ≤ H.
[0026] To achieve the desired heating effect, the heating tube 3 is sealed at both ends, exiting the air chamber 1 from the side away from the intercooler core 2. Furthermore, both ends of the heating tube 3 are connected to the inlet and outlet of the radiator, respectively. Figure 6 As shown, the inlet end of the heating tube 3 is connected to the inlet of the radiator via a T-junction, and an electric control valve 7 is installed on the pipeline between the heating tube 3 and the radiator inlet. After the electric control valve 7 is opened, the high-temperature antifreeze that enters the radiator enters the heating tube 3 through the pipeline.
[0027] The outlet of the heating pipe 3 is connected to the outlet of the radiator via a T-junction. Therefore, some of the high-temperature antifreeze entering the radiator enters the heating pipe 3 and then returns to the engine.
[0028] To improve the heating effect, the heating tubes 3 are arranged in a spiral or serpentine shape in the air chamber 1, and the axis of the spiral is parallel to the vertical length direction of the air chamber 1.
[0029] The heating tube 3 is equipped with a temperature sensor 8 for detecting temperature. In this embodiment, the temperature sensor 8 is located on the outside of the heating tube 3 inside the air chamber 1.
[0030] How to use this utility model:
[0031] After the high-temperature antifreeze in the engine flows out, it enters the radiator for cooling. A temperature sensor 8 is installed in the intercooler chamber 1, allowing the user to set a target temperature. When the internal temperature is lower than the set temperature (generally 0°C), the ECU controls the electronic control valve 7 to open, allowing the high-temperature antifreeze in the engine to enter the heating pipe 3 through the three-way valve. This raises the temperature inside the intercooler chamber 2, causing ice to melt, and water can be drained through the drain valve 5 at the bottom of the intercooler chamber 2. The cooled antifreeze in the heating pipe 3 and the antifreeze flowing from the radiator converge through the three-way valve and then enter the engine.
[0032] When the temperature detected by temperature sensor 8 reaches the set temperature, the electric control valve 7 closes.
[0033] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here.
