Description

Technical Field

[0001] This utility model belongs to the field of radiator technology, specifically relating to a spliced ​​water-air cooler. Background Technology

[0002] The intercooler (i.e., air-to-water intercooler) is an indispensable key heat exchange component in modern internal combustion engines (especially turbocharged engines). Its core function is to exchange heat with the surface of the intercooler's heat dissipation core through cooling air, thereby reducing the temperature of the coolant in the internal channels of the heat dissipation core.

[0003] Due to the requirements of vehicle structural design, the location where the intercooler is installed and the surrounding sheet metal parts (such as the inner panel of the engine hood, the longitudinal beams of the frame, or the partitions) often present non-planar or curved contours with a certain angle.

[0004] Existing water-air coolers mostly adopt a monolithic planar design, and this standardized or relatively simple geometric shape has significant limitations:

[0005] 1. Poor space adaptability: When the water-intercooler needs to be installed in a complex part of the vehicle body with a specific angle (especially an obtuse angle), the shape of the existing intercooler is difficult to fit the vehicle body structure, resulting in low space utilization.

[0006] 2. Poor sealing and air leakage: The direct consequence of the above-mentioned mismatch in space is that, under the forced airflow generated by the fan system or vehicle movement, some airflow cannot be effectively guided to the surface of the intercooler's heat dissipation core for heat exchange. Instead, it leaks in the gap between the core surface and the vehicle body sheet metal parts (i.e., the poor fit). This "air leakage" phenomenon greatly reduces the amount of airflow that can effectively pass through the heat dissipation surface.

[0007] 3. Impaired heat dissipation efficiency: The loss of air volume directly leads to a decrease in heat dissipation efficiency. Due to insufficient effective cooling air volume through the core, the heat exchange between the boosted air and the coolant is not sufficient, and the final temperature of the boosted air may be higher than the design target value, affecting the engine's performance output. Utility Model Content

[0008] This invention addresses the aforementioned problems in the existing technology by proposing a modular water-air cooler that can effectively reduce or eliminate airflow leakage to improve heat dissipation.

[0009] This utility model can be achieved through the following technical solutions:

[0010] A modular water-air cooler, comprising:

[0011] The heat dissipation assembly is formed by a first heat dissipation core and a second heat dissipation core fixedly connected together, with an obtuse angle between the first heat dissipation core and the second heat dissipation core;

[0012] The first heat dissipation core has the same structure as the second heat dissipation core and has a plurality of gas channels and liquid channels, wherein the gas channels and the liquid channels are arranged at intervals.

[0013] The water inlet cap and the water outlet cap are respectively disposed on both sides of the heat dissipation assembly. The water inlet cap has a water inlet and the water outlet cap has a water outlet. The two ends of the liquid channel are respectively connected to the inner cavities of the water inlet cap and the water outlet cap.

[0014] As a further improvement of this utility model, the first heat dissipation core and the second heat dissipation core are connected front to back, and the walls of the two adjacent liquid channels are fixedly connected.

[0015] As a further improvement of this utility model, the water inlet seal and the water outlet seal have obtuse-angled curved surfaces that match the heat dissipation assembly.

[0016] As a further improvement of this utility model, the water inlet cap is also provided with a water inlet.

[0017] As a further improvement of this utility model, the water inlet seal is also provided with a sensor mounting port, which is used to install a temperature sensor.

[0018] As a further improvement of this utility model, the inlet is arranged at an angle and is used to connect a water pipe.

[0019] As a further improvement of this utility model, at least one water outlet is provided on the water outlet seal head.

[0020] As a further improvement of this utility model, the water outlet and the water inlet are located on the same side of the water-air cooler.

[0021] As a further improvement of this utility model, both the inlet seal and the outlet seal are provided with mounting and positioning pins, and the two mounting and positioning pins are arranged symmetrically on the left and right.

[0022] As a further improvement of this utility model, the mounting positioning pin is located on the front and rear sides of the water-air cooler, respectively, along with the water inlet and the water outlet.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. Improved space adaptability and sealing performance: By splicing the first heat dissipation core and the second heat dissipation core at an obtuse angle, and using inlet and outlet water seals with matching obtuse angle curved surfaces, the intercooler can better fit the complex structure inside the engine compartment, reduce the gap between it and surrounding components, effectively prevent cooling air leakage, and improve airflow utilization and heat dissipation effect.

[0025] 2. Enhanced heat exchange efficiency and system stability: Gas channels and liquid channels are arranged alternately. The coolant circulates in the liquid channels, while the cooling air flows through the external gas channels. The two achieve efficient heat exchange through the heat dissipation core. At the same time, the walls of adjacent liquid channels are fixedly connected to ensure uniform distribution and stable flow of coolant, thereby improving the overall heat exchange efficiency and operational reliability.

[0026] 3. Optimize coolant management and maintainability: Independent filler and inlet ports are provided, with clear functions and no interference between them, which facilitates the initial filling, subsequent replenishment and bleed operation of coolant and avoids air lock; the inclined arrangement of the inlet port is conducive to smooth flow of coolant, further improving the system circulation efficiency and ease of use;

[0027] 4. Improve assembly precision and installation convenience: The inlet and outlet water seals are equipped with symmetrical mounting and positioning pins, which are located on different surfaces of the intercooler, respectively, to achieve spatial separation of the functional interface and positioning structure. This not only improves assembly precision and vibration resistance, but also simplifies the vehicle assembly and maintenance process.

[0028] 5. Enhance intelligent control capabilities and system synergy: By setting a sensor mounting port on the water inlet head for installing a temperature sensor, real-time monitoring of coolant temperature can be achieved, providing feedback signals to the engine control system. This helps to dynamically adjust parameters such as fan speed and cooling flow, thereby improving the overall vehicle thermal management efficiency and energy utilization level.

[0036] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0037] like Figures 1-3 As shown, this utility model provides a modular water-air cooler, comprising:

[0038] The heat dissipation assembly is formed by a first heat dissipation core 100 and a second heat dissipation core 110 fixedly connected, with an obtuse angle between the first heat dissipation core 100 and the second heat dissipation core 110.

[0039] The first heat dissipation core 100 and the second heat dissipation core 110 have the same structure and have several gas channels 120 and liquid channels 130. The gas channels 120 and liquid channels 130 are arranged at intervals to achieve efficient heat exchange between air and coolant.

[0040] The inlet cap 200 and the outlet cap 300 are respectively located on both sides of the heat dissipation assembly. The inlet cap 200 is provided with an inlet 210, and the outlet cap 300 is provided with an outlet 310. The two ends of the liquid channel 130 are respectively connected to the inner cavities of the inlet cap 200 and the outlet cap 300 to realize the circulation of coolant inside the heat dissipation assembly.

[0041] The cooling principle is as follows: During the operation of the intercooler, cooling air flows through the gas passage on the outside of the heat dissipation assembly, while the coolant circulates in the liquid passage 130 set in the heat dissipation core. The cooling air and coolant exchange heat through the heat dissipation core, which lowers the temperature of the coolant and thus enhances its cooling capacity for high-temperature boosted air. Ultimately, this achieves the goals of increasing intake air density, enhancing engine charging efficiency, optimizing power output, and controlling emissions.

[0042] It is worth mentioning that, in this embodiment, by setting the angle between the first heat dissipation core 100 and the second heat dissipation core 110 to an obtuse angle, the intercooler can better fit the curved or inclined sheet metal structure in the engine compartment, which enhances the overall spatial adaptability of the intercooler to the complex vehicle structure. At the same time, it reduces the gap between the intercooler and the surrounding components, effectively preventing cooling air from leaking from the gap, thereby increasing the effective airflow through the heat dissipation core.

[0043] This obtuse-angle splicing structure significantly improves the problems of poor sealing, low airflow utilization, and poor heat dissipation efficiency of traditional planar intercoolers, thereby improving the working performance and reliability of the intercooler in actual installation environments.

[0044] Preferably, the first heat dissipation core 100 and the second heat dissipation core 110 are joined together, and the walls of the two adjacent liquid channels 130 are fixedly connected (e.g., welded). This ensures that the two heat dissipation cores not only have good mechanical strength and sealing at the joint, but also ensures a smooth transition and uniform distribution of coolant between the two cores.

[0045] By fixing the pipe walls of adjacent liquid channels 130 together, it is possible to effectively avoid coolant leakage or local flow obstruction caused by loose structure or loose connection, thereby improving the overall heat exchange efficiency and operational stability of the intercooler.

[0046] In addition, the front and rear docking and fixed connection structure also helps to simplify the manufacturing process and assembly process, and improve the manufacturability and consistency of the product while ensuring performance.

[0047] Preferably, the inlet end cap 200 and the outlet end cap 300 have obtuse-angled curved surfaces that match the heat dissipation assembly, which can achieve a high degree of compatibility between the overall shape of the intercooler and the complex sheet metal structure in the engine compartment, further improving the utilization rate of the installation space.

[0048] Preferably, the inlet cap 200 is also provided with a water inlet 220 and a sealing cap 221, which are used during the initial installation of the system or when the coolant is replaced. It should be noted that the water inlet 220 and the water inlet 210 each have different functions, specifically:

[0049] Inlet 210: Located on the inlet end cap 200 and connected to the vehicle cooling system pipeline, its main function is to guide the coolant from the external circulation system into the liquid channel 130 inside the intercooler during normal operation, thereby achieving continuous cooling of the high-temperature pressurized air. As the inlet for coolant circulation, the inlet 210 is always connected during system operation and is a key interface for maintaining the heat exchange function of the intercooler.

[0050] Filler neck 220: Primarily used for initial or subsequent coolant filling. Since the cooling system may experience insufficient coolant after initial installation or long-term use, coolant can be injected into the intercooler through filler neck 220 to ensure the liquid passage 130 is fully filled, preventing a decrease in cooling efficiency due to airlock. Filler neck 220 is equipped with a sealing cap 221, which remains closed when not in use to prevent coolant leakage or impurities from entering the system.

[0051] By setting up the water inlet 210 and the water filling port 220 separately and clarifying their functional division, not only is the stable circulation operation of the cooling system guaranteed, but the maintainability and ease of use of the intercooler are also significantly improved. This design effectively solves the problems of difficult liquid injection, poor venting, and complex maintenance that exist in traditional integrated structures, and further enhances the practicality and reliability of water-intercooler in the vehicle thermal management system.

[0052] Preferably, the water inlet end cap 200 is also provided with a sensor mounting port 230, which is used to install a temperature sensor. The temperature sensor can monitor the temperature of the coolant entering the intercooler in real time, and can realize real-time monitoring and data acquisition of coolant temperature, thereby providing accurate thermal management information for the engine control unit.

[0053] This design helps the system dynamically adjust the fan speed, cooling circulation flow, or the operating status of other related components based on the actual coolant temperature, further improving the vehicle's thermal management efficiency and energy utilization.

[0054] Preferably, the inlet 210 is inclined and used to connect water pipes. This inclined structure can better adapt to the space layout inside the engine compartment, facilitate the installation and connection of pipes. In addition, the inclined arrangement also facilitates the smooth flow of coolant at the inlet 210, reduces the eddy currents or air resistance generated at the inlet, thereby improving the uniformity of coolant distribution and circulation efficiency inside the intercooler, and further ensuring the heat exchange performance of the intercooler and the stability of system operation.

[0055] Preferably, at least one outlet 310 is provided on the outlet head 300. When multiple outlets 310 are provided, the discharge efficiency of coolant and the overall thermal management capability of the system can be effectively improved.

[0056] Preferably, the outlet 310 and the inlet 210 are located on the same side of the water-air cooler. This layout is conducive to the centralized arrangement of cooling system pipes on the vehicle, simplifies the external connection structure, and is especially suitable for application scenarios where the engine compartment space is compact and the pipe layout is limited. It can significantly improve assembly efficiency and maintenance convenience.

[0057] Preferably, both the inlet end cap 200 and the outlet end cap 300 are equipped with mounting positioning pins 400, and the two mounting positioning pins 400 are symmetrically arranged on the left and right sides. This can provide a reliable assembly benchmark for the intercooler, ensure that its installation position in the engine compartment is accurate, and avoid problems such as poor sealing and stress concentration caused by offset or tilt, thereby improving the overall assembly quality and reliability.

[0058] Furthermore, the mounting positioning pin 400, the water inlet 210, and the water outlet 310 are located on the front and rear sides of the water-air cooler, respectively. This layout is conducive to realizing the separation of functional areas. On the one hand, it avoids spatial interference between the positioning structure and the pipeline interface. On the other hand, it also helps to simplify the vehicle assembly process and improve the convenience of maintenance and replacement operations.
