Description

Technical Field

[0001] This utility model belongs to the field of radiator technology, specifically relating to a water-air cooler that improves heat dissipation. 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 between the cooling air and the surface of the intercooler's heat dissipation core to reduce the temperature of the coolant in the internal channels of the heat dissipation core.

[0003] However, in existing technologies, the gas passage section of such water-to-air intercoolers often employs an open-fin structure similar to that of traditional air-cooled intercoolers, meaning their heat dissipation efficiency largely depends on the randomness of external airflow or simple fan ventilation. This design primarily suffers from the following bottlenecks:

[0004] 1. Disordered and insufficient airflow organization: The external airflow (whether it is ambient wind or direct fan blowing) lacks an effective guiding and converging mechanism, resulting in extremely uneven distribution of airflow on the outer surface of the gas channel, with obvious heat dissipation "blind spots" or low flow rate areas.

[0005] 2. Low cooling air utilization: A large amount of cooling air escapes without making sufficient contact with the heat dissipation surface, failing to effectively remove heat.

[0006] 3. Unstable heat dissipation performance: The heat dissipation effect is highly dependent on external factors such as ambient airflow conditions and fan operating status, making it difficult to ensure that the gas channel is always in a state of efficient and uniform forced convection heat dissipation. Utility Model Content

[0007] This invention addresses the aforementioned problems in the existing technology by proposing a water-air cooler that improves heat dissipation.

[0008] This utility model can be achieved through the following technical solutions:

[0009] A water-to-air cooler for improving heat dissipation includes:

[0010] The heat dissipation core has several spaced-apart gas channels and liquid channels.

[0011] The water inlet cap and the water outlet cap are respectively disposed on both sides of the heat dissipation core. 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 water inlet and the water outlet.

[0012] A fan shroud is connected to the end face of the heat dissipation core. The fan shroud surrounds and forms an air guide channel, and each of the gas channels is connected to the air guide channel.

[0013] As a further improvement of this utility model, at least one heat dissipation core is provided. When there are multiple heat dissipation cores, they are stacked one on top of the other to form a heat dissipation assembly.

[0014] As a further improvement of this utility model, in the heat dissipation assembly, the gas channels of each of the heat dissipation cores are interconnected.

[0015] As a further improvement of this utility model, one side of the wind cover is bent inward to form an installation mating surface.

[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 water inlet, the water outlet, and the sensor mounting port are distributed on the same surface of the water inlet head.

[0019] As a further improvement of this utility model, at least one water outlet is provided. When there are multiple outlets, the inner cavity of the water outlet head is divided into multiple water outlet cavities by a partition, and the water outlet cavities are arranged one-to-one with the water outlets.

[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.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Improve heat dissipation efficiency and optimize airflow organization: By setting up a fan shroud to form an air guide channel and connecting it with the gas channel, the cooling air is effectively concentrated and guided, which improves the problem of uneven airflow distribution and heat dissipation blind spots in traditional structures and significantly improves heat exchange efficiency;

[0024] 2. Modular stacked structure enhances adaptability and scalability: Multiple heat dissipation cores are stacked one on top of the other and connected to the gas channels, which not only increases the heat exchange area per unit volume, but also extends the contact time between the cooling air and the wall, enhancing the cooling effect. It also has good spatial adaptability and modular expansion capabilities.

[0025] 3. Integrated structural design improves assembly accuracy and maintenance convenience: The water inlet, outlet, water filling port and sensor mounting port are centrally arranged on the same side. With the design of positioning pins and mounting mating surfaces, the whole vehicle piping and installation process is simplified, the assembly accuracy is improved, and it is convenient for later maintenance and replacement.

[0026] 4. Coolant zone control to improve system stability: The water outlet head is equipped with a baffle to divide the water outlet chamber into multiple independent chambers, realizing independent control of multiple water outlets, preventing coolant cross-flow, and improving flow uniformity and system operation stability.

[0035] 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.

[0036] like Figures 1-3 As shown, this utility model provides a water-to-air cooler for improving heat dissipation, comprising:

[0037] The heat dissipation core 100 has a number of spaced gas channels 110 and liquid channels 120.

[0038] The water inlet end cap 200 and the water outlet end cap 300 are respectively disposed on both sides of the heat dissipation core 100. The water inlet end cap 200 has a water inlet 210 and the water outlet end cap 300 has a water outlet 310. The two ends of the liquid channel 120 are respectively connected to the water inlet 210 and the water outlet 310.

[0039] The fan cover 400 is connected to the end face of the heat dissipation core 100. The fan cover 400 forms a semi-enclosed air guide channel, and each gas channel 110 is connected to the air guide channel.

[0040] The cooling principle is as follows: During the operation of the water-air cooler, the cooling air flows through the gas channel 110 on the outside of the heat dissipation core 100, while the coolant circulates in the liquid channel 120 set inside the heat dissipation core 100. The cooling air and the coolant exchange heat through the heat dissipation core 100, which lowers the temperature of the coolant and thus enhances its cooling capacity for high-temperature pressurized air. Ultimately, this achieves the goals of increasing intake air density, enhancing engine charging efficiency, optimizing power output, and improving emission control.

[0041] It should be noted that current water-to-air air coolers have the following problems:

[0042] 1. Disordered and insufficient airflow organization: Traditional designs lack effective airflow guiding structures, resulting in uneven distribution of cooling air and obvious low flow velocity areas or heat dissipation blind spots.

[0043] 2. Low cooling air utilization: A large amount of cooling air is exhausted before it fully contacts the heat dissipation surface, resulting in waste of resources and affecting heat dissipation efficiency;

[0044] 3. Unstable heat dissipation performance: It depends on the external airflow conditions or the working status of the fan, making it difficult to guarantee a continuous and efficient heat dissipation effect.

[0045] To address the aforementioned issues, this embodiment incorporates a wind shield 400 structure. The wind shield 400 serves the following functions:

[0046] 1. Centralized guidance of cooling airflow: The fan cover 400 can effectively gather the cooling air entering from the outside and guide it into each gas channel 110, avoiding airflow loss or uneven distribution;

[0047] 2. Optimize airflow organization: By designing the air guide channel, the uniformity of cooling air flow on the surface of the gas channel 110 is enhanced, reducing heat dissipation "blind spots" and improving overall heat exchange efficiency;

[0048] 3. Enhanced forced convection effect: When the fan shroud 400 is used in conjunction with a fan, it can significantly increase the flow rate and coverage area of ​​the cooling air, ensuring that the gas passage 110 is always in a state of efficient convection.

[0049] Overall, by introducing the shroud 400 and optimizing the layout of the gas passage 110 and the liquid passage 120, the key problems of the existing water-air intercooler, such as unreasonable airflow organization, low cooling efficiency, and large fluctuations in heat dissipation performance, have been effectively solved. The improved water-air intercooler not only improves cooling efficiency and system stability, but also enhances the equipment's adaptability under complex operating conditions, providing more reliable cooling protection for high-performance engines.

[0050] Preferably, at least one heat dissipation core 100 is provided as the basic heat dissipation unit of the water-air cooler. When it is necessary to enhance the overall heat dissipation capacity, multiple heat dissipation cores 100 can be stacked vertically to form an integrated heat dissipation assembly. This heat dissipation assembly has good scalability and modularity in structure.

[0051] More importantly, in this heat dissipation assembly, the gas channels 110 between each heat dissipation core 100 are interconnected, so that the cooling air can achieve uniform flow and distribution throughout the entire heat dissipation assembly, without airflow blockage or local stagnation caused by the isolation between modules. At the same time, the structure formed by stacking multiple heat dissipation cores 100 increases the flow path of the cooling air, thereby effectively extending the heat exchange time between the cooling air and the wall of the heat dissipation core 100.

[0052] This structural design balances space utilization, optimized airflow organization, and sufficient heat exchange, providing a more efficient, stable, and adaptable cooling solution for high-performance engines.

[0053] Preferably, one side of the shroud 400 is bent inward to form a mounting mating surface 410. The design of the mounting mating surface 410 allows the shroud 400 to be precisely positioned and nested with the external structure through this folded edge. This structure helps to reduce the overall space occupied by the intercooler, making the equipment easier to embed in complex spatial environments and improving the space utilization of the whole vehicle or the whole machine.

[0054] In addition, the mounting mating surface 410 provides reliable mechanical support and limiting reference, avoiding problems such as misalignment and loosening when the wind cover 400 is connected to the external structure. In vibration or impact environments (such as during vehicle operation), this structure can effectively prevent the wind cover 400 from falling off or deforming, improving the structural strength and assembly reliability of the system.

[0055] Preferably, the water inlet cap 200 also has a water inlet 220 with a sealing cap (not shown in the figure), which is 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:

[0056] 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 120 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.

[0057] 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 120 is fully filled, preventing a decrease in cooling efficiency due to airlock. Filler neck 220 is equipped with a sealing cap, which remains closed when not in use to prevent coolant leakage or impurities from entering the system.

[0058] 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.

[0059] 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.

[0060] Preferably, the water inlet 210, water outlet 310, and sensor mounting port 230 are distributed on the same surface of the water inlet end cap 200, and the water outlet 310 and the water inlet 210 are located on the same surface 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.

[0061] Preferably, at least one outlet 310 is provided as the basic channel for coolant outflow. When it is necessary to improve the flow distribution capacity of the cooling system or meet the needs of multiple cooling sources, multiple outlets 310 can be provided.

[0062] To achieve independent control between each outlet 310 and prevent coolant mixing and backflow at the outlet end, a baffle 320 structure can be installed in the inner cavity of the outlet head 300. This baffle 320 divides the inner cavity of the outlet head 300 into multiple isolated outlet chambers, each corresponding to one outlet 310, thereby achieving zoned control and efficient discharge of coolant.

[0063] Preferably, both the inlet end cap 200 and the outlet end cap 300 are equipped with mounting positioning pins 500, which can provide a reliable assembly reference 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.
