Technical Field
[0001] This utility model relates to the field of engine cylinder head technology, specifically to an engine cylinder head with high-efficiency heat dissipation. Background Technology
[0002] Traditional engine cylinder heads are mostly made of cast iron or cast aluminum. Their heat dissipation efficiency is limited by the material's thermal conductivity and structural design, easily leading to heat accumulation in high-temperature areas and causing problems such as thermal deformation, cracking, and seal failure. Especially under high-load conditions, excessively high local temperatures in the cylinder head can accelerate component wear, reducing engine reliability and lifespan. Existing cooling solutions mostly rely on external cooling systems or thickened walls, but these have drawbacks such as slow response and bulky structures. With the increasing demands for power density and energy conservation and emission reduction, there is an urgent need for a new cylinder head structure that combines lightweight design with efficient heat conduction. By optimizing the heat transfer path and strengthening the design of the cooling unit, rapid temperature equalization and efficient waste heat dissipation can be achieved, thereby improving the overall performance and durability of the engine.

The beneficial effects of this invention are: by introducing coolant into the engine cylinder head on top of the existing circulating heat dissipation, the circulating heat dissipation of the engine cylinder head is accelerated; by installing heat dissipation blocks and heat dissipation fins on both ends of the engine cylinder head, heat conduction and heat dissipation of the engine cylinder head are improved, thus enhancing the heat dissipation performance of the engine cylinder head.
[0004] Although the device in the aforementioned literature can dissipate heat and cool down, its structure is relatively simple, and the heat sink is not easy to disassemble and assemble, making it difficult to clean when dust accumulates, and the heat dissipation effect is still insufficient.

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. This utility model provides an engine cylinder head with high-efficiency heat dissipation. The device is equipped with a heat-conducting device, which dissipates heat through heat-conducting blocks and heat sinks. A snap-fit component facilitates the easy installation and removal of the heat-conducting component. The heat-conducting block quickly conducts heat generated by the engine cylinder head to the heat sinks. The heat sinks, by increasing the heat dissipation area, dissipate heat into the environment through air convection and radiation, thereby significantly improving heat dissipation efficiency. The snap-fit component makes the installation and removal of the heat-conducting component convenient. Workers can easily remove the heat-conducting component for cleaning, removing accumulated dust and dirt, maintaining heat dissipation performance.

[0019] 2. This utility model provides a high-efficiency heat dissipation engine cylinder head. The device is equipped with a heat exchanger, which significantly improves the heat dissipation capacity and temperature uniformity of the cylinder head exhaust port through efficient latent heat absorption and controllable phase change characteristics. The ease of disassembly and assembly further enhances the system's maintenance flexibility, economy, and adaptability to various scenarios. Paraffin-based PCM absorbs / releases a large amount of latent heat during the phase change process, effectively suppressing the instantaneous high temperature of the exhaust port and avoiding thermal damage caused by localized overheating. Through the "thermal buffering" effect of the phase change material, the rate of temperature change in the cylinder head is slowed, reducing fatigue damage to metal components caused by thermal stress, extending the service life of the cylinder head and surrounding components, suppressing heat radiation from the exhaust port to the surrounding area, reducing passive heating of other parts of the cylinder head, and maintaining overall temperature field balance. After placing the placement box into the corresponding base, the placement box can be secured by inserting the first bolt into the fixing foot. The box is securely fixed, and its interior is designed for storing paraffin-based phase change materials. When the engine cylinder head temperature rises, the phase change material in the heat dissipation layer absorbs heat and undergoes a phase change, transforming from a solid to a liquid state. This absorbs a large amount of heat without significantly increasing the temperature, effectively slowing down the rate of temperature rise in the engine cylinder head. When the engine cylinder head temperature decreases or enters the cooling phase, the phase change material releases heat and undergoes a reverse phase change, transforming from a liquid to a solid state. This releases the previously absorbed heat into the environment, accelerating the cooling process of the engine cylinder head. The temperature of the device is monitored in real time by a temperature sensor. Additionally, the upper end of the box has slots that correspond one-to-one with the inserts at the bottom of the cover, facilitating the closing of the cover. Inserting or removing the second bolt allows for quick opening and closing of the cover. The cover has appropriately sized vents to facilitate venting while preventing material spillage.

Both ends of the engine cylinder head 1 are fixedly connected to heat-conducting devices 2. These devices dissipate heat through heat-conducting blocks and heat sinks. A snap-fit component facilitates easy installation and removal of the heat-conducting components. The heat-conducting blocks quickly transfer heat generated by the engine cylinder head to the heat sinks. The heat sinks, by increasing the heat dissipation area, dissipate heat into the environment through air convection and radiation, significantly improving heat dissipation efficiency. The snap-fit component makes the installation and removal of the heat-conducting components convenient, allowing workers to easily remove and clean them, removing accumulated dust and dirt to maintain heat dissipation performance.

A liquid guide tube 3 is fixedly connected to one side of the heat-conducting device 2. An exhaust pipe 4 is fixedly connected to the upper end of the engine cylinder head 1, and a heat exchange device 5 is fixedly connected to one side of the exhaust pipe 4. This device can significantly improve the heat dissipation capacity and temperature uniformity of the cylinder head exhaust port through efficient latent heat absorption and controllable phase change characteristics. The ease of disassembly and assembly further enhances the system's maintenance flexibility, economy, and scenario adaptability. Paraffin-based PCM can absorb / release a large amount of latent heat during the phase change process, effectively suppressing the instantaneous high temperature of the exhaust port and avoiding thermal damage caused by local overheating. Through the "thermal buffering" effect of the phase change material, the cylinder head temperature change rate is slowed down, reducing the fatigue damage of thermal stress to metal parts, extending the service life of the cylinder head and surrounding components, suppressing the heat radiation from the exhaust port to the surrounding area, reducing the passive heating of other parts of the cylinder head, and maintaining the overall temperature field balance.
[0028] The heat conduction device 2 includes a heat conduction block 21, which is fixedly connected to both ends of the engine cylinder head 1;
[0029] The heat exchange device 5 includes a base 51, the lower end of which is fixedly connected to the upper end of the engine cylinder head 1.
[0030] The bottom of both ends of the engine cylinder head 1 is fixedly connected to a bracket, and a cooling fan is fixedly connected to one end of the bracket.
[0031] like Figure 2 and Figure 3 As shown, a sliding groove 22 is provided on one side of the heat-conducting block 21, a first slot 23 is provided on one side of the sliding groove 22, a retaining plate 24 is movably connected to the inner wall of the sliding groove 22, spring clips 25 are fixedly connected to the bottom of both sides of the retaining plate 24, a second slot 26 is provided on one side of the retaining plate 24, and a heat sink 27 is movably connected to the inner wall of the second slot 26. The sliding groove 22 facilitates the sliding of the retaining plate 24, and the spring clips 25 are provided on both sides of the retaining plate 24.

The second slot 26 on one side of the retaining plate 24 facilitates the quick installation of the heat sink 27, and multiple second slots 26 are provided so that the heat sink 27 can be adjusted at different intervals to achieve different heat dissipation effects.
[0032] like Figure 4 As shown, a placement box 52 is movably connected to the upper end of the base 51. A fixing foot 53 is fixedly connected to the side wall of the placement box 52.

The placement box 52 has a storage space inside to facilitate the placement of paraffin-based phase change material 56. When the temperature of the engine cylinder head 1 rises... When the temperature is high, the phase change material in the heat dissipation layer begins to absorb heat and undergo a phase change, changing from solid to liquid. It absorbs a large amount of heat without significantly increasing the temperature, thus effectively slowing down the temperature rise rate of the engine cylinder head 1. When the temperature of the engine cylinder head 1 decreases or enters the cooling stage, the phase change material begins to release heat and undergoes a reverse phase change, changing from liquid to solid. It releases the previously absorbed heat into the environment, accelerating the cooling process of the engine cylinder head 1. The temperature of the equipment is monitored in real time by a temperature sensor. In addition, a slot 55 is provided at the upper end of the placement box 52, which can correspond one-to-one with the insert block 58 provided at the bottom of the cover plate 57, making it easy to close the cover plate 57.

The cover plate 57 is provided with appropriately sized air holes, which facilitates exhaust while preventing material overflow.
[0033] The working principle of this utility model is as follows: A sliding groove 22 is provided through the heat-conducting device 2 to facilitate the sliding of the retaining plate 24. Spring clips 25 are provided on both sides of the retaining plate 24.

The interior of the placement box 52 has a storage space for storing paraffin-based phase change materials 56. When the engine cylinder head 1 temperature rises... The phase change material in the phase change material heat dissipation layer begins to absorb heat and undergo a phase change, changing from a solid to a liquid state. It absorbs a large amount of heat without significantly increasing the temperature, thereby effectively slowing down the temperature rise rate of the engine cylinder head 1. When the temperature of the engine cylinder head 1 decreases or enters the cooling stage, the phase change material begins to release heat and undergoes a reverse phase change, changing from a liquid to a solid state. It releases the previously absorbed heat into the environment, accelerating the cooling process of the engine cylinder head 1. The temperature of the equipment is monitored in real time by a temperature sensor. In addition, a slot 55 is provided at the upper end of the placement box 52, which can correspond one-to-one with the insert block 58 provided at the bottom of the cover plate 57, making it easy to close the cover plate 57.
