Description

Technical Field

[0001] This utility model relates to the technical field of heat shields, and in particular to a heat shield assembly for a gas engine turbocharger. Background Technology

[0002] The turbocharger heat shield assembly is a metal housing installed on the hot end of the turbocharger (mainly the turbine housing). Its core functions are heat insulation, protection, and noise reduction. By effectively blocking the enormous heat generated during turbocharger operation, it protects surrounding components (such as wiring harnesses, sensors, hoses, and other engine accessories) from heat radiation damage, while also reducing the surface temperature of the engine compartment, thus improving safety and reliability.

[0003] In existing technologies, to improve the service life of heat shields, they are typically made of metal, which is also an excellent thermal conductor. Therefore, heat shields are often filled with insulating material to maintain their insulation performance. However, after prolonged use, the insulating material may compact or pulverize due to vibration, leading to a decrease in insulation effectiveness. Therefore, the insulating material needs regular maintenance and replacement. Furthermore, turbochargers are typically volute-shaped, and their matching heat shields are also volute-shaped. This increases the difficulty of filling the heat shield with insulating material, affecting its maintenance. Utility Model Content

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A gas engine turbocharger heat shield assembly, comprising: The housing has a receiving groove on the side near the turbocharger; Thermal insulation material, which is placed in the receiving groove for thermal insulation; There are two support rails, which are respectively set on opposite sides of the receiving groove to support the thermal insulation material; An auxiliary unit, which is slidably connected to the bottom of the receiving groove, is used to assist in the installation of thermal insulation material.

[0005] Furthermore, the auxiliary unit includes a slider and a connecting rod. There are two sliders, and a connecting rod is fixedly connected to one side of each slider. The ends of the two connecting rods away from the sliders are hinged.

[0006] Furthermore, rollers are connected to the side of the slider that is close to the support rail and the receiving groove.

[0007] Furthermore, the slider has a connection hole on the side near the heat insulation material, and the bottom of the heat insulation material is connected to a connecting shaft for inserting into the connection hole.

[0008] Furthermore, the heat insulation material has a protrusion on the side near the support track groove to form a support portion for insertion into the track.

[0009] Furthermore, the top and bottom of the insulation material have spaces between them and the opening and bottom wall of the receiving groove, respectively, for forming an air insulation layer.

[0010] In summary, this utility model has at least one of the following beneficial technical effects: This gas engine turbocharger heat shield assembly, through the setting of support rails and auxiliary units, can improve the installation efficiency of heat insulation material during installation. Furthermore, the sliding auxiliary unit can also use the sliding of the auxiliary material to perfectly install the heat insulation material into the receiving groove when the heat insulation material is pressed into the arc section, thereby improving the installation and replacement efficiency of the heat insulation material inside the heat shield.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Example: Reference Figure 1 - Figure 4 The present invention discloses a gas engine turbocharger heat shield assembly, comprising: The housing 1 has a receiving groove 5 on the side near the turbocharger; Insulation material 2 is placed inside the receiving groove 5 for insulation purposes; There are two support rails 3, which are respectively set on opposite sides of the receiving groove 5 to support the heat insulation material 2. Auxiliary unit 4, which is slidably connected to the bottom of receiving groove 5, is used to assist in the installation of thermal insulation material 2.

[0019] In this embodiment, observation Figure 1 It can be seen that by setting up a housing 1, a receiving groove 5 is opened on the side of the housing 1 near the supercharger, which can be used to hold the heat insulation material 2. At the same time, a support rail 3 is also set in the receiving groove 5 to support the heat insulation material 2, so as to ensure the installation stability of the heat insulation material 2.

[0020] Since turbochargers are usually volute-shaped, and their matching heat shields are also volute-shaped, it is more difficult to fill the heat shield with heat insulation material, which affects the maintenance of the heat shield.

[0021] Therefore, observe Figure 2 It can also be found that an auxiliary unit 4 is set at the bottom of the receiving groove 5. When installing the heat insulation material 2, it is only necessary to connect the heat insulation material 2 to the auxiliary unit 4, and then continuously press the heat insulation material 2 into the receiving groove 5. When the heat insulation material 2 is pressed into the arc section, the auxiliary unit 4 can slide along the arc section, so that the heat insulation material can be pressed into the receiving groove 5 more efficiently. This solves the problems of installation difficulties, low efficiency and easy damage to heat insulation materials caused by the small operating space and obstructed vision in the traditional method, and can effectively improve the installation and replacement efficiency of heat insulation materials.

[0022] In a further preferred embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the auxiliary unit 4 includes sliders 41 and connecting rods 42. Two sliders 41 are provided, and each slider 41 has a connecting rod 42 fixedly connected to its opposite side. The ends of the two connecting rods 42 away from the sliders 41 are hinged. The two sliders 41 are connected by a hinged connecting rod 42, forming a simple "four-bar linkage" or "linkage frame." Its core function is to maintain the synchronization and stability of the two sliders. When the heat insulation material 2 is pushed into the receiving groove 5 of the housing 1, especially in the arc-shaped housing 1, the two sliders 41 may experience a speed difference due to different resistance. The hinged connecting rod 42 allows for a small relative displacement between the two sliders 41, thereby adapting to the arc-shaped path within the housing 1. This effectively prevents a single slider 41 from jamming or the entire assembly from tipping over or twisting due to uneven force, ensuring a smooth installation process.

[0023] In a further preferred embodiment of this utility model, such as Figure 3 and Figure 4 As shown, rollers 6 are connected to both sides of the slider 41 near the support rail 3 and the receiving groove 5. The function of the rollers 6 is to convert the sliding friction between the slider 41 and the support rail 3 and the bottom wall of the receiving groove 5 into rolling friction. This brings two major benefits: First, it greatly reduces the installation thrust, allowing the operator to easily push the heat insulation material 2 into place, reducing labor intensity and improving assembly efficiency; second, it reduces wear on the support rail 3 and the bottom wall of the housing, avoiding metal shavings generated by friction, ensuring the long-term reliability of the product and maintaining the cleanliness of the engine compartment.

[0024] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the slider 41 has a connecting hole 7 on the side near the heat insulation material 2. The bottom of the heat insulation material 2 is connected to a connecting shaft 8 for insertion into the connecting hole 7. The connecting hole 7 and the connecting shaft 8 form a quick, reliable, and separable connection interface. Before installation, simply align the connecting shaft 8 at the bottom of the heat insulation material 2 and insert it into the connecting hole 7 of the slider to pre-fix both. This ensures that during the pushing process, the heat insulation material 2 and the auxiliary unit 4 become a single unit, moving synchronously without relative displacement or detachment. Once the heat insulation material 2 is finally installed in place, this connection structure also facilitates separation for maintenance, demonstrating the maintainability of the design.

[0025] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the thermal insulation material 2 has a protrusion on the side near the groove of the support rail 3, forming a support portion 9 for insertion into the rail. The support portion 9 (typically designed as a "flange" or "slide" matching the shape of the rail) cooperates with the support rail 3, playing a crucial role in radial positioning and load-bearing. This allows the weight of the thermal insulation material 2 to be transferred to the robust support rail 3 through the support portion 9, rather than relying entirely on the auxiliary unit 4 at the bottom. This not only distributes the load but, more importantly, prevents the thermal insulation material 2 from lateral swaying or detaching from the housing 1 due to vibration during vehicle operation, greatly enhancing the structural stability and durability of the entire assembly under harsh operating conditions.

[0026] In a further preferred embodiment of this utility model, such as Figure 1As shown, spaces are left between the top and bottom of the insulation material 2 and the opening and bottom wall of the receiving groove 5, respectively, to form an air insulation layer. This design utilizes the basic principle that "air is an excellent thermal insulator." The reserved spaces form one or more closed, stagnant air layers. Heat transfer occurs in three ways: conduction, convection, and radiation. This stagnant air layer effectively blocks heat conduction, and due to the sealed space, heat exchange caused by air convection is avoided. This is equivalent to adding an extra layer of highly efficient thermal insulation barrier on top of the insulation material 2 itself, achieving a synergistic effect of "material insulation" and "air insulation," thereby significantly improving the overall thermal insulation performance of the entire insulation cover assembly and more effectively reducing the temperature of the outer surface of the shell 1.

[0027] The implementation principle of the above embodiment is as follows: During assembly, the connecting shaft 8 at the bottom of the heat insulation material 2 is first inserted into the connecting hole 7 of the slider 41 of the auxiliary unit 4 for pre-fixation. Then, the support parts 9 on both sides of the heat insulation material 2 are aligned and placed on the support rail 3 of the housing 1. The operator applies a pushing force to the heat insulation material 2, causing it to slide along the support rail 3 into the receiving groove 5. During this process, the roller 6 at the bottom of the slider 41 rolls on the bottom wall of the receiving groove 5, converting sliding friction into rolling friction, making pushing easier; simultaneously, the hinged connecting rod 42 connecting the two sliders 41 ensures that the two sliders can adapt to the trajectory and remain stable when passing through the arc section of the housing, preventing jamming. After the heat insulation material 2 is pushed to the designed position, it is suspended on the support rail 3 by the support parts 9, achieving precise positioning and reliable fixation. Finally, the air insulation layer formed between the heat insulation material 2 and the housing 1, together with the heat insulation material 2 itself, constitutes a highly efficient composite heat insulation system.

[0028] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
