Description

Technical Field

[0001] This utility model relates to the field of turbocharger technology, and in particular to a turbocharger heat insulation device. Background Technology

[0002] A turbocharger is a device that uses the energy of exhaust gases from an engine to drive an air compressor. It is mainly used to increase the intake air volume of the engine, thereby improving the engine's output power and efficiency. A turbocharger heat shield, also known as a turbocharger heat shield, is a protective cover installed around the turbocharger. Its main function is to reduce the impact of high-temperature exhaust gases on the turbocharger, thereby improving the engine's working efficiency and performance. Heat shields are usually made of metal materials such as stainless steel or aluminum alloy. These materials have excellent high-temperature resistance and corrosion resistance, and can withstand the working conditions of the engine in a high-temperature environment, protecting the turbocharger from hot gas corrosion.

[0003] Most turbocharger heat insulation devices on the market currently have poor heat insulation and heat resistance, which affects their performance. They also make it inconvenient for operators to disassemble and replace, increasing the workload for operators when installing and removing them. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given that most turbocharger heat insulation devices on the market, as described above or in the prior art, have poor heat insulation and heat resistance, thus affecting their performance, and are inconvenient for operators to disassemble and replace, thereby increasing the labor intensity of operators when installing and removing the heat insulation devices, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a turbocharger heat insulation device.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1: Refer to Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a turbocharger heat insulation device, which can achieve the effect of most turbocharger heat insulation devices on the market. However, most turbocharger heat insulation devices have poor heat insulation and heat resistance, which affects the performance of the turbocharger heat insulation device. At the same time, it is inconvenient for operators to disassemble and replace the turbocharger heat insulation device, which increases the labor intensity of operators when installing and disassembling the turbocharger heat insulation device. It includes a turbocharger body 1, which includes a central coaxial body 101. A turbine body 102 is installed at one end of the central coaxial body 101. A compressor body 103 is installed at the end of the central coaxial body 101 away from the turbine body 102. An exhaust pipe 104 is installed at the top of the turbine body 102.

[0030] The heat insulation mechanism 2 includes a first heat insulation pad 201 and a second heat insulation pad 202. The sidewalls of the first heat insulation pad 201 are provided with mounting grooves 2011, and the top and bottom ends of the mounting grooves 2011 are provided with limiting grooves 2012. The second heat insulation pad 202 is installed inside a mounting block 2021, and the top and bottom ends of the mounting block 2021 are provided with mounting chambers 2022. The mounting chambers 2022 are provided inside a limiting block 2025, and the limiting block 2025 is engaged with the limiting groove 2012. The guide wheel body 2028 is rotatably installed inside the second heat insulation pad 202. The bottom end of the limiting block 2025 is provided with a steel wire rope body 2027 that passes through the guide wheel body 2028.

[0031] The installation chamber 2022 has slide rails 2023 installed on both sides of its interior. The slide rails 2023 have sliders 2024 installed inside them. The end of the slider 2024 away from the slide rails 2023 is fixedly connected to the side wall of the limiting block 2025. The bottom of the installation chamber 2022 has a spring body 2026 installed inside it. The top of the spring body 2026 is fixedly connected to the bottom of the limiting block 2025. The installation block 2021 has a rotating rod body 2029 that passes through the second heat insulation pad 202 installed inside it via a bearing. The outer wall of the rotating rod body 2029 has a winding wheel 20291 installed. The winding wheel 20291 is fixedly connected to the wire rope body 2027.

[0032] The specific working principle is as follows: when the second heat insulation pad 202 and the first heat insulation pad 201 need to be installed and disassembled, the rotating rod body 2029 is first rotated to drive the winding wheel 20291 to wind the wire rope body 2027. Through the cooperation of the slide rail 2023 and the slider 2024, the wire rope body 2027 is wound to pull the limiting block 2025, causing the slider 2024 to slide inside the slide rail 2023 and compress the spring body 2026 to deform. At the same time, the limiting block 2025 and the limiting groove 2012 are engaged with each other, which makes it easy for the operator to install and disassemble the second heat insulation pad 202 and the first heat insulation pad 201, thus making the operation easier for the operator and reducing the labor intensity of the operator.

[0033] Example 2: Refer to Figures 1-5This is the first embodiment of the present invention. This embodiment provides a turbocharger heat insulation device, which can overcome the shortcomings of most turbocharger heat insulation devices currently on the market. These devices have poor heat insulation and heat resistance, which affects their performance. They are also inconvenient for operators to disassemble and replace, increasing the labor intensity of operators when installing and disassembling the turbocharger heat insulation device. The heat insulation mechanism 2 includes an anti-corrosion layer 222, a first heat-resistant layer 223 at the bottom of the anti-corrosion layer 222, a solid layer 224 at the bottom of the first heat-resistant layer 223, a sound insulation layer 225 at the bottom of the solid layer 224, and a second heat-resistant layer 226 at the bottom of the sound insulation layer 225. The solid layer 224 has reinforcing ribs 2241 arranged horizontally and interlaced inside, and the reinforcing ribs 2241 are made of glass fiber. The sound insulation layer 225 has sound-absorbing holes 2251 inside.

[0034] The specific working principle is as follows: First, the first heat-resistant layer 223 is made of aerogel, and the second heat-resistant layer 226 is made of glass fiber. The heat-resistant layer 226 and the first heat-resistant layer 223 together improve the heat resistance and heat insulation effect of the heat insulation mechanism 2. At the same time, the sound insulation layer 225 has sound-absorbing holes 2251 inside, and the sound insulation layer 225 is made of polyester chemical fiber. The sound insulation layer 225 and the sound-absorbing holes 2251 together improve the sound absorption effect of the heat insulation mechanism 2.
