Embodiment Construction

[0011] The content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] Such as figure 1 As shown, the engine turbocharger cooling hose of the present invention is composed of an inner layer 1, an intermediate layer 2 and an outer layer 3; the inner layer 1, the intermediate layer 2 and the outer layer 3 are all concentric (or coaxial) cylinders. The inner layer 1 and the middle layer 2 are bonded to each other by heat pressing. The outer layer 3 is tightly sleeved on the outside of the middle layer 2, and the two are bonded to each other by an adhesive. Among them, the inner layer 1 is composed of 50-90% (by weight) of polytetrafluoroethylene, 5-30% of glass fiber and 0-20% of carbon fiber, which has certain high temperature resistance and cooling liquid resistance permeability. Preferably, the inner layer 1 can be made of 65-80% polytetrafluoroethylene, 10-25% glass fiber and 5-10% carb...

Abstract

The invention discloses a cooling hose for a turbocharger of an engine. The cooling hose consists of an inner layer, an interlayer and an outer layer, wherein the inner layer and the interlayer are bonded by hot-pressing; the interlayer and the outer layer are bonded through a binder; the inner layer is formed by compounding 50 to 90 weight percent of polytetrafluoroethylene, 5 to 30 weight percent of glass fiber and 0 to 20 weight percent of carbon fiber; the interlayer is woven from at least one of polyester fiber and aramid fiber; and the outer layer is formed by extruding and vulcanizing at least one of ethylene-propylene-diene monomer and neoprene. The cooling hose for the turbocharger of the engine is high in heat resistance and pressure resistance, and low in cooling liquid permeability; the problem of environmental aging of the hose is effectively solved; and the cooling hose is simple in structure and easy to manufacture.

Description

technical field [0001] The invention relates to rubber and plastic hoses, in particular to engine turbocharger cooling hoses. Background technique [0002] The engine turbocharger can increase the air density, increase the air quality entering the cylinder, and output more work under the condition that the engine structural parameters remain unchanged, which can greatly increase the specific power of the engine. In addition, the air volume in the cylinder increases after supercharging, and the excess air coefficient increases, which promotes the full combustion of fuel, improves the fuel economy and emission performance of the engine, and also suppresses combustion and exhaust noise to a certain extent. Therefore, the world's major automobile companies have invested a lot of manpower, material and financial resources in its research and development. [0003] Since the turbocharger of the engine will produce high-temperature and high-pressure gas during work, the gas tempera...
