Gas exhaust and heat insulation plate

Abstract

The invention relates to a gas exhaust and heat insulation plate, which consists of a gas exhaust pipe and a heat insulation plate and is characterized in that: the heat insulation plate is arranged on the gas exhaust pipe, the heat insulation plate is partially surrounded at the circumference of the gas exhaust pipe, and a gap is reserved between the heat insulation plate and the gas exhaust pipe. The gas exhaust and heat insulation plate has the advantages of good heat insulation effect, small and exquisite and simple structure, space saving, arrangement flexibility, simple process, easiness in manufacturing, high reliability, low manufacturing cost, high economy, and the like.

Description

technical field [0001] The invention belongs to the technical field of exhaust heat insulation boards for automobiles, and in particular relates to a novel exhaust heat insulation board. Background technique [0002] At present, exhaust heat shields are roughly divided into two categories: one is fixed to the body floor and wraps the body floor; the other is to wrap the exhaust manifold, catalytic converter and exhaust pipe, and use To heat and insulate. [0003] The above two types of heat shields are currently commonly used types, but we often encounter this situation: due to insufficient layout space, a few or a single part is very close to the equidistant exhaust pipe, in order to prevent these parts from being heated, heat shields are needed To separate these parts from the exhaust pipe, the traditional method is: one is to wrap these parts with a heat shield, but the disadvantage of this method is that the required heat shield area is large, and the space itself is no...

[0003] The above two types of heat shields are currently commonly used types, but we often encounter this situation: due to insufficient layout space, a few or a single part is very close to the equidistant exhaust pipe, in order to prevent these parts from being heated, heat shields are needed To separate these parts from the exhaust pipe, the traditional method is: one is to wrap these parts with a heat shield, but the disadvantage of this method is that the required heat shield area is large, and the space itself is not enough to fix the heat shield layout. Difficult and lead to complex structure of the heat shield, high cost, and easy to cause vibration; the second is to wrap the entire circumference of the exhaust pipe close to these parts. The disadvantage of this method is that the heat shield needs to be divided into upper and lower parts for use. Bolts are tightened and fixed, resulting in more parts, higher manufacturing costs, and increased complexity of process assembly
