Description
Technical Field
The utility model relates to a separate heat exchanger for automobile exhaust system.
Background
Approximately 30% of the waste heat is removed from the exhaust gases as the vehicle is driven forward by the vehicle's internal combustion engine. This portion of the exhaust gas, which is at an extremely high temperature, causes a high temperature radiation source to be formed throughout the exhaust system walls, radiating surrounding components and heating the air. The exhaust system generally comprises an exhaust pipe, a three-way catalyst, a muffler and the like, and exhaust gas flows through an exhaust manifold, a turbocharger and the whole exhaust system in the process of being exhausted to the atmosphere. The engine compartment and the chassis are relatively narrow in space, parts are inevitably arranged around the heat sources, when the distance does not meet the requirement, the temperature of the heated parts exceeds the bearable range, and the problem of irreversible heat damage occurs, so that the heat shield is required to insulate the heat sources to a certain extent. Most of the existing heat shields are made of single-layer aluminum plates or steel plates, and the heat insulation effect is poor.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a separate heat exchanger for automobile exhaust system can effectively improve thermal-insulated effect.
The technical scheme for realizing the purpose of the utility model is as follows:
the utility model provides a separate heat exchanger for automobile exhaust system, includes and separates the heat exchanger body, separate the heat exchanger body by the heat insulating board constitute, the heat insulating board comprises top layer, bottom and insulating layer, the insulating layer is located between top layer and the bottom, the insulating layer is equipped with a plurality of thermal-insulated cavities.
Furthermore, heat insulation plates are arranged in the heat insulation layer and distributed in a continuous square wave shape, and a plurality of continuous heat insulation chambers are formed between the heat insulation plates and the top layer and the bottom layer.
Furthermore, heat insulation plates are arranged in the heat insulation layer and distributed in a continuous zigzag manner, and a plurality of continuous heat insulation chambers are formed between the heat insulation plates and the top layer and the bottom layer.
Further, the top and bottom layers are made of aluminum-plated steel sheets.
Further, the heat insulation plate is made of a bent aluminum plate.
The utility model discloses beneficial effect who has:
the utility model discloses the heat insulating board comprises top layer, bottom and insulating layer, the insulating layer is located between top layer and the bottom, the insulating layer is equipped with a plurality of thermal-insulated cavities. The utility model discloses be equipped with thermal-insulated cavity in the heat insulating board, it is thermal-insulated through the air interlayer, effectively improved thermal-insulated effect, and low in manufacturing cost, easily installation processing.
In the utility model, the heat insulation layer is internally provided with a heat insulation plate which is distributed in a continuous square wave shape, and a plurality of continuous heat insulation chambers are formed between the heat insulation plate and the top layer and the bottom layer;
the heat insulation layer is internally provided with heat insulation plates which are distributed in a continuous zigzag manner, and a plurality of continuous heat insulation chambers are formed between the heat insulation plates and the top layer and the bottom layer. The utility model discloses a mode of setting up of above-mentioned heat insulating board realizes a plurality of thermal-insulated cavity settings, has further guaranteed thermal-insulated effect to easily processing.

fig. 2 is a schematic structural diagram of a second embodiment of the present invention.
Detailed Description
The first embodiment is as follows:
a heat shield for an automotive exhaust system includes a heat shield body comprised of a heat shield panel. As shown in fig. 1, the heat insulation board is composed of a top layer 1, a bottom layer 3 and a heat insulation layer, wherein the heat insulation layer is positioned between the top layer 1 and the bottom layer 3, and the heat insulation layer is provided with a plurality of heat insulation chambers. The heat insulation layer is internally provided with a heat insulation plate 2, the heat insulation plate 2 is distributed in a continuous square wave shape, and a plurality of continuous heat insulation chambers are formed between the heat insulation plate 2 and the top layer 1 and the bottom layer 3. The top layer 1 and the bottom layer 3 are made of aluminum-plated steel sheets. The heat insulation plate 2 is made of a bent aluminum plate.
The top layer 1 and the bottom layer 3 are made of aluminized steel plates, sufficient strength and reflectivity can be provided, and an air interlayer can be provided by a heat insulation chamber in the heat insulation layer, so that heat conduction between the two steel plates is weakened. The utility model discloses the installation can adopt welding or bolt fastening mode, can be used to thermal-insulated such as exhaust manifold, turbo charger and blast pipe.
Example two:
as shown in fig. 2, the difference between the second embodiment and the first embodiment is that the heat insulation boards 4 are distributed in a continuous zigzag shape, and a plurality of continuous heat insulation chambers are formed between the heat insulation boards and the top layer and the bottom layer. The rest of the structure of the second embodiment is the same as that of the first embodiment.
