Engine cabin firewall

Abstract

The invention discloses an engine cabin firewall and relates to the technical field of engine cabins. The engine cabin firewall comprises a main body and second pipeline connection mouths, wherein theupper end of the front face of the main body is provided with a first pipeline connection mouth, the second pipeline connection mouths are arranged in the lower end of the front face of the main body, the first pipeline connection mouth and the second pipeline connection mouths are both fixedly connected with the main body by pouring, and a valve body installation mouth is arranged right below the first pipeline connection mouth. The engine cabin firewall has the beneficial effects that by means of the arrangements of polyurethane layers, the engine cabin firewall is made to have the effectsof ageing resistance, watertightness, temperature insulation, good softness and sound insulation; meanwhile, by means of the arrangements of ventilation holes of hollow structures, mutual convection current between the inner portion of the engine cabin firewall and the outside air can be facilitated, and unpleasant odor generated in the pouring process of the whole engine cabin firewall also willbe brought out accordingly; and by means of the arrangements of seal cover plates capable of overturning, the sealing and sheltering effects can be performed on the arrangement of an air-conditioningcondensing pipe, and interference of external factors on multiple refrigeration operations is prevented.

Description

technical field [0001] The invention relates to the technical field of an engine compartment, in particular to an engine compartment firewall. Background technique [0002] The engine compartment generally includes the engine, air filter, battery, engine exhaust system, throttle valve, water tank replenishment tank, relay box, brake booster pump, throttle cable, window glass washer fluid storage tank, brake fluid storage tank, etc. Liquid tanks, fuses, etc. The firewall on the car refers to the fireproof material installed inside and outside the dash panel. The firewall is used in the engine compartment, under the front block, made of asbestos, and inside the instrument panel. The firewall is generally made of high temperature resistant materials. During the process, pouring is carried out on the corresponding mold. The pouring process of the firewall is to firstly absorb the 0.025MM PU film on the mold with vacuum adsorption method, and then inject PU raw material (polyuret...

Problems solved by technology

[0004] The object of the present invention is to provide a fire wall for the engine compartment to solve the problem that the surface of the existing fire wall proposed in the above-mentioned background technology will be discolored and discolored due to excessive use of the device during the installation of auxiliary air-conditioning parts and cooling operation. Brittleness, loss of strength and other aging phenomena, while the general firewall material is too hard, it is extremely easy to endanger the personal safety of the human body due to collision
