ФАВ Воздуховод: The 5 Критически важные компоненты для безупречности, Полный климат-контроль в кабине

Welcome to this in-depth analysis of the ФАВ Воздуховод (Сборка 713) система. Это полный, 5-тип компонента, “air distribution network” для FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. Это “respiratory system” of the cab, а “логика” assembly designed to take the conditioned air (hot or cold) from the ‘Dual-zone box’ (Сборка 710) and deliver it to the correct locations.

The “логика” принадлежащий ФАВ Воздуховод system is “high-efficiency airflow.” It is a network of pre-molded, sealed plenums and channels that ensure the *maximum* volume of air from the ‘FAW Fan’ (Сборка 711) reaches its destination (windscreen, лицо, or feet) with *minimum* “pressure loss” или “leakage.” Этот “логика” is critical for fast defrosting and efficient A/C performance.

This expert guide is essential for HVAC technicians and parts managers. Мы разберем всю ФАВ Воздуховод сборка в свой 5 отдельные типы обслуживаемых компонентов. Мы проанализируем “Логика безопасности” (размораживать) of the side ducts, а “Comfort Logic” (face/central) of the main ducts, и “Полимер-безопасный” anti-rattle fastener system (Компонент 1) that holds it all together.

Основной 1: The “Безопасное размораживание” Логика (Компоненты 3 & 5) (The “дольше” Модуль)

The most critical components of the ФАВ Воздуховод system are those dedicated to safety. Это “dual-defrost” система, comprised of the ‘Left side door defrost… duct assy’ (8102065-B27-C00) and the ‘Right side door defrost… duct assy’ (8102070-B27-C00).

1. The “Ветровое стекло” Defrost Logic:

The primary “логика” of these ducts is to get hot, dry air from the ‘Heater Core’ (Сборка 709) to the ‘Front Windscreen’ (Сборка 630) as *fast* as possible. These ducts are the “сантехника” that connect the ‘Dual-zone box’ (710) to the long, thin vents at the base of the dashboard.

Их “логика” is to create a high-velocity, wide “sheet” of air that blows up the *inside* of the windscreen. Этот “heat transfer” logic is what melts ice and evaporates fog, making them the #1 active safety component in the HVAC system.

2. The “Side Window” Defrost Logic:

Это “secondary” and often-overlooked “логика” of these same components. The ‘Left/Right side door defrost’ ducts (Компоненты 3 & 5) являются “dual-outlet” ducts.

А “branch” или “порт” on each duct “логика” is designed to aim a *separate* stream of hot, dry air directly at the ‘Side Window’ (Сборка 634). Этот “side-defrost” logic is *critical* for a tractor. Its function is to keep the side window clear of fog and ice, specifically in the area *where the driver looks at the ‘Left/Right Hand Wing Mirror’ (Сборки 702 & 703)*.

Без этого “mirror-clearing” логика, the driver would be “blind” in a snowstorm, unable to see their blind spots for a safe lane change. This makes these components a key part of the vehicle’s “active safety” система.

3. The “Molded-Fit” Логика:

Эти ФАВ Воздуховод components are not simple, round tubes. They are complex, 3Д, “blow-molded” shapes. Их “логика” is to be *invisible*. Они предназначены для “snake” through the extremely tight, confined spaces *inside* the ‘Dashboard Components’ (Сборка 647) and around the ‘Welded Cab Assembly’ (617) A-pillars.

They are made from a high-temperature, rigid polymer that is “акустически мертвый” to prevent “свист” шумы. A failure of one of these ducts (cracked from a bad repair, или “pinched” тюлень) will cause a “утечка” *inside* the dashboard, resulting in weak defrost performance and a “foggy” окно, even when the ‘FAW Fan’ (711) is on high.

Основной 2: The “Driver Comfort” Логика (Компоненты 2 & 4)

This group of components is the “комфорт” логика ФАВ Воздуховод система.

Компонент 2: ‘Face air duct assy’ (8102010-B27-C00)

Компонент 4: ‘Central air duct transition assy’ (8102050-B27-C00)

The “логика” of this pair is to deliver high-volume, conditioned air to the *driver’s face and torso*. The ‘Central air duct’ (Компонент 4) это “trunk” системы, большой “plenum” that takes the main “лицо” output from the ‘Dual-zone box’ (710).

The ‘Face air duct’ (Компонент 2) это “branch” that connects this central plenum to the dashboard’s directional vents. The “логика” of these ducts is “высокопоточный, low-noise.” Their inner surfaces are engineered to be smooth, с “radiused” (curved) bends instead of sharp corners. Этот “laminar flow” logic allows the ‘FAW Fan’ (711) to deliver a high-velocity stream of cold air to the driver *without* an annoying “шипение” или “свист” звук.

Основной 3: The “Полимер-безопасный” Логика крепления (Компонент 1)

The final component of the ФАВ Воздуховод assembly is the 15-piece fastener kit, ‘Cross recessed pan head self-tapping screw and plain washer assy’ (002214216F6).

“Полимер-безопасный” Логика: Это “installation logic” для всей системы. All the ducts (Компоненты 2, 3, 4, 5) являются “мягкий” polymer. They must be fastened to “жесткий” mounting points on the ‘Dashboard Components’ (647) and the ‘Dual-zone box’ (710).

This fastener system is a “двойная логика” компонент:

• “Саморезы” Логика: The “винт” part is “саморез” (Саморезы). It is designed to cut its own threads into the plastic “flanges” of the ducts, создание плотного, vibration-resistant connection without a “nut.”
• “Шайба” Логика: The “plain washer assy” (平垫圈组合) is the *critical* “логика.” A screw head alone would “pinch” and *crack* the plastic duct flange. Шайба “логика” is to *distribute the load* over a wide surface, allowing the screw to be tightened securely *without* damaging the part.

This 15-point “антивибрационный” и “anti-crack” logic is what ensures the ФАВ Воздуховод system remains sealed, тихий, и “rattle-free” for the life of the cab.
