FAW J6P Радиатор: Деконструкция 46 Важные детали для безупречного управления температурным режимом

This is an expert deconstruction of the FAW J6P Радиатор сборка (Глава 37), the core of the thermal management system for the FAW Jiefang CA3250P66K2L1T1E 6×4 самосвал. This is not a single part but a complex, 46-компонент “Heat Exchange Logic” система. Its sole purpose is to protect the engine from catastrophic overheating under extreme, условия бездорожья.

The FAW J6P Радиатор system must manage multiple “Thermal Loads.” This includes the primary “Engine Cooling Logic” (dissipating heat from the 11-liter engine’s coolant) и “Charge Air Cooling Logic” (cooling the compressed air from the turbocharger via the intercooler). Any failure in this system—a pinhole leak from vibration, a failed clamp, or a cracked bracket—will lead to coolant loss, перегрев, and potential engine seizure.

This technical guide is a critical resource for chassis technicians, менеджеры по техническому обслуживанию автопарка, и специалисты по запчастям. We will analyze all 46 компоненты, breaking them down from the main assembly to the smallest serviceable units. We will cover the “Core Exchange Logic” (the radiator and shroud), а “Plumbing & Логика уплотнения” (all hoses, трубы, and clamps), и “Anti-Vibration Logic” (the complex system of brackets, поддерживает, and tie-rods).

Основной 1: The “Теплообмен & Расход воздуха” Логика (Компоненты 1, 2)

Эта группа является “рабочая лошадка” принадлежащий FAW J6P Радиатор система. It is where all heat dissipation occurs.

1. Компонент: ‘Radiator assy’ (1301010-14Б)
Этот (Комп 1) является основным “Heat Exchange Logic.” Эта сборка является FAW J6P Радиатор основной, combined with the “Charge Air Cooler” (Промежуточный охладитель). Это “сложенный” или “dual-circuit” дизайн.

The “Coolant Logic” is that hot (90°С+) engine coolant from the ‘Inlet hose’ (Комп 4) is pumped through fine-walled tubes. Воздух, pulled by the fan (Глава 20), rushes past these tubes and “wicks” the heat away.

The “Charge Air Logic” is that hot (150°С+) compressed air from the turbocharger is forced through a separate, parallel core. Этот “Intercooler Logic” cools and densifies the air before it enters the engine, which is critical for emissions control and engine power.

2. Компонент: ‘Fan shroud’ (1309010-14Б)
Этот (Комп 2) это “Airflow Funnel Logic.” A fan without a shroud is extremely inefficient, as it pulls air from the “path of least resistance” (the sides). This shroud’s “логика” is to create a “туннель,” forcing the fan to pull 100% of its air *through* the FAW J6P Радиатор плавники.

A crack or missing section of this shroud will cause a “hot spot” on the radiator core (where no air is being pulled), drastically reducing cooling efficiency and leading to overheating under heavy load (like climbing a grade).

Основной 2: The “Plumbing & Degassing” Логика (Шланги & Pipes)

Эта группа является “arterial network” that moves coolant and air. It is the most vulnerable part of the FAW J6P Радиатор system to “Smallest Serviceable Unit” failures like loose clamps.

1. The “Main Circulation Logic” (Компоненты 4, 6)
Это включает в себя ‘Radiator inlet hose’ (1303011-14Б) и ‘Radiator outlet hose’ (1303021-14Б). Это “Primary Arteries.” The ‘Inlet hose’ (Комп 4) carries 90°C+ coolant *from* the engine’s thermostat *to* the radiator. The ‘Outlet hose’ (Комп 6) returns the now-cooled (НАПРИМЕР., 80° C.) coolant *from* the radiator *back to* the ‘Water pump’ (Глава 19) to re-enter the engine block.

2. The “Обход & Возвратная логика” (Компоненты 30, 31, 37, 41)
This group includes the ‘Return water pipe’ (1311062-14Б), ‘Connection steel pipe assy’ (1311035-61Б), ‘Front return water pipe’ (1311034-61Б), и ‘Connecting pipe assy’ (1311025-61Б). Это “Обход логики” that allows coolant to circulate through systems like the cab heater core, even when the main thermostat is closed.

3. The “Intercooler Logic” (Компонент 28)
The ‘Intercooler connecting hose’ (1311034-50А) это “Charge Air Plumbing.” It connects the “холодная сторона” of the intercooler (part of the ‘Radiator assy’, Комп 1) to the engine’s intake manifold.

4. The “Degassing Logic” (Компоненты 17, 39, 40, 45, 46)
Это “System Breathing Logic.” This group includes the ‘Reservoir’ (1302052-01) (the expansion tank), ‘Radiator rear degas pipe’ (1311069-76А), ‘Radiator degas pipe’ (1311063-61Б), ‘Engine degas pipe assy’ (1311025-138), и ‘Degas air bleed bolt’ (1311024-249).

Air is the #1 enemy of a cooling system. Air bubbles create “steam pockets” that don’t transfer heat and cause “cavitation” that destroys the water pump. Этот “Degassing Logic” is a network of small pipes that “scavenge” any trapped air from the highest points (radiator top, engine head) and routes it to the ‘Reservoir’ (Комп 17), where it is safely vented. The ‘Degas air bleed bolt’ (Комп 45) это “Smallest Serviceable Unit” for mechanics to manually “истекать кровью” air after a coolant change.

Основной 3: The “Антивибрационный & Монтаж” Логика

This is the largest and arguably most critical group for the FAW J6P Радиатор‘s long-term survival. A radiator is heavy and made of “мягкий” materials (aluminum). The chassis of a dump truck flexes and vibrates violently. Эта группа является “Логика изоляции” that prevents the chassis from “рвущий” the radiator apart.

1. The “Main Support Logic” (Компоненты 11, 12, 13)
The ‘Radiator bottom crossmember assy’ (1302030-61Б) это “полка” that the entire FAW J6P Радиатор assembly sits on. The ‘Radiator left support’ (1302027-70ты) и ‘Radiator right support’ (1302028-70ты) являются основными “isolator” скобки, likely using rubber mounts (see Chapter 38) to absorb vibration.

2. The “Frame Tie-In Logic” (Компоненты 8, 22, 26, 33, 35)
Этот “Bracket Logic” group includes the ‘Radiator connecting plate assy’ (1301020-61Б), ‘Radiator support plate’ (1302040-14Б), ‘Support plate’ (1302043-14Б), «Поддержка в сборе’ (1311045-61Б), и ‘Radiator upper connecting plate’ (1301023-50А). Этот “сеть” of steel plates connects the “изолированный” radiator back to the “вибрирующий” truck frame, providing the necessary stiffness.

3. The “Anti-Sway Logic” (Компоненты 18, 19)
Это “Chassis-Flex Logic.” This group includes two ‘Tie rod assy’ (1302050-01) и два ‘Tie rod upper support’ (1302041-14Б). The ‘Tie rod’ (Комп 18) является “Anti-Sway Bar” for the radiator.

Когда грузовик врезается в выбоину, the entire cab (and the top of the radiator) wants to “sway” левый, while the chassis (and the bottom of the radiator) sways right. Этот “Shearing Force Logic” would instantly crack the plastic end-tanks of the FAW J6P Радиатор. Эти “Tie rods” are diagonal stabilizers that “замок” the top and bottom of the radiator, preventing this destructive “sway.”

4. The “Застежка & Clamp Logic” (The SSU)
This group includes all remaining “Smallest Serviceable Units.” The ‘Hose clamps’ (Комп 3, 5, 29, 38, 43) являются “Логика уплотнения” for the plumbing. A single failed clamp (НАПРИМЕР., Комп 5 on the ‘Outlet hose’) will cause a complete coolant “свалка” и катастрофический отказ двигателя.

The numerous ‘Bolts’ (Комп 7, 9, 10, 14, 15, 16, 23, 24, 32, 34, 36, 42) и ‘Nuts’ (Комп 20, 25, 27) являются “Логика виброустойчивого крепления.” Это высокопрочные, often “фланцевый” or used with ‘Spring washers’ (Комп 21) to prevent them from vibrating loose, which would lead to a component (как FAW J6P Радиатор) cracking from fatigue.
