Engineered for extreme duty, the WG1642820047 HOWO condenser assembly (Shiyan Ruigao) delivers unmatched cooling performance. As a critical component for Howo/Sitrak truck parts, this condenser ensures your fleet stays productive even under the harshest operating conditions. Precision-manufactured to OEM specifications, it guarantees a perfect fit and long‑lasting reliability.
Designed for the most demanding logistics and construction applications, the WG1642820047 condenser assembly combines robust construction with advanced heat dissipation. Manufactured by Shiyan Ruigao, a trusted name in heavy‑duty thermal solutions, this unit mirrors the original equipment standard. Every detail – from the microchannel core to the corrosion‑resistant coating – is optimized for maximum durability and cooling capacity. Whether you operate a HOWO T7, A7, or Sitrak C7H, this condenser ensures your cabin climate stays comfortable and your engine runs within ideal temperature ranges.
The WG1642820047 utilizes a high‑density fin and tube geometry that increases surface area by 18% compared to standard designs. This translates into faster refrigerant phase change and lower discharge pressures, reducing compressor workload and improving fuel economy.
Every WG1642820047 unit is treated with a multi‑layer epoxy coating and features double‑rolled tube ends. This prevents galvanic corrosion and refrigerant leakage, even when exposed to road salts, dust, and humidity.
Developed from original HOWO blueprints, the WG1642820047 condenser assembly offers plug‑and‑play installation. All mounting brackets, O‑ring grooves, and port orientations match the factory dimensions – no modifications needed.
Rigorously tested under extreme ambient temperatures (up to 55°C) and vibration loads, the WG1642820047 maintains stable subcooling and air‑side delta T. It outperforms generic aftermarket units by a significant margin.
The microchannel design of the WG1642820047 reduces refrigerant charge by up to 25% while delivering 30% higher heat transfer efficiency. This is achieved through parallel flow circuits that minimize pressure drop and maximize contact with ambient air.
Shiyan Ruigao utilizes aerospace‑grade aluminum brazing, ensuring the core withstands thermal cycling without fatigue. The WG1642820047 also includes a built‑in receiver drier bracket, simplifying system integration.

The WG1642820047 condenser assembly has been validated on HOWO T5G, T7H, and Sitrak C7H platforms. Its performance consistency is backed by thousands of fleet hours across mining, long‑haul, and construction applications.
When you invest in the WG1642820047, you’re not just buying a replacement part – you’re securing the thermal heart of your truck’s HVAC system. The condenser’s advanced louvered fins create turbulent airflow, which dramatically improves heat transfer even at low vehicle speeds. In stop‑and‑go traffic or idle conditions, the WG1642820047 maintains a stable condensing temperature, preventing the AC compressor from cycling excessively. This extends the life of the entire AC system, including the compressor, dryer, and expansion valve.
Shiyan Ruigao’s manufacturing process involves strict quality gates: incoming material inspection, in‑process brazing control, and final performance testing on a calorimeter bench. Every unit is serial‑tracked, ensuring full traceability. The use of high‑purity aluminum and controlled atmosphere brazing eliminates oxidation and ensures consistent joint strength. This attention to detail results in a condenser that not only cools effectively but also resists mechanical stress from road impacts and frame flexing.
Fleet managers have reported a 12‑15% reduction in AC‑related downtime after switching to the condenser. The robust brazed joints and anti‑vibration mounts eliminate common failure points like cracked tubes or loose fittings. Moreover, the condenser’s compact footprint leaves ample space for auxiliary coolers, making it an ideal choice for heavy haulers and vocational trucks that require additional cooling for hydraulic systems or auxiliary engines.
From a maintenance perspective, the features easily accessible service ports and a sight glass for quick refrigerant level checks. The integrated desiccant filter can be replaced without removing the entire assembly, saving labor hours during routine service intervals. This thoughtful design aligns with the operational realities of modern logistics, where every minute of uptime matters.
In summary, the condenser assembly from Shiyan Ruigao represents a perfect synergy of OEM precision and aftermarket value. Its microchannel core, corrosion protection, and exact fitment make it a standout upgrade for any HOWO or Sitrak truck. Whether you are replacing a worn unit or upgrading your fleet’s cooling capacity, the delivers consistent, reliable performance in all climates. Backed by rigorous testing and a commitment to quality, this condenser ensures that your cabin remains cool, your engine stays protected, and your operation runs smoothly mile after mile.
