Additionally, aluminum alloy has excellent formability, allowing for the precise manufacturing of thin-walled tubes and fins that maximize the heat exchange surface area. The end tanks (inlet and outlet chambers) of the warmer core are made of high-impact resistant plastic (PA66+GF30), which offers superior mechanical strength, resistance to coolant corrosion, and compatibility with the H230’s HVAC housing mounting structure. The plastic end tanks are engineered to withstand the pressure of the engine’s coolant system (typically 0.8-1.2 bar) and the thermal stress generated during heat exchange cycles.
To further enhance the performance and durability of the 710901900020 Warmer Core Assy, it undergoes a series of specialized surface treatments and manufacturing processes. The aluminum heat exchange tubes and fins are treated with a corrosion-resistant coating (chromate conversion coating), which prevents oxidation and corrosion caused by long-term contact with engine coolant and air moisture. This coating also improves the heat transfer efficiency by reducing surface resistance. The plastic end tanks are subjected to a high-temperature injection molding process, ensuring precise dimensional accuracy and a tight seal with the aluminum heat exchange core. Additionally, the entire assembly undergoes a vacuum brazing process, which securely bonds the aluminum tubes and fins together, creating a leak-proof and thermally efficient heat exchange structure.
The manufacturing process of the 710901900020 follows a strict, ISO 9001 and IATF 16949 certified production workflow, combining precision machining, automated assembly, and rigorous quality control—consistent with modern automotive HVAC component manufacturing standards. The production process begins with the preparation of raw materials: high-purity aluminum alloy sheets and tubes are selected and inspected to ensure they meet Brilliance’s material standards for thermal conductivity and mechanical strength. The aluminum sheets are then precision cut and formed into thin fins with micro-channels, which are designed to maximize the heat exchange surface area while minimizing air resistance. The aluminum tubes are bent into the required shape (typically a serpentine or U-shape) to fit the H230’s HVAC housing, ensuring optimal use of space and efficient coolant flow.
After forming, the aluminum tubes and fins are assembled into the core heat exchange structure and bonded using vacuum brazing. This process involves heating the assembly in a vacuum furnace to a temperature of 580-600°C, which melts the brazing alloy and creates a strong, leak-proof bond between the tubes and fins.

The aluminum heat exchange core is the central component of the 710901900020, responsible for transferring heat from the engine coolant to the air blown by the HVAC blower. It features a compact, serpentine tube design with closely spaced aluminum fins, which maximizes the heat exchange surface area while minimizing the overall size of the assembly—critical for fitting within the limited space of the H230’s HVAC housing. The serpentine tube design ensures that the hot coolant flows through a long, continuous path, allowing for sufficient heat transfer to the surrounding fins. The aluminum fins are arranged in a dense pattern, creating a large surface area for heat exchange between the coolant and the air. The fins are also designed with micro-channels, which enhance air flow and improve heat transfer efficiency by reducing air resistance and increasing turbulence.
The plastic end tanks (inlet and outlet) are attached to the top and bottom of the aluminum heat exchange core, serving as chambers that distribute the hot coolant into the serpentine tubes and collect the cooled coolant after heat exchange. The inlet end tank is connected to the engine’s coolant outlet pipeline, receiving hot coolant directly from the engine. The outlet end tank is connected to the engine’s coolant return pipeline, sending the cooled coolant back to the engine for reheating. Both end tanks are designed with internal baffles, which ensure uniform distribution of coolant throughout the serpentine tubes, preventing dead zones and ensuring consistent heat exchange across the entire core. The end tanks also feature precision-machined coolant ports, which are designed to match the H230’s coolant hoses, ensuring a tight, leak-proof connection.
The coolant inlet and outlet ports are integral components of the end tanks, designed with a quick-connect or clamp-on design to facilitate easy installation and removal. The ports are made of reinforced plastic, which is resistant to coolant corrosion and thermal stress, ensuring long-term reliability. The ports are also equipped with O-rings or gaskets, which provide an additional seal to prevent coolant leakage. The mounting brackets are integrated into the plastic end tanks, designed to match the mounting points in the H230’s HVAC housing. The brackets are made of high-strength plastic, ensuring a secure attachment that can withstand the vibration and thermal stress generated during vehicle operation. The mounting design also allows for easy installation and removal, reducing the time and effort required for replacement.
Another key design feature of the 710901900020 Warmer Core Assy is its compatibility with the H230’s HVAC temperature control system. The warmer core is positioned in the HVAC air duct, directly in the path of the air blown by the blower motor. A temperature control door (blend door) adjusts the amount of air that passes through the warmer core, allowing the driver and passengers to regulate the cabin temperature. The compact design of the 710901900020 ensures that it fits perfectly within the air duct, maximizing the amount of air that comes into contact with the heat exchange core and ensuring efficient heat transfer. Additionally, the warmer core is designed with a drainage hole, which allows any condensed moisture (resulting from the heat exchange process) to drain out of the HVAC system, preventing dampness and mold in the cabin.
