The global automotive industry is undergoing its most significant evolution in a century. Modern vehicle architectures require comprehensive integrated Thermal Management Systems (TMS) rather than isolated cabin heating and cooling units. The growth of Electric Vehicles (EVs) has changed the function of the standard HVAC system from a luxury comfort feature to a critical component of battery performance, powertrain durability, and driving range.
Unlike internal combustion engine (ICE) vehicles, which utilize waste heat from the engine to heat the cabin, EVs rely on heat pump cycles, Positive Temperature Coefficient (PTC) heaters, and coolant-based thermal loops. Consequently, global tier-1 suppliers and OEMs look to Chinese factories for key HVAC components, custom-milled connectors, and integrated power modules that support higher voltages and complex refrigerant routing.

From conceptual drawings to precise metal samples using advanced 5-axis CNC machining, ensuring immediate physical verification for custom vehicle integrations.
Deploying CMM (Coordinate Measuring Machines), optical comparators, and automated leak testers for absolute durability across high-pressure coolant loops.
Expertise in thermal-electronic convergence, developing and manufacturing robust DC-DC and AC-DC modules key for electrical air conditioning units.
Inside our high-precision production facility: advanced automated assembly, precision metal extrusion processing, and multi-stage quality control stations.
In modern vehicles, specifically high-range electric cars and plug-in hybrids, the HVAC system is no longer standalone. It interfaces with the battery chillers, electric motor cooling loops, and high-voltage electronics. This creates a multi-directional heating and cooling network requiring sophisticated valves and specialized manifolds.
Traditional PTC heaters consume substantial battery energy, reducing driving range in cold weather by up to 40%. Our partner engineering firms use advanced heat pump systems that capture ambient air energy and waste heat from electric motors. By implementing R134a or eco-friendly R1234yf refrigerants, these systems maintain cabin comfort while maximizing battery range.
Refrigerant routing requires durable connectors that resist leakage. Under Dongguan SHE Auto’s custom manufacturing capabilities, we supply high-tolerance fluid block connectors, custom sensor manifolds, and evaporator pipes. The structural integrity of these parts prevents fluid loss and maintains system pressure over years of high-vibration vehicle operation.
Electric HVAC compressors run on high-voltage DC current. Reliable, high-efficiency power modules—such as DC-DC converters and AC-DC modules—are critical to maintain stable power distribution between the main traction battery and auxiliary electronics (compressors, blowers, sensors). Dongguan SHE Auto specializes in high-durability power modules designed to operate under wide temperature variations, ensuring consistent HVAC system operation.
When international Tier-1 automotive brands source components from China, compliance and engineering standards are critical factors. An automotive component must withstand rigorous testing protocols before integration into final assembly lines.
Dongguan SHE Auto Co., Ltd. uses standardized process controls to ensure global compliance. Our custom component service offers a reliable supply chain for HVAC system manufacturers, vehicle converters, and automotive aftermarket distributors.
