Integrated HVAC & Intelligent Thermal Management Systems

Aotecar provides full-stack automotive HVAC and thermal management solutions, bridging the gap between cabin comfort and powertrain efficiency. By integrating advanced hardware with intelligent control logic, we deliver high-performance systems for both Internal Combustion Engine (ICE) vehicles and New Energy Vehicles (NEV). Our expertise spans the entire thermal loop—from air handling to complex refrigerant and coolant circuit management.

Front-end cooling module

This cooling module comprises components including the OHX, LTR, electric fan, air duct cover, and vibration damping pads.

Smart Aromatherapy Module

Our company's intelligent fragrance module not only achieves deep integration with the vehicle's smart cockpit, but also enables intelligent functions such as fragrance switching, concentration adjustment, and remaining quantity alerts via the central control screen interface. It can invigorate the mind, purify the air, and create a pleasant atmosphere, meeting diverse user needs while enhancing the vehicle's overall sense of luxury and technological sophistication.

Integrated Functional Module for Thermal Management in New Energy Vehicles

  • Major assembly incorporating refrigerant sub-module and coolant sub-module
  • Compatible with refrigerants R134a/R1234yf/R290
  • Maximum cooling capacity: 10kW; maximum heating capacity: 8kW
  • Compatible with 22kW low-temperature water tanks and 800W electronic fan heat pump systems

Thermal Management Controller

The thermal management controller serves as the “brain” of the new energy vehicle's thermal management system. It continuously monitors the temperatures of the battery, motor, and passenger compartment via sensor signals, precisely controlling actuators such as fans, water pumps, and compressors to maintain overall thermal equilibrium. This ensures vehicle safety, performance, and range.
