Description

Technical Field

[0001] This utility model relates to the technical field of parking heater motor assembly, and in particular to an integrated motor assembly. Background Technology

[0002] In harsh winter conditions, heating the cab of a diesel vehicle while parked presents significant challenges. Traditional solutions typically rely on starting the engine, allowing the antifreeze to heat up and then transfer heat to the cab via the vehicle's heating system. However, this method has several inherent drawbacks: First, the engine needs to idle for an extended period, leading to significant fuel consumption, especially at low temperatures where fuel efficiency further decreases, resulting in energy waste. Second, due to the slow engine start-up process and limited heat exchange efficiency, it often takes a considerable amount of time for the cab temperature to rise to a comfortable range, failing to meet the user's need for rapid heating. Furthermore, continuous idling exacerbates engine wear and exhaust emissions, negatively impacting both the environment and vehicle durability. To address these issues, a parking heater has emerged. As an auxiliary heating device independent of the engine, it provides efficient and rapid heat supply to the cab when the engine is off. The core component of this type of device is the motor assembly, which drives a turbocharger fan and a radiator fan to continuously supply oxygen to the combustion chamber to maintain efficient fuel combustion and to promote heat transfer between the heat exchanger and the cabin air. This design not only significantly improves thermal energy utilization efficiency, but also reduces fuel consumption and operating noise.

[0003] However, existing parking heaters use a separate design for the motor and the volute-type booster fan. This requires complex centering and calibration processes during factory assembly, making it difficult to guarantee assembly accuracy. During long-term operation, vibration can easily cause coaxiality misalignment, affecting the stability of airflow output. Furthermore, the separate structure leads to low heat transfer efficiency and uneven heat dissipation, easily causing localized overheating and reducing motor lifespan. Utility Model Content
