Description

Technical Field

[0001] The utility model mainly relates to the technical field of heater assemblies, in particular to a heater assembly. Background Art

[0002] The heater assembly is a component system in a car used to provide warm air inside the car. It usually works with the vehicle's air-conditioning system to ensure comfort inside the car. It mainly includes a heater core, blower, control damper, air filter and control unit. The blower is used to blow air through the heater core so that the air is heated and then enters the car to achieve the purpose of heating. It usually has different speed settings to adjust the air flow.

[0003] In the currently existing heater assemblies, the heater core is generally installed in the outer shell of the heater assembly. In order to ensure the stability of the heater core, a mounting bracket is usually set up in the outer shell to position the heater core, so that it can better adapt to the environment accompanied by vibration during the driving of the car. However, the mounting bracket will increase the space occupied in the outer shell, thereby reducing the cross-sectional area of ​​the air circulation channel, resulting in increased air flow resistance, which will reduce the efficiency of the blower and reduce the air flow at the same wind speed. Due to the obstruction of air circulation, the heat exchange efficiency between the heater core and the air will be reduced, which means that it will take longer to heat the air. At the same time, it will increase the air resistance to a certain extent, resulting in more noise during operation, especially at high wind speed settings. Utility Model Content
