Abstract

The invention relates to the technical field of automobile detection, in particular to an automobile conditioner air outlet tightness and ventilation noise testing device, comprising a base, a fan arranged on the base, a fan exhaust duct connected with the fan, and an air flow meter connected with the fan exhaust duct. The fan exhaust duct is connected to an exhaust port connection duct that is connected with a test piece, the exhaust port connection duct is also connected with a micro air pressure meter, and the base is also provided with a power control unit. The fan is provided with a fan intake adjusting valve. The invention is intended to arrive at the precision measurement for air speed of an exhaust port; the precision of air volume may reach 0.01 m<3> / h; both noise and sealing aretested; the tester integration problem is solved. In addition, the test piece is convenient to mount and demount; the requirement for testing tightness and ventilation noise of different types of exhaust ports can be met by adjusting pressure, flow and an air supply connection, the test cost is low, and a fixture has high utilization rate.

Description

technical field [0001] The invention relates to the technical field of automobile detection, and more specifically, relates to a test device for the sealing performance and ventilation noise of an air outlet of an automobile air conditioner. Background technique [0002] With the continuous development of the automobile industry, automobile equipment has entered the era of flexibility, the quality requirements for vehicles are getting higher and higher, and the requirements for the function of the automobile air conditioning system, that is, the comfort, are getting higher and higher. Performance such as noise directly affects user experience. In the entire automobile air conditioning system, the ventilation system of the air conditioner is composed of air ducts and air outlets. The main function is to deliver the treated (temperature adjustment, humidity adjustment, purification) air flow to the cockpit, thereby completing the ventilation in the cockpit. Cooling, heating, ...
