Abstract

The present invention discloses a testing device and method for air-heating PTC products. The testing device for air-heating PTC products includes an air duct, a fan, an inlet temperature detection component, an outlet wind speed detection component, an outlet temperature detection component and an adjustment mechanism; the fan is arranged in the air duct, and the air duct has a placement area for placing the air-heating PTC product to be tested; the air duct has an inlet and an outlet, the inlet temperature detection component is arranged on the air duct between the placement area and the inlet, and the inlet temperature detection component is used to detect the inlet temperature; the outlet wind speed detection component and the outlet temperature detection component are arranged on the air duct between the placement area and the outlet, the outlet wind speed detection component is used to detect the outlet wind speed, and the outlet temperature detection component is used to detect the outlet temperature; the adjustment mechanism is used to adjust the cross-sectional area of ​​the air duct. By adopting the above scheme, the beneficial effect of being able to simultaneously meet the test of air-heating PTC products with different structures and different heat dissipation areas on the same testing device is achieved.
