Embodiment
[0036] A test method for heater attenuation, based on the above-mentioned heater attenuation test system, comprising the following steps:
[0037] S1. Set a target temperature T m = 110°C, a target holding time t m =20 minutes, then control the heater attenuation test system to start working;
[0038] The target temperature T m The setting range of is 90 to 130°C. In the embodiment, the target temperature is selected as T m =110°C, the target holding time t m The setting range of is 10 to 30 minutes, and in the embodiment, selects and sets the target holding time as t m = 20 minutes.
[0039] S2. After the heater attenuation test system is started, the temperature of the air in the air duct 4 measured by the temperature sensor 5 is T 1 , at T 1 m , the heater 3 starts to work, and the timer starts counting at the same time, and counts until the air in the air outlet pipe 4 is warmed up to T 1 =T m , get the heating time t a ;
[0040] S3. In the following process, by ...

The invention relates to the technical field of heater attenuation test, in particular to an attenuation test system used for a heater as well as a test method. The test system comprises a fan, an airinlet pipe, a heater, an air outlet pipe, a controller, a timing module and a counting module, the fan, the air inlet pipe, the heater and the air outlet pipe are sequentially arranged in an airflowdirection, a temperature sensor is arranged on the air outlet pipe, and the controller is respectively connected with the fan, the heater, the timing module, the counting module and the temperature sensor. The test system continuously performs an attenuation test for multiple times, corresponding number N of times that steps are repeatedly run in each attenuation test as well as heating time ta ofeach attenuation test are recorded until ta is not increased along with increase of N, a corresponding test number N of the attenuation tests is recorded, and an attenuation graph of the heater can be obtained according to the tested data, thereby being significant to improving operation efficiency and application effect of the heater.
Description
technical field [0001] The invention relates to the technical field of heater attenuation testing, in particular to an attenuation testing system and testing method for electric heaters. Background technique [0002] An electric heater refers to an electrical appliance that uses electric energy to achieve a heating effect. It is small in size, high in heating power, and widely used. It adopts intelligent control mode, has high temperature control accuracy, and can be networked with a computer. Wide range of applications, long life and high reliability. The core of the heater principle is energy conversion, the most common is the conversion of electrical energy into heat energy. An electric heater refers to an electrical appliance that uses electric energy to achieve a heating effect. It can be divided into three categories according to the type of heating method: [0003] Electromagnetic heating, electromagnetic heating is to generate an alternating magnetic field through...
