Abstract

The invention discloses a temperature limiter service life testing device, relates to the technical field of air conditioner part detection, and solves the problem that in the prior art, an electric hair drier is used for testing the service life of a temperature limiter, so that a testing result is unstable. The device comprises a heating assembly, a heat dissipation assembly, a test carrier anda first air duct, a to-be-tested temperature limiter is installed on the test carrier located above an air outlet of the first air duct, the heating assembly and the heat dissipation assembly are located at the two ends of the first air duct, and hot air generated by heating of the heating assembly flows out through the air outlet of the first air duct and heats the to-be-tested temperature limiter. The heat dissipation assembly introduces outside normal-temperature air into the first air channel and the air flows out of the air outlet to cool the to-be-tested temperature limiter, so that therequired temperature is provided for the opening and closing of the to-be-tested temperature limiter contact through the heating assembly and the heat dissipation assembly, and the service life of theto-be-tested temperature limiter is measured by recording the opening and / or closing times of the to-be-tested temperature limiter contact. The service life result of the temperature limiter measuredby the device is good in stability.

Description

technical field [0001] The invention relates to the technical field of air conditioner component detection, in particular to a temperature limiter life testing device. Background technique [0002] The temperature limiter is a temperature sensitive controller, mainly including temperature sensing parts and contacts. Under normal conditions, the contacts are closed, and the corresponding circuit works normally; when the temperature sensed by the temperature-sensing component exceeds the set range (lower or higher than a certain temperature value), the contacts are disconnected, causing the corresponding circuit to be disconnected. Open; when the temperature returns to the set range, the contacts are closed again, and the corresponding circuit is also closed again. Therefore, the temperature limiter can limit the corresponding temperature within the set range and play a protective role. [0003] Air-conditioning motors and electric heating components are strong electric devi...
