Sensitivity test equipment for automobile thermostat

Abstract

The invention relates to the technical field of thermostat detection, and provides an automobile thermostat sensitivity test device, the automobile thermostat is provided with a connecting end and a large and small circulation output end, the automobile thermostat sensitivity test device comprises a rack with a liquid storage space, and a temperature control part, an extraction part and a detection part which are arranged on the rack; the temperature control part is positioned in the liquid storage space and below the liquid storage space; the extraction part is located in the liquid storage space and communicates with the connecting end; and the detection part is respectively communicated with the large and small circulation output ends. The temperature control part controls the temperature of the cooling liquid, the extraction part sends the cooling liquid to the automobile thermostat, the automobile thermostat sends the cooling liquid to the detection part through the large and small circulation output ends, the detection part detects the flow velocity difference of the large and small circulation output ends, and the sensitivity of the automobile thermostat to the temperature is determined through the flow velocity difference and the corresponding temperature. According to the automobile thermostat sensitivity test equipment provided by the invention, the sensitivity of the automobile thermostat can be accurately detected under the condition of relatively low cost.
