The application relates to the technical field of
automobile air conditioning systems, and discloses a temperature compensation device for an automobile air conditioner speed regulating
resistor, which comprises a temperature compensation module, a speed regulating
resistor module and a support
assembly. The temperature compensation device for the automobile air conditioner speed regulating
resistor is characterized in that the lead of the
thermistor is vertically welded with the compensation circuit board, the
constant pressure exerted by the elastic pressing piece in the connecting support is combined, the
thermistor is ensured to be in zero-gap contact with the automobile air conditioner speed regulating resistor body, accurate compensation in the whole temperature range is realized, the stability of the fan rotating speed is improved, the connecting support integrates the compensation circuit board and the spring-driven clamping rod structure, the number of parts is reduced compared with a traditional scheme, the heat-conducting sheet is directly connected with the heat-dissipating sheet to replace the external heat-dissipating circuit, the
external circuit design is reduced, the specific surface area can be increased through the
honeycomb holes, the
natural convection efficiency is improved through the micro-arc oxidation layer, the heat-dissipating effect is optimized, and the
system complexity is reduced.
