本发明公开了一种应用于新能源汽车的NTC温度传感器及系统,涉及温度传感器技术领域,一种应用于新能源汽车的NTC温度传感器,包括外壳和设置于所述外壳中的NTC半导体,还包括:使所述外壳外部的流体介质中的热量传导至位于所述外壳内NTC半导体上的导流簧;本发明通过设置导流簧填充在外壳中,一方面导流簧能够与外壳内壁紧贴,另一方面可以对NTC半导体具有包裹作用,即提高了热响应时间速度,又方便NTC半导体的安装,并通过导流簧与外壳之间形成若干个大、小腔室,通过大、小腔室的设置,能够使外壳外流体介质穿过外壳,与外壳内的NTC半导体相邻近,进一步有效的提高了导热效率、并缩短了NTC半导体热响应时间。

    The invention discloses an NTC temperature sensor and system applied to a new energy automobile, and relates to the technical field of temperature sensors, and the NTC temperature sensor applied to the new energy automobile comprises a housing and an NTC semiconductor arranged in the housing. The flow guide spring is used for conducting heat in a fluid medium outside the shell to the NTC semiconductor in the shell; the shell is filled with the flow guide spring, on one hand, the flow guide spring can be tightly attached to the inner wall of the shell, on the other hand, the NTC semiconductor can be wrapped, the thermal response time and speed are increased, installation of the NTC semiconductor is facilitated, the multiple large cavities and the multiple small cavities are formed between the flow guide spring and the shell, and through arrangement of the large cavities and the small cavities, the thermal response speed of the NTC semiconductor is improved. And a fluid medium outside the shell can penetrate through the shell to be adjacent to the NTC semiconductor in the shell, so that the heat conduction efficiency is further effectively improved, and the thermal response time of the NTC semiconductor is shortened.
