Abstract
The utility model discloses an evaporator temperature sensor, which comprises a connector, a lead, a sleeve pipe, a fixing clamp, and a temperature-sensitive head. The temperature sensor further comprises an aluminum casing. The temperature-sensitive head is packaged inside the aluminum casing through resin. The temperature-sensitive head is packaged inside the aluminum casing through resin. The aluminum casing is characterized by good heat transfer, processing convenience and relatively low cost. After being packaged inside the aluminum casing, the temperature-sensitive head is inserted into the core of an evaporator and directly contacts mediums. The temperature-sensitive head enables rapid reaction and only spends three seconds in reacting in the same mediums. The evaporator temperature sensor can rapidly reflect the current temperature of the evaporator surface. Furthermore, the evaporator temperature sensor has the advantages of sensitive control and convenient installation.
Description
Technical field
The utility model relates to the automobile air conditioning technology field, particularly a kind of evaporator temperature sensor.
Background technology
In air conditioning for automobiles, evaporator temperature sensor is the thermistor (temperature is more high, and resistance is more little) of negative temperature coefficient, and its resistance changes along with the evaporator surface variation of temperature.In the process of compressor operating, panel/ECU periodically pick-up transducers resistance and relatively after judge, the start and stop of control compressor, the frosting of device surface avoids evaporating.
For preventing frosting effectively, the reactivity of temperature sensor should be sensitive.The mounting means of traditional evaporator temperature sensor is to be suspended in evaporator surface, and temperature-sensitive head is with epoxy resin enclosed.The reaction time of the evaporator temperature sensor of this kind state is longer, generally at 15s, and the Current Temperatures on reactive evaporation device surface truly, it is more serious to lag behind.
The utility model content
Technical problem to be solved in the utility model is at the deficiencies in the prior art, to provide a kind of evaporator temperature sensor that improves the reaction time of sensor significantly.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of evaporator temperature sensor, comprise connector, lead, sleeve pipe, fixing card, temperature-sensitive head, described temperature sensor also comprises aluminum hull, described temperature-sensitive head by resin-encapsulated in aluminum hull.
Described sleeve pipe is connected with connector by lead.
The utility model adopts said structure, have the following advantages: 1, temperature-sensitive head is potted in by resin that (heat of aluminum hull is transmitted in the aluminum hull, easy to process, and cost is lower), insert evaporator core, directly contact with " medium ", the reaction time is fast, and measuring its reaction time in same media is 3s; 2, the current temperature in reactive evaporation device surface soon, control is sensitive, and is easy for installation.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is structural representation of the present utility model;
In Fig. 1,1, connector; 2, lead; 3, sleeve pipe; 4, fixing card; 5, aluminum hull.
Embodiment
A kind of evaporator temperature sensor as shown in Figure 1 comprises connector 1, lead 2, sleeve pipe 3, fixing card 4, temperature-sensitive head, and temperature sensor also comprises aluminum hull 5, described temperature-sensitive head by resin-encapsulated in aluminum hull 5.
By reference to the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
