Abstract
The utility model relates to a temperature sensor for liquid heater. The heat-conducting thermal-insulation type thermal-insulation packaging box comprises a shell (5), an insulation plate (4), a heat-conducting medium (3), a thermistor (2) and an embedding object (1), wherein the heat-conducting medium (3) is arranged on the lower portion of an inner cavity of the shell (5), the thermistor (2) is arranged in the heat-conducting medium (3), the insulation plate (4) is arranged on the top surface of the heat-conducting medium (3), and the embedding object (1) is encapsulated on the top surface of the insulation plate (4). The utility model discloses because the contact surface between insulation board and the shell combines through interference fit to adorn thermistor and heat-conducting medium below the insulation board firmly in the inner chamber of shell, in addition, the embedment above the insulation board can firmly fix the position of insulation board. The utility model provides a thermistor is because it is the heat-conducting medium around, consequently, its temperature variation that can be to the metal casing surface makes the sensing rapidly, and the temperature of sensing also can dwindle greatly with actual temperature's deviation moreover, has improved the sensitivity and the accuracy of product, has shortened induction time.
Description
1, technical field:
The utility model is a kind of temperature sensor that is used for liquid heater, belongs to the improvement technology of temperature sensor.
2, background technology:
In the present commercially available liquid heater, the temperature sensor of band thermistor that uses generally adopts by embedding thing 1 the packaged type structure of thermistor 2 direct embeddings in shell 5, its structural representation as shown in Figure 1, the variation sensing time of this kind sensor for temperature is long, and sensed temperature is relatively large with the deviation of actual temperature, influences the degree of accuracy and the test duration of product test.
3, summary of the invention:
The purpose of this utility model is to overcome above-mentioned shortcoming and provides a kind of fast to the variation of temperature sensitive time, accurately the temperature sensor that is used for liquid heater of sensing liquid heater actual temperature.
Structural representation of the present utility model as shown in Figure 2, include shell (5), insulcrete (4), heat-conducting medium (3), thermistor (2), embedding thing (1), heat-conducting medium (3) is equipped with in the inner chamber bottom of shell (5), thermistor (2) places in the heat-conducting medium (3), insulcrete (4) is installed in the end face of heat-conducting medium (3), and embedding thing (1) is encapsulated in the end face of insulcrete (4).
Above-mentioned insulcrete (4) is sleeved on the inner chamber of shell (5) by the interference fit between the inwall of its periphery and shell (5).
Above-mentioned thermistor (2) places the middle part of heat-conducting medium (3).
The cross sectional shape of above-mentioned shell (5) can be made ovalize, circle and rule or irregular bent limit shape, or make be rectangle, square and regular or irregular polygon.
Above-mentioned shell (5) is made by Heat Conduction Material, and insulcrete (4) is a cardboard, and heat-conducting medium (3) is a heat-conducting silicone grease, and embedding thing (1) is an epoxy resin.
The utility model since insulcrete combine by interference fit with surface of contact between the shell, thereby the inner chamber that the thermistor below the insulcrete and heat-conducting medium firmly are contained in shell, in addition, the embedding thing above the insulcrete can firmly fix the position of insulcrete.Thermistor in the utility model is owing to be heat-conducting medium around it, therefore, it can make sensing rapidly to the metal shell surface temperature change, and sensed temperature is also dwindled greatly with the deviation of actual temperature, improve the sensitivity and the degree of accuracy of product, shortened the sensitive time.The utility model is that a kind of design is ingenious, simple in structure, the convenient and practical temperature sensor that is used for liquid heater.

Fig. 1 is the structural representation of existing temperature sensor;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the A-A sectional view among Fig. 2;
Fig. 4 is installed in structural representation in the well heater for the utility model.
5, specific embodiments:
Embodiment:
Structural representation of the present utility model is shown in Fig. 2,3, include shell 5, insulcrete 4, heat-conducting medium 3, thermistor 2, embedding thing 1, heat-conducting medium 3 is equipped with in the inner chamber bottom of shell 5, thermistor 2 places in the heat-conducting medium 3, insulcrete 4 is installed in the end face of heat-conducting medium 3, and embedding thing 1 is encapsulated in the end face of insulcrete 4.
In the present embodiment, above-mentioned insulcrete 4 is sleeved on the inner chamber of shell 5 by the interference fit between the inwall of its periphery and shell 5.Guarantee that by interference fit embedding thing 1 can not flow to around the thermistor 2 adding man-hour between insulcrete 4 and the shell 5.
For further guaranteeing the actual temperature of accurate sensing liquid heater, above-mentioned thermistor 2 places the middle part of heat-conducting medium 3.
The cross sectional shape of above-mentioned shell 5 can be made ovalize, circle and rule or irregular bent limit shape, or make be rectangle, square and regular or irregular polygon.In the present embodiment, be convenient processing and installation, the cross sectional shape of above-mentioned shell 5 can be made rounded.
Above-mentioned shell 5 is made by Heat Conduction Material, and insulcrete 4 is a cardboard, and heat-conducting medium 3 is a heat-conducting silicone grease, and embedding thing 1 is an epoxy resin.In the present embodiment, shell 5 by heat conductivility preferably aluminium make.
The utility model be installed in the well heater structural representation as shown in Figure 4, the utility model assembly B is installed in well heater inner bag 6 bottoms near on the position of heat-generating pipe 8 by support 7.
