Abstract
The utility model relates to a thermistor which comprises a thermal substrate made of thermo-sensitive material and an electrode, wherein the top end of the thermal substrate is connected with a heat conducting piece; one end of the heat conducting piece is connected with the thermal substrate, and the other end of the heat conducting piece is connected with thermal medium; the end connected with thermal medium is spherical and is embedded in the thermal substrate; and the heat conducting piece is tungsten material heat conducting piece.
Description
Technical field
The utility model relates to a kind of thermistor, particularly a kind of thermistor that heater is controlled.
Background technology
In the industrial production, usually to use high temperature or K cryogenic treatment technology, need carry out processing at a certain temperature, often to use temperature control equipment, thermistor is a kind of temperature control component commonly used, the resistance value of thermistor can change thereupon variation of temperature, in this way, and the break-make of control circuit accurately.But existing thermistor is generally sheet, for the ceramic material of barium titanate, in use,, then may cause its damage if directly put it in the processing medium, if place it in the medium outside, then can't accurately survey the temperature of medium.
Summary of the invention
The purpose of this utility model is to provide a kind of thermistor at the problem of the existing thermistor existence described in the background technology.
The realization the technical solution of the utility model is as follows:
A kind of thermistor, it comprises temperature-sensitive matrix and electrode that thermo-sensitive material is made, temperature-sensitive matrix top is connected with heat-conducting piece, this heat-conducting piece one end is connected with the temperature-sensitive matrix, the other end connects thermal medium, and an end that is connected with the temperature-sensitive matrix is spherical, and embeds in the temperature-sensitive matrix.
Described heat-conducting piece is the heat-conducting piece that is coated with the tungsten material of insulating barrier.
The beneficial effects of the utility model are connected with heat-conducting piece for the temperature-sensitive matrix top because of thermistor of the present utility model, this heat-conducting piece one end is connected with the temperature-sensitive matrix, the other end connects thermal medium, therefore can be in thermistor with the temperature conduction of thermal medium, make thermistor can sense the variations in temperature of thermal medium, be convenient to the break-make of control heating in time or heat sink.Because the part that heat-conducting piece is connected with the temperature-sensitive matrix is spherical, and be embedded in the temperature-sensitive matrix, therefore, heat-transfer effect is better.Because heat-conducting piece is the heat-conducting piece that is coated with the tungsten material of insulating barrier, and is therefore, more high temperature resistant.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Among the figure, 1 is the temperature-sensitive matrix, and 2 is electrode, and 3 is heat-conducting piece.
Embodiment
With reference to a kind of thermistor shown in Figure 1, it comprises temperature-sensitive matrix 1 and electrode 2 that thermo-sensitive material is made, temperature-sensitive matrix 1 top is connected with heat-conducting piece 3, these heat-conducting piece 3 one ends are connected with temperature-sensitive matrix 1, the other end connects thermal medium, an end that is connected with temperature-sensitive matrix 1 is spherical, and embeds in the temperature-sensitive matrix 1.Described heat-conducting piece 3 is the heat-conducting piece 3 that is coated with the tungsten material of insulating barrier.Because temperature-sensitive matrix 1 top of thermistor of the present utility model is connected with heat-conducting piece 3, these heat-conducting piece 3 one ends are connected with temperature-sensitive matrix 1, the other end connects thermal medium, therefore can be in thermistor with the temperature conduction of thermal medium, make thermistor can sense the variations in temperature of thermal medium, be convenient to the break-make of control heating in time or heat sink.Because the part that heat-conducting piece 3 is connected with temperature-sensitive matrix 1 is spherical, and be embedded in the temperature-sensitive matrix 1, therefore, heat-transfer effect is better.Because heat-conducting piece 3 is the heat-conducting piece 3 that is coated with the tungsten material of insulating barrier, and is therefore, more high temperature resistant.
