Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The utility model temperature sensor embodiment comprises: temperature sensor body and have the heat conductive insulating shell of a plane surface at least.
The said temperature sensor body can specifically be a thermal sensing element, for example the element made from fusible alloy or temperature-sensitive insulating material, bimetallic strip, thermopair, thermistor, semiconductor material etc.The physical property of these materials varies with temperature and changes.
With the thermistor is that example describes, thermistor is that resistance value varies with temperature and the sensitive element that changes, comprise: positive temperature coefficient (PTC) (Positive Temperature Coefficient, PTC) thermistor and negative temperature coefficient (Negative Temperature Coefficient, NTC) thermistor.In operating temperature range, resistance value rises with temperature, and what increase is PTC themistor; Resistance value rises with temperature, and what reduce is NTC themistor.
Its principle of work is: under the situation of extraneous power supply power supply, the resistance of thermistor changes with variation of temperature, and the current value of its output just changes with changes in resistance.Temperature variant current value sends to analog-to-digital conversion module through signal transmssion line.Above-mentioned analog-to-digital conversion module converts current analog signal to represent Temperature numerical digital signal, promptly realizes the temperature survey function.
Among the utility model temperature sensor embodiment, above-mentioned heat conductive insulating shell is used for the encapsulation temperature sensor body, comprises a plane surface in its structure at least.
This is because the utility model temperature sensor is used to measure the temperature of solar panel, and cell panel is made generally in tabular in order to increase the area that receives solar radiation.During the temperature on temperature sensor measurement solar panel surface, need be fitted in the surface or the back side of solar panel, the contact area of itself and solar panel is big more, can accurately measure the temperature of solar panel more.And the temperature sensor that prior art adopts is generally the cylindrical temperature sensor probe of selling on the present market, because this cylindrical probe and solar panel are fixedly the time, contact area is very little, approximate line style, thereby, the sensitivity of existing temperature sensor probe sense temperature is not high, and yet out of true of measured value.
For these reasons, the solar panel that the utility model provides temperature sensor embodiment, the heat conductive insulating shell that will be used for the encapsulation temperature sensor body is arranged to have at least the shape of a plane surface.When reality is used, this plane surface and solar panel are fit together, can increase the contact area of temperature sensor and cell panel, improve the sensitivity of temperature sensor body perception solar panel surface temperature.
In addition, in another embodiment of the utility model temperature sensor, between heat conductive insulating shell and temperature sensor body, fill the good Heat Conduction Material of heat conductivility, for example epoxy resin Heat Conduction Material, organosilicon Heat Conduction Material etc. are so that firm temperature sensor body is in the position of heat conductive insulating enclosure.On the other hand; owing to the temperature sensor body is generally smaller, relatively more fragile element; be subjected to ectocine as applying factors such as external force and damage easily; in the present embodiment, the Heat Conduction Material that is filled in the heat conductive insulating enclosure also has protection temperature sensor body and avoids the extraneous effect that damages.
With reference to Fig. 2, show the structural representation of the utility model temperature sensor embodiment one, comprising: temperature sensor body 11, heat conductive insulating shell 21 and signal transmssion line 3.Wherein:
Heat conductive insulating shell 21 is the prolate cube structure, is used for encapsulation temperature sensor body 11.
In actual the use, a surface of prolate side's build heat conductive insulating shell 21 of temperature sensor is fitted to the surface or the back side of solar panel, can accurately measure the temperature on solar panel surface.
Fig. 3 shows the structural representation of the utility model temperature sensor embodiment two, comprising: temperature sensor body 11, heat conductive insulating shell 22 and signal transmssion line 3.Wherein:
Heat conductive insulating shell 22 is the oblate body shape, is used for encapsulation temperature sensor body 1.
As shown in Figure 3, the structure of this oblate body shape shell is specially: upper and lower surface is the cylindrical structure on circular table plane, and inside is hollow structure.Cylindrical height can be very little, helps heat conduction like this.
During actual the use, a circular table plane of the oblate body shape heat conductive insulating shell 22 of temperature sensor is fitted to the surface or the back side of solar panel, can accurately measure the temperature on solar panel surface.
It more than is description to temperature sensor embodiment with difformity heat conductive insulating shell, need to prove, the shape of heat conductive insulating shell does not limit above two types, can make different shapes according to actual needs, as long as the surface of contact of assurance and solar panel is the plane.In addition, among the above-mentioned two temperatures sensor embodiment, in the housing, the residual cavity part can be filled the good Heat Conduction Material of heat conductivility behind the built-in temperature sensor body.
In a word, the temperature sensor that the utility model embodiment provides, be mainly used in the temperature of measuring solar panel in the solar power system, adopt the heat conductive insulating shell that has a plane surface at least to come the encapsulation temperature sensor body, when temperature sensor is fixed in solar panel, fitting in plane and plane, makes the fixing easier of temperature sensor.In addition, adopt this structure, the contact area of temperature sensor and cell panel is bigger, the temperature on perception solar panel surface more delicately, it is more accurate that temperature data is measured, and then guarantee that the staff understands the influence of the surface temperature of solar panel to solar electrical energy generation more exactly, promote the development and use of sun power.
Further; the preferred embodiment of the utility model temperature sensor; between temperature sensor body and heat conductive insulating shell, be filled with the good Heat Conduction Material of heat conductivility; not only can the equilibrium temperature sensor body in the position of heat conductive insulating enclosure, can also protect the temperature sensor body to avoid ectocine and damage.
Each embodiment in this instructions all adopts the mode of going forward one by one to describe, and what each embodiment stressed all is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
More than to a kind of solar panel temperature sensor provided by the utility model, be described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
