Referring to fig. 1 to 3, fig. 1 and 2 illustrate a structure of a temperature identification tag according to an embodiment of the present invention, and fig. 3 illustrates a structure of a color-changing layer according to an embodiment of the present invention;
the present embodiment provides a temperature identification label 100, the temperature identification label 100 includes a color changing layer 110, a bottom color layer 120, and a heat conducting layer 130, which are sequentially disposed;
the color-changing layer 110 includes a first partition layer 111 coated and formed on the base color layer 120 and a second partition layer 112 coated and formed on the base color layer 120; the first partition layer 111 is used for reversible temperature-sensitive color change when the temperature is lower than a first preset temperature, and the second partition layer 112 is used for irreversible temperature-sensitive color change when the temperature is higher than or equal to the first preset temperature;
the heat conduction layer 130 is used for adhering to the device under test and guiding the heat of the device under test to be transferred to the second partition layer 112;
the first partition layer 111 is made of a reversible temperature sensing material, the second partition layer 112 is made of an irreversible temperature sensing material, and the first partition layer 111 and the second partition layer 112 are arranged at intervals.
It should be noted that, in the present embodiment, first, when the heat conducting layer 130 is disposed, the heat conducting layer 130 may be a heat conducting adhesive, and the regions of the bottom color layer 120 opposite to the second partition layer 112 may be connected to the heat conducting layer 130, that is, the heat conducting layer 130 covers the portions of the second partition layer 112 connected to the bottom color layer 120, so that the heat of the device under test is transferred to the second partition layer 112.
Secondly, when the first partition layer 111 and the second partition layer 112 are provided, the reversible temperature sensing material and the irreversible temperature sensing material are both one of thermochromic pigments, and the difference is that when the temperature of the reversible temperature sensing material forming the first partition layer 111 is lower than a first preset temperature, the thermochromic color is reversible thermochromic, and when the temperature of the irreversible temperature sensing material forming the second partition layer 112 is higher than or equal to the first preset temperature, the thermochromic color is irreversible thermochromic; therefore, the temperature smaller than the first preset temperature may be the ambient temperature, so that when the ambient temperature changes, the temperature sensing discoloration of the first partition layer 111 is observed, and the validity of the temperature identification tag 100 is detected, that is, when the first partition layer 111 can be discolored when the ambient temperature changes, it indicates that the temperature identification tag 100 is valid, and when the second partition layer 112 cannot be discolored when the ambient temperature changes, it indicates that the temperature identification tag 100 is invalid. Similarly, a temperature greater than or equal to the first predetermined temperature refers to a device temperature, and the device temperature is greater than the ambient temperature.
The operating principle of the temperature identification tag 100 is as follows:
referring to fig. 1-3, the temperature identification label 100 includes a color-changing layer 110, a bottom color layer 120, and a heat conductive layer 130; wherein, the color changing layer 110 comprises a first partition layer 111 coated and formed on the base color layer 120 and a second partition layer 112 coated and formed on the base color layer 120; the first partition layer 111 is used for reversible temperature-sensitive color change when the temperature is lower than a first preset temperature, and the second partition layer 112 is used for irreversible temperature-sensitive color change when the temperature is higher than or equal to the first preset temperature; the heat conduction layer 130 is used for adhering to the device under test and guiding the heat of the device under test to be transferred to the second partition layer 112; the first partition layer 111 is made of a reversible temperature sensing material, the second partition layer 112 is made of an irreversible temperature sensing material, and the first partition layer 111 and the second partition layer 112 are arranged at intervals.
Since the first partition layer 111 is coated with the reversible temperature sensing material, the temperature identification tag 100 can detect the effectiveness of temperature sensing of the temperature identification tag 100 through the first partition layer 111, so that the temperature identification tag 100 can be prevented from being failed in temperature sensing; when the heat conduction layer 130 is bonded to the device to be tested, the heat of the device to be tested is transferred to the second partition layer 112 under the action of the heat conduction layer 130, so that the device can be effectively measured by the second partition layer 112 when the first partition layer 111 detects that the temperature identification tag 100 is effective.
Further, in the embodiment, since the light resistance and the heat resistance of the thermochromic pigment are poor, the thermochromic pigment may rapidly fade and lose its color under strong sunlight, and thus, the temperature identification label 100 further includes the ultraviolet film 140 covering the first partition layer 111 and the second partition layer 112, the ultraviolet film 140 can play a role of ultraviolet protection, and can protect the color changing layer 110, so that the stability of the color changing layer 110 can be well protected even under the condition of occasional sunlight exposure, and thus when the temperature identification label 100 is used outdoors, the molecular structure of the color changing layer 110 is not easily damaged, and the useful life and the like of the color changing layer 110 are prolonged.
Further, referring to fig. 1 to 3, in the present embodiment, in the process of measuring the temperature of the device by the second partition layer 112, since the second partition layer 112 is formed by coating the irreversible temperature sensing material on the ground color layer 120, in order to enable the second partition layer 112 to measure different temperatures of the device, the second partition layer 112 at least includes a first measuring portion 113, a second measuring portion 114 and a third measuring portion 115; the first measuring part 113 is used for irreversible temperature-sensitive color change when the temperature is greater than or equal to a first preset temperature; the second measuring part 114 is used for irreversible temperature-sensitive color change when the temperature is greater than or equal to a second preset temperature; the third measuring part 115 is used for irreversible thermochromic color change when the temperature is greater than or equal to a third preset temperature; the first preset temperature is lower than the second preset temperature, and the second preset temperature is lower than the third preset temperature. It should be noted that, in the present embodiment, the first preset temperature is 75 ℃, the second preset temperature is 105 ℃, and the third preset temperature is 120 ℃.
Thus, when the temperature of the device is higher than the first preset temperature and lower than the second preset temperature, or equal to the first preset temperature, the first measuring part 113 performs irreversible thermochromic color change, and the second measuring part 114 and the third measuring part 115 do not change color;
when the temperature of the device is higher than the second preset temperature and lower than the third preset temperature, or equal to the second preset temperature, the first measuring part 113 and the second measuring part 114 perform irreversible thermochromic color change, and the color of the third measuring part 115 is unchanged;
when the temperature of the device is greater than or equal to a third preset temperature, the first measuring unit 113, the second measuring unit 114, and the third measuring unit 115 perform irreversible thermochromic change.
In order to observe the discoloration of the first, second, and third measuring portions 113, 114, and 115, the first, second, and third measuring portions 113, 114, and 115 are disposed at intervals. And the first measuring portion 113, the second measuring portion 114, and the third measuring portion 115 are sequentially disposed in a direction from the first division layer 111 to the second division layer 112. In addition, in order to distinguish the first measuring part 113, the second measuring part 114, and the third measuring part when they change color so as to determine the temperature of the device, the second division layer 112 further includes a first indicating mark, a second indicating mark, and a third indicating mark; the first, second, and third indication marks are used to indicate the first, second, and third measurement units 113, 114, and 115, respectively.
In other embodiments of the present invention, when the first partition layer 111 and the second partition layer 112 are disposed, the first partition layer 111 may also have a circular structure, and the second partition layer 112 may also have an annular structure disposed around the center of the first partition layer 111 and on the outer periphery of the first partition layer 111. The first measuring portion 113, the second measuring portion 114, and the third measuring portion 115 may be arc-shaped segments sequentially arranged at intervals around the center of the first partition layer 111; alternatively, the first measuring portion 113, the second measuring portion 114, and the third measuring portion 115 may be annular portions that are sequentially provided at intervals in the radial direction of the first divided layer 111.
Further, referring to fig. 1 to 3, in order to facilitate determination of the temperature of the device when the first measuring unit 113, the second measuring unit 114, and the third measuring unit are discolored, the colors of the first measuring unit 113, the second measuring unit 114, and the third measuring unit 115 after being discolored with temperature sensing are all different from the color of the ground color layer 120, and the color of the first measuring unit 113 after being discolored with temperature sensing, the color of the second measuring unit 114 after being discolored with temperature sensing, and the color of the third measuring unit 115 after being discolored with temperature sensing are different. It should be noted that, when the temperature is distinguished by color, the temperature of the device can be quickly determined by creating a temperature color chart.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
