Description

Intelligent temperature-controlled resistor element and electronic device having the same

The present invention relates to an intelligent temperature-controlled resistor element and an electronic device having the intelligent temperature-controlled resistor element, and in particular to an intelligent temperature-controlled resistor element capable of knowing the actual temperature of the resistor element and an electronic device having the intelligent temperature-controlled resistor element.

In the current market, the application of resistor elements is already a very common technology. Current industrial applications require resistor elements that can carry large currents. These resistor elements are coated with aluminum shells to enhance heat dissipation. However, even with the aluminum shell, the heat cannot be completely dissipated quickly, which will cause a temperature difference between the inside and outside of the resistor element. In previous technologies, only the external temperature of the resistor element can be measured to determine whether it is overheated, but the temperature difference between the inside and outside of the resistor element may be as high as 300 degrees Celsius. Users cannot know the true temperature of the resistor element in real time to make adjustments, which can easily cause the inside of the resistor element to burn due to excessive temperature. In the prior art, a resettable temperature fuse or a one-time fuse may be implanted in the resistor. However, the application of both is limited by the specifications of the fuse and cannot be driven and used at will.

Therefore, it is necessary to invent a new intelligent temperature-controlled resistor element and an electronic device having the intelligent temperature-controlled resistor element to solve the deficiencies of the prior art.

One of the main purposes of the present invention is to provide an intelligent temperature-controlled resistor element, which has the effect of knowing the actual temperature of the resistor element.

Another main object of the present invention is to provide an electronic device having the above-mentioned element.

To achieve the above-mentioned purpose, the intelligent temperature-controlled resistor element of the present invention is arranged in an electric circuit in an electronic device, and the electronic device further includes a detection module. The intelligent temperature-controlled resistor element includes an outer shell, a conductive element and a temperature monitoring element. The conductive element is arranged in the outer shell to provide a first resistance value. The temperature monitoring element is disposed in the outer shell, adjacent to the conductive element, and electrically connected to the detection module to provide a second resistance value, wherein the temperature monitoring element is provided with a resistance-temperature variation curve; wherein when the temperature of the conductive element increases due to receiving current, the temperature monitoring element changes the second resistance value of the temperature monitoring element according to the temperature increase; thereby, the detection module detects the second resistance value to obtain the temperature of the conductive element according to the resistance-temperature variation curve.

The electronic device with intelligent temperature-controlled resistor element of the present invention includes an electric circuit, a detection module and an intelligent temperature-controlled resistor element. The detection module is arranged on the electric circuit. The intelligent temperature-controlled resistor element is arranged on the electric circuit. The intelligent temperature-controlled resistor element includes an outer shell, a conductive element and a temperature monitoring element. The conductive element is arranged in the outer shell to provide a first resistance value. The temperature monitoring element is disposed in the outer shell, adjacent to the conductive element, and electrically connected to the detection module to provide a second resistance value, wherein the temperature monitoring element is provided with a resistance-temperature variation curve; wherein when the temperature of the conductive element increases due to receiving current, the temperature monitoring element changes the second resistance value of the temperature monitoring element according to the temperature increase; thereby, the detection module detects the second resistance value to obtain the temperature of the conductive element according to the resistance-temperature variation curve.

In order to enable the Honorable Review Committee to better understand the technical content of the present invention, the preferred specific embodiments are described below.

Please refer to FIG. 1 below, which is a schematic diagram of the appearance of the intelligent temperature-controlled resistor element of the first embodiment of the present invention.

In the first embodiment of the present invention, the intelligent temperature-controlled resistor element 1a includes: a housing 11, a conductive element 21, a temperature monitoring element 31 and an insulating material 41. The housing 11 can be made of aluminum to cover the above-mentioned elements. The conductive element 21 is disposed in the housing 11 to provide a first resistance value. The temperature monitoring element 31 is disposed in the housing 11, adjacent to the conductive element 21, to provide a second resistance value. The temperature monitoring element 31 is a metal with a high temperature coefficient, such as white tungsten, black tungsten, pure nickel, iron alloy, etc., but the present invention is not limited thereto. The conductive element 21 is connected to an external element using two wires 51 and 52 to provide a first resistance value. The temperature monitoring element 31 has two more wires 53 and 54. Therefore, from the appearance of the intelligent temperature-controlled resistor element 1a, the intelligent temperature-controlled resistor element 1a has four wires 51, 52, 53, and 54.

Please refer to FIG. 2 which is a schematic diagram of the exploded view of the intelligent temperature-controlled resistor element of the first embodiment of the present invention and FIG. 3 which is a schematic diagram of the cross-section of the intelligent temperature-controlled resistor element of the first embodiment of the present invention.

In the first embodiment of the present invention, the conductive element 21, the temperature monitoring element 31 and the insulating material 41 are flat. The conductive element 21 may have two conductive plates 21a and a metal wire 21b wrapped around the two conductive plates 21a. The temperature monitoring element 31 is disposed within the clamping range of the two conductive plates 21a, but the present invention does not limit the shape of the conductive element 21. The insulating material 41 is disposed between the temperature monitoring element 31 and the conductive plate 21a and between the conductive plate 21a and the housing 11, respectively. In this first embodiment, the insulating material 41 may be a mica material, but the present invention is not limited to this material. Therefore, it can be seen from FIG. 3 that the cross-section of the intelligent temperature-controlled resistor element 1a is, in order, the outer shell 11, the insulating material 41, the conductive element 21 (i.e., the conductive plate 21a and the metal wire 21b), the insulating material 41, the temperature monitoring element 31, the insulating material 41, the conductive element 21, the insulating material 41 and the outer shell 11.

Please refer to FIG. 4 which is a resistance-temperature variation curve of the intelligent temperature-controlled resistor element of the first embodiment of the present invention.

The temperature monitoring element 31 is provided with a resistance-temperature variation curve. When the temperature of the temperature monitoring element 31 increases, the second resistance of the temperature monitoring element 31 will also change, and the second resistance is proportional to the temperature, so that the resistance-temperature variation curve can be measured. The second resistance is different from the first resistance of the conductive element 21. Therefore, when the temperature of the conductive element 21 increases due to receiving current, the temperature of the temperature monitoring element 31 is bound to increase at the same time because the temperature monitoring element 31 is in contact with or adjacent to the conductive element 21. In this way, the temperature of the conductive element 21 can be known from the resistance of the temperature monitoring element 31.

Next, please refer to FIG. 5 which is a schematic diagram of the appearance of the intelligent temperature-controlled resistor element of the second embodiment of the present invention and FIG. 6 which is a schematic diagram of the assembly of the intelligent temperature-controlled resistor element of the second embodiment of the present invention.

In the second embodiment of the present invention, the outer shell 12 of the intelligent temperature-controlled resistor element 1b is a square or rectangular parallelepiped, and its size is to accommodate the conductive element 22, the temperature monitoring element 32 and the insulating material 42 therein. The conductive element 22 is wound in a spiral shape, and the temperature monitoring element 32 is cylindrical, so that the temperature monitoring element 32 is arranged within the surrounding range of the conductive element 22. In the second embodiment of the present invention, there are also four wires 51, 52, 53, and 54. The insulating material 42 is in a sheet shape to isolate the conductive element 22 from the outer shell 12. In this second embodiment, the insulating material 42 can also be a mica material, but the present invention is not limited to this material. Finally, the above components are placed in the square outer shell 12.

Please refer to FIG. 7 which is a schematic diagram of the assembly of the intelligent temperature-controlled resistor element of the third embodiment of the present invention.

In the third embodiment of the present invention, the appearance of the housing 12 of the intelligent temperature-controlled resistor element 1c and its conductive element 22 and temperature monitoring element 32 are the same as those of the second embodiment, but the insulating material 43 may be a hollow cylinder to cover the conductive element 22 to isolate the conductive element 22 from the housing 12. In this third embodiment, the insulating material 43 may be a ceramic material, but the present invention is not limited to this material.

Please refer to FIG. 8 which is a schematic diagram of the assembly of the intelligent temperature-controlled resistor element of the fourth embodiment of the present invention.

In the fourth embodiment of the present invention, the appearance of the housing 12 of the intelligent temperature-controlled resistor element 1d and its conductive element 22 and temperature monitoring element 32 are the same as those of the second embodiment, but a double-layer insulation design is adopted, and the first layer of insulating material 43 can be a hollow cylinder to cover the conductive element 22, and a second layer of sheet-shaped insulating material 42 is added to isolate the conductive element 22 from the housing 12. In this fourth embodiment, the insulating material 43 can be a ceramic material, and the insulating material 42 can be a mica material, but the present invention is not limited to the above materials.

Finally, please refer to FIG. 9 which is a schematic diagram of an electronic device with an intelligent temperature-controlled resistor element of the present invention.

The intelligent temperature-controlled resistor element 1a can be arranged on the electrical loop C in the electronic device 2 to connect other electronic components 3, and is electrically connected to the detection module 4 via two wires 53 and 54. The electronic component 3 can be any active or passive component, and the present invention does not limit the type of the electronic component 3. The detection module 4 can be a hardware, a software combined with hardware, or a firmware combined with hardware. For example, it can be constructed in a chip, but the present invention is not limited to this. The detection module 4 detects the second resistance value of the temperature monitoring element 31, and the temperature of the temperature monitoring element 31 can be obtained according to the resistance-temperature change curve of the temperature monitoring element 31, and the temperature of the conductive element 21 adjacent to the temperature monitoring element 31 can be inferred. If the temperature is too high, the detection module 4 can stop the electronic component 3 in the electronic device 2 from operating or reduce the operating performance to cool down the conductive component 21 and avoid burning.

In addition to the above-mentioned components, the smart temperature-controlled resistor components 1a, 1b, 1c, and 1d of the electronic device 2 of the present invention can also be connected to other components. Since the technology of other components is not the focus of the present invention, they will not be described here. In addition, the present invention is not limited to the implementation of the above-mentioned smart temperature-controlled resistor components 1a, 1b, 1c, and 1d.

From the above description, it can be seen that the intelligent temperature-controlled resistor elements 1a, 1b, 1c, 1d of the present invention can conveniently let the detection module 4 know the true temperature of the internal conductive elements 21, 22, so as to avoid the conductive elements 21, 22 being unaware of the excessively high temperature, thus effectively solving the defects of the prior art.

It should be noted that the above-mentioned embodiments are only examples of the preferred embodiments of the present invention. To avoid redundant description, not all possible variations and combinations are described in detail. However, those with ordinary knowledge in the field should understand that the above-mentioned modules or components may not be necessary. In addition, other more detailed known modules or components may also be included in order to implement the present invention. Each module or component may be omitted or modified as required, and there may not be other modules or components between any two modules. As long as it does not deviate from the basic structure of the present invention, it should be within the scope of the rights claimed by this patent, and the scope of the patent application should prevail.
