Description

Technical Field

[0001] The invention belongs to the technical field of protection devices, and in particular relates to an adaptive temperature regulating protection device. Background Art

[0002] In modern industry, temperature fluctuations pose a significant challenge to the performance and safety of hardware systems. During operation, heating components often generate significant heat. If heat is not dissipated promptly, it can lead to system overheating, damage to critical components, and even safety incidents.

[0003] Traditional circuit breaker protection circuits rely primarily on temperature sensors and electronic thermostats, measuring temperature and disconnecting the circuit when it's too high. However, these feedback systems are complex and overly reliant on electronic components, making them susceptible to electromagnetic interference, which can lead to misjudgments or malfunctions. Their reliability and stability are significantly reduced, especially in harsh environments. If a sensor or thermostat fails, the equipment loses its temperature protection and will operate at extreme temperatures. This can lead to equipment overload and shutdown, or even burnout and breakdown, potentially causing significant personal and financial losses. Therefore, the development of a more direct and reliable temperature regulation and protection device has become an urgent need for practitioners. Summary of the Invention

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0033] Example 1

[0034] To solve the technical problems in the background art, the following self-adaptive temperature regulation protection device is given:

[0035] In combination with Figures 1-2 As shown in the figure, a self-adaptive temperature regulation protection device, the device comprises:

[0036] a base plate 1;

[0037] a heating element 11, which is attached to the front surface of the base plate 1;

[0038] a heat conduction fin 2, which is vertically erected on the top of the heating element 11;

[0039] a thermal bimetal 3, which is a inverted L-shaped spring structure, the vertical part is attached to one side of the bottom of the heat conduction fin 2, and the insulated contact 311 is arranged on the bottom surface of the end of the horizontal part; the thermal bimetal 3 can be deformed by the heat conducted by the heat conduction fin 2, so that the end of the horizontal part is bent downward;

[0040] a main power switch 4, which includes an L-shaped power supply support 41 arranged below the thermal bimetal 3, the outer surface of the power supply support 41 is provided with a main power positive spring 42 and a main power negative spring 43 arranged side by side above and below, respectively, the end of the main power negative spring 43 is provided with a conductive ring 432 which internally axially sleeves a protection contact 431, the conductive ring 432 passes through a U-shaped notch opened at the end of the main power positive spring 42, and is coaxially opposite to the insulated contact 311;

[0041] The total power switch 4 is divided into a normal state and an emergency stop state. When in the normal state, the total power positive spring 42 is tightly attached to the conductive ring 432 on the total power negative spring 43, forming an effective power supply circuit to ensure that the total power supply is connected in real time to control the start and stop of the heating element 11. When in the emergency stop state, the thermal bimetallic strip 3 is heated and bent downward, causing the insulating contact 311 below it to abut against the protection contact 431, and the conductive ring 432 is disconnected from the total power positive spring 42, completing the instantaneous circuit breaking of the power supply circuit, and the total power supply is turned off in real time.

[0042] The guide column 55 includes an insulating isolation guide sleeve 553 vertically embedded in the end of the lateral part of the contact support 51, and a guide rod 554 is slidably connected in the insulating isolation guide sleeve 553. The bottom end of the guide rod 554 is axially connected with a ceramic contact 551, and the ceramic contact 551 is elastically abutted with the upper contact 321 of the thermal bimetallic strip 3 through a reset spring 552 axially sleeved on the lower part of the guide rod 554. The upper part of the guide rod 554 is circumferentially provided with a sliding variable resistor 555, and the upper and lower ends of the sliding variable resistor 555 are respectively provided with the heat dissipation negative electrode 56 and the heating negative electrode 57.

[0043] Through the above technical means, the design of the self-adaptive temperature regulation protection device has a significant protection circuit effect, which brings reliable protection to industrial equipment and electronic systems. First, the device uses a thermal bimetallic strip 3 as a trigger component, which has unique physical properties that allow it to adjust the bending degree according to the temperature changes conducted by the heating element 11 (CPU, etc.) on the substrate 1 (circuit board). When the temperature exceeds the preset value, the thermal bimetallic strip 3 bends downward at the end, causing the insulating contact 311 to contact the protection contact 431, until the insulating contact 311 abuts against the conductive ring 432 of the protection contact 431, which moves downward and is disconnected from the total power positive spring 42, thereby triggering the total power switch 4 to enter the circuit breaking protection state immediately. This immediate feedback process ensures that the equipment can be powered off immediately when the temperature abnormally rises, effectively avoiding the risk of equipment damage due to overheating, protecting the safety of the equipment and personnel. Second, compared with traditional electronic temperature control systems, this mechanical circuit breaking protection design greatly simplifies the structural design of the system and the cost of later maintenance; and the mechanical action of the thermal bimetallic strip 3 as the main trigger component is reliable and durable, reducing the risk of downtime caused by overload breakdown of electronic components, and is not affected by electromagnetic interference, improving the stability of long-term use of the equipment and the universality in harsh environments, effectively ensuring the safe operation and continuous output of the equipment.

[0044] As a preferred technical solution, the heat-conducting fin 2 is an open upward fin structure, which increases the unit ventilation area and improves the cooling effect.

[0045] Embodiment Two

[0046] As Figures 1-6 shown, on the basis of the above embodiment, the present embodiment further gives the following content:

[0047] In the present embodiment, the hot bimetallic strip 3 is provided with a movable contact 5, which is bidirectional linkage control with the hot bimetallic strip 3 to set the heat dissipation fan and heating film to the heating element 11 to complete the auxiliary heat dissipation or heating of the heating element 11;

[0048] The movable contact 5 includes a vertical L-shaped contact bracket 51 vertically arranged on the front surface of the substrate 1, and a guide column 55 vertically slidingly arranged at the end of the horizontal part of the contact bracket 51, which is insulated from the contact surface; the hot bimetallic strip 3 is provided with an upper contact 321 coaxially arranged with the insulated contact 311 at the top surface of the horizontal part of the hot bimetallic strip 3; the bottom end of the guide column 55 is coaxially and elastically insulated from the upper contact 321; the upper and lower parts of the guide column 55 are respectively provided with a heating negative electrode 57 and a heat dissipation negative electrode 56; the inner side of the guide column 55 is respectively provided with a heating positive electrode 53 and a heat dissipation positive electrode 54;

[0049] The guide column 55 is divided into heat dissipation adjustment state and heating adjustment state; in the heat dissipation adjustment state, the hot bimetallic strip 3 is heated and deformed downward, and drives the guide column 55 to move downward, so that the heating negative electrode 57 and the heat dissipation positive electrode 54 are electrically connected to form an effective power supply circuit, and the heat dissipation fan is started to dissipate heat from the heating element 11; in the heating adjustment state, the hot bimetallic strip 3 is cooled and deformed upward, and drives the guide column 55 to move upward, so that the heating negative electrode 57 and the heating positive electrode 53 are electrically connected to form an effective power supply circuit, and the heating film is started to heat the heating element 11.

[0050] By the above technical means, first of all, the device utilizes the thermal sensitive bending characteristics of the thermal bimetallic strip 3, and through the movable contact 5 arranged on one side, it cleverly realizes the time-sharing and different step starting and stopping of the cooling fan and the heating film. Specifically, when the device temperature rises, the thermal bimetallic strip 3 is heated and bends downward, driving the guide column 55 to move downward, triggering the conductive connection between the cooling negative electrode 56 and the cooling positive electrode 54, and starting the cooling fan. This structural design effectively utilizes the fan to assist in cooling the heating element 11, preventing overheating of the device, thereby protecting the normal operation of the device and prolonging the service life; on the contrary, when the device temperature drops to a lower level (outdoor cold start needs preheating), the thermal bimetallic strip 3 is cooled and bends upward, driving the guide column 55 to move upward, triggering the conductive connection between the heating negative electrode 57 and the heating positive electrode 53, and starting the heating film. This structural design can quickly raise the temperature of the heating element 11, ensuring that the device can still operate efficiently in a low temperature environment. This instant feedback adjustment function not only quickly responds to changes in environmental temperature, but also ensures that the heating element 11 is always within the appropriate operating temperature range, improving the performance stability and reliability of the device.

[0051] Secondly, the structural design of the movable contact 5 makes the device have good mechanical stability and response speed during operation. The vertical arrangement of the inverted L-shaped contact bracket 51 and the cooperation with the guide column 55 ensure that the contact can instantaneously feedback when the thermal bimetallic strip 3 deforms, and the insulating isolation guide sleeve 553 and the ceramic contact 551 of the guide column 55 further enhance the contact reliability and safety of the contact and the thermal bimetallic strip 3. This delicate mechanical structure design not only improves the service life of the device, but also reduces the risk of failure caused by mechanical wear, ensuring the reliability and accuracy of temperature regulation.

[0052] In addition, the sliding variable resistor wire 555 on the guide column 55 design (similar to a sliding variable resistor) enhances the accuracy and flexibility of temperature regulation. Preferably, the sliding variable resistor wire 555 is a copper wire; the upper and lower ends of the sliding variable resistor wire 555 are respectively provided with the cooling negative electrode 56 and the heating negative electrode 57, and the movement of the guide column 55 changes the conductive loop, thereby accurately controlling the switching of the cooling and heating functions. This design not only enables the device to automatically adjust the temperature control mode according to different environmental requirements, but also enables the device to maintain stable use in complex and harsh environments, reducing human intervention while reducing operation complexity and maintenance cost.

[0053] In summary, this self-adaptive temperature regulation protection device realizes intelligent adjustment of the device temperature through the clever cooperation of the thermal bimetallic strip 3 and the movable contact 5. Its automatic cooling and heating functions ensure the stable operation of the device under various environmental conditions, significantly improving the reliability and service life of the device.

[0054] Example Three

[0055] As Figure 1 And Figures 4-6 As shown in the above embodiments, the present embodiment further provides the following content:

[0056] The contact support 51 is vertically provided with a contact track 52 of insulating material inside the top surface of the lateral part, a vertical through slot 521 is formed in the middle of the contact track 52, and the heating positive pole 53 and the heat dissipation positive pole 54 are respectively embedded in the through slot 521 in opposite positions.

[0057] The heating positive pole 53 and the heat dissipation positive pole 54 are both round head conductive column structures, and are detachably connected to the through slot 521 through bolts at their tail ends.

[0058] The ceramic contact 551, the insulating contact 311, the upper contact 321, and the protection contact 431 are all round head insulating column structures.

[0059] The guide rod 554 is a hollow ceramic cylindrical structure.

[0060] Through the above technical means, first, the contact track 52 of insulating material provided inside the top surface of the lateral part of the contact support 51 provides superior electrical insulation protection for the movable contact 5. The heating positive pole 53 and the heat dissipation positive pole 54 are embedded in the vertical through slot 521 in the middle of the contact track 52, and are detachably connected to the through slot 521 through bolts at their tail ends. This design not only ensures the effective isolation between the conductive parts and prevents electrical short circuit, but also facilitates maintenance and debugging and later replacement, thereby improving the service life and use reliability of the device.

[0061] Secondly, the heating positive pole 53 and the heat dissipation positive pole 54 are both round head conductive column structures. This structure not only has good electrical conductivity in the contact track 52, but also enhances the mechanical stability of the device. The round head structure can better disperse mechanical stress and reduce the phenomenon of poor contact caused by contact wear, thereby ensuring the electrical connection consistency of the device during long-term operation.

[0062] Thirdly, the ceramic contact 551, the insulating contact 311, the upper contact 321, and the protection contact 431 are all round head insulating column structures. The design of these contacts not only has good stability in mechanical structure, but also provides high insulation protection in electrical performance. In particular, the high heat resistance and insulation of ceramic materials enable the contacts to maintain excellent performance in high temperature environments, avoiding insulation failure and electrical failure caused by overheating.

[0063] In addition, the guide rod 554 is a hollow ceramic cylindrical structure, which further enhances the insulation performance of the device. The hollow ceramic structure not only reduces the weight of the guide rod 554, reducing the driving load of the thermal bimetallic strip 3, but also provides additional thermal insulation effect, avoiding the expansion and contraction of the guide rod 554 due to temperature changes, thereby ensuring the stable operation of the device under different temperature conditions.

[0064] In summary, this structure has significant beneficial effects in terms of insulation protection circuit. Through various insulation materials and structural designs, it not only ensures effective isolation between electrical components, preventing electrical short circuits and failures, but also prolongs its service life, reduces maintenance costs, and avoids safety risks in long-term use.

[0065] Embodiment Four

[0066] As Figure 5 shown, based on the above embodiments, this embodiment further gives the following contents:

[0067] The thermal bimetallic strip 3 includes a lower metal sheet 31 of inverted L-shaped structure, the lower metal sheet 31 is transversely provided with an upper metal sheet 32 with different thermal expansion coefficients, the upper contact 321 is arranged on the top surface of the upper metal sheet 32, and the insulation contact 311 is arranged on the bottom surface of the transverse part of the lower metal sheet 31.

[0068] Through the above technical means, first, the inverted L-shaped structure of the thermal bimetallic strip 3 and its unique design of the stacked welding and rolling provide the device with extremely high temperature response sensitivity. The lower metal sheet 31 of the inverted L-shaped structure will bend when heated, and this deformation directly affects the position of the upper metal sheet 32 and the upper contact 321, thereby realizing the measurement of temperature change. The lower metal sheet 31 of the stacked welding and rolling has a different thermal expansion coefficient from the lower metal sheet 31, which can increase the sensitivity and response speed of the thermal bimetallic strip 3, so that it can more quickly and accurately reflect the change of the environment temperature.

[0069] Second, the upper contact 321 is arranged on the top surface of the upper metal sheet 32, and the insulation contact 311 is arranged on the bottom surface of the transverse part of the lower metal sheet 31. This arrangement not only ensures good contact between the contact and the thermal bimetallic strip 3, but also effectively reduces the influence of external environmental factors on the measurement accuracy. Through such design, the device can maintain stable mechanical contact while minimizing the interference and errors that may be introduced in temperature measurement, ensuring the accuracy and reliability of temperature feedback.

[0070] Furthermore, the structural characteristics of the thermal bimetallic strip 3 ensure highly stable performance over a wide temperature range. Whether in extreme high or low temperatures, the thermal bimetallic strip 3 reliably reflects temperature changes and is unaffected by fluctuations in the external ambient temperature. This stability is unmatched by traditional temperature measurement methods. The application of the thermal bimetallic strip 3 is particularly important and reliable in industrial manufacturing and scientific research, where extremely high temperature measurement accuracy is required.

[0071] In summary, the adaptive temperature regulation protection device based on the thermal bimetallic strip 3 offers significant advantages in improving temperature measurement accuracy. Its design structure and material properties enable the device to measure temperature with extremely high accuracy and stability, ensuring the consistency and reliability of temperature feedback in complex and changing environments.

[0072] Example 5

[0073] like Figure 1 As shown, based on the above embodiment, this embodiment further provides the following content:

[0074] The thermal bimetallic strip 3 is further provided on the other side of the bottom of the thermal conductive fin 2 , and the movable contact 5 is also provided on one side of the thermal bimetallic strip 3 .

[0075] Through the above-mentioned technical means, by placing a thermal bimetallic strip 3 and a movable contact 5 on either side of the bottom of the thermal fin 2, this configuration makes the device more sensitive to temperature changes. The dual thermal bimetallic strips can more evenly sense temperature changes in the thermal fins, thereby more accurately reflecting the actual temperature of the heating element. This design reduces the localized heat conduction hysteresis that may occur with a single thermal bimetallic strip, allowing them to compensate for and balance local temperature fluctuations, thereby improving the accuracy and reliability of the overall temperature measurement system.

[0076] The working principle and use process of the present invention:

[0077] The application has two modes of heat dissipation adjustment state and heating adjustment state. In the heat dissipation adjustment state, the thermal bimetallic strip 3 is heated and deformed downward, so that the insulation contact 311 in close contact with it continues to move downward under the action of the reset spring 552, and the guide column 55 moves downward, causing the heat dissipation negative electrode 56 to be in conductive connection with the heat dissipation positive electrode 54, and the heat dissipation positive electrode 54 starts to contact the sliding rheostat wire 555 (copper coil) that moves downward, realizing an effective power supply circuit, starting the heat dissipation fan to dissipate heat from the heat generating element 11. The speed of the fan changes linearly with the current, the greater the current, the faster the speed, and the distance between the heat dissipation power supply negative electrode and the heat dissipation positive electrode 54 changes linearly with the heat dissipation of the sliding rheostat wire 555 pulled by the thermal bimetallic strip 3, the smaller the distance, the greater the current (the sliding rheostat moves to the small resistance end), and at the same time, when the temperature reaches the limit value, the insulation contact 311 on the thermal bimetallic strip 3 synchronously pushes the protection contact 431 below it, so that the conductive ring 432 sleeved on it is separated from the total power supply positive electrode spring 42, directly breaking the total power supply circuit, avoiding damage to important components caused by excessive temperature, until the temperature returns to the appropriate range, the conductive ring 432 and the total power supply positive electrode spring 42 are recombined, and the equipment is powered again; in the heating adjustment state, the thermal bimetallic strip 3 is deformed upward at the end due to the low temperature conducted by the heat conduction fin 2, which drives the upper contact 321 to move upward, so that the ceramic contact 551 in close contact with it pulls the guide column 55 to move upward, at the same time, the heating positive electrode 53 starts to contact the sliding rheostat wire 555 (copper coil) that moves upward, realizing an effective circuit, starting the heating film, and the power of the heating film changes linearly with the current, the greater the current, the faster the speed, and the distance between the heating power supply negative electrode and the heating positive electrode 53 changes linearly with the heat dissipation of the sliding rheostat wire 555 pulled by the thermal bimetallic strip 3, the smaller the distance, the greater the current (the sliding rheostat moves to the small resistance end).

[0078] The above is only a preferred embodiment of the application, and is not intended to limit the application. Any modification, equivalent replacement and improvement within the spirit and principles of the application should be included in the protection scope of the application.
