[0005] In order to solve the above technical problem, the utility model provides a temperature regulation device for jig heat dissipation cooling, it includes a power module, a temperature sensor, a conversion circuit, a processor, a relay, a fan and an external fan power supply. The power module is used to provide power. The temperature sensor is used to sense a temperature value of a jig, and according to the temperature value, a resistance value signal is converted. The conversion circuit is connected to the temperature sensor, and the resistance value signal is converted into a voltage signal. The processor converts the voltage signal into a relative temperature value, and compares the relative temperature value with a preset threshold temperature upper limit value and a threshold temperature lower limit value to generate a control signal. The relay is connected between the external fan power supply and the fan, and according to the control signal, it is decided whether the power supply of the external fan power supply is provided to the fan. When the relative temperature value is higher than the threshold temperature upper limit value, the processor generates the corresponding control signal to control the relay to close, so that the power supply of the external fan power supply is provided to the fan. When the relative temperature value reduces to the threshold temperature lower limit value, the processor generates the corresponding control signal to control the relay to open, and stops providing the external fan power supply to the fan.

Based on the control signal, it determines whether to supply power to the fan from the external fan power supply. This facilitates the monitoring and adjustment of fixture temperature, avoiding the impact of excessive temperature on product quality. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Before the present utility model is described in detail, it should be noted that similar elements are represented by the same reference numerals in the following description.
[0014] Please see Figure 1 As shown in the figure, a preferred embodiment of this utility model discloses a temperature control device 10 for heat dissipation and cooling of a fixture, which includes a power module 110, a temperature sensor 120, a conversion circuit 130, a processor 140, a relay 150, a fan 160, and an external fan power supply 170. The temperature control device 10 of this utility model uses the processor 140 to monitor the resistance signal returned by the temperature sensor 120. After the conversion circuit 130 converts the signal into a voltage signal, the processor 140 converts the voltage signal into a relative temperature value. Based on whether the relative temperature value is higher than the upper limit of the threshold temperature or lower than the lower limit of the threshold temperature, a control signal is generated, and based on the control signal, it is determined whether to supply power from the external fan power supply 170 to the fan 160. This application facilitates the monitoring and adjustment of fixture temperature, but is not limited thereto.
[0015] In one embodiment of this utility model, the power module 110 is used to supply power to the temperature control device 10, providing power assurance for the entire device. Specifically, it mainly ensures the stable operation of the temperature sensor 120, the processor 140, and the relay 150. Of course, the temperature control device 10 of this utility model can also be adjusted according to actual needs to specify which modules need to be powered by the power module 110, but this is not a limitation.
[0016] In one embodiment of this invention, the temperature sensor 120 is used to sense the temperature value of the fixture and convert the temperature value into a resistance signal. More specifically, in one embodiment of this invention, the temperature sensor 120 can be an NTC (Negative Temperature Coefficient) thermistor. Simply put, when the NTC thermistor senses an increase in the temperature of the fixture, the resistance value of the NTC thermistor will decrease. The NTC thermistor is prior art and will not be elaborated upon here. Of course, a suitable temperature sensor 120 can be selected according to actual conditions to meet different application requirements, but this is not a limitation.
[0017] In one embodiment of this invention, a conversion circuit 130 is disposed between the temperature sensor 120 and the processor 140. This circuit converts the resistance signal returned by the temperature sensor 120 into a voltage signal and then returns the voltage signal to the processor 140. More specifically, in one embodiment of this invention, the conversion circuit 130 can be a high-precision resistor voltage divider circuit. Simply put, a precise and stable resistor voltage divider circuit is achieved by using high-precision resistors to ensure accurate conversion. High-precision resistor voltage divider circuits are existing technology and will not be elaborated upon here. Of course, a suitable conversion circuit 130 can be selected according to actual needs to meet different voltage division requirements or other requirements, but this is not a limitation.
[0018] In one embodiment of this utility model, the processor 140, as the main control chip, can not only read the voltage signal converted by the temperature sensor 120 through the conversion circuit 130, but also convert the voltage signal into a relative temperature value through its built-in ADC module (Analog-to-Digital Converter). Of course, the processor 140 can also compare the relative temperature value with preset upper and lower threshold temperatures, thereby generating a control signal and outputting it to the relay 150 based on the comparison result, but this is not a limitation. Specifically, the processor 140 can be a microcontroller unit (MCU), but this is not a limitation; a suitable processor 140 can be selected according to the actual situation to meet different usage requirements, but this is not a limitation.
[0019] In one embodiment of this utility model, relay 150 is connected between external fan power supply 170 and fan 160, and determines whether to supply power from external fan power supply 170 to fan 160 based on a control signal. Specifically, relay 150 can be a normally open monostable electromagnetic relay. Simply put, relay 150 only allows current to pass through one circuit and ensures that relay 150 has only one stable state. Normally open monostable electromagnetic relays are existing technology and will not be elaborated upon here. Of course, a suitable relay 150 can be selected according to actual needs to meet different application requirements, but this is not a limitation.
[0020] In one embodiment of this utility model, the external fan power supply 170 is a power module 110 independent of the temperature control device 10. Simply put, the external fan power supply 170 is connected to the relay 150 to provide power to the fan 160. It should be noted that whether to provide power from the external fan power supply 170 to the fan 160 depends on the corresponding control signal generated by the processor 140, but is not limited thereto.
[0021] In detail, firstly, the power module 110 supplies power to the temperature sensor 120, processor 140, and relay 150 to ensure stable operation of the various modules within the temperature control device 10. Secondly, the temperature sensor 120 senses the temperature value of the fixture and converts it into a resistance signal, which is then transmitted back to the processor 140. During the transmission of the resistance signal, the temperature sensor 120 passes through a conversion circuit 130 to convert the resistance signal into a voltage signal, which is then transmitted back to the processor 140. Thirdly, the processor 140 uses its internal ADC module to convert the voltage signal into a relative temperature value to obtain an accurate temperature reading. It then compares the relative temperature value with preset upper and lower threshold temperatures to generate a control signal, which is output to the relay 150. The relay 150 then determines whether to supply power from the external fan power supply 170 to the fan 160 based on the control signal. It should be noted that when the relative temperature value acquired by the processor 140 is higher than the upper limit of the threshold temperature, the processor 140 generates a corresponding control signal to control the relay 150 to close, and enables the external fan power supply 170 to supply power to the fan 160, thereby providing power to the fan 160 and allowing the fan 160 to start running. When the relative temperature value acquired by the processor 140 drops to the lower limit of the threshold temperature, the processor 140 generates a corresponding control signal to control the relay 150 to open, stopping the supply of external fan power supply 170 to the fan 160, causing the fan 160 to stop working or stop running.
[0022] In summary, the temperature control device 10 of this invention monitors the resistance signal converted by the temperature sensor 120 through the processor 140, which is then converted into a voltage signal by the conversion circuit 130. The processor 140 converts the voltage signal into a relative temperature value, and generates a control signal based on whether the relative temperature value is higher than the upper limit of the threshold temperature or lower than the lower limit of the threshold temperature. Based on the control signal, it determines whether to supply power from the external fan power supply 170 to the fan 160. This facilitates the monitoring and adjustment of fixture temperature, preventing excessively high temperatures from affecting product quality. It is easy to use and has excellent practicality. Furthermore, other objectives and advantages of this invention can be further understood from the technical features disclosed herein.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
