Abstract

This application provides a temperature control device and a motor drive system, relating to the field of temperature control technology. In this temperature control device, because the temperature control module is in close contact with the object being controlled, when the object is a rotating device, the temperature of the rotating device can be approximately stabilized at a set temperature. Furthermore, since the output terminal of the power module is connected to the transmitting circuit, and the power terminal of the temperature control module is connected to the receiving circuit, and the transmitting circuit wirelessly transmits power to the receiving circuit, the power module can supply power to the temperature control module. Since both the temperature control module and the transmitting circuit are located on the object being controlled, the power supply to the temperature control module is achieved wirelessly. Therefore, when the object being controlled is a rotating device, a conductive slip ring is no longer needed, thereby reducing the cost of temperature control for the rotating device. In summary, this application reduces the cost of temperature control for the rotating device while simultaneously stabilizing its temperature at a set temperature.

Description

Technical Field

[0001] This invention relates to the field of temperature control technology, and in particular to a temperature control device and a motor drive system. Background Technology

[0002] Currently, for rotating devices, if temperature control is required, a contact-type temperature control method is typically used. Specifically, in the contact-type temperature control method, the temperature control module is in close contact with the rotating device, meaning the temperature control module measures the temperature of the rotating device through contact, and the power supply to the temperature control module is achieved through a conductive slip ring.

[0003] Because the temperature control module measures the temperature of the rotating device through contact, the deviation between the temperature detected by the module and the actual temperature of the rotating device is small, allowing the temperature of the rotating device to be approximately stable at the set temperature. However, the conductive slip ring has a limited lifespan, necessitating frequent replacements and increasing the cost of temperature control for the rotating device.

[0004] Therefore, how to reduce the cost of temperature control for the rotating device while ensuring that the temperature of the rotating device is approximately stable at the set temperature is an urgent technical problem to be solved. Summary of the Invention

[0005] In view of this, the present invention provides a temperature control device and a motor drive system to reduce the cost of temperature control of the rotating device while making the temperature of the rotating device approximately stable at the set temperature.

[0024] Another aspect of this application provides a motor drive system, comprising: a second controller, a motor controller, a motor, and a temperature control device as described in any of the preceding aspects of this application; wherein:

[0025] The temperature control module in the temperature control device is attached to the motor.

[0026] The second controller is communicatively connected to the motor controller, and the motor is controlled by the motor controller.

[0027] Optionally, it further includes: a first communication unit; the first communication unit includes: a first wireless communication module and a second wireless communication module; wherein:

Therefore, when the temperature-controlled object is a rotating device, a conductive slip ring is no longer needed, i.e., frequent replacement of the conductive slip ring is no longer required, thereby reducing the cost of temperature control for the rotating device. In summary, this application reduces the cost of temperature control for the rotating device while simultaneously stabilizing its temperature at the set temperature. Attached Figure Description

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0040] In this application, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0041] To reduce the temperature control cost of the rotating device while maintaining its temperature approximately at a set temperature, another embodiment of this application provides a temperature control device, the specific structure of which is as follows: Figure 1 As shown, it specifically includes: a temperature control module 10, a power supply module 20, and a wireless power transmission module 30. The wireless power transmission module 30 includes a receiving circuit 31 and a transmitting circuit 32. The connection relationships between the various components are as follows:

[0042] The temperature control module 10 and the receiving circuit 31 are both installed on the temperature control object of the temperature control device, and the temperature control module 10 is attached to the temperature control object.

[0043] It should be noted that, in Figure 1 In order to simplify the view, the positional relationship between the temperature control module 10 and the temperature control object, as well as the positional relationship between the receiving circuit 31 and the temperature control object, are not shown.

[0044] Optionally, the temperature control object can be a rotating device, such as a motor, or a non-rotating device. No specific limitation is made here, and it can be determined according to the specific circumstances. All of them are within the protection scope of this application.

[0045] The power supply terminal of the temperature control module 10 is connected to the receiving circuit 31, and the output terminal of the power supply module 20 is connected to the transmitting circuit 32. The transmitting circuit 32 is used to wirelessly transmit power to the receiving circuit 31, and the power supply module 20 is used to provide DC power.

[0046] In this temperature control device, because the temperature control module 10 is in close contact with the object being controlled, the temperature of the object can be approximately stabilized at the set temperature. Therefore, when the object being controlled is a rotating device, the temperature of the rotating device can also be approximately stabilized at the set temperature. Furthermore, since the output terminal of the power module 20 is connected to the transmitting circuit 32, and the power terminal of the temperature control module 10 is connected to the receiving circuit 31, and the transmitting circuit 32 wirelessly transmits power to the receiving circuit 31, the power module 20 can supply power to the temperature control module 10. Since both the temperature control module 10 and the transmitting circuit 32 are located on the object being controlled, the power supply to the temperature control module 10 is achieved wirelessly. Therefore, when the object being controlled is a rotating device, a conductive slip ring is no longer needed, eliminating the need for frequent replacements and reducing the cost of temperature control for the rotating device. In summary, this application achieves approximately stabilization of the temperature of the rotating device at the set temperature while reducing the cost of temperature control for the rotating device.

[0047] Another embodiment of this application provides a specific implementation of the temperature control module 10, the specific structure of which is as follows: Figure 2 As shown, it specifically includes: a first controller 11, a temperature detection module 12, and a heating module 13. The connection relationships between the components are as follows:

[0048] The temperature detection module 12 is attached to the object being controlled, and its output is connected to the input of the first controller 11. The power supply of the temperature detection module 12 is connected to the receiving circuit 31. The temperature detection module is used to detect the temperature of the object being controlled and sends the detection result to the first controller 11.

[0049] The heating module 13 is attached to the object being controlled. The control terminal of the heating module 13 is connected to the output terminal of the first controller 11, and the power supply terminal of the heating module 13 is connected to the receiving circuit 31. The first controller 11 is used to adjust the heating power of the heating module 13 according to the detection result of the temperature detection module 12.

[0050] In a specific example, the first controller 11 uses PID regulation to adjust the heating power of the heating module 13 according to the detection results of the temperature detection module 12, so as to realize closed-loop temperature control of the object being controlled, so that the temperature of the object being controlled is stable at the set temperature.

[0051] The above example only shows one specific adjustment method adopted by the first controller 11. In practical applications, there are other methods, including but not limited to this one. No specific limitation is made here. It can be determined according to the specific situation, and all of them are within the protection scope of this application.

[0052] In this embodiment, since the first controller 11 that implements temperature control is an independent controller, the first controller 11 can still achieve temperature control even if other controllers malfunction, which reduces the possibility of other controllers affecting temperature control and thus improves the reliability of temperature control.

[0053] The above is only one specific implementation of the temperature control module 10. In practical applications, it includes, but is not limited to, this one. It can be determined according to the specific situation and is within the protection scope of this application.

[0054] Another embodiment of this application provides a specific implementation of the heating module 13, the specific structure of which is as follows: Figure 3 As shown, it specifically includes: a power conversion circuit 131 and a heating device 132. The connection relationships between the devices are as follows:

[0055] The heating element 132 is attached to the object being controlled.

[0056] The first side of the power conversion circuit 131 is connected to the power supply terminal of the heating device 132, and the second side of the power conversion module is connected to the receiving circuit 31. The power conversion circuit 131 is controlled by the first controller 11. Specifically, the first controller 11 is used to adjust the output power of the power conversion circuit 131 according to the detection result of the temperature detection module 12.

[0057] In a specific example, the first controller 11 adjusts the output power of the power conversion circuit 131 by adjusting the pulse width of the signal received by each switch in the power conversion circuit 131.

[0058] The above example only shows one specific implementation of adjusting the output power of the power conversion circuit 131. In practical applications, there are other methods, including but not limited to this one. No specific limitation is made here. It can be determined according to the specific situation, and all are within the protection scope of this application.

[0059] Optionally, the power conversion circuit 131 can be a DC / DC conversion module or an AC / DC conversion module. No specific limitation is made here. The specific choice depends on whether the output of the receiving circuit 31 is AC or DC, and both are within the protection scope of this application.

[0060] It should be noted that DC / DC conversion modules and AC / DC conversion modules are already very mature technologies, and will not be described in detail here.

[0061] The above is only one specific implementation of the heating module 13. In practical applications, including but not limited to this, any device that can generate heat and whose heating power is controllable is within the protection scope of this application. No specific limitation is made here, and it can be determined according to the specific situation.

[0062] Another embodiment of this application provides another specific implementation of the heating module 13, the specific structure of which is as follows: Figure 4 As shown. This embodiment, based on the previous embodiment, also includes: a temperature protection switch 133. The connection relationship between this device and other devices is specifically described as follows:

[0063] Temperature protection switch 133 is connected in series in the connection path of heating device 132. Temperature protection switch 133 is used to turn itself off when its temperature exceeds the preset temperature, that is, temperature protection switch 133 realizes over-temperature protection.

[0064] If the temperature of the temperature protection switch 133 is higher than the preset temperature, it indicates that the temperature of the temperature protection switch 133 is too high, which means that the current in the connection path of the heating device 132 is too high. Conversely, if the temperature of the temperature protection switch 133 is less than or equal to the preset temperature, it indicates that the temperature of the temperature protection switch 133 is not too high, which means that the current in the connection path of the heating device 132 is not too high. In practical applications, the preset temperature is set according to the specific situation of the connection path of the heating device 132, and no specific limitation is made here.

[0065] It should be noted that the temperature protection switch 133 is already very mature in the existing technology, and will not be described in detail here.

[0066] In this embodiment, since the temperature protection switch 133 can turn itself off when its own temperature is higher than the preset temperature, that is, the temperature protection switch 133 realizes over-temperature protection, this embodiment can reduce the possibility of the heating module 13 causing damage to the temperature-controlled object, thereby improving the safety of the temperature control device.

[0067] Another embodiment of this application provides a specific implementation of the temperature detection module 12, which specifically includes a bridge-type temperature measurement circuit. The connection relationship between this circuit and other devices is described in detail below:

[0069] In a bridge-type temperature measurement circuit, the temperature-sensing resistor is in contact with the object being temperature controlled.

[0070] Optionally, the temperature sensing resistor can be PT100. In practical applications, it may include, but is not limited to, PT100. It may be determined according to the specific circumstances and is within the scope of protection of this application.

[0071] The above is only one specific implementation of the temperature detection module 12. In practical applications, including but not limited to this, any implementation that can perform temperature detection is within the protection scope of this application. No specific limitation is made here, and it can be determined according to the specific situation.

[0072] Another embodiment of this application provides a specific implementation of the power module 20, the specific structure of which is as follows: Figure 5 As shown, it specifically includes: AC / DC conversion module 21, filter circuit 22, and DC / DC conversion module 23. The connection relationships between the components are as follows:

[0073] The AC side of AC / DC converter module 21 serves as the input terminal of power supply module 20, receiving the supply voltage. The DC side of AC / DC converter module 21 is connected to one end of filter circuit 22. The other end of filter circuit 22 is connected to the first side of DC / DC converter module 23. The second side of DC / DC converter module 23 is connected to transmitting circuit 32.

[0074] Optionally, the AC / DC conversion module 21 can be a power adapter or an AC / DC conversion circuit. In practical applications, including but not limited to these, any implementation that can convert AC power to DC power is within the protection scope of this application. No specific limitation is made here, and it can be determined according to the specific situation.

[0075] It should be noted that power adapters and AC / DC conversion circuits are already very mature technologies, and will not be described in detail here.

[0076] Optionally, the DC / DC conversion module 23 can be a power conversion chip or a DC / DC conversion circuit. In practical applications, including but not limited to these, any implementation that can convert DC power into DC power of other voltages is within the protection scope of this application. No specific limitation is made here, and it can be determined according to the specific situation.

[0077] It should be noted that power conversion chips and DC / DC conversion circuits are already very mature technologies, and will not be described in detail here.

[0078] In this embodiment, the inclusion of the filter circuit 22 reduces noise and electromagnetic interference in the DC power supply after the DC side of the AC / DC conversion module 21. Furthermore, the presence of a DC / DC conversion module 23 after the AC / DC conversion module 21 allows the power supply module 20 to power different modules.

[0079] The above is only one specific implementation of the power module 20. In practical applications, there are other implementations, including but not limited to this one. No specific limitation is made here. The implementation can be determined according to the specific circumstances, and all of them are within the protection scope of this application.

One end of the receiving circuit is connected to the power supply terminal of the temperature control module 10, and the other end is connected to the receiving coil.

[0082] The transmitting circuit converts direct current (DC) to alternating current (AC). The transmitting coil generates a vibrating magnetic field when AC current flows within it. The receiving coil induces AC current in the vibrating magnetic field generated by the transmitting coil. The receiving circuit then converts the AC current back to DC.

[0083] It should be noted that the transmitting circuit, transmitting coil, receiving circuit, and receiving coil are already very mature technologies, and will not be described in detail here.

[0084] The above is only one specific embodiment of the transmitting circuit 32 and the receiving circuit 31.
