[0002] A frequency converter is a device that controls the speed of an AC motor by changing the frequency of the power supply to the motor. It is widely used in industrial automation, household appliances and transportation, etc. The main function of the frequency converter is to adjust the output voltage and frequency, so that the motor can run at different speeds, thereby achieving the purpose of energy saving, improving efficiency and improving the performance of the equipment.

[0003] The frequency converter generates a large amount of heat during operation, so heat dissipation is a key issue in its design. Common heat dissipation methods include air cooling and cold plate cooling. Cold plate cooling is a method of transferring heat from the inside of the frequency converter to the cold plate through a heat-conducting material, and then exchanging heat with the external environment through the cold plate. Therefore, the cold plate is less affected by environmental factors, has high heat dissipation efficiency, low noise and long service life, and is particularly suitable for high-power-density and high-reliability applications.

[0004] Although cold plate cooling has high efficiency, it has a large volume and weight, which requires a lot of space inside the frequency converter, which limits the layout of other components inside the frequency converter, affecting the compactness and integration of the overall design. In addition, the installation and maintenance of the cold plate cooling system require additional space, further increasing the layout difficulty, thereby affecting the miniaturization and lightweight design of the frequency converter.

[0037] Referring to Figure 1 and Figure 2 , the embodiment of the present application provides a cooling structure for the first heat generating device 100 and the second heat generating device 200. The first heat generating device 100 and the second heat generating device 200 will generate heat when working, and the cooling structure can take away the heat generated by the first heat generating device 100 and the second heat generating device 200, so as to ensure that the temperature of the first heat generating device 100 and the second heat generating device 200 during working is maintained within a normal range, thereby ensuring that the first heat generating device 100 and the second heat generating device 200 can work continuously and stably.

[0038] In order to achieve heat dissipation of the first heat generating device 100 and the second heat generating device 200, the cooling structure can include a cold plate 10, and the first heat generating device 100 and the first heat generating device 100 can exchange heat with the cold plate 10, so as to dissipate heat of the first heat generating device 100 and the second heat generating device 200 through the cold plate 10. Specifically, the cold plate 10 is based on fluid cooling technology, and heat is taken away by circulating cooling liquid inside the cold plate 10. Generally, the cold plate 10 includes a substrate, a flow channel arranged in the substrate, and an inlet and an outlet connected to the flow channel. The substrate is made of high thermal conductivity material such as aluminum, copper, etc., and is used to absorb and conduct heat. The inlet and outlet are used for the inlet and outlet of the cooling liquid, and the cooling liquid circulates in the flow channel in the substrate to absorb the heat of the substrate.

[0039] In some embodiments, if the first heat generating device 100 and the second heat generating device 200 are directly arranged on the cold plate 10, the volume of the cold plate 10 will be large. Based on this, the cooling structure can further include a heat conducting member 20, the heat conducting member 20 has a fixing part 21, a connecting part 22 and a supporting part 23, the fixing part 21 is installed on the cold plate 10 and can exchange heat with the cold plate 10, the connecting part 22 is used to connect the fixing part 21 and the supporting part 23, and the fixing part 21 and the supporting part 23 have a height difference in the first direction X, and an accommodation space 30 can be formed between the supporting part 23 and the cold plate 10 in the first direction X.

[0040] In the embodiment, the above-mentioned first direction X can be the supporting direction of the cold plate 10 to the first heat generating device 100, for example, Figure 1In some embodiments, the first heat generating device 100 can be directly placed on the support portion 23 in the up-down direction, while in other embodiments, the first heat generating device 100 is fixed on the support portion 23 by means of bolts or the like, and at this time, the first direction X is parallel to the bolt direction for fixing the first heat generating device 100. It should be noted that the first direction can be determined according to the actual installation of the first heat generating device 100 and the second heat generating device 200, and the embodiments of the present specification do not limit this.

[0041] In the present embodiment, the fixing portion 21 can be a sheet-shaped structure with a certain thickness, which can be used to conduct heat. The fixing portion 21 can be rectangular, semicircular, or other possible heat-conducting structures. The fixing portion 21 can be a heat-conducting component such as a uniform temperature plate. The specific configuration can be determined according to actual conditions, and the embodiments of the present specification do not limit this.

[0042] In the present embodiment, the connecting portion 22 can be a heat-conducting component such as a uniform temperature plate, and the connecting portion can be a sheet-shaped structure with a certain thickness. The connecting portion 22 is inclined with respect to the fixing portion 21, as shown in Figure 1 so that the support portion 23 and the fixing portion 21 have a height difference. The connecting portion 22 can also be a columnar structure extending in the first direction X or other shaped support structures, and the specific configuration can be determined according to actual conditions,

[0043] In the present embodiment, the support portion 23 can be a sheet-shaped structure with a certain thickness, which can be used to conduct heat. The support portion 23 can be rectangular, semicircular, or other possible heat-conducting structures. The support portion 23 can be a heat-conducting component such as a uniform temperature plate. The specific configuration can be determined according to actual conditions, and the embodiments of the present specification do not limit this.

[0044] The side of the support portion 23 away from the cold plate 10 in the first direction X is used to install the first heat generating device 100, and when the first heat generating device 100 is installed on the support portion 23, the first heat generating device 100 can exchange heat with the support portion 23, i.e. the heat of the first heat generating device 100 can be transferred to the support portion 23. The heat of the support portion 23 can be transferred to the fixing portion 21 through the connecting portion 22, and finally the heat of the first heat generating device 100 is transferred to the cold plate 10 through the heat exchange between the fixing portion 21 and the cold plate 10, achieving the effect of dissipating heat from the first heat dissipating device.

[0045] The side of the cold plate 10 facing the support portion 23 is used to install the second heat generating device 200, and when the second heat generating device 200 is installed on the cold plate 10, the second heat generating device 200 is located in the accommodation space 30 and can exchange heat with the cold plate 10, i.e. the second heat generating device 200 is directly arranged on the cold plate 10, and the heat of the second heat generating device 200 is directly taken away by the cold plate 10, achieving the effect of the second heat dissipating device.

[0046] The cooling structure sets the first heat generating device 100 on the support portion 23 of the heat conducting member 20, and sets the second heat generating device 200 directly on the cold plate 10. In this way, the first heat generating device 100 can be arranged above the cold plate 10, and heat is transferred to the cold plate 10 through the heat conducting member 20 for heat dissipation. The first heat generating device 100 and the second heat generating device 200 can be stacked and placed without being placed on the cold plate 10, so as to effectively reduce the volume of the cold plate 10, improve the utilization rate of the internal space structure of the industrial control device, and facilitate the miniaturization and light weight of the industrial control device.

[0047] In some embodiments of the present application, the projection of the support portion 23 on the cold plate 10 along the first direction X is located away from the fixing portion 21, and the opposite ends of the connecting portion 22 are connected to the fixing portion 21 and the end of the support portion 23 facing each other. That is, the support portion 23 is not arranged directly above the fixing portion 21, and the support portion 23 and the fixing portion 21 are spaced apart in a second direction Y intersecting the first direction X. In this way, the space below the support portion 23 can be used for the accommodation space 30, thereby increasing the size of the accommodation space 30.

[0048] Further, since the support portion 23 is connected to the fixing portion 21 only through the connecting portion 22, the support portion 23 is in a suspended state. Once the first heat generating device 100 is heavy or subjected to vibration or other external force, the support portion 23 and the connecting portion 22 are prone to breakage at the joint. Therefore, in some embodiments, when the cooling structure is applied to an industrial control device, the industrial control device includes a housing, and the first heat generating device 100, the second heat generating device 200, and the cooling structure are arranged in the housing, and the support portion 23 is connected to the housing. In this way, by connecting the support portion 23 to the housing, the support portion 23 can be avoided from being suspended, and the service life of the heat conducting member 20 is improved.

[0049] It should be noted that in other embodiments, the projection of the support portion 23 on the cold plate along the first direction X can also partially overlap the fixing portion 21, as long as the accommodation space 30 formed between the support portion 23 and the cold plate 10 is sufficient to accommodate the second heat generating device 200. The heat conducting member 20 can be designed according to the actual space of the product, and the embodiments of the present application do not limit this.

[0050] Further, the support portion 23 and the fixing portion 21 are arranged in parallel, and the support portion 23 and the fixing portion 21 are spaced apart along a second direction Y intersecting the first direction X. The connecting portion 22 connects the ends of the support portion 23 and the fixing portion 21 close to each other, that is, the connecting portion 22 is arranged between the support portion 23 and the fixing portion 21, so that the heat conducting member 20 has a structure similar to "Z".

[0051] It should be noted that in some other embodiments, the shape of the heat-conducting element 20 can also be "Z" shaped or "T" shaped, etc. The specific shape setting can be designed according to the actual situation. The fixing part 21 is also located below the support part 23, and the other space below the support part 23 serves as the accommodating space 30. When the volume of the second heating device 200 is small, it is beneficial to the miniaturization of the overall cooling structure.

[0052] The fixing part 21, connecting part 22, and supporting part 23 of the heat-conducting component 20 can be integrally formed, so that the fixing part 21, connecting part 22, and supporting part 23 can be integrated as a whole. This not only improves the supporting strength of the heat-conducting component 20 for the first heating device 100, but also reduces the number of components in the cooling structure, facilitating the assembly of the heat-conducting component 20. Optionally, the heat-conducting component 20 can be formed by stamping copper or aluminum sheets.

[0053] In some embodiments of this application, when the cooling structure is applied within industrial control equipment, a connecting cable 300 is typically provided within the equipment to connect various components for data and power transmission. However, when the second heating element 200 is located within the accommodating space 30, if it is necessary to connect the second heating element 200 to other components located near the connecting portion 22 via the connecting cable 300, the connecting cable 300 must bypass the connecting portion 22, increasing its length. This is detrimental to cost savings and also makes future maintenance more difficult.

[0054] Based on this, the connecting part 22 can be provided with a through clearance opening, which is connected to the accommodating space 30. The connecting line 300 can pass through the accommodating space 30 through the clearance opening and pass through the connecting part 22, so that the connecting line 300 can pass through the connecting part 22 through the clearance opening, thereby reducing the length of the connecting line 300. In addition, the clearance opening can also play a role in fixing the connecting line 300.

[0055] In some implementations, see Figure 2 The clearance opening may include two openings, which are located at the two ends of the connecting part 22 in the third direction Z. The third direction Z intersects both the first direction X and the second direction Y. Figure 2 The up and down directions in the middle.

[0056] In some embodiments, the two clearance openings can be semi-circular. When the cooling structure is installed inside the housing of the industrial control equipment, the inner wall of the housing will close the semi-circular clearance openings, thereby fixing the connecting wire 300 inside the clearance openings. This ensures that the connecting wire 300 passes through the connecting part 22, while also fixing the connecting wire 300.

[0057] The cold plate 10 has a heat dissipation surface 11, the second heat generating device 200 can be arranged on the heat dissipation surface 11, the fixing portion 21 has a fixing surface 24, the heat dissipation surface 11 is parallel to and in contact with the fixing surface 24, so that the heat dissipation surface 11, the second heat generating device 200 and the fixing surface 24 are in contact with each other, thereby increasing the contact area of the cold plate 10, the second heat generating device 200 and the heat conducting member 20, so that the heat of the second heat generating device 200 and the heat of the heat conducting member 20 can be quickly transferred to the cold plate 10.

[0058] Further, the support portion 23 has a support surface 25, the support surface 25 is parallel to the heat dissipation surface 11, and the first heat generating device 100 can be arranged on the support surface 25. In actual use, in order to enable the first heat generating device 100 and the second heat generating device 200 to be stably arranged on the cooling structure, the heat dissipation surface 11 is usually arranged to be parallel to the horizontal direction, so that the second heat generating device can be stably arranged on the heat dissipation surface 11, and at the same time, since the support surface 25 is parallel to the heat dissipation surface 11, the first heat generating device 100 can also be stably arranged on the support surface 25.

[0059] Specifically, in some embodiments, due to the error of the manufacturing process, the fixing surface 24 and the heat dissipation surface 11 cannot be completely in contact, and there will be a gap between the support surface 25 and the heat dissipation surface 11, which will affect the heat transfer efficiency between the heat conducting member 20 and the cold plate 10, and further affect the heat dissipation effect of the first heat generating device 100. Therefore, the support portion 23 and the first heat generating device 100 are filled with heat-conducting silicone grease, so as to fill the gap between the fixing surface 24 and the heat dissipation surface 11 through the heat-conducting silicone grease, thereby improving the heat transfer efficiency between the heat conducting member 20 and the cold plate 10 and ensuring the heat dissipation effect of the first heat generating device 100.

[0060] And there will be a gap between the support surface 25 and the first heat generating device 100, and the heat dissipation surface 11 and the second heat generating device 200, therefore, heat-conducting silicone grease is filled between the support portion 23 and the first heat generating device 100, and between the cold plate 10 and the second heat generating device 200, so as to fill the gap between the support surface 25 and the first heat generating device 100, and the heat dissipation surface 11 and the second heat generating device 200 through the heat-conducting silicone grease, thereby ensuring the heat dissipation efficiency of the first heat generating device 100 and the second heat generating device 200.

[0061] In some embodiments of the present application, in order to fix the fixing portion 21 on the cold plate 10, a fixing hole is formed on the fixing portion 21, and the cooling structure further comprises a fastener, the fastener is arranged in the fixing hole and connected with the cold plate 10, so as to fix the heat conduction piece 20 on the cold plate 10. Alternatively, a threaded hole is formed on the cold plate 10, and the fastener is a bolt, the bolt is screwed with the cold plate 10 through the fixing portion 21, so as to fix the heat conduction piece 20 on the cold plate 10 by the bolt, and in other embodiments, the fastener can also be a buckle to fix the heat conduction piece 20 by buckling.

[0062] The embodiments of the present application also provide an industrial control device, which can comprise a first heat generating device, a second heat generating device and the cooling structure in any of the above embodiments. Wherein, the industrial control device can be a frequency converter, the first heat generating device 100 can be a power module, the power module is a core component of the frequency converter, which is used for high-frequency switching and current regulation, and a large amount of heat will be generated during the working process of the power module, so the power module is the main heat source in the frequency converter. The second heat generating device 200 is a reactor, which is used for filtering and suppressing current harmonics, and heat will be generated during the working process, especially under high current conditions. Of course, it can be understood that the above industrial control device can also be a driver, PLC, etc., and the above first heat generating device 100 and second heat generating device 200 can also be other possible heat generating devices, such as light emitting diode, resistor, inductor, etc., which can be determined according to actual conditions, and the embodiments of the present application are not limited thereto.

[0063] Further, the first heat generating device 100 or the second heat generating device 200 can be one of the heat generating devices such as power module, reactor, driver, PLC, etc., or can be multiple, i.e., multiple heat generating devices are arranged on the fixing portion 21 or the supporting portion 23 to form the first heat generating device 100 or the second heat generating device, which can be determined according to actual conditions, and the embodiments of the present application are not limited thereto.

[0064] In some embodiments of the present application, the power module is light in weight, and therefore can be arranged on the supporting portion 23, and the reactor is heavy, and therefore is directly arranged on the cold plate 10. In other embodiments, the first heat generating device 100 and the second heat generating device 200 can also be a rectifier bridge, a control panel, a brake unit and other components in the frequency converter. In still other embodiments, the industrial control device can also be a rectifier, an inverter, a current transformer and other internal components of the device which need to be cooled.

[0065] In actual use, the industrial control device can further include a driving pump, a radiator, a liquid storage tank and the like, and the cooling liquid is circulated between the cold plate 10, the radiator and the liquid storage tank by the driving pump. When the cooling liquid absorbs heat from the substrate, the heat in the cooling liquid can be dissipated to the environment by the radiator, and the cooled cooling liquid flows into the substrate to continue to absorb heat.

[0066] The cooling structure has at least the following advantages:

[0067] By arranging the fixed part 21 and the support part 23 with height difference on the heat conduction part 20, and arranging the first heat generating device 100 on the support part 23, and arranging the second heat generating device 200 directly on the cold plate 10. In this way, the first heat generating device 100 can be arranged above the cold plate 10, and the heat is transferred to the cold plate 10 by the heat conduction part 20 for heat dissipation. While ensuring that the first heat generating device 100 and the second heat generating device 200 can both dissipate heat through the cold plate 10, the first heat generating device 100 and the second heat generating device 200 can be stacked and placed, without the need to be placed entirely on the cold plate 10, thereby effectively reducing the volume of the cold plate 10, improving the utilization rate of the internal space structure of the industrial control device, and facilitating the miniaturization and light weight of the industrial control device.

[0068] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.

[0069] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the present application, and these are within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
