Abstract

This utility model relates to an inductive cooling structure, which includes a component base, an inductor coil disposed on the component base, a heat-conducting plate disposed on the side of the inductor coil, and a heat-conducting block disposed on the component base in contact with the heat-conducting plate. A heat-conducting channel is disposed within the heat-conducting block, and a refrigerant pipe enters the heat-conducting block from one end of the heat-conducting channel and exits the heat-conducting block from the other end of the heat-conducting channel. The refrigerant circulates in the refrigerant pipe to remove heat from the heat-conducting block. This inductive cooling structure conducts heat through the heat-conducting block and dissipates heat through the refrigerant pipe inside it, eliminating the need for a cooling fan.

Even with ultra-high-speed refrigerant circulation, no additional heat will be generated within the system or device.

Description

Technical Field

[0001] This utility model relates to the field of inductors, and more particularly to an inductor cooling structure. Background Technology

[0002] In existing electronic and electrical systems and equipment, inductors are important components. Inductors generate relatively a lot of heat, requiring heat dissipation. The current method is to configure a separate heat sink for the inductor, with the heat-conducting surface of the heat sink in contact with the inductor through an insulating heat-conducting layer, and then a separate cooling fan blows air onto the fins of the heat sink to cool the inductor. However, this method has the following drawbacks: the separate heat sink and cooling fan occupy a lot of space, and since it only cools the inductor, the space utilization is not high. Furthermore, in traditional air-cooling methods, the cooling fan also generates heat, so the fan power cannot be too high, resulting in low overall cooling efficiency and failing to meet the cooling requirements of high-power inductors. Utility Model Content

[0003] To overcome the above problems, this utility model provides an inductive cooling structure. The technical solution adopted by this utility model to solve its technical problems is as follows:

[0004] An inductive cooling structure includes a component base, an inductor coil disposed on the component base, a heat-conducting plate disposed on the side of the inductor coil, and a heat-conducting block disposed on the component base in contact with the heat-conducting plate. A heat-conducting channel is disposed inside the heat-conducting block, and a refrigerant pipe enters the heat-conducting block from one end of the heat-conducting channel and exits the heat-conducting block from the other end of the heat-conducting channel. The refrigerant circulates in the refrigerant pipe to carry away the heat on the heat-conducting block.

[0005] Furthermore, the heat-conducting plate includes an insulating layer and a metal heat-conducting sheet, with the insulating layer sandwiched between the side of the inductor coil and the metal heat-conducting sheet, and the metal heat-conducting sheet and the heat-conducting block in contact.

[0006] Furthermore, the metal heat-conducting sheet extends in the direction of the heat-conducting block to form an extension plate, which contacts the upper surface of the heat-conducting block to increase the contact area between the metal heat-conducting sheet and the heat-conducting block.

[0007] Furthermore, the side of the metal heat-conducting plate extends towards the heat-conducting block to form an extension plate, which contacts the side of the heat-conducting block; the refrigerant pipe is coiled in a "mosquito coil" shape and abuts against the metal heat-conducting plate.

[0008] Furthermore, the heat-conducting block includes a detachable and fixedly connected base and a top cover. The upper surface of the base is provided with a lower half-groove, and the lower surface of the top cover is provided with a corresponding upper half-groove. The base and the top cover are combined to form a heat-conducting block, and the lower half-groove and the upper half-groove are combined to form a heat-conducting channel.

[0009] Furthermore, the heat conduction channels are arranged in an "S" shape within the heat conduction block to increase the contact area between the heat conduction channels and the heat conduction block.

[0010] Furthermore, the refrigerant piping is made of copper or aluminum.

[0011] The beneficial effects of this utility model are as follows:

[0012] This inductor cooling structure includes a component base, an inductor coil mounted on the base, a heat-conducting plate on the side of the inductor coil, and a heat-conducting block on the base that contacts the heat-conducting plate. A heat-conducting channel is located within the heat-conducting block, and a refrigerant pipe enters the heat-conducting block from one end of the channel and exits from the other end. The refrigerant circulates within the pipe to carry away heat from the heat-conducting block. This inductor cooling structure conducts heat through the heat-conducting block and dissipates heat through the refrigerant pipe within it, eliminating the need for a cooling fan. The heat-conducting block and its internal refrigerant pipe occupy little space and can simultaneously dissipate heat from both the inductor coil and the component base, resulting in high space utilization. The refrigerant serves as the cold source, providing high cooling efficiency, and the refrigerant drive source can be located outside the device. Even with ultra-high-speed refrigerant circulation, no additional heat is generated within the system or device. Attached Figure Description

[0020] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of "an inductive cooling structure" of this utility model is provided in conjunction with the accompanying drawings.

[0021] See Figure 1In this embodiment, the inductor cooling structure includes a component base 100, on which an inductor coil 200 and a heat-conducting block 300 are disposed. A heat-conducting plate 201 is disposed on the side of the inductor coil 200. The heat-conducting block 300 and the heat-conducting plate 201 are in surface contact to conduct heat from the inductor coil 200. A heat-conducting channel is disposed inside the heat-conducting block 300. A refrigerant pipe 301 enters the heat-conducting block 300 from one end of the heat-conducting channel and exits the heat-conducting block 300 from the other end of the heat-conducting channel. The refrigerant pipe 301 is preferably a copper pipe or an aluminum pipe. The wall of the copper pipe is in close contact with the inner wall of the heat-conducting channel inside the heat-conducting block 300. The refrigerant pipe 301 is connected to an external refrigerant delivery device. The refrigerant circulates in the refrigerant pipe 301 to carry away the heat on the heat-conducting block 300, thereby achieving efficient cooling of the inductor coil 200.

[0022] It should be noted that this inductor cooling structure conducts heat from the inductor coil 200 through the heat-conducting block 300 and cools the inductor coil 200 through the circulation of refrigerant in the refrigerant pipe 301 within the heat-conducting block 300. This eliminates the need for a cooling fan and heat sink. Furthermore, since the heat-conducting block 300 is mounted on the component base 100, heat generated by other components can also be conducted to the heat-conducting block 300 through the component base 100 and carried away by the refrigerant. This allows for the cooling of the inductor coil 200 and surrounding components while occupying only a small amount of space, resulting in high space utilization. Moreover, because the refrigerant is a low-temperature heat source, its cooling efficiency is higher than that of air cooling. Additionally, the refrigerant drive end of the refrigerant pipe 301 can be located outside the system or device, ensuring that even with ultra-high-speed refrigerant circulation, no additional heat source is generated inside the system or device. This makes the cooling efficiency of this structure extremely high.

[0023] See further Figure 2 In this embodiment, the heat-conducting plate 201 includes an insulating layer 2011 and a metal heat-conducting sheet 2012. The insulating layer 2011 is sandwiched between the side of the inductor coil 200 and the metal heat-conducting sheet 2012. The insulating layer 2011 is preferably a thermally conductive insulating silicone sheet, which plays the role of conducting heat and preventing electrical interference between the inductor coil 200 and the metal heat-conducting sheet 2012. The metal heat-conducting sheet 2012 and the heat-conducting block 300 are in surface contact.

[0024] More specifically, in this embodiment, the metal heat-conducting sheet 2012 extends in the direction of the heat-conducting block 300 to form an extension plate 2013. The extension plate 2013 is in contact with the upper surface of the heat-conducting block 300 to increase the contact area between the metal heat-conducting sheet 2012 and the heat-conducting block 300, thereby improving the efficiency of conducting heat from the inductor coil 200 to the heat-conducting block 300 and thus improving the heat dissipation efficiency.

[0025] Furthermore, in other embodiments, the metal heat-conducting sheet 2012 can also extend from the side towards the heat-conducting block 300 to form an extension plate 2013. The extension plate 2013 contacts the side of the heat-conducting block 300 to increase the contact area and thus improve the heat conduction efficiency. On this basis, the refrigerant pipe 301 can be coiled in a "mosquito coil" shape and abut against the metal heat-conducting sheet 2012. This part of the refrigerant pipe 301 is in direct contact with the metal heat-conducting sheet 2012. In this way, the heat of the inductor coil 200 can be conducted through the heat-conducting plate 201 to the heat-conducting block 300 and then carried away by the refrigerant in the refrigerant pipe 301, or it can be carried away directly by the refrigerant in the refrigerant pipe 301 through the heat-conducting plate 201. This further improves the heat dissipation efficiency of the inductor coil 200.

[0026] See also Figure 2 In this embodiment, the heat-conducting block 300 includes a detachably fixed base 302 and a top cover 303. The upper surface of the base 302 is provided with a lower half-groove 304, and the lower surface of the top cover 303 is provided with an upper half-groove 305. The base 302 and the top cover 303 are combined to form the heat-conducting block 300, and the lower half-groove 304 and the upper half-groove 305 are combined to form a heat-conducting channel. This facilitates the installation and disassembly of the refrigerant pipe 301 and facilitates subsequent maintenance and replacement.

[0027] Furthermore, in some embodiments, the heat conduction channels are arranged in an "S" shape within the heat conduction block 300 to increase the contact area between the heat conduction channels and the heat conduction block 300 and improve heat dissipation efficiency.
