Description

Technical Field

[0001] This application belongs to the field of electrical equipment technology, and in particular relates to a radio frequency defrosting device and electrical equipment. Background Technology

[0002] Radio frequency (RF) defrosting devices, which utilize RF defrosting technology, are a common application of power amplifier circuits. RF defrosting technology uses electromagnetic waves to penetrate food, enabling the food to thaw evenly and quickly. Therefore, refrigerators equipped with RF defrosting devices are widely popular with consumers.

[0003] The electrode plate operates at a high temperature and requires heat dissipation. However, in some technologies, the heat dissipation of the electrode plate is not good, which causes heat to accumulate in the components inside the shielding shell, resulting in high electrode plate temperature and affecting the lifespan of the electrode plate. Utility Model Content

[0004] This application aims to solve, at least to some extent, the technical problem of electrode heat dissipation. To this end, this application provides a radio frequency defrosting device and electrical equipment.

[0010] The housing assembly has a transition port connecting the radio frequency cavity and the defrosting cavity. The housing assembly also has a second connection port communicating with the defrosting cavity and a first connection port communicating with the radio frequency cavity.

[0011] In this process, after entering the defrosting chamber, the gas passes through a transition port into the radio frequency cavity, allowing it to flow through the electrode plates located within the radio frequency cavity. This allows the gas to exchange heat with the electrode plates, carrying away the heat generated by the radiation radio frequency defrosting energy. This reduces heat buildup on the electrode plates, enabling them to dissipate heat in a timely manner. Consequently, it reduces the risk of damage to the electrode plates due to heat buildup, thereby improving the lifespan of the electrode plates.

[0054] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0055] It should be noted that all directional indications in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0056] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0057] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0058] A power amplifier circuit (also known as a power amplifier, power amplifier board, power amplifier module, etc.) is an amplifier circuit designed to output a large amount of power. Power amplifier circuits are usually used as the output stage of a multi-stage amplifier circuit, and the output stage is required to drive a certain load.

[0059] Power amplifier circuits are used in many electronic devices, such as driving instruments to deflect pointers, driving speakers to produce sound, and driving electrodes to transmit radio frequency signals. When installing a power amplifier circuit, a shielding enclosure is used to prevent electromagnetic interference to other electronic components.

[0060] Radio frequency (RF) defrosting devices, which utilize RF defrosting technology, are a common application of power amplifier circuits. RF defrosting technology uses electrodes to radiate electromagnetic waves that penetrate food, enabling the food to defrost evenly and quickly. Therefore, refrigerators equipped with RF defrosting devices are widely popular with consumers.

[0061] The electrode plate operates at a high temperature and requires heat dissipation. However, in related technologies, the heat dissipation effect of the electrode plate is poor, leading to heat accumulation and affecting its lifespan. The radio frequency defrosting device and electrical equipment provided in this application can improve the above problems. The radio frequency defrosting device and electrical equipment provided in this application can directly utilize external gas to dissipate heat from the electrode plate, increasing the heat exchange between the electrode plate and the gas, thereby improving the heat dissipation effect of the electrode plate, preventing heat accumulation within the electrode plate, and extending the electrode plate's lifespan.

[0062] This application is described below with reference to the accompanying drawings and specific embodiments:

[0063] Figure 1 This paper shows a first-view structural schematic diagram of the radio frequency defrosting device 10 provided in an embodiment of this application, as shown below. Figure 1 As shown, this application embodiment provides a radio frequency defrosting device 10, which can improve the heat dissipation effect inside the placement cavity 214.

[0064] Figure 2 This is a schematic diagram of the radio frequency defrosting device 10 provided in an embodiment of this application from a second perspective. Figure 3 It shows Figure 2 Sectional view at point BB. Figure 3 Hollow arrows indicate the direction of gas flow, such as Figure 1 , Figure 2 and Figure 3 As shown in the embodiment of this application, the radio frequency defrosting device 10 includes: a housing assembly 200 and a power amplifier assembly 100. The housing assembly 200 has a first air inlet 212, a first air outlet 213, a placement cavity 214 and a mounting cavity 223. The first air inlet 212 and the first air outlet 213 are both connected to the placement cavity 214, which is used to accommodate items to be defrosted. The power amplifier assembly 100 is installed in the mounting cavity 223.

[0065] The housing assembly 200 is the basic structure of the radio frequency defrosting device 10. An electrode plate 400 can be installed inside the placement cavity 214. The electrode plate 400 is electrically connected to the power amplifier assembly 100, which amplifies the radio frequency defrosting signal. The electrode plate 400 radiates radio frequency defrosting energy into the placement cavity 214, thereby defrosting the items inside. Because the electrode plate 400 radiates radio frequency defrosting energy into the placement cavity 214, it also generates heat. If the defrosting time is too long, heat accumulation can easily occur, affecting the operation of the electrode plate 400. Furthermore, after the items are defrosted, a large amount of heat may accumulate inside the placement cavity 214. To achieve rapid cooling, the placement cavity 214 also needs to be rapidly cooled after the items are defrosted. The first air inlet 212 and the first air outlet 213 are connected to the placement cavity 214. Gas enters the placement cavity 214 from the first air inlet 212 and then flows out of the placement cavity 214 from the first air outlet 213.

[0066] In some embodiments, the housing assembly 200 includes a cover 240 and a cylinder 230, the cover 240 being connected to one side of the cylinder 230, an installation cavity 223 being disposed within the cover 240, and a placement cavity 214 being disposed within the cylinder 230.

[0067] In some embodiments, the cylinder 230 further has a loading / unloading port 224 communicating with the placement cavity 214. The loading / unloading port 224 is located on the front side of the cylinder 230, the cover 240 is located on the rear side of the cylinder 230, and the mounting cavity 223 is located inside the cover 240, that is, the power amplifier assembly 100 is located on the rear side of the cylinder 230. Since the loading / unloading port 224 is provided on the front side of the cylinder 230, placing the power amplifier assembly 100 on the rear side of the cylinder 230 can minimize the space occupied by the power amplifier assembly 100 on the front side of the cylinder 230, so that the loading / unloading port 224 can be set as large as possible, thereby facilitating the user to pick up and place items to be thawed, and making the operation more convenient for the user.

[0068] In some embodiments, the cylinder 230 has a first connection port 216 communicating with the placement cavity 214, and the cover 240 also has an exhaust channel 246 communicating with the first connection port 216. A first exhaust port 213 is disposed on the cover 240 and communicates with the exhaust channel 246. That is, the exhaust channel 246 connects the first exhaust port 213 and the first connection port 216. Gas in the placement cavity 214 enters the exhaust channel 246 through the first connection port 216 and is then discharged from the first exhaust port 213. The cover 240 is located on the rear side of the cylinder 230. The cover 240 also has an air outlet channel 246 that is independent of the mounting cavity 223. The air outlet channel 246 is connected to the first connection port 216 of the placement cavity 214. The first air outlet 213 is located on the rear cover 242 so that the first air outlet 213 is also located on the rear side of the entire cabinet assembly 200. When the radio frequency defrosting device 10 is applied to refrigeration equipment such as refrigerators and freezers, the first air outlet 213 located on the rear side can be easily connected to the air duct of the refrigerator or freezer, and can discharge the heat-exchanged gas into the air duct, which can prevent hot air from lingering in the refrigerator or freezer and affecting the cooling effect.

[0069] In addition, since the loading and unloading port 224 is located on the front of the cabinet assembly 200, users will use the loading and unloading port 224 to take out and place items to be defrosted. Placing the first vent 213 on the rear cover 242 (i.e., on the rear of the cabinet assembly 200) can also prevent hot air from blowing on the user and improve the user experience.

[0070] In some embodiments, the air outlet channel 246 includes a first sub-channel 2462, a second sub-channel 2464, and a third sub-channel 2466. The first sub-channel 2462, the second sub-channel 2464, and the third sub-channel 2466 are connected in sequence. The first sub-channel 2462 and the third sub-channel 2466 are respectively disposed on both sides of the second sub-channel 2464 along the width direction X of the housing assembly 200, that is, the first sub-channel 2462 and the third sub-channel 2466 are respectively disposed on the left and right sides of the second sub-channel 2464.

[0071] The cover 240 includes a rear cover 242, a cover plate 244, and a fixing plate 249. The rear cover 242 and the cylinder 230 are connected to form an installation cavity 223. The cover plate 244 and the cylinder 230 form a first sub-channel 2462. The second sub-channel 2464 is disposed in the rear cover 242. The fixing plate 249 is connected to the rear cover 242 to form a third sub-channel 2466. The first air outlet 213 is disposed on the fixing plate 249. The first connection port 216 is connected to the first sub-channel 2462. The first air outlet 213 is connected to the third sub-channel 2466.

[0072] In some embodiments, the cover plate 244 can be disposed inside the rear cover 242, so that the cover plate 244, the rear cover 242 and the cylinder 230 together form the mounting cavity 223. In other embodiments, the cover plate 244 can be disposed on one side of the rear cover 242. Along the width direction X of the housing assembly 200, the rear cover 242 and the cover plate 244 can be disposed side by side, and the positions of the cover plate 244 and the rear cover 242 are not limited.

[0073] The fixing plate 249 is disposed on the outside of the rear cover 242. The fixing plate 249 can be roughly bent (it can be L-shaped or U-shaped, and the specific shape is not limited), so that the fixing plate 249 and the side and bottom surfaces of the rear cover 242 enclose to form the third sub-channel 2466.

[0074] The second sub-channel 2464 and the mounting cavity 223 are arranged side by side along the width direction X of the housing assembly 200. The second sub-channel 2464 can be located to the left of the mounting cavity 223, or the mounting cavity 223 can be located to the left of the second sub-channel 2464. The relative positions of the mounting cavity 223 and the second sub-channel 2464 are not specifically limited.

[0075] The third sub-channel 2466 can be located below the second sub-channel 2464, that is, the third sub-channel 2466 can be located to the lower left of the second sub-channel 2464, or the third sub-channel 2466 can be located to the lower right of the second sub-channel 2464.

[0076] Along the depth direction Y of the housing, the cover plate 244 and the cylinder 230 are spaced apart, and the gap between the cover plate 244 and the cylinder 230 forms the first sub-channel 2462. The gas flow direction of the first sub-channel 2462 is along the width direction X of the housing. Since the first connection port 216 is connected to the first sub-channel 2462 and the first outlet port 213 is connected to the third sub-channel 2466, when the second sub-channel 2464 is located on the left side of the mounting cavity 223, the gas flowing out from the first connection port 216 enters the first sub-channel 2462, flows to the left, enters the second sub-channel 2464, flows to the left after entering the second sub-channel 2464, enters the third sub-channel 2466 and flows backward, and finally exits from the first outlet port 213.

[0077] In other words, there is a certain angle between the gas flow direction of the first sub-channel 2462 and the gas flow direction of the second sub-channel 2464, and there is also a certain angle between the gas flow direction of the third sub-channel 2466 and the second sub-channel 2464. During the process of gas flowing from the first sub-channel 2462 to the second sub-channel 2464 and from the second sub-channel 2464 to the third sub-channel 2466, the gas flow direction will change. This can also slow down the gas flow rate blown out from the first outlet 213 to a certain extent, so as to avoid excessive gas flow rate and noise.

[0078] In addition, since the first connection port 216 is directly connected to the placement cavity 218, there is a certain angle between the gas flow direction of the first sub-channel 2462 and the gas flow direction of the second sub-channel 2464, and there is also a certain angle between the gas flow direction of the third sub-channel 2466 and the second sub-channel 2464. This results in a certain angle and distance between the first connection port 216 and the first air outlet 213, which minimizes the risk of electromagnetic waves radiating from the first air outlet 213 during the defrosting process.

[0079] Figure 4 This diagram illustrates the structure of the radio frequency defrosting device 10 provided in the embodiments of this application from a first explosion perspective. Figure 5 It shows Figure 4 A magnified view of a section at point I, as shown below. Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the cover 240 further includes a baffle 248 disposed inside the rear cover 242, and the baffle 248, the cylinder 230 and the rear cover 242 form a second sub-channel 2464.

[0080] The baffle 248 is located inside the rear cover 242. The baffle 248 can be connected to the cover 244 and also to the housing 110 of the power amplifier assembly 100. This allows the heat dissipation channel 132 of the power amplifier assembly 100 to be separated from the second sub-channel 464.

[0081] The baffle 248 is disposed inside the rear cover 242, dividing the internal space of the rear cover 242 into two parts: one part is the mounting cavity 223, and the other part is the second sub-channel 2464. The connection between the rear cover 242 and the cylinder 230 forms the mounting cavity 223, and the other part of the rear cover 242, together with the baffle 248 and the cylinder 230, forms the second sub-channel 2464.

[0082] In some embodiments, the cylinder 230 is provided with a groove 232 located in the placement cavity 214. A first connection port 216 is disposed within the groove 232. The groove 232 has an opening 234, and a cover plate 244 covers at least a portion of the opening 234 to form a first sub-channel 2462. The cover plate 244 covering at least a portion of the opening 234 can be either completely covering the opening 234 or only partially covering it. If the cover plate 244 completely covers the opening 234, an opening communicating with the second sub-channel 2464 can be formed in the cover plate 244. If the cover plate 244 only covers a portion of the opening 234, the portion of the opening 234 not covered by the cover plate 244 can directly communicate with the second sub-channel 2464.

[0083] The groove 232 is located in the placement cavity 214, meaning that along the depth direction Y of the housing assembly 200, the position of the groove 232 corresponds to the position of the placement cavity 214.

[0084] The groove 232 is located on the rear side of the cylinder 230 and is recessed into the interior of the cylinder 230. The groove 232 is located outside the placement cavity 214, so that the internal space of the groove 232 is located outside the placement cavity 214. The structure of the groove 232 can be used to set the first sub-channel 2462. This setting method can reduce the dimension of the box assembly 200 in the depth direction and make the entire radio frequency defrosting device 10 more compact.

[0085] Of course, in another embodiment, the cover plate 244 can be directly spaced from the cylinder 230 to form the first sub-channel 2462. In this arrangement, the cylinder 230 does not need to be provided with the inwardly recessed groove 232, and does not occupy the space of the placement cavity 214 inside the cylinder 230. More items to be thawed can be placed, and the capacity of the placement cavity 214 can be increased.

[0086] In addition, since the cover plate 244 covers the opening 234 of the groove 232, the end of the opening 234 away from the second sub-channel 2464 can have a certain gap with the cover plate 244. The gas flowing out from the first connection port 216 can enter the mounting cavity 223 through this gap and can be directly discharged through the second air outlet 222 connected to the mounting cavity 223. This arrangement allows the gas flowing out from the placement cavity 214 to be discharged from different positions, which can reduce wind resistance and also increase the gas flow rate in the entire placement cavity 214 to a certain extent, thereby improving the heat dissipation effect in the placement cavity.

[0087] In some embodiments, the radio frequency defrosting device 10 further includes an air intake element 300, which is connected to the air outlet channel 246. The air intake element 300 is a fan. Specifically, the air intake element 300 can be disposed outside the cover 240. The air intake element 300 can connect the second sub-channel 2464 and the third sub-channel 2466. The air inlet of the air intake element 300 is connected to the second sub-channel 2464, and the air outlet of the air intake element 300 is connected to the third sub-channel 2466. By connecting the second sub-channel 2464 and the third sub-channel 2466 through the air intake element 300, the air path of the air outlet channel 246 can be simplified, making the structure more compact.

[0088] The first connection port 216 can be located at the end of the cylinder 230 away from the loading port 224, that is, the first connection port 216 can be located on the rear side of the cylinder 230. This arrangement may increase the flow path of gas in the placement cavity 214, increase the heat exchange time between the gas and the electrode plate, cylinder 230 and the item to be thawed in the placement cavity 214, and also improve the heat dissipation effect.

[0089] Figure 6 It shows Figure 1 Sectional view at point AA. Figure 6 Hollow arrows indicate the direction of gas flow, such as Figure 5 and Figure 6 As shown, in some embodiments, the housing assembly 200 includes a top cover 260 and a cylindrical body 230. A placement cavity 214 is disposed inside the cylindrical body 230. The top cover 260 is connected to the cylindrical body 230 to form an air intake channel 262. The cylindrical body 230 has a second connection port 218, which communicates with the placement cavity 214. A first air inlet 212 is disposed on the top cover 260. The air intake channel 262 communicates with the first air inlet 212 and the second connection port 218.

[0090] The top cover 260 is located outside the cylinder 230, forming an air inlet channel 262 with the cylinder 230. The top cover 260 is positioned at the top of the cylinder 230, allowing external gas to enter the placement cavity 214 from the top of the cylinder 230. Within the placement cavity 214, gas flows to the second connection port 218, and then from the second connection port 218 to the air outlet channel 246. Since the first air inlet 212 is located at the rear of the entire housing assembly 200, the air inlet channel 262 allows gas to enter the placement cavity 214 from other locations within the cylinder 230. Because the first air outlet 213 is also located at the rear of the cylinder 230, the air inlet channel 262 extends the gas flow path within the placement cavity 214, increasing the heat exchange time and improving heat dissipation efficiency.

[0091] In some embodiments, the cylinder 230 has a loading port 224 for loading and unloading items to be thawed. Along the depth direction Y of the housing assembly 200, a second connection port 218 is located near the loading port 224, and a first air inlet 212 is located away from the loading port 224.

[0092] The loading / unloading port 224 is located on the front side of the cylinder 230, the second connection port 218 is located close to the loading / unloading port 224, and the first air inlet 212 is located away from the loading / unloading port 224, so that the first air inlet 212 is located in front of the second connection port 218, that is, the first air inlet 212 is located roughly on the rear side of the entire cabinet assembly 200, the second connection port 218 is located roughly on the front side of the cabinet assembly 200, and the first air inlet 212 is located on the rear side of the cabinet assembly 200. When the radio frequency defrosting device 10 is installed in a refrigerator or other refrigeration equipment, the first air inlet 212 can introduce cold air from the air duct of the refrigerator and use the cold air of the refrigerator to dissipate heat from the electrode plate, the items to be defrosted, and the cylinder 230 inside the cylinder 230.

[0093] Because the first connection port 216 is located on the rear side of the cylinder 230, and the second connection port 218 is located on the front side of the housing assembly 200, gas can enter the placement chamber 214 from the front side of the cylinder 230, flow from front to back within the placement chamber 214, and exit the placement chamber 214 through the first connection port 216 on the rear side. This arrangement can increase the flow time of the gas within the placement chamber 214, increase the heat exchange time with the electrode plate, the item to be thawed, and the surrounding hot gas, thereby improving the heat dissipation effect.

[0094] The second connection port 218 is located at the top of the cylinder 230 and is directly connected to the placement cavity 214. The top cover 260 covers the top of the cylinder 230 and blocks the second connection port 218, which can minimize the electromagnetic waves radiated from the second connection port 218 during the thawing process and reduce the risk of magnetic leakage.

[0095] In some embodiments, along the height direction Z of the housing assembly 200, a first air inlet 212 and a first air outlet 213 are respectively disposed on both sides of the housing assembly 200.

[0096] Since both the first air inlet 212 and the first air outlet 213 are located on the rear side of the housing assembly 200, during the heat dissipation process of the placement cavity 214, external gas enters the placement cavity 214 through the first air inlet 212 and exchanges heat with the electrode plates and other devices in the placement cavity 214. The gas after heat exchange is generally at a relatively high temperature. If it re-enters the placement cavity 214, it will be unable to carry away the heat of the placement cavity 214 because the gas has already reached a high temperature, which will result in poor heat dissipation of the placement cavity 214.

[0097] Along the height direction Z of the enclosure, the first air inlet 212 and the first air outlet 213 are respectively located on both sides of the enclosure assembly 200. For example, the first air inlet 212 can be located on the upper right and the first air outlet 213 can be located on the lower left. This arrangement makes the distance between the first air inlet 212 and the first air outlet 213 relatively large, thereby preventing the gas flowing out from the first air outlet 213 from entering the mounting cavity 223 through the first air inlet 212. It can also improve the heat dissipation effect in the placement cavity 214 to a certain extent.

[0098] Figure 7 It shows Figure 1 A partial cross-sectional schematic diagram of the radio frequency defrosting device 10 in the figure, as shown below. Figure 7 As shown, the flow direction of the gas within the entire placement cavity 214 is as follows: In some embodiments, the radio frequency defrosting device 10 further includes a partition 500, which is disposed in the placement cavity 214 and divides the placement cavity 214 into a radio frequency cavity 2144 and a defrosting cavity 2142; an electrode plate 400 is installed in the radio frequency cavity 2144 and electrically connected to the power amplifier assembly 100; wherein, the housing assembly 200 is provided with a transition port 510 connecting the radio frequency cavity 2144 and the defrosting cavity 2142, and the housing assembly 200 also has a second connection port 218 communicating with the defrosting cavity 2142 and a first connection port 216 communicating with the radio frequency cavity 2144.

[0099] A partition 500 is disposed in the placement cavity 214, dividing the placement cavity 214 into a radio frequency cavity 2144 and a defrosting cavity 2142. The defrosting cavity 2142 is used to hold the items to be defrosted, and an electrode plate 400 is disposed in the radio frequency cavity 2144 to radiate radio frequency defrosting energy to the defrosting cavity 2142, thereby defrosting the items placed in the defrosting cavity 2142.

[0100] In the height direction Z of the housing assembly 200, the defrosting chamber 2142 and the radio frequency chamber 2144 are spaced apart. Either the defrosting chamber 2142 can be positioned above the radio frequency chamber 2144, or vice versa; the specific arrangement is not limited. A partition 500 separates the radio frequency chamber 2144 and the defrosting chamber 2142. When a user removes or places items to be defrosted from the defrosting chamber 2142, the partition 500 can cover the electrode plate 400, preventing it from being exposed. Furthermore, the partition 500 also prevents the items to be defrosted from contacting the electrode plate 400 during the defrosting process, thus avoiding damage to the electrode plate 400.

[0101] During the defrosting process, the electrode plate 400 radiates radio frequency energy into the defrosting chamber 2142 to defrost the item to be defrosted. During this process, the electrode plate 400 generates a significant amount of heat. If this heat is not dissipated in time, it will accumulate on the electrode plate 400, affecting its operation. Therefore, to extend the lifespan of the electrode plate 400, it is necessary to dissipate heat from it promptly.

[0102] In the entire placement cavity 214, gas can enter the defrosting cavity 2142 from the second connection port 218, enter the radio frequency cavity 2144 through the transition port 510 connecting the defrosting cavity 2142 and the radio frequency cavity 2144, and finally exit from the first connection port 216 to the outside of the radio frequency cavity 2144. Of course, gas can also enter through the first connection port 216 and exit through the second connection port 218. Specifically, in some embodiments, gas actually enters the air intake channel 262 from the first air intake port 212, and then enters the defrosting cavity 2142 through the second connection port 218. The gas in the defrosting cavity 2142 enters the radio frequency cavity 2144 through the transition port 510, and finally flows into the air outlet channel 246 through the first connection port 216, and finally exits into the refrigerator's air duct through the first air outlet 213.

[0103] In this process, after entering the defrosting chamber 2142, the gas passes through the transition port 510 into the radio frequency chamber 2144, allowing the gas to flow through the electrode 400 located in the radio frequency chamber 2144. This allows the gas to exchange heat with the electrode 400, carrying away the heat generated by the electrode 400 due to the radiation of radio frequency defrosting energy. This reduces the heat accumulation on the electrode 400, enabling it to dissipate heat in a timely manner. Consequently, it reduces the risk of damage to the electrode 400 due to heat accumulation, thereby improving the service life of the electrode 400.

[0104] In addition, since the gas passes through the thawing chamber 2142 and then the radio frequency chamber 2144 in the entire placement chamber 214, the item to be thawed can be frozen first after thawing is completed, and then the electrode plate 400 can be cooled, so that the item to be thawed can be cooled quickly, which can also improve the user experience to a certain extent.

[0105] It should be noted that in some other embodiments, the first connection port 216 can serve as an air inlet for gas to enter the placement chamber 214 (which is essentially the defrosting chamber 2142). That is, the housing assembly 200 may not include the top cover 260, i.e., it may not include the first air inlet 212 and the air inlet channel 262. The gas directly enters the placement chamber 214 (which is essentially the defrosting chamber 2142) through the first connection port 216.

[0106] Of course, in some other embodiments, the second connection port 216 can serve as the air outlet of the entire placement cavity 214 (which is essentially the radio frequency cavity 2144), that is, the housing assembly 260 may not include the cover 250 and the air outlet channel 246, and the gas in the placement cavity 214 (which is essentially the radio frequency cavity 2144) can be directly discharged through the second connection port 216.

[0107] Since the transition port 510 is located within the housing assembly 200, the transition port 510 can be located on the partition 500, on the housing assembly 200, or between the partition 500 and the housing assembly 200. The location of the transition port 510 is not limited.

[0108] In some embodiments, the housing assembly 200 includes a cylinder 230 and a door 280. The cylinder 230 has a pick-up / placement opening 224, and the door 280 can open or close the pick-up / placement opening 224. The cylinder 230 and the door 280 form a placement cavity 214, and at least one of the cylinder 230 and the door 280 forms a transition opening 510 with the partition 500.

[0109] In this embodiment, the door 280 is rotatably connected to the cylinder 230, allowing the door 280 to open or close the loading / unloading port 224. In other embodiments, the radio frequency defrosting device 10 may also include a drawer 270, with the door 280 and drawer 270 connected to form a drawer assembly. The drawer 270 is tractably connected to the cylinder 230, and the entire drawer assembly allows the door 280 to open or close the loading / unloading port 224 by sliding. When the radio frequency defrosting device 10 has a drawer 270, the item to be defrosted can be placed inside the drawer 270, and the drawer 270 slides into the defrosting chamber 2142, thereby placing the item to be defrosted within the defrosting chamber 2142.

[0110] As for the sliding method of drawer 270, a slide rail can be installed in the defrosting chamber 2142 and fixedly connected to the partition 500, or it can be fixedly connected to the cylinder 230. The specific connection position is not limited.

[0111] In some embodiments, the transition opening 510 may be formed by the partition 500 and the cylinder 230 being spaced apart. Specifically, the partition 500 may be spaced apart from the bottom wall of the cylinder 230 to form the transition opening 510, or it may be spaced apart from the side wall of the cylinder 230 to form the transition opening 510. In addition, the transition opening 510 may also be formed by the partition 500 and the door 280 being spaced apart, or the partition 500 may be fixed inside the cylinder 230 and the transition opening 510 may be directly formed on the partition 500. The specific details are not limited.

[0112] It should be noted that since the radio frequency defrosting device 10 defrosts by radiating radio frequency energy through electromagnetic waves, when the door 280 closes the pick-up and put-out port 224, the space inside the entire cylinder 230 (the entire placement cavity 214) is roughly a shielded cavity. That is, the cylinder 230 and the door 280 have a certain electromagnetic shielding capability, thereby reducing electromagnetic wave radiation to the outside of the placement cavity 214 and reducing magnetic leakage.

[0113] Figure 8 It shows Figure 7 A magnified view of a section at point II, as shown below. Figure 7 As shown, in some embodiments, the partition 500 has a transition groove 520, which forms a transition opening 510 with the cylindrical body 230. The transition groove 520 can be formed on the side of the partition 500 near the radio frequency cavity 2144. The transition groove 520 is a through groove, and the cylindrical body 230 can close the opening of the transition groove 520 to form the transition opening 510. That is, the inner wall of the cylindrical body 230 closes the opening of the transition groove 520 to form the transition opening 510. In other embodiments, the transition opening 510 can also be directly formed on the partition 500, and the specific method is not limited.

[0114] By setting a transition groove 520 on the partition 500, a transition port 510 is formed between the partition 500 and the cylinder 230. Alternatively, a transition port 510 can be directly opened on the partition 500. Regardless of the method, the formation of the transition port 510 is related to the partition 500. This method allows the transition port 510 to be directly opened on the partition 500 without adding other structures to set the transition port 510. This allows the gas in the defrosting chamber 2142 to quickly enter the radio frequency chamber 2144, reduces the resistance to gas flow, and increases the gas flow rate entering the radio frequency chamber 2144. This increases the gas flow rate for heat exchange with the electrode plate 400 and also improves the heat dissipation effect of the electrode plate 400 to a certain extent.

[0115] like Figure 7 and Figure 8 As shown, in some embodiments, the cylinder 230 has a first bottom surface 236 and a second bottom surface 238, with the first bottom surface 236 circumferentially disposed around the second bottom surface 238. Along the height direction Z of the housing assembly 200, the height of the first bottom surface 236 is greater than the height of the second bottom surface 238, and the transition port 510 is located between the first bottom surface 236 and the partition 500.

[0116] The electrode plate 400 can be disposed between the second bottom surface 238 and the partition plate 500. Since the height of the first bottom surface 236 is greater than that of the second bottom surface 238, and conversely, the height of the second bottom surface 238 is less than that of the first bottom surface 236, the second bottom surface 238 is farther from the partition plate 500, resulting in a larger space between the second bottom surface 238 and the partition plate 500. The electrode plate 400 is disposed between the second bottom surface 238 and the partition plate 500, so that there is a certain space between the electrode plate 400 and the partition plate 500, and between the electrode plate 400 and the second bottom surface 238. This allows the gas to pass through the gaps between the electrode plate 400 and the partition plate 500, and between the electrode plate 400 and the second bottom surface 238, respectively. This allows the gas to contact the upper and lower surfaces of the electrode plate 400, thereby increasing the contact area between the gas and the electrode plate 400, increasing the heat exchange between the gas and the electrode plate 400, and thus improving the heat dissipation effect of the electrode plate 400.

[0117] Since the first bottom surface 236 is arranged around the second bottom surface 238, it can be considered that the first bottom surface 236 is located at the edge of the second bottom surface 238. By setting the transition port 510 between the first bottom surface 236 and the partition plate 500, gas can enter the space between the second bottom surface 238 and the partition plate 500 from the edge of the first bottom surface 236. This increases the flow path of gas between the second bottom surface 238 and the partition plate 500, increases the heat exchange between the gas and the electrode plate 400, and thus improves the heat dissipation effect of the electrode plate 400.

[0118] In some embodiments, the cylinder 230 has a guide surface 239, which connects the first bottom surface 236 and the second bottom surface 238. The guide surface 239 is inclined. Since the first bottom surface 236 is higher than the second bottom surface 238, and the transition port 510 is located close to the first bottom surface 236, the inclined arrangement of the guide surface 239 can also guide the gas to the second bottom surface 238, allowing the gas to flow through the gap between the electrode plate 400 and the second bottom surface 238. This allows the gas to flow through the area of ​​the upper surface of the electrode plate 400 (the gap between the electrode plate 400 and the partition plate 500) and the area of ​​the lower surface of the electrode plate 400 (the gap between the electrode plate 400 and the second bottom surface 238), respectively. This allows the gas to contact the upper and lower surfaces of the electrode plate 400, increasing the contact area between the gas and the electrode plate 400, thereby increasing the heat exchange between the gas and the electrode plate 400 and improving the heat dissipation effect of the electrode plate 400.

[0119] As for the fixing method of the partition 500, the partition 500 can be connected to the first bottom surface 236. Specifically, it can be fixed by a snap-fit ​​or by a connector. Specifically, a first connecting hole can be provided on the first bottom surface 236, and a second connecting hole can be provided on the partition 500. The connector passes through the first connecting hole and the second connecting hole to fix the partition 500 to the cylinder 230.

[0120] The number of connectors can be multiple, with each connector arranged around the edge of the partition 500 to improve the fixing effect between the partition 500 and the cylinder 230. It is easy to understand that the number of the first connecting hole, the second connecting hole, and the connectors can be the same.

[0121] Figure 9 It shows Figure 7 A magnified view of a section at point III. Figure 10 A structural schematic diagram of the partition 500 from a first-view perspective is shown. Figure 11 A structural schematic diagram of the partition 500 from a second perspective is shown, as follows. Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments, the first connection port 216 is disposed on the cylinder 230, and the first connection port 216 and the transition port 510 are spaced apart along the depth direction Y of the box assembly 200.

[0122] The above text has already described in detail how the first connection port 216 is connected to the first air outlet 213 (through the air outlet channel 246). As for the connection method between the first connection port 216 and the first air outlet 213, please refer to the previous description, which will not be described again here.

[0123] Along the depth direction Y of the housing assembly 200, the first connection port 216 and the transition port 510 are spaced apart, so that after the gas enters the radio frequency cavity 2144 from the transition port 510, it can have a certain flow path in the radio frequency cavity 2144, increasing the contact time between the gas and the electrode plate 400, thereby improving the heat dissipation effect of the electrode plate 400.

[0124] Of course, in some other embodiments, the first connection port 216 and the transition port 510 can be spaced apart along the width direction X of the housing assembly 200. In any case, it is sufficient to ensure that there is a certain distance between the first connection port 216 and the transition port 510.

[0125] In some embodiments, in the transition port 510 and the first connection port 216, the transition port 510 is located close to the door body 280, and the first connection port 216 is located away from the door body 280.

[0126] The transition port 510 is positioned close to the door 280, while the first connection port 216 is positioned far from the door 280. This means that along the depth direction Y of the housing, the transition port 510 is positioned close to the door 280, while the first connection port 216 is positioned far from the door 280. This arrangement maximizes the distance between the first connection port 216 and the transition port 510 in the depth direction Y of the housing assembly 200. This ensures that the gas can have the longest possible flow path within the radio frequency cavity 2144 after entering from the transition port 510, thereby increasing the contact time between the gas and the electrode plate 400 and improving the heat dissipation effect of the electrode plate 400.

[0127] Since the transition port 510 is located close to the door body 280, the transition port 510 can be spaced apart from the door body 280, so that there is a certain gap between the transition port 510 and the door body 280, which allows the gas in the defrosting chamber 2142 to flow from the gap between the transition port 510 and the door body 280 to the transition port 510, and then enter the radio frequency chamber 2144.

[0128] In other words, the gap between the transition port 510 and the door 280 also serves as a channel for gas to enter the radio frequency cavity 2144. That is, the gap between the transition port 510 and the door 280 forms a transition channel, which connects the radio frequency cavity 2144 and the defrosting cavity 2142, allowing gas to enter the radio frequency cavity 2144 from the defrosting cavity 2141 through the transition channel. The entire transition channel is roughly L-shaped.

[0129] In some embodiments, since the first connection port 216 is also connected to the radio frequency cavity 2144, and the partition 500 separates the defrosting cavity 2142 and the radio frequency cavity 2144, the specific locations of the partition 500 and the first connection port 216 will be described below.

[0130] The cylinder 230 has a rear sidewall opposite to the door 280, and the first connection port 216 is disposed on the rear sidewall. The rear sidewall is the sidewall opposite to the door 280 and also the sidewall opposite to the take-up port 224. That is, the rear sidewall is the rear of the entire cylinder 230 along the depth direction Y of the box. The partition 500 separates the defrosting chamber 2142 and the radio frequency chamber 2144 along the height direction Z of the box assembly 200. Therefore, the projection area of ​​the partition 500 on the rear sidewall along the depth direction Y of the box assembly 200 is relatively small. In order for the partition 500 to cover the first connection port 216 in the radio frequency chamber 2144, the partition 500 may include a partition body 530, a connecting plate 540 and an overlapping part 550. The connecting plate 540 connects the partition body 530 and the overlapping part 550. The connecting plate 540 is spaced apart from the first connection port 216, and the overlapping part 550 is sealed to the rear sidewall.

[0131] Specifically, the partition body 530 is set along the height direction Z of the housing assembly 200, separating most of the space between the radio frequency cavity 2144 and the defrosting cavity 2142. It can be considered that the partition body 530 is the main component of the entire partition 500 that separates the radio frequency cavity 2144 and the defrosting cavity 2142. The partition body 530 is set roughly horizontally. The connecting plate 540 is positioned in front of the rear sidewall and spaced apart from it. The connecting plate 540 is generally vertically positioned so that the gas in the space below the partition 500 (RF cavity 2144) can enter the gap between the connecting plate 540 and the rear sidewall, and then be discharged from the first connection port 216 to the outside of the RF cavity 2144. The overlapping part 550 is used to seal the gap between the connecting plate 540 and the side of the rear sidewall near the defrosting cavity 2142, so that only the gas in the RF cavity 2144 can enter the gap between the connecting plate 540 and the rear sidewall. This ensures that the gas must pass through the RF cavity 2144 before flowing to the first connection port 216, allowing the gas to exchange heat with the electrode plate 400, thereby improving the heat dissipation effect of the electrode plate 400.

[0132] On the other hand, the rear side of the upper half of the rear side wall of the cylinder 230 is convenient for setting an exhaust device that communicates with the first connection port 216. By setting a ventilation space between the connecting plate 540 and the rear side wall, it is convenient to set the first connection port 216 closer to the top.

[0133] In some embodiments, the partition 500 may further include a support portion 560, which is connected to the connecting plate 540 and disposed between the rear sidewall and the connecting plate 540. This arrangement can minimize the risk of the connecting plate 540 blocking the first connection port 216 due to deformation, thus ensuring the air output of the first connection port 216 and thereby ensuring the gas flow rate in the radio frequency cavity 2144, thereby improving the heat dissipation effect of the electrode plate 400.

[0134] In some embodiments, along the height direction Z of the housing assembly 200, the overlapping portion 550 and the partition body 530 are respectively disposed at both ends of the connecting plate 540. Since the radio frequency cavity 2144 is disposed below the defrosting cavity 2142, that is, the partition 500 is below the overlapping portion 550, the overlapping portion 550 is used to seal the gap between the connecting plate 540 and the rear sidewall near the defrosting cavity 2142, so that the gas must pass through the radio frequency cavity 2144 before it can flow to the first connection port 216, so that the gas can exchange heat with the electrode plate 400, thereby improving the heat dissipation effect of the electrode plate 400.

[0135] As can be seen from the above, within cylinder 230 (gas flow direction as follows) Figure 6(As indicated by the hollow arrow), gas enters the air intake channel 262 through the first air inlet 212, then enters the defrosting chamber 2142 through the second connection port 218, flows through the gap between the drawer 270 and the inner wall of the cylinder 230 to the radio frequency cavity 2144, enters the radio frequency cavity 2144 through the transition port 510, then enters the air outlet channel 246 through the first connection port 216, and finally flows into the refrigerator's air duct through the first air outlet 213. In summary, the radio frequency defrosting device 10 provided in this embodiment has two independent air paths for the placement cavity 214 and the mounting cavity 223, allowing the gas entering the placement cavity 214 to be directly discharged outside the cabinet assembly 200. This arrangement reduces the impact of the power amplifier assembly 100 on the gas flow path within the placement cavity 214, increases the amount of gas entering the placement cavity 214, and also improves the heat dissipation effect within the placement cavity 214 to a certain extent.

[0136] Figure 12 This illustration shows a third-view structural schematic diagram of the radio frequency defrosting device provided in an embodiment of this application. Figure 13 This diagram shows a second explosion view of the structure of the radio frequency defrosting device provided in an embodiment of this application. Figure 14 This illustration shows a structural schematic diagram of the radio frequency defrosting device provided in an embodiment of this application from a third explosion perspective, as shown below. Figure 12 , Figure 13 and Figure 14 As shown, in some embodiments, the enclosure assembly 200 further includes a second air inlet 221 and a second air outlet 222, both of which are connected to the mounting cavity 223. Gas enters the mounting cavity 223 from the second air inlet 221 and then flows out of the mounting cavity 223 from the second air outlet 222. The placement cavity 214 and the mounting cavity 223 are two independent air paths. The heat dissipation of the power amplifier assembly 100 and the heat dissipation inside the placement cavity 214 are independent of each other, which can reduce the influence between the inside of the placement cavity 214 and the power amplifier assembly 100, thereby improving the heat dissipation effect of the power amplifier assembly 100 and the inside of the placement cavity 214.

[0137] It is easy to understand that this arrangement can be considered as two parallel cavities, namely the placement cavity 214 and the mounting cavity 223. Compared with the arrangement where the mounting cavity 223 is connected to the placement cavity 214, more gas can enter the mounting cavity 223 and more gas can exchange heat with the power amplifier component 100, thereby improving the heat dissipation effect of the power amplifier component 100.

[0138] Furthermore, in related technologies, since the placement cavity 214 is connected to the mounting cavity 223, the gas enters the placement cavity 214 and then passes through the mounting cavity 223 before finally being discharged outside the housing assembly 200. Because the power amplifier assembly 100 is relatively small, in order not to increase the overall volume of the RF defrosting device 10, the mounting cavity 223 is also relatively small, meaning the gap between the power amplifier assembly 100 and the inner wall of the mounting cavity 223 is small. This results in greater resistance when the gas passes through the mounting cavity 223, leading to a smaller amount of gas entering the placement cavity 214. Additionally, because the placement cavity 214 releases a significant amount of heat during the defrosting process, this design prevents timely heat dissipation within the placement cavity 214, causing a large accumulation of heat inside. In severe cases, this can lead to the burnout of the electrode plate 400. In this embodiment, the placement cavity 214 and the mounting cavity 223 are two independent air paths, which allows the gas entering the placement cavity 214 to be directly discharged to the outside of the enclosure assembly 200. This arrangement can reduce the influence of the power amplifier assembly 100 on the gas flow path in the placement cavity 214, increase the amount of gas entering the placement cavity 214, and also improve the heat dissipation effect in the placement cavity 214 to a certain extent.

[0139] Since the placement cavity 214 is used to hold the items to be thawed, the placement cavity 214 is set as large as possible. During the thawing process, a lot of heat is generated in the placement cavity 214. In order to improve the heat dissipation effect, the first air inlet 212 and the first air outlet 213 can also be set to be large to increase the gas flow rate into the placement cavity 214, thereby increasing the heat exchange and improving the heat dissipation effect.

[0140] In some embodiments, the enclosure assembly 200 also has a loading / unloading port 224 communicating with the placement cavity 214, through which a user can retrieve or place items to be thawed. The amplifier assembly 100 is located on the side away from the loading / unloading port 224. The enclosure assembly 200 is generally cuboid. For ease of description, the enclosure assembly 200 is defined to have a height direction Z, a width direction X, and a depth direction Y. The height direction Z is the vertical direction of the enclosure in its use state, with the upper part of the vertical direction being called "up" and the lower part being called "down". The depth direction Y is the direction from the loading / unloading port 224 to the amplifier assembly 100, with one side of the loading / unloading port 224 designated as "front" and the other side of the amplifier assembly 100 designated as "rear". The width direction X is perpendicular to both the height direction Z and the depth direction Y, with the left side of the loading / unloading port 224 facing the amplifier assembly 100 designated as "left" and the right side as "right".

[0141] As for the positions of the first air inlet 212, the first air outlet 213, the second air inlet 221, and the second air outlet 222, since the loading and unloading port 224 is located on the front side of the housing assembly 200, the first air inlet 212, the first air outlet 213, the second air inlet 221, and the second air outlet 222 can be located on the rear side of the housing assembly 200, or on the upper or lower side of the housing assembly 200, or on the left or right side of the housing assembly 200. The specific positions are not limited, as long as the first air inlet 212 and the first air outlet 213 are connected to the placement cavity 214, and the second air inlet 221 and the second air outlet 222 are connected to the mounting cavity 223.

[0142] When the radio frequency defrosting device 10 is applied to electrical equipment 1, especially to refrigeration equipment such as refrigerators and freezers, the radio frequency defrosting device 10 can use the cold air in the refrigeration equipment for heat dissipation. Then the first air inlet 212 and the second air inlet 221 can be connected to the air duct of the refrigeration equipment, so that the cold air can enter the placement cavity 214 and the installation cavity 223 respectively. In this case, the first air inlet 212 and the second air inlet 221 can be set on the rear side of the cabinet assembly 200 for easy connection with the air duct of the refrigeration equipment.

[0143] In some embodiments, the housing assembly 200 includes a cover 240 and a cylinder 230. The cover 240 is connected to one side of the cylinder 230. A mounting cavity 223 is disposed within the cover 240, a placement cavity 214 is disposed within the cylinder 230, and a second air inlet 221 and a second air outlet 222 are disposed on the cover 240. The housing assembly 200 may include a drawer 270 and a cylinder 230, which are slidably connected. The drawer 270 can place items to be defrosted within the cylinder 230 (within the placement cavity 214), and a loading / unloading opening 224 is disposed on the cylinder 230.

[0144] The loading / unloading port 224 is located on the front of the cylinder 230, while the cover 240 is located on the rear of the cylinder 230. The mounting cavity 223 is located inside the cover 240, meaning the amplifier assembly 100 is located on the rear of the cylinder 230. Because the loading / unloading port 224 is located on the front of the cylinder 230, placing the amplifier assembly 100 on the rear of the cylinder 230 minimizes the space occupied by the amplifier assembly 100 on the front of the cylinder 230, allowing the loading / unloading port 224 to be as large as possible. This facilitates the user's handling of items to be thawed, making operation easier.

[0145] The second air inlet 221 and the second air outlet 222 are provided on the cover 240, so that the gas can directly enter the mounting cavity 223, reducing the gas flow path, thereby reducing the gas flow resistance to a certain extent, and also increasing the amount of gas entering the mounting cavity 223 to a certain extent.

[0146] In some embodiments, the cover 240 includes a rear cover 242 and a cover plate 244 disposed away from the pick-up port 224. The rear cover 242 and the cylinder 230 are connected to form an installation cavity 223. The second air inlet 221 and the second air outlet 222 are disposed on different sides of the rear cover 242.

[0147] The second air inlet 221 is located on the rear side of the rear cover 242, and the second air outlet 222 can be located on the upper side, lower side, left side, right side, etc. of the rear cover 242.

[0148] During the heat dissipation process of the power amplifier component 100, external gas enters the mounting cavity 223 through the second air inlet 221 and exchanges heat with the power amplifier component 100 in the mounting cavity 223. The gas after heat exchange is generally at a relatively high temperature. If it re-enters the mounting cavity 223, it will be unable to carry away the heat of the power amplifier component 100 because the gas has reached a high temperature, which will result in poor heat dissipation of the power amplifier component 100.

[0149] Since the second air inlet 221 and the second air outlet 222 are located on different sides of the rear cover 242, the gas flow directions of the second air inlet 221 and the second air outlet 222 are different. This can prevent the gas flowing out from the second air outlet 222 from entering the mounting cavity 223 from the second air inlet 221, and can also improve the heat dissipation effect of the power amplifier assembly 100 to a certain extent.

[0150] In some embodiments, the rear cover 242 includes a rear plate 2422 and a plurality of mounting plates 2424, the mounting plates 2424 connecting the rear plate 2422 and the cover plate 244, a second air inlet 221 being disposed on the rear plate 2422, and a second air outlet 222 being disposed on the mounting plate 2424.

[0151] The rear plate 2422 is roughly parallel to the cover plate 244 and is spaced apart along the depth direction Y of the enclosure. The mounting plate 2424 connects the rear plate 2422 and the cover plate 244. The second air inlet 221 is located on the rear plate 2422, so that the gas flow direction of the second air inlet 221 is roughly aligned with the depth direction Y of the enclosure. Since the second air outlet 222 is located on the mounting plate 2424, the gas flow direction of the second air outlet 222 is roughly perpendicular to the depth direction Y of the enclosure. Thus, the gas flow direction of the second air inlet 221 and the gas flow direction of the second air outlet 222 are roughly perpendicular, making the gas flow directions of the second air inlet 221 and the second air outlet 222 completely different. This can prevent the gas blown out from the second air outlet 222 from re-entering the mounting cavity 223 as much as possible, and can also improve the heat dissipation effect of the power amplifier assembly 100 to a certain extent.

[0152] In addition, the second air inlet 221 is located on the rear plate 2422 and the second air outlet 222 is located on the mounting plate 2424. This arrangement also allows for a certain distance between the second air inlet 221 and the second air outlet 222, which can prevent the gas blown out from the second air outlet 222 from re-entering the mounting cavity 223 and can also improve the heat dissipation effect of the power amplifier assembly 100 to a certain extent.

[0153] In some embodiments, multiple second air outlets 222 are provided, and these multiple second air outlets 222 are respectively disposed on different sides of the rear cover 242. Multiple mounting plates 2424 are also provided, and these multiple mounting plates 2424 are respectively connected to the upper, lower, left, and right sides of the rear plate 2422 and the cover plate 244. The multiple second air outlets 222 can be disposed on different mounting plates 2424, allowing the multiple second air outlets 222 to blow air towards the cover 240 in different ways. This ensures that the gas blown from the mounting cavity 223 can be directed to different areas, preventing hot air from accumulating in the same area.

[0154] In some embodiments, the rear cover 242 may further include a bottom frame 245, which is connected to the lower part of the rear plate 2422 and may also be connected to the cylinder 230.

[0155] Figure 15 A schematic diagram of the power amplifier assembly is shown. Figure 16 An exploded view of the power amplifier assembly from a first-person perspective is shown. Figure 7 An exploded view of the power amplifier assembly from a second perspective is shown, such as... Figure 15 , Figure 16 and Figure 17 As shown, in some embodiments, the power amplifier assembly 100 includes a housing 110, a power amplifier component 120, and a heat sink 130. The heat sink 130 and the power amplifier component 120 are mounted on the housing 110. The heat sink 130 has a heat dissipation channel 132, which is connected to a second air inlet 221 and a second air outlet 222.

[0156] A heat sink 130 is provided on the housing 110 of the power amplifier assembly 100. The heat sink 130 can accelerate the heat dissipation of the power amplifier assembly 120 and improve the heat dissipation effect of the power amplifier assembly 120. The housing 110 has a receiving cavity 112. The power amplifier assembly 120 can be disposed in the receiving cavity 112 of the housing 110, and the heat sink 130 can be disposed outside the housing 110 (disposed of in the receiving cavity 112).

[0157] The housing 110 is the basic component of the entire power amplifier assembly 100. The housing 110 provides a base for the installation of components such as the power amplifier 120 and the heat sink 130. The power amplifier 120 is located inside the housing 110. The housing 110 can protect the power amplifier 120 and reduce the impact of dust and other impurities on the power amplifier 120.

[0158] The power amplifier 120 amplifies the radio frequency (RF) signal, enabling it to output with greater energy. This allows the electrode plate 400 to radiate RF defrosting energy to defrost the items. During operation, the power amplifier 120 generates heat due to the amplification of the RF signal. Failure to dissipate heat promptly can affect its lifespan. The heat sink 130 is mounted on the housing 110. Heat generated inside the housing 110 radiates to the housing 110, and because the heat sink 130 is installed on the housing 110, the radiated heat is dissipated through it. This allows the heat inside the housing 110 to dissipate quickly, minimizing heat buildup and maintaining the power amplifier 120 within a suitable temperature range. This ensures the power amplifier 120 functions properly and extends its lifespan. Because it can dissipate heat in time, the power amplifier 120 can also ensure the amplification factor of the radio frequency defrosting signal, so that the electrode plate 400 can radiate sufficient radio frequency defrosting energy, which can improve the defrosting effect to a certain extent.

[0159] Since the heat sink 130 is mounted on the housing 110, the heat radiated to the housing 110 can be directly transferred to the heat sink 130, which reduces the thermal resistance between the housing 110 and the heat sink 130. This allows the heat to be quickly transferred to the heat sink 130 and dissipated through it. This arrangement improves the heat dissipation speed and quickly dissipates the heat inside the housing 110 to the outside of the housing 110, keeping the power amplifier 120 within a suitable temperature range, ensuring that the power amplifier 120 can work normally, and thus extending the service life of the power amplifier 120.

[0160] In some embodiments, the housing 110 includes a box body 113 and a box cover 114, which are connected. A heat sink 130 is disposed on the side of the box body 113 away from the box cover 114. The heat sink 130 is disposed on the box body 113 and can be separately formed from or integrally formed with the box body 113. In both the box body 113 and the box cover 114, the power amplifier 120 is disposed close to the box body 113, making the distance between the power amplifier 120 and the box body 113 relatively small. By placing the heat sink 130 on the box body 113, the distance between the heat sink 130 and the power amplifier 120 can be minimized, thereby accelerating heat conduction and improving heat dissipation speed.

[0161] In some embodiments, the heat sink 130 includes a plurality of heat sinks 131, which are spaced apart on the housing 110.

[0162] Multiple heat sinks 131 are spaced apart on the housing 110, forming a heat dissipation channel 132 between adjacent heat sinks 131 (e.g., Figure 5 As shown, when the gas passes through the heat dissipation channel 132, it can carry away the heat on the heat sink 131, which can improve the heat dissipation speed to a certain extent.

[0163] The extension direction of multiple heat sinks 131 can be the same, so that the direction of the multiple heat dissipation channels 132 formed is also the same, thereby making the airflow of the multiple heat dissipation channels 132 approximately the same, and making the heat dissipation of heat sinks 131 located in different heat dissipation channels 132 approximately the same, thereby enabling the entire heat dissipation component 130 to dissipate heat evenly within the housing 110, minimizing the situation of excessive local heat in the power amplifier component 120 due to uneven heat dissipation.

[0164] The heat dissipation channel 132 is connected to the second air inlet 221 and the second air outlet 222, so that the gas can enter the mounting cavity 223 from the second air inlet 221 and then enter the heat dissipation channel 132 to exchange heat with the heat sinks 131 on both sides of the heat dissipation channel 132, reduce wind resistance, and allow more gas to enter the heat dissipation channel 132, thereby increasing the heat exchange with the heat sink 130 and improving the heat dissipation effect.

[0165] In some embodiments, the power amplifier assembly 100 further includes a cooling fan 140, which is mounted on the housing 110 and / or the heat sink 130, and is configured to correspond to the second air inlet 221.

[0166] In some embodiments, the cooling fan 140 is mounted on the heat sink 130 and / or the housing 110. Since the cooling fan 140 is also located outside the housing 110, the closer the cooling fan 140 is to the heat sink 130, the more gas will accumulate in the heat dissipation channel 132. Mounting the cooling fan 140 on the heat sink 130 and / or the housing 110 allows the cooling fan 140 to be as close as possible to the heat dissipation channel 132, enabling more gas to flow into the heat dissipation channel 132 and increasing the gas flow rate in the heat dissipation channel 132.

[0167] It should be noted that the cooling fan 140 being installed on the heat sink 130 and / or the housing 110 means that the cooling fan 140 can be installed only on the heat sink 130, that is, the cooling fan 140 is connected to the heat sink 130; or the cooling fan 140 can be installed only on the housing 110, that is, the cooling fan 140 is only connected to the housing 110; or the cooling fan 140 can be installed on both the heat sink 130 and the housing 110, that is, the cooling fan 140 is connected to both the housing 110 and the heat sink.

[0168] Since the heat sink 130 is mounted on the housing 110, and the cooling fan 140 is also mounted on the housing 110, it can be said that the cooling fan 140 is close to the heat sink 130, that is, the cooling fan 140 is close to the heat dissipation channel 132, which allows more gas to flow to the heat dissipation channel 132 and increases the gas flow rate in the heat dissipation channel 132.

[0169] Regarding the specific detachable installation method, a first fixing part 118 can be provided on the housing 110 and / or the heat sink 130, and a second fixing part 142 can be provided on the cooling fan 140. The first fixing part 118 and the second fixing part 142 can be detachably connected. The first fixing part 118 and the second fixing part 142 can be snapped together, or a first fixing hole can be provided on the first fixing part 118, and a second fixing hole can be provided on the second fixing part 142. A fixing member 150 can be passed through the first fixing hole and the second fixing hole to fix the cooling fan 140 to the housing 110 and / or the first heat sink 134.

[0170] The cooling fan 140 is positioned corresponding to the second air inlet 221, so that the gas outside the mounting cavity 223 can enter the mounting cavity 223 under the action of the cooling fan 140, increasing the amount of gas entering the mounting cavity 223, which can also improve the heat dissipation effect to a certain extent.

[0171] The cooling fan 140 can be a centrifugal fan, which allows gas to enter from the axial direction of the cooling fan 140 and flow out from the radial direction of the cooling fan 140. This configuration can also be adapted to the gas flow direction of the second air inlet and the second air outlet, thereby improving the heat dissipation effect.

Figure 18 As shown, based on the same inventive concept, this application also provides an electrical device 1, which includes a main body 20 and the aforementioned radio frequency defrosting device 10, with the radio frequency defrosting device 10 installed on the main body 20.
