[0050] Example

[0051] Please refer to Figure 1 This embodiment provides a transformer 300 and an air cooling module 100 applied to the transformer 300. The air cooling module 100 can achieve heat exchange inside the transformer 300 while the transformer 300 is sealed, thereby preventing the inside of the transformer 300 from being affected by salt mist and humid air, and reducing the cost and size of the transformer 300.

[0052] In this embodiment, the transformer 300 includes a transformer body 310 and an air cooling module 100. An air duct 311 is provided in the transformer body 310. The air cooling module 100 is installed in the transformer body 310. The air cooling module 100 can circulate the air in the air duct 311 and achieve heat dissipation with the external environment.

[0053] Please refer to Figures 1 to 4 In this embodiment, the air cooling module 100 includes a mounting body 110, a first fan 130, a second fan 140 and a heat conductor 150. The mounting body 110 has an independent first air duct 111 and a second air duct 112. The heat conductor 150 is mounted on the mounting body 110, and is partially located in the first air duct 111, and the other part is located in the second air duct 112. The first fan 130 is mounted on the first air duct 111, and the first air duct 111 has a first inlet 113 and a first outlet 114. When the first fan 130 is running, air can flow from the first inlet 113 into the first air duct 111, and then be sent out from the first outlet 114 after passing through the heat conductor 150. The second fan 140 is installed in the second air duct 112, and the second air duct 112 has a second inlet 115 and a second outlet 116. When the second fan 140 is running, the wind can flow into the second air duct 112 from the second inlet 115, and then be sent out from the first outlet 114 after passing through the heat conductive member 150. The mounting body 110 is installed on the transformer body 310, and the first inlet 113 and the first outlet 114 are respectively connected to the two ends of the air duct 311 to form a "U"-shaped flow channel. The formed "U"-shaped flow channel is sealed and will not convect with the outside air.

[0054] In this embodiment, the first air duct 111 and the second air duct 112 are independently arranged on the installation body 110 of the air cooling module 100, and the heat conducting member 150 is arranged between the first air duct 111 and the second air duct 112. After the air cooling module 100 is installed on the transformer body 310, the first air duct 111 can form a sealed flow channel in the shape of a Chinese character "U" with the air duct 311 of the transformer body 310, so that the sealing of the transformer 300 is not affected, and the inside of the transformer 300 is not affected by salt spray and external humid air. When performing thermal management, the first fan 130 and the second fan 140 are turned on, and the first fan 130 can make the air circulation of the sealed air duct 311 in the shape of a Chinese character "U" take away the heat of the transformer body 310, and exchange heat with the heat conducting member 150 when passing through the heat conducting member 150, so that the temperature of the air in the sealed flow channel in the shape of a Chinese character "U" can be reduced, and the cooling of the transformer 300 is achieved. The heat absorbed by the heat conductive member 150 located in the first air duct 111 can be conducted along the heat conductive member 150 to one end of the heat conductive member 150 located in the second air duct 112, and the operation of the second fan 140 can inhale the external cold air, and discharge it to the external air after cooling the heat conductive member 150, thereby transferring the heat to the external air. Overall, the air cooling module 100 is used to achieve air cooling and heat dissipation inside the transformer 300 in a sealed state, and the structure is simple, the cost is low, and the volume is smaller than that of liquid cooling heat exchange.

[0055] It should be noted that the “U”-shaped air duct defined in this embodiment is to better indicate that the air duct 311 and the first air duct 111 form a closed circulation air duct, and the air duct 311 is not limited to having only one flow path, and may also be a plurality of parallel air ducts. The air duct 311 provided in the transformer body 310 may be provided according to the heat source in the transformer body 310, so that the air can achieve more heat exchange during the flow process, for example, the air duct 311 may be provided according to the position and number of the windings in the transformer body 310.

[0056] Please refer to Figures 2 to 4 In this embodiment, the heat conducting member 150 is a heat pipe assembly 151 , one end of the evaporation side of the heat pipe assembly 151 is located in the first air duct 111 , and one end of the condensation side of the heat pipe assembly 151 is located in the second air duct 112 .

[0057] In this embodiment, the heat conductor 150 is set as a heat pipe assembly 151. Since the heat pipe 153 is an efficient heat transfer element, its working principle is based on the phase change cycle of the working fluid inside the heat pipe 153 to achieve rapid heat transfer. Specifically, the heat exchange principle of the heat pipe 153 can be summarized as the following steps: 1. Evaporation stage: One end of the heat pipe 153 is the evaporation end, which is usually located near the heat source. When the heat source heats the evaporation end of the heat pipe 153, the working fluid filled inside the heat pipe 153 (usually a low-boiling point liquid, such as mercury, water or ammonia) absorbs heat and evaporates into gas. This process is accompanied by a phase change from liquid to gas, absorbing a large amount of latent heat. 2. Heat conduction and convection: The formed steam begins to move toward the cold end inside the heat pipe 153 due to its low density. The inside of the heat pipe 153 is usually in a high vacuum state to reduce the heat loss of the steam during the movement process and ensure efficient heat conduction. Steam flows rapidly in the heat pipe 153, transferring heat from the evaporation end to the condensation end through heat conduction of the wall of the heat pipe 153 and convection of the steam itself. 3. Condensation stage: When the steam reaches the condensation end (usually in contact with the cold source or the ambient temperature is low), it releases the latent heat absorbed during the evaporation process, and the steam condenses back into liquid during this process. The heat released in this process is absorbed by the cold source or dissipated through the heat dissipation facilities at the condensation end. 4. Reflux stage: The liquid working fluid refluxes to the evaporation end under the action of gravity or with the help of the capillary force of the capillary structure (such as a porous core), and in some cases, through the auxiliary gravity or pump action. The capillary structure is designed to help the working fluid overcome gravity or other resistance, ensuring that the liquid working fluid can continuously return to the evaporation section to complete the cycle. 5. Continuous cycle: This process repeats itself to form a closed thermal cycle system that continuously transfers heat from the heat source to the cold source. The high efficiency of heat pipes lies in their rapid phase change process and heat transfer with almost no energy loss, making them an efficient and reliable heat management technology that is widely used in many fields such as electronic equipment cooling, spacecraft thermal control, solar energy collection, and building air conditioning systems.

[0058] Furthermore, the mounting body 110 has a cavity 117, and a partition 118 is provided in the cavity 117. The partition 118 divides the cavity 117 into a first air duct 111 and a second air duct 112 that are independent of each other. The heat pipe assembly 151 includes a plurality of heat pipes 153, and the partition 118 is provided with a plurality of connecting holes 119. The plurality of heat pipes 153 are plugged into the plurality of connecting holes 119 one by one to form the heat pipe assembly 151. One end of the evaporation side of the heat pipe 153 is located in the first air duct 111, and one end of the condensation side of the heat pipe 153 is located in the second air duct 112.

[0059] In this embodiment, the partition plate 118 is provided with a connecting hole 119 to install the heat pipe 153, which makes the installation easier.

[0060] Please refer to Figures 2 to 4 In this embodiment, the heat pipe assembly 151 further includes a plurality of heat conducting sheets 155 . The heat conducting sheets 155 are provided with fixing holes 157 , and the plurality of heat conducting sheets 155 are all mounted on the heat pipe 153 through the fixing holes 157 .

[0061] In this embodiment, a plurality of spaced heat conducting plates 155 are provided at both the evaporation end and the condensation end of the heat pipe 153, so that the heat exchange area of ​​the heat pipe assembly 151 can be increased, thereby being more conducive to heat exchange in an air-cooling manner.

[0062] In this embodiment, the mounting body 110 includes a first side panel 121, a second side panel 122, a third side panel 123 and a fourth side panel 124. The first side panel 121 and the second side panel 122 are arranged opposite to each other, and the third side panel 123 and the fourth side panel 124 are arranged opposite to each other, and both are connected to the first side panel 121 and the second side panel 122. The partition 118 is arranged between the first side panel 121 and the second side panel 122, and the two sides are connected to the third side panel 123 and the fourth side panel 124 respectively. The first air duct 111 is formed between the first side panel 121 and the partition 118. The second air duct 112 is formed between the second side panel 122 and the partition 118. The mounting body 110 is formed by splicing a plurality of side panels, so the structure is simple.

[0063] Please refer to Figures 2 to 4 In this embodiment, the first inlet 113 and the first outlet 114 are arranged on both sides of the length direction of the first side plate 121, and the heat pipe 153 is located between the first inlet 113 and the first outlet 114. The first end plate 125 and the second end plate 126 are respectively arranged at both ends of the first air duct 111. The first fan 130 is a centrifugal fan, and the axial direction of the first fan 130 is arranged corresponding to the first inlet 113. The first air inlet and the first outlet 114 are arranged on the same side, so that they are conveniently connected to the air duct 311 of the transformer body 310.

[0064] In this embodiment, the length of the first side plate 121 and the partition plate 118 is greater than the length of the second side plate 122, so that the length of the first air duct 111 is greater than the length of the second air duct 112 and a motor installation position 127 is formed on a side of the second air duct 112 close to the first inlet 113. An installation notch 128 is provided on the partition plate 118 corresponding to the first inlet 113. The first fan 130 is installed on the partition plate 118, and the blades of the first fan 130 extend into the first air duct 111 through the installation notch 128.

[0065] Since the length of the circulation channel formed by the first air duct 111 and the internal air duct 311 of the transformer body 310 is relatively long and has relatively large wind resistance, a relatively large first fan 130 is required. In this example, the second air duct 112 is arranged to be shorter, so that a corresponding installation position of the first fan 130 can be reserved on one side of the first air duct 111, so that the volume of the air cooling module 100 can be reduced, and the shortened second flow channel is shorter and has smaller fluid resistance, so that a low-power second fan 140 can be selected to allow cold air in the external environment to flow and meet the heat exchange requirements.

[0066] In this embodiment, a third end plate 129 is disposed on one side of the second air duct 112 close to the first fan 130. The second inlet 115 is disposed on the second side plate 122, and the second fan 140 is a centrifugal fan, which is installed on the second side plate 122 and located in the second air duct 112.

[0067] Please refer to Figures 2 to 4 In this embodiment, the second inlet 115 is arranged on the second side plate 122, so that the length of the flow channel can be shortened while facilitating the installation of the centrifugal fan.

[0068] In an optional embodiment, the second outlet 116 is disposed on a side of the second air duct 112 away from the third end plate 129 .

[0069] In this embodiment, the second outlet 116 is disposed on the opposite side of the third end plate 129, so that a straight outlet is adopted, so that the flow resistance of the second air duct 112 is smaller.

[0070] Secondly, the air cooling module 100 provided in this embodiment is also used for air cooling and heat dissipation of other equipment.

[0071] In summary, the working principles and beneficial effects of the air cooling module 100 and the transformer 300 provided by the embodiment of the utility model include:

[0072] The present application sets a mutually independent first air duct 111 and a second air duct 112 on the mounting body 110 of the air cooling module 100, and sets a heat conducting member 150 between the first air duct 111 and the second air duct 112. After the air cooling module 100 is mounted on the transformer body 310, the first air duct 111 can form a "U"-shaped sealed air duct 311 with the air duct 311 of the transformer body 310, which will not affect the sealing of the transformer 300, and the inside of the transformer 300 will not be affected by salt spray and external humid air. When performing thermal management, the first fan 130 and the second fan 140 are turned on, and the first fan 130 can make the air circulation of the "U"-shaped sealed air duct 311 carry the heat of the transformer body 310, and exchange heat with the heat conducting member 150 when passing through the heat conducting member 150, so that the temperature of the air in the "U"-shaped sealed flow channel can be reduced to achieve cooling of the transformer 300. The heat absorbed by the heat conductor 150 can be conducted along the heat conductor 150 to one end of the heat conductor 150 located at the second air duct 112, and the operation of the second fan 140 can inhale the external cold air, and discharge it to the external air after cooling the heat conductor 150, thereby transferring the heat to the external air. Overall, the air cooling module 100 is used to achieve air cooling and heat dissipation inside the transformer 300 in a sealed state, and has a simple structure, low cost, and a smaller volume than liquid cooling heat exchange.
