Description

Tank heat dissipation assembly

[0001] The present invention relates to a tank heat dissipation assembly, and more particularly, to a tank heat dissipation assembly having a structure that can effectively cool heat generated during operation while also reinforcing durability against vibrations generated along with the heat.

[0002] A transformer is a device that receives power from an external source, adjusts its frequency or voltage, and then re-distributes it. As power demand increases, transformers are widely used to minimize transmission losses and convert the received power into a form usable at the point of demand.

[0003] Transformers are typically energized by high-voltage currents. That is, they can operate by stepping down high-voltage currents to low-voltage currents or by stepping up low-voltage currents to high-voltage currents. Therefore, leaving transformers exposed to the elements poses a safety risk. Therefore, transformers are typically housed in enclosures, such as tanks, filled with insulating materials.

[0004] Meanwhile, as transformers continue to operate, a significant amount of heat is generated. If this heat remains in the transformer, individual components of the transformer are at risk of thermal damage. Therefore, a structure capable of quickly cooling the heat generated in the transformer is required.

[0005] Referring to FIGS. 14 and 15, a tank heat dissipation assembly (1000) provided in a transformer according to the prior art is illustrated. The tank heat dissipation assembly (1000) is configured to include a tank member (1100) for accommodating a transformer and a heat dissipation member (1200) coupled with the tank member (1100) for dissipating heat.

[0006] In the illustrated example, the heat dissipation member (1200) is provided as a pair, including a first heat dissipation member (1200a) and a second heat dissipation member (1200b). Each of the pair of heat dissipation members (1200a, 1200b) includes a coupling member (1210) for coupling with the tank member (1100). At this time, in order to improve heat dissipation efficiency, the pair of heat dissipation members (1200a, 1200b) are spaced apart from each other by a separation space (1300). That is, the pair of heat dissipation members (1200a, 1200b) are coupled to the tank member (1100) independently of each other.

[0007] When the transformer is operated and the tank member (1100) vibrates, each heat dissipation member (1200a, 1200b) begins to vibrate. Accordingly, high stress is generated at the portion where the heat dissipation member (1200a, 1200b) and the tank member (1100) are joined.

[0008] If the above condition persists, there is a risk that the joint portion of the heat dissipation member (1200) and the tank member (1100) will be damaged by stress fatigue, and the heat dissipation member (1200) and the tank member (1100) will be separated arbitrarily.

[0009] Accordingly, a method is required to effectively cool the heat generated from the transformer while also enhancing the durability against vibrations generated during transformer operation.

[0010] Korean Patent Document No. 10-1669903 discloses a cooling device for a transformer tank. Specifically, the device includes a first cooling unit connected to the internal space of the transformer tank and a second cooling unit connected to the surface of the transformer tank, and capable of cooling the transformer tank in various ways.

[0011] However, the cooling device for a transformer tank disclosed in the above-mentioned prior art document requires that at least some of the components be located inside the transformer tank. In other words, the above-mentioned prior art document does not provide a method for effectively cooling a transformer tank without excessive structural changes to the transformer tank.

[0012] Korean Patent Document No. 10-2537971 discloses a sealed expansion tank and an automatic pressure control type transformer water cooling system. Specifically, the disclosed system comprises a sealed expansion tank capable of cooling a transformer and an automatic pressure control type transformer water cooling system, including a plurality of sealed expansion tanks that operate separate water circulation pumps to supply water circulating in a sealed transformer cooling water system to a cooling tower.

[0013] However, the sealed expansion tank and automatic pressure control transformer water cooling system disclosed in the above-mentioned prior art document do not disclose specific coupling relationships between each component. That is, the above-mentioned prior art document only provides the connection relationship between multiple sealed expansion tanks and a transformer at the conceptual stage, and does not disclose the structural coupling relationship.

[0014] Furthermore, the above-mentioned prior documents do not provide a method to prevent the configuration provided for cooling the transformer tank from being damaged by vibrations generated during operation of the transformer.

[0015] The present invention is intended to solve the above problems, and an object of the present invention is to provide a tank heat dissipation assembly having a structure capable of effectively cooling heat generated in a transformer.

[0016] Another object of the present invention is to provide a tank heat dissipation assembly having a structure that can improve coupling strength with a transformer.

[0017] Another object of the present invention is to provide a tank heat dissipation assembly having a structure that can prevent damage caused by vibrations generated in a transformer.

[0018] Another object of the present invention is to provide a tank heat dissipation assembly having a structure capable of preventing damage caused by vibrations generated in a transformer while minimizing structural changes.

[0055] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily practice the present invention. The present invention may be implemented in various different forms and is not limited to the embodiments described herein. To clearly explain the present invention, parts irrelevant to the description are omitted in the drawings, and the same reference numerals designate identical or similar components throughout the specification.

[0057] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings correspond to a preferred embodiment of the present invention, and do not represent all of the technical ideas of the present invention, so there may be various equivalents and modified examples that can replace the configuration at the time of filing of the present invention.

[0058] In the following description, descriptions of some components may be omitted to clarify the features of the present invention.

[0059] The term "fluid communication" as used herein refers to one or more elements being fluidly connected to one another. In one embodiment, the fluid communication may be formed by elements such as conduits, pipes, or piping. In the following description, the fluid communication may be used in the same sense as one or more elements being "fluidly connected" to one another.

[0060] The term "conduction" as used herein refers to the connection of one or more elements to enable the transmission of current or electrical signals. In one embodiment, the conduction may be formed in a wired form, such as by a conductor element, or in a wireless form, such as Bluetooth, Wi-Fi, or RFID. In one embodiment, the conduction may also include the meaning of "communication."

[0061] The term "fluid" used in the following description refers to any form of material that can flow and change shape or volume, etc., due to an external force. In one embodiment, the fluid may be a liquid such as water or a gas such as air.

[0062] The terms “upper side,” “lower side,” “left side,” “right side,” “front side,” and “rear side” used in the following description shall be understood with reference to the coordinate system depicted throughout the attached drawings.

[0063] Referring to FIGS. 1 to 3, a tank heat dissipation assembly (10) according to an embodiment of the present invention is illustrated. The tank heat dissipation assembly (10) according to the present embodiment may be configured to include a tank member (100) that accommodates the configuration of a transformer and a configuration (i.e., a heat dissipation member (200) to be described later) that is coupled to the tank member (100) to cool heat.

[0064] At this time, the tank heat dissipation assembly (10) according to the present embodiment can stably maintain the bonding state of the heat dissipation member (200) and the tank member (100) by reducing the stress concentration caused by vibration generated in the tank member (100). Accordingly, the heat generated as the transformer operates can be effectively cooled, while the bonding strength between each component of the tank heat dissipation assembly (10) can be improved.

[0065] It is assumed that the tank heat dissipation assembly (10) according to the embodiment of the present invention described below is installed and used in a transformer. Alternatively, it will be understood that the tank heat dissipation assembly (10) may be installed and utilized in any device that requires cooling during operation.

[0066] In the illustrated embodiment, the tank heat dissipation assembly (10) includes a tank member (100), a heat dissipation member (200), and a reinforcing member (300). In addition, the tank heat dissipation assembly (10) further includes a fastening member (400) for joining the heat dissipation member (200) and the reinforcing member (300) (see FIG. 6).

[0067] The tank member (100) accommodates a configuration related to a transformer. The interior of the tank member (100) is electrically connected to the exterior, so that power can be supplied to the transformer, and the boosted or reduced power can be supplied to the exterior.

[0068] A fluid for insulation (hereinafter referred to as "insulating fluid") may be accommodated inside the tank member (100). The insulating fluid may surround a transformer accommodated inside the tank member (100). The insulating fluid may electrically insulate the transformer from the outside.

[0069] In addition, the insulating fluid can transfer heat generated in the transformer to the tank member (100). The transferred heat can be transferred to the heat dissipation member (200) and discharged to the outside. Accordingly, the tank member (100) and the transformer housed in the tank member (100) can be cooled.

[0070] The tank member (100) is coupled with a heat dissipation member (200). Heat transferred to the tank member (100) can be transferred to the heat dissipation member (200). In the illustrated embodiment, one longitudinal side of the tank member (100), i.e., the rear side, is coupled with the heat dissipation member (200).

[0071] At this time, the tank member (100) can be combined with a plurality of heat dissipation members (200). That is, as will be described later, two or more heat dissipation members (200) can be provided, and the tank member (100) can be combined with each of the plurality of heat dissipation members (200) to transfer heat.

[0072] Accordingly, it will be understood that as the number of heat dissipation members (200) combined with the tank member (100) increases, the cooling efficiency of the tank member (100) and the transformer accommodated therein can be improved.

[0073] The tank member (100) can be provided in any shape that can accommodate an insulating fluid and a transformer inside and can transfer heat by being combined with a heat dissipation member (200). In the illustrated embodiment, the tank member (100) is provided as a polygonal prism-shaped enclosure having a length in the front-back direction, a width in the left-right direction, and a height in the up-down direction.

[0074] The heat dissipation member (200) is coupled to the tank member (100) and receives heat from the tank member (100). The heat dissipation member (200) can release the transferred heat to the outside. Accordingly, the tank member (100), the transformer contained therein, and the heat dissipation member (200) can be cooled.

[0075] The heat dissipation member (200) can be coupled to the tank member (100) at any location where heat can be transferred from the tank member (100). In the illustrated embodiment, the heat dissipation member (200) is coupled to one side of the tank member (100) in the longitudinal direction, i.e., the rear side.

[0076] A plurality of heat dissipation members (200) may be provided. The plurality of heat dissipation members (200) may be spaced apart from each other and respectively coupled to the tank member (100) at different locations. In the illustrated embodiment, the heat dissipation member (200) includes a first heat dissipation member (200a) positioned on one side of the tank member (100) in the width direction, i.e., on the left side, and a second heat dissipation member (200b) positioned on the other side of the width direction, i.e., on the right side.

[0077] The first heat dissipation member (200a) and the second heat dissipation member (200b) are spaced apart from each other along the width direction of the tank member (100). Accordingly, the amount of heat emitted from each heat dissipation member (200a, 200b) that is transferred to the other heat dissipation member (200a, 200b) can be minimized.

[0078] Meanwhile, as the first heat dissipation member (200a) and the second heat dissipation member (200b) are each coupled to the tank member (100), vibrations generated in the tank member (100) may be transmitted to the first heat dissipation member (200a) and the second heat dissipation member (200b), respectively. Accordingly, there is a concern that the first heat dissipation member (200a) and the second heat dissipation member (200b), which are spaced apart from each other, may vibrate, thereby reducing the coupling strength with the tank member (100).

[0079] To this end, the heat dissipation member (200) is coupled to the reinforcing member (300). Accordingly, the first heat dissipation member (200a) and the second heat dissipation member (200b) are coupled to the tank member (100) and to each other at the same time, thereby minimizing the influence of transmitted vibrations. A detailed description thereof will be omitted.

[0080] Meanwhile, the first heat dissipation member (200a) and the second heat dissipation member (200b) differ in their connection positions with the tank member (100), but their other structures and functions are the same. Accordingly, in the following description, the common parts of the first heat dissipation member (200a) and the second heat dissipation member (200b) are collectively referred to as the heat dissipation member (200).

[0081] The heat dissipation member (200) is coupled to the fastening member (400). The heat dissipation member (200) can be coupled to the reinforcing member (300) by the fastening member (400).

[0082] The heat dissipation member (200) may be formed of a material with high thermal conductivity. This is to improve heat exchange efficiency with the tank member (100). The heat dissipation member (200) may be formed of a material with high rigidity. This is to minimize weakening of the bonding strength and damage caused by vibrations generated in the tank member (100).

[0083] In one embodiment, the heat dissipation member (200) may be formed of copper (Cu), aluminum (Al), or an alloy material including these.

[0084] The heat dissipation member (200) may be provided in any form that can effectively dissipate heat transferred from the tank member (100). As will be described below, in one embodiment, the heat dissipation member (200) may be provided in the form of a heat dissipation fin including a plurality of heat dissipation plates (210).

[0085] In the embodiments illustrated in FIGS. 4 to 7, the heat dissipation member (200) includes a heat dissipation plate (210), a support member (220), a bonding member (230), and a pad member (240).

[0086] The heat dissipation plate (210) substantially performs the role of dissipating heat transferred from the tank member (100) to the outside. The heat dissipation plate (210) may be combined with other components of the heat dissipation member (200) and indirectly combined with the tank member (100).

[0087] The heat dissipation plate (210) is positioned facing the tank member (100) with a portion of the support member (220) interposed therebetween. In the illustrated embodiment, the heat dissipation plate (210) is positioned on the rear side of the support member (220) and is positioned facing the tank member (100) positioned on the front side.

[0088] The heat dissipation plate (210) is coupled to a support member (220). The heat dissipation plate (210) is supported by the support member (220) and can be coupled to the tank member (100). Specifically, the heat dissipation plate (210) coupled to the support member (220) can be coupled to the tank member (100) by a coupling member (230) to transfer heat.

[0089] Specifically, one side in the height direction of the heat dissipation plate (210), i.e., the upper side, is supported by being coupled with the first support member (221). The other side in the height direction of the heat dissipation plate (210), i.e., the lower side, is supported by being coupled with the second support member (222). One side of each side of the heat dissipation plate (210) facing the tank member (100), i.e., the front side in the illustrated embodiment, is supported by being coupled with the third support member (223).

[0090] The heat dissipation plate (210) may have any shape that can effectively dissipate the transferred heat. In the illustrated embodiment, the heat dissipation plate (210) is provided in the shape of a polygonal plate having a length in the vertical direction longer than a width in the left-right direction and a thickness in the front-back direction.

[0091] A plurality of heat dissipation plates (210) may be provided. The plurality of heat dissipation plates (210) may be spaced apart from each other along the length direction of the tank member (100). The plurality of heat dissipation plates (210) may be supported on each side in the height direction by a support member (220), specifically, a first support member (221) and a second support member (222).

[0092] A plurality of heat dissipation plates (210) can each receive heat transmitted through the support member (220) and each release the received heat to the outside.

[0093] The support member (220) is coupled to the heat dissipation plate (210) to support it. In addition, the support member (220) is coupled to the tank member (100) through the coupling member (230) to receive heat. That is, the support member (220) is coupled to the heat dissipation plate (210) and the coupling member (230), respectively, to form a passage through which heat transferred from the tank member (100) moves.

[0094] In addition, the support member (220) is coupled with the pad member (240). As will be described later, a reinforcing member (300) may be coupled to the pad member (240). Therefore, it can be said that the support member (220) is coupled with the reinforcing member (300) via the pad member (240).

[0095] The support member (220) may be provided in any shape that can receive heat generated from the tank member (100) and transfer it to the heat dissipation plate (210). In the illustrated embodiment, the support member (220) is provided as a circular pipe.

[0096] In one embodiment, a hollow may be formed inside the support member (220). In the embodiment, the support member (220) may be connected to the tank member (100) through a connecting member (230). That is, in the embodiment, a hollow may also be formed inside the connecting member (230), and may be connected to the hollow formed inside the support member (220).

[0097] In the above embodiment, the insulating fluid contained inside the tank member (100) flows along the joint member (230) and the support member (220) and can exchange heat with them. That is, the heat of the insulating fluid can be transferred to the heat dissipation plate (210) through the support member (220) and released to the outside.

[0098] In the above embodiment, heat generated in the transformer is transferred to the heat dissipation member (200) through the tank member (100) itself, and can also be transferred to the heat dissipation member (200) through the insulating fluid that has exchanged heat with the transformer. Accordingly, the cooling efficiency of the transformer and the tank member (100) containing the transformer can be improved.

[0099] In the illustrated embodiment, the support member (220) includes a first support member (221), a second support member (222), and a third support member (223).

[0100] The first support member (221) supports the heat dissipation plate (210) on one side in the height direction, the upper side in the illustrated embodiment. The first support member (221) is coupled to the upper side of the heat dissipation plate (210).

[0101] The first support member (221) may extend along the direction in which the plurality of heat dissipation plates (210) are arranged in parallel with each other. The first support member (221) may be coupled to the upper sides of the plurality of heat dissipation plates (210) to transfer heat. In the illustrated embodiment, the first support member (221) extends in the front-back direction and is coupled to the upper sides of the plurality of heat dissipation plates (210) that are arranged spaced apart from each other in the front-back direction to support them.

[0102] The first support member (221) is coupled to the third support member (223). The first support member (221) can receive heat from the third support member (223).

[0103] The first support member (221) is placed facing the second support member (222) with the heat dissipation plate (210) interposed therebetween.

[0104] The second support member (222) supports the heat dissipation plate (210) from the other side in the height direction, the lower side in the illustrated embodiment. The second support member (222) is coupled to the lower side of the heat dissipation plate (210).

[0105] The second support member (222) may extend along the direction in which the plurality of heat dissipation plates (210) are arranged in parallel. The second support member (222) may be respectively coupled to the lower sides of the plurality of heat dissipation plates (210) to transfer heat. In the illustrated embodiment, the second support member (222) extends in the front-back direction and is respectively coupled to the lower sides of the plurality of heat dissipation plates (210) that are arranged spaced apart from each other in the front-back direction to support them.

[0106] Accordingly, it will be understood that the plurality of heat dissipation plates (210) are positioned between and supported by the first support member (221) and the second support member (222) along the height direction thereof. Consequently, the heat transferred to the third support member (223) is divided into the first support member (221) and the second support member (222) and transferred to the heat dissipation plate (210) respectively, so that the cooling efficiency can be improved.

[0107] In addition, the second support member (222) constitutes a portion where the heat dissipation member (200) is coupled to the tank member (100). One end of the second support member (222) in the extension direction, the front end in the illustrated embodiment, is coupled to the tank member (100) and can receive heat from the tank member (100). The heat transferred to the second support member (222) can be transferred to the heat dissipation plate (210) or the third support member (223).

[0108] In the above embodiment, the front end of the second support member (222) and the front end of the coupling member (230) can be positioned at the same position along the front-back direction. In other words, the second support member (222) and the coupling member (230) can be simultaneously coupled to the tank member (100).

[0109] The second support member (222) is coupled to the third support member (223). The second support member (222) can receive heat from the third support member (223).

[0110] The third support member (223) is coupled to the connecting member (230) to receive heat. In addition, the third support member (223) is coupled to the first support member (221) and the second support member (222) to connect them. The heat transferred to the third support member (223) can be transferred to the first support member (221) and the second support member (222), respectively.

[0111] The third support member (223) is coupled with the pad member (240). As will be described later, a reinforcing member (300) may be coupled to the pad member (240). At this time, the pad member (240) may be coupled to one side of the outer circumference of the third support member (223).

[0112] The third support member (223) extends in the height direction of the heat dissipation plate (210), in the vertical direction in the illustrated embodiment. One side of the extension direction of the third support member (223), in the illustrated embodiment, the upper side, is coupled with the first support member (221). The other side of the height direction of the third support member (223), in the illustrated embodiment, the lower side, is coupled with the second support member (222).

[0113] The third support member (223) is coupled to the connecting member (230). The third support member (223) can be coupled to the tank member (100) by the connecting member (230). In addition, the third support member (223) can be spaced apart from the tank member (100) and the heat dissipation plate (210) by the connecting member (230). The third support member (223) is positioned between the tank member (100) and the heat dissipation plate (210).

[0114] At this time, the third support member (223) can be coupled with the coupling member (230) at any position between a pair of points coupled with the first support member (221) and the second support member (222). In the illustrated embodiment, the third support member (223) is coupled with the coupling member (230) at a point tilted toward the upper side coupled with the first support member (221).

[0115] The connecting member (230) is another part where the heat dissipation member (200) is connected to the tank member (100). The connecting member (230) is connected to the tank member (100) and receives heat from the tank member (100).

[0116] The joining member (230) is joined to the supporting member (220). Specifically, the joining member (230) is joined to the third supporting member (223). Heat transferred to the joining member (230) can be transferred to the heat dissipation plate (210) via the third supporting member (223).

[0117] The coupling member (230) extends between the tank member (100) and the third support member (223). In the illustrated embodiment, the coupling member (230) extends in the front-back direction. One end of the coupling member (230) in the extending direction, the front end in the illustrated embodiment, is coupled to the tank member (100). The other end of the coupling member (230) in the extending direction, the rear end in the illustrated embodiment, is coupled to the third support member (223).

[0118] Accordingly, the support member (220) can be connected to the tank member (100) at multiple points. Accordingly, the stress applied to the support member (220) is distributed, thereby improving the vibration resistance of the transformer and the tank member (100) that accommodates it.

[0119] The pad member (240) is a portion where the heat dissipation member (200) is joined to the reinforcing member (300). The pad member (240) is joined to the outer periphery of the support member (220) and is joined to the reinforcing member (300). In one embodiment, the pad member (240) may be joined by welding to the outer periphery of the support member (220).

[0120] The pad member (240) can be positioned at any location where the reinforcing member (300) can be coupled. In the illustrated embodiment, the pad member (240) is coupled to one side of the outer circumference of the third support member (223) extending in the vertical direction.

[0121] Specifically, in an embodiment in which a plurality of heat dissipation members (200a, 200b) are provided, the pad member (240) may be positioned on the inner outer periphery of the third support member (223) provided to each heat dissipation member (200a, 200b).

[0122] That is, the pad member (240) of the first heat dissipation member (200a) can be positioned on the right outer periphery of the third support member (223), and the pad member (240) of the second heat dissipation member (200b) can be positioned on the left outer periphery of the third support member (223). The pad members (240) provided on each heat dissipation member (200a, 200b) are positioned to face each other.

[0123] The pad member (240) is coupled to the fastening member (400). The pad member (240) can be coupled to the reinforcing member (300) via the fastening member (400).

[0124] The pad member (240) may have any shape that can be coupled to the support member (220) and coupled to the reinforcing member (300) by the fastening member (400). In the illustrated embodiment, the pad member (240) is formed in a polygonal plate shape with a rectangular cross-section and a thickness in the front-back direction.

[0125] A pad hollow (240a) may be formed through the interior of the pad member (240). The pad hollow (240a) is formed through the thickness direction of the pad member (240), i.e., in the front-back direction in the illustrated embodiment. A fastening member (400) may be formed through the pad hollow (240a).

[0126] A plurality of pad members (240) may be provided. The plurality of pad members (240) may be spaced apart from each other and may be respectively coupled to the support member (220), the reinforcing member (300), and the fastening member (400) at different locations. In the illustrated embodiment, the pad members (240) are provided in pairs, including a first pad member (241) and a second pad member (242).

[0127] The first pad member (241) is positioned adjacent to one longitudinal side of the third support member (223), in the illustrated embodiment, the upper end. The first pad member (241) may be positioned adjacent to the first support member (221). The first pad member (241) may be coupled to the reinforcing arm (310, 320) by the first fastening member (410).

[0128] The second pad member (242) is positioned on the other side of the third support member (223) in the longitudinal direction, i.e., the lower side in the illustrated embodiment. The second pad member (242) may be positioned adjacent to the coupling member (230). The second pad member (242) may be coupled to the reinforcing arm (310, 320) by the second fastening member (420).

[0129] The number and arrangement structure of the pad member (240) can be changed in accordance with the number and structure of the reinforcing arms (310, 320) provided in the reinforcing member (300).

[0130] The reinforcing member (300) is respectively connected to a plurality of heat dissipation members (200a, 200b). The reinforcing member (300) supports the plurality of heat dissipation members (200a, 200b). Accordingly, when viewed from the perspective of the tank member (100), the plurality of heat dissipation members (200a, 200b) can be treated as a single heat dissipation member (200). At this time, the single heat dissipation member (200) can have a larger size and mass than the plurality of heat dissipation members (200a, 200b).

[0131] Accordingly, the frequency and energy due to vibration transmitted from the transformer and the tank member (100) accommodating the transformer are reduced, and as a result, the magnitude of stress applied to the support member (220) can be reduced.

[0132] The reinforcing member (300) is positioned between the tank member (100) and the heat dissipation plate (210). The reinforcing member (300) may be positioned spaced apart from the tank member (100) and the heat dissipation plate (210).

[0133] The reinforcing member (300) is coupled to the heat dissipation member (200). Specifically, the reinforcing member (300) is coupled to the pad member (240).

[0134] The reinforcing member (300) is coupled to the fastening member (400). The reinforcing member (300) can be coupled to the pad member (240) by the fastening member (400).

[0135] The reinforcing member (300) may be formed of a high-strength material. This is to ensure that the bonding state of the first heat dissipation member (200a) and the second heat dissipation member (200b), each of which is coupled to the reinforcing member (300), is stably maintained. In one embodiment, the reinforcing member (300) may be formed of iron (Fe) or an alloy material containing iron (Fe).

In the illustrated embodiment, the tank heat dissipation assembly (20) includes a tank member (100), a heat dissipation member (200), a reinforcing member (300), and a fastening member (400).

[0183] The tank heat dissipation assembly (20) according to the present embodiment has differences in the structure and number of heat dissipation members (200) and the number of reinforcing members (300) compared to the tank heat dissipation assembly (10) according to the above-described embodiment.

[0184] That is, the tank heat dissipation assembly (20) according to the present embodiment can further increase the heat dissipation and cooling effect by including a greater number of heat dissipation members (200) and reinforcing members (300).

[0185] Accordingly, the structure and function of the tank member (100), reinforcing member (300), and fastening member (400) will be replaced with the description of the tank heat dissipation assembly (10) according to the above-described embodiment.

[0186] In the present embodiment, the heat dissipation member (200) is configured to further include a third heat dissipation member (200c) in addition to the first heat dissipation member (200a) and the second heat dissipation member (200b).

The first to third heat dissipation members (200a, 200b, 200c) are each coupled to the tank member (100) to transfer heat.

[0187] At this time, the first heat dissipation member (200a) located on the far left is identical to the first heat dissipation member (200a) according to the above-described embodiment. In addition, the third heat dissipation member (200b) located on the far right is identical to the second heat dissipation member (200b) according to the above-described embodiment.

[0188] The second heat dissipation member (200b) located in the center has some differences in the number and position of pad members (240) combined with the support member (220).

[0189] The second heat dissipation member (200b) is configured to include a total of two pairs of pad members (240). One pair of pad members (240) is positioned on one side of the outer circumference of the third support member (223), on the left side in the illustrated embodiment. The other pair of pad members (240) is positioned on the other side of the outer circumference of the third support member (223), on the right side in the illustrated embodiment.

[0190] That is, each pair of pad members (240) provided on the second heat dissipation member (200b) is arranged to face the first heat dissipation member (200a) and the third heat dissipation member (200c), respectively.

[0193] Meanwhile, as the number of heat dissipation members (200) increases, the number of reinforcing members (300) may also increase correspondingly.

[0194] That is, in the illustrated embodiment, the reinforcing member (300) is provided as a pair, including a first reinforcing member (300a) and a second reinforcing member (300b). It will be understood that the number of reinforcing members (300) is one less than the number of heat dissipation members (200).

[0195] The first reinforcing member (300a) is positioned on the left side and is connected to the first heat dissipation member (200a) and the second heat dissipation member (200b), respectively. In addition, the second reinforcing member (300b) is positioned on the right side and is connected to the second heat dissipation member (200b) and the third heat dissipation member (200c), respectively.

[0196] Accordingly, even when three or more heat dissipation members (200) are provided, a plurality of heat dissipation members (200) can be respectively joined by reinforcing members (300), so that the bonding strength with the tank member (100) can be reinforced.

[0197] Although not shown, if the number of heat dissipation members (200) is further increased, the number of reinforcing members (300) may also be further increased and may be coupled to each other as described above. In this case, it will be understood that the other heat dissipation member (200) positioned between the pair of heat dissipation members (200) located at the outermost side is provided with the structure of the second heat dissipation member (200b) described above (i.e., including two pairs of pad members (240).

[0198] Accordingly, the tank heat dissipation assembly (10, 20) according to an embodiment of the present invention can vary its cooling capacity in accordance with the amount of heat generated in the transformer and the tank member (100) including the transformer.

[0199] Referring to FIGS. 12 and 13, experimental examples of stress distribution formed in a tank heat dissipation assembly (1000) according to a prior art and a tank heat dissipation assembly (10) according to an embodiment of the present invention are illustrated as examples.

[0200] Referring to Fig. 12, stress is concentrated on a joining member (1210) provided in a tank heat dissipation assembly (1000) according to the prior art. At this time, the maximum value of the stress concentrated on the joining member (1210) was measured to be approximately 300 MPa.

[0201] Referring to FIG. 13, stress is concentrated on a joining member (230) provided in a tank heat dissipation assembly (10) according to an embodiment of the present invention. At this time, the maximum value of the stress concentrated on the joining member (230) was measured to be approximately 225 MPa, which is a value that is approximately 25% reduced compared to the case of a tank heat dissipation assembly (1000) according to the prior art.

[0202] Accordingly, as the reinforcing member (300) is provided, the stress applied to the joining member (230), which is a configuration in which the heat dissipation member (200) is joined to the tank member (100), can be reduced. As a result, the joining force between the heat dissipation member (200) and the tank member (100) is improved, and the cooling efficiency of the transformer and the tank member (100) that accommodates it can also be improved.

[0203] Although not shown, it will be understood that a tank heat dissipation assembly (20) according to another embodiment of the present invention may also have a stress distribution of the form shown in FIG. 13.

[0204] Although the embodiments of the present invention have been described, the spirit of the present invention is not limited to the embodiments presented in this specification, and those skilled in the art who understand the spirit of the present invention will be able to easily propose other embodiments by adding, changing, deleting, or adding components within the scope of the same spirit, but this will also be considered to fall within the spirit of the present invention.
