a case 100;

the bottom plate 103 of the box body 100 is provided with a bottom heat-conducting plate 120, a bottom medium pipe 121 is arranged in the bottom heat-conducting plate 120, a side medium pipe 111 is arranged in the side plate 102 of the box body 100, the side medium pipe 111 is communicated with the bottom medium pipe 121, the box body 100 is internally provided with a circulating pump 400, a medium inlet and a medium outlet of the circulating pump 400 are connected with the side medium pipe 111 or the bottom medium pipe 121, and the circulating pump 400 works under the control of a temperature control switch.

Illustratively, a temperature-controlled switch is provided inside the tank 100, which is capable of constantly monitoring the temperature inside the tank 100 and turning on when the temperature reaches a set value, causing the circulation pump 400 to turn on the power, thereby causing the circulation pump 400 to operate to circulate the liquid medium in the bottom medium pipe 121 and the side medium pipe 111. Since the heat conductive plate 120 inside the case 100 is made of a material having a high thermal conductivity, it can absorb heat inside the case 100 and transfer it to the bottom medium pipe 121 and the liquid medium in the bottom medium pipe 121, and as the liquid medium flows, the heat can be transferred to the side plate 102 of the case 100 and finally emitted to the environment outside the case 100.

In the embodiment of the present application, the circulation pump 400, the bottom medium pipe 121 and the side medium pipe 111 are connected to form a circulation line, and the liquid medium flows out from the medium outlet after entering from the medium inlet of the circulation pump 400, and circulates inside the bottom medium pipe 121 and the side medium pipe 111 to continuously carry out heat inside the tank 100. Moreover, the side medium tubes 111 and the bottom medium tubes 121 need to have a greater density inside the side plates 102 and the bottom heat conductive plate 120, respectively, thereby improving heat conduction efficiency.

Further, the upper heat pipe 210 and the lower heat pipe 220 are both made of materials with high heat conductivity, and have hollow structures, and the liquid medium is provided inside the hollow structures, and can be vaporized at a relatively high temperature, for example, 50 ℃ or higher, the vaporized medium is collected at the top of the upper heat pipe 210, and the medium still in a liquid state is collected in the lower heat pipe 220, and because the upper heat pipe 210 and the heat dissipation fins 200 are in heat conduction connection, and the contact area between the heat dissipation fins 200 and the environment outside the box 100 is large, the heat of the vaporized medium in the upper heat pipe 210 can be quickly transferred to the heat dissipation fins 200 and dissipated to the environment outside the box 100. And when the vaporized medium is cooled, it is converted into liquid state and then flows back into the lower heat pipe 220, so as to form circulating passive heat dissipation.

In one possible embodiment, transformer heat sink 310 is disposed on the outer side of transformer body 300, and lower heat pipe 220 is disposed on transformer heat sink 310.

Illustratively, the transformer heat sink 310 is made of a material having a high thermal conductivity, a plurality of which may be vertically disposed on two opposite sides of the transformer body 300, respectively.

In one possible embodiment, the transformer heatsink 310 is provided with thermally conductive contact blocks 320 on sides thereof, and the lower heat pipe 220 passes through the thermally conductive contact blocks 320.

Illustratively, the heat conductive contact block 320 may be made of the same material as the transformer heat sink 310, and may be vertically disposed on the transformer heat sink 310 as a whole or may be a plurality of separate parts. If the heat conductive contact blocks 320 take a plurality of independent forms, the lower heat pipe 220 needs to pass through each of the heat conductive contact blocks 320 in sequence from top to bottom, and close contact between the lower heat pipe 220 and the heat conductive contact blocks 320 is maintained.

In one possible embodiment, the heat conductive contact blocks 320 are disposed on opposite sides of the transformer heat sink 310, respectively, and the heat conductive contact blocks 320 on each side are perforated with the lower heat pipes 220.

Illustratively, the number of upper heat pipes 210 is the same as the number of lower heat pipes 220, and the positions of the upper heat pipes 210 and the lower heat pipes 220 are in one-to-one correspondence, and when the lower heat pipes 220 are respectively disposed on two sides of each transformer heat sink 310, the same number of upper heat pipes 210 and lower heat pipes 220 need to be disposed to be correspondingly connected.

Illustratively, the communication location of the two lower heat pipes 220 is preferably provided at the bottom, i.e., the communicated lower heat pipes 220 form a U-shaped structure. When the two lower heat pipes 220 are connected, the lower heat pipes 220 and the upper heat pipes 210 connected with the lower heat pipes can form a larger U-shaped structure, so that the fluidity of the liquid medium in the heat pipes is increased.

In one possible embodiment, the case body 100 is provided on an outer side surface thereof with case body heat sink 110, and the side medium pipe 111 is provided inside the case body heat sink 110.

Illustratively, the case cooling fins 110 are also made of a material with high thermal conductivity, and a plurality of the case cooling fins may be vertically disposed on opposite outer sides of the case 100, respectively. By providing the case cooling fin 110, the contact area with the external environment can be increased, thereby improving the cooling efficiency.

In one possible embodiment, the side of the case 100 is provided with a door 101, and the door 101 is provided with a sealing lock.

For example, the sealing lock may be an automatic lock or a manual lock, and when the sealing lock is locked, the box door 101 is tightly attached to the box body 100, so as to isolate the external environment, so that the transformer body 300 inside the box body 100 can be in a good working environment and is not affected by the severe external environment.

Further, the cabinet 100 is provided with a sealing assembly at a position contacting the cabinet door 101. The sealing assembly can adopt sealing strips or sealing gaskets and the like, and can deform to a certain extent after being extruded by the box door 101, so that gaps between the box door 101 and the box body 100 are filled, and a good sealing effect is achieved.
