[0049] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating relative importance or indicating the number of technical features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The following is a more detailed description of the specific implementation of the present utility model in conjunction with specific embodiments:

[0050] like Figures 1 to 3 As shown, a temperature control cabinet 100 provided in an embodiment of the utility model is applied to a dissolved gas device. In this embodiment, the dissolved gas device is a dissolved gas device in a multi-component transformer oil. Of course, in actual application scenarios, the temperature control cabinet 100 of this embodiment can be applied to other equipment that requires auxiliary heat dissipation; the temperature control cabinet 100 provided in this embodiment can effectively assist the cabinet air conditioner to control the internal temperature of the cabinet, thereby realizing rapid cooling of the dissolved gas device under extreme ambient temperatures; the following is an explanation through specific implementation methods:

[0051] The temperature control cabinet 100 of this embodiment includes: an outer shell 1, an inner shell 2 arranged in the outer shell 1, and an adjustable heat dissipation component 3 arranged on the outer shell 1; the outer shell 1 is provided with a heat dissipation opening 11, and the adjustable heat dissipation component 3 is used to open and close the heat dissipation opening 11. When the adjustable heat dissipation component 3 opens the heat dissipation opening 11, the adjustable heat dissipation component 3 abuts against the inner shell 2; when the adjustable heat dissipation component 3 closes the heat dissipation opening 11, an insulating cavity 12 is formed between the outer shell 1 and the inner shell 2.

[0052] Here, it can be understood that the outer shell 1 refers to the outer shell of the temperature control cabinet 100, which plays a protective and heat dissipation role. The outer shell 1 is generally made of a heat dissipation material, which includes but is not limited to aluminum; the outer shell 1 is provided with a heat dissipation opening 11, and the heat dissipation opening 11 refers to an opening for heat dissipation opened on the outer shell 1. The heat of the temperature control cabinet 100 can be exchanged with the air through the heat dissipation opening 11. The location of the heat dissipation opening 11 is not limited. In this embodiment, the heat dissipation opening 11 is arranged to avoid the cabinet door, and the heat dissipation opening 11 is arranged on the side or back of the outer shell 1;

[0053] The inner shell 2 refers to the shell located inside the temperature control cabinet 100, and similarly, it plays a protective and heat dissipation role. The inner shell 2 is generally made of a heat dissipation material, including but not limited to aluminum. The inner shell 2 is arranged inside the outer shell 1, and a preset gap is spaced between the inner shell 2 and the outer shell 1 to form a heat insulation cavity 12.

[0054] The adjustable heat dissipation component 3 refers to a switch component used to adjust the temperature control cabinet 100 to switch different heat dissipation states; the adjustable heat dissipation component 3 is arranged on the outer shell 1; the adjustable heat dissipation component 3 is used to open and close the heat dissipation opening 11; when the adjustable heat dissipation component 3 opens the heat dissipation opening 11, the adjustable heat dissipation component 3 and the inner shell 2 physically contact to achieve heat conduction, so that the heat inside the temperature control cabinet 100 can be conducted from the inner shell 2 to the adjustable heat dissipation component 3 and the outer shell 1, and then the adjustable heat dissipation component 3 and the outer shell 1 are heat exchanged with the air, thereby improving the heat dissipation efficiency and achieving the cooling effect on the temperature control cabinet 100; when the adjustable heat dissipation component 3 closes the heat dissipation opening 11, the adjustable heat dissipation component 3 is no longer physically contacted with the inner shell 2, and a hollow insulation cavity 12 is formed between the outer shell 1 and the inner shell 2, so that the heat inside the temperature control cabinet 100 is isolated from being transferred to the outside, the heat dissipation efficiency is reduced, and the insulation effect of the temperature control cabinet 100 is achieved.

[0055] Optionally, a vacuum operation may be performed in the insulation cavity 12 to further improve the thermal insulation effect.

[0056] The working principle of the temperature control cabinet 100 provided in this embodiment is as follows:

[0057] In summer, the internal height of the temperature-controlled cabinet 100 is higher than the external ambient temperature, driving the adjustable heat dissipation component 3 to open the heat dissipation opening 11, and the adjustable heat dissipation component 3 abuts against the inner shell 2, so that the internal heat of the temperature-controlled cabinet 100 can be exchanged with the air at the heat dissipation opening 11 through the adjustable heat dissipation component 3, thereby achieving the cooling of the temperature-controlled cabinet 100 itself. At the same time, the cooling effect of the auxiliary cabinet air conditioner improves the heat dissipation efficiency of the dissolved gas device.

[0058] In winter, the internal height of the temperature control cabinet 100 is lower than the external ambient temperature, driving the adjustable heat dissipation component 3 to close the heat dissipation opening 11, and the adjustable heat dissipation component 3 is no longer in contact with the inner shell 2. At the same time, an insulating cavity 12 is formed between the inner shell 2, the outer shell 1 and the adjustable heat dissipation component 3. In this way, the insulating cavity 12 isolates the internal heat of the temperature control cabinet 100 from the heat exchange with the external air, thereby realizing the insulation of the temperature control cabinet 100 itself. At the same time, the heating effect of the auxiliary cabinet air conditioner reduces the heat dissipation efficiency of the dissolved gas device.

[0059] By adopting the above technical solution, the adjustable heat dissipation component 3 can adjust the working state according to the ambient temperature, open and close the heat dissipation opening 11, and then switch the different states of the temperature control cabinet 100, thereby assisting the cabinet air conditioner to quickly adjust the internal temperature of the cabinet to the ideal temperature and ensure the normal operation of the dissolved gas device.

[0060] In one embodiment, the adjustable heat dissipation assembly 3 includes a plurality of heat dissipation fins 31, which are arranged in sequence on the heat dissipation opening 11. The heat dissipation fins 31 are used to open and close the heat dissipation opening 11. When the heat dissipation fins 31 open the heat dissipation opening 11, the heat dissipation fins 31 abut against the inner shell 2; when the heat dissipation fins 31 close the heat dissipation opening 11, the plurality of heat dissipation fins 31 are connected end to end in sequence to close the heat dissipation opening 11.

[0061] Here, it can be understood that the heat sink 31 refers to a component used for heat dissipation; the heat sink 31 is generally made of heat dissipation material, such as aluminum alloy; multiple heat sinks 31 can be arranged on the heat dissipation opening 11 in sequence, that is, multiple heat sinks 31 can cover the entire heat dissipation opening 11; when the heat sink 31 opens the heat dissipation opening 11, the multiple heat sinks 31 are respectively abutted against the inner shell 2, so that the heat of the inner shell 2 can be dissipated through the multiple heat sinks 31; when the heat sink 31 closes the heat dissipation opening 11, the multiple heat sinks 31 are connected end to end in sequence to close the heat dissipation opening 11, to ensure that a closed insulation cavity 12 is formed between the inner shell 2 and the outer shell 1.

[0062] By adopting the above technical solution, the adjustable heat dissipation component 3 can open and close the heat dissipation opening 11.

[0063] like Figure 4 As shown, in one embodiment, the heat sink 31 includes a rotating shaft 311 and a heat sink body 312 , the rotating shaft 311 is connected to the outer shell 1 , the heat sink body 312 is connected to the rotating shaft 311 and can rotate around the rotating shaft 311 , so that the heat sink body 312 can open and close the heat dissipation opening 11 .

[0064] Here, it can be understood that the rotating shaft 311 refers to the shaft body when the heat sink body 312 rotates, the rotating shaft 311 is connected to the outer shell 1, the rotating shaft 311 can be arranged at both ends of the heat sink body 312 or penetrate the heat sink body 312; the heat sink body 312 refers to the main component used for heat dissipation, and the heat sink body 312 is rotatably connected to the outer shell 1 through the rotating shaft 311.

[0065] By adopting the above technical solution, the rotatable connection between the heat sink 31 and the outer shell 1 is achieved, so that the heat sink 31 is easy to operate to open and close the heat dissipation opening 11.

[0066] like Figure 5 and Figure 6 As shown, in one embodiment, the heat sink body 312 includes a first heat sink portion 3121, a second heat sink portion 3122 connected to the first heat sink portion 3121, and an elastic member 3123 connecting the first heat sink portion 3121 and the second heat sink portion 3122, and the first heat sink portion 3121 is connected to the rotating shaft 311; when the heat sink body 312 opens the heat dissipation opening 11, the second heat sink portion 3122 is used to elastically abut against the inner shell 2; when the heat sink body 312 closes the heat dissipation opening 11, the second heat sink portion 3122 is used to elastically abut against the adjacent first heat sink portion 3121.

[0067] Here, it can be understood that the heat sink body 312 is elastic, so that the heat sink body 312 can be elastically abutted against the inner shell 2. The heat sink body 312 is closely connected with the inner shell 2 under the action of elastic force, which is beneficial to the heat transfer of the inner shell 2 to the heat sink body 312, thereby ensuring the heat dissipation efficiency. Specifically, the heat sink body 312 includes a first heat dissipation portion 3121, a second heat dissipation portion 3122 and an elastic member 3123. The first heat dissipation portion 3121 is connected to the rotating shaft 311, and the second heat dissipation portion 3122 is connected to the rotating shaft 311. It is connected to the first heat dissipation part 3121, and the elastic member 3123 connects the second heat dissipation part 3122 and the first heat dissipation part 3121; when the heat dissipation opening 11 is opened by the heat dissipation body 3122, the second heat dissipation part 3122 elastically abuts against the inner shell 2 under the elastic force of the elastic member 3123; when the heat dissipation opening 11 is closed by the heat dissipation body 3122, the second heat dissipation part 3122 elastically abuts against the adjacent first heat dissipation part 3121 under the elastic force of the elastic member 3123, thereby ensuring the sealing of the closed insulation cavity 12.

[0068] By adopting the above technical solution, the degree of coordination between the heat sink body 312 and the inner shell 2 as well as the adjacent heat sink body 312 is improved, thereby improving the heat dissipation efficiency and the heat insulation efficiency.

[0069] In one embodiment, the end of the first heat dissipation part 3121 connected to the second heat dissipation part 3122 is provided with a plug-in part 3124, and the second heat dissipation part 3122 is provided with a plug-in cavity 3125 that cooperates with the plug-in part 3124, so that the second heat dissipation part 3122 can be extended and retracted relative to the first heat dissipation part 3121.

[0070] Here, it can be understood that the first heat dissipation portion 3121 and the second heat dissipation portion 3122 can be telescopically matched, so that the second heat dissipation portion 3122 can elastically abut against the inner shell 2 or the adjacent first heat dissipation portion 3121; specifically, the first heat dissipation portion 3121 is provided with a plug-in portion 3124, and the second heat dissipation portion 3122 is provided with a plug-in cavity 3125, and the plug-in portion 3124 is inserted in the plug-in cavity 3125 and is gap-matched with the plug-in cavity 3125, so that the plug-in portion 3124 can be telescoped relative to the plug-in cavity 3125, thereby realizing that the first heat dissipation portion 3121 and the second heat dissipation portion 3122 can be relatively telescopic.

[0071] By adopting the above technical solution, the first heat dissipation part 3121 and the second heat dissipation part 3122 can be telescopically matched.

[0072] In one embodiment, the plug-in cavity 3125 is provided with an anti-foolproof latch for limiting the plug-in portion 3124 .

[0073] Here, it can be understood that the anti-foolproof bayonet is used to prevent the plug-in part 3124 from being separated from the plug-in cavity 3125; specifically, the radial dimension of the anti-foolproof bayonet is smaller than the radial dimension of the plug-in cavity 3125, and the radial dimension of the plug-in part 3124 matches the plug-in cavity 3125, so that the plug-in part 3124 and the plug-in cavity 3125 are clearance-matched, and a limiting protrusion is provided at the front end of the plug-in part 3124, and the radial dimension of the limiting protrusion is larger than the radial dimension of the anti-foolproof bayonet and smaller than the radial dimension of the plug-in cavity 3125, so that the anti-foolproof bayonet can limit the plug-in part 3124 in the plug-in cavity 3125 to prevent the plug-in part 3124 from being separated from the plug-in cavity 3125.

[0074] By adopting the above technical solution, the possibility of the plug-in portion 3124 accidentally disengaging from the plug-in cavity 3125 is reduced, and the reliability of the heat sink 31 when switching between different states is improved.

[0075] In one embodiment, a first recess 21 corresponding to the second heat dissipation portion 3122 is provided on the surface of the inner shell 2 facing the heat dissipation opening 11. When the heat dissipation opening 11 is opened by the heat dissipation fin body 312, the end of the second heat dissipation portion 3122 facing away from the first heat dissipation portion 3121 is used to be inserted into the first recess 21.

[0076] Here, it can be understood that the first recess 21 is used to cooperate with the end of the second heat dissipation part 3122, that is, when the second heat dissipation part 3122 abuts against the inner shell 2, the end of the second heat dissipation part 3122 facing away from the first heat dissipation part 3121 just fits into the first recess 21, thereby achieving the fixation of the heat sink body 312.

[0077] By adopting the above technical solution, the heat sink body 312 is fixed, and the possibility of accidental separation of the heat sink body 312 and the inner shell 2 is reduced.

[0078] In one embodiment, the end of the second heat dissipation portion 3122 facing away from the first heat dissipation portion 3121 is provided with a first protrusion 31221 that cooperates with the first recess 21 .

[0079] Here, it can be understood that the shape and size of the first recess 21 match the shape and size of the first protrusion 31221, so that the first protrusion 31221 can just fit into the first recess 21. At the same time, the surface contact area between the first protrusion 31221 and the surface of the first recess 21 is increased, thereby improving the heat conduction speed between the heat sink body 312 and the inner shell 2.

[0080] Specifically, the first notch 21 is an arc-shaped notch, and the first protrusion 31221 is an arc-shaped protrusion. The notch and protrusion of the above shapes are easy to match.

[0081] By adopting the above technical solution, the contact area between the heat sink body 312 and the inner shell 2 is increased, and the heat conduction speed between the two is improved.

[0082] In one embodiment, the end of the first heat dissipation portion 3121 away from the second heat dissipation portion 3122 is provided with a second notch 31211 so that when the heat dissipation opening 11 is closed by the heat sink body 312 , the end of the adjacent second heat dissipation portion 3122 can be inserted into the second notch 31211 .

[0083] Here, it can be understood that the shape and size of the second recess 31211 match the shape and size of the first protrusion 31221, so that the first protrusion 31221 can just fit into the second recess 31211, ensuring that when the heat sink 31 closes the heat dissipation opening 11, a closed insulation cavity 12 is formed between the inner shell 2 and the outer shell 1, thereby improving the insulation effect of the insulation cavity 12.

[0084] Specifically, the second recess 31211 is an arc-shaped recess, and the first protrusion 31221 is an arc-shaped protrusion. The recesses and protrusions of the above shapes are easy to match.
