[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0036] See also Figure 1-5 The utility model discloses a transformer cooling device, which is used for cooling the transformer 01, and comprises:

[0037] A mounting substrate 1, wherein the mounting substrate 1 is disposed on the top of the heat dissipation fin 011;

[0038] A photovoltaic power generation component 2, wherein the photovoltaic power generation component 2 is arranged on the mounting substrate 1;

[0039] The heat dissipation component 3 is arranged on the mounting substrate 1 along the arrangement direction of the heat dissipation fins 011 . The heat dissipation component 3 is electrically connected to the photovoltaic power generation component 2 to accelerate the circulation of air between the heat dissipation fins 011 .

[0040] When in use, the present application can be quickly and conveniently set on the top of the heat dissipation fin 011 of the corresponding transformer 01. In hot weather, the electricity generated by the photovoltaic power generation component 2 can be used to drive the heat dissipation component 3 to accelerate the circulation of air between each heat dissipation fin 011 to achieve the purpose of cooling and heat dissipation.

[0041] It should be noted that if Figure 3 As shown, in order to improve the installation efficiency of the equipment and save manpower during installation, the installation substrate 1 is L-shaped;

[0042] The bottom of the mounting base plate 1 is provided with a clamping member 12 clamped between the two heat dissipation fins 011, wherein the clamping member 12 is composed of two groups of elastic members tilted outward, and the two groups of elastic members are used to resist the side walls of the heat dissipation fins 011 to achieve fixation;

[0043] The side of the mounting substrate 1 is provided with a magnetic attraction member 11 adsorbed on the transformer 01 .

[0044] With the above-mentioned structural setting, when installing the device, the mounting substrate 1 can be adsorbed onto the transformer 01 through the magnetic attraction member 11, and the mounting substrate 1 can be pressed down at the same time so that the clamping member 12 is clamped into the heat dissipation fin 011, thereby realizing quick installation of the device.

[0045] In a preferred embodiment, in order to further improve the heat dissipation and cooling effect, a spray component 4 is also provided;

[0046] The spray assembly 4 includes a power pump 41 electrically connected to the photovoltaic power generation assembly 2, a liquid supply pipe 43 and a conduit 44 respectively arranged at the input end and the output end of the power pump 41, and also includes a temperature sensing element 42. The temperature sensing element 42 is connected to the power pump 41 and is used to start the power pump 41 to spray coolant between the heat dissipation fins 011 when the temperature exceeds a threshold. It is easy to imagine that the device also includes a control unit, which is electrically connected to the temperature sensing element 42 and the power pump 41.

[0047] Through the above-mentioned structural setting, the temperature sensing element 42 obtains the temperature of the transformer 01. When the controller detects that the temperature of the transformer 01 exceeds a certain threshold and determines that emergency cooling is required, it can start the power pump 41, extract coolant through the liquid supply pipe 43, and spray it between each heat dissipation fin 011 through the conduit 44. The coolant takes away the heat on the heat dissipation fin 011, thereby realizing rapid cooling of the transformer 01.

[0048] In the present application, it should be supplemented that the photovoltaic power generation component 2 is arranged above the heat dissipation component 3 and is arranged parallel to the heat dissipation component 3;

[0049] A gap is left between the photovoltaic power generation component 2 and the heat dissipation component 3 for air circulation.

[0050] The photovoltaic power generation component 2 can be used to block direct sunlight from shining on the heat dissipation component 3, and can also prevent rain from corroding the heat dissipation component 3 in rainy weather.

[0051] It is easy to imagine that the mounting substrate 1 is provided with a plurality of placement holes 13;

[0052] The heat dissipation assembly 3 includes a connection bracket and a fan which are arranged in the placement hole 13 . The connection bracket is used to fix the fan at the axis of the placement hole 13 .

[0053] In order to further improve the heat dissipation effect and maximize the use of the coolant, the spray assembly 4 further includes an atomizing pipe 45, which is in multiple numbers and is connected to the conduit 44;

[0054] One end of the atomizing tube 45 extends into the placement hole 13;

[0055] A notch is provided on one side of the atomizing tube 45 close to the mounting substrate 1 to allow the coolant to flow down along the heat dissipating fins 011 .

[0056] During the process of the coolant output from the conduit 44, a part of the coolant can be discharged through the gap of the atomizing tube 45, so that it can be left along the heat dissipation fin 011 to reduce the surface temperature of the heat dissipation fin 011, while the other part of the coolant can flow into the placement hole 13 along the atomizing tube 45, and the coolant is hit by the fan blades arranged inside the atomizing tube 45 to be atomized into water droplets, and diffused around the transformer 01 with the circulation of air to cool down.

[0057] It is easy to imagine that in order to provide cooling liquid, the spray assembly 4 also includes a liquid supply part, and the liquid supply part is connected to the power pump 41 through a liquid supply pipe 43.

[0058] The above arrangement is for providing a liquid supply unit at the transformer 01 in hot weather to provide emergency cooling in emergency situations.

If the specific posture changes, the directional indication will also change accordingly.

[0060] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0061] In addition, "plurality" means two or more.
