DETAILED DESCRIPTION

[0024] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The utility model provides an embodiment: an outdoor transformer cabinet, comprising: the cabinet 1, the base 2, the rain cover 3 and the fan 94 used in the present application are all products that can be directly purchased on the market, and their principles and connection methods are all existing technologies well known to those skilled in the art, so they will not be repeated here.

[0026] The cabinet body 1 has a first heat dissipation hole 11 in the lower half of the cabinet body 1;

[0027] The partition 4 is connected to the inner wall of the cabinet 1. The upper half of the partition 4 is provided with a second heat dissipation hole 41. The first heat dissipation hole 11 and the second heat dissipation hole 41 are arranged in an upper and lower staggered manner to achieve air circulation while effectively preventing rainwater from entering, thereby greatly improving the safety of the electrical components inside the cabinet 1.

[0028] The heat dissipation component 9 is arranged between the cabinet 1 and the partition 4. The heat dissipation component 9 includes a guide groove 91. The outer wall of the guide groove 91 is fixedly connected with a positioning plate 92. The positioning plate 92 is fixedly connected to the inner wall of the cabinet 1. A positioning frame 93 is arranged below the positioning plate 92. The inner wall of the positioning frame 93 is fixedly connected with a fan 94 and a second filter 95. Through the arrangement of this structure, the air circulation in the heat dissipation channel between the cabinet 1 and the partition 4 can be accelerated, thereby improving the heat dissipation effect inside the cabinet 1.

[0029] Furthermore, a rain cover 3 is fixedly connected to the top of the cabinet 1, and the edge of the rain cover 3 is inclined to facilitate the diversion of rainwater. A base 2 is fixedly connected to the bottom of the cabinet 1, and an inspection door is provided on one side of the cabinet 1 to facilitate the inspection of internal electrical components.

[0030] Furthermore, rectangular grooves are provided on both sides of the bottom plate of the cabinet 1 , and the inner walls of the rectangular grooves are connected to positioning frames 93 . There are two groups of heat dissipation components 9 , and the two groups of heat dissipation components 9 are symmetrically distributed on both sides above the bottom plate of the cabinet 1 .

[0031] Furthermore, the inner wall of the cabinet 1 is fixedly connected with a support frame 5 and an air expansion plate 6, a circular through hole is opened in the center of the air expansion plate 6, and the inner wall of the circular through hole is connected with an air guide plate 7. Through the setting of the air guide plate 7, the air entering the interior of the cabinet 1 can be guided, so that the air is in full contact with the interior of the cabinet 1, thereby improving its heat dissipation effect.

[0032] Furthermore, the air diffuser 6 is of a conical structure, and two groups of air guide plates 7 are provided. The two groups of air guide plates 7 are symmetrically distributed, and the tops of the air guide plates 7 are inclined.

[0033] Furthermore, a positioning hole is opened at the center of the bottom plate of the cabinet 1, and the inner wall of the positioning hole is fixedly connected to the first filter 8, and the bottom of the bottom plate of the cabinet 1 is fixedly connected to the first steering plate 81 and the second steering plate 82. The first steering plate 81 and the second steering plate 82 have the same structure, and the first steering plate 81 and the second steering plate 82 are inclined and symmetrical at forty-five degrees about the center of the first filter 8. Through the arrangement of the first steering plate 81 and the second steering plate 82, a certain blocking and guiding effect can be played on the wind direction. The wind force blown to the inside of the first steering plate 81 or the second steering plate 82 is blown to the inside of the cabinet 1 after being blocked and diverted by the first steering plate 81 or the second steering plate 82, thereby further improving the air circulation effect. Moreover, the staggered distribution of the first steering plate 81 and the second steering plate 82 can ensure that the wind coming from both sides can be guided to the inside of the cabinet 1 through the first steering plate 81 or the second steering plate 82.

[0034] Furthermore, the guide groove 91 has a conical structure, and the minimum size of the guide groove 91 is smaller than the size of the rectangular groove of the cabinet 1. Three fans 94 are evenly distributed inside each positioning frame 93. By powering on the fans 94, air can be exhausted from the heat dissipation channel between the cabinet 1 and the partition 4, thereby improving the heat dissipation effect inside the cabinet 1.

[0035] Working principle: When the utility model is in use, but the temperature inside the cabinet 1 is too high, by starting the fan 94, it can complete the exhaust of the heat dissipation channel between the cabinet 1 and the partition 4, so that the high-temperature gas gathered at the top of the cabinet 1 is extracted through the guide of the second heat dissipation hole 41, and at the same time, wind can be blown in through the position of the first filter 8, thereby realizing air circulation inside the cabinet 1 and accelerating the heat dissipation process.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
