[0002] The switch cabinet is an electrical equipment. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the branch control switch. Each branch is set according to its needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. The main function of the switch cabinet is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0020] Example:

[0021] See also Figure 1-Figure 6 The utility model provides a technical solution: an isolated heat dissipation switch cabinet for a wind turbine, comprising a housing 1; a rotating door 2, the outer side of the rotating door 2 is rotatably connected to the outer side of the housing 1; a rain shield 3, the bottom of the rain shield 3 is fixedly connected to the top of the housing 1; an air inlet device 4, the air inlet device 4 is used to let the air outside the switch cabinet in; a placement device 5, the bottom of the placement device 5 is fixedly connected to the bottom of the inner cavity of the housing 1, and the placement device 5 is used to place the electronic module unit required by the switch cabinet;

[0022] The placement device 5 includes a box body 51, the bottom of the box body 51 is fixedly connected to the bottom of the inner cavity of the shell 1, a ventilation slot 52 is opened in the wall of the box body 51, and a ventilation device 53 is fixedly connected to the inner side of the box body 51; a cooling device 6, the outer side of the cooling device 6 is fixedly connected to the top of the shell 1, and the cooling device 6 is used to cool the box body 51; the cooling device 6 is located below the rain shield 3, the outer side of the air inlet device 4 is fixedly connected to the two sides of the shell 1, and the air inlet device 4 is directly opposite to the ventilation slot 52;

[0023] The electronic module unit is fixedly installed inside the box body 51. When in use, the rotating door 2 is closed so that the inside of the box body 51 is in a sealed state. At this time, the box body 51 is isolated from the external environment, and the external air cannot enter the box body 51. After the switch cabinet has been used for a period of time, the equipment running in the switch cabinet generates heat, and the temperature inside the box body 51 rises. At this time, the external air enters the inside of the shell 1 through the air inlet device 4 on one side, and the air flows along the shell 1 to the inside of the ventilation slot 52, and then flows along the ventilation slot 52 to the air inlet device 4 on the other side. The air flows from the air inlet device 4 on the other side to the outside, and the airflow passes through the surface of the box body 51, taking away the heat of the box body 51. When the temperature inside the box body 51 is high, natural convection cannot be used to effectively dissipate heat. At this time, the box body 51 is cooled by the cooling device 6;

[0024] When in use, the switch cabinet is cooled by setting up a cooling device 6 and an air inlet device 4, and the heat generated during the working process is discharged in time, with high heat dissipation efficiency. During the ventilation process, the interior of the box body 51 is in a sealed state, and it is difficult for external dust to enter the interior of the box body 51, thereby avoiding dust accumulation inside the box body 51 and affecting the operation of the switch cabinet.

[0025] The ventilation device 53 includes a fixed column 531, the outer side of the fixed column 531 is fixedly connected to the inner side of the box body 51, the two ends of the fixed column 531 are fixedly connected with ventilation plates 532, and the inner side of the fixed column 531 is fixedly installed with a fan 533. When in use, the fan 533 in the ventilation device 53 drives the air flow, and the air above the box body 51 enters the inside of the fixed column 531 on one side. The air flow passes through the ventilation plates 532 at both ends of the fixed column 531 and flows downward to the bottom of the box body 51, and then flows to the inside of the fixed column 531 on the other side driven by the fan 533. The air flows upward along the fixed column 531 to the top of the box body 51, and the air flow inside the box body 51 is driven by the ventilation device 53 to circulate. The flow of air accelerates the loss of heat from the equipment, and in the process of air flow, the position of the air inside the box body 51 is changed, the heat dissipation dead angle is reduced, and the device dissipates heat evenly.

[0026] The cooling device 6 includes a heat sink 63, the outer side of the heat sink 63 is fixedly connected to the outer side of the box body 51, the outer side of the heat sink 63 is fixedly connected to a water pipe 62, the top of the shell 1 is fixedly connected to a water tank 61, the outer side of the water tank 61 is fixedly connected to both ends of the water pipe 62; the outer side of the water pipe 62 is fixedly connected to the outer side of the shell 1, both ends of the water pipe 62 penetrate the shell 1 and extend to the top of the shell 1, the water pipe 62 at the lowest point penetrates the box body 51 and is fixedly connected to the bottom of the inner cavity of the box body 51, and the temperature inside the box body 51 is When the temperature is high, the water pump in the water tank 61 starts, and the water pump drives the water in the water tank 61 to flow into the water pipe 62. The water flows downward along the water pipe 62 to the outside of the box body 51, and then flows to the bottom of the box body 51 along the water pipe 62. Finally, the water flows back to the inside of the water tank 61 along the water pipe 62. The heat sink 63 accelerates the heat dissipation speed of the box body 51. By setting the cooling device 6, the box body 51 is cooled, the cooling speed of the box body 51 is accelerated, and the heat generated during the working process is discharged in time, thereby ensuring the effective heat dissipation of the box body 51.

[0027] The air inlet device 4 includes a fixed frame 41, the outer side of the fixed frame 41 is fixedly connected to the outer side of the shell 1, the inner side of the fixed frame 41 is fixedly connected to a sieve plate 42, and an air inlet hole 43 is opened in the wall of the shell 1. When in use, the air flows along the fixed frame 41 on one side to the inside of the shell 1, and the air is filtered by the sieve plate 42, and then enters the inside of the shell 1 through the air inlet hole 43. The air flows along the shell 1 to the inside of the ventilation slot 52, and then flows along the ventilation slot 52 to the air inlet hole 43 on the other side. The air flows to the outside through the air inlet hole 43. By setting the air inlet device 4, natural convection is used to dissipate heat, save energy, and prevent dust in the air from entering the inside of the box body 51, thereby ensuring the normal operation of the switch cabinet.

[0028] Working principle:

[0029] When in use, the revolving door 2 is closed, the rain shield 3 can block the rain, and the equipment in the placement device 5 generates heat during operation, causing the temperature inside the box 51 to rise. At this time, the outside air flows into the inside of the shell 1 along the fixed frame 41 on one side, and the air flows along the fixed frame 41 to the sieve plate 42. After being filtered by the sieve plate 42, the air passes through the air inlet 43 and enters the inside of the shell 1. The air flows along the shell 1 to the inside of the ventilation slot 52, and then flows along the ventilation slot 52 to the air inlet 43 on the other side. The air flows to the outside through the air inlet 43. In this process, the airflow passes through the surface of the box 51 and takes away the heat of the box 51.

[0030] When the temperature inside the box 51 is high, the natural convection generated by the air inlet device 4 alone cannot effectively dissipate heat. At this time, the cooling device 6 is started, and the water pump in the water tank 61 drives the cold water to flow into the water pipe 62. The water flows downward along the water pipe 62 to the outside of the box 51, and then flows along the water pipe 62 to the bottom of the box 51. Finally, the water flows back to the inside of the water tank 61 along the water pipe 62. The heat sink 63 accelerates the heat dissipation speed of the box 51, and the water cools the box 51.

[0031] When the cooling device 6 is started, the fan 533 in the ventilation device 53 drives the air flow, and the air flow above the box 51 enters the inside of the fixed column 531 on one side. The air flow passes through the ventilation plates 532 at both ends of the fixed column 531 and flows downward to the bottom of the box 51, and then flows to the inside of the fixed column 531 on the other side driven by the fan 533. The air flows upward along the fixed column 531 to the top of the box 51. The air flow inside the box 51 circulates to accelerate the loss of heat from the equipment, and in the process of air flow, changes the position of the air inside the box 51, reduces the heat dissipation dead angle, and makes the device dissipate heat evenly.

[0032] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
