[0002] Ships are a general term for all kinds of vessels. They are means of transportation that can navigate or anchor in waterways for transport or operations. Ships have different technical performance, equipment, and structural types according to different usage requirements. Ships are man-made means of transportation that mainly operate in geographical waters. Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). They are the final-level equipment in the power distribution system. Distribution cabinets are a general term for the motor control center. On ships, distribution cabinets are indispensable equipment; they are the power hub of the ship. Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final-level equipment in the power distribution system.

[0003] Publication number CN219937734U mentions a high-efficiency heat dissipation distribution cabinet. By setting up a heat dissipation fan that is easy to install and disassemble, when the heat dissipation fan is damaged due to prolonged operation, it can be disassembled and replaced in time, ensuring that the heat dissipation fan can play its heat dissipation role. However, in use, relying solely on the heat dissipation fan for cooling will result in poor cooling effect, causing the distribution cabinet temperature to rise. Water cooling has the risk of leakage, which may damage the distribution cabinet. There is an urgent need for a high-efficiency heat dissipation type of marine distribution cabinet to solve the above problems. Utility Model Content

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-6 This utility model provides a technical solution: a high-efficiency heat dissipation type marine power distribution cabinet, including a cabinet body 1, a filter screen 2, an exhaust fan 3, and a high-speed cooling mechanism 4. A cabinet door handle 11 is installed on the front end of the cabinet body 1, and the cabinet body 1 and the cabinet door handle 11 are connected by a connecting hinge 12. A filter screen 2 is installed at the lower end of the right side of the cabinet body 1, and an exhaust fan 3 is installed inside the filter screen 2. A high-speed cooling mechanism 4 is installed on the upper surface of the cabinet body 1. The high-speed cooling mechanism 4 includes an outer air supply pipe 41, a vortex pipe 42, a U-shaped air supply pipe 43, a filter inlet pipe 44, a filter air channel, a liquid storage tank 46, a filter element 47, a filter exhaust pipe 48, and an air pump 49. The right end of the cabinet body 1... A U-shaped air supply pipe 43 is installed on the surface of the distribution cabinet 1. A vortex tube 42 is installed at the upper end of the cabinet body 1. An outer air supply pipe 41 is installed on the circumferential surface of the vortex tube 42. A filter exhaust pipe 48 is installed at the rear end of the outer air supply pipe 41. A filter channel 45 is installed at the rear end of the filter exhaust pipe 48. A filter inlet pipe 44 is installed at the rear end of the filter channel 45. A liquid storage tank 46 is installed at the lower end of the filter channel 45. A filter element 47 is installed inside the liquid storage tank 46. An air pump 49 is installed at the rear end of the filter inlet pipe 44. This design solves the problem that the original device relies solely on a cooling fan for cooling, which results in poor cooling effect and causes the temperature of the distribution cabinet to rise. Water cooling has the risk of leakage, which may damage the distribution cabinet.

[0022] As the first embodiment of this utility model: the exhaust fan 3 penetrates the surface of the distribution cabinet 1, and the surface size of the exhaust fan 3 is the same as the surface size of the filter screen 2. The U-shaped air supply pipe 43 is connected to the upper end of the left side of the distribution cabinet 1. An exhaust port 431 is installed at one end of the U-shaped air supply pipe 43 inside the distribution cabinet 1. The other end of the U-shaped air supply pipe 43 is connected to one end of the vortex pipe 42. A diffuser baffle 422 is provided at the other end of the vortex pipe 42. The surface size of the diffuser baffle 422 is smaller than that of the vortex pipe. The internal cross-sectional dimensions of the vortex tube 42 are as follows: the circumferential surface of the diffuser baffle 422 is inclined, and the surface of the diffuser baffle 422 on the inner side of the vortex tube 42 is smaller than that on the outer side of the vortex tube 42. By adding the diffuser baffle 422, the inner airflow of the cylindrical airflow can be blocked, and together with the vortex holes 421, the hot and cold airflows are separated. Nine vortex holes 421 are opened on the circumferential surface of the vortex tube 42, and each vortex hole 421 is inclined to the surface of the vortex tube 42. The angles are the same, and the tilt angle is towards the right end of the vortex tube 42. The outer air supply pipe 41 wraps around the surface of the vortex tube 42. By adding vortex holes 421, the straight airflow can be changed into a spiral airflow. The filter exhaust pipe 48 is connected to the outer air supply pipe 41, the filter intake pipe 44 is connected to the filter channel 45, and the filter channel 45 is connected to the filter exhaust pipe 48. A baffle is installed inside the filter channel 45, which isolates the internal connection of the filter channel 45. The lower surface of the filter channel 45 Two vent holes 451 are provided, which are connected to the filter exhaust pipe 48 and the filter inlet pipe 44 respectively. A filter element 47 is installed on the lower surface of the filter channel 45. The vent hole 451 connected to the filter inlet pipe 44 is located inside the filter element 47, and the vent hole 451 connected to the filter exhaust pipe 48 is located outside the filter element 47 and inside the liquid storage tank 46. An air plug 461 is installed at the lower end of the liquid storage tank 46. The air pump 49 is fixedly connected to the power distribution cabinet 1 through the air pump bracket 491.

[0023] As a second embodiment of this utility model: When the distribution cabinet needs heat dissipation, firstly, the air pump 49 and the cooling fan are turned on. The air pump 49 generates gas that enters the filter inlet pipe 44. The gas passes through the vent 451 and enters the filter element 47. The filter element 47 filters out residual impurities and moisture in the gas. Then, the gas is discharged from the filter element 47 and passes through the vent 451 connected to the filter exhaust pipe 48 to enter the filter exhaust pipe 48. Then, it enters the outer air supply pipe 41. The gas passes through the vortex hole 421 in the outer air supply pipe 41 and enters the vortex tube 42. When the gas enters the vortex tube 42, the vortex hole 421 turns the gas into a spiral shape. The spiral gas moves towards the right end of the vortex tube 42 and adheres to the inner wall of the vortex tube 42. When it reaches the diffuser baffle 422, the hot air is discharged from the outside of the diffuser baffle 422, while the cold air hits the diffuser baffle 422 and returns from the center of the vortex tube 42 until it reaches the U-shaped gas supply pipe 43. It then passes through the U-shaped gas supply pipe 43 and the exhaust port 431 and enters the power distribution cabinet 1. The gas temperature entering the power distribution cabinet 1 is low. It enters the power distribution cabinet 1 and cools the wires and switches and other components. The cold air undergoes a hot-cold conversion from top to bottom. The falling cold air will carry away the heat through the exhaust fan 3.
