Inside the housing 1, a mounting plate 2 is installed. At the top of the housing 1, a fan 3 is installed. At the input end of the fan 3, a telescopic tube 4 is fixed, and the bottom end of the telescopic tube 4 penetrates and extends into the interior of the housing 1. At the bottom end of the telescopic tube 4, a gas collecting pipe 5 is fixed. At the bottom of the housing 1, a motor 6 is installed. The output shaft of the motor 6 is fixed with a reciprocating screw 7. A slider 8 is slidably installed on the outer side of the reciprocating screw 7, and the slider 8 is fixedly connected to the gas collecting pipe 5. The output end of the mounting plate 2 is fixed with a fixed pipe 14. On one side of the housing 1, a heat exchange frame 11 is fixed, and the top of the heat exchange frame 11 is communicated with one end of the fixed pipe 14. Inside the heat exchange frame 11, a refrigeration sheet 12 is installed. On the side of the refrigeration sheet 12 away from the housing 1, a heat exchange plate 13 is installed. On the side of the slider 8 away from the gas collecting pipe 5, a scraper 9 is fixed, and one end of the scraper 9 penetrates and extends into the interior of the heat exchange frame 11. A through hole 10 is opened at the connection between the housing 1 and the scraper 9. At the top of the housing 1, a branch pipe 21 is provided. At the top of the branch pipe 21, an air outlet pipe 20 is fixed. At the middle position of the top of the air outlet pipe 20, a cooling pipe 19 is fixed, and the end of the cooling pipe 19 away from the air outlet pipe 20 is communicated with the top of the heat exchange frame 11.

[0026] Start the fan 3 and the motor 6, so that the fan 3 drives the telescopic tube 4 and the gas collecting pipe 5 to let the hot air and moisture inside the housing 1 enter the gas collecting pipe 5, and then be transported by the telescopic tube 4 into the heat exchange frame 11. The hot air contacts the refrigeration sheet 12 and exchanges heat with the refrigeration sheet 12, and condenses into water droplets. At the same time, the motor 6 drives the reciprocating screw 7 to rotate and drives the slider 8, the gas collecting pipe 5 and the scraper 9 to move up and down, so as to collect the hot air and moisture at different positions inside the housing 1, and the scraper 9 is used to clean the condensed water on the refrigeration sheet 12. Fix the mounting seat 18 on the ship. After the hot air inside the housing 1 exchanges heat through the refrigeration sheet 12, it enters the interior of the cooling pipe 19 and returns to the interior of the housing 1 through the air outlet pipe 20 and the branch pipe 21, achieving the purpose of continuously circulating and reducing the temperature inside the housing 1.

[0027] Embodiment Two

[0028] In this embodiment, as Figures 1 - 3 shown, a U-shaped plate 15 is fixed at the bottom of the housing 1. Fixing columns 16 are uniformly penetrated and installed at the bottom of the U-shaped plate 15, and the fixing columns 16 are all slidably connected to the U-shaped plate 15. Springs 17 are sleeved on the outer sides of the fixing columns 16, and a mounting seat 18 is fixed at the bottom of the fixing columns 16.

[0029] Fix the mounting seat 18 on the ship. When the hull sways up and down, it will drive the mounting seat 18 and the fixing columns 16 to move up and down. Under the elastic force of the springs 17, the influence of the amplitude of the hull's up and down sway on the housing 1 is weakened, and the stability of the installation of the circuit components inside the housing 1 is improved.

[0030] In this embodiment, a reinforcing pad is provided at the bottom of the mounting base 18, and the reinforcing pad is a rubber reinforcing pad.

[0031] The setting of the rubber reinforcing pad increases the friction with the ship and improves the firmness after installation.

[0032] In this embodiment, an isolation layer is provided on one side of the outer shell 1 close to the heat exchange frame 11, and the isolation layer is a temperature isolation layer.

[0033] The temperature isolation layer reduces the transfer of heat inside the outer shell 1 to the inside of the heat exchange frame 11 and improves the condensation efficiency.

[0034] In this embodiment, a protective pad is provided at the top of the fixed column 16, and the protective pad is an elastic protective pad.

[0035] The setting of the elastic protective pad improves the protection effect on the top of the fixed column 16 and reduces the impact force between the fixed column 16 and the top of the outer shell 1.
