Marine jet flow induced draught cooling device

Abstract

The invention relates to a marine jet flow induced draught cooling device which comprises a box body, wherein a diagonal fan is arranged in the middle of the box body, a cooling device is arranged at the position of an air inlet of the diagonal fan, and jet flow nozzles are arranged on the front side, the left side, the right side and the lower side of the portion, in front of the air outlet portion of the diagonal fan, of the box body. Due to the fact that the jet flow nozzles are arranged on the left side, the right side and the lower side of the box body, the angle can be adjusted to enable air to be fed in all directions, and the air feeding range is wide.

Description

technical field [0001] The invention relates to the field of marine ventilation equipment, in particular to a marine jet flow induced air supply cooling device. Background technique [0002] With the global warming and the increase of equipment in the ship cabin, a large amount of heat emitted by the equipment is directly discharged into the cabin, causing the air temperature in the cabin to rise, which affects the accuracy and life of the equipment, so it is necessary to cool the cabin. Ship cabins originally used cooling equipment with large pressure head and high power, such as air conditioners to supply air for cooling through air ducts. Because there are many equipment in the cabin and they are not evenly distributed, there are structural girders and auxiliary beams on the top of the cabin, and the pipelines on the top There are so many cables, it is very difficult to arrange air ducts, and it is impossible to arrange air ducts in all positions, which is easy to ...

Ship cabins originally used cooling equipment with large pressure head and high power, such as air conditioners to supply air for cooling through air ducts. Because there are many equipment in the cabin and they are not evenly distributed, there are structural girders and auxiliary beams on the top of the cabin, and the pipelines on the top There are so many cables, it is very difficult to arrange the air ducts, and it is impossible to arrange the air ducts in all positions, which is easy to form dead angles, and the entire air supply cooling system takes up a lot of space, consumes a lot of power, and costs high

Patent 200920083680 discloses a ventilation and cooling device for marine propulsion motors. Its technical feature is to use two sets of parallel ventilation units to supply air to the propulsion motor through the diversion box. The air outlet of the ventilation units is provided with a cooling device. One of the limitations of this technical solution The disadvantages are: (1) The wind generated by the ventilation unit needs a diversion box for diversion, and the diversion box occupies a large space, wasting space and materials; (2) The fan unit can only generate directional and fixed-point cooling air, and the cooling range is small , waste of resources; (3) The air supply distance of the ventilation unit is small, and two or more groups of ventilation units need to be connected in parallel to meet the cooling demand
