Marine temperature self-adaptive air-cooled cabinet

Abstract

The invention discloses a marine temperature-adaptive air-cooled cabinet, the cabinet is a three-area cabinet composed of an air supply area, an equipment area and an air return area, the air supply area and the equipment area are further divided into a plurality of sub-areas in the vertical height, and the air supply sub-areas and the equipment sub-areas at the same height form a relatively independent heat dissipation unit; the public air return area collects hot air flowing out of the heat dissipation units. Through an air flow stabilizing and distributing mechanism composed of an air supply area cavity, an air supply pipe, a proportioning valve and a flow guide plate, air flow organization in the cabinet is clear, and heat exchange efficiency is improved. And the heat dissipation unit is combined with the multi-loop temperature control unit to form a temperature self-adaptive air cooling system with complete functions. According to the system, zoned control of temperature is realized, and the running condition of equipment in each heat dissipation unit is matched. And according to the temperature set value and the actual temperature feedback value, the branch cold air conveying amount is controlled as required, regional refined refrigeration management is achieved, and the energy consumption index of unit load is further reduced.

Description

technical field [0001] The application relates to a marine temperature-adaptive air-cooled cabinet, which belongs to the technical field of cooling and heat dissipation of marine data center cabinets. Background technique [0002] For a long time, information and communication technology (ICT) has not been applied on a large scale in the ship field due to the lack of demand for related businesses. Therefore, except for some special ships that carry out scientific research and exploration operations with simple small engine rooms, general transport ships Basically no separate IT room is set up. In this case, the cooling method of the cabinet is not designed according to the characteristics of the heat source, and the central air conditioner is usually used for unified cooling or the unit air conditioner is added on this basis. [0003] According to ship construction examples, regardless of whether there is a room or not, the heat dissipation of the cabinet basically complies...

Problems solved by technology

[0005] The technical problem to be solved in this application is the problem of uneven cooling and heat and poor heat dissipation caused by the poor air distribution of the traditional cooling method of the ship's IT cabinet, and the high space layout requirements of the land-use machine room cold pool technology when it is applied at the ship's end. Problems with poor energy performance for small-scale applications
