On the other hand, most of the ship's electrical equipment adopts fan cooling, which is the main source of air noise for the equipment. The peculiar smell inside the equipment will also be emitted into the cabin through the cooling channel, which will adversely affect the quality of the cabin's atmospheric environment, thereby affecting the design of the air purification system. Energy consumption, purification capacity, air volume and other parameters

The invention discloses an electrical equipment heat dissipation capacity testing system and testing method. The system comprises an air compressor, an air storage tank, an air dryer, a flowmeter, anair inlet thermometer, an air outlet thermometer, a data acquisition and analysis system, an insulated cabinet, a pipeline fitting and a standard heat source; outside air flows through the air compressor, the air storage tank, the air dryer and the insulated cabinet by the pipeline fitting; the flowmeter, the air inlet thermometer and the air outlet thermometer are mounted on the pipeline fitting;and the data acquisition and analysis system is connected with the flowmeter, the air inlet thermometer and the air outlet thermometer by hard wires. The electrical equipment heat dissipation capacity testing system and testing method implement measurement on heat dissipation capacity of electrical equipment, and are convenient to effectively determine a margin and an index of the heat dissipation capacity of the electrical equipment; and due to adoption of an intelligent and automatic technology, automatic testing and unattended operation on the heat dissipation capacity of the electrical equipment are implemented, so that testing accuracy and testing efficiency are greatly improved, and performance requirements in the aspects of ship energy consumption, noise, atmospheric environment quality and the like are improved.
Description
Technical field [0001] The invention relates to the field of electrical testing, in particular to a system and method for testing heat dissipation of electrical equipment. Background technique [0002] Air conditioning and ventilation systems, water cooling systems and air purification systems are typical energy-consuming systems for ships. The heat dissipation of electrical equipment is one of the main heat loads of the ship cabin, which directly affects the design energy consumption, cooling capacity, air volume and other parameters of the ventilation and air conditioning system, and then affects the design energy consumption, flow, pressure difference and other parameters of the water cooling system. On the other hand, most ship electrical equipment uses fans to dissipate heat, which is the main source of air noise for the equipment. The peculiar smell inside the equipment will also be dissipated in the cabin through the heat dissipation channel, which will adversely affect th...
