Improvement of air channel type in-row air conditioner and inverter cooling method

Abstract

The invention relates to an improved air flow channel type inter-row air conditioner and a cooling method for a frequency converter. A heat exchanger is vertically arranged in the middle of an air-conditioning cabinet, a hot air cavity is formed between the heat exchanger and the air return side, and cold air is formed between the heat exchanger and the air supply side The hot air cavity is provided with an electric control cabinet and a compressor. The electric control cabinet is placed close to the top of the left or right inner wall of the air conditioning cabinet, and the compressor is placed at the bottom of the inner side of the air conditioning cabinet. The heater part, the humidification part and the inverter are arranged next to the heater part. The cooling method of the inverter is air cooling, the cold air enters the air supply cavity, and the cold air enters the lower part of the horizontal plate through the ventilation hole to cool the inverter under the horizontal plate.

Description

technical field [0001] The invention relates to a row-to-row air conditioner with an improved air flow channel, belonging to the technical field of machine room air conditioners. Background technique [0002] In-row air conditioners, also known as row-to-row air conditioners, are a type of computer room air conditioners that have emerged in recent years, and are mainly used in micro-module data centers. In the micro-module data center, modules with different functions (server cabinets, power distribution unit cabinets, monitoring unit cabinets, and inter-row air conditioners) are prefabricated in their respective factories, installed and deployed on-site in the data center, placed in two columns and enclosed by aisles. According to conventional construction standards, in-row air conditioners and server cabinets are arranged side by side, and there is no room for maintenance on the sides. Routine maintenance can only be performed from the front of the air conditioner (that i...

AI Technical Summary

Problems solved by technology

The air resistance on the return air side is too large, and the air circulation volume is attenuated

Especially in the 300mm wide half-cabinet air conditioner, the conventional 300mm wide variable frequency compressor type inter-row air conditioner on the market generally has the problem of blocked air return passage and low fan operation efficiency.
