Cabinet door air-cooling type constant temperature cabinet system and control method

Abstract

The invention relates to a cabinet door air-cooling type constant temperature cabinet system and a control method, and solves the problems that the hot gas radiating effect of the back portion of a cabinet is not good, the refrigeration mode is single and the service life is influenced due to continuous working of refrigeration equipment. The system comprises the cabinet. The back portion of the cabinet is provided with a cabinet door; a refrigeration unit is arranged in the lower portion of the cabinet; an external circulation unit is arranged in the upper portion of the cabinet; the back cabinet door is internally provided with an air-cooling chamber; the air-cooling chamber is internally provided with warm-air pipes; the inner side surface of the back cabinet door is provided with a plurality of inner circulation suction ports connected with the warm-air pipes; and the warm-air pipes are communicated with the refrigeration unit. The system controls the refrigeration unit, the external circulation unit and a water-cooling heat radiation device to work intermittently according to the temperature. The advantages of the system are that back cabinet door provides dual functions of heat dissipating and air returning, and the hot air is cooled before entering the refrigerating unit for refrigerating; and the refrigeration unit does not need to work all the time and is allowed to work intermittently, thereby reducing working time of the refrigeration unit and realizing the purpose of energy saving and consumption reducing.

Description

technical field [0001] The invention relates to a cooling control technology for servers, in particular to a cabinet door air-cooled constant temperature cabinet system and a control method that utilizes a rear cabinet door to perform external circulation air cooling and heat dissipation, and intermittently operates refrigeration equipment and external circulation equipment. Background technique [0002] With the widespread use of the network, especially in the cloud era, big data computing and storage are required, which increases the load on the server cabinets and puts forward higher requirements for the cooling of the cabinets. [0003] At present, the cooling and constant temperature cabinets are generally designed as a sealed structure, and compressor cooling is used to absorb the heat emitted by the server. Since the heat is mainly concentrated at the rear of the cabinet when the server is working, and because the heat dissipation system inside the server radiates fro...

AI Technical Summary

Problems solved by technology

[0005] The present invention mainly solves the problem that the general cabinet in the prior art has poor heat dissipation effect on the concentration and the rear of the cabinet, and only has a single refrigeration mode, and the continuous operation of the refrigeration equipment affects the service life. Air-cooled heat dissipation, cabinet door air-cooled constant temperature cabinet system for intermittent operation of refrigeration equipment and external circulation equipment
