Computer room air conditioner fan mounting mechanism

Abstract

The invention discloses a computer room air conditioner fan mounting mechanism which comprises a frame of a two-layer structure and a fan. The upper layer of the frame is used for mounting an evaporator. The lower layer of the frame is a fan mounting space. The fan is fixed to the fan mounting plate. The two side edges of the fan mounting plate are provided with guide rails and can move horizontally along the frame. Stand columns of the frame are further provided with guide rails. Bolt mounting holes are formed in positions of different heights. The fan mounting plate can vertically move along the guide rails on the stand columns to adjust the height. The periphery of the fan mounting plate is further provided with a flexible sealing strip, and the periphery of the fan mounting plate and the periphery of the frame form elastic sealing. According to the computer room air conditioner fan mounting mechanism, the vertical height of the fan can be adjusted according to requirements, drawer type mounting can be achieved, and quick mounting and overhauling are achieved; meanwhile the dead corners generated when the air flow penetrates through the evaporator can be reduced as far as possible, and the heat change efficiency of the evaporator is achieved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration of air-conditioning units, and in particular relates to the improvement of the installation technology of an air-conditioning fan in a machine room. Background technique [0002] After decades of rapid development, communications, IT, mobile Internet and big data services have all grown dramatically. As the central system, the IDC data center's requirements for computer room air conditioners are no longer the most basic safety and reliability, but high efficiency and energy saving have gradually become the focus. The main performance parameters of computer room air conditioners include cooling capacity, energy efficiency ratio, sensible heat ratio, air volume and so on. The methods to improve its performance coefficient are: 1), optimize the airflow organization, reduce the air circulation resistance, increase the air volume, reduce the energy consumption of the fan, increase the cooling ca...

Problems solved by technology

However, there are the following defects: (1) The V-shaped arrangement of the evaporator coil is an inverted "V" shape relative to the airflow direction. However, as it gets closer to the V-shaped two-foot area, the passing efficiency of the airflow becomes smaller, thus forming a dead angle, thereby affecting the cooling effect; (2) The cooling water formed during the heat exchange must be collected at the sharp corner of the V-shape , at this time, the cooling water collecting plate located under the V-shaped sharp corner will also form resistance to the passing airflow, affecting the cooling effect; (3) and the collection pipe of the evaporator coil arranged in a V-shaped arrangement is also arranged in the airflow channel, The cross-sectional area of ​​the airflow is larger when it enters the air intake space, and the cross-sectional area becomes smaller when it flows through the evaporator, and the flow area after it exits the evaporator increases, resulting in a large loss of air pressure in the airflow, which in turn affects the cooling effect of the airflow
