Information handling apparatus, control apparatus, and installation

Abstract

An information handling apparatus includes a chassis installed a plurality of electric parts of the information handling apparatus, having a pair of openings on opposite sides for allowing an incoming and outgoing air flow for cooling down an inside of the information handling apparatus, a pair of temperature detectors for detecting temperature at each of the openings, a fan installed in the housing for generating airflow between the openings, the fan being capable of reversibly switching airflow direction, and a controller for performing switching of the air flow direction by the fan so that the fan generates the airflow from one of the openings at which a detected with lower temperature is detected as compared with the other of the openings.

1 . An information handling apparatus comprising:
 a chassis installed a plurality of electric parts of the information handling apparatus, having a pair of openings on opposite sides for allowing an incoming and outgoing air flow for cooling down an inside of the information handling apparatus;   a pair of temperature detectors for detecting temperature at each of the openings;   a fan installed in the housing for generating airflow between the openings, the fan being capable of reversibly switching airflow direction; and   a controller for performing switching of the air flow direction by the fan so that the fan generates the airflow from one of the openings at which a detected with lower temperature is detected as compared with the other of the openings.   
     
     
         2 . A control apparatus for controlling a fan installed in a housing for generating airflow between the openings, the fan being capable of reversibly switching airflow direction, the housing accommodating a plurality of information handling apparatus and having a pair of openings on opposite sides for allowing an incoming and outgoing air flow for cooling down the information handling apparatus, the fan control apparatus comprising:
 a pair of temperature detectors for detecting temperature at each of the openings;   a controller for performing switching of the air flow direction by the fan so that the fan generates the airflow from one of the openings at which a detected with lower temperature is detected as compared with the other of the openings.   
     
     
         3 . The control apparatus according to  claim 2 ,
 wherein the a housing is installed in an installation which installed an air-conditioner.   
     
     
         4 . The control apparatus according to  claim 3  wherein:
 the installation has a plurality of the housings which are arranged in the plurality of rows, and   the air-conditioner has a plurality of vents and air inlets which are arranged between the rows, the plurality of the vents and the air inlets having respectively flaps which are openable and closable.   
     
     
         5 . An installation comprising:
 a plurality of information handling apparatuses including respectively;
 a chassis installed a plurality of electric parts of the information handling apparatus, having a pair of openings on opposite sides for allowing an incoming and outgoing air flow for cooling down an inside of the information handling apparatus, 
 a pair of temperature detectors for detecting temperature at each of the openings, 
 a fan installed in the housing for generating airflow between the openings, the fan being capable of reversibly switching airflow direction, and 
 a controller for performing switching of the air flow direction by the fan so that the fan generates the airflow from one of the openings at which a detected with lower temperature is detected as compared with the other of the openings; and 
   an air conditioning apparatus for air conditioning within the installation.   
     
     
         6 . The installation according to  claim 5 , further comprising
 a plurality of the housings each for accommodating a plurality of information handling apparatus, the plurality of the housings arranged in the plurality of rows;   wherein the air conditioner has a plurality of vents and air inlets which are arranged between the rows, the plurality of the vents and the air inlets having respectively flaps which are openable and closable.
