AIR FLOW CONTROLLER

摘要

PURPOSE:To always supply an optimum air flow to a cooling subject by obtaining a correcting air flow from a temperature and a load current and the correcting the air flow decided previously based on said correcting air flow to decide the air flow to be supplied to the cooling subject. CONSTITUTION:The cooling air is supplied via a cooling air blower 13 and a temperature and a load current are detected by a temperature detector 14 and a current detector 15 respectively while a cooling subject 11 is working. The load current detected by the detector 15 is sent to a current/temperature function generating means 16 for extraction of an optimum temperature of the subject 11 corresponding to the load current. This optimum temperature is compared with the temperature detected by the detector 14 and an optimum correcting air flow is acquired out of the relations between the temperatures and the correcting air flow turned previously into functions based on the deviation between said two temperatures. Based on this correcting air flow set by an air flow setting means 20 is corrected. Thus it is possible to quickly supply an optimum air flow to the subject 11 in response to the temperature and the load current which change momentarily and to set the subject 11 at a desired temperature.
