Title:
COOLING APPARATUS
Document Type and Number:
Japanese Patent JP2950236
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To diagnose cause of an abnormality in a structure wherein heat absorbed from a high temperature space is radiated into a low temperature space by means of a heat exchanger and a low temperature fluid is made to pass into the low temperature space by a cooling fan.
SOLUTION: A heat exchanger 16 is installed in a fluid partition wall 7 for partitioning the interior of an apparatus main body 4, and heat exchange is carried out by the heat exchanger 16 between a high temperature space 8 communicating with the interior of a housing 4 and a low temperature space 9 communicating with outside. A low temperature side fan motor 25 is driven by a driver 27 to make outside air pass into the low temperature space 9 so that cooling efficiency of the heat exchanger 16 is enhanced. The driver 27 transmits rotation and load of the low temperature side fan motor 25 to a control device 21. The control device 21 determines contents of an abnormality according to the rotation and load of the low temperature side fan motor 25 and the contents of the abnormality are transmitted.
