Fluid cooling apparatus

Abstract

A fluid cooling apparatus with a heat exchanger device ( 3 ), which cools heated fluid under the action of a cooling air stream passed through it is characterized in that an air filter arrangement ( 21, 43 ) is provided upstream of the heat exchanger device ( 3 ) in the flow path of the cooling air stream.

1 . A fluid cooling apparatus with a heat exchanger ( 3 ), which cools heated fluid through the action of a cooling air stream passed through it, characterized in that an air filter arrangement ( 21 ,  43 ) is provided upstream of the heat exchanger device ( 3 ) in the flow path of the cooling air stream. 
     
     
         2 . The fluid cooling apparatus according to  claim 1 , characterized in that an air-flow apparatus is provided that can be operated by a motor-actuated fan ( 11 ) that generates the cooling air stream. 
     
     
         3 . The fluid cooling apparatus according to  claim 1 , characterized in that the heat exchanger device ( 3 ) includes a plate-shaped cooling unit, approximately in the shape of a cellular radiator, and in that the air filter arrangement ( 21 ,  43 ) constitutes a filter area upstream of the air inlet area ( 19 ). 
     
     
         4 . The fluid cooling apparatus according to  claim 1 , characterized in that the filter area is formed by a filter mat ( 23 ,  37 ,  39 ,  41 ) that is held inside a frame ( 31 ) adjusted to the air inlet area ( 19 ) of the cooling unit. 
     
     
         5 . The fluid cooling apparatus according to  claim 1 , characterized in that the frame ( 31 ) includes at least one grate ( 33 ) that rests as a support structure on one side of the filter mat ( 23 ,  37 ,  39 ,  41 ). 
     
     
         6 . The fluid cooling apparatus according to  claim 1 , characterized in that there is provided an air filter arrangement in the form of a belt-type filter apparatus ( 43 ) that includes a filter belt ( 45 ) constituting the filter surface that can be moved upstream of the air inlet area ( 19 ). 
     
     
         7 . The fluid cooling apparatus according to  claim 1 , characterized in that a signaling device ( 25 ) is present that detects the contamination of the filter area based on the reduction of the flow rate of the cooling air stream that passes through the filter area and issues an alert signal. 
     
     
         8 . The fluid cooling apparatus according to  claim 1 , characterized in that the movement of the filter belt ( 45 ) of the belt filter arrangement ( 43 ) is controlled such by the signaling device ( 25 ) that contaminated belt sections of the filter belt ( 45 ) are replaced with fresh belt sections. 
     
     
         9 . The fluid cooling apparatus according to  claim 1 , characterized in that the belt filter arrangement ( 43 ) includes a belt transportation device that transports the contaminated belt sections through the flow path ( 9 ) that is located downstream of the cooling unit ( 3 ) in such a manner that any contaminations ( 51 ) are blown off by the cooling air stream and the cleaned belt sections are returned to the air inlet area ( 19 ).
