Active micro cooler

Abstract

The present invention relates to an active micro cooler comprising: an evaporator which, directly attached to a heat source, vaporizes refrigerant; a compressor which inhales and compresses vaporized refrigerant gas; a condenser which condenses compressed refrigerant gas for condensed refrigerant to release heat; a conduit which directs condensed refrigerant to the evaporator; and a expansion valve which, mounted on the conduit, expands condensed refrigerant. The evaporator and the condenser each comprises a heat transfer enhancement device which is mounted on a plate element having walls on the circumference of the element and several channel connectors for transmitting refrigerant. The active micro cooler according to the present invention has a comparatively simple structure and has a greater cooling capacity than a hand cooler.

1 . A active micro-cooler, comprising: 
 a evaporator which is directly attached to the heat source and vaporizes refrigerant;    a compressor which inhales and compresses the vaporized refrigerant gas;    a condenser which condenses the compressed refrigerant gas and discharges heat from the refrigerant;    a conduit which directs condensed refrigerant to the evaporator; and    a expansion valve which is mounted on conduit and expands the condensed refrigerant.    
     
     
         2 . The active micro-cooler according to  claim 1 , wherein said evaporator, said compressor and said condenser are layered in sequence, to form laminated structure.  
     
     
         3 . The active micro-cooler according to  claim 1 , wherein said evaporator includes: 
 a heat transfer channel on a sheet member which has a surrounding wall around it; and    a certain number of connecting channels which enable the vaporized refrigerant gas to move to said compressor.    
     
     
         4 . The active micro-cooler according to  claim 1 , wherein said compressor including: 
 a certain number of compression means, said compression means are arranged symmetrically on    a sheet member, compress the refrigerant beneath said sheet member and then send the compressed refrigerant to the upper side of said sheet member;    a center hole, which enables the condensed refrigerant from the condenser to move toward said evaporator.    
     
     
         5 . The active micro-cooler according to  claim 4 , wherein said compression means comprising: 
 a pressure chamber, which is located at the inner part of said second compression means;    a vibrating plate, which comprises the outer wall of said pressure chamber and can be deformed to change the volume of said pressure chamber;    a inlet valve, which can be opened and closed for the inhalation of refrigerant into the pressure chamber; and    a outlet valve, which can be opened and closed for the exhaustion of refrigerant out of the pressure chamber.    
     
     
         6 . The active micro-cooler according to  claim 5 , wherein, said vibrating plate operated by symmetrically arranged a certain number of piezo-actuators; and said inlet valve and said outlet valve operated by piezo-actuators which are disposed on said inlet valve and said outlet valve respectively  
     
     
         7 . The active micro-cooler according to  claim 1 , wherein, said condenser including: 
 a certain number of connecting channels which enable the vaporized refrigerant gas to move to said condenser;    a heat transfer channel on a sheet member which has a surrounding wall around it; and    a center hole, which enables the condensed refrigerant from the condenser to move toward said evaporator.    
     
     
         8 . The active micro-cooler according to  claim 4 , wherein, said conduit is connected to the center holes which are formed on said compressor and condenser.  
     
     
         9 . The active micro-cooler according to  claim 5 , wherein, said conduit is connected to the center holes which are formed on said compressor and condenser.  
     
     
         10 . The active micro-cooler according to  claim 6 , wherein, said conduit is connected to the center holes which are formed on said compressor and condenser.  
     
     
         11 . The active micro-cooler according to  claim 7 , wherein, said conduit is connected to the center holes which are formed on said compressor and condenser.
