Heat exchanger having micro-channels

Abstract

Disclosed is a heat exchanger configured by laminating layers having micro-channels by adapting a micromachining, wherein the micro-channels having uniform length and cross section are constructed within a heat exchanger body in a curved outer shape, thereby minimizing deviation for each channel and improving heat transfer efficiency.

1 . A heat exchanger having micro-channels comprising:
 a heat exchanger body having a plurality of layers laminated, each layer having a plurality of micro-channels;   a high temperature fluid inlet body and a low temperature fluid outlet body detachably connected to one end portion of the heat exchanger body; and   a low temperature fluid inlet body and a high temperature fluid outlet body detachable connected to another end portion of the heat exchanger body,   wherein both side surfaces defining a width of the heat exchanger body have a first curvature profile and a second curvature profile in parallel to the first curvature profile.   
     
     
         2 . The heat exchanger of  claim 1 , wherein the heat exchanger body comprises:
 a hot side layer having a plurality of first micro-channels in parallel to one another, high temperature fluid flowing within the plurality of first micro-channels; and   a cold side layer having a plurality of second micro-channels in parallel to one another, low temperature fluid flowing within the plurality of second micro-channels.   
     
     
         3 . The heat exchanger of  claim 2 , wherein the first and second micro-channels respectively comprise n micro-channels, n≧2,
 wherein i th  (i=natural number) channel of the channels may include an inlet portion having a length X i , a curved portion having a length W i  and an outlet portion having a length Y i ,   wherein X i , Y i  and W i  are constructed to meet the following equation.
     X   i   +Y   i   +W   i =Constant 
   
     
     
         4 . The heat exchanger of  claim 3 , wherein a width between one curved portion and another curved portion adjacent thereto, among the curved portions, is constantly maintained in a lengthwise direction. 
     
     
         5 . The heat exchanger of  claim 4 , wherein the curved portion is configured in a wavy form.
