Header unit and heat exchanger having the same

Abstract

A header unit having an improved assembly method of a body and a header and a heat exchanger having the same, capable of preventing a body from being incompletely bonded to a cover at an inner side of the header as a result of the instability of a manufacturing process, and thus capable of preventing the leaking of the refrigerant in between two tanks at an inside of the header. The heat exchanger includes a body, and a cover coupled to the body, wherein the body includes a base part forming a bottom surface of the body, and a middle partition protrudedly formed from the base part, and the cover includes a coupling groove to which the middle partition of the body is coupled while passing through the coupling groove.

         9 . The header unit of  claim 1 , wherein:
 the middle partition has a width of about 2 mm or above and about 3 mm or below.   
     
     
         10 . The header unit of  claim 1 , wherein:
 the base part of the body comprises a mounting groove;   the cover comprises a support part; and   at least one portion of the support part of the cover is inserted into the mounting groove.   
     
     
         11 . The header unit of  claim 10 , wherein:
 the mounting groove of the body comprises an outside partition part and an inside partition part that are protrudedly formed from the base part.   
     
     
         12 . The header unit of  claim 11 , wherein:
 the outside partition part is formed by being protruded to be higher than the inside partition part.   
     
     
         13 . A heat exchanger, comprising:
 a first header unit to which a refrigerant inlet pipe and a refrigerant outlet pipe are connected;   a second header unit disposed in parallel to the first header unit while being spaced apart from the first header unit by a predetermined distance;   a plurality of flat-type micro-channel tubes arranged in a front row and a rear row in between the first header unit and the second header unit, the plurality of flat-type micro-channel tubes having a micro channel; and   a plurality of plate-shape fins provided with slots arranged in a front row and a rear row, so that the flat-type micro-channel tubes of the front row and the rear row are inserted into the slots,   wherein each of the first header unit and the second header unit comprises:
 a body; and 
 a cover coupled to the body, 
 wherein the body comprises: a middle partition configured to divide the first header unit into a first header and a second header, and to divide the second header unit into a third header and a fourth header, while the cover comprises a coupling groove; and 
 the middle partition is coupled to the coupling groove of the cover. 
   
     
     
         14 . The heat exchanger of  claim 13 , wherein:
 the middle partition comprises a first middle partition extended from a base part that forms a bottom surface of the body, and a second middle partition protrudedly formed from the first middle partition.   
     
     
         15 . The heat exchanger of  claim 14 , wherein:
 at least one portion of the second middle partition is protruded by passing through the coupling groove of the cover.
