Heat exchanger

Abstract

A heat exchanger includes an enclosure internally providing at least a first space and at least a second space; a first forced convection element and a cooling unit arranged in the first space; a second forced convection element and a vaporization unit arranged in the second space; and a heat transfer unit serially connecting the cooling unit and the vaporization unit to form a loop. The first and the second forced convection element work to enable forced convection of airflow, and the vaporization unit and the cooling unit together with the heat transfer unit form a convection unit. As a result, the heat exchanger has largely upgraded heat exchange efficiency.

1 . A heat exchanger, comprising:
 an enclosure internally providing at least a first space and at least a second space;   the first space having a first inlet and a first outlet, and the second space having a second inlet and a second outlet;   a first forced convection element being arranged in the first space, and having a first air-in side and a first air-out side; and the first air-in side being located close to and aligned with the first inlet;   a cooling unit being arranged in the first space to face toward the first outlet;   a second forced convection element being arranged in the second space, and having a second air-in side and a second air-out side; and the second air-in side being located close to and aligned with the second inlet;   a vaporization unit being arranged in the second space to face toward the second outlet; and   a heat transfer unit serially connecting the cooling unit and the vaporization unit.   
     
     
         2 . The heat exchanger as claimed in  claim 1 , wherein the first and the second forced convection element are respectively a centrifugal fan. 
     
     
         3 . The heat exchanger as claimed in  claim 1 , wherein the cooling unit is selected from the group consisting of a heat sink and a radiating fin assembly. 
     
     
         4 . The heat exchanger as claimed in  claim 1 , wherein the heat transfer unit is selected from the group consisting of a heat pipe and a flat heat pipe. 
     
     
         5 . The heat exchanger as claimed in  claim 1 , wherein the vaporization unit is selected from the group consisting of a vapor chamber and a flat heat pipe. 
     
     
         6 . The heat exchanger as claimed in  claim 1 , wherein the heat transfer unit is internally provided with a capillary structure. 
     
     
         7 . The heat exchanger as claimed in  claim 1 , wherein the enclosure includes a first enclosure and a second enclosure, and the first and the second enclosure being correspondingly closed to each other to define the first and the second space, respectively. 
     
     
         8 . The heat exchanger as claimed in  claim 1 , wherein the enclosure is internally provided with a partition plate to define the first and the second space in the enclosure.
