Abstract
The disclosure provides a liquid cooling heat exchanger, comprising a first cover plate, a second cover plate and a fin, the first cover plate and the second cover plate stacked on each other so as to form a chamber therebetween, the fin disposed within the chamber, the first cover plate made of a composite material, wherein there is a bonding layer between the first cover plate and the second cover plate, and the bonding layer has a melting point lower than melting points of the first cover plate, the second cover plate and the fin. The disclosure also relates to a method for making the liquid cooling heat exchanger.
Claims6
A method for making a liquid cooling heat exchanger, comprising:
- providing a first cover plate to a side of a second cover plate, wherein a chamber is formed between the first cover plate and the second cover plate;
- providing a fin in the chamber, wherein the first cover plate, the second cover plate, and the fin each are made of a composite material having a base plate coated with a bonding layer having a melting point lower than a melting point of the base plate;
- and
- melting the bonding layers of the first cover plate, the second cover plate, and the fin to form a single bonding layer between the base plates of the first cover plate and the second cover plate and a single bonding layer between the base plates of the second cover plate and the fin so as to bond the first cover plate, the second cover plate, and the fin together through a single process, wherein the bonding layer of the composite material is made of aluminum alloy with a melting point ranging between 574° C. and 599° C.
