Benefits of technology

[0008]The primary objective of the present invention is to provide an improved liquid cooled heat dissipator having a fan to increase the heat dissipating efficiency.
[0009]In order to accomplish the foregoing objective, the liquid cooled heat dissipator of the present invention has multiple channels, multiple rows of heat dissipating fins each received in a corresponding one of the channels, multiple tin alloy welding layer provided on two opposed inner side faces of each of the channels so as to secure each row of heat dissipating fins inside the corresponding channel and between a securing plate and an outer side face of a top most channel and a bottom most channel such that the overall heat exchange rate is increased.

Problems solved by technology

To further analyze the characteristics of bronze, it is learned that although the metal, bronze, has great heat absorption efficiency, it does not have high heat dissipating capability.
Eventually, the overall heat dissipating efficiency of the liquid cooled heat dissipator is not as good as expected and can not be improved.

Abstract

A liquid cooled heat dissipator includes water channels, rows of heat dissipating fins respectively received in a corresponding one of the water channels and each heat dissipating fin having a ridge and a trough, a first water tank mounting seat having first openings defined to respectively communicate with the water channels, a second water tank mounting seat opposite to the first water tank mounting seat and having multiple second openings respectively communicating with the water channels, a first water tank in the first water tank mounting seat and a second water tank mounted in the second water tank mounting seat for turning water flow in the water channels.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a liquid cooled heat dissipator, and more particularly to liquid cooled heat dissipator having multiple aluminum fins and a tin alloy welding layer formed inside the heat dissipator to enhance heat dissipating efficiency.[0003]2. Description of the Prior Art[0004]An air cooled heat dissipator mainly is using air as the heat dissipating medium to dissipate heat absorbed by fins of the heat dissipator. To enhance the heat dissipating efficiency, aluminum is adopted to be the material for making the fins, which is light weight and having a feature of fast heat dissipating capability.[0005]For a liquid cooled heat dissipator, it is noted that the heat dissipating ability depends on the heat exchange rate between the liquid and the fins. To increase the heat exchange rate, bronze is normally the best choice to make the water channel and the fins in the liquid cooled heat dissipator.[0006]To f...
