Evaporator with heat dissipating fins and refrigerant heat dissipating apparatus using the same

Abstract

An evaporator with heat dissipating fins and a refrigerant heat dissipating apparatus using the same are provided herein and the refrigerant heat dissipating apparatus comprises the evaporator, a condenser, two refrigerant tubes connected between the evaporator and the condenser and a refrigerant filled into the evaporator body. When the evaporator body absorbs heat, the refrigerant absorbs heat and is converted to the gaseous state. The refrigerant in the gaseous state flows upward and conducts heat to a top of the evaporator body. The heat dissipating fins conduct heat quickly to condense most of the refrigerant in the gaseous state back to the liquid state to absorb heat again. The rest of the refrigerant in the gaseous state passes through the condenser via the first refrigerant tube to be the liquid refrigerant. The liquid refrigerant flows back to the evaporator body via the second refrigerant tube to absorb heat again.

What is claimed is: 
     
         1 . An evaporator with heat dissipating fins, comprising:
 an evaporator body having:
 an evaporating chamber disposed within the evaporator body; 
 a heat dissipating plate disposed at a bottom of the evaporator body; 
 a refrigerant outlet disposed at a top of the evaporator body and communicating with the evaporating chamber; and 
 a refrigerant inlet disposed at a lateral side of the evaporator and communicating with the evaporating chamber; and 
   a plurality of heat dissipating fins arranged at a peripheral surface of the evaporator body and heat conductively connected to the evaporator body.   
     
     
         2 . A refrigerant heat dissipating apparatus, comprising:
 an evaporator with heat dissipating fins, the evaporator including:
 an evaporator body having:
 an evaporating chamber disposed within the evaporator body; 
 a heat dissipating plate disposed at a bottom of the evaporator body; 
 a refrigerant outlet disposed at a top of the evaporator body and communicating with the evaporating chamber; and 
 a refrigerant inlet disposed at a lateral side of the evaporator and communicating with the evaporating chamber; and 
 
 a plurality of heat dissipating fins arranged at a peripheral surface of the evaporator body and heat conductively connected to the evaporator body; 
 a condenser including:
 two condensing tubes horizontally disposed and spaced at an interval; 
 a plurality of heat dissipating tubes vertically disposed and spaced at intervals, and the heat dissipating tubes disposed from top to down between the two condensing tubes and parallel to each other; 
 a plurality of heat dissipating elements distributed on outer surfaces of the heat dissipating tubes and contacting the outer surfaces of the heat dissipating tubes; 
 
 a first refrigerant tube, and one end of the first refrigerant tube connected with the refrigerant outlet at the top of the evaporator body and another end of the first refrigerant tube obliquely extended upward and connected with a top section of one of the two condensing tubes at one side of the condenser; 
 a second refrigerant tube, and one end of the second refrigerant tube connected with the refrigerant inlet at the lateral side of the evaporator body and another end of the second refrigerant tube laterally extended and connected with a bottom section of the other one of the two condensing tubes at another side of the condenser so as to form a closed refrigerant recurring cycle by the evaporator, the condenser, the first refrigerant tube and the second refrigerant tube; and 
 a refrigerant filled into the refrigerant recurring cycle and flowing within the refrigerant recurring cycle in accordance with a liquid and gaseous state conversion. 
   
     
     
         3 . The refrigerant heat dissipating apparatus as claimed in  claim 2 , wherein the heat dissipating elements are wavy sheets.
