Fin-pipe shaped radiator specially adapted to a semiconductor chilling unit and the method of making same

Abstract

This invention relates to a radiator and its preparation method, and especially refers to a fin-pipe shaped radiator specially applied to semiconductor chilling unit and its preparation method. This radiator consists of vertical pipe and upper & lower horizontal pipe (both ends are blocked) welded into the heat radiation chamber, and the evaporator connected through pipeline with axially extending fins distributed on the external surface of the horizontal pipe and the vertical pipe in an angle “α” at the joint within the range of 0°<α≦90°. The main components are manufactured into sections by extruding, punching or other machining techniques and then soldered into a radiator. It has overcome the disadvantages of various and numerous welding points, complicated techniques and so on in existing manufactures, and has realized an industrialized batch production upon simple and reliable techniques.

1 . A fin-pipe shaped radiator specifically adapted to a semiconductor chilling unit, comprising:
 one or multiple vertical pipes with two open ends;   a upper and a lower horizontal pipe with two closed ends and one or multiple through-holes in the pipe;   wherein said vertical pipe are connected to said horizontal pipes by welding said open ends with said through-holes into a heat radiation chamber;   an evaporator connected to said horizontal pipes via said through-holes via one or multiple pipelines; and   multiple bar fins applied axially along the pipe on an external surface of said horizontal pipe and said vertical pipe.   
   
   
       2 . The fin-pipe shaped radiator of  claim 1 , wherein the horizontal pipe is made of section material comprising:
 an arched plate forming a U shape trough with a side slot and two ends;   a cover panel with through-holes; and   two end caps;   where said horizontal pipe is formed by fixing said cover panel on said side slot of said arched plate and said closed ends are formed by fixing said end caps to the two ends of said arched plate.   
   
   
       3 . The fin-pipe shaped radiator of  claim 1 , wherein the bar fins on the external surface of the horizontal pipe and vertical pipe extend radially. 
   
   
       4 . The fin-pipe shaped of  claim 1 , wherein the bar fins are integrated with said horizontal pipe or vertical pipe. 
   
   
       5 . The fin-pipe shaped radiator of  claim 1 , wherein the horizontal pipe and vertical pipe are connected with said pipelines by welding. 
   
   
       6 . The fin-pipe shaped radiator of  claim 1 , wherein said horizontal pipe or said vertical pipe is provided with a pressure release valve. 
   
   
       7 . The fin-pipe shaped radiator of  claim 1 , wherein said upper and lower horizontal pipes are provided with an inspection hole with lens for inspecting said heat radiation chamber. 
   
   
       8 . A method for making said fin-pipe shaped radiator as in  claim 2  comprising following steps:
 a. making said vertical pipe and said arched plate using extruding shaping technology; making two side indentations on said cover panel by extruding technique or using slotting machine and applying welding dressing on said indentations; forming said through-holes with flagings on said cover panel with welding dressing applied; cutting said vertical pipe, said arched plate and said cover panel with side indentations into predetermined length;   b. making said end caps with grooves by punch forming a plate material coated with welding dressing;   c. assembling said arched plate, said cover panel and said end caps into said horizontal pipe; jointing the horizontal pipe and vertical pipe through said through-holes by a fixing means and then putting into a soldering furnace, heating to melt the welding dressing so that the horizontal pipe with through-holes can be directly welded with the vertical pipe.   
   
   
       9 . The method of  claim 8 , further comprising:
 forming an opening for a pressure release valve on said horizontal or vertical pipes and fixing said pressure release valve into said opening;   forming an inspection hole with a transparent lens on said end cap and equipping said lens on said inspection hole.
