Abstract
A method of assembling a thermosiphon system includes placing a base of an evaporator and a tube of a condensate line in a brazing fixture such that the base covers an aperture in a bottom of the tube with a bottom surface of the base abutting a precision machined surface of the brazing fixture, and simultaneously brazing the base and the tube while held by the brazing fixture to form a unitary body in a single brazing process, the unitary body including the evaporator and the condensate line.

A method of assembling a thermosiphon system, comprising:
- placing a first base of a first evaporator, a second base of a second evaporator and a tube of a condensate line in a brazing fixture such that the first base sits in a first recess in a lower portion of the brazing fixture, the second base sits in a second recess sits in the lower portion of the brazing fixture, and a portion of the tube between the first evaporator and the second evaporator abuts a section of the brazing fixture between the first recess and the second recess, wherein the first base covers a first aperture in a bottom of the tube and the second base covers a second aperture in the bottom of the tube, wherein bottom surfaces of the first base and second base abut a surface of the lower portion of the brazing fixture such that the bottom surfaces are coplanar within +/−0.05 mm, and wherein a top surface of the tube abuts an upper portion of the brazing fixture;
- and
- simultaneously brazing the base and the tube while held by the brazing fixture to form a unitary body in a single brazing process, the unitary body including the first evaporator, the second evaporator and the condensate line.
A method of assembling a thermosiphon system, comprising:
- assembling an upper portion of a thermosiphon brazing fixture into an assembly jig;
- placing a base of an evaporator and a tube of a condensate line in the brazing fixture such that the base covers an aperture in a bottom of the tube with a bottom surface of the base abutting a precision machined surface of the brazing fixture;
- assembling a lower portion of the brazing fixture over the base and the tube;
- clamping the base and the tube between the upper and lower portions of the brazing fixture within the assembly jig;
- and
- simultaneously brazing the base and the tube while held by the brazing fixture within the assembly jig to form a unitary body in a single brazing process, the unitary body comprising the evaporator and the condensate line.
