  • Fig ⁇ 2 is f a en a Ver- 7 orators of this type with sheet-metal walls of tical section through a wall of the evaporator double thickness, the two walls being formed shown in Fig. 1;
  • Fig. 3 is a generally horizontal to provide between them a space forthe refrig- 1 section through one corner of the ⁇ evaporator erant. In' some cases, this space has taken the shown in Fig. 1;
  • Fig. 4 is an elevation illustrating form of a helical or retroverted channel successivethe position occupied by the evaporator of Fig.
  • evaporator, 1 or the evgpomtor with walls of material of the strip II is brought into contact double-thickness in such a way that between the 5 with the side indicated at m and walls there is provided a continuous refrlgerantsecured thereto desirably by welding tr??
  • openings l1 are closed.
  • the openings l1 are provided in the bottoms of recesses l8 formed by inward displacement of the material of the strip each opening I! being somewhat smaller in diameter than its associated recess.
  • a disc IQ of suitable material may be placed in the recess l8 and secured therein as by welding, soldering, or brazing.
  • An evaporator such as that described above possesses a continuous helical refrigerant-passage
  • Cross-flow between adjacent turns of the helical passage isprevented, and all the refrigerant is compelled to flow through the passage from one end thereof to the other. ther, the metal of which the evaporator is formed is protected against corrosion by the zinc with which it is coated.
  • the device comprises two sheet-metal plates 2
  • the plate 22 is formed with spaced, parallel ribs 23 each ,of which extends inwardly from one end of the plate and terminates short of the opposite end to leave a short unribbed portion 24.
  • the portions 24 are arranged alternately at opposite ends of the plate 22.
  • the plate 22 After the plate 22 has been formed in the manner described it is brought together with the plate 2
  • the assembly thus formed is dipped in the sealing compound while held in positionwith the ribs 23 extending generally vertically, the sealing compound entering the channels at the lower Furends thereof beneath the unribbed portions 24 of the plate 22 and displacing air which escapes from the upper ends of the channels.
  • excess sealing compound is drained off, and the edges of the unribbed portions 24 are brought into engagement with and secured to the plate 2
  • a process of making a heat-exchanger comprising iorming a plate of flexible material to provide a series of parallel ribs separated by opentopped channels, covering the open tops of said -channels with a second plate engaging said ribs While leaving openings at the ends of said channels, securing said second plate to said ribs, im-' mersing the assembly in a bath of liquid sealing material with some of said openings at the bottom of the assembly and others at'the top and with the channels extending generally vertically between the upper and lower openings whereby the liquid sealing material may enter the lower openings and fill the channels while air escapes from the upper openings, removing the assembly.
  • a process of making a heat exchanger which comprises forming aplate of flexible material with a series of parallel spaced ribs separated by open-topped channels, each of said ribs extending inwardlyfrom one end of they plate and terminating short of the other end to leave an unribbed portion, said unribbed portions being disposed alternately at opposite ends of the plate, covering the open tops of said channels with a second plate spaced from said unribbed portions of the first plate to leave openings at the opposite ends of each channel, securing said second plate to said ribs, immersing the assembly in a bath of liquid sealing material with the ribs extending generally vertically whereby liquid'sealing material may' enter the channels through the openings at the lower ends thereof while air escapes from the channels through the openings at the upper ends thereof, removing the assembly from the bath to drain excess sealing material from the channels through the openings at the lower ends thereof while air enters the openings at the upper ends thereof, bending the edges of said unribbed portions into association with said second
  • openings is approximately sealing material may enter the lowermost of said openings while air escapesthrough the uppermost openings, removing the assembly from the bath of liquid seaiing compound to drain any excess sealing'compound through the lowermost of said openings while air enters the uppermost of said openings, and subsequently closing said openings.
