Abstract (en)

[origin: JPH0351695A] PURPOSE: To simply assemble a heat exchanger with each member and each thin sheet laboratory dish, by connecting mutually complementary thin sheet dishes, and forming two assembly pipes and a matrix composed of a plurality of side small pipe layers communicating with the assembly pipe. CONSTITUTION: A thin sheet laboratory dish 1 is formed mainly into a frame shape, and has two holes 2a, 2b for forming an assembly tube in the centers of opposing longer side surfaces. Many parallelly disposed longitudinal slits are crossed by a connection bridge 3 in a predetermined distance. Hereby, a longitudinal stripe 5 is formed to form a side wall of a side surface small tube up to a longer side surface of the frame from the holes 2a, 2b. There is formed a recessed groove in the thin sheet dish 1 at the position of the longitudinal stripe 5 for forming the side surface small tube having a substantially elliptic cross section. Thus, a heat exchanger is simply assembled from each member and each thin sheet dish.
