Title: Heat exchanger for air conditioner
Inventor: TANAKA TATSUO
IPC: F24F1/00
Filed: 1988-12-26
Abstract: PURPOSE:To improve a mean thermal conductivity and improve a performance of a heat exchanger by a method wherein a inlet side of a zig-zag shaped heat transfer pipe having some planar fins is applied as a groove pipe and an outlet side is applied as an inner-smoothed pipe having some inner fins inserted therein. CONSTITUTION:A grooved pipe 11 having a helical groove 10 arranged at an inner circumferential surface thereof is arranged in a region ranging from a corrugated flow to an annular injection flow in case that an entire length of a thermal transfer pipe 2 is divided into six sections in a flowing direction of refrigerant, i.e. the corrugated flow, a slag flow, an annular flow, an annular atomization flow, an atomization flow and a single phase flow. An inner- smoothed pipe 13 having the inner fins 12 inserted therein is arranged at the atomization flow and the single phase flow. In case of a heat exchanger having five U-shaped thermal conducting pipes, three U-shaped thermal conducting pipes at the inlet port are of grooved pipe, and two U-shaped thermal conducting pipes are of an inner-smoothed pipe having some inner fins 12 inserted therein. Since refrigerant guided to the heat exchanger passes from the corrugated flow region to the annular atomization flow region in the grooved pipe having some groves at the inner circumferential surface, it shows a high thermal conductivity, the refrigerant passes through the inner-smoothed pipe having some inner fins inserted therein, the liquid drips are contacted with the inner fins, the refrigerant is efficiently evaporated and the thermal conductivity is improved.

Filed: 1999-11-18
Abstract: PROBLEM TO BE SOLVED: To obtain a long service life of a die and a formation of a complicated shape, in a die-forging apparatus used for die-forging by compressing and forming a blank between a punch and the die. SOLUTION: An outer tapered surface 25, in which the compressing direction of the blank S is made to the axis, is formed to the outside of the die 21. A reinforcing ring 41 having an inner tapered surface 45 in the inside, is disposed as the same axis as the above axis without fitting before compressing, so as to reinforce by fitting to this outer tapered surface 45. Almost at the same time of starting the compression to the blank with the punch 11 and the die 21, the inner tapered surface 45 of the reinforcing ring 41 is fitted in a fastening state to the outer tapered surface 25 of the die 21. Since the stress developed in the inner part of the die and tending to increase in the forming process, is offset by the compressed stress of the reinforcing ring, the amplitude of the stress in the tangential direction developed near the inner diameter of the die cavity, is reduced.
