Improvements in or relating to heat exchangers

Abstract

Abstract 219,788. Brown, C. A. June 25, 1923. Honeycomb straight-tube apparatus; tubes of special section.-The tubes 1 of a heat-exchanger have bulged ends 2, 3, so that interstitial passages are left between the body portions of the tubes when assembled, and each tube is formed or furnished with projections or distance-pieces 4 substantially away from the ends for preserving the required spacing from three or more adjacent tubes. The tubes may be of circular cross-section as shown in Fig. 3, or of any other section, with bulged ends and projections of hexagonal form as shown, or of any other shape. The projections may be interrupted as shown in Fig. 10, or may be separate and applied to the outside of the tubes as in Fig. 27, and may bear against the projections on or against the body portions of adjacent tubes. Where the projections on adjacent tubes abut, the touching parts may be secured together by hollow rivets. Specification 166,930 is referred to.
