Title: Heat exchanger
Inventor: HARADA SHINTARO
IPC: F28F3/02
Filed: 1985-03-29
Abstract: PURPOSE:To contrive to decrease heat transfer loss in a heat exchanger, by shortening the length of thin wires in each flow path, by fitting thin wires through the pores of bulkhead bodies consisting of thin films having a number of fine pores thereon. CONSTITUTION:A number of pores 12 are punched on a bulkhead body 11 consisting of thin films which are strong enough and of low heat conductivity. The pitches among pores 12 are to be as small and as equal as possible. The bulkhead bodies 11 are separated from each other by providing flow paths 8, 8' and 9, 9' among them, and thin wires 13 are pierced through the pores 12. The thin wires 13 are inserted so as to be crossed at right angles to the flowing direction of a heat exchanger medium, and are fixed to the bulkhead bodies 11 by brazing 14. A material which has high heat conductivity such as copper wire can be used for the thin wire 13. The bulkhead bodies 11 and the thin wires 12 are housed in a case 7, constituting a heat exchanger. The heat exchanger medium in the flow path 8, 8' flows along the thin wires 13, and its heat is transferred to a heat exchanger medium in the flow path 9, 9'. Heat loss in the heat exchanger can be made small because the thin wires 13 are densely and uniformly arranged and the bulkhead bodies 11 are composed of thin films.
