Title:

PRODUCTION OF HEAT EXCHANGER

Document Type and Number:

Japanese Patent JPH0592255

Kind Code:

A

Abstract:

PURPOSE: To prevent brazing filler metal at a joint part from melting by brazing joint members and block bodies large in heat capacity in one body in the neighborhoods of brazed parts of the joint members in a combination state.

CONSTITUTION: In a heat exchanger, an inlet tube joint member 6 and an inlet tube 4, and an outlet tube joint member 7 and an outlet tube 5 are joined by brazing in one body. Tubes 1, headers 3, corrugate fins 2 are assembled into a heat exchanger assembled body and coated with flux. The inlet tube 4 and the inlet tube joint member 6, and the outlet tube 5 and the outlet tube joint member 7 are set to the heat exchanger assembled body. Blocks 13, 14 large in heat capacity are set to the outer circumferential part and inserted into a furnace to braze flux. Since temperature is hard to rise in the neighborhoods of the joint members 6, 7, the brazing filler metal can be prevented from melting.
