The invention discloses a vacuum brazing technological method for a core part of a plate-fin type aluminum heat exchanger. A vacuum brazing technology adopted for brazing the core part of the plate-fin type aluminum heat exchanger comprises the steps of:laminating and assembling a plurality of heat-exchanger core parts with consistent side pate dimensions in a height direction and are fixed
Feb 23, 2018 · A plate type heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. This has a major advantage over a conventional heat exchanger in that the fluids are exposed to a much larger surface area because the fluids spread out over the plates. This facilitates the transfer of heat, and greatly increases the speed of the temperature change. finned tube heat exchangers, fin heat exchanger, heat Feb 23, 2018 · Finned Tube Heat Exchangers is a type of heat exchanger design that uses plates and finned chambers to transfer heat between fluids. It is often categorized as a compact heat exchanger to emphasise its relatively high heat transfer surface area to volume ratio. The plate-fin heat exchanger is widely used in many industries, including the
The invention discloses an aluminum plate-fin type heat exchanger and a vacuum braze welding process method thereof, which comprises a structure of the aluminum plate-fin type heat exchanger and the vacuum braze welding process method. The invention uses a dislocated rectangular fin to substitute for a triangular fin structure in a high-temperature fluid medium passage.
