摘要:
A plate-type heat exchanger and a method for manufacturing same are provided. A plate-type heat exchanger includes a first plate and a second plate which have flange parts vertically adhered by an adhesive, respectively. The flange parts are formed in a stepped shape and may thus increase an area adhered to the first plate and the second plate.
摘要:
Adhesive compositions and methods for bonding materials with different thermal expansion coefficients is provided. The adhesive is formulated using a flux material, a low flux material, and a filler material, where the filler material comprises particulate from at least one of the two components being bonded together. A thickening agent can also be used as part of the adhesive composition to aid in applying the adhesive and establishing a desired bond thickness. The method of forming a high strength bond using the disclosed adhesive does not require the use of intermediary layer or the use of high cure temperatures that could damage one or both of the components being bonded together.

摘要:
Provided is a bonding material which can bond base materials or substrates having different linear thermal expansion coefficients, and can have heat resistance against temperatures of 300° C. or higher, vacuum airtightness and bonding strength, further which has excellent handleability and workability. The bonding material is produced by mixing, in a content ratio of 0.01 to 60 mass % (to the whole), a metal Ga, and/or at least one metal or alloy powder selected from the group consisting of a metal powder mixture of a combination of Bi and Sn or an alloy powder thereof, and a metal powder mixture of a combination of Bi, Sn and Mg or an alloy powder thereof with a Bi2O3-based glass frit powder having an average particle diameter of 200 μm or less. The bonding material may be formed in a paste form by adding a solvent thereto. This feature makes it possible to bond together substrates having different thermal expansion coefficients without causing a crack or unsticking.
