Abstract

The invention discloses a stainless steel plate fin type radiator and a processing method thereof. The radiator comprises two side plates which are arranged at intervals, a plurality of long sealing strips which are arranged at equal intervals are arranged between the side plates, the length of each long sealing strip is the same as that of each side plate, a fin is arranged between every two adjacent long sealing strips, and short sealing strips are arranged at the two ends of each fin; the fin comprises the following raw materials of 85-100 parts of Fe, 0.05-0.1 part of C, 0.02-2 parts of Si, 0.1-5 parts of Mn, 0.01-0.02 parts of S, 1-5 parts of Ni, 12-15 parts of Cr, 0.1-2 parts of Cu, 0.2-3 parts of Al, 0.001-0.005 part of Ti, 0.01-0.05 part of P, 0.01-0.1 part of Mg, 0.01-0.3 part ofNb and 0.01-0.1 part of W. Compared with the traditional fin, the finished fin obtained by adopting the scheme of the invention has the advantages that the strength and the thermal stability are greatly improved, and the fin does not deform due to the fact that the radiator is in a high-temperature state for a long time.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a stainless steel plate-fin radiator and a processing method thereof. Background technique [0002] There are three types of radiators: plate-plate type, shell-and-tube type, and plate-fin type. In the case of the same volume, the plate-fin type radiator is the radiator with the highest heat dissipation efficiency and the lightest weight. [0003] The materials of plate-fin radiator mainly include aluminum alloy, stainless steel, etc. At present, aluminum alloy plate-fin radiator has been widely used in machinery, chemical industry, automobile and other fields. Compared with the aluminum alloy plate-fin radiator, the stainless steel plate-fin radiator has the advantages of high operating temperature (the melting point of stainless steel is 1750°C, and the melting point of aluminum alloy is 650°C), and it has good corrosion resistance. And other fields, stainless st...
