Abstract
The invention relates to a tube bundle locating technique method for manufacturing heat exchangers and aims to solve the problem of low operating efficiency when a bundle of flat tubes are separated and inserted into a slot or a locating mechanism one by one. The invention provides a tube bundle locating fixture of a heat exchanger; the tube bundle locating fixture comprises a bracket and a group of locating pieces; and a limiting rope or a limiting spring is arranged between adjacent locating pieces respectively. When the locating pieces are in a tightening state, locating pins at the front end of the locating pieces can be simultaneously inserted into micropores of the bundle of overlapped flat tubes. And when the locating pieces are in a stretching state, the locating pieces drive the flat tube bundle to stretch and the tube pitch reaches a predetermined spacing. According to the tube bundle locating fixture, a group of tube bundles can be stretched automatically to the predetermined tube spacing and positions at one time without one-by-one manual locating, thereby improving the assembly efficiency of the tube bundle locating greatly.
Description
Technical field
The present invention relates to the manufacturing process of heat exchanger, the tube bank positioning process method during especially parallel-flow heat exchanger is made.
Background technology
Parallel-flow heat exchanger is comprised of porous flat pipe, radiating fin and header.Left header and right header are inserted respectively in the flat tube two ends, and utilization is arranged on the baffle for separating on left header and the right header and forms the series winding passage.Fin and header surface are coated with solder and brazing flux, and the anchor clamps clamping of whole core body forms by the soldering oven integral solder.Parallel-flow heat exchanger is mainly used in air conditioning for automobiles in early days, also is widely used in fields such as business air conditioner, domestic air conditioning, coolers in recent years.
Parallel-flow heat exchanger will assemble flat tube, fin and header first in process, then enters the soldering oven welding.
Existing a kind of assembly technology is, first every flat tube inserted one by one slot on the header forming framework, and then radiating fin is put into space between the flat tube.Because the spacing of flat tube and the height of radiating fin are about equally, therefore very difficult when packing fin into to the space between the flat tube, efficiency of assembling is very low.Sometimes also will utilize the elasticity of flat tube to push laterally body open certain distance, in order to pack fin into, this is operating difficulties not only with the spacing between the temporary transient expansion flat tube, and can bring hidden danger of quality.Further, along with the carrying out of fin assembling, the fin of having packed between most of flat tube will be pushed remaining body open just more difficult operation, and quality problems also more easily occur.
Existing another kind of Assembling Production technique is, first every flat tube inserted one by one locating dowel with slot to form framework, radiating fin put into the space between the flat tube again, then takes off the locating dowel of both sides and header is installed.This assembly technology, the slot spacing on the locating dowel can be slightly larger than the slot spacing on the header.Correspondingly, insert the height that tube pitch behind the flat tube also just is slightly larger than radiating fin, have certain surplus, thereby the radiating fin that is easier to pack into to the space between the flat tube.But after finishing the fin assembling, taking off the locating dowel of both sides, flat tube and fin are compressed with instrument, to eliminate the surplus in the gap between flat tube and the fin, the spacing of flat tube and the slot spacing of header are complementary, header could be installed.And for large-scale parallel-flow heat exchanger, when compressing because flat tube and fin are interference fit, the position of a lot of root flat tubes and the slot of header tend to occur certain skew, every flat tube all be inserted corresponding slot also very difficult, usually need to adjust one by one.
Above-mentioned existing Assembling Production technique, and just in the new technology of research and development, a requisite process is with a branch of flat tube separately, inserts slot or the slot on the locating dowel or other detent mechanism on the header.Present production technology, this process are by manual flat tube to be inserted slot or detent mechanism one by one, operation inconvenience, and inefficiency needs to improve process and enhances productivity.
