The liquid gas of HTHP is produced after the compression of overcompression machine, by being changed into the liquid of cryogenic high pressure after condenser radiating condensation,
It is collected into header and is discharged to outdoor again.
Common header species is various on the market, a kind of collection for heat exchanger proposed such as patent CN102449425A
Flow tube, there is bottom, lid, both positions are relative, and overall is in arc type, it is characterised in that can reduce the header of two-piece type
Weight, and thus reduce the pressure loss in terms of cost and cooling agent.A kind of collection that and for example patent CN103148729A is proposed
Flow tube, the header include axially extending inner chamber body and multiple axially extending separate parts, it is characterised in that header by
Multiple individually parts are formed, the problem of improving the two phase flow distribution of heat exchanger, and improve heat exchange property.Also patent
CN106403401A discloses a kind of header used for automobile air conditioning, including header, feed tube, drain pipe, it is characterised in that knot
Structure is simple, easily manufactured, to reduce processing cost, assembling simple.
But in the header feature disclosed in above-mentioned patent, it can not ensure while improving heat exchange property simple in construction with making
Make conveniently, and the unstability that directly welding heat radiating flat tube is exposed on header fails have solution or suppression side always
Case.In addition, heat radiating flat tube is directly welded at by most manufacturers with being all not added with medium with header by groove on the market
Together, the stability of welding procedure, the compatibility of header and heat radiating flat tube, degree of fiting is caused to fail to have breakthrough all the time.
